Easter Island's ancient inhabitants weren't so lonely after all
23-Oct-14

20070422-AMX-TRAVEL_WLT-EASTERISLAND_1_MBy Will Dunham WASHINGTON (Reuters) - They lived on a remote dot of land in the middle of the Pacific, 2,300 miles (3,700 km) west of South America and 1,100 miles (1,770 km) from the closest island, erecting huge stone figures that still stare enigmatically from the hillsides. But the ancient Polynesian people who populated Easter Island, or Rapa Nui, were not as isolated as long believed. ...

Fixing 'Ebolanomics' in pursuit of vaccines and drugs
23-Oct-14

Scientists at the National Microbiology Lab in Winnipeg prepare an experimental Ebola vaccine for shipment to the World Health OrganizationBy Kate Kelland and Ben Hirschler LONDON (Reuters) - As researchers from Africa to China to America race to develop vaccines and treatments to fight Ebola, health experts are grappling with the economics of a disease that until this year had been off the drug industry's radar. Whether or not effective drugs come in time to turn around the world's worst epidemic of the virus ravaging three West African countries, the world will want stockpiles to protect against inevitable future outbreaks, experts say. ...






French entrepreneurs launch test to detect pork in food

An illustration picture shows a kit to test for the presence of pork in food for use by Muslims at the company Capital Biotech offices in Asnieres sur SeineBy Lucien Libert ASNIERES France (Reuters) - Two French entrepreneurs have launched a portable device to test for the presence of pork in food for use by Muslims who abide by dietary laws. With France's five million Muslims making up about eight percent of the overall population, the test, similar in size to a pregnancy test, aims to help consumers detect traces of pork not just in food, but also in cosmetics or medicines. The kit comes with a small test tube in which a food sample is mixed with warm water. ...






No Proof That 'Brain Training' Games Work, Some Experts Say
25-Oct-14

Sixty-nine scientists from around the world issued a statement this week, saying that there's no compelling scientific evidence supporting the claims that playing brain games may actually help people enhance their mental powers or overcome the effects of aging on the brain. The scientists didn't indicate which brain-training products are making misleading claims and which aren't. California-based Happy Neuron has nearly 11 million users and offers brain training programs to stimulate the main five cognitive functions, including memory, attention, language, and logical thinking. Rosetta Stone's Fit Brains offers games, designed by neuroscientists to help train crucial brain skills, the company says.



This Family Doesn't Sweat: Here's Why
25-Oct-14

People with a rare disorder called anhidrosis cannot produce sweat, and now a new study finds that the condition may be caused by a mutation in a single gene. Researchers studied a Pakistani family with several children who could not sweat. The researchers' analysis of the family members' genomes revealed that a genetic mutation may have caused the condition in this family. The mutation was in a gene, called ITPR2, that controls a basic cellular process in sweat glands, according to the researchers, led by Katsuhiko Mikoshiba, a molecular cell biologist at the RIKEN Brain Science Institute in Japan, and Niklas Dahl, a genetics researcher at Uppsala University in Sweden.



Man Recovers From Ebola in Germany After Routine Intensive Care
25-Oct-14

Man Recovers From Ebola in Germany After Routine Intensive CareOne man who contracted Ebola and even had further complications of the infection has now recovered after receiving routine intensive care at a hospital in Germany. The man's case suggests that even if patients do not have access to experimental Ebola drugs, health care workers can still help them recover from the disease, the doctors who treated him wrote in their report of the case. When it comes to treating Ebola patients, "It's supportive care, supportive care, supportive care," Schaffner told Live Science.

Skydiver Goes Supersonic in Record-Breaking 'Near-Space Dive'
24-Oct-14

Skydiver Goes Supersonic in Record-Breaking 'Near-Space Dive'In a harrowing plunge from the stratosphere, a Google executive broke the world record for the highest-altitude skydive today (Oct. 24). Alan Eustace, a senior vice president at Google, hit supersonic speeds as he fell from more than 25 miles (40 kilometers) above New Mexico, smashing the altitude record that Austrian daredevil Felix Baumgartner set two years ago with his famous Red Bull Stratos "space jump." Eustace's epic feat was orchestrated by the Stratospheric Explorer (StratEx) team at the Paragon Space Development Corporation. Eustace's body set off a sonic boom that could be heard by the recovery team on the ground, said Grant Anderson, CEO of Paragon. [See more amazing photos of StratEx's near-space dive] Eustace, 57, was already an experienced skydiver and pilot when he came to Paragon, Anderson said, but he required extra training and had to complete a series of increasingly difficult test dives before today's feat.

The Science Behind Renée Zellweger's New Face
23-Oct-14

Photographs of actress Renée Zellweger at the Elle magazine's Women in Hollywood awards this week, showing her dramatically different appearance, have sparked the Internet's interest. The 45-year-old actress looked almost unrecognizable to fans who know her best from her earlier movies such as "Jerry Maguire" and "Bridget Jones's Diary." But two cosmetic surgeons told Live Science that Zellweger's transformation could be the result of relatively minor procedures, as well as weight loss and normal aging. Zellweger looks so different because her most distinctive features are the ones that changed dramatically, said both Dr. Michael C. Edwards, the president of the American Society for Aesthetic Plastic Surgery, and Dr. Stuart Linder, a board-certified plastic surgeon in Beverly Hills, California. "That's what made her Renee Zellweger," Edwards told Live Science.

Science meets voodoo in a New Orleans festival of water
20-Oct-14

By Kathy Finn NEW ORLEANS (Reuters) - Perhaps no other city in the United States is as well-suited as New Orleans to wed a scientific discussion of environment with a celebration of the occult. That's exactly what unfolded on Saturday at "Anba Dlo," an annual New Orleans festival where prominent scientists joined with practitioners of the voodoo religion to look for answers to the challenges of dealing with water. In "The Big Easy," a low-lying Louisiana city devastated by Hurricane Katrina in 2005 and threatened by the BP oil spill of 2010, water is a subject nearly impossible to ignore. ...

Comet's Mars Flyby Sunday Has Scientists Abuzz
17-Oct-14

Comet's Mars Flyby Sunday Has Scientists AbuzzA comet's close shave with Mars this weekend could reveal some key insights about the Red Planet and the solar system's early days, researchers say. "On Oct. 19, we're going to observe an event that happens maybe once every million years," Jim Green, director of NASA's planetary science division, said in a news conference earlier this month. Siding Spring, whose core is 0.5 to 5 miles (0.8 to 8 km) wide, likely formed somewhere between Jupiter and Neptune about 4.6 billion years ago — just a few million years after the solar system began coming together. Many of the objects in the region where the comet was born were incorporated into newly forming planets, but a different fate awaited Siding Spring, researchers said: It apparently had a close encounter with one of these planets and was booted out into the Oort Cloud, a frigid comet repository at the very outer reaches of the solar system.
