China’s Taklamakan Desert

COVERT CARBON  Desert aquifers, fed by rain, surface and irrigation waters, hoard hundreds of billions of metric tons of carbon pulled from the atmosphere, new research suggests.

Philae

TAKE TWO   Philae’s intended landing spot (left, imaged from 40 meters above the comet’s surface) was soft and sandy. A two-hour-long bounce dropped it in a craggy pit (right, with lander leg at bottom) where the ground is as hard as pumice.

Arctic Ocean

HOT WATER  The Arctic Ocean will be ice-free almost a decade earlier than previously predicted, new calculations suggest.

water strider

FLOATING  Like a real water strider (left), new robotic insects can rest on water and jump off it.
