Video Powered Exoskeletons Give Assistance in Walking, Lifting

Powered suits that could help paralyzed people walk and others lift and carry heavy loads with ease have been an inventor's dream since late 19th century. Today's advanced materials, motors and power sources bring such devices closer to practical use. VOA's George Putic reports.

Video Study: Fish Use Whole Bodies When They Eat

About half of all vertebrates – those animals with a back bone – are fish with bony rays or spines. These 30,000 ray-finned fish species have evolved a similar feeding motion. As VOA's Rosanne Skirble reports, scientists have long hypothesized about the mechanics of that process, but now researchers at Brown University have x-ray video that shows it in action, in great detail.

Video One-Person Flying Vehicles Close to Reality

Smart phones, essentially pocket-sized computers, we already have. Flying drones with cameras are available to everybody. Robots and self-driving cars are just around the corner. Now, two groups of inventors say very soon we will be able to try flying platforms and flying bikes. VOA’s George Putic has more.

Video Scientists Explore How Brains Work During Conversations

What goes on in our brains as we engage in a simple conversation? Using a new technology, scientists at Yale University are trying to understand, among other things, what prevents autistic children from developing communication skills. VOA’s George Putic reports.

Video 3-D Printing Can Efficiently Create Prosthetics

People who are missing a hand or an arm traditionally would have to pay thousands of dollars and wait for weeks for an artificial one, called a prosthesis. But 3-D printing is providing a much cheaper and faster alternative. 3-D-printed hands are changing the lives of children around the world. One such child lives in a town just south of Los Angeles. Elizabeth Lee reports for VOA.

Video New Device Detects Pilot Blackouts

During certain maneuvers, jet fighter pilots sometimes experience loss of vision and even loss of consciousness. Although short, these so-called ‘blackouts’ may have tragic consequences. An Israeli company says it has developed a device that could save pilots’ lives at such moments. VOA’s George Putic reports.

Video Chemical-Sniffing Technology Fights Australia's Graffiti Vandals
