- Google executive sets new stratosphere skydive world record
(Reuters) - A skydiving Google executive is safely back on Earth after jumping out of a giant balloon floating in the stratosphere more than 25 miles (40 km) above New Mexico, a feat that broke the sound barrier and shattered a world altitude record. Alan Eustace, a senior vice president at the Mountain View, California-based company, was lifted up 135,890 feet (41,419 meters) by an enormous balloon shortly before dawn on Friday, the Paragon Space Development Corp said. ...
- SpaceX Dragon capsule splashes down in Pacific Ocean
(Reuters) - A Space Exploration Technologies Dragon cargo ship ended a monthlong stay at the International Space Station on Saturday and splashed down on schedule in the Pacific Ocean near Mexico. Reid Wiseman and Barry Wilmore, astronauts with U.S. space agency NASA, used the station’s robotic crane to release the capsule, built and operated by California-based SpaceX, as the company is known, at 9:57 a.m. EDT (1357 GMT) as the two vehicles soared 260 miles (418 km) over the northwest coast of Australia. “Dragon is free,” mission commentator Rob Navias said during a live broadcast on NASA TV. ...
- Easter Island's ancient inhabitants weren't so lonely after all
By 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. ...
- Old, cold and bold: Ice Age people dwelled high in Peru's Andes
By Will Dunham WASHINGTON (Reuters) - In a bleak, treeless landscape high in the southern Peruvian Andes, bands of intrepid Ice Age people hunkered down in rudimentary dwellings and withstood frigid weather, thin air and other hardships. Scientists on Thursday described the world's highest known Ice Age settlements, two archaeological sites about 2.8 miles (4.5 km) above sea level and about 12,000 years old packed with artifacts including a rock shelter, stone tools, animal bones, food remnants and primitive artwork. ...
- Fixing 'Ebolanomics' in pursuit of vaccines and drugs
By 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. ...
- No Proof That 'Brain Training' Games Work, Some Experts Say 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 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
One 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.
- Huge Solar Flare Erupts from Biggest Sunspot in 24 Years (Photos)
The solar flare occurred Friday afternoon, reaching its peak at 5:41 p.m. EDT (2141 GMT), and triggered a strong radio blackout at the time, according to the U.S. NASA's sun-watching Solar Dynamics Observatory captured stunning video of the huge solar flare. The flare erupted from a giant active sunspot known as AR 12192 and was classified as an X3.1-class solar storm — one of the most powerful types of solar storms on the sun — but it is not the first time the sunspot has made its presence known. "This is the fourth substantial flare from this active region since Oct. 19," NASA spokesperson Karen Fox wrote in a status update.
- Splashdown! SpaceX's Dragon Cargo Spaceship Returns to Earth
A private SpaceX Dragon capsule dropped into the Pacific Ocean today (Oct. 25), returning almost 2 tons of cargo and science experiments to Earth from the International Space Station. The unmanned Dragon was released from the space station at 9:57 a.m. EDT (1357 GMT). Its parachute-guided splashdown west of Baja California, which was confirmed around 3:38 p.m. EDT (1938 GMT), marked an end to SpaceX's fourth of 12 unmanned delivery missions to the space station for NASA under a $1.6 billion contract. Dragon had been attached to the orbiting lab for a little more than month.

- The Science Behind Renée Zellweger's New Face 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 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
A 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.
- Are we there yet? Scientists prepare for change of epoch
By Emma Anderson BERLIN (Reuters) - Scientists from around the world met this week to decide whether to call time on the Holocene epoch after 11,700 years and begin a new geological age called the Anthropocene - to reflect humankind's deep impact on the planet. For decades, researchers have asked whether humanity's impact on the Earth's surface and atmosphere mean we have entered the Anthropocene - or new human era. ...
- 25 Years After Loma Prieta, Earthquake Science Is Transformed
The Oct. 17, 1989, Loma Prieta earthquake was America's first widely-shared natural disaster. The TV crews at San Francisco's Candlestick Park soon turned their cameras on the ravaged city, and frightening images poured in of people trapped in crumpled freeways, burning buildings and toppled storefronts. The magnitude-6.9 Loma Prieta earthquake, centered below the Santa Cruz Mountains, shook much of central California. The resulting damage ultimately revitalized San Francisco, with a new waterfront replacing the demolished Embarcadero Freeway and a $30 billion investment from public and private organizations for redevelopment and seismic upgrades.
- Saturn moon may have 'life-friendly' underground ocean - scientists By Irene Klotz CAPE CANAVERAL Fla. (Reuters) - Saturn’s battered moon Mimas may have a thin global ocean buried miles beneath its icy surface, raising the prospect of another "life-friendly" habitat in the solar system, scientists said on Thursday. An underground ocean is one of two explanations for why the 400-mile (250-km) diameter moon wobbles as it orbits around Saturn, scientists using data from NASA’s Cassini spacecraft said. The other possibility is that Mimas has an oblong or rugby ball-shaped core. Follow-up measurements should provide more answers, the scientists said. ...
- Female orgasm: battleground of science? By Kathryn Doyle NEW YORK (Reuters Health) - Hapless lovers are not the only ones who get lost down there: even sexologists can’t agree on what’s what, and where, among women's female parts. At least, that’s according to a father-daughter team of researchers in Italy, Drs. Vincenzo and Giulia Puppo. In a new review October 6 in Clinical Anatomy, Vincenzo, of the Italian Center of Sexology in Bologna, and Giulia, a biologist at the University of Florence, point out some problems with some of newer anatomical and physiological terms researchers have been using since the mid-1990s. ...

