(Press-News.org) Alexandria, VA – An important question asked of recent graduates with geoscience majors is why they chose to major in the earth sciences. Recent analysis of over 400 responses from the National Geoscience Student Exit Survey from 71 geoscience departments identified several common answers among the respondents. Of those surveyed, many declared a geoscience major during their formative undergraduate years for a variety of reasons: enjoyment working in the outdoors, a lifelong interest in the subject and desire for career opportunities are among some of the most common.

Fairfax, Va., October 9, 2013—Standard and reduced high-dose volume radiation therapy for muscle-invasive bladder cancer provide comparable tumor control and decreased late toxicity when compared to surgery, according to a study published in the October 1, 2013 print edition of the International Journal of Radiation Oncology ● Biology ● Physics, the official scientific journal of the American Society for Radiation Oncology (ASTRO). The research is part of the United Kingdom's BC2001 clinical trial, one of the largest randomized trials conducted involving radiation ...

Researchers know that feeding some patients intravenously can save their lives – but also can cause liver damage. Now scientists at the University of Colorado and Children's Hospital Colorado have figured out the likely culprit, one of the ingredients in intravenous food, behind the liver problems.
The discovery, published Oct. 9 in Science Translational Medicine, could point the way to better treatments for patients who are medically vulnerable and, often, very young.
"We still have more to learn about the optimal mix of lipids for intravenous nutrition," said Ron ...

Terahertz (THz) radiation — radiation in the wavelength range of 30 to 300 microns — is gaining attention due to its applications in security screening, medical and industrial imaging, agricultural inspection, astronomical research, and other areas. Traditional methods of generating terahertz radiation, however, usually involve large and expensive instruments, some of which also require cryogenic cooling. A compact terahertz source — similar to the laser diode found in a DVD player —operating at room temperature with high power has been a dream device in the terahertz community ...

HOUSTON – (Oct. 9, 2013) – Carbyne will be the strongest of a new class of microscopic materials if and when anyone can make it in bulk.
If they do, they'll find carbyne nanorods or nanoropes have a host of remarkable and useful properties, as described in a new paper by Rice University theoretical physicist Boris Yakobson and his group. The paper appears this week in the American Chemical Society journal ACS Nano.
Carbyne is a chain of carbon atoms held together by either double or alternating single and triple atomic bonds. That makes it a true one-dimensional material, ...

New Rochelle, NY, October 9, 2013—A national survey has found that uterine fibroids have a disproportionate impact on African American women, causing more severe symptoms, interfering with their daily life, and causing them to miss work. These new findings are reported in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Women's Health website at http://www.liebertpub.com/jwh.
African American women have a 3-fold higher incidence of uterine fibroids and tend to have them at an ...

A new meta-analysis published today in the Journal of Alternative and Complementary Medicine (2013;19(10):1-12)1 found the Transcendental Meditation® technique (TM) has a large effect on reducing trait anxiety for people with high anxiety. Trait anxiety is a measure of how anxious a person usually is, as opposed to state anxiety, which refers to how anxious we are at the moment. A meta-analysis is an objective means to draw conclusions from all the research in a field.
This meta-analysis covered 16 randomized-controlled trials, the gold standard in medical research, and ...

More than 90 percent of the public supports organ donation, yet less than half the population registers as donors, surveys show.
What if registration was better promoted to those who had previously turned it down? And at the place almost everyone makes that decision, the DMV?
Research at 40 Department of Motor Vehicles facilities in Illinois shows such efforts can make a difference. An article about the work was published in the September/October issue of the journal Clinical Transplantation.
University of Illinois professor Brian Quick and his research colleagues implemented ...

Nyon, Switzerland (October 10, 2013) – According to a new report published today by the International Osteoporosis Foundation (IOF), women may expect to live longer but their quality of life will be seriously jeopardized if action to protect their bone health is not taken. Postmenopausal women are the most vulnerable to osteoporosis and fractures. Worldwide, an estimated 200 million women are affected by osteoporosis and around one in three women aged over 50 will suffer from a fracture due to the disease.
With an increasingly ageing population huge demands will be put ...

Vast areas on the Northern Hemisphere are covered by tundra. Here, dwarf shrubs, sedges, mosses etc. thrive on top of permafrost in areas where only the uppermost soil layer thaws during the short Arctic summer.
New studies show that the tundra may become a source of CO2 in the future. Researcher Magnus Lund from Aarhus University explains:
"The soil below the tundra contains very large quantities of carbon – more than twice as much as is present in the planet's entire atmosphere. Therefore, we would like to know if the carbon will stay put – or if it will be released ...

To most people, restoration of Florida's Everglades means recovering and protecting the wetlands of south Florida, including Everglades National Park. But what many don't realize is how intimately the fortunes of the southern Everglades are tied to central Florida's Lake Okeechobee and lands even further north.
"The Everglades at the southern tip of Florida—the remains of what was once a vast ecosystem—is interconnected with a large hydrologic system that really begins in Orlando with the northern Everglades," says Patrick Bohlen, a professor of biology at University ...
