Thousands of tiny quakes shake Antarctic ice at night

Posted: 04 Mar 2019 12:49 PM PST

Scientists placed seismometers on the McMurdo Ice Shelf and recorded hundreds of thousands of tiny ‘ice quakes’ that appear to be caused by pools of partially melted ice expanding and freezing at night. The phenomenon may be able to help scientists track glacier melting — and to help explain the breakup of large ice shelves.

Mini cheetah is the first four-legged robot to do a backflip

Posted: 04 Mar 2019 10:42 AM PST

New mini cheetah robot is springy and light on its feet, with a range of motion that rivals a champion gymnast. The four-legged powerpack can bend and swing its legs wide, enabling it to walk either right-side up or upside down. The robot can also trot over uneven terrain about twice as fast as an average person’s walking speed.

    

The case of the over-tilting exoplanets

Engineers develop fast method to convert algae to biocrude

Posted: 04 Mar 2019 06:58 AM PST

A team of chemical engineers have developed a new kind of jet mixer for creating biomass from algae that extracts the lipids from the watery plants with much less energy than the older extraction method. This key discovery now puts this form of energy closer to becoming a viable, cost-effective alternative fuel.
