COLUMBUS, Ohio – A new approach to motion capture technology is offering fresh insights into tennis injuries – and orthopedic injuries in general.
Researchers studied three types of tennis serves, and identified one in particular, called a “kick” serve, which creates the highest potential for shoulder injury. (more…)
Critical genetic secrets of a bacterium that holds potential for removing toxic and radioactive waste from the environment have been revealed in a study by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). The researchers have provided the first ever map of the genes that determine how these bacteria interact with their surrounding environment.
“Knowing how bacteria respond to environmental changes is crucial to our understanding of how their physiology tracks with consequences that are both good, such as bioremediation, and bad, such as biofouling,” says Aindrila Mukhopadhyay, a chemist with Berkeley Lab’s Physical Biosciences Division, who led this research. “We have reported the first systematic mapping of the genes in a sulfate-reducing bacterium – Desulfovibrio vulgaris – that regulate the mechanisms by which the bacteria perceive and respond to environmental signals.” (more…)
*U of T professors show collectivism and bribery linked*
Why are some places more prone to bribery and corruption than others?
Part of the answer seems to be the level of collective feeling in a society, according to research by Pankaj Aggarwal, University of Toronto Scarborough (UTSC) professor of marketing in the Department of Management, and Nina Mazar, University of Toronto professor of marketing. (more…)
COLUMBIA, Mo. – According to the Centers for Disease Control and Prevention, 25 percent of Americans have inactive lifestyles (they take fewer than 5,000 steps a day) and 75 percent do not meet the weekly exercise recommendations (150 minutes of moderate activity each week and muscle-strengthening activity twice a week) to maintain good health. After reviewing recent literature, University of Missouri researchers contend that physical inactivity is the primary cause of chronic diseases such as diabetes, obesity and fatty liver disease and that even people who set aside time for exercise regularly but are otherwise sedentary, may not be active enough to combat these diseases. Inactivity, in addition to the availability of high-caloric food has led to an increased rate of metabolic dysfunction in Americans. (more…)
A study by researchers at the UCLA Stroke Center found that stroke and cardiovascular disease have exacted an enormous toll on Hollywood stars.
The findings were presented at the American Heart Association/American Stroke Association’s International Stroke Conference (ISC) in Los Angeles on Feb. 10.
“Since this is the first time the ISC is being held in Los Angeles, we thought it was an appropriate occasion to investigate the frequency and impact of stroke among leading Hollywood actors,” said Hannah Smith, a staff research associate at the UCLA Stroke Center. “By documenting the toll that stroke and myocardial infarction have exacted on stars like Kirk Douglas and Grace Kelly, we hope to illustrate the damage that cardiovascular disease can cause.” (more…)
Yale University researchers have found that a single molecule not only connects brain cells but also changes how we learn. The findings, reported in the December 9 issue of the journal Neuron, may help researchers discover ways to improve memory and could lead to new therapies to correct neurological disorders.
The junctions between brain cells over which nerve pulses pass — called synapses — are crucial for regulating learning and memory and how we think. Aberrations in the structure and function of synapses have been linked to mental retardation and autism, while synapses are lost in the aging brains of Alzheimer’s patients. (more…)

EAST LANSING, Mich. — Researchers have long argued that marriage generally reduces illegal and aggressive behaviors in men. It remained unclear, however, if that association was a function of matrimony itself or whether less “antisocial” men were simply more likely to get married.
The answer, according to a new study led by a Michigan State University behavior geneticist, appears to be both.
In the December issue of the Archives of General Psychiatry, S. Alexandra Burt and colleagues found that less antisocial men were more likely to get married. Once they were wed, however, the marriage itself appeared to further inhibit antisocial behavior.
“Our results indicate that the reduced rate of antisocial behavior in married men is more complicated than we previously thought,” said Burt, associate professor of psychology. “Marriage is generally good for men, at least in terms of reducing antisocial behavior, but the data also indicate that it’s not random who enters into the state of marriage.” (more…)

Researchers at the Georgia Institute of Technology and Bennett Aerospace are leveraging light detection and ranging (lidar) technology to develop a ground-based system that will automatically measure water vapor in the atmosphere. Known as”WaV-ProTM,” for Water Vapor Profiler, the system aims to provide more frequent data collection that could dramatically improve weather forecasting.
Initial work on the project began in mid-2009, when Bennett Aerospace, in collaboration with the Georgia Tech Research Institute (GTRI), won a Phase I Small Business Innovation Research grant from the National Oceanic and Atmospheric Administration (NOAA) to develop design requirements for the system. Recently, the researchers won a Phase II grant to build and test critical components needed for a final operating prototype of WaV-Pro. (more…)
