Pathogenic virus infects and structurally reorganizes human cells, finds new study
Orthohantaviruses, such as the Puumala virus, are widespread in Europe, causing flu-like illnesses and severe kidney damage in those infected. It is increasingly considered a zoonotic threat. Researchers from the Medical Faculty of the University…

Many wild bee species find home on a university campus
170 species of wild bees live on the Hubland Campus of Julius-Maximilians-Universität Würzburg (JMU). This is the result of a study carried out by the Chair of Animal Ecology and Tropical Biology at the JMU Biocentre from 2012 to 2023. The…

How changes on the Y chromosome may make species reproductively incompatible
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males first, with hybrid males frequently failing to produce functional sperm even when hybrid females remain fertile. In a new…

A brighter future may not suit everyone: Polar cod face difficulties due to warming
Under the Arctic sea ice, fish and plankton live in complete darkness, even in midsummer. Ice floes stop the sun’s rays, especially if they are covered by snow. As the ocean heats up, the sea ice thaws, and new regions are exposed. A recent study…

Narrow-ridged finless porpoises are more social than assumed, study finds
A well-established fact of infancy in mammals is that the mother is the primary adult with whom an infant will interact. This holds true across species, from the tiniest shrew to the most massive blue whale. However, infants of many species also…

Recent pandemic viruses jumped to humans without prior adaptation, study finds
A new University of California San Diego study published in Cell challenges a long-standing assumption about how animal viruses become capable of sparking human epidemics and pandemics. Using a phylogenetic, genome-wide analysis across multiple…

The Ratio of Fats in Diet Has a Significant Effect on Immunity
Our diet can affect our health in different ways–diet directly impacts the calories and nutrients we consume; it can influence metabolic functions; or have a major effect on the gut microbiome, for some…

Why simulating an entire cell cycle took years, multiple GPUs and six days per run
By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell division—scientists have opened a new frontier of computer vision into the essential processes of life. The…
