A research group working at Uppsala University has succeeded in studying ‘translation factors’ – important components of a cell’s protein synthesis machinery – that are several billion years old. By studying these ancient ‘resurrected’ factors, the researchers were able to establish that they had much broader specificities than their present-day, more specialised counterparts.
A comprehensive study from Uppsala University demonstrates that socioeconomic deprivation modifies genetic effects on higher education and abstract reasoning. The paper illustrates how genes play a greater role in educational attainment in more socioeconomically deprived regions of the United Kingdom. The study was recently published in the American Journal of Psychiatry.
Researchers at Uppsala University have now discovered that one of the most common immune cells in the human body, macrophages, play an important role in re-establishing and controlling blood flow, something that can be used to develop new drugs.
David D. Laitin, Stanford University, is this year’s recipient of the Johan Skytte Prize, known by many as the ‘Nobel Prize in Political Science’. Professor Laitin is awarded the prize for his “original and objective explanation of how politics shapes cultural strategies in heterogeneous societies.”
To maximise absorption of nutrients from the diet, the intestinal mucous membrane has a large surface area. However, this also makes it vulnerable to attack from aggressive gut microbes. A new study by Uppsala University researchers now shows that the surface layer of the mucosa, known as the epithelium, can rapidly contract when it recognises a bacterial attack.
While studying genetic diversity in bumblebees in the Rocky Mountains, USA, researchers from Uppsala University discovered a new species. They named it Bombus incognitus and present their findings in the journal Molecular Biology and Evolution.
Over 50 millennia, at least five major immigration waves have successively populated the Philippines, the most comprehensive survey of genetic variations in the country to date shows. This Uppsala University study, published in the scientific journal PNAS, comprises 2.3 million DNA markers from some 1,000 individuals.
Mutations in the neurochondrin (NCDN) gene can cause epilepsy, neurodevelopmental delay and intellectual disability. The gene mutation significantly impairs contacts and signalling between neurons in the brain. This is the conclusion of a study led from Uppsala University and published in the American Journal of Human Genetics.
Mantle cell lymphoma is a malignant disease in which intensive treatment can prolong life. In a new study, scientists show that people with mantle cell lymphoma who were unmarried, and those who had low educational attainment, were less often treated with a stem-cell transplantation, which may result in poorer survival. The findings have been published in the scientific journal Blood Advances.
In asthma, the airways become hyperresponsive. Researchers from Uppsala University have found a new mechanism that contributes to, and explains, airway hyperresponsiveness. The results are published in the scientific journal Allergy.
Researchers at Uppsala University have developed a digital self-test that trains users to assess news items, images and videos presented on social media. The self-test has also been evaluated in a scientific study, which confirmed the researchers’ hypothesis that the tool genuinely improved the students’ ability to apply critical thinking to digital sources.
Antimicrobial resistance is an urgent global threat to human and animal health. This year’s Uppsala Health Summit, which will take place online on 15–18 March, will discuss how behaviour change across various sectors of society can slow down this worrying trend.
