4:30 PM | EPA Should Address Natural Gas Leaks
Since the great rush for natural gas in the United States, environmentalists have been torn on the fuel's benefits for alleviating climate change. It produces less carbon dioxide emissions than coal for electricity or gasoline and diesel for fuel, but even a small amount of natural gas release -- which is essentially methane -- packs a greenhouse gas punch about 30 times more powerful than the same amount of carbon dioxide.

3:00 PM | Velvet Improves Older Adults' Well-Being
It's no surprise that soft materials are more pleasing to the touch than rough ones, but a recent study found that they can actually improve the cognitive and emotional skills of older adults. In the research, published in the October 2012 issue of Geriatrics and Gerontology International , participants were divided into three groups, each of which completed twice-weekly activities that involved working with either a piece of velvet, canvas or Velcro. After 10 weeks, participants in the […]

1:00 PM | Scientists Decipher the Healing Powers of Placebos (preview)
Back in the 18th century, German physician Franz Mesmer peddled a concept called animal magnetism. Creatures contain a universal fluid, he asserted, that when blocked in flow, caused sickness. Mesmer used magnetized objects to redirect that flow in patients, initiating unusual body sensations, fainting, vomiting or violent convulsions that ended in profound salubrious effects. [More]

By Timothy GardnerWASHINGTON (Reuters) - The Obama administration is inching ahead with a plan that would allow wastewater from fracking to be shipped on barges, fueling a debate whether it is safer than other transportation modes or risks polluting drinking water.The Coast Guard last month quietly sent to the White House's Office of Management and Budget a proposal to allow the barging of fracking wastewater.

11:00 PM | Dark Matter Signal Possibly Registered on International Space Station
A $2-billion particle detector mounted on the International Space Station has registered an excess of antimatter particles in space, the experiment’s lead scientist announced April 3. That excess could come from fast-spinning stellar remnants known as pulsars and other exotic, but visible sources within the Milky Way galaxy. Or the antiparticles might have originated from the long-sought dark matter, the hypothetical massive particles that constitute some 27 percent of the universe. […]

9:40 PM | When It's Brains, It Pours ($$$$$): Obama's Big (Neuro) Science Project
It was an anti-climax: the President of the United States clocking in after The New York Times had already spilled the beans about his big brain program, a centerpiece of the administration's second-term, legacy-making efforts in the science arena. After the Times article, everyone had, for weeks, written, speculated, chewed over and made preparations for the Imminent Big Thing (an Apollo program or Human Genome Project of the Mind), to which an oblique but cryptic mention had popped out […]

The last time the Earth enjoyed greenhouse gas levels like those of today was roughly 4 million years ago, during an era known as the Pliocene. The extra heat of average temperatures as much as 4 degrees Celsius warmer turned the tropical oceans into a nice warm pool of bathwater, as noted by new research published in Nature on April 4.

Between is a state of being for Archaeopteryx. No mere transitory stage, this; even at maturity, with greying feathers and dulled claws, the Archaeopteryx is always between, with attributes that may serve some future incarnation but now are more hindrance then help.No matter. When between is your birthright, you learn to live with it. Predators on the ground, predators in the air, and between them is Archaeopteryx, sometimes falling prey to one, sometimes to another, destined to outpace them […]

9:14 PM | Vintage Dinosaur Art: The How and Why Wonder Book of Dinosaurs
Very, very occasionally, when the planets in the Solar System arrange themselves in an apparently haphazard, but in fact entirely co-ordinated and precise pattern, a truly superb and genuinely vintage dinosaur book appears, like a distant, glittering jewel, over the eBay horizon. (The rest of the time, I buy any old rubbish from the '80s and you get lousy filler posts.) The How and Why Wonder Book of Dinosaurs is just such a book. It's also no less than the first dinosaur book owned by a […]

4:47 PM | Citizen Science: Are you brave enough to venture to Earth´s Core?
Since old times people – especially geologists – speculated about the interior of Earth. The Italian poet Dante Alighieri (1265-1321) imagined an allegoric center of the Earth: a frozen wasteland, not reached by the divine light, where Lucifer is entrapped in eternal ice. The French Sci-Fi author Jules Gabriel Verne (1828 – 1905) based “A [...]

4:50 PM | Happy Easter with a (fake) Dozen Dinosaur Eggs
Roy Chapman Andrews was not only an intrepid explorer and palaeontologist, but also a gifted promoter. The Central Asiatic Expeditions in search of fossils of mammals and dinosaurs were accompanied by movie cameras to film their work. As the conditions were most time prohibitive -sandstorms, burning sun and arid climate - many scenes showing the discovery and excavation of fossils were probably staged after the real work had be done. Many photos of the expedition-photograph John B. Shackelford […]
