How cells navigate in messy environments

Your cells need to get around. For example, immune cells must roam around your body to locate sites of infection, and neurons must migrate to specific positions in the brain during development. But cells do not have eyes ...

New-found molecular signature keeps key genes ready for action

During development, scores of molecular signals prod cells to take on specialized identities and functions. In response to some of these signals, the cellular machinery awakens specific genes called 'immediate early genes' ...

Revealing how flies make decisions on the fly to survive

Many insects process visual information to make decisions about controlling their flying skills and movements- flies must decide whether to pursue prey, avoid a predator, maintain their flight trajectory or land based on ...
