The study provides a deeper understanding of how key proteins interact within the cell and could, in the long term, support the development of new cancer therapies.Tue, 07 Apr 2026 08:00:06 +0200<p>The findings, published in the journal ACS Chemical Biology, show how a central protein can block apoptosis &ndash; the process that normally causes cancer cells to die.</p><p>Apoptosis is a form of programmed cell death that plays a crucial role during embryonic development, in removing old or damaged cells, and in enabling the immune system to function properly. When apoptosis does not work as it should, as in many cancers, cells can divide uncontrollably and form tumours.</p><p>Many cancer treatments, such as chemotherapy and radiotherapy, work by causing damage or stress in cells that triggers apoptosis. However, many tumours manage to evade this form of cell death as well, making them resistant to treatment.</p><h2 id="info0" data-magellan-target="info0">Blocking death-inducing proteins</h2><p>One of the most important proteins controlling apoptosis is the cell‑killing protein Bax. Once activated, Bax can initiate apoptosis by forming pores in the membranes of mitochondria. Another key protein from the same family, the cell‑protective protein Bcl‑2, instead prevents Bax from killing harmful cells. In nearly half of all human cancers, one of the underlying problems is an increased production of Bcl‑2, which promotes tumour growth and often leads to poor response to therapy.</p><div class="mediaflowwrapper bildlink halfwidthsquareright"><div class="bildImage"></div><div class="bildText"><p>Gerhard Gr&ouml;bner, Professor at the Department of Chemistry, researches biological membranes, focusing on proteins involved in cell death.</p><span class="bildPhotografer"><span class="photo">Image</span>Mattias Pettersson</span></div></div><p>&ldquo;In our research, we have used advanced neutron experiments to show how Bcl‑2 protects cancer cells by blocking the death‑inducing proteins that are most often activated by therapy,&rdquo; says Gerhard Gr&ouml;bner, professor at Ume&aring; University and lead author of the study.</p><p>The experiments show that Bcl‑2, which is located on the outer surface of the mitochondria, can capture and bind several Bax proteins at the same time. This makes the inhibition of cell death more efficient than previously thought. Cancer cells do not need to produce extremely large amounts of Bcl‑2 to protect themselves &ndash; even a moderate increase can be sufficient.</p><h2 id="info1" data-magellan-target="info1">Opens up for new cancer treatments</h2><p>The researchers also investigated how the composition of the mitochondrial membrane affects the interaction between the proteins. One particular lipid, cardiolipin, can promote apoptosis and help Bax form pores in the membrane. However, even in membranes containing cardiolipin, a sufficiently high level of Bcl‑2 can still prevent cell death.</p><p>&ldquo;In the longer term, this type of knowledge could open up new opportunities for cancer treatment, for example by targeting Bcl‑2 and its protective function,&rdquo; says Gerhard Gr&ouml;bner.</p><p>The study was carried out in collaboration between researchers from Ume&aring; University, Lund University, the European Spallation Source (ESS) in Lund, the ISIS Neutron and Muon Source and Diamond Light Source in the United Kingdom, and the Institut Laue‑Langevin (ILL) in France.</p><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="3d9f9a48-969c-4927-b46d-f68c3821231e" data-contentname="">{}</div>https://www.umu.se/en/news/the-protein-that-helps-cancer-cells-survive-treatment2_12168639/https://www.umu.se/en/news/oliver-billker-awarded-the-torgny-och-lena-stigbrand-prize_12168901/Professor Oliver Billker at the Department of Molecular Biology has been awarded the Torgny and Lena Stigbrand Prize at Umeå University in 2026 for his contributions to malaria research.Thu, 02 Apr 2026 12:51:06 +0200<div class="mediaflowwrapper bildlink halfwidthsquareright"><div class="bildImage"><picture><source srcset="/contentassets/b41d9df5fed74c22b207d5110f0585c1/billiker_oliver_9193_180905_mpn2.jpg?format=webp&amp;mode=crop&amp;width=640 640w, /contentassets/b41d9df5fed74c22b207d5110f0585c1/billiker_oliver_9193_180905_mpn2.jpg?format=webp&amp;mode=crop&amp;width=854 854w, /contentassets/b41d9df5fed74c22b207d5110f0585c1/billiker_oliver_9193_180905_mpn2.jpg?format=webp&amp;mode=crop&amp;width=1280 1280w" type="image/webp" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"><source srcset="/contentassets/b41d9df5fed74c22b207d5110f0585c1/billiker_oliver_9193_180905_mpn2.jpg?mode=crop&amp;width=640 640w, /contentassets/b41d9df5fed74c22b207d5110f0585c1/billiker_oliver_9193_180905_mpn2.jpg?mode=crop&amp;width=854 854w, /contentassets/b41d9df5fed74c22b207d5110f0585c1/billiker_oliver_9193_180905_mpn2.jpg?mode=crop&amp;width=1280 1280w" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"></picture></div><div class="bildText"><p>Oliver Billker, Professor at the Department of Molecular Biology.</p><span class="bildPhotografer"><span class="photo">Image</span>Mattias Pettersson</span></div></div><p>Oliver Billker&rsquo;s research focuses on gaining a deeper understanding of the biology of malaria parasites and how they interact with the mosquitoes that transmit them.

A new research project at Umeå University aims to find out. Professor Florian Schmidt at the Department of Applied Physics and Electronics has been awarded SEK 12 million from the Swedish Energy Agency to investigate how low‑quality biomass can be combusted in a way that enables efficient carbon dioxide capture – and ideally leads to negative emissions.Tue, 31 Mar 2026 18:42:39 +0200<p>The project is carried out in close collaboration with researchers from Lund University, Lule&aring; University of Technology, the Research Institutes of Sweden (RISE), and several industrial partners.</p><h2 id="info0" data-magellan-target="info0">Over 25 million tonnes of negative emissions</h2><p>Bioenergy with carbon capture and storage or utilization (BECCUS) is identified as one of Sweden&rsquo;s most promising climate solutions. The potential is significant: the technology could deliver more than 25 million tonnes of negative CO₂ emissions per year &ndash; meaning it removes more CO₂ from the atmosphere than it emits (across the biomass lifecycle).</p><p>One of the most interesting methods for BECCUS is so‑called oxy‑fuel combustion, where fuel is burned in pure oxygen instead of air. This produces a flue gas with much higher concentrations of carbon dioxide, making capture, storage or reuse (for example, to produce electrofuels) considerably simpler and more cost‑effective.</p><p class="quote-center">What's unique is that we will explore how the technology could be implemented in Sweden</p><h2 id="info1" data-magellan-target="info1">Focusing on challenging fuel mixtures</h2><p>The project focuses on fluidized-bed combustion, a technology already widely used in industry and better suited than traditional methods for handling heterogeneous and difficult, ash-rich biomass.

The method addresses a long-standing technical challenge in cell research: until now, scientists have usually only been able to analyse each cell once, which has made it difficult to study how individual cells change or respond to different experimental conditions.</p><p>&ldquo;All cells are different, and understanding those differences is key to understanding disease,&rdquo; says Linas Mazutis.</p><h2 id="info0" data-magellan-target="info0">Small capsules keep the cells' DNA intact</h2><p>The new technology is based on an innovation that the researchers call semi-permeable capsule technology, using microscopic capsules each containing a single cell. The capsules have a liquid core surrounded by a thin, porous membrane. Small molecules, such as enzymes and chemical reagents, can pass through the membrane, while larger molecules like DNA and RNA are retained inside.</p><p>This makes it possible to analyse hundreds of thousands of individual cells simultaniously using standard laboratory equipment. The single cells can be treated and analysed multiple times without being lost or contaminated, something that has not been possible with earlier droplet-based techniques.</p><p>&ldquo;The capsules combine the speed of microfluidics &ndash; a technology that works with extremely small liquid volumes &ndash; with the flexibility of traditional laboratory workflows,&rdquo; says Linas Mazutis. &ldquo;This makes it possible to carry out advanced molecular biology workflows step by step, while keeping each cell&rsquo;s genetic material isolated.&rdquo;</p><h2 id="info1" data-magellan-target="info1">Easier to identify rare cell types</h2><p>The researchers also show that cells can be kept alive inside the capsules for extended periods, or broken down for genetic analysis. In addition, they introduce a new RNA sequencing approach that makes it easier to identify fragile or rare cell types &ndash; cells that often disappear when using existing methods.</p><p>According to the researchers, the technology is both simple and scalable, making it suitable for widespread use in biological and medical research. In the longer term, it could contribute to deeper insights into how diseases arise at the cellular level and help pave the way for more precise and personalised treatments. For example, researchers could use the method to study how individual cancer cells in the same tumour respond differently to a drug, or to identify rare immune cells that drive disease but are often missed by existing techniques.</p><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="9727e99d-5e04-4781-b930-94e540b95454" data-contentname="">{}</div>https://www.umu.se/en/news/capsule-technology-opens-new-window-into-individual-cells_12164688/https://www.umu.se/en/news/virginia-dignum-we-need-a-more-mature-conversation-about-ai_12164480/In her new book The AI Paradox, Virginia Dignum, Professor of Responsible AI at Umeå University, calls for a more nuanced public conversation about artificial intelligence.

Now, students at Umeå University have transformed this research into a computer game, making microbial dynamics visible and playable.Tue, 10 Mar 2026 10:31:19 +0100<p>In the microscopic world, bacteria often compete for nutrients and other essential molecules. At the same time, they can also cooperate,&nbsp; using by-products released by other bacteria in the same environment. Understanding when bacteria compete versus cooperate, and how they respond to their environment is the subject of research carried out by Josephine Solowiej-Wedderburn, postdoctoral fellow, and Eric Libby, associate professor, both affiliated with the Integrated Science Lab (IceLab) at Ume&aring; University, and the Department of Mathematics and Mathematical Statistics.</p><p>Because these processes cannot be directly observed in detail, they are often investigated using mathematical models.

After the experiments with shrimp and fish, the next step may be to grow mushrooms or vegetables, for example. Olivier Keech hopes that the project will have a ripple effect in other parts of Sweden and the world.</p><p>&ldquo;What excites me the most with this project is the win for everybody.

