Layered deposits of coral skeletons hold vast stores of environmental data from thousands of years ago, including annual records of ocean temperatures, water pollution and storm activity.
By paying more attention to behaviors, and not just the activity of neurons, two researchers critical of most neuroscience learned how brains make sense of spoken language.
Faced with a navigational challenge, neural networks spontaneously evolved units resembling the grid cells that help living animals find their way.
For the first time, researchers have traced the genetic programs that guide the development of each cell in early embryos. Surprisingly, even cells that start out different can end up the same.
To date the branches on the evolutionary tree of life, researchers are looking at horizontal gene transfers among ancient microorganisms, which once seemed only to muddle the record.
