Sun Exposure Reduces Blood Clot Risk While tanning has been discouraged in recent years due to the link between sun exposure and skin cancer, researchers say the sun’s rays are not entirely bad for the health. According to the results of a new Swedish study, women who suntan have about 30 percent lower risk of suffering blood clots. Sun exposure stimulates vitamin D production in the body, and researchers believe that the vitamin plays a role in preventing blood clots. The study authors stress that though daily sun exposure can be beneficial, people should always take care to avoid sunburns   LETS BEGIN IN 2010 ID: 879439 ·  |

Scientist Track Asteroid's Impact with Earth For the first time, scientists tracked an asteroid on a collision course with Earth, observed as it crashed into Earth's atmosphere and exploded, and collected surviving fragments from the crash zone. The asteroid, dubbed 2008 TC3, disintegrated about 23 miles (37 kilometers) over the Nubian Desert of Sudan last October, releasing the energy of one to two kilotons of trinitrotoluene, or TNT. The fragments recovered from the crash site are a rare type of meteorite known as ureilite. Observations of 2008 TC3 before impact showed that it belonged to the F-class, providing scientists with the first direct evidence that ureilite meteorites originate from F-class asteroids.

Biological Basis for Kids' Candy Cravings Children across cultures have shown a preference for higher levels of sweetness in their foods than adults, and researchers have wondered whether this preference is the result of biological or sociological factors. To investigate this phenomenon, researchers gave 143 children between the ages of 11 and 15 sugary drinks with increasing levels of sweetness. They found that children who had the highest levels of a biomarker for bone growth in their urine were most likely to prefer the sweetest drinks and speculate that the preference for sweet things may be the body’s response to an increased need for calories during growth LETS BEGIN IN 2010 ID: 880876 · |

Crew Settles in for 105-Day Simulated Mars Journey Six European menâ€â€four Russians, a German, and a Frenchmanâ€â€entered a cramped capsule on Tuesday to begin a 105-day simulation intended to test the men’s ability to endure the isolation, stress, and fatigue of a mission to Mars. During the simulation, the volunteers will eat dehydrated food, breathe recycled air, and face specially designed emergencies and problems such as 20-minute communication delays with flight control as the radio signals "travel" to Earth and back. Scientists outside the module will monitor the crew via video cameras, watching for stress and tension among crewmembers. LETS BEGIN IN 2010 ID: 881258 · |

CT Scan Reveals Two-Faced Nefertiti According to German researchers, there is more to the 3,300-year-old bust of ancient Egypt’s Queen Nefertiti than meets the eye. The team uncovered a second, hidden face within the bustâ€â€a detailed carving in the limestone core that differs from the external stucco faceâ€â€after an imaging procedure known as a computed tomography (CT) scan allowed them to study artifact’s stone core. A comparison of the two versions revealed that the sculptor enhanced the cheekbones, smoothed creases around the mouth, and fixed a slight bump on the ridge of the nose of the visible, stucco visage LETS BEGIN IN 2010 ID: 881874 · |

Death Toll Climbs in Italy Quake A powerful earthquake in central Italy caused entire blocks of buildings to collapse early Monday morning as residents slept, killing and trapping many under the rubble. Rescue efforts in the mountain city of L'Aquila as well as neighboring towns are ongoing following the powerful quake, the country's deadliest in nearly three decades, with residents and rescuers using their bare hands to clear the debris. More than 100 people were killed and 1,500 injured, and the death toll is likely to rise as more victims are extracted from the rubble LETS BEGIN IN 2010 ID: 883076 · |

Sherpa to Scale Everest for 19th Time Forty-nine-year-old Apa Sherpa has summitted Mount Everest a record 18 times, and he hopes to conquer it once again this spring. Apa has said that since his first success in 1990, he has encountered less and less snow on the mountain’s summit. He hopes this trip will bring attention to the impact that climate change is having on the Himalayas. He also plans to educate other climbers about the negative impact human waste has on Everest by collecting some of the garbage left behind by decades of careless mountaineers and bringing it off the mountain with him LETS BEGIN IN 2010 ID: 884112 · |

Swedish Internet Traffic Drops with Piracy Law According to a Swedish company that measures Internet traffic in and out of the country, Internet traffic dropped 33% on the day the country’s new anti-piracy law came into effect. The law, which is based on the European Union's Intellectual Property Rights Enforcement Directive, allows copyright holders to force Internet service providers to furnish them with the Internet Protocol (IP) addresses of computers sharing copyrighted material. Though the new anti-piracy law has clearly been a deterrent for many of Sweden’s Internet users, it remains to be seen how long these effects will last LETS BEGIN IN 2010 ID: 884291 · |

Extremely Rare Shark Caught and Eaten A megamouth shark, a shark so rare that the International Union for Conservation of Nature lists the species as "data deficient," was caught by fishermen in the Philippines and then cooked as part of a local delicacy. The 13-ft (4-m), 1,100-lb (500 kg) specimen was only the 41st megamouth ever found. The species, discovered in 1976, is so unusual that scientists initially had to create a new family and genus to classify it. Representatives of the World Wildlife Fund, an international conservation organization, say the catch highlights the incredible biodiversity of the area and the importance of continuing to protect the region’s marine ecosystem.

