Experiments in mice find the link between movements and the brain activity of certain groups of neurons, highlighting a fundamental way in which brain and body dynamics are coordinated.

A treatment that mimics a fat-burning stress hormone prevents obesity and inflammatory liver disease in mice fed a high-fat diet.

Rare, strong links between neurons provide a reliable route for signals to travel through the brain, while weaker connections can alter this route depending on the external conditions.

Two proteins form a stable complex to establish physical barriers that hinder the copy of certain regions of DNA in the cells of fruit fly larvae.

The proteins responsible for tightly packaging DNA into sperm evolve quickly, perhaps due to their role in killing sister sperm, or in suppressing that killing.

People consider non-human sources of information as less reliable than other humans and are less likely to reassess human sources despite being given contradictory advice.

Genetics and mathematical modelling shed new light on how cells coordinate how much type I interferons they produce during a viral infection.

Cadherin proteins, which help to attach cells together, are essential to shape the neural networks that preside over respiration.
