EAST LANSING, Mich. — The use of stun guns by police significantly increases the chances of citizen injury, yet also protects the officers more than other restraint methods, according to the most comprehensive research to date into the safety of stun guns in a law enforcement setting. (more…)
Wind pushes plastics deeper into oceans, driving trash estimates up
Decades of research into how much plastic litters the sea may have only skimmed the surface. A new study reveals that wind drives confetti-sized pieces of plastic debris deeper underwater than previously believed, more than doubling earlier estimates of the pollutant’s presence in oceans.
“In windy conditions the traditional approach to measuring plastic marine debris captures only a small fraction of plastic pieces,” said Tobias Kukulka, assistant professor of physical ocean science and engineering in the University of Delaware’s College of Earth, Ocean, and Environment. “Our study helps to better understand how much plastic there is and where, as well as the complexity of the ocean dynamics at work.” (more…)
SUNNYVALE, Calif. — Yahoo! Small Business today announced the launch of Yahoo!

Berkeley Lab scientists demonstrate the promise of synchrotron infrared spectroscopy of living cells for medical applications
Knowing how a living cell works means knowing how the chemistry inside the cell changes as the functions of the cell change. Protein phosphorylation, for example, controls everything from cell proliferation to differentiation to metabolism to signaling, and even programmed cell death (apoptosis), in cells from bacteria to humans. It’s a chemical process that has long been intensively studied, not least in hopes of treating or eliminating a wide range of diseases. But until now the close-up view – watching phosphorylation work at the molecular level as individual cells change over time – has been impossible without damaging the cells or interfering with the very processes that are being examined.
“To look into phosphorylation, researchers have labeled specific phosphorylated proteins with antibodies that carry fluorescent dyes,” says Hoi-Ying Holman of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). “That gives you a great image, but you have to know exactly what to label before you can even begin.” (more…)
MU researchers recommend legislative action to help local economy, state revenue
COLUMBIA, Mo. – Internet, or e-commerce, sales have increased over the past two decades, comprising nearly 17 percent of the total U.S. sales in 2009. However, many states, including Missouri, have no effective means of collecting taxes on those sales. Researchers at the University of Missouri Truman School of Public Affairs found that the state lost approximately $468 million annually in sales tax revenue during the past decade.
Federal law and U.S. Supreme Court rulings only allow states to levy sales taxes on a business with a physical presence in the state. For example, Amazon.com does not charge sales tax in Missouri because it is physically located in California. However, Wal-Mart charges sales tax, since it has stores in Missouri. In the study, researchers analyzed historical data on e-commerce activity and estimated that the state will miss out on $1.4 billion in potential revenue from 2011 to 2014. (more…)
COLUMBUS, Ohio – Just 20 minutes of playing a violent shooting video game made players more accurate when firing a realistic gun at a mannequin – and more likely to aim for and hit the head, a new study found. (more…)
Using “random lasers” as a source of illumination in medical imaging equipment could improve both processing time and the clarity of the final images, according to new research by Yale University scientists.
Imaging systems currently rely on a variety of light sources — specialty light bulbs, light-emitting diodes (LEDs), and traditional lasers. But systems using traditional lasers, the brightest of these light sources, often yield undesirable visual byproducts that mar the final picture. One common byproduct, speckle, looks something like a snowfall pattern. (more…)
