UCLA Study Identifies Genes Linked to Post-Traumatic Stress Disorder
Why do some people experience post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? A new UCLA study may shed light on the answer. (more…)

A Martian dust devil roughly 12 miles high (20 kilometers) was captured whirling its way along the Amazonis Planitia region of Northern Mars on March 14. It was imaged by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. Despite its height, the plume is little more than three-quarters of a football field wide (70 yards, or 70 meters).
Dust devils occur on Earth as well as on Mars. They are spinning columns of air, made visible by the dust they pull off the ground. Unlike a tornado, a dust devil typically forms on a clear day when the ground is heated by the sun, warming the air just above the ground. As heated air near the surface rises quickly through a small pocket of cooler air above it, the air may begin to rotate, if conditions are just right. (more…)
An international research team is reporting the results of a research cruise they organized to study the amount, spread, and impacts of radiation released into the ocean from the tsunami-crippled reactors in Fukushima, Japan. The group of 17 researchers and technicians from eight institutions spent 15 days at sea in June 2011 studying ocean currents, and sampling water and marine organisms up to the edge of the exclusion zone around the reactors.

TORONTO, ON — Low oxygen levels in tumors can be used to predict cancer recurrence in men with intermediate-risk prostate cancer even before they receive radiation therapy. (more…)
*Vintage Timeline Designed by Charles and Ray Eames Continues to Inspire Interest in Math and Science*
ARMONK, N.Y. – 05 Apr 2012: To celebrate the history of math and its impact on the world, IBM has released Minds of Modern Mathematics, an iPad app that re-imagines a classic 50-foot infographic on the history of math created by husband-and-wife design team Charles and Ray Eames and displayed at the 1964 World’s Fair in New York City.
The app, which can be downloaded from the iPad App Store, is an interactive vintage-meets-digital experience for students, teachers, and tech fans that illustrates how mathematics has advanced art, science, music and architecture. It reinvents the massive timeline on the history of math from 1000 AD to 1960 that was part of Mathematica: A World of Numbers…and Beyond, IBM’s milestone World’s Fair exhibit. (more…)
ANN ARBOR, Mich.— More young adults today would rather hit the information highway than the open highway, say University of Michigan researchers.
In a new study in the journal Traffic Injury Prevention, Michael Sivak and Brandon Schoettle of the U-M Transportation Research Institute found that having a higher proportion of Internet users was associated with lower licensure rates among young persons.
And this is just not in the United States; it’s happening in other countries, too. (more…)
*Large-scale study finds soy may alleviate hot flashes in menopause*
In the most comprehensive study to date to examine the effects of soy on menopause, researchers have found that two daily servings of soy can reduce the frequency and severity of hot flashes by up to 26 percent, compared to a placebo.
The findings, published in Menopause: The Journal of the North American Menopause Association, reviewed 19 previous studies that examined more than 1,200 women. (more…)
