Parakeets, male or female, love a good fight
In a study of monk parakeets, researchers at the University of Cincinnati and Duke University found that sex has little to no impact on who initiates fights, who is targeted or who rises in the dominance hierarchy.

Antibody cocktails could steer viruses into evolutionary dead ends
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS-CoV-2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study from Harvard's ...

Radiation-tolerant rotifers rebuild broken chromosomes over successive generations
DNA repair mechanisms are essential for maintaining the integrity of our genome. When they malfunction, they can cause disease or contribute to the development of cancer. Nature, however, offers remarkable examples of organisms ...

Scientists discover dispersal mechanism and new gene family in harmful E. coli strains
Researchers from Tokyo Metropolitan University have identified how certain dangerous bacteria spread. They studied chain-like adherence pattern (CLAP) varieties of Shiga toxin-producing E. coli (STEC), finding that single ...

Structural study explains how cells stabilize protective membrane pockets
Our cells' membranes have many functions. They not only provide mechanical protection but also precisely control which substances enter or leave cells. If they fail to perform these tasks, disease can result. Their structure ...

The surprising history of woolly rhinos: They weren't always creatures of the frozen north
Woolly rhinoceroses (Coelodonta antiquitatis) were fascinating creatures: giant, lumbering Ice Age beasts with thick fur and massive horns that died out about 11,000 years ago. Previous genetic studies had left open the question ...
Chocolate's new climate threat: Too much rain
Cocoa farmers in West Africa cannot stop intense downpours from damaging their crops. But they may be able to anticipate the risk and prepare, protecting both their livelihoods and their plants, the source of one of the world's ...

Cancer-linked protein binds to chromosome in unexpected way, study finds
A new 3D structure of a cancer-linked protein bound to its cellular partner reveals details of how the protein binds to chromosomes and could offer insights for future disease treatments. The protein—BRD4—plays a critical ...

Three DNA loops prove essential for efficient wing tissue regeneration in fruit flies
After an injury, DNA not only changes its activity but also the way it is organized spatially within the cell nucleus. In this process, certain regions of DNA establish new physical contacts through chromatin loops that act ...

Forest fire smoke reduces bird diversity, study suggests
When forests burn, the direct consequences are obvious: houses go up in flames and habitats are destroyed. The damage caused by smoke extending far beyond the fire area is less visible. Sarah Meier, an environmental economist ...
