Rosemont, Ill. – The American Academy of Orthopaedic Surgeons (AAOS) recently approved and released an evidence-based clinical practice guideline on the diagnosis of periprosthetic joint infections of the hip and knee. Clinical practice guidelines are one avenue the Academy uses to ensure that patients receive high quality care. A periprosthetic joint infection occurs when bacteria or other foreign organisms enter the wound during or at any point following joint replacement surgery, sometimes even years after surgery.

WASHINGTON, DC: Synthetic biology—defined as the design and construction of new biological parts, devices, and systems or re-design of existing natural biological systems for useful purposes—holds enormous potential to improve everything from energy production to medicine, with the global market projected to reach $4.5 billion by 2015. But what does the public know about this emerging field, and what are their hopes and concerns? A new poll of 1,000 U.S.

Athens, Ga. – What if there were a way to predict when a species was about to become extinct, in time to do something about it? Findings from a study by John M. Drake, associate professor in the University of Georgia Odum School of Ecology, and Blaine D. Griffen, assistant professor at the University of South Carolina, may eventually lead to such an outcome. Their study also has implications for understanding drastic, even catastrophic, changes in many other kinds of complex systems, from the human brain to entire ecosystems.

Research!America today called on Congress to take legislative action that will allow federal funding for human embryonic stem cell research to proceed, in light of U.S. District Judge Royce Lamberth's refusal yesterday to lift his recent injunction on federally funded research using embryonic stem cells.

St. Louis, MO, September, 8, 2010 – Despite a recession, some groups are happier with more costs and a larger government role in the restaurant industry, believing that a lack of federally mandated nutritional labeling for restaurant meals was why people are fat.

PASADENA, Calif.—We've all heard the predictions: e-commerce is going to be the death of traditional commerce; online shopping spells the end of the neighborhood brick-and-mortar store.

While it's true that online commerce has had an impact on all types of retail stores, it's not time to bring out the wrecking ball quite yet, says a team of researchers from the California Institute of Technology (Caltech).

MIAMI — September 8, 2010 -- Operational forecasting centers produce climate predictions that provide input for important decisions regarding water management, agriculture, and energy. "Assessment of Intraseasonal to Interannual Climate Prediction and Predictability", a new report from the National Research Council/National Academy of Sciences, examines current capabilities for making climate predictions -- such as seasonal hurricane or longer-term drought forecasts -- and identifies opportunities for improvement.

CHAMPAIGN, Ill. — The U.S. economy is experiencing anemic growth, yet businesses are sitting on a mountain of cash worth nearly $2 trillion, according to Federal Reserve estimates. But this trend is nothing new for firms, who have been steadily increasing their cash holdings over the past three decades, a University of Illinois business professor says.

Finance professor Heitor Almeida says the fact that businesses are stuffing corporate piggy banks with spare cash for the proverbial "rainy day" is unrelated to the belt-tightening brought about by the continuing financial crisis.

High testosterone levels in CEOs negotiating mergers and acquisitions are linked to a higher rate of dropped deals and an increase in hostile takeover attempts, according to a new study in the current issue of Management Science, a journal of the Institute for Operations Research and the Management Sciences (INFORMS®).

"Deal or No Deal: Hormones and the Mergers and Acquisitions Game" is by Maurice Levi, Kai Li, and Feng Zhang of the Sauder School of Business at the University of British Columbia. The study appears in the current issue of Management Science.

CHAMPAIGN, Ill. — A University of Illinois economist says consumers and investors concerned about the specter of deflation looming over an already bleak economic landscape should relax – for the time being, at least.

September 8, 2010 – Oakland, Calif. – A new analysis released today by the Pacific Institute recommends specific actions that can annually save a million acre-feet of water quickly and at a lower economic and ecological cost than developing new supplies. The assessment notes that new actions are immediately needed to reduce the growing tensions over the state's water resources and to address California's persistent water supply challenges.

Microbes could be threatening our cultural heritage by degrading historic cinematographic film and even preventing some valuable footage to be archived at all.

Mr Gavin Bingley who is presenting his work at the Society for General Microbiology's autumn meeting in Nottingham today describes how fungal growth on cinema film can not only lead to deterioration of the film but may also pose a risk to the archivist.

Seven years ago Northwestern University physicist Adilson E. Motter conjectured that the expansion of the universe at the time of the big bang was highly chaotic. Now he and a colleague have proven it using rigorous mathematical arguments.

The study, published by the journal Communications in Mathematical Physics, reports not only that chaos is absolute but also the mathematical tools that can be used to detect it. When applied to the most accepted model for the evolution of the universe, these tools demonstrate that the early universe was chaotic.