A new international study published in Science, with contributions from Umeå University, shows that this surge was driven primarily by a temporary weakening of the atmosphere’s ability to remove methane, combined with climate-driven increases in natural emissions in Africa, Asia, and the Arctic.Mon, 09 Feb 2026 13:00:05 +0100<div class="mediaflowwrapper bildlink"><div class="bildImage"></div><div class="bildText"><p>It was not primarily emissions from fossil fuels that caused the temporary increase in methane, but changes in the atmosphere combined with a wetter climate.</p><span class="bildPhotografer"><span class="photo">Image</span>Wirestock on Freepik</span></div></div><p>Methane is the second most important human-driven greenhouse gas after carbon dioxide. In the early 2020s, its levels in the atmosphere increased sharply, reaching a peak that researchers can now explain.</p><p>The atmosphere contains hydroxyl (OH) radicals that act as the main &ldquo;cleaning agent&rdquo;, breaking down methane. During the covid-19 lockdowns, emissions of nitrogen oxides and other air pollutants from transportation decreased. These pollutants are needed to form OH radicals through chemical reactions involving sunlight, ozone and water vapour.</p><p>When OH levels dropped, the atmosphere became less effective at removing methane, allowing it to accumulate faster.</p><p>Analyzing satellite observations, ground-based measurements, atmospheric chemistry data, and using advanced computer models, the researchers found a sharp decline in OH radicals during 2020&ndash;2021. This explains around 80 percent of the year-to-year variation in methane concentration growth.

An extended La Ni&ntilde;a period from 2020 to 2023 brought wetter-than-average conditions across much of the tropics, expanding flooded areas and increasing methane emissions from wetlands and inland waters, which are the largest single methane source around the world at present.</p><p>The largest increases occurred in tropical Africa and Southeast Asia, while Arctic freshwaters also showed significant growth.</p><h2 id="info1" data-magellan-target="info1">Weaknesses in current models</h2><p>The findings expose important weaknesses in current methane emission models, many of which underestimated wetland emissions during this period.</p><p>&ldquo;Our current models for methane in rivers are still primitive compared to other ecosystems.

One treatment already used in healthcare is CAR T-cell therapy. In this approach, T cells are extracted from a patient&rsquo;s blood, reprogrammed to attack cancer cells, and then returned to the body.</p><p>To create better and more effective CAR T cells, researchers have so far conducted experiments in mice, but the results do not always translate to humans.</p><h2 id="info0" data-magellan-target="info0">"Needles in a haystack"</h2><p>Johan Henriksson&rsquo;s research group is working with a new technique called single-cell analysis. It involves identifying CAR T cells in which a gene has accidentally been knocked out during production. By studying these cells, the researchers can learn which genes can aid best in treating cancer. The method is a modernised version of an older screening technique that Johan Henriksson became interested in through a collaboration with Laura Carroll, who studies bacteria at the Department of Clinical Microbiology.</p><p>&ldquo;We are looking for needles in a haystack. But the technology we&rsquo;ve developed makes this project finally possible,&rdquo; he says.</p><p>To find these rare cells, Johan Henriksson and his colleagues will need to build the largest single-cell database ever created &ndash; twenty times larger than the well-known Human Cell Atlas, which was developed by nearly 1,000 laboratories together.</p><h2 id="info1" data-magellan-target="info1">More affordable cancer treatment</h2><p>&ldquo;The technology is extremely expensive, so this is really just a pilot project. Once we&rsquo;ve shown that the method delivers useful data, we hope that companies can take over and scale up the technology. Much of the research at Ume&aring; University is only possible thanks to generous contributions from the Kempestiftelserna foundations, which originate from MoDo and the paper industry. It would be fantastic if the data we generate could lead to new businesses in V&auml;sterbotten and give something back,&rdquo; says Johan Henriksson.</p><p>According to him, the project has great potential to accelerate the development of next-generation CAR T cells. The need for effective and, above all, more affordable cancer treatments is enormous. Today, CAR T-cell therapy for a single patient can cost up to SEK 5 million.</p><p>&ldquo;If we can improve efficiency and reduce side effects, this could make the treatment available to more patients. CAR T cells also have the potential to cure other diseases that are difficult to target with conventional drugs,&rdquo; says Johan Henriksson.</p>https://www.umu.se/en/news/faster-and-safer-development-of-car-t-cells-against-cancer_12149253/https://www.umu.se/en/news/safer-dairy-products-with-fewer-chemicals_12148827/Bacteria in the dairy industry can lead to disease and food waste.

Inspired by this tradition, the Ume&aring; team set out to investigate how such methods could be reimagined for today&rsquo;s needs. Their work, supported by UmArts&rsquo; Small Visionary Projects program, focuses on a modular formwork system built from wood and textile.

The landscape is dotted with lakes and covered in sediment brought by the ice: sand, gravel and plenty of boulders. A news study from Ume&aring; University shows that this creates natural barriers that disrupt the flow of water. It also hinders the transport of sediment and the dispersal of plant seeds. All of this affects both the shape of the streams and the mix of plant types found along the shores.</p><p>&ldquo;We found that these landscapes are naturally fragmented, and that local conditions &ndash; such as sediment type and proximity to lakes &ndash; play a much larger role than previously thought,&rdquo; says Lina Polvi Sj&ouml;berg.</p><h2 id="info0" data-magellan-target="info0">The streams do not become wider</h2><p>Together with researcher Lovisa Lind, she studied two catchments in northern Sweden, Bjurb&auml;cken and Hjuks&aring;n, located above and below the highest coastline after the last glaciation.

But overall, the presence of lakes and coarse glacial deposits breaks up the expected downstream trends,&rdquo; says Lina Polvi Sj&ouml;berg.</p><p>The study shows that lakes stop the transport of plant seeds by water.

What started as a conversation quickly evolved into a collaboration of growing scope and significance.</p><p>Acne arises from several interacting factors. A key cause is an imbalance in the skin&rsquo;s microbiome. The bacterium <em>Propionibacterium acnes</em> can proliferate and form a protective biofilm, which contributes to the disease and makes antibiotic treatment more difficult.</p><p>Vakona&rsquo;s product is based on research by Dr. Oleg Alexeyev, Department of Medical Biosciences, and is designed as a skincare solution using a naturally occurring bacterial enzyme that breaks down the protective biofilm formed by <em>P. acnes</em>. Their need for structural biology expertise aligned perfectly with Magnus&rsquo;s research group&rsquo;s ambition to make a technological leap in cryo-electron microscopy (Cryo-EM), a method that has become central to the project.</p><h2 id="info0" data-magellan-target="info0">Fundamental research with clear application</h2><p>For Magnus, whose background is in structural enzymology, the project has been a welcome step toward research with direct societal relevance. Working with an enzyme that could potentially be used in acne treatment makes the research easier to communicate &mdash; to both funders and the general public.</p><p>&ldquo;It&rsquo;s exciting to be able to describe your research in one sentence, we&rsquo;re developing a therapy for acne. It makes it easier to explain and sparks interest.&rdquo;</p><p>The collaboration has also led to new research funding. Magnus and Oleg Alexeyev were awarded SEK 1.1 million from the Kempe Foundations to fund a two-year postdoctoral position fully dedicated to the Vakona project. Magnus also supervises a PhD student working on the project with support from the university&rsquo;s structural biology platform.</p><h2 id="info1" data-magellan-target="info1">New methods, new perspectives</h2><p>The project has marked a technical leap for Magnus&rsquo;s lab, which has traditionally focused on nuclear magnetic resonance spectroscopy. Through the collaboration with Vakona, the group has now established Cryo-EM as a new method, opening up significant opportunities for other projects as well.</p><p>&ldquo;This step will be hugely important for us. We already have other collaborations using the technique, including one with KTH, where we hope to publish soon.&rdquo;</p><p>At the same time, the partnership has brought new challenges, particularly around patents and publishing. Balancing corporate interests has influenced research methods, and numerous meetings were needed to find a middle ground between openness and confidentiality.</p><p>&ldquo;You have to align your goals. Industry wants to make money, we want to publish. But we&rsquo;ve found a good plan for that.&rdquo;</p><h2 id="info2" data-magellan-target="info2">Lessons learned and looking ahead</h2><p>For Magnus, the project has been both educational and inspiring. It&rsquo;s his first time collaborating with a company, offering insights into how researchers and businesses can work together and how to navigate the intersection between academic freedom and commercial interests.</p><p>&ldquo;There&rsquo;s a societal push for these kinds of collaborations. It&rsquo;s important to understand the basic premises before entering a project.&rdquo;</p><p>He encourages other researchers to seize the opportunity if it arises but to be diligent about discussing patents and publishing from the outset.</p><p>&ldquo;It&rsquo;s a solid setup. We hope the collaboration leads to a strong publication, that the company secures funding, and can hire people. It&rsquo;s a win-win.&rdquo;</p><h2 id="info3" data-magellan-target="info3">An innovation ecosystem</h2><p>The partnership between Ume&aring; University and Vakona illustrates how academic research can contribute to a local innovation ecosystem. Growth in spin-off companies can create new jobs for trained researchers, strengthening both the university&rsquo;s role and regional development.</p><p>&ldquo;If we can contribute in that way and help create a job market, that&rsquo;s fantastic.&rdquo;</p><p>The project also demonstrates that research with clear applications can have greater impact both within academia and beyond.</p><div class="mediaflowwrapper bildlink"><div class="bildImage"><picture><source srcset="/contentassets/1929bd7b551a4972a1bb716b1920f684/akne2.jpg?format=webp&amp;mode=crop&amp;width=640 640w, /contentassets/1929bd7b551a4972a1bb716b1920f684/akne2.jpg?format=webp&amp;mode=crop&amp;width=854 854w, /contentassets/1929bd7b551a4972a1bb716b1920f684/akne2.jpg?format=webp&amp;mode=crop&amp;width=1280 1280w" type="image/webp" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"><source srcset="/contentassets/1929bd7b551a4972a1bb716b1920f684/akne2.jpg?mode=crop&amp;width=640 640w, /contentassets/1929bd7b551a4972a1bb716b1920f684/akne2.jpg?mode=crop&amp;width=854 854w, /contentassets/1929bd7b551a4972a1bb716b1920f684/akne2.jpg?mode=crop&amp;width=1280 1280w" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"></picture></div><div class="bildText"><p>Acne mainly affects teenagers, especially during puberty when hormonal changes increase sebum production.</p><span class="bildPhotografer"><span class="photo">Image</span>plainpicture</span></div></div>https://www.umu.se/en/news/collaboration-with-biotechnology-companies-opens-new-doors-for-umea-chemist_12141643/https://www.umu.se/en/news/methane-production-may-increase-as-arctic-lakes-warm_12141395/A warmer and wetter climate makes lakes more productive – which in turn leads to more methane being released from sediments.

