|  Moon Surprise: Lunar Craters Are Bigger on Near Side  | "When we look at the maps of both hemispheres, we realize there are more big basins on the near side than on the far side," said Katarina Miljkovic of the Institute de Physique du Globe de Paris, lead author of the new moon study published in the Nov. 8 issue of the journal Science. Using data gathered by NASA's Gravity Recovery and Interior Laboratory (GRAIL) spacecraft, Miljkovic and her colleagues ran computer simulations to model the effects of long-ago impacts on the moon's crust. Instead, the malleable surface of the near side was able to expand, creating larger basins and displacing more of the crust, even if the impactor was not necessarily huge, Miljkovic found. In light of this new work, however, ideas about that period, known as the "late heavy bombardment," might need to be altered, Miljkovic said.
| Read More » Antarctic Glacier Flow Controlled by Speed Bumps Below  | Beneath Antarctic glaciers sliding quickly toward the sea, researchers now find that stripes of extremely high friction exist that help control the rates at which giant chunks of ice flow into the ocean. As climate is changing globally, scientists concerned about melting ice caps and subsequent rising sea levels have focused on ice streams near the margins of the Antarctic Ice Sseet, the largest mass of ice on Earth. The rates at which these ice streams drain to the sea vary and are controlled by factors that have largely been unclear to scientists. Researchers had known that the more firmly ice sheets are stuck to the bedrock beneath them, the more slowly they will move, but much else was uncertain.

"We were literally dumbfounded when we saw it," astronomer David Jewitt with the University of California at Los Angeles, said in a statement. In September astronomers used the sharp-eyed orbiting Hubble telescope to zero in on the object, located in the main asteroid belt between Mars and Jupiter. Not only is the asteroid sporting six tails, follow-up observations 13 days later showed it had changed shape.

If trans fat are not GRAS, they would become illegal food additives, unless food companies can prove that they are not harmful to health, which would be a challenge, Michael R. Taylor, the FDA's deputy commissioner for foods and veterinary medicine, told the New York Times. Before the decision is finalized, the FDA is seeking public comment for 60 days to hear from the food industry and other experts to determine how long it would take food manufacturers to phase out trans fats, and how the change would impact small businesses. Trans fats are produced when hydrogen is added to vegetable oil to make it more solid, and companies began adding the ingredient to processed food in the 1950s to lengthen the shelf-life and flavor stability of their products, the FDA said.

Chris Christie next to the headline, "The Elephant in the Room." The recently re-elected governor has famously struggled with his weight, which topped 350 lbs. (159 kilograms) before he had gastric-band surgery in February. With the help of a British doctor, he lost about 60 lbs. (27 kg) at one point, but struggled to keep the weight off throughout his life.

The Bank of Canada began circulating the new $5 note on Thursday (Nov. 7), seven months after debuting the space-inspired design aboard the space station. Recently-retired Canadian astronaut Chris Hadfield, who in April revealed the first of the blue-color bills while serving as commander of the station's Expedition 35 crew, came to the Canadian Space Agency's Quebec headquarters to help launch the polymer currency. The new bill features the Canadian-built Canadarm2 and Dextre, robotic arms and manipulators that were used to build and now maintain the space station and which have gone on to symbolize Canada's ongoing contribution to the international space program.
| Read More » No Proof That Cosmic Rays Cause Global Warming, Study Says  | As the Intergovernmental Panel on Climate Change concluded in September, it is "extremely likely" that human activities have caused most of the warming of the planet's surface since the 1950s. One of the more persistent is that global warming is caused by cosmic rays and changes in levels of solar radiation. As the theory goes, cosmic rays — which are thought to emanate from supernovas, explosions of distant stars — can increase the number of clouds in Earth's atmosphere by filling the atmosphere with charged particles, upon which water vapor condenses. However, during times of increased solar radiation, fewer cosmic rays enter the atmosphere, as they are deflected by charged particles spit out from the sun.

| Read More » Russian Fireball Fallout: Huge Asteroid Numbers Raise Stakes of Impact Threat  | A new analysis of the Russian meteor explosion that injured more than 1,000 people in the city of Chelyabinsk this past February estimates that similar impacts occur about seven times more often than previously thought. That means there could be more than 20 million near-Earth asteroids roughly 62 feet (19 meters) wide — the size of the Chelyabinsk object — rather than three or four million, scientists say, adding to the Russian meteor explosion's importance as a teachable moment. "It has attracted more attention to the threat," Lindley Johnson, program executive for NASA's Near-Earth Object (NEO) Observations Program, said of the Chelyabinsk event in a teleconference with reporters Wednesday (Nov. 6). The Russian meteor caught scientists and citizens of Chelyabinsk by surprise, exploding without warning on Feb. 15.

