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 ...
Deep within an ancient sinkhole lie the remains of dozens of mammoths, prehistoric wanderers who waded into the warm springs to their deaths. These deaths had long been accepted as having occurred roughly 26,000 years ago, ...
The malaria parasite is able to detect changes in its host's environment and respond by increasing the production of sexual forms capable of being transmitted to mosquitoes. A study led by the Barcelona Institute for Global ...
