*Berkeley Lab Researchers Resolve Controversy Over Gallium Manganese Arsenide that Could Boost Spintronic Performance*

A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) in collaboration with scientist from University of Notre Dame have determined the origin of the charge-carriers responsible for the ferromagnetic properties that make gallium manganese arsenide such a hot commodity for spintronic devices. Such devices utilize electron spin rather than charge to read and write data, resulting in smaller, faster and much cheaper data storage and processing. (more…)

Device could save time and money for oil/gas industry

Mechanical engineering professor David Sinton and his research team have developed a process to analyze the behaviour of bitumen in reservoirs using a microfluidic chip, a tool commonly associated with the field of medical diagnostics. The process may reduce the cost and time of analyzing bitumen-gas interaction in heavy oil and bitumen reservoirs. (more…)

Ice Age Mariners From Europe Were Among America’s First People

Some of the earliest humans to inhabit America came from Europe according to a new book.

Across Atlantic Ice puts forward a compelling case for people from northern Spain travelling to America by boat, following the edge of a sea ice shelf that connected Europe and America during the last Ice Age, 14,000 to 25,000 years ago.

Across Atlantic Ice is the result of more than a decade’s research by leading archaeologists Professor Bruce Bradley of the University of Exeter and Dr Dennis Stanford of the Smithsonian Institution. Through archaeological evidence, they turn the long-held theory of the origins of New World populations on its head.

For more than 400 years, it has been claimed that people first entered America from Asia, via a land bridge that spanned the Bering Sea. We now know that some people did arrive via this route nearly 15,000 years ago, probably by both land and sea. (more…)

Video Games Depict Religion as Violent, Problematized, MU Study Shows

COLUMBIA, Mo. — In the past few years, the video game industry has grown from a niche market into a major part of mainstream media. This increase in popularity and use of technology has allowed video game developers to insert more detail and nuance into the storylines of their games. Many video games have begun incorporating religion as a key aspect to plot points and story lines. Greg Perreault, a doctoral student in the University of Missouri School of Journalism, found that the many newer-generation video games equate religion with violence in the game narratives. (more…)

Yale University researchers have discovered a key cellular mechanism that may help the brain control how much we eat, what we weigh, and how much energy we have.

The findings, published in the Feb. 28 issue of the Journal of Neuroscience, describe the regulation of a family of cells that project throughout the nervous system and originate in an area of the brain call the hypothalamus, which has been long known to control energy balances. (more…)
