A highly dexterous robot hand can operate in the dark – just like us. Columbia engineers designed the first-of -its-kind device, which joins advanced sense of touch with motor-learning algorithms.

Elephant seal brainwave patterns have revealed these mammals take short naps while holding their breath on deep dives. Researchers had been mystified how they got enough sleep while foraging at sea, as each seal averages about 2 hours of sleep each day.

The NSF announced a nearly $92 million investment in the University Corporation for Atmospheric Research – or UCAR – to build a state-of-the-art airborne radar. Attached to planes, it can provide remarkable detail of inside clouds and deep in storms.
