Cover Story: Teaching Young Biologists New Tricks
Long the science where math mattered less, biology increasingly demands powerful quantitative skills. Teaching students the math they'll need, though, is more than just 1+1=2.

Invisible Barriers
Children with the subtlest form of autism suffer social isolation; those with more severe disease face a much tougher road. New genetic clues put the spotlight on the communication hubs of the brain's neurons–the synapses.

Genetic Balancing Act
Animals have evolved intricate ways to ensure that gene activity is the same in males and females despite the inherent imbalance of X chromosomes.

Sources of Renewal
As scientists learn more about how to produce and manipulate stem cells–amid high expectations and close scrutiny–no one is ready to choose any one approach over another.
