Dear Reader ,

Integral challenges physics beyond Einstein
(PhysOrg.com) -- ESA's Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum 'graininess' of space must be at much smaller scales than previously predicted.
IBM scientists demonstrate computer memory breakthrough
(PhysOrg.com) -- For the first time, scientists at IBM Research have demonstrated that a relatively new memory technology, known as phase-change memory (PCM), can reliably store multiple data bits per cell over extended periods of time. This significant improvement advances the development of low-cost, faster and more durable memory applications for consumer devices, including mobile phones and cloud storage, as well as high-performance applications, such as enterprise data storage.
Inkjet printing could change the face of solar energy industry
Inkjet printers, a low-cost technology that in recent decades has revolutionized home and small office printing, may soon offer similar benefits for the future of solar energy.
World record: The strongest magnetic fields created
On June 22, 2011, the Helmholtz-Zentrum Dresden-Rossendorf set a new world record for magnetic fields with 91.4 teslas. To reach this record, Sergei Zherlitsyn and his colleagues at the High Magnetic Field Laboratory Dresden (HLD) developed a coil weighing about 200 kilograms in which electric current create the giant magnetic field – for a period of a few milliseconds. The coil survived the experiment unscathed.
Vertical cavity quantum switch could lead us away from electronics-based computing
(PhysOrg.com) -- Right now, many researchers around the world are working on ways to move away from electronics-dominated computing systems. There are a number of ideas about how this can be accomplished. "We are trying to demonstrate an all-optical switch that, at the first stage, could be used in ultrafast optical communication systems," Chaoyuan Jin tells PhysOrg.com. "It might also be useful for optical interconnection to replace present day electronic links which transfer tremendous data between computer chips, or perhaps useful for optical computing on-chip."
Northwestern research team turns theory of static electricity on its head
(PhysOrg.com) -- Bartosz Grzybowski, a physical chemist at Northwestern University, and his team of colleagues offer evidence in a paper published in Science, that shows that what scientists have believed to be true about the causes behind the creation of static electricity, is wrong. Instead of one object winding up with more or less electrons as a result of rubbing together, they claim, there is an actual transfer of slight amounts of actual material.
Finding showing human ancestor older than previously thought offers new insights into evolution
(PhysOrg.com) -- Modern humans never co-existed with Homo erectus -- a finding counter to previous hypotheses of human evolution—new excavations in Indonesia and dating analyses show. The research, reported in the journal PLoS One, offers new insights into the nature of human evolution, suggesting a different role for Homo erectus than had been previously thought.
An Israeli algorithm sheds light on the Bible
Software developed by an Israeli team is giving intriguing new hints about what researchers believe to be the multiple hands that wrote the Bible. The new software analyzes style and word choices to distinguish parts of a single text written by different authors, and when applied to the Bible its algorithm teased out distinct writerly voices in the holy book.
Spectacular discoveries in New Guinea
A frog with fangs, a blind snake and a round-headed dolphin are among more than 1,000 new species recently found on the incredible Melanesian island of New Guinea, environment group WWF said.
Clocking Neptune's spin
(PhysOrg.com) -- By tracking atmospheric features on Neptune, a UA planetary scientist has accurately determined the planet's rotation, a feat that had not been previously achieved for any of the gas planets in our solar system except Jupiter.
The math of the Rubik's cube
Last August, 30 years after the Rubik’s cube first appeared, an international team of researchers proved that no matter how scrambled a cube got, it could be solved in no more than 20 moves. Although the researchers used some clever tricks to avoid evaluating all 43 quintillion of the cube’s possible starting positions, their proof still relied on the equivalent of 35 years’ worth of number crunching on a good modern computer.
Astronomers reveal a cosmic 'axis of evil'
(PhysOrg.com) -- Astronomers are puzzled by the announcement that the masses of the largest objects in the Universe appear to depend on which method is used to weigh them. The new work was presented at a specialist discussion meeting on 'Scaling Relations of Galaxy Clusters' organised by the Astrophysics Research Institute (ARI) at Liverpool John Moores University and supported by the Royal Astronomical Society.
At small scales, tug-of-war between electrons can lead to magnetism under surprising circumstances
(PhysOrg.com) -- At the smallest scales, magnetism may not work quite the way scientists expected, according to a recent paper in Physical Review Letters by Rafal Oszwaldowski and Igor Zutic of the University at Buffalo and Andre Petukhov of the South Dakota School of Mines and Technology.
Breaking Kasha's rule: Scientists find unique luminescence in tetrapod nanocrystals
Observation of a scientific rule being broken can sometimes lead to new knowledge and important applications. Such would seem to be the case when scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) created artificial molecules of semiconductor nanocrystals and watched them break a fundamental principle of photoluminescence known as "Kasha's rule."
Predicting random violence by mathematics
(PhysOrg.com) -- In a new study published in Science, researchers, led by physicist Neil Johnson from the University of Miami, show that attacks by groups such as the Taliban or Hezbollah may seem sporadic, they eventually begin to follow a mathematical pattern.
Metal particle generates new hope for H2 energy
(PhysOrg.com) -- Tiny metallic particles produced by University of Adelaide chemistry researchers are bringing new hope for the production of cheap, efficient and clean hydrogen energy.
Water can flow below -130 C
When water is cooled below zero degrees, it usually crystallizes directly into ice. Ove Andersson, a physicist at Umea University, has now managed to produce sluggishly flowing water at 130 degree below zero under high pressure – 10,000 times higher than normal pressure. It is possible that this sluggishly fluid and cold water exists on other heavenly bodies.
Royal College of Art student make a 3D printer that focuses the light of the sun
(PhysOrg.com) -- 3D printing has been around for a few years. If you hooked it up to a solar panel you could make it work with the sun, but still would not be as cool as doing it the way that Markus Kayser, a MA student at the Royal College of Art, has gone about it. He has create a 3D printing machine that is able to focus the rays of the sun through a glass ball with enough intensity that it can create a beam that is able to heat silica sand to its melting point. Silica sand is often used in manufacturing process of heat resistant products for its high melting point.
VoltAir shows off electricity powered plane concept at Paris Air Show that is slated for 2035
(PhysOrg.com) -- EADS is looking to release an entirely electricity powered plane by the year 2035. The plane, which has been dubbed the VoltAir, was shown off at the Paris Air Show, which took place last week. The Paris Air Show is one of the largest aviation shows in the world.
Global warming continues as greenhouse gas grows
(AP) -- A study released Tuesday says the world's climate is not only continuing to warm, it's adding greenhouse gases even faster than in the past.
