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…)
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…)
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…)
*Once large and wolf-like, coyotes ultimately became much smaller*
When the last ice age ended more than 10,000 years ago, many large species of mammals went extinct and others underwent changes in appearance. (more…)
It’s a powerful feeling, says anthropology graduate student Amanda Taylor, to stand where people stood thousands of years back and gaze out at the same water — the same sunsets — that they saw so long ago. (more…)
*Electrical signals can’t shut off, suggest UCLA researchers*
Most of us know what it means when it’s said that someone is depressed. But commonly, true clinical depression brings with it a number of other symptoms. These can include anxiety, poor attention and concentration, memory issues, and sleep disturbances.
Traditionally, depression researchers have sought to identify the individual brain areas responsible for causing these symptoms. But the combination of so many symptoms suggested to UCLA researchers that the multiple symptoms of depression may be linked to a malfunction involving brain networks — the connections that link different brain regions.

Washington, D.C. — Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. This phenomenon can only be found in certain materials at low temperatures, or can be induced under chemical and high external pressure conditions. (more…)
