Aluminum superatoms may split water Science News Share    
Tiny clusters of aluminum atoms may be able to quickly extract pure hydrogen from water, a new simulation suggests. The results offer an incredibly detailed view of how the molecules react and may help scientists develop new ways to produce pure hydrogen-based fuels, researchers report in an upcoming Physical Review Letters. More Geneva atom smasher seeks dark matter discoveries The Associated Press via Google Share
The world's largest atom smasher could generate its first scientific breakthrough later this year when operators hope to make discoveries into the elusive nature of dark matter, the director of the European Organization for Nuclear Research said. More
Superconductors could simulate the brain PhysicsWorld Share
Electronic components that exploit the phenomenon of superconductivity could allow us to study the collective behavior of large numbers of neurons operating over long timescales. That is the finding of scientists in the U.S., who have shown how networks of artificial neurons containing two Josephson junctions would outpace more traditional computer-simulated brains by many orders of magnitude. Studying such junction-based systems could improve our understanding of long-term learning and memory along with factors that may contribute to disorders like epilepsy. More RHIC nets strange antimatter PhysicsWorld Share
Physicists working in the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC) at the Brookhaven Laboratory in the U.S. have detected antimatter nuclei containing strange quarks for the first time. The antihypertriton -- consisting of an antiproton, an antineutron and an antilambda particle -- is the heaviest antinucleus yet produced and opens up a new realm of strange antinucluei. It could also shed light on a number of problems in astrophysics and cosmology, including the dominance of matter over antimatter in the universe. More Single photon solid-state memory for telecommunications PhysOrg Share
One of the issues associated with quantum information schemes revolves around the ability to develop quantum memories that allow for the retrieval of information on demand. Overcoming this issue is especially important for the advancement of long distance telecommunications. In order to use quantum means to send information over long distance, it is necessary to implement quantum repeaters so that data is not destroyed due to the absorption loss in optical fibers.

Galileo Galilei was right: Earth moves around the Sun, just as Nicolaus Copernicus said it did in 1543. But had Galileo followed the results of his observations to their logical conclusion, he should have backed another system -- the Tychonic view that Earth didn't move, and that everything else circled around it and the Sun, as developed by Danish astronomer Tycho Brahe in the sixteenth century.

Einstein's General Theory of Relativity manuscript on show The Jerusalem Post Share
The Israel Academy of Sciences, an institution so cloistered that no president or prime minister since David Ben-Gurion has visited the premises, is inviting the public the celebrate its 50th birthday with an unprecedented event: the first-ever public showing of Albert Einstein's 46-page original manuscripts of his General Theory of Relativity, handwritten in German. More Puffed-up planets are heated like toast NewScientist Share
A planet-sized version of an electric toaster could explain why some exoplanets get so large. A related phenomenon could be responsible for keeping in check the gusting winds that form the stripes of Jupiter. More New element copernicium wins a symbol at last NewScientist Share
More than a decade since it was first spotted, element 112, the newest element in the periodic table, has arrived at the finish line, winning its chemical symbol at last. More
A quantum leap for lighting The Economist Share
Quantum-dot lighting could surpass incandescents, compact fluorescents and even LEDs by providing greater power efficiency and softer, warmer light, in colors that can be precisely controlled. More Geophysicists push age of Earth's magnetic field back 250 million years ScienceNews Share
Evidence for the existence of Earth's magnetic field has been pushed back about 250 million years, new research suggests. The field may therefore be old enough to have shielded some of the planet's earliest life from the sun's most harmful cosmic radiation. More |
