Why do zebras have stripes? A study published in PLOS ONE today takes us another step closer to answering this puzzling question and to understanding how stripes actually work.
One of the largest field experiments ever conducted is providing the best evidence yet in support of a key Darwinian theory—that interactions between species are stronger toward the tropics and at lower elevations.
Male flies kept awake do not die earlier than those allowed to sleep, leading researchers to question whether sleep, in flies at least, is essential for staying alive.
The very early days of growth, long before we are born, are a time of incredible development. In a relatively short period of time, we and other mammals create our bodies' dozens of different organs from a few thin layers ...
Try as you might, some events cannot be remembered. Known in psychology as memory blocking, the phenomenon has remained elusive since first described more than half a century ago. Now Donnelly Centre researchers have found ...
A female stickleback fish, nick-named 'Mary', has produced offspring from eggs that appear to have been fertilised while they were still inside her, according to scientists at the University of Nottingham.
The connection between bird diet and skull shape is surprisingly weak for most species according to a new study led by UCL and the Natural History Museum, rewriting our understanding of how ecosystems influence evolution.
Scientists have discovered that grasses are able to short cut evolution by taking genes from their neighbours. The findings suggest wild grasses are naturally genetically modifying themselves to gain a competitive advantage.
