Light pulses take a quantum walk
Nanopower: Avoiding electrolyte failure in nanoscale lithum batteries
Tourists who drift aimlessly during a sightseeing tour are moving randomly - just like electrons that move from one atom to the next. To obtain a better understanding of these random motions it is often useful to reduce their complexity. Physicists do this by simulating random walks. These simulations can bring new insights in the quantum world as well. Researchers at the Max Planck Institute for...
New findings awaken age-old anesthesia question
(PhysOrg.com) -- It turns out you can be too thin -- especially if you're a nanoscale battery. Researchers from the National Institute of Standards and Technology, the University of Maryland, College Park, and Sandia National Laboratories built a series of nanowire batteries to demonstrate that the thickness of the electrolyte layer can dramatically affect the performance of the battery,...
NIST releases technical guidance for evaluating electronic health records
(PhysOrg.com) -- Why does inhaling anesthetics cause unconsciousness? New insights into this century-and-a-half-old question may spring from research performed at the National Institute of Standards and Technology. Scientists from NIST and the National Institutes of Health have found hints that anesthesia may affect the organization of fat molecules, or lipids, in a cells outer...
Orion Crew capsule targeted for 2014 leap to high orbit
An important aspect of any product is how easily someone can use it for its intended purpose, also known as usability. Electronic health records (EHR) that are usable have the potential to improve patient care, which is why the National Institute of Standards and Technology has outlined formal procedures for evaluating the usability of EHR systems.
Space Image: Sunspots and solar flares
NASA is on course to make the highest leap in human spaceflight in nearly 4 decades when an unmanned Orion crew capsule blasts off from Cape Canaveral, Fla., on a high stakes, high altitude test flight in early 2014.
Space observations of Mercury transits yield precise solar radius
(PhysOrg.com) -- NASA's Solar Dynamics Observatory (SDO) captured this image of an M7.9 class flare on March 13, 2012 at 1:29 p.m. EDT. It is shown here in the 131 Angstrom wavelength, a wavelength particularly good for seeing solar flares and a wavelength that is typically colorized in teal. The flare peaked at 1:41 p.m. EDT. It was from the same active region, No. 1429, that produced flares and...
Speca -- An intriguing look into the beginning of a black hole jet
(PhysOrg.com) -- A group of scientists from Hawaii, Brazil and California has measured the diameter of the Sun with unprecedented accuracy by using a spacecraft to time the transits of the planet Mercury across the face of the Sun in 2003 and 2006.
Study of Patagonian Glacier's rise and fall adds to understanding of global climate change
Its catalog number is NGC 3801, but its name is SPECA a Spiral-host Episodic radio galaxy tracing Cluster Accretion. Thats certainly a mouthful of words for this unusual galaxy, but theres a lot more going on here than just its name. This is probably the most exotic galaxy with a black hole, ever seen. It has the potential to teach us new lessons about how galaxies and...
Through MoonMappers, the public is offered a chance to be part of NASA Lunar Science
(PhysOrg.com) -- Glaciers play a vital role in Earths climate system, and its critical to understand what contributes to their fluctuation.
Wolves eating less than 1% of German livestock, study finds
The MoonMappers citizen science project at CosmoQuest.org invites the public to become part of the Lunar Reconnaissance Orbiters science team. Through this project, the public is invited to explore high-resolution Lunar images and map out scientifically interesting features. People can get engaged at http://cosmoquest.org/moonmappers
Yahoo shareholder pushes for its board nominees
Despite the reappearance of wolves in Germany, local farmers should not worry about these creatures attacking and eating their livestock. Less than 1% of farm animals are on the wolves' menu, new research shows. Presented in the journal Mammalian Biology, the study highlights how wolves will not risk confrontation with guard dogs or hazardous objects in order to secure food.
Valuing nature, changing economics
(AP) -- One of Yahoo's major investors is urging shareholders to vote its four nominees on to the Internet company's board, launching a potentially nasty fight to transform the Internet company's board.
Daily Aspirin Linked to Reduced Cancer Risk
Putting a price on nature is the new green - the oceans are the latest - but will it work?
Green Blog: On Our Radar: Obama's Energy Blitz
Taking aspirin once a day may help prevent cancer, and perhaps even in some cases treat it, a growing body of research suggests.

Ultra-Deep Cosmic Photo Catches Over 200,000 Galaxies
The president plans stops in Nevada and New Mexico to emphasize diversification of the nation's energy sources.
Noise disrupts growth of plants
More than 200,000 galaxies take center stage in a staggering photo snapped by a European telescope, an image that scientists say is the deepest view of the sky ever recorded at this size in infrared light.
A Challenge to Einstein’ Theory Falls in Retest of Neutrinos’ Speed
By disrupting the behaviour of animals that disperse plant seeds man-made noise could be transforming our landscape, scientists say.
