Dear Reader ,

Maxwell's demon demonstration turns information into energy
(PhysOrg.com) -- Scientists in Japan are the first to have succeeded in converting information into free energy in an experiment that verifies the "Maxwell demon" thought experiment devised in 1867.
Antihydrogen trapped for first time (w/ Video)
(PhysOrg.com) -- In the movie Angels and Demons, scientists have solved one of the most perplexing scientific problems: the capture and storage of antimatter. In real life, trapping atomic antimatter has never been accomplished, until now.
Study suggests precognition may be possible
(PhysOrg.com) -- A Cornell University scientist has demonstrated that psi anomalies, more commonly known as precognition, premonitions or extra-sensory perception (ESP), really do exist at a statistically significant level. Psi anomalies are defined as "anomalous processes of information or energy transfer that are currently unexplained in terms of known physical or biological mechanisms."
Heisenberg Uncertainty Principle sets limits on Einstein's 'spooky action at a distance,' new research finds
Researchers have uncovered a fundamental link between the two defining properties of quantum physics. Stephanie Wehner of Singapore's Centre for Quantum Technologies and the National University of Singapore and Jonathan Oppenheim of the United Kingdom's University of Cambridge published their work today in the latest edition of the journal Science.
Light bending by a black hole may offer proof of extra dimensions
(PhysOrg.com) -- Researchers at the University of Pennsylvania report that a new test for measuring the ability of gravity to bend light seen from distant stars around large objects like black holes may offer proof of the existence of extra dimensions in the universe.
'Space-time cloak' to conceal events revealed in new study
(PhysOrg.com) -- The study, by researchers from Imperial College London, involves a new class of materials called metamaterials, which can be artificially engineered to distort light or sound waves. With conventional materials, light typically travels along a straight line, but with metamaterials, scientists can exploit a wealth of additional flexibility to create undetectable blind spots. By deflecting certain parts of the electromagnetic spectrum, an image can be altered or made to look like it has disappeared.
US scientists significantly more likely to publish fake research
US scientists are significantly more likely to publish fake research than scientists from elsewhere, finds a trawl of officially withdrawn (retracted) studies, published online in the Journal of Medical Ethics.
New property in warm superconductors discovered
(PhysOrg.com) -- Led by Simon Fraser University physicist Jeff Sonier, scientists at TRIUMF have discovered something that they think may severely hinder the creation of room-temperature (37 degrees Celsius) superconductors.
Racetrack memory
Imagine a computer equipped with shock-proof memory that's 100,000 times faster and consumes less power than current hard disks. EPFL Professor Mathias Klaui is working on a new kind of "racetrack" memory, a high-volume, ultra-rapid non-volatile read-write magnetic memory that may soon make such a creature possible.
Scientists ferret out a key pathway for aging
For decades, scientists have been searching for the fundamental biological secrets of how eating less extends lifespan.
Anti-mirror optical illusion could increase LED luminosity and laser power
(PhysOrg.com) -- By making multiple objects appear to look like only one using a "perfect lens," scientists have demonstrated a new optical illusion that could have practical applications in lighting systems. Normally, a mirror makes one object appear to look like two objects (the original object and its reflection). Since the new set-up does the opposite, the scientists have called the concept the "anti-mirror effect."
Researchers create iridescent glass that can reflect UV or infrared light
(PhysOrg.com) -- Using nanocrystals of cellulose, the main component of pulp and paper, chemistry researchers at the University of British Columbia have created glass films that have applications for energy conservation in building design because of their ability to reflect specific wavelengths of light, such as ultra violet, visible or infrared.
Laser-based camera can see around corners
(PhysOrg.com) -- Researchers from MIT have developed a camera that can capture images of a scene that is not in its direct line of sight. The camera is equipped with a femtosecond laser, which fires extremely short bursts of light that can reflect off one object (such as a door or mirror) and then a second object before reflecting back to the first object and being captured by the camera. Algorithms can then use this information to reconstruct the hidden scene.
New look at relativity: Electrons can't exceed the speed of light -- thanks to light itself, says biologist
When resolving why electrons can never beat the speed limit set by light, it might be best to forget about time. Thanks to insight from studying movement inside a biological cell, it seems that light itself -- not the relativity of time -- may be the traffic cop, according to a Cornell University biologist.
Sugar cube size supercomputers
(PhysOrg.com) -- IBM labs in Zurich may very well shrink a supercomputer processor down to the size of a sugar cube making it almost 50% more energy-efficient than the world's leading supercomputers.
Debunking and closing quantum entanglement 'loopholes'
(PhysOrg.com) -- An international team of physicists, including a scientist based at The University of Queensland, has recently closed an additional 'loophole' in a test explaining one of science's strangest phenomena -- quantum entanglement.
Vikings brought Amerindian to Iceland 1,000 years ago: study
The first Native American to arrive in Europe may have been a woman brought to Iceland by the Vikings more than 1,000 years ago, a study by Spanish and Icelandic researchers suggests.
Physicists demonstrate a four-fold quantum memory
Researchers at the California Institute of Technology (Caltech) have demonstrated quantum entanglement for a quantum state stored in four spatially distinct atomic memories.
Astronomers find first planet from another galaxy (w/ Video)
(PhysOrg.com) -- An exoplanet orbiting a star that entered our Milky Way from another galaxy has been detected by a European team of astronomers using the MPG/ESO 2.2-meter telescope at ESO's La Silla Observatory in Chile. The Jupiter-like planet is particularly unusual, as it is orbiting a star nearing the end of its life and could be about to be engulfed by it, giving tantalizing clues about the fate of our own planetary system in the distant future.
Low incomes make poor more conservative, study finds
You might think that in a time when more money is concentrated in fewer hands and incomes vary wildly from billions to subsistence, poor people might increase their support for government policies that offer some help.
