Little African primate's talents inspire leaping robot

By Will Dunham WASHINGTON (Reuters) - Inspired by the remarkable jumping ability of an African primate called a galago, scientists have fashioned a small robot with unique leaping capabilities they hope can someday be used in tricky search-and-rescue situations. The scientists said on Tuesday they had built a robot, dubbed Salto, with vertical jumping agility like no other machine, able to leap into the air and then spring off a wall, or perform multiple vertical jumps consecutively. To design Salto, short for "saltatorial locomotion on terrain obstacles," the University of California, Berkeley, researchers sought inspiration from one of the animal kingdom's best leapers.

2 Million Pounds of Ready-to-Eat Chicken Recalled: Here's Why It's Risky

On Sunday (Dec. 4), the food manufacturing company National Steak and Poultry announced a recall of more than 1.9 million pounds of the products, which were produced from Aug. 20, 2016, through Nov. 30, 2016, according to a statement from the U.S. Department of Agriculture. The recalled products may have been undercooked, and so they have the potential to contain bacteria, the USDA said. The bacterial pathogens most commonly linked with raw chicken are Salmonella and Campylobacter, said Benjamin Chapman, an associate professor and food safety specialist at North Carolina State University.

Lack of Sun in Teen Years Linked to Nearsightedness Later On

Teens and young adults who spend more time outdoors may be less likely to become nearsighted later in life than those who spend less time outdoors, a new study suggests. People in the study who spent more time exposed to ultraviolet B (UVB) radiation — which the researchers calculated based on the participants' exposure to sunlight — between ages 14 and 39 were less likely to be nearsighted at 65 than those who spent less time exposed to UVB radiation, the researchers found. "Increased UVB exposure was associated with reduced myopia, particularly in adolescence and young adulthood," the researchers wrote in the study, published yesterday (Dec. 1) in the journal JAMA Ophthalmology.

Here Are the States with the Lowest & Highest Diabetes Rates

Diabetes is on the rise in the United States, and a new poll looks at where the disease is most and least common. In the poll, from Gallup-Healthways, researchers surveyed a nationally representative sample of more than 176,000 Americans in all 50 states in 2015. The participants were asked whether they had ever been diagnosed with diabetes in their lifetime.

Mammoth Fossils Found at Site of LA Subway Dig

Fossils from giant, ice age-beasts were uncovered while workers were digging an extension to the Los Angeles subway system. The finds include a 3-foot-long (1 meter) section of mammoth tusk, as well as a skull and partial tusks from a much younger animal, which might have been either a mammoth or a mastodon, according to The Source, a transportation blog about the L.A. Metro. Though the ice-age fossils (whose exact age has not yet been determined) are certainly treasures that are rarer to unearth under the subway than rat "fossils" and "coprolites," old chicken wings or discarded coffee cups, the finds actually aren't all that surprising.

Humpback Whales 'Mug' Boat in South Pacific (Video)

A new National Geographic video showing humpback whales in a graceful ballet around a passenger boat in the South Pacific is a whale-watcher's dream. Sometimes they stay for mere minutes, said Stephanie Stack, a marine biologist at the Pacific Whale Foundation in Hawaii. Regulations prevent boat captains from running their engines within 100 yards of a whale, Stack told Live Science.