"The liver has the ability to regrow itself," said Keith Murphy, CEO of Organovo. That represents a huge leap from the company's previous benchmark in April, when it showed that its liver slices could maintain liver function for just over five days. The results suggest that the 3D-printed liver slices function about as normally as a typical human liver. Read More » UN draft stresses risk of global warming, from economy to health  | By Environment Correspondent Alister Doyle OSLO (Reuters) - Global warming poses a mounting threat to health, economic growth, crops and water supplies, according to a draft report by top scientists that puts unprecedented emphasis on the risks of a changing climate. A leaked 29-page draft by the U.N. Intergovernmental Panel on Climate Change (IPCC), about the impacts of rising temperatures and due for release in March 2014, mentions "risk" 139 times against just 41 in its last assessment in 2007. The increased stress on risk may make the case for cutting greenhouse gas emissions clearer both to policymakers and the public by making it sound like an insurance policy for the planet, analysts say. Many governments, meeting in Warsaw from November 11-22 for U.N. talks on climate change, have long pleaded for greater scientific certainty before making billion-dollar investments in everything from flood barriers to renewable energies.

Researchers with the Wildlife Conservation Society (WCS) made the find while surveying white-lipped peccaries in Brazil's Cerrado plateau, a vast savanna region, in 2009. "Since we often work in remote locations, we sometimes make surprising discoveries, in this case, one that appears to be important for our understanding of human cultural history in the region," Alexine Keuroghlian, a researcher with WCS's Brazil program, said in a statement.

A device that mimics the squeezing action of the human heart has been used to pump urine into a microbial fuel cell, which could power robots that convert the waste into electricity. "In the future, we hope the robots might be used in city environments for remote sensing," where they could help to monitor pollution, said study researcher Peter Walters, an industrial designer at the University of the West of England.

Why Scientists Really Don't Know Whether drinking small amounts of alcohol during pregnancy affects the mind of the unborn child is a topic of much current research, and now new findings suggest there are key lifestyle differences between pregnant women who sip and those who don't that most research on the topic hasn't taken into account. Looking at data gathered on more than 63,000 pregnant women in Denmark, the study researchers found that women who said they drank a small amount of alcohol during their pregnancies tended to be healthier, in many ways, than the women who said they completely abstained from alcohol upon learning they were pregnant. "Women who drink and women who do not drink in pregnancy are very different on a large number of characteristics," said study researcher Janni Niclasen, a psychology researcher at the University of Copenhagen. Such women may have the mind-set that, "I'm doing everything else right, so the occasional drink may not hurt," or that these women, who also tend to be well educated, think, "I did all right, and so will my child," Niclasen speculated.

The boy remains cancer-free, and peanut-allergy free, following a bone marrow transplant to treat his acute lymphoblastic leukemia, said the doctors who presented his case today (Nov. 8) at the annual meeting of the American College of Allergy, Asthma and Immunology (ACAAI) in Baltimore. This two-for-one cure is not unprecedented, but is rare and provides new insights into the nature of allergies and the workings of the immune system. Public awareness of peanut allergies is especially high; Read More » Bullying Syndrome? How Maltreatment Affects Health  | But while the common images of bullying — kids shoved against lockers, and "mean girls" slinging gossip — emphasize bullying as a social ill, medical professionals increasingly see bullying as a public health issue. Dr. Jorge Srabstein, medical director of the Clinic for Health Problems Related to Bullying at the Children's National Medical Center (CNMC), has long emphasized bullying's very real physical and psychological health effects. "Bullying is linked to a wide range of health issues, both physical and emotional symptoms," said Srabstein, who has both studied the issue and treated thousands of children in his practice. Instead, they get headaches accompanied by anxiety, stomachaches and depression, Srabstein said.

But that's exactly what a team of researchers discovered along the coast of South Carolina. The new species looks virtually identical to the scalloped hammerhead, but is genetically distinct, and contains about 10 fewer vertebrae, or segments of backbone, new research shows. The new species, named the Carolina hammerhead (Sphyrna gilbert), gives birth to shark "pups" in estuaries near the shore off the Carolinas, according to a study published in August in the journal Zootaxa.
