Robotic Arm Aims to 'Repay Some of the Debt' to Wounded Warriors A robotic arm commissioned by the U.S. Department of Defense to "repay some of the debt" owed to wounded military service members has been approved by the U.S. Food and Drug Administration eight years after its inception. The cutting-edge prosthetic, known as the DEKA Arm System, was dreamed up in 2006 as part of a "Revolutionizing Prosthetics" program at the Defense Advanced Research Projects Agency, better known as DARPA. "DARPA is a place where we can bring dreams to life," said Dr. Geoffrey Ling, director of DARPA's Biological Technologies Office and a retired Medical Corps neuro-critical care doctor. Ling launched the Revolutionizing Prosthetics program to provide better care "to repay some of the debt we owe to our service members," according to a statement. The battery-powered arm, developed by DEKA Integrated Solutions in Manchester, N.H., uses wireless signals activated by sensors on the feet to move multiple joints and has six user-selectable grips that can handle delicate objects like grapes and eggs as well as hardy tools like power drills. It was approved on Friday for adults based on the results of a Department of Veterans Affairs-funded study of 36 patients.

Chihuahua Rescue on Highway Creates Social Media Sensation A big-hearted California Highway Patrol officer saved a terrified Chihuahua from a busy highway's divider, and the picture of the rescue has become a social media sensation. Officer Alex Edmon plucked the female Chihuahua, which he named "Freeway," from a highway divider in a San Francisco suburb during rush hour Friday afternoon. "This little dog needed some help off I-680 freeway today. We're glad he's safe," read a tweet from the California Highway Patrol in Contra Costa County. "We're big on saving lives," a subsequent tweet from California Highway patrol read. The rescue picture has since been re-tweeted nearly 1,000 times and has garnered more than 700 "favorites," as of this writing. Officer Edmon spotted the pup along the freeway and coaxed her into his arms using a protein bar, California Highway Patrol Public Information Officer John Fransen told ABC News today. The tiny dog was uninjured and taken to a shelter in Martinez, California, by county animal services personnel. Fransen said the California Highway Patrol division in Contra Costa County was investigating how the puppy wound up on the divider in the first place. "There is no way he could have got there by himself," he said.
