MIT's Cheetah 3 robot can now leap and gallop across rough terrain, climb a staircase littered with debris, and quickly recover its balance when suddenly yanked or shoved, all while essentially blind.

Breaching a “carbon threshold” could lead to mass extinction

Study finds that carbon dioxide emissions may trigger a reflex in the carbon cycle, with devastating consequences.

Surprising Science

In the brain, when neurons fire off electrical signals to their neighbors, this happens through an "all-or-none" response. The signal only happens once conditions in the cell breach a certain threshold.

An escape route for carbon

Study shows minerals sequester carbon for thousands of years, which may explain oxygen's abundance in the atmosphere.

Surprising Science

As many of us may recall from grade school science class, the Earth's carbon cycle goes something like this: As plants take up carbon dioxide and convert it into organic carbon, they release oxygen back into the air.
