It is 400 years since Johan Skytte founded a professorship in eloquence and political science. His intention was to strengthen the state administration that Sweden needed to maintain its position as a European great power. The Johan Skytte Professorship is the oldest active chair in political science in the world. To mark the 400th anniversary, lecture and panel debate will be held 1 October.
Researchers from Uppsala University and elsewhere have been studying the effect of rising temperatures on the lifespan of pollinating fig wasps. The findings show that the wasps lived much shorter lives at high temperatures, which would make it difficult for them to travel the long distances between the trees they pollinate.
There are strong links between bacteria living in the gut and the levels of small molecules in the blood known as metabolites. Such is the finding of a new study (Uppsala University/Lund University). The study is based on analyses of both fecal and blood samples from 8,583 participants in the Swedish CArdioPulmonary bioImage Study (SCAPIS).
Sverker C Jagers, Professor of Political Science and Director of the Centre for Collective Action Research at the University of Gothenburg, will hold Uppsala University's fifth Zennström Visiting Professorship in Climate Change Leadership. The ten-year visiting professorship, through which a new professor is invited every year or every other year, is funded by an earlier donation to Uppsala Univ
In a large international study, researchers at Uppsala University have identified DNA regions that are associated with physical activity or leisure screen time. The findings confirm that physical activity is beneficial for health and suggest that a more sedentary lifestyle can be explained by how muscles respond to exercise.
In the condition known as cerebral cavernoma, lesions arise in a cluster of blood vessels in the brain. In a new study from Uppsala University, researchers show that blood coagulation and blood clot formation are very relevant for the disease and that antithrombotic therapy may be beneficial for cavernoma patients.
An international team led by Uppsala University researchers has uncovered that eukaryotes (organisms with a cellular nucleus) have made hundreds of big leaps from sea to soil and freshwater habitats, and vice versa, during their evolution. The results, published in Nature Ecology and Evolution, also provide insights into what the habitats of our ancient microbial ancestors looked like.
Researchers from several universities have, by studying helical molecules in the body such as DNA, received clues as to how energy production in fuel cells can be made more efficient without admixture of carbon dioxide and heavy metals. The new research shows how the helical molecules, found naturally in all oxygen-dependent life, catalyses energy production in the cells.
Loss of the Y chromosome in blood cells of men is associated with disease and mortality, but no clear causal relationship has previously been identified. Now, researchers from Uppsala University show in the journal Science that loss of the Y chromosome in white blood cells causes development of fibrosis in the heart, impaired heart function and death from cardiovascular diseases in men.
In a study an international team of researchers have identified 28 gene regions that have been particularly important in the evolution of Darwin’s finches. These genetic variants do not represent recent mutations but constitute ancestral genetic variation that has accumulated over time as different species of Darwin’s finches have evolved with striking differences in beak morphology.
Impaired hearing affects billions of people, but crocodiles, who live almost as long and can surpass 70 years of age, have good hearing throughout their lives. One reason is because can create new hair cells, and a research group from Uppsala University is now on the path to finding out why. Hopefully, knowledge from the world of crocodiles will be able to help people with impaired hearing.
Municipalities can use their local housing policy to influence the intake of refugees and the extent to which refugees are able to settle in the municipality in the long term. While certain municipalities offer refugees permanent housing contracts, others only provide temporary contracts that make it difficult for individuals to stay and establish themselves in the municipality.
The recent Fagradalsfjall eruption in the southwest of Iceland has enthralled the whole world, including nature lovers and scientists alike. The eruption was especially important as it provided geologists with a unique opportunity to study magmas that were accumulated in a deep crustal magma reservoir but ultimately derived from the Earth’s mantle (below 20 km).
Oral contraceptives and hormone therapy at menopause increase the risk of stroke. The increased risk is greatest during the first year of treatment and then declines. The study, which is now published in Stroke, is based on data from over a quarter of a million women from the UK Biobank database.
New data from the Uppsala Conflict Data Program (UCDP) at Uppsala University show that at least 119,000 people died in organised violence in 2021. This is an increase of 46 per cent compared to the previous year, and the highest number since 2015.
Historic virus infections can be traced in vertebrate genomes. For millions of years, these genomes have been repositories for retroviruses that incorporated their code into germline cells and were inherited as endogenous retroviruses (ERVs). Researchers from Uppsala University now provide new findings about retroviral establishment in the koala genome. The findings are being published in PNAS.
A new study combining archaeological, historical and bioarchaeological data provides new insights into the early Islamic period in modern-day Syria. The research team was planning to focus on a much older time period but came across what they believe to be remains of early Muslims in the Syrian countryside.
Researchers from the Zoonosis Science Center at Uppsala University have identified a new coronavirus. Their study of approximately 260 bank voles caught around Grimsö, Örebro County, shows that the virus is well established in Sweden’s red-backed voles. The finding has been published in the journal Viruses.
A gene variant in the natural immune system influences the risk for blood clots in the lungs of severely ill COVID-19 patients. This has been documented in a new study by researchers at Uppsala University and Karolinska Institutet that has now been published in Nature Immunology.
Although some rare genetic variants can increase the risk of disease markedly for a few individuals, the genetic contribution to common diseases is mostly due to a combination of many common genetic variants with small effects. This is shown in a comprehensive study by researchers at Uppsala University and SciLifeLab, published in the journal Nature Communications.