Millions of families still use traditional and inefficient cookstoves, which pollute homes with smoke, cause respiratory illness, place heavy burdens on women who collect firewood, and contribute to environmental degradation. In his doctoral thesis at Ume&aring; University, Natxo Garc&iacute;a-L&oacute;pez examines how more sustainable bioenergy solutions can address these challenges.</p><p>His work combines laboratory studies, field experiments in Rwanda, systematic reviews, and a perspective study that explores new bioenergy approaches. The findings highlight the value of improved cookstoves, which burn more efficiently and reduce both emissions and health risks. Still, Garc&iacute;a-L&oacute;pez&rsquo;s research extends beyond stoves to integrated energy solutions. In his thesis, he broadens the perspective to the community level, examining how bioenergy can be scaled and integrated into broader frameworks of rural development and energy access.</p><p>By integrating agroforestry with bioenergy, he outlines a model in which farmland serves more than its traditional role of producing food. Sustainably managed trees and crops can supply households with cleaner cooking fuel while also generating surplus biomass for electricity production through gasification. In this way, everyday cooking becomes directly connected to rural development, energy security and access to modern energy services.</p><p>&nbsp;&ldquo;It&rsquo;s a blueprint for scalable, community-level energy solutions,&rdquo; he says.</p><h2 id="info0" data-magellan-target="info0">Fieldwork challenging but rewarding</h2><p>Conducting research in rural Rwanda was demanding, both logistically and scientifically. It involved traveling to remote areas, working with limited resources, and operating advanced instruments under difficult conditions. At the same time, it created opportunities to work closely with local communities and to collect data directly from rural households, offering valuable insights into their everyday challenges.</p><p>&ldquo;It gave me a first-hand understanding of the challenges rural households and of how cleaner technologies can truly make a difference,&rdquo; says Garc&iacute;a-L&oacute;pez.</p><h2 id="info1" data-magellan-target="info1">Beyond technology &ndash; a matter of people&rsquo;s lives</h2><p>Although the thesis devotes considerable attention to the technical analysis of combustion processes, emissions and particles, its implications reach far beyond engineering. It sheds light on the everyday realities of people in rural Africa, particularly the lack of access to modern energy services such as clean cooking and electricity. The findings also resonate with several pressing global challenges &ndash; from public health and gender equality to climate change and environmental sustainability.</p><p>&ldquo;Cleaner cookstoves can make indoor environments safer, reduce disease risks, and help preserve both forests and climate,&rdquo; says Garc&iacute;a-L&oacute;pez.</p><p>Beyond the technical contributions, Garc&iacute;a-L&oacute;pez hopes that his work can spark dialogue among decision-makers and practitioners. Its true impact will depend on how it is received by the research community, policymakers, NGOs and other actors, but his ambition is that it will make a positive difference for people in rural sub-Saharan Africa who remain without access to modern energy services.</p><h2 id="info2" data-magellan-target="info2">The way forward</h2><p>While the dissertation provides new evidence and technical insights, it also opens the door to future research directions.

Now, researchers from the USA, China, Singapore and Sweden have succeeded in creating a variety of advanced thin metamaterials which not only block solar radiation but also emit heat, hence lowering the indoor temperature. One of the materials can be sprayed or brushed from paint.</p><p>&ldquo;A roof painted with the specially designed material maintained an indoor temperature 5.6 degrees lower than another building painted with conventional white paint,&rdquo; says Max Yan, Associate Professor at Ume&aring; University and co-author of the study published in the scientific journal Nature.</p><h2 id="info0" data-magellan-target="info0">Machine learning creates complex structures</h2><p>Metamaterials are artificially engineered materials with properties that are superior to those found in natural materials. Developing cooling metamaterials has previously been a time-consuming process where researchers had to rely on trial and error. The new method is based on machine learning and artificial intelligence, which in just a few days can generate thousands of complex structures with the desired properties of reflecting solar radiation and emitting thermal radiation. The best candidates are then identified in terms of mass producibility and cost.</p><div class="mediaflowwrapper bildlink halfwidthsquareright"><div class="bildImage"></div><div class="bildText"><p>Max Yan, Associate Professor at the Department of Applied Physics and Electronics.</p><span class="bildPhotografer"><span class="photo">Image</span>Hans Karlsson</span></div></div><p>The new paint can provide significant energy savings by reducing the need for air conditioning. Calculations show that if the paint is applied to the roof of a typical four-storey apartment building with a roof area of 780 square metres in Bangkok, it could save about 12,000 kilowatt hours of electricity annually.</p><p>In addition to being used on buildings, the new paint can be applied to other objects, such as cars, trains, or machines.

This determines how it mixes, stores heat, exchanges gases, and cycles nutrients. Hypsography makes it possible to model lake functions and has allowed researchers to uncover new patterns in the composite, such as how lakes in cold, glaciated regions differ structurally and functionally from those in warmer climates.</p><h2 id="info1" data-magellan-target="info1">Lakes mirror land more than oceans</h2><p>The models also reveal a striking insight: the combined structure of the world&rsquo;s lakes more closely mirrors land than oceans. Unlike oceans, which are dominated by depth, most lake area worldwide is shallow &ndash; a feature that strongly influences their ecological and climatic roles.</p><p>&ldquo;This work bridges the gap between the complexity of individual lakes and the patterns that emerge when you analyse millions of them. It&rsquo;s like zooming out and suddenly seeing hidden structures and responses take shape,&rdquo; says Cristian Gudasz.</p><p>The concept of &Uuml;ber-lakes makes it possible to not only understand how the world&rsquo;s lakes reflect environmental change, but also how they can influence it.</p><p>&ldquo;We can average their properties, but what really matters is that composite lakes reveal how lakes interact with the climate system in a way that is more than the sum of individual lakes. Understanding how they function together as a global system gives us a powerful new lens on climate feedback and ecological stability,&rdquo; says Cristian Gudasz.</p><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="59773fc6-412d-4754-9fe7-798e217879ee" data-contentname="About the article">{}</div>https://www.umu.se/en/news/millions-of-lakes-reveal-new-patterns-when-viewed-as-one_12128601/https://www.umu.se/en/news/how-small-changes-in-atoms-improve-hydrogen-production_12113583/Researchers at Umeå University have identified the inner workings of a highly efficient and stable catalyst for hydrogen production, a process central to many sustainable energy initiatives.Wed, 18 Jun 2025 09:28:51 +0200<div class="mediaflowwrapper bildlink"><div class="bildImage"><picture><source srcset="/contentassets/d29b8807829142da85ce4f87194adda9/mouna-rafei-press-release3.jpg?format=webp&amp;mode=crop&amp;width=640 640w, /contentassets/d29b8807829142da85ce4f87194adda9/mouna-rafei-press-release3.jpg?format=webp&amp;mode=crop&amp;width=854 854w, /contentassets/d29b8807829142da85ce4f87194adda9/mouna-rafei-press-release3.jpg?format=webp&amp;mode=crop&amp;width=1280 1280w" type="image/webp" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"><source srcset="/contentassets/d29b8807829142da85ce4f87194adda9/mouna-rafei-press-release3.jpg?mode=crop&amp;width=640 640w, /contentassets/d29b8807829142da85ce4f87194adda9/mouna-rafei-press-release3.jpg?mode=crop&amp;width=854 854w, /contentassets/d29b8807829142da85ce4f87194adda9/mouna-rafei-press-release3.jpg?mode=crop&amp;width=1280 1280w" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"></picture></div><div class="bildText"><p>Mouna Rafei, doctoral student at the Department of Physics.</p><span class="bildPhotografer"><span class="photo">Image</span>Eduardo Gracia</span></div></div><p>In a recently published study in the scientific journal Communications Materials, researchers have found a way to improve catalysts for water electrolysis, which splits water into hydrogen and oxygen to generate clean fuel.</p><p>The study tackles a long-standing mystery: how can catalysts made of nickel, iron and molybdenum maintain their exceptional activity and continue to efficiently split water, even after a significant portion of their molybdenum is lost during operation.</p><p>Hydrogen is an excellent energy source, and its production from water through electrolysis forms the basis of several sustainable energy initiatives.

Each region has its own species and environmental conditions. Yet, beneath this variety, there is a universal organising pattern, new research led from Ume&aring; University shows. This finding can help scientists explore how biodiversity has been shaped through time and how biodiversity can response against global change.</p><p>The planet is divided into large biogeographical regions, or bioregions, separated by oceans, mountain ranges or extreme climates. These barriers limit the movement of species, turning each region into a natural experiment where distinct groups of species have evolved under different conditions, timescales, and histories.</p><p class="quote-center">It seems these cores provide optimal conditions for species survival and diversification.</p><p>In this study, an international collaboration of research institutions from Sweden, Spain, and the UK examined species from very different life forms in bioregions across the world: amphibians, birds, dragonflies, mammals, marine rays, reptiles, and trees. Given the vast differences in life strategies &ndash; some species fly, others crawl, swim, or remain rooted &ndash; and the contrasting environmental and historical backgrounds of each bioregion, the researchers expected that patterns of species distribution would vary widely across bioregions. Surprisingly, they found the same pattern everywhere.</p><div class="mediaflowwrapper bildlink"><div class="bildImage"></div><div class="bildText"><p>The researchers were surprised to find that the pattern of species distribution was the same, regardless of the life form.</p><span class="bildPhotografer"><span class="photo">Image</span>Wirestock/Freepik</span></div></div><p>&ldquo;In every bioregion, there is always a core area where most species live.

