Dear Reader ,

Universe's not-so-missing mass
(PhysOrg.com) -- A Monash student has made a breakthrough in the field of astrophysics, discovering what has until now been described as the Universe's 'missing mass'. Amelia Fraser-McKelvie, working within a team at the Monash School of Physics, conducted a targeted X-ray search for the matter and within just three months found it – or at least some of it.
Large Hadron Collider smashes another record
The world's biggest particle collider set a new record early Monday, a feat that should accelerate the quest to pinpoint the elusive particle known as the Higgs Boson, a senior physicist said.
The quantum computer is growing up: Repetitive error correction in a quantum processor
(PhysOrg.com) -- A team of physicists at the University of Innsbruck, led by Philipp Schindler and Rainer Blatt, has been the first to demonstrate a crucial element for a future functioning quantum computer: repetitive error correction. This allows scientists to correct errors occurring in a quantum computer efficiently. The researchers have published their findings in the scientific journal Science.
Parts of moon interior contains as much water as Earth's upper mantle
Parts of the moon's interior contains as much water as the upper mantle of the Earth - 100 times more of the precious liquid than measured before – research from Case Western Reserve University, Carnegie Institution for Science, and Brown University shows.
UK and European space agencies give a go for Skylon spaceplane
After 30 years of development, the UK and European space agencies have given a go for the Skylon Spaceplane.
Electron is surprisingly round, say scientists following 10 year study
(PhysOrg.com) -- Scientists at Imperial College London have made the most accurate measurement yet of the shape of the humble electron, finding that it is almost a perfect sphere, in a study published in the journal Nature today.
Researchers track the secret lives of feral and free-roaming house cats
Researchers (and some cat-owners) wanted to know: What do feral and free-roaming house cats do when they're out of sight? A two-year study offers a first look at the daily lives of these feline paupers and princes, whose territories overlap on the urban, suburban, rural and agricultural edges of many towns.
Details of new type of electric car battery released
(PhysOrg.com) -- After being spun off from parent company A123 Systems last year; the new offspring, 24M has published a paper in Advanced Energy Materials, ending months of speculation about what it has been working on. It was no secret that the new project was to advance work on a new type of battery that A123 had been working on for a couple of years; namely a battery that could be used to replace the lithium-ion batteries currently used in electric cars. Now, with the paper’s release it's clear that the new battery, similar to a flow battery, uses a liquid material to hold the charge, rather than conventional dry fuel cells, and if successful could do away with a lot of the non-charge holding stuff that makes up nearly three quarters of the bulk of current electric car batteries.
Single molecule performs multiple logic operations simultaneously
(PhysOrg.com) -- While molecules have already been used to perform individual logic operations, scientists have now shown that a single molecule can perform 13 logic operations, some of them in parallel. The molecule, which consists of three chromophores, is operated by different wavelengths of light. The scientists predict that this system, with its unprecedented level of complexity, could serve as a building block of molecular computing, in which molecules rather than electrons are used for processing and manipulating information.
26 terabits per second: World record in ultra-rapid data transmission
German scientists of Karlsruhe Institute of Technology have succeeded in encoding data at a rate of 26 terabits per second on a single laser beam, transmitting them over a distance of 50 km, and decoding them successfully. This is the largest data volume ever transported on a laser beam. The process developed by KIT allows to transmit the contents of 700 DVDs in one second only.
Fossil of giant ancient sea predator discovered (w/ video)
Paleontologists have discovered that a group of remarkable ancient sea creatures existed for much longer and grew to much larger sizes than previously thought, thanks to extraordinarily well-preserved fossils discovered in Morocco.
DARPA wants your ideas for a 100-year starship
The idea for a 100-year starship has been tossed around recently, and now DARPA the Defense Advanced Research Projects Agency, has put out a Request for Information (RFI) looking for ideas about how a long-term human mission to boldly go out to the stars could possibly happen. It’s been estimated that such a mission would cost over $10 billion, and the idea has gotten $100,000 from NASA and $ 1 million from DARPA – which means that as of now it is just that, an idea.
Small bangs and white holes
Most gamma-ray bursts come in two flavors. Firstly, there are long duration bursts which form in dense star-forming regions and are associated with supernovae – which would understandably generate a sustained outburst of energy. The technical definition of a long duration gamma-ray burst is one that is more than two seconds in duration – but bursts lasting over a minute are not unusual.
$25,000, 350-mile-per-charge electric car could be reality by 2017, DOE says
In an event flanked with all the electric cars that have recently come to market, and a handful of those that are poised for sale later this year, U.S. Energy Secretary Steven Chu and L.A. Mayor Antonio Villaraigosa flipped the switch May 13 on the 500th electric-vehicle charging station installed by Coulomb Technologies as part of its ChargePoint America network.
Satellites discover lost Egyptian pyramids
(PhysOrg.com) -- In a new documentary soon to air on BBC, space archaeologist Sarah Parcak from the University of Alabama in Birmingham shares her recent discovery in the relatively new field of space archaeology. With the use of satellites and infra-red imaging, Parcak and her team have discovered 17 lost pyramids, over 1,000 tombs and 3,000 ancient settlements in Egypt.
Matter-matter entanglement at a distance
(PhysOrg.com) -- Scientists at the Max Planck Institute of Quantum Optics prepare quantum mechanical entanglement of two remote quantum systems.
Chameleon magnets: ability to switch magnets 'on' or 'off' could revolutionize computing
(PhysOrg.com) -- What causes a magnet to be a magnet, and how can we control a magnet's behavior? These are the questions that University at Buffalo researcher Igor Zutic, a theoretical physicist, has been exploring over many years.
Black holes spinning faster than ever before
(PhysOrg.com) -- Two UK astronomers have found that the giant black holes in the centre of galaxies are on average spinning faster than at any time in the history of the Universe. Dr Alejo Martinez-Sansigre of the University of Portsmouth and Prof. Steve Rawlings of the University of Oxford made the new discovery by using radio, optical and X-ray data. They publish their findings in the journal Monthly Notices of the Royal Astronomical Society.
Most complete 3-D map of local universe unveiled
(PhysOrg.com) -- Today, astronomers unveiled the most complete 3-D map of the local universe (out to a distance of 380 million light-years) ever created. Taking more than 10 years to complete, the 2MASS Redshift Survey (2MRS) also is notable for extending closer to the galactic plane than previous surveys -- a region that’s generally obscured by dust.
Physicists explain the long, useful lifetime of carbon-14
The long, slow decay of carbon-14 allows archaeologists to accurately date the relics of history back to 60,000 years.
