The brightest gamma ray beam ever created- more than a thousand billion times more brilliant than the sun- has been produced in research led at the University of Strathclyde- and could open up new possibilities for medicine.

Physicists have discovered that ultra-short duration laser pulses can interact with ionised gas to give off beams that are so intense they can pass through 20 cm of lead and would take 1.5 m of concrete to be completely absorbed.

SALT LAKE CITY, Sept. 19, 2011 – University of Utah engineers who built wireless networks that see through walls now are aiming the technology at a new goal: noninvasively measuring the breathing of surgery patients, adults with sleep apnea and babies at risk of sudden infant death syndrome (SIDS).

Gamers have solved the structure of a retrovirus enzyme whose configuration had stumped scientists for more than a decade. The gamers achieved their discovery by playing Foldit, an online game that allows players to collaborate and compete in predicting the structure of protein molecules.

After scientists repeatedly failed to piece together the structure of a protein-cutting enzyme from an AIDS-like virus, they called in the Foldit players. The scientists challenged the gamers to produce an accurate model of the enzyme. They did it in only three weeks.

Researchers from the University of Toronto, the King Abdullah University of Science & Technology and Pennsylvania State University have created the most efficient solar cell ever made based on collodial-quantum-dots (CQD), they report in the latest issue of Nature Materials.

EAST LANSING, Mich. — A research team at Michigan State University has developed a laser that could detect roadside bombs – the deadliest enemy weapon encountered in Iraq and Afghanistan.

Berkeley, CA — The installed cost of solar photovoltaic (PV) power systems in the United States fell in 2010 and into the first half of 2011, according to the latest edition of an annual PV cost tracking report released by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).

ANN ARBOR, Mich.---A new "subconscious mode" for smartphones and other WiFi-enabled mobile devices could extend battery life by as much as 54 percent for users on the busiest networks.

University of Michigan computer science and engineering professor Kang Shin and doctoral student Xinyu Zhang will present their new power management approach Sept. 21 at the ACM International Conference on Mobile Computing and Networking in Las Vegas. The approach is still in the proof-of-concept stage and is not yet commercially available.

An avatar is really no more than a graphical representation, generally human, which is associated with a user for identification purposes. Avatars can be either photographs or art drawings, and certain technologies enable their use in three dimensions.

Until now, 3D avatars were mainly used as fun objects for diversion and entertainment purposes of the end user. However, the Media Unit at Tecnalia has developed a "Personalised 3D avatars" technology, the aim of which is to facilitate the building of low-cost 3D avatars.

If solar cells could generate higher voltages when sunlight falls on them, they'd produce more electrical power more efficiently. For over half a century scientists have known that ferroelectrics, materials whose atomic structure allows them to have an overall electrical polarization, can develop very high photovoltages under illumination. Until now, no one has figured out exactly how this photovoltaic process occurs.

Cambridge, Mass. - Today's wireless-sensor networks can do everything from supervising factory machinery to tracking environmental pollution to measuring the movement of buildings and bridges. Working together, distributed sensors can monitor activity along an oil pipeline or throughout a forest, keeping track of multiple variables at a time.

Several new studies of air and water near the site of the Deepwater Horizon oil spill conclude that cleanup workers may have escaped harm from one of the most worrisome groups of potentially toxic substances in the oil, according to an article in Chemical & Engineering News (CEN). But it cites concerns that another group of potentially harmful chemicals did escape from the water and could create a health hazard for cleanup workers.

Do I toast my bread rolls in the oven or over the toaster? Should I heat the water on the stove or in the electric kettle? Do I start the washing machine in the afternoon or after 10 at night? How do I lower CO2 emissions by the way I use energy? Answers to such and similar questions are provided by the online game "RED" – which is an acronym for "Renewable Energy Drama." Researchers from the Fraunhofer Institute for Digital Media Technology IDMT in Erfurt, Germany, have developed the Web application in the course of the "RESIDENS" project.

Research scientists at the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute HHI in Berlin are working with twelve partners in the MUSCADE project on technologies which will make it possible to watch 3D TV without glasses.

Why? 3D glasses make the viewer feel more like they are in the middle of the action.

Jerusalem, September 13, 2011 --A team of researchers at the Hebrew University of Jerusalem says it has found a way to block a group of fatal bacterial toxins that have to date resisted all attempts to arrest them through the use of conventional drugs.