While this has long been a central theory in ecology, global empirical evidence has been scarce. This study provides broad confirmation across multiple branches of life and at a planetary scale.</p><p>&ldquo;The predictability of the pattern and its association with environmental filters can help to understand better how biodiversity may respond to global change,&rdquo; says Joaqu&iacute;n Calatayud, co-author from Rey Juan Carlos University.</p><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="8971d0f2-f0a4-4a4d-9539-b338316da5ba" data-contentname="About the study">{}</div>https://www.umu.se/en/news/one-single-rule-helps-explain-life-from-ocean-depths-to-open-savannas_12106068/https://www.umu.se/en/news/new-ai-research-secures-privacy_12105625/An international research team, led by Jian-Feng Mao, have developed PlantLncBoost, a new computational tool that helps to identify long non-coding RNAs in plants. These RNAs are crucial for numerous biological processes but differ a lot between different plant species. PlantLncBoost addresses this challenge with very high accuracy offering new possibilities for genomic studies in plants. These findings were recently published in the journal New Phytologist.Wed, 11 Jun 2025 14:59:57 +0200<p>Long non-coding RNAs, called lncRNAs, are transcribed from DNA as other RNAs but they do not carry instructions for proteins. Instead, they help controlling genes, guide plant development and are involved in plant responses to stress like drought or heat. Identifying these lncRNAs has been difficult because their genetic sequences vary a lot between different plant species.</p><p>The team around Jian-Feng Mao tackled the problem using machine learning, a type of artificial intelligence that is trained on large amounts of data to find patterns. They analysed over 1,600 different features of lncRNAs and identified just three key features that could effectively distinguish lncRNAs from RNAs containing the code for a protein.</p><h3>Identification of sequence patterns using mathematical parameters</h3><p>What makes PlantLncBoost particularly innovative is its use of mathematical parameters to capture intrinsic sequence properties beyond traditional biological features. The research team used so called Fourier transformation-based approaches. That allowed them to detect patterns in the RNA sequences that are consistent across diverse plant species despite of the high variability in the genetic sequences.</p><p class="quote-center">We have developed a tool that achieves both high accuracy and strong generalization capabilities.</p><p>&ldquo;Through systematic evaluation of multiple machine learning algorithms and rigorous parameter optimization, we have developed a tool that achieves both high accuracy and strong generalization capabilities,&rdquo; explains Jian-Feng Mao, Associate professor at Ume&aring; University who established his lab at the Ume&aring; Plant Science Centre in 2023.</p><p>To make sure their new tool worked, the team tested PlantLncBoost on datasets from 20 different plant species. It correctly identified lncRNAs with over 96% accuracy, significantly outperforming existing tools. The tool even recognised nearly all 358 long lncRNAs that had been experimentally validated before, including those from twelve species that were not included in the training set used to develop the tool.</p><h3>New possibilities to analyse long non-coding RNAs across species</h3><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="45573d4b-e151-4284-b6fb-a637ada105eb" data-contentname="Xue-Chan Tian">{}</div><p>&ldquo;Developing PlantLncBoost was an exciting opportunity to apply machine learning to solve a complex biological problem,&rdquo; says first author Xue-Chan Tian, who completed this work as part of her PhD thesis at Beijing Forestry University. &ldquo;My doctoral programme focused on combining advanced computational methods with plant genomics to extract meaningful biological insights from complex sequence data.&rdquo;</p><p>The project brought together experts in genomics, bioinformatics and computer science from around the world, including researchers from Sweden, China and Brazil. The tool is now freely available to the scientific community and has been integrated in a larger analysis workflow that was developed earlier by Jian-Feng Mao&rsquo;s group. It allows not only to identify but also to characterise lncRNAs in plants. By implementing PlantLncBoost in this workflow, researchers can now identify long non-coding RNAs from different plant species much more accurate, making it easier to compare and analyse them.</p>https://www.umu.se/en/news/new-computational-tool-helps-to-identify-long-non-coding-rnas_12104417/https://www.umu.se/en/news/laura-bacete-cano-becomes-a-member-of-the-young-academy-of-sweden_12100337/She wants to help shape the academic environment and highlight the importance of research in plant cell and molecular biology.

You have been elected as new member to the Young Academy of Sweden. What does this mean for you?</strong></em></p><p>It means a lot, both professionally and personally. I see it as a chance to work with researchers from different fields and backgrounds, and to take part in discussions that go beyond my own research. It is also a way to help shape the academic environment in Sweden and beyond.</p><p><em><strong>- What motivated you to apply for the membership?</strong></em></p><p>I was really drawn to how the Academy brings together researchers from different fields to work on questions that matter for science and for society. The focus on research policy, public engagement, and international collaboration felt like a good match for the kind of work I want to do alongside my research. It is quite rare to find a space where you can have those kinds of conversations across disciplines in a structured but open way.</p><p>I also noticed that there was not anyone in the Academy with a background in plant cell and molecular biology. It is a field that is key both for fundamental science and for real-world issues like sustainable agriculture and climate resilience. Sweden has a lot of excellent research in this area, so it felt important to have that perspective represented too.</p><p><em><strong>- What responsibilities come with your membership?</strong></em></p><p>There is a strong expectation to be actively involved, which I really appreciate. In the next months, I will take part in a few in-person meetings held in different parts of Sweden. These gatherings are the heart of the Academy&rsquo;s work and where many ideas and decisions take shape. One thing I really like is that new members are expected to contribute from the beginning, whether that is through participating in policy discussions, taking part in outreach, or helping develop new initiatives. It feels like a very open and hands-on environment.</p><p>For me, another important part is improving my Swedish. Even though the other members are happy to speak English when needed, Swedish is the main working language of the Academy. I am really looking forward to using the language more and getting better at it through this role. It feels like a great opportunity to learn in a supportive setting.</p><p class="quote-left">I think scientists have a responsibility to communicate with the public.</p><p><em><strong>- Do you plan to engage with the public or policymakers through your new role?</strong></em></p><p>Yes, absolutely. I think scientists have a responsibility to communicate with the public, and I have been involved in that kind of work before. But what I am especially looking forward to now is the chance to engage more directly with policymakers. That is not something that is always easy to do in everyday academic life. I am particularly interested in questions around how we support researchers, how we evaluate work, and how we build a research environment that people actually want to stay in; and also about how long-term thinking and evidence can play a stronger role in shaping decisions (for example, regarding new genomic techniques in agriculture). I also appreciate that the Academy works internationally, and I look forward to contributing to those collaborations through my own networks and experience.</p><p><em><strong>- What are you most looking forward to during your time in the academy?</strong></em></p><p>I&rsquo;m looking forward to working with people who care about the same kinds of questions, even if they come from completely different fields. The Academy seems like a rare space where people have time and freedom to talk about how science works, how it could work better, and what role it plays in society. I am also looking forward to the in-person meetings and the chance to get to know colleagues from other disciplines. I think those conversations can lead to unexpected ideas and collaborations, which is something I really enjoy.</p><p><em>Laura Bacete Cano, originally from Spain, is an Assistant Professor at Ume&aring; University and leads a research group at Ume&aring; Plant Science Centre, which she established in 2023.

A new research project, led by Olivier Keech, is addressing this question and aims at developing circular solutions for more sustainable and efficient food systems. With generous support from the Kamprad Family Foundation for Entrepreneurship, Research & Charity, the team wants to transform residues from the forest and food industries into high-quality animal feed by combining fermentation and pelleting techniques.Fri, 30 May 2025 11:41:10 +0200<p class="quote-center">Our goal is to support local industries, improve circularity and reduce the carbon footprint of food production in Nordic countries.</p><p>Biological residues such as sawdust from the forest industry, cereal bran from breweries, and municipal food wastes, accumulate during wood and food processing. Even though they are rich in carbohydrates, these wastes often have a low residual value because the presence of cellulose and lignins makes them difficult for animals to digest. A scientific team, led by Olivier Keech, plan to use the carbohydrates stored in these residues to create higher-value feed while supporting the development of a local, circular, and environmentally friendly economy.</p><p>&ldquo;Many of these organic residues contain a lot of fibres, a poorly accessible source of sugar. We plan to use a combination of modern chemical and biochemical techniques to break down the material and release the carbohydrates, which bacteria and yeast will then ferment and turn into valuable proteins&rdquo;, explains Olivier Keech, Associate Professor at Ume&aring; University and research group leader at Ume&aring; Plant Science Centre. &ldquo;The fermentation product will then be pelleted and used as animal feed.&rdquo;&nbsp;</p><h2 id="info0" data-magellan-target="info0">Fermented feed as a natural immune booster for farm animals</h2><p>The fermented feed has an additional value: it acts as a probiotic for animals. This means that it will naturally boost the immune system of the farmed animals. The researchers will analyse how feed fermented by different bacteria and yeast strains affects the animal&rsquo;s gut health and immune system. These bacteria and yeast strains each have unique traits and produce different substances during fermentation. By testing various combinations, they aim to tailor the feed recipe to the needs of different animals, primarily focusing on chicken, pigs and shrimps.</p><p>For this ambitious project, Olivier Keech is joined by three experts coming from different fields. Leif J&ouml;nsson, Professor at the Department of Chemistry, Ume&aring; University, will bring his expertise in hydrothermal catalysis, a process that uses hot, pressurised water to help break down cellulose-containing plant residues.</p><p>Volkmar Passoth, Professor at the Department of Molecular Sciences, Swedish University of Agricultural Sciences, is a food biotechnologist. He studies how microbial fermentation, especially from yeast, can enhance the quality of animal feed in circular production systems that aim to reuse resources rather than throwing them away.</p><p>The team is completed by Anders Kiessling, also Professor at the Swedish University of Agricultural Sciences. He works at the Department of Applied Animal Science and Welfare with sustainable animal nutrition sources and how nutrients can be recycled in closed farming systems. He collaborates with Olivier Keech already on another project focusing on integrated multi-trophic farming, a sustainable farming approach that combines different species from various levels of the food chain in one system.</p><h2 id="info1" data-magellan-target="info1">Combining lab experiments with tests in modern aquaculture systems</h2><p>&ldquo;We will first do several experiments in our respective labs. However, thanks to the pilot platform for research and development on sustainable food farming that we are setting up at &Ouml;stersj&ouml;fabriken in V&auml;stervik, we will quickly be able to test the quality of the newly produced feed in modern aquaculture systems focusing on shrimp and fish production,&rdquo; says Olivier Keech.</p><p>And he concludes: &ldquo;Our goal is to support local industries, improve circularity and reduce the carbon footprint of food production in Nordic countries. Ultimately, this should deliver a great product to the consumers. Thanks to the Kamprad Family Foundation for Entrepreneurship, Research &amp; Charity, we can hopefully soon come closer to reaching this goal".</p>https://www.umu.se/en/news/new-project-aims-to-turn-residues-into-high-quality-animal-feed_12098536/https://www.umu.se/en/news/advanced-coatings-boost-the-competitiveness-of-solar-thermal-energy_12094833/Researchers at Umeå University have developed new sustainable coatings that improve the performance of solar thermal collectors – strengthening solar heat's position as a climate-smart energy source.

By adjusting the size and shape of the pores, as well as the thickness of the coating, he has succeeded in increasing the light transmitted through the glass. At the same time, the coating&rsquo;s resistance to scratches, dirt and moisture is improved &ndash; factors that would otherwise reduce performance over time.</p><p>For the receiver, the thesis presents two solutions. One is an electroplated cobalt-chromium coating that absorbs light thanks to its surface structure.

Their findings suggest that adjusting clock-associated genes could help trees better synchronize with changing climates, offering new opportunities for forestry.

