'Sailing Stones' of Death Valley Caught in the Act

August 29, 2014 7:00 am | by Scripps Institution of Oceanography Videos Comments

Racetrack Playa is home to an enduring Death Valley mystery. Littered across the surface of this dry lake are hundreds of rocks– some weighing as much as 700 pounds– that seem to have been dragged across the ground, leaving synchronized trails that can stretch for hundreds of meters. What powerful force could be moving them? Researchers have investigated this question since the 1940s, but no one has seen the process in action– until now.

Sprinters Punch Ground for Speed

August 28, 2014 7:00 am | by Southern Methodist Univ. Videos Comments

The world’s fastest sprinters have unique gait features that account for their ability to achieve fast speeds, according to two new studies. The new findings indicate that the secret to elite sprinting speeds lies in the distinct limb dynamics sprinters use to elevate ground forces upon foot-ground impact.

Cells Can Be Sorted with Sound

August 27, 2014 7:00 am | by MIT, Anne Trafton Videos Comments

Researchers have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Their device, about the size of a dime, could be used to detect the extremely rare tumor cells that circulate in cancer patients’ blood, helping doctors predict whether a tumor is going to spread.

Research Key to Cyborg Moth 'Biobots'

August 21, 2014 7:00 am | by North Carolina State Univ. Videos Comments

Researchers have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals moths use to control those muscles. The work opens the door to the development of remotely controlled moths, or “biobots,” for use in emergency response.

Immune System Dazed, Confused During Spaceflight

August 20, 2014 7:00 am | by NASA Videos Comments

Researchers have a good idea what causes immune system changes on Earth— things like stress, inadequate sleep and improper nutrition. New research suggests that spaceflight may temporarily alter the immune system of crew members flying long-duration missions aboard the ISS.
