The availability of prey and the ability to adapt to changing environments played key roles in the evolution of sharks. A new study, in which over 3,000 shark teeth were analysed, provides new insight into how modern shark communities were established. The results are published in the journal Current Biology.
Can T-cell tests be used to determine whether people have had COVID-19? Scientists at Uppsala University and Karolinska Institutet have jointly analysed this issue under the aegis of the COMMUNITY study at Danderyd Hospital. Their study is published in the scientific journal PLOS ONE.
Researchers at Uppsala University have designed new antibodies that might provide more effective treatment methods for Alzheimer’s disease. By designing antibodies that bind even to the smaller aggregates, or clumps, of the amyloid-beta protein, it may be possible to check the progress of the disease. The results presents in Translational Neurodegeneration.
Mast cell precursor cells do not just cause an increase in mature mast cells during inflammation, they also play an active role in diseases like asthma. This finding is in a new study by immunology researchers published in the Journal of Allergy and Clinical Immunology. The study also emphasises that precursor cells in general can play an active role in inflammation and challenges the current ide
Changes in individual cancer cells over time may explain why brain tumours develop so differently, and why some cancer cells are resistant to certain treatments. To track the development of cancer cells, researchers at Uppsala University have devised a new method that, in the long term, may make it easier to develop new, effective drug combinations.
Men’s sleep may be more powerfully influenced by the lunar cycle than women’s, according to a new study from Uppsala University, now published in the journal Science of the Total Environment.
On 17 September 2021, the annual Dag Hammarskjöld Lecture will take place at Uppsala University’s Aula Magna. This year’s event features both the 2021 Lecture by Dr. Agnès Callamard, Secretary General of Amnesty International, and the 2019 Lecture by Christiana Figueres, chief architect of the 2015 Paris Agreement on Climate Change, which was previously postposed. Journalists and representatives o
How the cell can mend broken DNA using another DNA copy as template has puzzled researchers for years. How is it possible to find the correct sequences in the busy interior of the cell? Researchers from Uppsala university have now discovered the solution; it is easier to find a rope than a ball if you are blindfolded.
“The school system is not fulfilling its compensatory mission. Instead, it is entrenching the inequalities of life opportunities among children and youth, and social reproduction and segregation,” says Göran Nygren, researcher at the Department of Cultural Anthropology and Ethnology at Uppsala University, who recently defended his thesis.
Determining an individual’s blood group based on genetic tests instead of merely traditional blood tests can provide a better picture of the risk of cardiovascular diseases. If a patient has two genetic variants of A, B or AB, the risk is twice as high compared with if one is O. This is the finding of a new study from the Uppsala University using data from UK Biobank.
An international team of researchers used historical museum collections to study the effects of human-made antibiotics over the entire history of their application. They found that the increased use of antibiotics in medicine and agriculture in the 1950-1990s led to increases in antibiotic resistance in wild Swedish brown bears. However, the latest 20 years show a downward trend in resistance.
Females and males differ in many ways and yet they share the same genome. The only exception is the male Y chromosome. Using beetles as a study system, new research from Uppsala University, now published in Nature Ecology & Evolution, shows that despite of the Y chromosome containing very few genes, it can dramatically change male body size and thus facilitate the evolution of sex differences.