Research has suggested that this clock is important to regulate growth and the timing of &nbsp;important seasonal events, like for example bud formation in autumn and bud opening in spring. However, most of this research has been done in controlled greenhouse conditions and not outside in the field where plants are exposed to natural environmental conditions. In the field, as in the real world, temperature fluctuations, insect predation and other factors affect plant growth.</p><p>To address this, the researchers conducted an extensive study based on 68 poplar or aspen lines with different, modified properties. Among the genes that were modified were many associated with the circadian clock. These trees&rsquo; growth was studied in multiple greenhouse and field experiments over several years. The results clearly showed that the circadian clock has a strong role in regulating tree growth and the timing of seasonal events in the life of a tree, like the budding of leaves.</p><p>&ldquo;Our study is the first to combine datasets from greenhouse and field studies to show that multiple aspects of the circadian clock system influence tree growth and the timing of life-cycle events,&rdquo; says Bertold Mari&euml;n, lead author of the study. &ldquo;By applying statistical modelling to these datasets, we were able to pinpoint which circadian clock-associated genes impact tree growth or, for example, the time when leaves appear or change colour.&rdquo;</p><h3>Insights for Forestry and Climate Adaptation</h3><p>The study provides a new perspective on how trees use their circadian clock to coordinate their growth with the environment. For example, certain genetic modifications in key clock regulators changed the trees&rsquo; sensing of the day length and allowed trees to continue growing later into the season.</p><p>"This study is a proof-of-concept that trees conditioned to a particular length of day at a certain latitude can be adapted to a new latitude, effectively extending their growing season. This is especially useful at higher latitudes like in Northern Sweden where short growing seasons limit timber production," explains Maria E. Eriksson, last author of the study.</p><p class="quote-center">By properly incorporating our findings on the circadian clock into global vegetation models, we can improve predictions of how forests will respond to climate change.</p><p>Additionally, some gene modifications improved the trees&rsquo; resilience under environmental fluctuations. By focusing on these specific genes, it would be possible to breed tree varieties that are better adapted to rapid changes in the local climate, and to new growing locations, for example in other latitudes. &nbsp; &nbsp;</p><p>"In the future, forestry management could be improved by integrating trees&rsquo; circadian clocks and their natural growth cycles with traditional practices&rdquo;, says Eriksson. &ldquo;In this way, tree growth and resilience could be optimized in a changing world.&rdquo;</p><p>Beyond the implications for forestry, the study also has relevance for global vegetation models that predict forest growth and carbon storage. The importance of the clock in shaping trees&rsquo; sensitivity to environmental conditions is often underestimated in these models, according to Mari&euml;n. He concludes, &ldquo;By properly incorporating our findings on the circadian clock into global vegetation models, we can improve predictions of how forests will respond to climate change.&rdquo;</p><p>&nbsp;</p>https://www.umu.se/en/news/adjusting-trees-internal-clocks-can-help-them-cope-with-climate-change_12076832/https://www.umu.se/en/news/largest-study-to-date-shows-pharmaceutical-pollution-alters-migration-in-atlantic-salmon_12076632/Umeå researcher Jerker Fick, together with researchers at the Swedish University of Agricultural Sciences, SLU, has conducted the largest study to date investigating how pharmaceutical pollution affects the behaviour and migration of Atlantic salmon.

Several of the studies were conducted in Sweden.</p><p>The studies cover terrestrial, freshwater and marine habitats around the world, and all groups of organisms, from microbes and fungi to plants and invertebrates, fish, birds and mammals.

It is not only the increasing blooms of cyanobacteria that indicate this. An analysis of many years of monitoring data shows that phosphorus concentrations are increasing and the ratio of nitrogen to phosphorus is decreasing. A research group from the Umeå Marine Sciences Centre at Umeå University has analysed nutrient dynamics and how human activity has affected the situation.Tue, 06 May 2025 08:31:38 +0200<p>The Gulf of Bothnia, with its two sea basins the Bothnian Sea and the Bothnian Bay, has long been considered to be spared from eutrophication. At present, for example, the requirements for nitrogen removal only apply to the treatment plants located south of the Gulf of Bothnia. In 2022, a revised wastewater directive was issued in which the rules were tightened and will apply to all of Sweden's coastal areas. This has raised the question of where the situation in the Gulf of Bothnia is heading, and what we really know about it. There has been criticism against that nitrogen removal should also be required in the Gulf of Bothnia, but the results from the recently published study show that it is relevant to re-evaluate the issue of nitrogen removal in the Gulf of Bothnia as well.</p><div class="mediaflowwrapper bildlink"><div class="bildImage"><picture><source srcset="/contentassets/e91a7555fe26402f8ec008d4e781f539/vattenprovtagning_4075__210917_mjn2.jpg?format=webp&amp;mode=crop&amp;width=640 640w, /contentassets/e91a7555fe26402f8ec008d4e781f539/vattenprovtagning_4075__210917_mjn2.jpg?format=webp&amp;mode=crop&amp;width=854 854w, /contentassets/e91a7555fe26402f8ec008d4e781f539/vattenprovtagning_4075__210917_mjn2.jpg?format=webp&amp;mode=crop&amp;width=1280 1280w" type="image/webp" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"><source srcset="/contentassets/e91a7555fe26402f8ec008d4e781f539/vattenprovtagning_4075__210917_mjn2.jpg?mode=crop&amp;width=640 640w, /contentassets/e91a7555fe26402f8ec008d4e781f539/vattenprovtagning_4075__210917_mjn2.jpg?mode=crop&amp;width=854 854w, /contentassets/e91a7555fe26402f8ec008d4e781f539/vattenprovtagning_4075__210917_mjn2.jpg?mode=crop&amp;width=1280 1280w" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"></picture></div><div class="bildText"><p>Water sampling from the research vessel KBV 181.

If the amounts of phosphorus increase, the system will become nitrogen-sensitive, which means that the production of, for example, phytoplankton will increase if more nitrogen is added. In a nitrogen-sensitive system, the risks for problems with eutrophication increase significantly. One effect may be that potentially toxic algal blooms increase, as the imbalance between nitrogen and phosphorus favours nitrogen-fixing cyanobacteria. The study clearly shows that nitrogen sensitivity is increasing in both the Bothnian Sea and the Bothnian Bay, although the situation has not yet reached as far in the Bothnian Bay. In the Bothnian Sea, cyanobacteria blooms have already increased.</p><h3>Phosphorus-rich water from the south</h3><p>Why are we seeing this development in the Gulf of Bothnia? The explanation that may seem obvious is that the wastewater treatment plants' emissions have caused the problems. Therefore, a review of measurement data from water both upstream and downstream treatment plants was made at a large number of premises along the coast. It was not possible to trace the cause of the change in nutrient balance to the treatment plants. Does this show that the emissions from the treatment plants have no significance?</p><div class="mediaflowwrapper bildlink"><div class="bildImage"><picture><source srcset="/contentassets/e91a7555fe26402f8ec008d4e781f539/ulvon_algblomning2.jpg?format=webp&amp;mode=crop&amp;width=640 640w, /contentassets/e91a7555fe26402f8ec008d4e781f539/ulvon_algblomning2.jpg?format=webp&amp;mode=crop&amp;width=854 854w, /contentassets/e91a7555fe26402f8ec008d4e781f539/ulvon_algblomning2.jpg?format=webp&amp;mode=crop&amp;width=1280 1280w" type="image/webp" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"><source srcset="/contentassets/e91a7555fe26402f8ec008d4e781f539/ulvon_algblomning2.jpg?mode=crop&amp;width=640 640w, /contentassets/e91a7555fe26402f8ec008d4e781f539/ulvon_algblomning2.jpg?mode=crop&amp;width=854 854w, /contentassets/e91a7555fe26402f8ec008d4e781f539/ulvon_algblomning2.jpg?mode=crop&amp;width=1280 1280w" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"></picture></div><div class="bildText"><p>Cyanobacteria blooms increase when marine areas become nitrogen-sensitive.

"The measurement programs at the treatment plants are not designed to answer that question. In addition, there is a dilution effect from the large rivers, which further complicates the analysis."</p><p>What can be shown, however, is that some of the problems stem from the Baltic Proper. Through the passage around &Aring;land, phosphorus-rich water flows in from the Baltic Proper, causing the balance between nitrogen and phosphorus to change in the Bothnian Sea. Water also flows northwards in the area between the Bothnian Sea and the Bothnian Bay, the northern Quark. The already known problems in the Baltic Proper are thus spreading to the entire Gulf of Bothnia.</p><p>"The question is no longer IF the Gulf of Bothnia will have problems with eutrophication, but rather WHEN. Knowledge about nutrient conditions and ecosystem responses in the Gulf of Bothnia has so far been very limited. By compiling data from both Sweden and Finland, we have gained a clearer picture of how the situation has been, is and how it can be expected to develop," says Joakim.</p><h3>Advice for marine management</h3><p>The report contains a lot of concrete advice for marine management and arouses great interest among the authorities responsible for the marine environment in the Gulf of Bothnia.</p><p>"The report will provide input throughout the chain from mapping the conditions to planning measures linked to eutrophication. The fact that there is now nitrogen limitation in the Bothnian Sea is an important finding they have been able to make, together with the conclusion that the supply of nutrients from the Baltic Proper plays a major role in the nutrient situation in the entire Gulf of Bothnia. We will take this with us when we start the work of planning measures in the autumn. " says Anneli Sedin, environmental officer at the County Administrative Board of V&auml;sterbotten.</p><p>The researchers will now deepen their knowledge further through detailed studies of what is happening in the southern and northern Quark.</p><p>"This is where it all happens.

Between July 2025 and December 2028, researchers in Germany, Spain, and Sweden—including four experts from the Department of Applied Physics and Electronics at Umeå University—will work to optimize steel manufacturing processes. The goal: stronger, more cost-effective steel with a reduced environmental footprint.Fri, 14 Mar 2025 13:07:31 +0100<p>By utilizing a new type of ausferritic nanostructure, the steel becomes stronger and more robust while also being cheaper to produce. Additionally, the manufacturing process requires significantly less energy, leading to lower CO₂ emissions.</p><p class="quote-center">This method minimizes both energy consumption and CO₂ emissions while also being significantly cheaper</p><p>Compared to conventional mild steels, today&rsquo;s ultra-high-strength steels rely on a higher carbon content combined with a heat treatment (QT) that rapidly cools the material in an oil bath, resulting in a large carbon footprint&mdash;especially in countries that use fossil fuels in production.</p><p>"This new paradigm involves adding a high silicon content and hardening through austempering&mdash;cooling and heat-holding in a molten salt bath. For certain material dimensions, the ausferrite can begin forming during air cooling after hot rolling of bars or after hot forging and then be &lsquo;baked&rsquo; in air at a low temperature. This method minimizes both energy consumption and CO₂ emissions while also being significantly cheaper than all other through-hardening methods for steel," says Richard Larker, Associate Professor at the Department of Applied Physics and Electronics at Ume&aring; University, and the initiator of the project.&nbsp;</p><h3>Collaborations with Industry</h3><p>To ensure that ausferritic steels offer competitive advantages, AUSNANITE collaborates with several leading companies, including the Spanish steel bar manufacturer Sidenor, Epiroc, and Rototilt, where Richard Larker previously served as Head of Research. These partners will manufacture and test the steel under extreme loads, also subject to impact and wear.&nbsp;</p><h3>Part of the EU&rsquo;s Sustainable Materials Initiative</h3><p>The project aligns with the EU&rsquo;s Green Deal, as the high silicon content reduces the need for more critical alloying elements, while the process itself requires less energy and lowers environmental impact during hardening. If 10% of traditionally produced steel were replaced with ausferritic steel, greenhouse gas emissions could be reduced by approximately 100,000 tons of CO₂ per year.</p><h3>A Bright Future for Steel</h3><p>In summary, AUSNANITE has the potential to take steel technology to the next level. By combining research and industrial practices with a strong focus on sustainability, the project could pave the way for more robust and long-lasting industrial materials while also strengthening Europe&rsquo;s competitiveness.</p><p><em><strong>More information can be found in this article published in the <a href="~/link/7e1e105d0e0f428cbf0e359f951a315e.aspx" target="_blank" rel="noopener">magazine "Gjuteriet" in 2021</a>.&nbsp;</strong></em></p>https://www.umu.se/en/news/groundbreaking-steel-project-develops-robust-steel-with-lower-co2-emissions_12061920/https://www.umu.se/en/news/high-school-students-get-a-glimpse-into-the-world-of-research_12062491/This spring, nearly 140 high school students from natural science programs at schools in Umeå, Skellefteå, Piteå, Luleå, and Finland will visit Umeå University.

