ANN ARBOR, Mich.---A new mathematical model by researchers at the University of Michigan suggests that bluffing in prediction markets is a profitable strategy more often than previously thought.
The analysis calls into question the incentives such markets create for revealing information and making accurate predictions. The researchers also pose a tactic to discourage bluffing.
WASHINGTON, DC—While the 2008 summer Olympics in Beijing has elicited a rallying cry for human rights among high-profile activists and organizations outside China, ordinary Chinese citizens are mobilizing to fight for their rights inside the rapidly changing country, according to sociologist Ching Kwan Lee, writing in the summer issue of the American Sociological Association's Contexts magazine.

WASHINGTON -- Policymakers, universities, and employers should work together to speed the development of professionally oriented master's degree programs in the natural sciences, says a new report from the National Research Council. Graduates of these programs -- which build both scientific knowledge and practical workplace skills -- can make a strong contribution to the nation's competitiveness, said the committee that wrote the report.
LIVERMORE, Calif. - Researchers have devised a technology that can distinguish mine collapses from other seismic activity.
Washington -- The Senate today gave overwhelming, bipartisanapproval to legislation to avert cuts in Medicare physician paymentupdates--the best outcome possible given the difficult circumstancesfacing us, Jeffrey P. Harris, MD, FACP, president of the AmericanCollege of Physicians (ACP) said today. We implore President Bushto immediately sign this bill into law. The votes in both the Senateand House in favor of H.R. 6331 are more than enough to override apresidential veto, but we hope that it doesnt come to that.
However much the likes of Jamie Oliver or Gordon Ramsay might want to shake up our diets, culinary evolution dictates that our cultural cuisines remain little changed as generations move on, shows new research, published today, Thursday, 10 July, 2008, in the Institute of Physics (IOP)'s New Journal of Physics (NJP).
Naturopaths are strongly in favour of regulation of their industry, a University of Queensland researcher has found.
Naturopaths believed that regulation would lift the quality of practitioners, improve patient safety, promote research and allow for greater collaboration between complementary and conventional medicine, researcher Jon Wardle, a PhD student with the School of Population Health, said.
The economic and psychological term known as "sunk-cost fallacy" is a bias that leads someone to make a decision based solely on a previous financial investment. For example, a baseball fan might attend every game of the season only because he already purchased the tickets. But not everyone would force themselves to brave the pouring rain for a single game in one season simply because they previously paid for the seats.
As museums continue to digitize their art collections, it becomes increasingly easier for paintings to be forged. Two Penn State researchers are part of an international team working on a digital system to help detect original works from counterfeit ones.
James Z. Wang, associate professor of information sciences and technology, Jia Li, associate professor of statistics, and their colleagues published their work in the July issue of IEEE Signal Processing.
The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island. Since the connection to the island in the image centre helps to stabilise the ice shelf, it is likely the break-up of the bridge will put the remainder of the ice shelf at risk.
In the first in-depth study of its kind ever done in the Southeastern United States, researchers at the University of Georgia and Emory University have discovered a link between thunderstorms and asthma attacks in the metro Atlanta area that could have a "significant public health impact."
While a relationship between thunderstorms and increased hospital visits for asthma attacks has been known and studied worldwide for years, this is the first time a team of climatologists and epidemiologists has ever conducted a detailed study of the phenomenon in the American South.
RICHLAND, Wash. -- Many coaches inspire better performance by pressuring their teams. Now, proteomics researchers are using pressure to improve the performance of their analyses. In a simple solution to a time-consuming problem, the researchers have found that adding pressure early in their protocol squeezes four hours of waiting into a minute.
SALT LAKE CITY Certain songbirds can contract their vocal muscles 100 times faster than humans can blink an eye placing the birds with a handful of animals that have evolved superfast muscles, University of Utah researchers found.
"We discovered that the European starling (found throughout Eurasia and North-America) and the zebrafinch (found in Australia and Indonesia) control their songs with the fastest-contracting muscle type yet described," says Coen Elemans, who conducted the study as a postdoctoral researcher in biology at the University of Utah.
