SpaceX to retry ocean rocket landing after success on land

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Technology entrepreneur Elon Musk's SpaceX will attempt to land its next Falcon 9 rocket on a barge in the Pacific Ocean, seeking another milestone a month after landing a booster on the ground in a spaceflight first, the company said on Friday. The Falcon 9 rocket, carrying a NASA ocean-monitoring satellite, is slated to blast off from Vandenberg Air Force Base in California on Jan. 17. About two minutes after liftoff, the first stage of the rocket will separate, flip around, fire engines to slow its fall, deploy landing legs and attempt to touch down on a floating landing pad in the Pacific Ocean.

Paper airplanes go high-tech at CES

By Ben Gruber The humble paper airplane has just been given a digital upgrade. Israeli firm PowerUp Toys showed off a paper plane equipped with some of the latest drone technology at this week's Consumer Electronics Show (CES) in Las Vegas. "We are actually introducing first person view flight (FPV) to paper airplanes. So you experience flight as if you were a pilot but on a paper airplane that you folded, which is kind of crazy," said PowerUp Toys CEO, Shai Goetein. It's certainly crazy, but Goetein thinks consumers will find it fascinating. ...

3 High-Tech Ways to Track What You Eat

One gadget, called DietSensor, claims to be able to scan your food with a beam of light and tell you its nutritional content, such as how much protein, fat and carbohydrates it contains. It does this by analyzing how the molecules in the food interact with the light, according to the company, which presented the device here at CES. This causes the molecules in the food to vibrate, and produce an optical signature that is unique for that food, the company says.

Got Allergies? Blame Neanderthals

Genetic variants found in modern humans that originally came from Neanderthals may predispose the human immune system to overreact to environmental allergens, according to two new studies published today (Jan. 7) in the American Journal of Human Genetics. The studies also found that interbreeding with Neanderthals may have helped ancient humans, who came from Africa, get a head start in settling Europe. "Neanderthals, for example, had lived in Europe and western Asia for around 200,000 years before the arrival of modern humans.

Why Crows Hold Funerals

The scientists cited an earlier study showing that American crows gather and act aggressively, behavior known as "mobbing," in response to audio playback of a crow's distress call, played near a dead crow. The researchers wanted to know if they would also learn to associate dead crows — and threats to themselves — with specific predators.

The Big Picture: What the New Diet Guidelines Mean for You

Samantha Heller, a senior clinical nutritionist at New York University Langone Medical Center, thinks this approach is a good start. A healthy eating pattern is "an easier concept for people to understand," than, for example, delineating serving sizes, calorie counts and daily totals, Heller told Live Science. Elisabetta Politi, the nutrition director at the Duke Diet & Fitness Center in North Carolina, agreed.

More Young People Report Same-Sex Attractions

In particular, more men now say they are "mostly attracted to the opposite sex," rather than "only" attracted to the opposite sex compared to previous years, according to the survey from researchers at the Centers for Disease Control and Prevention. The new trend may result from greater societal acceptance of same-sex relationships, said Ritch Savin-Williams, a professor of developmental psychology at Cornell University who researches sexual orientation and behavior. This change, however, probably doesn't mean that more men now than in the past are feeling same-sex vibes, said Savin-Williams, who was not involved in the survey.

European scientists make last-ditch attempt to contact comet lander

By Victoria Bryan BERLIN (Reuters) - European scientists will send a command into space on Sunday to try to move and restore contact with the comet lander Philae that has fallen silent since the summer. After coming to rest in the shadows when it landed on a comet in November, Philae woke up in June as the comet approached the sun, giving scientists hope that the lander could complete some experiments that it had not done before its solar-powered batteries ran out.

Ancient Citadel Finds New Home in Apartment Building

A 3,400-year-old citadel near Israel's Mediterranean coast will soon be part of a modern, high-rise apartment building, according to the Israel Antiquities Authority (IAA). Architects are designing a building that will enclose the citadel, which will reside in the basement, said the IAA, which plans to formally announce the project tomorrow (Jan. 7) at a joint archaeological conference of the Northern Region of the IAA and the University of Haifa in Israel. Archaeologists uncovered the citadel during a recent excavation in the coastal city of Nahariya in northern Israel.

Strange New State of Hydrogen Created

By crushing Earth's lightest element with mind-boggling pressures, scientists have revealed an entirely new state of matter: phase V hydrogen. The squished hydrogen is a precursor to a state of matter first proposed in the 1930s, called atomic solid metallic hydrogen. And so, in crushing hydrogen at such high pressures, the physicists also got a glimpse of the inner atmosphere of a gas giant, where pressures reach millions of (Earth) atmospheres.