Much of the research on plant cold responses has focused on molecules such as amino acids and sugars that prevent freezing and on the core mechanisms of the temperature response. However, there are many new players that are still disconnected from the big picture.</p><p>Varvara Dikaya&rsquo;s research sheds light on an essential part of this puzzle: RNA splicing, a process that determines which proteins are produced in a plant&rsquo;s cells.</p><p>&ldquo;Splicing acts as a central hub controlling the information flow from DNA to RNA defining which proteins are synthesised from a certain gene,&rdquo; explains Varvara Dikaya, doctoral student in the Department of Plant Physiology at Ume&aring; University and Ume&aring; Plant Science Centre.</p><p>The protein she studied, PORCUPINE, was discovered because plants with a mutation in this gene became particularly cold-sensitive. The name comes from the spiky shape of the shoot tip in these mutants.</p><p>&ldquo;The PORCUPINE mutant appears normal under ambient temperature conditions but cannot develop properly in case of even a mild temperature drop. Already at 16 degrees, the mutant grows shorter roots with increased root hair density and much smaller rosettes than normal. This is very special.&rdquo;</p><p>Varvara Dikaya&rsquo;s research reveals that PORCUPINE is involved in multiple cellular processes. On one hand, colder temperatures increase the amount of PORCUPINE RNA in cells, suggesting that more of the protein is produced. On the other hand, this protein is part of the spliceosome, a molecular complex that modifies RNA before it is translated into proteins.</p><p>Varvara Dikaya and her colleagues also identified several genes regulated by PORCUPINE that play key roles in how plants respond to temperature changes.</p><p>&ldquo;Our findings show the complexity of the cold response in plants. It is important to understand all aspects and identify fundamental mechanisms that could be applied later on in a practical manner. Such knowledge will be essential to create more resilient plants capable of withstanding environmental challenges in the future, even though it is still a long way to go.&rdquo;</p><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="78f30fab-ca4d-4a63-8d07-e6a26a0f3e52" data-contentname="About the doctoral thesis">{}</div><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="1d25738e-0a9f-4d78-8213-405de509bdc4" data-contentname="Contact">{}</div>https://www.umu.se/en/news/how-plants-adapt-to-the-cold_12059463/https://www.umu.se/en/news/dynamic-battle-between-mars-atmosphere-and-the-solar-wind_12058948/Qi Zhang, a doctoral student at the Swedish Institute of Space Physics and Umeå University, explores in her doctoral thesis the interaction between Mars and the stream of charged particles from the sun, the solar wind.

After a period of reflection and internal processes, it became clear that he would take on the responsibility in the beginning of 2025. Fri, 28 Feb 2025 08:47:49 +0100<p>The fact that the choice fell on a political scientist and not a biologist or chemist may, given the subject area CBRNE, seem unexpected but Niklas belives his background in security policy change, geopolitics and Arctic security, led to him being entrusted with the position. The European CBRNE Center has a tradition of initiating, participating in and coordinating EU projects, and within these there is an increasing demand for interdisciplinary perspectives, including Social sciences and Humanities.</p><p>Niklas is also not new to the task of leading a center. He was previously the Director of <a href="~/link/d00e699181f84765bc083ac4784453b2.aspx">the Arctic Center</a> at Ume&aring; University, which gave him valuable experience.</p><p>&rdquo;As a political scientist, I am of course a great believer in good governance, but I also realise that all organisations have their inherent logic. I really hope to combine a sense of order with flexibility at the European CBRNE Center. It is always an exciting journey to try to take on genuinely interdisciplinary environments. At the moment, I'm still learning the ropes here at the center, but the opportunity to work across departments and disciplines is very exciting.&rdquo;</p><h3>Challenges and future perspectives</h3><p>As for the challenges and perspectives&nbsp;on CBRNE issues in Sweden and Europe, Niklas&nbsp;believes&nbsp;the&nbsp;growing&nbsp;availability of information and connections online, along with the rapid development of&nbsp;new&nbsp;technology, is changing current and future threat scenarios.</p><p>&rdquo;We live in complex times, especially with the technological possibilities that exist today to acquire materials and methods for using CBRNE substances in an antagonistic way. Look at the explosions that take place around Sweden almost daily, it makes you wonder what could happen if malicious people or groups gain access and the skills to use other methods or dangerous substances, such as chemical or biological. Another challenge, not only related to CBRNE, is the question of trust in sources of information, will 'people' continue to listen to scientists and authorities, or will they in the future obtain their information mainly through other channels or from other actors? And if so, which ones?&rdquo;</p><p>He also believes that the European CBRNE Centers' contribution and CBRNE issues in general will be of much bigger importance in the years to come.</p><p class="quote-center">I believe that CBRNE issues will become increasingly important in the renewal of our various defense models in the Nordic region. I also see extensive security policy change underway both within and across national borders here in the north, and it would be a shame if Ume&aring; University with its broad range of competence would not take part in that change.</p><h3>Ume&aring;'s role as a CBRNE hotspot</h3><p>What Niklas is looking forward to is building on the centre's strong contacts with authorities, organisations and actors. The steering committee and the collaboration with the centre's partner organisations represent a great potential in further developing collaborations that strengthen Swedish, Nordic and European security.</p><p>&rdquo;Although I have only met the steering committee twice so far, I look forward to continuing the work and together exploring the way forward for the European CBRNE Center.&rdquo;</p><p><strong>How do you see Ume&aring;'s role, position and importance within the CBRNE topics contributing to the work of the European CBRNE Center?</strong></p><p>&rdquo;In the Ume&aring; region, we sometimes talk about the 'CBRNE cluster'. Although it sounds like a strange expression, it stands for something important. In the region, CBRNE expertise is close, between the Swedish Armed Forces, FOI and Ume&aring; University. There are also good contacts with other central actors such as the Swedish Police, the Swedish Fortifications Agency, Ume&aring; Municipality, Region V&auml;sterbotten and the County Administrative Board of V&auml;sterbotten, among others. There is a critical mass here in both research and practice that makes the Ume&aring; region unique.&rdquo;</p><p>And outside work? Then there is another passion that perhaps not everyone knows about.</p><p>&rdquo;Not many people know that I have a soft spot for old cars. And not only that, I own one myself.

These tiny, seed-like structures form when bacteria enter a dormant state to survive unfavorable conditions. They can endure extreme environments, including boiling water, common disinfectants and radiation &mdash; conditions that would kill most bacteria. Their resilience and ability to reactivate when conditions improve make them a major problem in healthcare, agriculture and food production.</p><p>&ldquo;In this interdisciplinary study, we have developed a new, ultra-sensitive method to detect bacterial spores by combining nanoscience and biophysics," says Jonas Segervald, a doctoral student at the Department of Physics, Ume&aring; University. He is one of the researchers behind the new discovery, which was recently published in the scientific journal ACS Sensors.</p><h2 id="info0" data-magellan-target="info0">Early detection crucial in industry</h2><p>The method uses gold nanorods and laser technology to amplify signals from a unique molecule found in spores. This technique, called surface-enhanced Raman spectroscopy (SERS), enables the identification of incredibly small amounts of chemicals &mdash; down to individual molecules. It allows for early detection of bacterial spores even at very low concentrations, which is important in many industries, as preventive measures can be applied at an early stage.</p><p>&ldquo;Spores are highly problematic in hospitals and the food industry, as they can cause recurring contamination by attaching to surfaces and equipment, leading to illness, spoilage and costly cleaning measures,&rdquo; says Dmitry Malyshev, staff scientist at the Department of Physics and co-author of the article.</p><h2 id="info1" data-magellan-target="info1">Health risks in dairy production</h2><p>One promising use of this new method is in the dairy industry, where bacterial spores, particularly from Bacillus species, pose a significant risk. Contamination in dairy production lines can lead to spoilage, product recalls and potential health risks. As milk and dairy products are a central part in Sweden's diet, ensuring a high level of food safety is a top priority. In line with this goal, the researchers successfully detected spores in a contaminated sample of milk, demonstrating the method&rsquo;s potential in improving food safety.</p><p>&ldquo;Our method offers enhanced sensitivity, allowing us to detect much smaller amounts of bacterial spores than previously possible. Although we are still in the early stages, we are actively working to improve this technology into a practical sensor that can be customized for industries at risk of spore contamination," says Jonas Segervald.</p><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="52bdfa36-719b-470b-bc53-4436cd559dd9" data-contentname="About the scientific article">{}</div>https://www.umu.se/en/news/new-ultra-sensitive-method-for-detecting-bacterial-spores_12047886/https://www.umu.se/en/news/the-internship-in-germany-was-an-eye-opener_12043405/Doing an internship abroad is a chance to both broaden your skills and gain new perspectives on working methods and cultures.

