The minds at DARPA are creating another batch of sci-fi-worthy tools to fend off most any kind of enemy (and shape up civilian life too)
To get the upper hand in any scenario, the U.S. military has often relied on the most outlandish innovations the mind can conjure. Stealth technology, bionic limbs, and a little thing called the Internet all started with the military— specifically, as brainchildren of the Defense Advanced Research Projects Agency (DARPA), the 60-year-old fount of new technology in soldiering. RD reviewed the next wave of advances, looking for those destined to spread.
1 POWER WALKERS
Spend time speaking with foot soldiers, and you’ll eventually hear about lugging an overstuffed backpack for miles in terrible weather through rough terrain. But the age-old problem of overburdened troops is deadly serious: An army on the move can be dangerously slowed and weakened by strain injuries or just by soldiers struggling under their loads.
So the minds at DARPA threw down this gauntlet to the scientific community: Build some kind of wearable contraption that would help combatants transport their burdens. It needed to be thin and supple enough to fit under battle uniforms and equipment.
To come up with a solution, Ignacio Galiana, PhD, and his researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering immersed themselves in studying a simple act we take for granted: walking. They scrutinized the leg muscles’ perfectly timed bursts of energy to understand how a walker might get a little assist. “What we learned,” says Galiana, “is that small changes in timing—just a few milliseconds—could make a difference between assisting and hindering someone.”

Do You Kiss Your Dog? - Find out how gross your questionable habits really are, according to health experts
I admit it, when it comes to food, I have some eeew-inducing practices, like skimming mold off old cheddar and feeding the rest to my unsuspecting family. We're still alive, so how bad can it be? Because our gross human habits fall somewhere along the spectrum from mildly cringeworthy to full-on repulsive, I reached out to experts to find out where some common behaviors land on the gross-o-meter.
What's Ailing Our Doctors? - Today's physicians are burned out and battered by spreadsheets. We patients suffer too.
Today’s physicians are burned out and battered by spreadsheets. We patients suffer too. America's doctors are in crisis. Six in 10 physicians say they're burned out, with burnout rates for some specialties, such as primary care, reaching 70%. When polled by the American Medical Association, 40% of doctors said they were considering leaving their practices in the next two years. Another study, conducted by health-care industry publisher Elsevier, revealed concerns about mental health and burnout: 63% of med students in the United States reported that they had no intention of practicing clinical medicine after graduation and will instead work as lab researchers or academics. This is despite a predicted shortage of 124,000 physicians over the next 10 years.
