Researchers Find Cancer News May Contribute to Confusion About Cancer

New research from North Carolina State University shows that most online news stories about cancer contain language that likely contributes to public uncertainty about the disease – a significant finding, given that at least one-third of Americans seek health information online.

“Previous studies show that more than 100 million Americans seek health information online, and that their findings affect their health decisions,” says Dr. Kami Kosenko, an assistant professor of communication at NC State and co-author of a paper describing the study. “But, while people facing uncertainty about cancer issues are likely to seek out additional information, we’ve found that there are features of the information they’re seeking that may actually exacerbate the uncertainty.” (more…)

Nobel Prize-winning economist and New York Times columnist Paul Krugman had some generally dismal news for the near capacity audience that came to Sprague Hall on Tuesday for his Jackson Institute-sponsored town hall meeting.

The gathering, aimed at undergraduates, was held in conjunction with Krugman’s visit to Yale to receive the Henry E. Howland Memorial Prize, one of the highest honors that the University bestows.

Krugman was introduced by President Richard C. Levin; the two were briefly colleagues in Yale’s Department of Economics in the 1970s. He kicked off the Q&A with background on the current economic situation. (more…)

Timely Depression Diagnosis Critical to Maintain Health of Elderly

*MU researchers find non-mood changes related to depression in elderly*

COLUMBIA, Mo. – Depression affects approximately 30 to 40 percent of nursing home residents, but it often goes unrecognized, according to American Geriatrics Society, which can lead to lower quality of life or even suicide. Now, researchers at the University of Missouri have found a series of indicators, other than changes in mood that are associated with the development of depression in nursing home residents.

“Prompt diagnosis and treatment of depression is essential to improve the quality of life for nursing home residents,” said Lorraine Phillips, assistant professor in the Sinclair School of Nursing. “Many elderly people develop certain clinical characteristics at the same time they develop depression. Understanding these changes is essential to quickly and accurately diagnosing depression in nursing home residents.” (more…)

Researchers Discover How Key Drug Kills Worms in Tropical Diseases

EAST LANSING, Mich. — In a major breakthrough that comes after decades of research and nearly half a billion treatments in humans, scientists have finally unlocked how a key anti-parasitic drug kills the worms brought on by the filarial diseases river blindness and elephantitis.

Understanding how the drug ivermectin works has the potential to lead to new treatments for the diseases, in which the body is infected with parasitic worms, said Charles Mackenzie, a professor of veterinary pathology in the College of Veterinary Medicine and researcher on the project. The diseases afflict about 140 million people worldwide, doing much of their damage in equatorial Africa.

“Ivermectin is one of the most important veterinary and human anti-parasitic agents ever,” Mackenzie said. “Knowing specifically how it interacts with the body’s own immune system and kills parasitic worms opens up whole new treatment avenues.”

The research appears in the current edition of the Proceedings of the National Academy of Sciences. (more…)

Revolutionary Computing: $100 Million DARPA Program to Develop Next Generation of High Performance Computers

Imagine that one of the world’s most powerful high performance computers could be packed into a single rack just 24 inches wide and powered by a fraction of the electricity consumed by comparable current machines. That would allow an unprecedented amount of computing power to be installed on aircraft, carried onto the battlefield for commanders – and made available to researchers everywhere.

Putting this computing power into a small and energy-efficient package, and making it reliable and easier to program, are among the goals of the new DARPA Ubiquitous High Performance Computing (UHPC) initiative. Georgia Tech researchers from three different units are supporting key components of this $100 million challenge, which will require development of revolutionary approaches not bound by existing computing paradigms.

Primordial Dry Ice Fuels Comet Jets

COLLEGE PARK, Md. – One of the biggest comet findings coming out of the amazing images and data taken by the University of Maryland-ledEPOXI mission as it zipped past comet Hartley 2 last week is that dry ice is the ‘jet’ fuel for this comet and perhaps many others.

Images from the flyby show spectacular jets of gas and particles bursting from many distinct spots on the surface of the comet. This is the first time images of a comet have been sharp enough to allow scientists to link jets of dust and gas with specific surface features. Analysis of the spectral signatures of the materials coming from the jets shows primarily CO₂ gas (carbon dioxide) and particles of dust and ice.

“Previously it was thought that water vapor from water ice was the propulsive force behind jets of material coming off of the body, or nucleus, of the comet,” said University of Maryland Astronomy Professor Jessica Sunshine, who is deputy principal investigator for the EPOXI mission. “We now have unambiguous evidence that solar heating of subsurface frozen carbon dioxide (dry ice), directly to a gas, a process known as sublimation, is powering the many jets of material coming from the comet. This is a finding that only could have been made by traveling to a comet, because ground based telescopes can’t detect CO₂ and current space telescopes aren’t tuned to look for this gas,” Sunshine said.
