Star formation in galactic centers

Stars form from the gas and dust in molecular clouds via a series of complex processes that are currently only partly understood, and the evolution of these clouds drives the evolution of the stellar populations in the universe. ...

Gene activity in defenders depends on invading slavemaking ants

Temnothorax americanus is a slavemaking ant found in northeastern America. These tiny social insects neither rear their offspring nor search for food themselves. Instead, they raid nests of another ant species, Temnothorax ...

Scientists develop new theory of molecular evolution

Researchers from the University of Colorado Anschutz Medical Campus and the University College London have developed a new theory of molecular evolution, offering insights into how genes function, how the rates of evolutionary ...

New discovery challenges long-held evolutionary theory

Monash scientists involved in one of the world's longest evolution experiments have debunked an established theory with a study that provides a 'high-resolution' view of the molecular details of adaptation.

Dino-killing asteroid sped up bird evolution

Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn ...
