Dear Reader ,
Here is your customized PHYSorg.com Newsletter for week 18:
CERN scientists confine antihydrogen atoms for 1000 seconds
(PhysOrg.com) -- Seventeen minutes may not seem like much, but to physicists working on the Antihydrogen Laser Physics Apparatus (ALPHA) project at the CERN physics complex near Geneva, 1000 seconds is nearly four orders of magnitude better than has ever been achieved before in capturing and holding onto antimatter atoms. In a paper published in arXiv, a team of researchers studying the properties of antimatter, describe a process whereby they were able to confine antihydrogen atoms for just that long, paving the way for new experiments that could demonstrate properties of antimatter that until now, have been largely speculation.
Gravity Probe B confirms two Einstein theories
(PhysOrg.com) -- Stanford and NASA researchers have confirmed two predictions of Albert Einstein's general theory of relativity, concluding one of the space agency's longest-running projects.
New species of lizard created in lab that reproduces by cloning itself
(PhysOrg.com) -- A genetics research group working in a lab in Kansas, has succeeded in creating a new species of lizard by mating two distinct species of North American Whiptails, both native to New Mexico. The offspring, all females are not only fertile, but can reproduce by laying eggs that don't need to be fertilized, which means, they actually clone themselves.
A water ocean on Titan?
Oddities in the rotation of Saturn's largest moon Titan might add to growing evidence that it harbors an underground ocean, researchers suggest.
Report sees sharper sea rise from Arctic melt (Update)
(AP) -- The ice of Greenland and the rest of the Arctic is melting faster than expected and could help raise global sea levels by as much as 5 feet this century, dramatically higher than earlier projections, an authoritative international assessment says.
Proposed gamma-ray laser could emit 'nuclear light'
(PhysOrg.com) -- Building a nuclear gamma-ray laser has been a challenge for scientists for a long time, but a new proposal for such a device has overcome some of the most difficult problems. In the new study, Eugene Tkalya from the Institute of Nuclear Physics at Moscow State University has theoretically proven how the stimulated gamma emission of thorium nuclei can emit coherent visible light. Although the nuclear gamma-ray laser emits light based on stimulated emission, it operates a bit differently than a normal laser.
Intel redesigns transistors for faster computers
Intel Corp. said Wednesday that it has redesigned the electronic switches on its chips so that computers can keep getting cheaper and more powerful.
Solar power, with a side of hot running water
MIT researchers and their collaborators have come up with an unusual, highly efficient and possibly less expensive way of turning the sun’s heat into electricity.
Japanese company introduces irresistibly cute mind-controlled 'cat ears' (w/ video)
(PhysOrg.com) -- In a bit of science mixed with whimsy, a Japanese company has created a set of electromechanical cat ears that can be worn on the human head and manipulated with nothing but the mind. Called the necomimi (a combination of the Japanese words for cat and ear) and looking very much like the ears that come with a cat costume, the ears respond to thoughts or mood by means of a sensor on a second small band pressed against the forehead; they can stand straight up when the wearer is concentrating, or wriggle and turn slightly when amused, or lay flat when tired or bored, demonstrating what the company calls, an ability to reveal emotion.
I control therefore I am: chimps self-aware, says study
Chimpanzees are self-aware and can anticipate the impact of their actions on the environment around them, an ability once thought to be uniquely human, according to a study released Wednesday.
Revolutionary new paper computer shows flexible future for smartphones, tablets (w/ video)
(PhysOrg.com) -- The world's first interactive paper computer is set to revolutionize the world of interactive computing.
Mystery force may be due to mirrors
Portuguese physicists report that they have identified the unknown force whose influence on outward bound interplanetary space probes has puzzled scientists since 1998.
Robots learn to share, validating Hamilton's rule (w/ video)
Using simple robots to simulate genetic evolution over hundreds of generations, Swiss scientists provide quantitative proof of kin selection and shed light on one of the most enduring puzzles in biology: Why do most social animals, including humans, go out of their way to help each other? In next week's issue of the online, open access journal PLoS Biology, EPFL robotics professor Dario Floreano teams up with University of Lausanne biologist Laurent Keller to weigh in on the oft-debated question of the evolution of altruism genes.
The $25 educational PC
(PhysOrg.com) -- Have you ever played Elite? What about games in the Rollercoaster Tycoon series, Thrillville, Lost Winds, or Kinectimals? If so, then you have enjoyed the work of David Braben. Mr. Braben is a fairly well known video game designer, he also runs the UK development studio Frontier Developments, but soon he may be known as much for his hardware as he is for his software.
Mozilla resists request to remove Firefox tool
Mozilla, the non-profit developer of the Firefox Web browser, is holding off on complying with a government request to remove a software tool meant to circumvent federal efforts at curbing Internet piracy.
Single atom stores quantum information
(PhysOrg.com) -- A data memory can hardly be any smaller: researchers working with Gerhard Rempe at the Max Planck Institute of Quantum Optics in Garching have stored quantum information in a single atom. The researchers wrote the quantum state of single photons, i.e. particles of light, into a rubidium atom and read it out again after a certain storage time. This technique can be used in principle to design powerful quantum computers and to network them with each other across large distances.
Combining gas and diesel engines could yield best of both worlds
It may be hard to believe, but the beloved gasoline engine that powers more than 200 million cars across America every day didn't get its status because it's the most efficient engine. Diesel engines can be more than twice as efficient, but they spew soot and pollutants into the air.
Dawn probe reaches milestone approaching asteroid Vesta
(PhysOrg.com) -- NASA's Dawn spacecraft has reached its official approach phase to the asteroid Vesta and will begin using cameras for the first time to aid navigation for an expected July 16 orbital encounter. The large asteroid is known as a protoplanet – a celestial body that almost formed into a planet.
More than 20 percent of atheist scientists are spiritual
More than 20 percent of atheist scientists are spiritual, according to new research from Rice University. Though the general public marries spirituality and religion, the study found that spirituality is a separate idea – one that more closely aligns with scientific discovery – for "spiritual atheist" scientists.
Cosmic magnetic fields
The mention of cosmic-scale magnetic fields is still likely to met with an uncomfortable silence in some astronomical circles – and after a bit of foot-shuffling and throat-clearing, the discussion will be moved on to safer topics. But look, they’re out there. They probably do play a role in galaxy evolution, if not galaxy formation – and are certainly a feature of the interstellar medium and the intergalactic medium.
