LOS ANGELES — August 10, 2011 — Do you run when you should stay? Are you afraid of all the wrong things? An enzyme deficiency might be to blame, reveals new research in mice by scientists at the University of Southern California.
In a paper appearing in the October 2011 issue of the International Journal of Neuropharmacology, USC researchers show that mice lacking a certain enzyme due to genetic mutation are unable to properly assess threat. The mice exhibited defensive behaviors (such as biting or tail rattling) in the presence of neutral stimuli, such as plastic bottles. ...

WASHINGTON, DC—Orthopaedic surgeons from Children's National Medical Center are part of a team of researchers that has identified the genetic mutation causing Proteus syndrome, a rare disorder in which tissue and bone grow massively out of proportion. The discovery appears in the July 27, 2011, online edition of the New England Journal of Medicine. The study, led by researchers at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), may have larger implications in both the identification and treatment of Proteus syndrome, ...

Atlanta's Hartsfield-Jackson International Airport (ATL), one of the world's busiest international airports is also the most fiscally efficient, says an aviation think-tank based at the University of British Columbia's Sauder School of Business.
ATL generated 60 per cent of its total revenue from non-aviation activities, compared to the lowest-ranked North American airport Chicago's O'Hare International Airport (ORD), which derived only 34 per cent of its income from alternative sources.
The Air Transport Research Society (ATRS), headquartered at Sauder, has released ...

Algae-based fuel is one of many options among the array of possible future energy sources. New University of Virginia research shows that while algae-based transportation fuels produce high energy output with minimal land use, their production could come with significant environmental burdens.
For farmers looking to maximize profits, algae would produce considerably more transportation energy than canola and switch grass for every hectare planted, and can also be grown on poor-quality marginal land that cannot be easily used to grow food crops such as corn, according ...

CHICAGO --- Being physically active is one of best ways people with arthritis can improve their health, but a new study from Northwestern University Feinberg School of Medicine shows that more than half of women and 40 percent of men with arthritis are virtually couch potatoes.
This is the first study to use a device to objectively measure the physical activity of people with arthritis and determine if they meet federal guidelines. Past research relied on self-reported accounts of exercise and activity.
The study was published in Arthritis & Rheumatism, August 2011.

This release is available in French.
Dr. John Rioux, researcher at the Montreal Heart Institute, Associate Professor of Medicine at the Université de Montréal and original co-founder of the International Multiple Sclerosis Genetics Consortium is one of the scientists who have identified 29 new genetic variants linked to multiple sclerosis, providing key insights into the biology of a very debilitating neurological disease. Many of the genes implicated in the study are relevant to the immune system, shedding light onto the immunological pathways that underlie the development ...

A UCSF-led pilot study in San Francisco has found the highest levels ever reported among pregnant women worldwide of banned chemicals used in flame retardants, a likely result, they believe, of California's strict flammability regulations.
Polybrominated diphenyl ethers (PBDEs) were added to consumer products, such as electronics and foam in furniture beginning in the 1970s. The chemicals slow ignition and the rate at which a fire grows, according to the US Environmental Protection Agency (EPA).
Tests indicate that these chemicals may cause liver, thyroid, and neurodevelopmental ...

Biologists and psychologists know that light affects mood, but a new University of Virginia study indicates that light may also play a role in modulating fear and anxiety.
Psychologist Brian Wiltgen and biologists Ignacio Provencio and Daniel Warthen of U.Va.'s College of Arts & Sciences worked together to combine studies of fear with research on how light affects physiology and behavior.
Using mice as models, they learned that intense light enhances fear or anxiety in mice, which are nocturnal, in much the same way that darkness can intensify fear or anxiety in diurnal ...

URBANA – Dieting postmenopausal women who want to avoid losing muscle as they lose fat should pay attention to a new University of Illinois study. Adding protein throughout the day not only holds hunger pangs at bay so that dieters lose more weight, it keeps body composition—the amount of fat relative to muscle—in better proportion.
"A higher-protein weight-loss diet is more protective of muscle," said Ellen Evans, a former U of I associate professor of kinesiology and community health and member of the university's Division of Nutritional Sciences.
Scientists in Evans's ...

DALLAS – Aug. 10, 2011 – People who frequently use tanning beds may be spurred by an addictive neurological reward-and-reinforcement trigger, researchers at UT Southwestern Medical Center have found in a pilot study.
This could explain why some people continue to use tanning beds despite the increased risk of developing melanoma, the most lethal form of skin cancer. The brain activity and corresponding blood flow tracked by UT Southwestern scientists involved in the study is similar to that seen in people addicted to drugs and alcohol.
"Using tanning beds has rewarding ...