Promotions Can Be Harmful to Health Researchers testing the hypothesis that an improvement in job status leads to better health found instead that promotions can actually produce the opposite results. It had previously been assumed that an improvement to a person’s job status would directly result in better health because the promotion would lead to an increased sense of self-worth, but this study found no evidence that physical health improves after promotion. Instead, researchers concluded that promotions actually produce 10 percent more mental strain and leave employees up to 20 percent less time to visit the doctor in the event of illness.

Stem Cells Stimulate Egg Development in Adult Mice Scientists say that infertile female mice were able to reproduce after being implanted with female germline stem cells extracted from the ovaries of other mice. According to the researchers, 80 percent of the mice that had the cultured stem cells implanted in their ovaries produced offspring after natural mating. It is widely accepted in scientific circles that that the production of eggs, known as oocytes, stops before birth for most mammalian species. This research could therefore have important implications in the treatment of female infertility LETS BEGIN IN 2010 ID: 886087 · |

Bacteria Thrive Beneath Arctic Glacier For years, scientists have been fascinated by the flow of blood-red water from the side of Taylor Glacier, a feature called Blood Falls. Analysis of the rust-colored outflow revealed that iron compounds give the fluid its reddish hue, but how the iron actually gets to the surface of the glacier remained a mystery until researchers finally obtained a sample of marine brine trapped about a quarter of a mile (400 m) beneath the glacier. The sample revealed that microorganisms are thriving in the cold, salty, subglacial pool and use iron leached from the glacial bedrock to complete a series of energy-producing metabolic reactions.

Forests Could Become CO2 Source Plants both absorb and emit carbon dioxide (CO2), and while healthy forests take in far more greenhouse gasses than they let off, this stored carbon is released when they become damaged or die. Scientists believe that if Earth’s surface warms by another 3.6° F (2° C), forests that today take in a quarter of the CO2 released into the atmosphere could actually become a source of the gas. The release of CO2 from damaged forests could then accelerate the global warming process. Since the mid-19th century, human activities have caused global temperatures to rise about 1.3° F (0.7° C).

Hijacking in Jamaica Ends with Gunman's Capture A troubled 20-year-old man named Stephen Fray hijacked a CanJet plane parked in Sangster International Airport in Montego Bay, Jamaica, late Sunday night. More than 150 passengers and eight crew members were on board at the time, but he allowed almost everyone to disembark shortly after seizing the plane. His family was brought in to help negotiate the release of the remaining hostages, but when communication broke down, Jamaican authorities made the decision to storm the plane and end the standoff. The hijacker was taken into custody early Monday morning. LETS BEGIN IN 2010 ID: 886990 · |

Video Game Addiction May Be a Growing Problem According to a recent survey of nearly 1,200 American youths between the ages of eight and 18, nearly one in 10 children who play video games may be developing an addiction to the activity. According to researchers, about 8.5 percent of video game players exhibited "pathological patterns of play," a designation reserved for gamers who displayed at least six of 11 clinical symptoms showing damage to family, social, school, or psychological functioning. The most typical symptom was skipping household chores in order to play video games, but many of those surveyed also said they played to escape problems and took time away from homework and school studies to play.

Fossil Ancestor of Seal Found in Arctic The fossil of a previously unknown web-footed carnivore that looks like a cross between a seal and an otter may help explain how seals developed from land-based mammals. The animal, dubbed Puijila darwini, was likely adept at both swimming and walking on land and lived about 20 to 24 million years ago. The creature was a member of the pinniped family, a suborder of aquatic mammals that includes seals and walruses. Its feet and other anatomical features provide scientists with evidence of the animal’s land-to-sea transition, showing the beginning stages of its development of flippers and other marine adaptations.

Cache of Egyptian Mummies Unearthed Archaeologists excavating the area around Egypt’s Lahun pyramid have discovered a cache of dozens of mummies, brightly painted sarcophagi, and ancient tombs. Some of the tombs date back 4,000 yearsâ€â€to the time of Egypt’s 12th dynastyâ€â€and could give researchers insight into the development of ancient Egyptian funerary architecture and traditions. Prayers to help the deceased are inscribed on several of the coffins, while others bear colorfully painted images of their occupants. A funerary chapel with an offering table, masks, pottery, statues, and protective amulets was also found at the site. LETS BEGIN IN 2010 ID: 889634 · |
