  • One single rule helps explain life from ocean depths to open savannas

    A new study published in Nature Ecology & Evolution has found a simple rule that seems to govern how life is organised on Earth. The researchers believe this rule helps explain why species are spread the way they are across the planet. The discovery will help to understand life on Earth – including how ecosystems respond to global environmental changes.

  • Catalytic system turns biomass waste to renewable chemical stock

    Researchers at Umeå University in Sweden, in collaboration with scientists from Finland, Vietnam, India, and Italy, have developed a catalytic system to convert lignin structures into highly valuable chemicals. This innovative technology offers promising solutions to pressing environmental and energy challenges.

  • Binding to surface sugars enhances Omicron's cell attachment

    A new study from Umeå University reveals how SARS-CoV-2 variants, including Omicron, have adapted to bind more effectively to human pulmonary cells. The stronger binding is explained by an increased and optimised interaction between the virus and heparan sulfate, a long sugar molecule on the cell surface.

  • New knowledge about cell division with data-driven techniques

    Research from Umeå University paves the way for a quantitative data analysis method to study the cell division process in individual cells. The improved resolution will promote advanced cell analysis in the human body, especially in cases of incorrect cell division such as in the context of cancer.

  • New light-tuned chemical tools control processes in living cells

    A research group at Umeå University has developed new advanced light-controlled tools that enable precise control of proteins in real time in living cells. This groundbreaking research opens doors to new methods for studying complex processes in cells and could pave the way for significant advances in medicine and synthetic biology.

  • The science behind Christmas trees: How conifers brave winter's worst

    As the festive season approaches, evergreen conifers adorn homes worldwide. 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 but now scientists can unwrap the science behind conifers’ winter survival.

  • Nanoplastics can impair the effect of antibiotics

    Minuscule particles of plastic are not only bad for the environment. A study led from Umeå University, Sweden, has shown that the so-called nanoplastics which enter the body can impair the effect of antibiotic treatment. The results also indicate that the nanoplastics may lead to the development of antibiotic resistance.

  • Mixed forests reduce the risk of forest damage in a warmer climate

    Forests with few tree species pose considerably higher risk of being damaged and especially vulnerable is the introduced lodgepole pine. This is shown in a new study by researchers from Umeå University and the Swedish University of Agricultural Science in Uppsala. The results can be useful for preventing forest damages and financial losses related to the forest industry.

  • Computational physics to make AI-controlled heavy machinery safer

    When heavy machinery is to become robots with autonomous capabilities, safety is at highest priority. In a new EU project, researchers and industry collaborate to develop reliable and efficient AI-driven machines that minimize the risk of harming people or the environment.

  • Researchers aim to create biodegradable plastic – from algae

    The Waste2Plastic project at Umeå University has received SEK 15 million from the Swedish Energy Agency and its industrial partners to produce biodegradable plastics, PHA, using microalgae. The algae are grown in wastewater in Umeå and convert carbon dioxide from flue gases into biomass.

  • Altered blood markers detected in individuals with periodontitis

    Individuals with periodontitis have altered concentrations of various proteins in their blood, according to a new study from Umeå University, Sweden. These findings pave the way for research into biomarkers for periodontitis and the underlying causes of the disease. Severe periodontitis affects about one in ten Swedes and, in addition to tooth loss, can also be linked to other diseases.

  • Changes in the brain detected in severe PMS

    It is possible to see changes in both brain function and structure in women with premenstrual dysphoric disorder, which is a severe form of PMS. This is shown in a new doctoral thesis at Umeå University, Sweden. The changes in the brain can persist even after the premenstrual period.

  • Possible explanation for link between diabetes and Alzheimer's

    People with type 2 diabetes are at increased risk of Alzheimer's disease and other cognitive problems. A new study led by Umeå University, Sweden, shows that the reason may be that people with type 2 diabetes have more difficulty getting rid of a protein that may cause the disease.

  • 36’000 tea bags explain global decomposition pattern on new web

    Co-developed by Umeå University, a method to measure the decay of plant material with the help of simple tea bags has become the standard in scientific research. Researcher Judith Sarneel, Umeå University, Sweden, has now collected data from over 36’000 individual tea bags worldwide and has revealed global patterns of decomposition in the journal Ecology Letters and on a newly established website.

  • Future diet – plant-based fermented foods on the plate

    The first consumer study focusing on plant-based fermentation. Researchers at Umeå University have conducted the first consumer study focusing on plant-based fermentation and its role in the necessary dietary transition to achieve European health and sustainability goals.

  • Degradation of cell wall key in the spread of resistance

    A study at Umeå University, Sweden, provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.

  • The world's first AI-controlled forest machine trained on supercomputor

    For the first time, scientists have succeeded in creating a self-driving forest machine controlled by artificial intelligence. In a research study at Umeå University, Sweden, an AI system was developed that can operate the 16-ton machine without human intervention. The study has been carried out in collaboration with Skogforsk and Algoryx Simulation.

  • Using AI and math can prepare for new infections in changing climate

    It is possible to forecast how different infectious diseases will spread across Europe in relation to global warming. This is made by using artificial intelligence and mathematical modelling of changing travel patterns and disease effects. In this way, it will be possible to take countermeasures and build up preparedness. This is shown in a new doctoral thesis at Umeå University, Sweden.

  • Prejudices favour neither students nor the IT industry

    The world urgently needs skilled software developers with a holistic perspective. Yet there are many 'he' and few 'she' and 'they' in the industry. “The prejudiced view of computer scientists as a shy white man sitting alone coding in a basement, does not benefit you as a student, the IT industry or society," says Anna Jonsson, responsible for the Civil Engineering Programme in Computing Science.