Our new chemical tool with light switches will make it easier to control processes in the cell and study how cells function in real time. We can also determine where we make such regulation with a resolution of micrometres within a cell or tissue&rdquo;, says Yaowen Wu, professor at the Department of Chemistry and SciLifeLab Group leader at Ume&aring; University.</p><p>The intricate choreography of what happens in a cell is based on the precise distribution and interaction of proteins over time and space. Controlling protein or gene function is a cornerstone of modern biological research. However, traditional genetic techniques such as CRISPR-Cas9 often operate on a longer time scale, which risks causing cells to adapt. In addition, the techniques lack the spatial and temporal precision required to study highly dynamic cellular processes.</p><p>To address these challenges, so-called chemo-optogenetic systems have emerged as powerful tools. These systems combine chemical molecules, optics, and genetically modified proteins to precisely control protein activities at specific locations in cells using light-sensitive small molecules. Professor Yaowen Wu&rsquo;s lab is at the forefront of developing chemo-optogenetic systems.</p><p>Previously, Yaowen Wu&rsquo;s lab introduced systems based on a type of molecular glue. These work by bringing two proteins close together to change the localization or activity of a protein. The molecular glues are activated or deactivated by light by removing or cleaving a light-sensitive group. Although these tools represented significant advances, they had limitations in their use and insufficient photo- and chemical stability.</p><p>In two new publications selected as hot papers in the journal Angewandte Chemie International Edition and Chemistry &ndash; A European Journal, researchers in the Wu lab have developed next-generation chemo-optogenetic tools based on photoswitchable molecular glues. These improve on previous systems and overcome limitations. Through the modified molecular design, these molecular glues can be turned &ldquo;on&rdquo; or &ldquo;off&rdquo; like a light switch using light of specific wavelengths, allowing for multiple activation cycles where the two different states either promote or inhibit protein function.</p><p>&rdquo; The new modular design enables enormous versatility of the system with adaptable properties and more stability&rdquo;, says Jun Zhang, staff scientist at the Department of Chemistry at Ume&aring; University.</p><p>&ldquo;In our experiments, we were able to demonstrate precise control over several processes in the cell, including protein function and localization, organelle positioning and protein levels&rdquo;, says Laura Herzog, postdoctoral fellow at the Department of Chemistry at Ume&aring; University.</p><div class="mediaflowwrapper bildlink"><div class="bildImage"><picture><source srcset="/contentassets/5694cbbb42eb464a8c9f0837866b232d/fotomask_final3.jpg?format=webp&amp;mode=crop&amp;width=640 640w, /contentassets/5694cbbb42eb464a8c9f0837866b232d/fotomask_final3.jpg?format=webp&amp;mode=crop&amp;width=854 854w, /contentassets/5694cbbb42eb464a8c9f0837866b232d/fotomask_final3.jpg?format=webp&amp;mode=crop&amp;width=1280 1280w" type="image/webp" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"><source srcset="/contentassets/5694cbbb42eb464a8c9f0837866b232d/fotomask_final3.jpg?mode=crop&amp;width=640 640w, /contentassets/5694cbbb42eb464a8c9f0837866b232d/fotomask_final3.jpg?mode=crop&amp;width=854 854w, /contentassets/5694cbbb42eb464a8c9f0837866b232d/fotomask_final3.jpg?mode=crop&amp;width=1280 1280w" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"></picture></div><div class="bildText"><p>The activity of a luminescent protein can be tuned by light using the photoswitchable molecular glues developed in these studies.

Among other things, he is responsible for the Classical Mechanics course that about a hundred MSc engineering students take every year. When he was awarded the faculty's pedagogical prize in 2024, his valued work with international students was also highlighted.</p><p>Since 2014, he has been international contact person at the Department of Physics. There, he has worked on everything from signing exchange agreements with universities in other countries to guiding incoming students.</p><p>&ldquo;You are a bit vulnerable when you come to a foreign country. Many have travelled halfway around the world and don't understand the language. I usually think about what I would have wanted help with if it were me.&rdquo;</p><h3>Long exams a shock</h3><p>Students often come to him for support in matching which courses they should take, especially if they are courses given at several different institutions. Jens also gets to explain how the study system in Sweden works.</p><p class="quote-left">You are a bit vulnerable when you come to a foreign country</p><p>&ldquo;Many are quite shocked that we can have six-hour exams. They may be used to two hours, but then you are in a hurry and can't get all the assignments done.&rdquo;</p><p>&ldquo;I also usually talk a little about Swedish culture when I meet them and explain that it is okay to address your teachers by their first names. Then the International Office does a great job with Orientation Day and other activities! It has made the care of international students much better.&rdquo;</p><p><em>What makes working with international students fun, in your opinion?</em></p><p>&ldquo;I get an insight into how they study in other countries, what the differences are compared to here and how they view it. And many students are very nice and fun to talk to!&rdquo;</p><h3>Fewer after the pandemic</h3><p>Before the pandemic, the Physics Department received around 70 exchange students each year. Currently, 40-50 come per year. Significantly fewer Swedish students take the chance to study abroad.</p><p>&ldquo;It&rsquo;s about two to four students. Things were turning around, one year we had more than that going to Hong Kong and South Korea. The following year I had nominated 16 who wanted to go, but then the riots in Hong Kong came and then the pandemic.&rdquo;</p><p><em>How can we get more domestic students to choose to study abroad?</em></p><p>&ldquo;I think what has the most effect is that those who have gone abroad can come and tell others here about their experiences.&rdquo;</p><p>Most of the foreign students that the Physics Department receives come from Germany, France, Turkey, Spain, Portugal and China.</p><p>&ldquo;We offer quite a few courses at advanced level and the exchange students allow us to maintain a wider range of courses than we otherwise could.&rdquo;</p><h3>Increased independence</h3><p><em>What do you see as the biggest benefits for students participating in exchange studies?</em></p><p>&ldquo;That they feel more independent, that they can go out into the world and feel that they can handle it. For some who come here from other countries, when they move away from home to study, they live in a college, have food served and their room cleaned. Here they have to manage everything themselves. Another big advantage, which the students themselves may not always think about, is that they get the opportunity to study courses that are not available at their home university.&rdquo;</p><p><em>Have you been abroad as an exchange student yourself?</em></p><p>&ldquo;No, but after my dissertation I was a post doc in Strasbourg in France. I didn't know the French language and took evening classes and such, but it was still tough and I was quite isolated. But, of course, more research work was done instead.&rdquo;</p><p>Now Jens will have to take a bigger grip on the internationalization work than at his own department. Step one is to familiarize himself with all the agreements that exist and continue the work that his predecessor Konrad Abramowicz started.</p><p>&ldquo;He started with meetings for all departments' international contact persons and to have a joint call for applications for outgoing students. This has simplified a lot, but I think there are more opportunities for collaboration and that we may be able to encourage more departments to have similar agreements as we have for double degrees.&rdquo;</p><h3>Double degrees bring advantages</h3><p>The Physics Department has agreements with two Chinese universities, Shenzhen and South West University, which give students the opportunity to obtain a bachelor's degree from two countries at the same time. The students study three years at their home university and one year in Ume&aring;, including their degree project.</p><p>&ldquo;They can count their studies in China towards their degree from here and vice versa. It shows more clearly that they have studied in two places. It also makes it easier if they want to study further in Europe, then they have a Swedish bachelor's degree. We also drill them quite hard, they have several advanced courses in their bachelor's degree, which gives a stronger bachelor's degree. That is also an advantage for them.&rdquo;</p><p>A similar model could be viable at more departments, as well as inspire more Swedish students to obtain a double degree, Jens Zamanian believes.</p><p>&ldquo;When we had a visit from Shenzhen, Konrad, Markus &Aring;dahl and Victor Falgas-Ravry from the mathematics department were there and met them. If mathematics is interested, I think more people might be.&rdquo;</p><p>&ldquo;I also know that sometimes several departments have exchange agreements with the same university. There may be advantages in combining these into a faculty agreement.&rdquo;</p><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="3d311aac-589d-4bc1-a0cc-06f5073c831b" data-contentname="ABOUT Jens Zamanian">{}</div>https://www.umu.se/en/news/jens-wants-more-students-to-study-abroad-and-get-a-double-degree_12033582/https://www.umu.se/en/news/permafrost-thaw-threatens-up-to-three-million-people-in-the-arctic_12032685/Permafrost thaw poses multiple risks to local Arctic communities, their livelihoods, infrastructure and environment.

Here, under the ice-covered surface of Rossfjordsvatnet, we explore how toxic compounds are formed in oxygen-free environments and what clues these waters can provide about our future in an increasingly warmer world.Wed, 08 Jan 2025 13:54:50 +0100<div class="mediaflowwrapper bildlink"><div class="bildImage"><picture><source srcset="/contentassets/4577ef6d4e2a437f9ec340a34d4bd7de/fjords_frontiers_documentary3.jpg?format=webp&amp;mode=crop&amp;width=640 640w, /contentassets/4577ef6d4e2a437f9ec340a34d4bd7de/fjords_frontiers_documentary3.jpg?format=webp&amp;mode=crop&amp;width=854 854w, /contentassets/4577ef6d4e2a437f9ec340a34d4bd7de/fjords_frontiers_documentary3.jpg?format=webp&amp;mode=crop&amp;width=1280 1280w" type="image/webp" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"><source srcset="/contentassets/4577ef6d4e2a437f9ec340a34d4bd7de/fjords_frontiers_documentary3.jpg?mode=crop&amp;width=640 640w, /contentassets/4577ef6d4e2a437f9ec340a34d4bd7de/fjords_frontiers_documentary3.jpg?mode=crop&amp;width=854 854w, /contentassets/4577ef6d4e2a437f9ec340a34d4bd7de/fjords_frontiers_documentary3.jpg?mode=crop&amp;width=1280 1280w" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"></picture></div><div class="bildText"><p>Photo from the film Fjords Frontiers: Digging into the future of climate change</p><span class="bildPhotografer"><span class="photo">Image</span>Eric Capo</span></div></div><p>A sharp breeze sweeps over Rossfjordsvatnet in northern Norway. On the surface, the fjord is still and seemingly untouched, but beneath its surface hides a history that stretches back tens of thousands of years &ndash; and which may provide clues to what our future will look like. Right here, researchers Eric Capo and Erik Bj&ouml;rn, both at Ume&aring; University, have dug deep into the fjord's sediments and water masses to investigate one of climate research's most burning topics: how toxic compounds such as methylmercury are formed and spread in oxygen-free ecosystems.</p><p>Their work is not only documented in scientific articles but also in films. The documentary Fjords Frontiers: Digging into the Future of Climate Change premiered on December 12 at Curiosum, and the researchers are looking forward to sharing their research with a wider audience.</p><h3>Reading the fjord as an archive</h3><p>At the heart of their research is the question of how oxygen deprivation in aquatic ecosystems, which is exacerbated by climate change and eutrophication, affects the formation of methylmercury. This extremely toxic compound can be produced by microorganisms in oxygen-free environments and accumulate in fish, which can ultimately pose a health risk to humans.</p><p>"We see that oxygen depletion in coastal zones and oceans increases with global warming, and this can lead to an increase in methylmercury production. We want to understand the key processes that govern this, in order to be able to predict which areas are most vulnerable in the future," says Erik Bj&ouml;rn, professor at the Department of Chemistry.</p><p class="quote-left">We wanted to give a picture of what it means to be a researcher and work with climate change. At the same time, we hope to inspire young people to become researchers and get involved in the major environmental challenges</p><p>By analysing the sediment archive in Rossfjordsvatnet and studying the microbial diversity in the fjord, the research team has gained new knowledge about how these processes work. An early finding is that methylmercury levels increase sharply in oxygen-free water &ndash; a result that now forms the basis for further analyses.</p><p>"It was in line with our expectations, but the really important thing is to find out whether this is controlled by the chemical properties of the mercury or by the biology of the microorganisms," says Eric Capo, Associate Senior Lecturer at the Department of Ecology and Environmental Sciences.</p><h3>From lab to film screen</h3><p>Documenting the research in film format was a new approach for Eric and Erik. The idea was born out of a desire to show people how research is done and what issues drive science forward.</p><p>"We wanted to give a picture of what it means to be a researcher and work with climate change. At the same time, we hope to inspire young people to become researchers and get involved in the major environmental challenges," says Eric Capo.</p><p>The documentary gives viewers an insight into everything from on-site sampling to advanced analyses in the laboratory. By combining beautiful nature images with educational explanations, the researchers hope that the film will be both engaging and educational.</p><h3>Premiere nerve and public issues</h3><p>Premiering the film felt both nervous and exciting, according to Eric and Erik. Their hope is that the film will lead to conversation and reflection on climate issues. They look forward to meeting viewers' questions, which often challenge them to think outside the box.</p><p>"Discussions with the public can really enrich research. Questions from people outside academia can provide new perspectives that we ourselves have not thought of," says Erik Bj&ouml;rn.</p><p>Although the film is now finished, the research continues. The project started in September 2023 and will run for at least another 2&ndash;3 years. During that time, the team hopes to add more pieces to the puzzle of how methylmercury is formed and which ecosystems are most vulnerable.</p><p>"Our hope is that the results can be used to protect marine ecosystems and reduce risks to human health," says Eric Capo.</p><div data-classid="36f4349b-8093-492b-b616-05d8964e4c89" data-contentguid="f66b6839-93f5-45d8-8f6e-54c404650ab7" data-contentname="Documentary film">{}</div>https://www.umu.se/en/news/new-documentary-on-the-challenges-of-climate-research_12017646/https://www.umu.se/en/news/new-members-from-umea-university-in-the-swedish-research-councils-scientific-councils_12021283/Fredrik Almqvist, Sofia Lundberg, and Jörgen Johansson from Umeå University have been appointed as new members of the Swedish Research Council's three scientific councils.

