Mathematics Shows How to Ensure Evolution

New results emerging from graph theory prove that the way a population is organized can guarantee the eventual triumph of natural selection — or permanently thwart it.

Theory Suggests That All Genes Affect Every Complex Trait

The more closely geneticists look at complex traits and diseases, the harder it gets to find active genes that don’t play some part in them.

Brains May Teeter Near Their Tipping Point

In a renewed attempt at a grand unified theory of brain function, physicists now argue that brains optimize performance by staying near — though not exactly at — the critical point between two phases.

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.
