Overtaxed Working Memory Knocks the Brain Out of Sync
Researchers find that when working memory gets overburdened, dialogue between three brain regions breaks down. The discovery provides new support for a larger concept about how the brain works.
Scientists Map the Genetic Steps as Eggs Become Animals
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.
