Disgraced Japan researcher fails to replicate 'game changing' stem cell results
News ImageBy Elaine Lies TOKYO (Reuters) - A disgraced Japanese researcher has failed to replicate results hailed as a potential breakthrough in stem-cell treatment and efforts to do so will be abandoned, officials at her research institute said on Friday. The scandal involving the research, which detailed simple ways to reprogram mature cells back to an embryonic-like state, eventually led to the retraction of papers published in the influential journal Nature and tarnished the reputation of Japanese scientific research. ...

Europe recommends approval for first stem-cell therapy
LONDON (Reuters) - European regulators have recommended approval of the first medicine containing stem cells to treat a rare condition caused by burns to the eye. The European Medicines Agency said on Friday that Holoclar, from privately held Italian company Chiesi, had been given a green light for moderate to severe limbal stem cell deficiency due to physical or chemical burns. Left untreated, the condition can result in blindness. Holoclar is a living tissue product made from a biopsy taken from a small undamaged area of the patients cornea and grown in the laboratory using cell culture. ... Fri, 19 Dec 2014 08:08:22 -0500
Songbirds fly coop long before tornadoes arrive in Tennessee
News ImageBy Will Dunham WASHINGTON (Reuters) - You might want to be careful about who you call a birdbrain. Some of our feathered friends exhibit powers of perception that put humans to shame. Scientists said on Thursday that little songbirds known as golden-winged warblers fled their nesting grounds in Tennessee up to two days before the arrival of a fierce storm system that unleashed 84 tornadoes in southern U.S. states in April. The researchers said the birds were apparently alerted to the danger by sounds at frequencies below the range of human hearing. ...

Ebola Epidemic Continues in Africa, Despite Progress in Some Places
The Ebola epidemic in West Africa has undergone a dramatic change in the past several months, U.S. health officials said today (Dec. 22). There has been "real progress" in the fight against the deadly viral disease, but eliminating Ebola will require much more work, Dr. Tom Frieden, director of the Centers for Disease Control and Prevention, told reporters. "The response is inspiring, but the challenges are sobering," said Frieden, who just returned from a trip to the region of West Africa affected by the outbreak. In Guinea, officials with Doctors Without Borders said they'd seen "the scariest thing I've heard," Frieden said: For the first time since the outbreak began, there were not enough beds for sick patients in treatment centers in the capital city of Conakry.

Dj Vu All Over Again: This Man Relived Every New Moment
Trapped in a time loop: That's how one man felt because of his recurring dj vu episodes. Unlike the vague, fleeting sensation most people experience in dj vu, his episodes were persistent and long. "Rather than simply the unsettling feelings of familiarity which are normally associated with dj vu, he complained that it felt like he was actually retrieving previous experiences from memory, not just finding them familiar," the researchers said. What made the case even more peculiar was that the man didn't suffer from any of the neurological conditions previously reported in people who experience frequent dj vu episodes.

'Illusion Coatings' Are Like Futuristic Camouflage
News ImageThis means "the act of cloaking would prevent an enclosed antenna or sensor from communicating with the outside world," lead study author Zhi Hao Jiang, an electrical engineer at Pennsylvania State, said in a statement. These were covered with patterns of copper stripes that interacted with the composite material to scatter radio waves in a very precise way. Depending on the copper patterns used, the researchers could make a copper antenna or sensor look like silicon or Teflon when it was scanned by radio waves. "The coatings we invented can still allow for the electromagnetic communication between the coated object and the outside world," said study co-author Douglas Werner, an electrical engineer at Pennsylvania State University.

Ursid Meteor Shower Peaks Tonight: How to See It
News ImageThe Ursid meteor shower peaks tonight, and it should be a great show. When skywatchers think of meteor showers during the month of December, the Geminid shower (which peaked earlier this month) usually comes to mind. Even if you can't see tonight's meteor shower due to light pollution or bad weather, you can still catch the Ursids online thanks to the Slooh Community Observatory.

Voyager 1 Rides 'Tsunami Wave' in Interstellar Space
News ImageIt turns out that sailing through interstellar space isn't so peaceful. NASA's Voyager 1 spacecraft the only object made by humans to reach interstellar space might still be caught what scientists have described as a cosmic "tsunami wave," a shock wave that first hit the probe in February, according to new research. You canhear the eerie interstellar vibrations in a video, courtesy of NASA. "Most people would have thought the interstellar medium would have been smooth and quiet," study researcher Don Gurnett, professor of physics at the University of Iowa, and the principal investigator of Voyager 1's plasma wave instrument, said in a statement from NASA.

Back to the future: Scientists want 'rewilded' crops to boost agriculture
By Chris Arsenault ROME (Thomson Reuters Foundation) - Scientists should "re-wild" food crops by inserting lost genetic properties of ancient, edible plants in order to boost agricultural output for a growing population, a new study said. Important properties of wild plants, including varieties of wheat and rice, have been unintentionally lost during thousands of years of breeding. When humans first domesticated wheat around 7500 BC, farmers chose to use seeds based on a few selected traits, particularly their yields. ... Tue, 16 Dec 2014 12:06:15 -0500
NASA Probe Piecing Together How Mars' Atmosphere Escapes to Space
News ImageA NASA spacecraft that recently arrived in orbit around Mars is already helping to solve a Martian mystery. Scientists are using the space agency's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft to gather more data about how Mars' atmosphere bled molecules out into space over time. The agency released early results from the probe today (Dec. 15), showing how the continuous stream of particles emanating from the sun, called the solar wind, bury more deeply into the Martian atmosphere than scientists had previously thought. "Over the course of the full mission, we'll be able to fill in this picture and really understand the processes by which the atmosphere changed over time," Bruce Jakosky, MAVEN principal investigator with the Laboratory for Atmospheric and Space Physics at the University of Colorado, said in a statement.

Why Birds Don't Have Teeth
News ImageThe common ancestor of all living birds sported a set of pearly whites 116 million years ago, a new study finds. In the study, researchers looked at the mutated remains of tooth genes in modern birds to figure out when birds developed "edentulism" an absence of teeth. Ancient birds have left only a fragmented fossil record, but studying the genes of modern birds can help clarify how the bird lineage has changed over time. "DNA from the crypt is a powerful tool for unlocking secrets of evolutionary history," Mark Springer, a professor ofbiology at the University of California, Riverside and one of the study's lead researchers, said in a statement.
