Scandinavian wolves carry many harmful mutations
14 december 2022
In a new scientific study, researchers at Uppsala University have shown that Scandinavian wolves carry around 100,000 harmful mutations in their genome. As long as the harmful mutations can be compensated by a healthy genetic variant, this does not need to pose a problem. However, as there has been a high level of inbreeding in the wolf population, the occurrence of double harmful variants has increased with each generation.
Y chromosome loss may be linked to men's increased risk of severe COVID-19
14 december 2022
Men are at an increased risk of a severe bout of COVID-19 compared to women. Researchers at Uppsala University have now shown that this may be due to loss of the Y chromosome in part of their white blood cells. The findings could eventually be used to assess the risk of developing severe COVID-19 and perhaps to improve treatment.
Atopic dermatitis in dogs linked to certain parts of the genome
09 december 2022
Using new gene mapping methods, researchers have found connections between atopic dermatitis (eczema) in dogs and several regions of the genome. Some of the genes identified coincide with genes linked to similar problems in humans. The filaggrin gene region, for example, which is regarded as the most powerful risk factor for atopic eczema in humans, has now also been linked to this disease in Labrador retrievers.
DNA sequence enhances understanding origins of jaws
25 november 2022
Researchers at Uppsala University have discovered and characterised a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the shaping of the joint surfaces during embryo development.
Old World flycatchers’ family tree mapped
23 november 2022
The European robin’s closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance.

New data on violent political protest in UCDP
08 juli 2022
Violent political protest has become increasingly common across the globe, with the Middle East and Africa displaying the trend most often. This is shown in a new study conducted by peace researchers at Uppsala University. In conjunction with the study, violent political protest has as of now been introduced as its own fourth category in Uppsala University’s conflict database, known as UCDP.
New hypothesis about crocodiles’ ears may help people with impaired hearing
04 juli 2022
Impaired hearing affects over 1.2 billion people worldwide. But crocodiles, who live almost as long as humans and can surpass 70 years of age, have good hearing throughout their lives. One reason is because crocodiles 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.
Municipal housing policy influences refugee reception
30 juni 2022
Municipalities can use their local housing policy to influence 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. These are the conclusions of a new study led by the Institute for Housing and Urban Research...
