Texas Agrilife Research fire and brush control studies in the Rolling Plains on a working ranch-scale showed the benefits and limitations of managed fires for reducing mesquite encroachment while sustaining livestock production.

Sebastian Thrun talks about Google's amazing driverless car - and his very personal quest to save lives and reduce traffic accidents. Jawdropping video shows the DARPA Challenge-winning car motoring through city traffic with no one behind the wheel; dramatic test drive footage from TED2011 demonstrates how fast the thing can really go.

Imagine a cell phone battery that charges with every step you take or a spacesuit that uses astronauts' expended energy to run the suit's electronics. A team of college students conducting NASA research on this innovative use of nanotechnology took their research to new heights. The team, comprising Hannah Clevenson, Olivia Lenz and Tanya Miracle, flew an experiment related to their nanotechnology research on a NASA reduced-gravity flight.

Reducing the ability of certain bacteria to fix carbon dioxide can greatly increase their production of hydrogen gas that can be used as a biofuel. Researchers from the University of Washington, Seattle, report their findings in the current issue of online journal mBio.

Chemical changes in tree leaves subjected to warmer, drier conditions that could result from climate change may reduce the availability of soil nutrients, according to a Purdue University study.

Purdue University civil engineers are working with the Indiana Department of Transportation (INDOT) to perfect the use of recycled concrete for highway construction, a strategy that could reduce material costs by as much as 20 percent.

Researchers in America have shown that ozone -- a known pollutant at low levels in the earth's atmosphere, causing harmful effects on the respiratory system and sensitive plants -- can be reduced, on average, when electric vehicle charging is done at night time.

As manufacturers and other businesses step up efforts to cut waste, reduce energy use and improve the overall sustainability of their products and processes, the number of planet-friendly standards and regulations also is increasing at a rapid clip, creating a sometimes-confusing array of options for "going green." National Institute of Standards and Technology (NIST) researchers have prototyped a framework to help organizations of all types sort through the welter of choices and evaluate and implement sustainability standards most appropriate for their operations and interests.

A new study from the Karolinska Institute and Stockholm School of Economics shows that the brain has built-in mechanisms that trigger an automatic reaction to someone who refuses to share. In the study publishing next week in the online open access journal PLoS Biology, the subjects' sense of justice was challenged in a two-player monetary fairness game, and their brain activity was simultaneously measured using functional magnetic resonance imaging (fMRI). When bidders made unfair suggestions as to how to share the money, they were often punished by their partners even if it cost them. This reaction to unfairness could be reduced by targeting one specific brain region, the amygdala.

Lowering energy consumption associated with computer data storage (specifically, cloud computing) and saving millions of dollars are possible now, thanks to new memory technology, a field that researchers at the University of Pittsburgh have been exploring through a four-year, $1.9 million grant from the National Science Foundation (NSF) awarded in 2009 titled, "Large: Storage Class Memory Architecture for Energy Efficient Data Centers."

Neala Kendall, a graduate student from the University of Washington in Seattle, after studying cannery data on sockeye salmon harvested from Bristol Bay in Alaska, has discovered that the length of the average sockeye caught there, has been dropping for the past half century.

Meditation produces powerful pain-relieving effects in the brain, according to new research published in the April 6 edition of the Journal of Neuroscience.

On April 26, 1986, history's greatest nuclear accident took place northwest of the Ukrainian city of Chernobyl. Despite the scale of the disaster, 25 years later, we still do not know its real effects. An international team of investigators has shown for the first time that the colour of birds' plumage may make them more vulnerable to radioactivity.
