COLUMBUS, Ohio—When renowned explorer Richard E. Byrd returned from the first-ever flight to the North Pole in 1926, he sparked a controversy that remains today: Did he actually reach the pole? Studying supercomputer simulations of atmospheric conditions on the day of the flight and double-checking Byrd's navigation techniques, a researcher at The Ohio State University has determined that Byrd indeed neared the Pole, but likely only flew within 80 miles of it before turning back to the Norwegian island of Spitsbergen. Gerald Newsom, professor emeritus of astronomy at ...

A study at the Virginia-Maryland Regional College of Veterinary Medicine has identified a chicken-killing virus as a promising treatment for prostate cancer in humans. Researchers have discovered that a genetically engineered Newcastle disease virus, which harms chickens but not humans, kills prostate cancer cells of all kinds, including hormone-resistant cancer cells. The work of Dr. Elankumaran Subbiah, an associate professor of virology in the Department of Biomedical Sciences and Pathobiology at Virginia Tech, along with Dr. Siba Samal, associate dean and chairman ...

The rapid growth of the solar power industry over the past decade may have exacerbated the global warming situation it was meant to soothe, simply because most of the energy used to manufacture the millions of solar panels came from burning fossil fuels. That irony, according to Stanford University researchers, is coming to an end. For the first time since the boom started, the electricity generated by all of the world's installed solar photovoltaic (PV) panels last year probably surpassed the amount of energy going into fabricating more modules, according to Michael ...

Tampa, FL (April 8, 2013) -- A new discovery about the malaria-related parasite Toxoplasma gondii -- which can threaten babies, AIDS patients, the elderly and others with weakened immune function -- may help solve the mystery of how this single-celled parasite establishes life-long infections in people. The study, led by a University of South Florida research team, places the blame squarely on a family of proteins, known as AP2 factors, which evolved from the regulators of flowering in plants. In findings published today in the Proceedings of the National Academy ...

PROVIDENCE, R.I. [Brown University] — A new study of how carbon is trapped and released by iron-rich volcanic magma offers clues about the early atmospheric evolution on Mars and other terrestrial bodies. The composition of a planet's atmosphere has roots deep beneath its surface. When mantle material melts to form magma, it traps subsurface carbon. As magma moves upward toward the surface and pressure decreases, that carbon is released as a gas. On Earth, carbon is trapped in magma as carbonate and degassed as carbon dioxide, a greenhouse gas that helps Earth's atmosphere ...

Exposure to tobacco smoke could negatively impact adolescent kidney function; this is according to a new study led by a team of researchers at the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins Children's Center.

The results are featured in the April 2013 issue of Pediatrics. "Tobacco use and exposure to secondhand tobacco smoke are major health problems for adolescents, ...

CHAPEL HILL, N.C. – A study from the University of North Carolina School of Medicine offers new insights into how the nervous system processes hot and cold temperatures. The research led by neuroscientist Mark J. Zylka, PhD, associate professor of cell biology and physiology, found an interaction between the neural circuits that detect hot and cold stimuli: cold perception is enhanced when nerve circuitry for heat is inactivated. "This discovery has implications for how we perceive hot and cold temperatures and for why people with certain forms of chronic pain, such as ...

An exploding star observed in 1604 by the German astronomer Johannes Kepler held a greater fraction of heavy elements than the sun, according to an analysis of X-ray observations from the Japan-led Suzaku satellite. The findings will help astronomers better understand the diversity of type Ia supernovae, an important class of stellar explosion used in probing the distant universe. "The composition of the star, its environment, and the mechanism of the explosion may vary considerably among type Ia supernovae," said Sangwook Park, an assistant professor of physics at the ...

However, the relationship between elder abuse and health services utilization still remains unclear," said Dr. XinQi Dong, a researcher and geriatrician at Rush University Medical Center and the study's lead author. ...

The shape of an individual's spinal column may predict his or her risk for nursing home admission or need of home assistance in old age, according to a new article published online in the Journals of Gerontology Series A: Biological Sciences and Medical Sciences. A team of researchers based in Japan discovered that the trunk angle of inclination — the angle between the true vertical and a straight line from the first thoracic vertebra to the first sacral vertebra (view image) — is associated with becoming dependent on help for activities of daily living (ADL). These activities ...

COLUMBIA, Mo. — Studies show 97 percent of American adults get less than 30 minutes of exercise a day, which is the minimum recommended amount based on federal guidelines. New research from the University of Missouri suggests certain genetic traits may predispose people to being more or less motivated to exercise and remain active. Frank Booth, a professor in the MU College of Veterinary Medicine, along with his post-doctoral fellow Michael Roberts, were able to selectively breed rats that exhibited traits of either extreme activity or extreme laziness. They say these rats ...

Monday, April 8, 2013, Cleveland: Patients who have open heart surgery for heart disease caused by radiation cancer treatment are nearly twice as likely to die in the years following their surgery compared to similar patients who did not undergo radiation treatment, according to new research from Cleveland Clinic published today in the American Heart Association journal Circulation. The team of researchers, led by Milind Desai, M.D., a cardiologist in the Sydell and Arnold Miller Family Heart & Vascular Institute at Cleveland Clinic, examined 173 patients who underwent ...

(Santa Barbara, Calif.) –– There's an epic battle taking place that's not on the national radar: intercellular competition. While it's not an Olympic event, new research from UC Santa Barbara demonstrates that this microscopic rivalry can be just as fierce as humans going for the gold. Christopher Hayes, UCSB associate professor of molecular, cellular and developmental biology, along with postdoctoral fellow Sanna Koskiniemi, graduate student James Lamoureux, and others, examined the role certain proteins, called rearrangement hotspots (Rhs), play in intercellular competition ...

WASHINGTON—Teenagers who increased the days on which they got just 20 minutes of exercise were able to cut down on their smoking habit. And teenage smokers were more likely to quit altogether if they participated in a smoking cessation/fitness program—and they ramped up the days on which they got at least 30 minutes of physical activity, according to a study published online April 9. "This study adds to evidence suggesting that exercise can help teenagers who are trying to quit smoking," says lead author Kimberly Horn, EdD, the Associate Dean for Research at the George ...