- New Exotic Particle Could Help Explain What Holds Matter Together
A new exotic particle has been hiding out amidst the gobs of data collected by the world's largest atom smasher, physicists have discovered. The new particle, called Ds3*, is a meson — a type of unstable particle made of one quark and one antiquark. They're held together by the strong interaction, or strong force, that is one of the four fundamental forces in nature. To find the new particle, Tim Gershon, a professor of physics at the University of Warwick in the United Kingdom, and his team used the Dalitz plot analysis.
- New Tech Helps Pilots Navigate Dangerous Volcanic Ash Plumes
New technology to detect volcanic ash that threatens airplanes could help prevent a repeat of the air traffic chaos that followed a 2010 volcanic eruption in Iceland. With satellites, scientists can detect tiny ash particles, but predicting where aircraft can safely fly is still a major hurdle. "The key issue for us is to develop an integrated monitoring and response system for future volcanic crises that can be used to respond quickly in the event of the formation of an ash cloud from Iceland," Hans Schlager, head of the Institute of Atmospheric Physics at the German Aerospace Center, said in a statement. Ash particles are jagged and sharp.
- Rattlesnake repertoire boosts snake-like robot's skills By Will Dunham WASHINGTON (Reuters) - How do you make a better snake robot? You study snakes, of course. Researchers on Thursday said they conducted experiments to learn precisely how sidewinder rattlesnakes are able to climb sandy hills, then applied the reptiles' repertoire to an existing snake robot so it could do the same thing. The study, published in the journal Science, is an example of how scientists are applying knowledge of biology to improve technology. ...
- Scientists find lung cancer can lie hidden for 20 years By Ben Hirschler LONDON (Reuters) - Lung cancer can lie dormant for more than 20 years before turning deadly, helping explain why a disease that kills more than 1.5 million a year worldwide is so persistent and difficult to treat, scientists said on Thursday. Two papers detailing the evolution of lung cancer reveal how after an initial disease-causing genetic fault -- often due to smoking -- tumour cells quietly develop numerous new mutations, making different parts of the same tumour genetically unique. ...
- Bright Idea: How Blue LEDs Changed the World
This year's Nobel Prize in physics was awarded to three Japanese scientists for the invention of blue light-emitting diodes (LEDs), a technology that has touched society in innumerable ways and enabled technologies that Americans take for granted every day. "Blue LEDs made possible the white-light LEDs you can buy in a hardware store and put in your house," said H. Frederick Dylla, executive director and CEO of the American Institute of Physics in College Park, Maryland. Without blue LEDs, the world wouldn't have backlit smartphones, TV and computer LCD screens, Blu-ray players, many forms of lighting and countless other technological marvels. Blue LEDs, in combination with red and green LEDs (which had been discovered previously), make it possible to produce white light.
- How to Turn Your Smartphone Into a Cosmic-Ray Detector
It's called the Distributed Electronic Cosmic-Ray Observatory (DECO), and unlike the huge, multimillion-dollar particle detectors housed in labs, DECO allows smartphone owners to turn their phone into a pocket-size cosmic-ray particle detector by downloading two apps and sticking a piece of duct tape over the camera lens to block out light particles. "The apps basically transform the phone into a high-energy particle detector," Justin Vandenbroucke, a physics professor at the University of Wisconsin-Madison and creator of the apps, said in a statement. Cosmic rays are still a mystery to astrophysicists. Waves of cosmic rays are constantly breaking against the Earth's atmosphere.

- High risk Ebola could reach France and UK by end-October, scientists calculate
By Kate Kelland Scientists have used Ebola disease spread patterns and airline traffic data to predict a 75 percent chance the virus could be imported to France by October 24, and a 50 percent chance it could hit Britain by that date. Those numbers are based on air traffic remaining at full capacity. Assuming an 80 percent reduction in travel to reflect that many airlines are halting flights to affected regions, France's risk is still 25 percent, and Britain's is 15 percent. ...
