Explainer: Cells and their parts
Life as we know it depends on the coordination of structures inside cells — whether a living thing has only a single cell or trillions of them.

A new drug mix helps frogs regrow amputated legs
The treatment helped frogs grow working limbs useful for swimming, standing and kicking. It’ll be a while before people can do that.

In blazing heat, some plants open leaf pores — and risk death
When heat waves and droughts collide, water is precious. Some thirsty plants try to cool off by opening tiny pores — only to lose water even faster.

Genes point to how some bacteria can gobble up electricity
A new study shows how some microbes absorb and release electrons — a trait that may point to new fuels or ways to store energy.
