“Blind” Cheetah 3 robot can climb stairs littered with obstacles
The new design could help the robot explore disaster zones and other dangerous environments.
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.
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.
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.
Study of quark speeds finds a solution for a 35-year physics mystery
Number of proton-neutron pairs determine how fast the particles move, results suggest.

MIT physicists now have an answer to a question in nuclear physics that has puzzled scientists for three decades: Why do quarks move more slowly inside larger atoms?