But while Christmas trees bring warmth and joy into our lives, they endure some of the harshest conditions on Earth in their natural habitats. Most people take it for granted that they maintain their needles lush and green in freezing winters and blinding sunlight in the boreal forests but now scientists can unwrap the science behind conifers’ winter survival.

Yet, there are differences and scientists are gradually understanding more about both the differences and commonalities.</p><p>Conifers have extraordinary winter survival strategies, some of them were not understood until recently. Scientists from Ume&aring; University have, together with colleagues, summarized recent breakthroughs in an article published in Trends in Plant Science.</p><h2 id="info0" data-magellan-target="info0">Dissipates extra energy</h2><p>One of the two main findings, both of which this group of researchers have contributed to, is that conifers change the structure of their thylakoid membranes &ndash; where photosynthesis takes place &ndash; making Photosystem I (PSI) and Photosystem II (PSII), which otherwise by large remain separated, come in winter closer to each other and work together in a special way named spill-over.</p><p>&ldquo;This helps them to safely dissipate extra energy and avoid damage from too much sunlight in the cold,&rdquo; says Stefan Jansson, Professor at Ume&aring; Plant Science Centre at Ume&aring; University.</p><p>Others have previously, without understanding the mechanism, named the process &lsquo;Sustained Quenching&rsquo; as it could put photosynthesis into a lock down mode for days.</p><div class="mediaflowwrapper bildlink"><div class="bildImage"></div><div class="bildText"><p>The findings could be used for breeding conifers that are resilient to extreme weather conditions.</p><span class="bildPhotografer"><span class="photo">Image</span>Stefan Jansson and Pushan Bag</span></div></div><p>The second strategy, operating in parallel to spillover, is that conifers use special routes for moving the electrons in photosynthesis. These paths, known as alternative electron flow, involve flavodiiron proteins and help keep the photosynthesis process balanced. This also prevents the system from becoming overloaded when there's too much light and freezing temperatures.</p><h2 id="info1" data-magellan-target="info1">Conifers are the dominant species</h2><p>In addition, the photosynthetic apparatus of conifers differs from that of flowering plants (angiosperms) in a few other ways. They lack, for example, some so-called light-harvesting proteins found in other plants.</p><p>&ldquo;All together this can explain why conifers are the dominant species in boreal forests, thriving where few others can, perhaps at the expense of advantages during less challenging conditions; few conifers, if any, grow where water, nutrients and temperature conditions are all favourable&rdquo; says Pushan Bag, lead author who during his doctoral studies at Ume&aring; Plant Science Centre studied these phenomena.</p><p>Understanding these mechanisms may also aid conservation and help predict forest responses to climate change and may in the longer perspective inform strategies for breeding crops that are resilient to extreme weather conditions.</p><p>Co-author Alexander Ivanov adds:</p><p>&rdquo;This paper highlights the intricate adaptations of conifers to extreme winter conditions.

During his years at the center, he has become an important and unifying figure within the European CBRNE community.Tue, 07 Jan 2025 15:05:06 +0100<p>Curiosity about the the European CBRNE center&rsquo;s work led Per-Erik Johansson to accept an invitation for coffee from his predecessor, <a href="~/link/8d8b38b5d26149e6ba6b486ccca5b150.aspx">Dzenan Sahovic</a>. During their chat, Per-Erik learned that the position of Director for the European CBRNE Center was about to be announced. Having previously been involved in the center&rsquo;s founding under &Aring;ke Sellstr&ouml;m&rsquo;s leadership, Per-Erik saw an opportunity to continue the important work of his predecessors while keeping his home base in Ume&aring;, despite the job&rsquo;s European focus.</p><p>Per-Erik applied for the position and, in July 2015, two staff members and the center&rsquo;s steering committee welcomed him. In the early years, the focus was on securing research funding and building connections with relevant networks and stakeholders. After successful applications and networking efforts, the center coordinated and participated in several projects and initiatives at both national and international levels. As the workload grew, the center expanded its team with two additional staff members.</p><p>Since 2015, exciting projects such as <a href="~/link/f7f9868fd0ce4457ac1c12ae596b945e.aspx">Safety &amp; Security Test Arena</a>, <a href="~/link/8f8982a705e4405da37b855a41bf564f.aspx">CELECTIVE</a>, and <a href="~/link/70faf26d0c4547ddbd1250934f8d5b8d.aspx">MELODY</a> have been initiated and completed. Per-Erik has plenty of stories and anecdotes about great ideas and results achieved, as well as setbacks and successes, which he shares with enthusiasm without forgetting a single name of those involved. One memory he holds dear is how the idea for the PROACTIVE project emerged during a reflective conversation after an exercise that had come to a halt when a guide dog (belonging to a blind participant) left first responders scratching their heads in confusion.</p><p>"During the exercise, the first responders didn&rsquo;t know the best course of action to take with the dog, and it sparked thoughts about what other elements need to be considered when managing large, diverse groups, and how to care for people &mdash; and even animals &mdash; that previously haven&rsquo;t been included in exercises. This became the starting point for what later became PROACTIVE, a groundbreaking project in CBRNE research with a focus on groups that may be considered as being particularly vulnerable during CBRNE incidents."</p><p>When asked about the most challenging aspect of his role, Per-Erik responds:</p><p>"It&rsquo;s probably the slowness I perceive when it comes to applying innovations and new methods.

"The best chance is when it is dark and clear in the evenings," he says.Mon, 14 Apr 2025 13:51:35 +0200<p>They are nature&rsquo;s fireworks with bright colours dancing across the sky. For both young and old, seeing the Northern Lights is a powerful experience, and many people travel long distances to Northern Europe just to see them. The light we see consists of small particles, primarily electrons, thrown off from the Sun and crashing into atoms in Earth&rsquo;s upper atmosphere at high speeds.</p><p>&ldquo;The phenomenon can be compared with what happens in a fluorescent tube or a neon sign. When the different shells around the atoms are hit by these electrons, light is emitted,&rdquo; explains Patrik Norqvist, doctor of space physics and associate professor in physics at Ume&aring; University.</p><div class="mediaflowwrapper bildlink"><div class="bildImage"><picture><source srcset="/contentassets/edd02e8fad134a13bf30431c8ad9700a/northen_lights_at_loberget_fredrik_larsson_visit_umea3.jpg?format=webp&amp;mode=crop&amp;width=640 640w, /contentassets/edd02e8fad134a13bf30431c8ad9700a/northen_lights_at_loberget_fredrik_larsson_visit_umea3.jpg?format=webp&amp;mode=crop&amp;width=854 854w, /contentassets/edd02e8fad134a13bf30431c8ad9700a/northen_lights_at_loberget_fredrik_larsson_visit_umea3.jpg?format=webp&amp;mode=crop&amp;width=1280 1280w" type="image/webp" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"><source srcset="/contentassets/edd02e8fad134a13bf30431c8ad9700a/northen_lights_at_loberget_fredrik_larsson_visit_umea3.jpg?mode=crop&amp;width=640 640w, /contentassets/edd02e8fad134a13bf30431c8ad9700a/northen_lights_at_loberget_fredrik_larsson_visit_umea3.jpg?mode=crop&amp;width=854 854w, /contentassets/edd02e8fad134a13bf30431c8ad9700a/northen_lights_at_loberget_fredrik_larsson_visit_umea3.jpg?mode=crop&amp;width=1280 1280w" sizes="(max-width: 639px) 640px, (max-width: 854px) 854px, 1280px"></picture></div><div class="bildText"><p>Northern Lights over Loberget, Botsmark.

Some atoms, like oxygen, can emit more than one colour.

Northern Sweden is within the so called auroral zone in the northern hemisphere, allowing ample opportunities to see the Northern Lights.</p><p>&ldquo;If the speed of the electrons is extremely high, the auroral zone can be pushed down into southern Sweden or in extreme cases into continental Europe. But reaching south of Sweden requires very high speeds. So Stockholm has less Northern Lights than Ume&aring; and Ume&aring; has less than Kiruna.

This is when the sun's magnetic field changes direction, which, in simple terms, causes a lot of fuss and bother, with more sunspots and turbulent magnetic fields. As a result, more solar storms occur, which can affect everyday life on Earth through, for example, power cuts, air traffic disruptions or even the Northern Lights.</p><p>One such period occurred during the winter of 2024/2025.</p><p>&ldquo;This ebbs and flows with a periodicity that we have been able to follow for hundreds of years and seems to be very stable in its 11-year cycle.

Of course, it is darker longer in the winter.&rdquo;</p><p>There are now apps and websites that can forecast when Northern Lights might be visible by combining estimates of solar activity with the risk of cloud cover. These are dependable in the same way that weather apps show us the best estimate for weather conditions, explains Patrik.</p><p>An interesting aspect is that cameras tend to capture Northern Lights better than the human eye.</p><p>&ldquo;It&rsquo;s odd that Northern Lights are often better in pictures than when seeing them in real life.
