12-Mile-High Martian Dust Devil Caught in Act

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.

*Music videos could play an influential role in young viewers’ development*

COLUMBIA, Mo. — Popular music videos have been criticized as having misogynistic messages and images. While more female music artists have gained visibility and created successful “brands” in recent years, critics argue that many of these artists are pushing the boundaries of acceptable norms with regard to race, gender and sexuality in popular culture.

*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…)

Many Young People Would Rather Surf the Web than Drive a Car

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…)

Soy and Menopause

*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…)

Organics Probably Formed Easily in Early Solar System

Complex organic compounds, including many important to life on Earth, were readily produced under conditions that likely prevailed in the primordial solar system. Scientists at the University of Chicago and NASA Ames Research Center came to this conclusion after linking computer simulations to laboratory experiments.

Fred Ciesla, assistant professor in geophysical sciences at UChicago, simulated the dynamics of the solar nebula, the cloud of gas and dust from which the sun and the planets formed. Although every dust particle within the nebula behaved differently, they all experienced the conditions needed for organics to form over a simulated million-year period. (more…)
