ALBUQUERQUE, N.M. — High-gain nuclear fusion could be achieved in a preheated cylindrical container immersed in strong magnetic fields, according to a series of computer simulations performed at Sandia National Laboratories.

The simulations show the release of output energy that was, remarkably, many times greater than the energy fed into the container's liner. The method appears to be 50 times more efficient than using X-rays — a previous favorite at Sandia — to drive implosions of targeted materials to create fusion conditions.

CAMBRIDGE, MD (March 20, 2012)—Since the explosion on the BP Deepwater Horizon drilling rig in the Gulf of Mexico on April 20, 2010, scientists have been working to understand the impact that this disaster has had on the environment. For months, crude oil gushed into the water at a rate of approximately 53,000 barrels per day before the well was capped on July 15, 2010. A new study confirms that oil from the Macondo well made it into the ocean's food chain through the tiniest of organisms, zooplankton.

University of Granada researchers have proven that eating two servings of salmon reared at a fish farm (enriched with omega-3 fatty acids and only slightly contaminated) a week during pregnancy is beneficial both for the mother and child.

WASHINGTON--Engineers from the NRL Spacecraft Engineering Department (SED) successfully demonstrate the robotic fluids transfer from a stationary platform to an Unmanned Surface Vehicle (USV) in wave heights greater than three feet. The Rapid Autonomous Fuel Transfer (RAFT) project exhibits the ability to track the motion of a Sea Fox naval vessel, safely emplace a magnetic refueling fitting to an on-board refueling receptacle and successfully complete fluids transfer.

Politics aside, most energy experts agree that cheap, clean, renewable wind energy holds great potential to help the world satisfy energy needs while reducing harmful greenhouse gases. Wind farms placed offshore could play a large role in meeting such challenges, and yet no offshore wind farms exist today in the United States.

For 27 years, the Concorde provided its passengers with a rare luxury: time saved. For a pricey fare, the sleek supersonic jet ferried its ticketholders from New York to Paris in a mere three-and-a-half hours — just enough time for a nap and an aperitif. Over the years, expensive tickets, high fuel costs, limited seating and noise disruption from the jet's sonic boom slowed interest and ticket sales. On Nov. 26, 2003, the Concorde — and commercial supersonic travel — retired from service.

A Harvard archaeologist has dramatically simplified the process of finding early human settlements by using computers to scour satellite images for the tell-tale clues of human habitation, and in the process uncovered thousands of new sites that might reveal clues to the earliest complex human societies.

Nearly two-thirds of the oil we use comes from wells drilled using polycrystalline diamond compact (PDC) bits, originally developed nearly 30 years ago to lower the cost of geothermal drilling. Sandia and the U.S. Navy recently brought the technology fullcircle, showing how geothermal drillers might use the original PDC technology, incorporating decades of subsequent improvements by the oil and gas industry.

EUGENE, Ore. -- Technology alone won't help the world turn away from fossil fuel-based energy sources, says University of Oregon sociologist Richard York. In a newly published paper, York argues for a shift in political and economic policies to embrace the concept that continued growth in energy consumption is not sustainable.

DETROIT – Styling practices can lead to serious hair and scalp diseases for some African Americans, says Henry Ford Hospital dermatologist Diane Jackson-Richards, M.D.

"Hair is an extremely important aspect of an African-American woman's appearance," saysDr. Jackson-Richards, director of Henry Ford's Multicultural Dermatology Clinic. "Yet, many women who have a hair or scalp disease do not feel their physician takes them seriously. Physicians should become more familiar with the culturally accepted treatments for these diseases."

Researchers from North Carolina State University have found that including ads in mobile applications (apps) poses privacy and security risks. In a recent study of 100,000 apps in the official Google Play market, researchers noticed that more than half contained so-called ad libraries. And 297 of the apps included aggressive ad libraries that were enabled to download and run code from remote servers – which raises significant privacy and security concerns.

EAST LANSING, Mich. — Having a triple-threat combination of protective software on your computer greatly reduces your chances of identity theft, according to a study led by a Michigan State University criminologist.

In a survey of more than 600 people, the researchers found that computer users who were running antivirus, anti-adware and anti-spyware software were 50 percent less likely to have their credit card information stolen.

The study appears in the research journal Deviant Behavior.

New York, NY—March 18, 2012—As nanotechnology becomes ever more ubiquitous, researchers are using it to make medical diagnostics smaller, faster, and cheaper, in order to better diagnose diseases, learn more about inherited traits, and more. But as sensors get smaller, measuring them becomes more difficult—there is always a tradeoff between how long any measurement takes to make and how precise it is. And when a signal is very weak, the tradeoff is especially big.

DURHAM, N.C. -- Duke University engineers believe that continued advances in creating ever-more exotic and sophisticated man-made materials will greatly improve their ability to control light at will.

Eighty-eight percent of Americans now own a cell phone, forming a massive network that offers scientists a wealth of information and an infinite number of new applications. With the help of these phone users — and their devices' cameras, audio recorders, and other features — researchers envision endless possibilities for gathering huge amounts of data, from services that collect user data to monitor noise pollution and air quality to applications that build maps from people's cell phone snapshots.
