Dear Reader ,
Here is your customized Phys.org Newsletter for week 24:
Simple theory may explain dark matter
Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole.
A video map of motions in the nearby universe
(Phys.org) �An international team of researchers, including University of Hawaii at Manoa astronomer Brent Tully, has mapped the motions of structures of the nearby universe in greater detail than ever before. The maps are presented as a video, which provides a dynamic three-dimensional representation of the universe through the use of rotation, panning, and zooming. The video was announced last week at the conference "Cosmic Flows: Observations and Simulations" in Marseille, France, that honored the career and 70th birthday of Tully.
Is a sleeping climate giant stirring in the Arctic?
(Phys.org) �Flying low and slow above the wild, pristine terrain of Alaska's North Slope in a specially instrumented NASA plane, research scientist Charles Miller of NASA's Jet Propulsion Laboratory, Pasadena, Calif., surveys the endless whiteness of tundra and frozen permafrost below. On the horizon, a long, dark line appears. The plane draws nearer, and the mysterious object reveals itself to be a massive herd of migrating caribou, stretching for miles. It's a sight Miller won't soon forget.
ZSW engineers build lithium-ion battery able to last for 27 years
(Phys.org) �Officials at Germany's Centre for Solar Energy and Hydrogen Research Baden-W�rttemberg, (ZSW) have issued a press release describing improvements they've made to lithium-ion batteries. They claim their improvements allow a single battery to be recharged up to 10,000 times while still retaining 85 percent of its charging capacity. Such a battery, if used in an electric car, they note, would allow its owner to recharge the battery every day for 27.4 years.
Concentrator solar cell with world's highest conversion efficiency of 44.4%
Sharp Corporation has achieved the world's highest solar cell conversion efficiency of 44.4%, using a concentrator triple-junction compound solar cell. These solar cells are used in a lens-based concentrator system that focuses sunlight on the cells to generate electricity.
New 31-km-long International Linear Collider ready for construction
Today the Linear Collider Collaboration published its Technical Design Report [PDF] for the International Linear Collider (ILC) - a proposed 31-kilometer electron-positron collider that will both complement and advance beyond the physics of the Large Hadron Collider.
Physicists show self-correcting quantum computers are theoretically possible
(Phys.org) �Using exotic components such as color codes, new phases of quantum matter, and extra dimensions, a team of physicists has shown that it's theoretically possible to construct a quantum computer that has the ability to correct itself whenever an error occurs.
Czechs present bicycle that can fly
Is it a bike? Is it a plane?
Automated 'coach' could help with social interactions (w/ Video)
Social phobias affect about 15 million adults in the United States, according to the National Institute of Mental Health, and surveys show that public speaking is high on the list of such phobias. For some people, these fears of social situations can be especially acute: For example, individuals with Asperger's syndrome often have difficulty making eye contact and reacting appropriately to social cues. But with appropriate training, such difficulties can often be overcome.
US court says human genes cannot be patented (Update 4)
The U.S. Supreme Court on Thursday unanimously threw out attempts to patent human genes, siding with advocates who say the multibillion-dollar biotechnology industry should not have exclusive control over genetic information found inside the human body.
Study explains decades of black hole observations
(Phys.org) �A new study by astronomers at NASA, Johns Hopkins University and Rochester Institute of Technology confirms long-held suspicions about how stellar-mass black holes produce their highest-energy light.
Man-made material shows surprisingly magnetic personality
(Phys.org) �Scientists from SLAC and Stanford have used finely tuned X-rays at the Stanford Synchrotron Radiation Lightsource (SSRL) to pin down the source of a mysterious magnetism that appears when two materials are sandwiched together.
There is more gas in the Galaxy than is dreamt of by astronomers
(Phys.org) �A survey from Herschel has revealed that the reservoir of molecular gas in the Milky Way is hugely underestimated - almost by one third - when it is traced with traditional methods. Monitoring the emission from ionised carbon, the new study identified molecular gas in the intermediate evolutionary stage between diffuse, atomic gas and the densest star-forming molecular clouds. The discovery not only indicates that there is more raw material for the formation of new stars in the Galaxy, but also that it extends farther than astronomers knew.
Closing the last Bell-test loophole for photons
(Phys.org) �An international team of researchers has reached a milestone in experimental confirmation of a key tenet of quantum mechanics, using ultra-sensitive photon detectors devised by PML scientists.
Discovery of new material state counterintuitive to laws of physics
(Phys.org) �When you squeeze something, it gets smaller. Unless you're at Argonne National Laboratory.
UltraRope announced to one-stop zoom up tall buildings
(Phys.org) �Elevator tech has hit a wall, or at least the wrong floor of the person's destination, with limitations that are unable to accommodate the world's tallest buildings. As buildings rise, logistical demands rise with them. The weight of steel cable does not make it easy for elevators to zoom straight to the top. Instead, they reach a limit and that is it. For example, people going up in a 828-metre-high tower, such as in Dubai, need to switch lifts once they have reached the top mark in one elevator, going over for another. Elevators today are also subject to severe strains such as building sway, potentially knocking them out of service under especially poor weather conditions.
Shark Wheel on a roll to reinvent skateboarder experience
(Phys.org) �A California-based company has a new kind of wheel for skateboards that delivers a novel shape and claims a special ride experience. This is the Shark Wheel, not circular, not square, but something more interesting. The wheels appear as square when in motion from a side view but the wheel geometry is more than that. The wheels feel circular to the rider, and viewing them along with more details may help to clear the mystique. The wheels are made of three strips each; these create a helical shape when they roll, and they form a sine wave pattern. When the wheels make contact with the ground, good things happen, say the team behind the wheels�the user gets speed, better grip, and a smoother ride.
Unfrozen mystery: Water reveals a new secret
Using revolutionary new techniques, a team led by Carnegie's Malcolm Guthrie has made a striking discovery about how ice behaves under pressure, changing ideas that date back almost 50 years. Their findings could alter our understanding of how the water molecule responds to conditions found deep within planets and could have implications for energy science. Their work is published in the Proceedings of the National Academy of Sciences.
Mysterious monument found beneath the Sea of Galilee
The shores of the Sea of Galilee, located in the North of Israel, are home to a number of significant archaeological sites. Now researchers from Tel Aviv University have found an ancient structure deep beneath the waves as well.
Cosmic giants shed new light on dark matter
(Phys.org) �Astronomers at the University of Birmingham (UK), Academica Sinica in Taiwan, and the Kavli Institute of Physics and Mathematics of the Universe in Japan, have found new evidence that the mysterious dark matter that pervades our universe behaves as predicted by the 'cold dark matter' theory known as 'CDM'.
