EARTH: Antarctic meteorite hunters

2012-12-18
(Press-News.org) Alexandria, VA – For more than 35 years, scientists from the Antarctic Search for Meteorites (ANSMET) program have been scouring glacial landscapes in search of meteorites. Since 1976, teams of physicists, meteorite specialists, and mountaineers have recovered thousands of untouched specimens from meteoroids, the moon and even Mars. Despite subzero temperatures and razor-sharp winds, scientists are lining up for the chance to experience the ultimate hunt for alien objects in the alien environment.

ANSMET teams either conduct systematic searches of a region or work as a scout teams making preliminary investigations of new sites that might be worth further exploration. Once discovered, the meteorites are carefully cataloged in the field and sent to the Smithsonian's National Museum of Natural History in Washington, D.C., where they are distributed to scientists for further research. What secrets will new specimens – locked away in the ice and yet to be discovered – hold about our solar system and the universe? Read the story online and find out at http://bit.ly/UtXc9R.

Plant sniffs out danger to prepare defenses against pesky insect

Plant sniffs out danger to prepare defenses against pesky insect
2012-12-18
UNIVERSITY PARK, Pa. -- A plant may start to prime its defenses as soon as it gets a whiff of a male fly searching for a mate, according to Penn State entomologists. Once tall goldenrod plants smell a sex attractant emitted by true fruit fly males, they appear to prepare chemical defenses that make them less appealing to female flies that could damage the plants by depositing eggs on them, the researchers said. "It's become increasingly clear in recent years that plants are responsive to odors," said Mark Mescher, assistant professor of entomology. "But previous examples ...

Can instilling racial pride in black teens lead to better educational outcomes?

2012-12-18
PITTSBURGH—African American adolescents tend to have more success in school if their parents instill in them a sense of racial pride, reducing their vulnerability to the effects of racial discrimination from teachers and peers. This is the conclusion of a University of Pittsburgh study published this fall in the journal Child Development. Titled "Parental Racial Socialization as a Moderator of the Effects of Racial Discrimination on Educational Success Among African American Adolescents," the research article shows that when African American parents use racial socialization—talking ...

Farm soil determines environmental fate of phosphorous

Farm soil determines environmental fate of phosphorous
2012-12-18
PROVIDENCE, R.I. [Brown University] — Just 20 years ago, the soils of the Amazon basin were thought unsuitable for large-scale agriculture, but then industrial agriculture — and the ability to fertilize on a massive scale — came to the Amazon. What were once the poorest soils in the world now produce crops at a rate that rivals that of global breadbaskets. Soils no longer seem to be the driver — or the limiter — of agricultural productivity. But a new Brown University-led study of three soybean growing regions, including Brazil, finds that soils have taken on a new role: ...

Should physicians prescribe cognitive enhancers to healthy individuals?

2012-12-18
Physicians should not prescribe cognitive enhancers to healthy individuals, states a report being published today in the Canadian Medical Association Journal (CMAJ). Dr. Eric Racine and his research team at the IRCM, the study's authors, provide their recommendation based on the professional integrity of physicians, the drugs' uncertain benefits and harms, and limited health care resources. Prescription stimulants and other neuropharmaceuticals, generally prescribed to treat attention deficit disorder (ADD), are often used by healthy people to enhance concentration, memory, ...

UI-led team confirms 'gusty winds' in space turbulence

UI-led team confirms gusty winds in space turbulence
2012-12-18
Imagine riding in an airplane as the plane is jolted back and forth by gusts of wind that you can't prove exist but are there nonetheless. Similar turbulence exists in space, and a research team led by the University of Iowa reports to have directly measured it for the first time in the laboratory. "Turbulence is not restricted to environments here on Earth, but also arises pervasively throughout the solar system and beyond, driving chaotic motions in the ionized gas, or plasma, that fills the universe," says Gregory Howes, assistant professor of physics and astronomy ...

Berkeley Lab scientists developing quick way to id people exposed to ionizing radiation

2012-12-18
There's a reason emergency personnel train for the aftermath of a dirty bomb or an explosion at a nuclear power plant. They'll be faced with a deluge of urgent tasks, such as identifying who's been irradiated, who has an injury-induced infection, and who's suffering from both. Unfortunately, there isn't a quick way to screen for people exposed to dangerous levels of radiation. There also isn't a quick way to distinguish between people suffering from radiation exposure versus an infection due to an injury or chemical exposure. The most common way to measure exposure ...

Chances seen rising for chikungunya outbreaks in NYC, Atlanta, Miami

2012-12-18
ITHACA, N.Y. – Global travel and climate warming could be creating the right conditions for outbreaks of a new virus in this country, according to a new Cornell University computer model. The model predicts that outbreaks of chikungunya, a painful virus transported by travelers and spread by the invasive Asian tiger mosquito, could occur in 2013 in New York City during August and September, in Atlanta from June through September, and year-round in Miami. The probability of a disease outbreak is correlated with temperature, as warmer weather allows the Asian tiger mosquito ...

Plumes across the Pacific deliver thousands of microbial species to West Coast

Plumes across the Pacific deliver thousands of microbial species to West Coast
2012-12-18
A surprising number of microorganisms – 99 percent more kinds than had been reported in findings published just four months ago – are leaping the biggest gap on the planet. Hitching rides in the upper troposphere, they're making their way from Asia across the Pacific Ocean and landing in North America. For the first time researchers have been able to gather enough biomass in the form of DNA to apply molecular methods to samples from two large dust plumes originating in Asia in the spring of 2011. The scientists detected more than 2,100 unique species compared to only ...

2 cups of milk a day ideal for children's health, new research shows

2012-12-18
TORONTO, Dec. 17, 2012—New research has answered one of the most common questions parents ask their doctors: How much milk should I be giving my children? The answer is two cups per day. "We started to research the question because professional recommendations around milk intake were unclear and doctors and parents were seeking answers," said Dr. Jonathon Maguire, a paediatrician at St. Michael's Hospital and the lead author of the study. Dr. Maguire and his team looked at how cow's milk affected body stores of iron and vitamin D – two of the most important nutrients ...
