Teeth from Chinese cave recast history of early human migration

By Will Dunham WASHINGTON (Reuters) - A trove of 47 fossil human teeth from a cave in southern China is rewriting the history of the early migration of our species out of Africa, indicating Homo sapiens trekked into Asia far earlier than previously known and much earlier than into Europe. Scientists on Wednesday announced the discovery of teeth between 80,000 and 120,000 years old that they say provide the earliest evidence of fully modern humans outside Africa. The teeth from the Fuyan Cave site in Hunan Province's Daoxian County place our species in southern China 30,000 to 70,000 years earlier than in the eastern Mediterranean or Europe.

(Bee)autiful Shot: Pollen-Covered Eyeball Wins 'Small World' Photo Contest

More than 2,000 photographers submitted images to the 2015 Nikon Small World Photomicrography Competition, but just 20 of those images were chosen as winners. The first-place picture of the bee's eye was taken by Australian photomicrographer Ralph Grimm, who spent 4 hours mounting the eye under a microscope and focusing the instrument to capture the stunning shot. Grimm, a high school teacher and former beekeeper, said that, in light of the ongoing collapse of bee colonies worldwide, he hopes his image is a reminder of the important role these pollinators play in local ecosystems.

Two Small Pluto Moons Get Their Close-Ups (Photos)

Pluto's small moons are starting to come out into the light. The most jaw-dropping photos captured by NASA's New Horizons spacecraft during its historic July flyby of Pluto depict the dwarf planet or its largest moon, Charon. "Nix isn't very large, and there is a very fine line between an impact that will make a crater that big and one that will break Nix apart," New Horizons team member Simon Porter, of the Southwest Research Institute in Boulder, Colorado, wrote in a blog post last week.

Science of Sexy: Why Emilia Clarke Reigns Supreme

In many ways, it's not surprising Esquire picked Clarke, who plays the fearless dragon rider and rightful heir to the Iron Throne on Game of Thrones. Data from the dating website OkCupid reveals that men up to the age of 50 rate women between the ages of 20 and 24 the most beautiful. "From the time you're 22, you'll be less hot than a 20-year-old, based on this data," Christian Rudder, one of the founders of OkCupid, told fivethirtyeight.com.

Lilly pill trumps Humira in arthritis study

(Reuters) - Eli Lilly and Co's experimental pill for rheumatoid arthritis proved superior to Abbvie Inc's leading injectable Humira treatment in a large study, which analysts said could prod them to raise sales forecasts for the medicine. Lilly said on Wednesday it was the first study to show that a once-daily oral treatment was superior to $13 billion-a-year Humira, the world's best-selling drug, in improving signs and symptoms of rheumatoid arthritis. It was the fourth successful late-stage trial for Lilly's medicine, called baricitinib, which it is developing in partnership with Incyte Corp. "What is disclosed is quite impressive - about as good an outcome as Lilly could hope for," Sanford Bernstein analyst Tim Anderson said in a research note.

New 'Habitability Index' Could Help Guide Search for Alien Life

The "habitability index" metric could help guide the operations of future observatories, such as NASA's James Webb Space Telescope (JWST), that will scan exoplanet atmospheres for signs of life, scientists said. "Basically, we've devised a way to take all the observational data that are available and develop a prioritization scheme so that as we move into a time when there are hundreds of targets available, we might be able to say, 'OK, that's the one we want to start with," study lead author Rory Barnes, of the University of Washington, said in a statement. Traditionally, assessing habitability has been a yes-or-no affair, with researchers attempting to determine whether or not an alien world resides in the "habitable zone" of its host star.

Ultrathin Microlenses Could Boost Space Science and Tech

"These flat lenses will help us to make more-compact and robust imaging assemblies," Mahmood Bagheri, a microdevices engineer at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said in a statement. Typical lenses, such as those used in eyeglasses or magnifying glasses, rely on curvature to bend and focus light. The new flat lenses can manipulate light in ways that are nearly impossible for conventional lenses, and they take up less space, allowing for smaller electronics.

Bye, Bye, Playboy Bunnies: 5 Ways Porn Affects the Brain

Playboy Magazine announced yesterday (Oct. 12) that it was revamping its design. "Playboy's great success was that it legitimized sexualized images in the context of good fiction, interesting articles and groundbreaking interviews," Kim Wallen, a psychologist at Emory University in Atlanta, Georgia, wrote in an email to Live Science. The magazine, which first exploded into public consciousness when it published nude shots of Marilyn Monroe in 1953, has been losing readers for years, according the Alliance for Audited Media., largely thanks to the rise of Internet pornography.

Solar plane prepares for Amazon mission

By Jim Drury Student engineers from ETH Zurich are preparing to fly their world-record breaking solar plane over the Amazon rainforest. The team is fitting its AtlantikSolar unmanned aerial vehicle (UAV) for a 400 kilometer, 12 hour, flight as it seeks to push the endurance limits of solar planes. The team broke the flight endurance world record for any aircraft below 50 kilograms by flying continuously on solar powered batteries for 81.5 hours (over four days and three nights) in Zurich.

Repaired SpaceX rocket to fly by early December, company says

Space Exploration Technologies, or SpaceX, expects to return a repaired and upgraded Falcon 9 rocket to flight around the start of December, a company vice president said, less than six months after one exploded shortly after liftoff. The 208-foot-tall (63-meter) rocket carrying cargo for the International Space Station exploded less than three minutes after liftoff from Florida on June 28. The cause of the accident was traced to a faulty bracket inside the rocket’s upper-stage engine.

Israeli engineer designs grounded drone delivery service

Israeli industrial designer Kobi Shikar has come up with the concept of a parcel delivery drone that will never get off the ground - and that's just fine with him. The Transwheel Delivery Drone is a sensor-packed motorized unicycle that Shikar says could be an earthbound alternative to Amazon's futuristic plans to use drone multicopters to deliver packages to your front door. It's a compromise, Shikar believes, between the need for speedy delivery and the dangers of flying drones encroaching on commercial airspace.

Mom's Stress During Pregnancy Tied to Teen's Coordination Problems

Children born to women who experienced stressful events during pregnancy may be less coordinated in their body movements as teenagers, according to a new study. The new findings suggest that "programs aimed at detecting and reducing maternal stress during pregnancy" may improve the long-term outlook for these children, study author Beth Hands, professor of human movement at the University of Notre Dame Australia, said in a statement. In the study, doctors asked 2,900 women in Australia twice during their pregnancies — at 18 weeks and 34 weeks — whether they had experienced stressful events while they were pregnant.

Listeria Outbreak Mystery: Weird Chemistry Tainted Caramel Apples

Researchers may have finally found the source of a 2014 Listeria outbreak that was traced to caramel apples, a new study finds. Caramel apples were not considered to be a hospitable breeding ground for the disease-causing bacteria, Listeria monocytogenes. The juice from apples is acidic, and that acidity makes it hard for bacteria to grow, said Kathleen Glass, the associate director of the University of Wisconsin-Madison's Food Research Institute and lead author on the study.
