  • 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.

  • 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.

    10 million to project for sustainable shrimp and fish production

    The Swedish Agricultural Agency has granted SEK 10 million for a project on sustainable food production, led by Olivier Keech, Department of Plant Physiology at Umeå University and Umeå Plant Science Centre. The project aims to establish and optimize sustainable production of shrimp and fish in a circular aquaculture system.

  • Changes in the brain detected in severe PMS

    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.

    Details of photosynthesis revealed with record-breaking images

    By generating extremely high-resolution images in a cryo-electron microscope, researchers at Umeå University have revealed the positions of hydrogen atoms and water molecules in photosynthesis. This breakthrough provides a new avenue towards uncovering how water is split – a process crucial for life on Earth as well as for scaling up renewable energy systems.

  • Lung cancer does not decrease in line with reduced smoking

    Lung cancer does not decrease in line with reduced smoking

    Despite the fact that the number of people who smoke has decreased very sharply in Sweden, the number of cases of lung cancer in the population is not decreasing as much as expected. Among women lung cancer has in fact increased. This is shown in a new study at Umeå University, Sweden. The study means that the view of how long smoking affects health may change.

  • Increased risk of heart rhythm disruption after COVID-19

    Increased risk of heart rhythm disruption after COVID-19

    Individuals infected with COVID-19 are also at an increased risk of suffering from heart rhythm disturbances, such as atrial fibrillation. This is shown in a new study at Umeå University, Sweden, which is one of the largest studies of its kind in the world.

    Birch leaves as raw material for the production of organic semiconductors

    Today, petrochemical compounds and rare metals are usually used to produce semiconductors for optoelectronics, such as organic LEDs for super-thin TV and mobile phone screens. By pressure-cooking birch leaves picked on the Umeå University campus, the scientists behind this study produced carbon particles that can be used as raw material for organic semiconductors.

    Beyond recycling: new role for autophagy protein in membrane repair discovered

    Maintaining the structure of intracellular membranes is essential for preserving normal cellular function. New research by a team of biochemists at Umeå University identifies a strategy employed by cells to detect and repair membranes that have been damaged by chemical or bacterial stress.

    Arctic research grows and strengthens international cooperation

    A new report by UArctic highlights the growing diversity and number of research activities across the Arctic. UArctic is a collaboration between academic institutions and other organizations with an interest in northern regions. The report demonstrates a high degree of international cooperation and presents Arctic research trends.

    World’s longest lichen declines in a national park

    A unique long-term study performed by researchers at Umeå University shows that the pendent lichen Usnea longissima decreases with 42 percent over 37 years in Skuleskogen National Park, located in High Coast UNESCO World Heritage site. The study has been published in the journal Forest Ecology and Management.

  • Collaboration between the Centre for Sustainable Cement and Quicklime Production at Umeå University, Nordkalk AB and the Swedish Energy Agency has resulted in a decrease in carbon dioxide emissions from lime kilns in Sweden. Photo: Nordkalk AB

    Project has reduced CO2 emissions from Swedish lime kilns

    Carbon dioxide emissions from lime kilns in Sweden have been reduced by more than 36 000 tons per year. This has been achieved through a collaboration between the Centre for Sustainable Cement and Quicklime Production at Umeå University, Nordkalk AB and the Swedish Energy Agency.

    Neutrons provide unique insight into programmed cell death

    Using neutron reflectometry, researchers at the Department of Chemistry, Umeå University, provide new atomic-level understanding of how Bax, a protein that helps remove damaged cells in the body, works. The results of the study, conducted in collaboration with the ESS research facilities in Lund and ISIS in the UK, are published in the journal Science Advances.

    New transporter for recycling of bacterial cell wall found

    A transporter which some bacteria use to recycle fragments of their cell wall has been discovered by researchers at Umeå university, Sweden. They found that the transporter controls resistance to certain kinds of cell-wall targeting antibiotics.
