*New computer modeling study, led by a Berkeley Lab scientist, could help revise understanding of permafrost’s role in global warming*

Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates.

The study also found that soil in high-latitude regions could shift from being a sink to a source of carbon dioxide by the end of the 21^st century as the soil warms in response to climate change. (more…)

Organic Photovoltaics: Solar Cells of the Future?

*Undergraduate researcher Safatul Islam is a member of a team in the College of Optical Sciences investigating organic photovoltaics, which can lead to improved electronics.*

As the summer dwindles down, many people eagerly welcome the decline of long sunny days. But for others, this period of shorter days signals the end of the sun’s longest duration of generously giving energy to this region of the world.

Safatul Islam, a University of Arizona sophomore studying chemical engineering and mathematics, is working with researchers to develop better ways to harness the sun’s power for human use. (more…)

Hips Take Walking in Stride; Ankles Put Best Foot Forward in Run

In a first-of-its-kind study comparing human walking and running motions – and whether the hips, knees or ankles are the most important power sources for these motions – researchers at North Carolina State University show that the hips generate more of the power when people walk, but the ankles generate more of the power when humans run. Knees provide approximately one-fifth or less of walking or running power.

The research could help inform the best ways of building assistive or prosthetic devices for humans, or constructing next-generation robotics, say NC State biomedical engineers Drs. Dominic Farris and Gregory Sawicki. The co-authors of a study on the mechanics of walking and running in the journal Interface, a Royal Society scientific journal, Sawicki and Farris are part of NC State’s Human PoWeR (Physiology of Wearable Robotics) Lab.

In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The surprising discovery, described in the Feb. 3 issue of Science Express, can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped by intersecting laser beams

JILA is jointly operated by the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder. (more…)

WASHINGTON — Scientists using NASA’s Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before.

Scientists think the antimatter particles were formed in a terrestrial gamma-ray flash (TGF), a brief burst produced inside thunderstorms and shown to be associated with lightning. It is estimated that about 500 such flashes occur daily worldwide, but most go undetected. (more…)

ARMONK, N.Y. – 14 Oct 2010: IBM (NYSE: IBM) today announced that it has acquired PSS Systems, a privately held company based in Mountain View, Calif. Financial terms of the deal were not disclosed.

PSS Systems’ software helps organizations analyze, automate and implement information governance policies across massive amounts of electronic business information and dispose of that information in an automated way. These capabilities are critical elements to remaining responsive to legal obligations while reducing data storage costs. (more…)

Time Machine Built in Europe, Russian Scientists Say

Russian physicists seriously believe that the Large Hadron Collider can be used for time travel. However, it will only happen when it starts working at full capacity and stops breaking down. If earlier time travel was considered science fiction, now it suddenly turned into the favorite pet project of theoretical physicists. Renowned physicist Kip Thorne of the California Institute of Technology once said in one of his lectures:
