Atmospheric circulation patterns contribute to extreme weather events
31 mars 2023
The sharp increase in heatwaves in southern Europe in recent years is not only due to the greenhouse effect. Climate change has made a particular type of atmospheric circulation pattern more common, and this has contributed to extreme weather and been the underlying cause of nine out of ten heat-related deaths. This is according to a new study by researchers from Uppsala University and CNRS in France.
Autism may be linked to different perceptions of movement in infancy
30 mars 2023
A new study from researchers at Uppsala University and Karolinska Institutet shows that children who go on to develop symptoms of autism have different activity in their brain's visual cortex from as early as five months when looking at certain types of movement. This finding may indicate that autistic people perceive their surroundings in a different way even from a very young age, which could affect their development and learning.
From living heritage to zombie churches
22 mars 2023
Churches are preserved by an antiquarian system that risks killing them instead of keeping them alive. The Swedish State and the Church of Sweden therefore need to define new joint visions and goals to enable the ecclesiastical cultural heritage to be used and developed. This is shown by historian of art Henrik Lindblad in a new doctoral thesis from Uppsala University.

Antibiotics hindered treatment of urinary tract bacteria during the pandemic
14 februari 2023
The use of broad-spectrum antibiotics increased drastically in intensive care at the beginning of the Covid-19 pandemic. At first, this helped patients avoid urinary tract infections and seemed to prevent the growth of most bacteria. However, it also contributed to a sharp growth in enterococci, an antibiotic-tolerant group of bacteria, which rendered the treatment of urinary tract infections more difficult.
Combination of immune cells could provide clearer prognoses for cancer
08 februari 2023
Thanks to a new prognostic method for detecting cancers including cancer of the large intestine, doctors could provide clearer disease prognoses and predict which patients will respond best to immunotherapy.

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
