Closely contested major sporting events are followed by a significant increase in traffic fatalities for fans of the winning team, according to new research from North Carolina State University. It turns out there may be more on the line than many sports fans bargained for.

Getting someone's attention can be easy with a loud noise or a shout, but what if the situation calls for a little more tact? How can a robot use subtle cues to attract a human's notice and tell when it has captured it? In a preliminary study, researchers at the Georgia Institute of Technology have found that they can program a robot to understand when it gains a human's attention and when it falls short. The research is being presented today at the Human-Robot Interaction conference in Lausanne, Switzerland.

The researcher in question is Nadia Skorupa Parachin and the secret of her technique is enzymes that she extracted from garden soil. If ethanol can be successfully made from xylose then ethanol production could increase by over 20 per cent – to the benefit of cheaper environmentally friendly fuel.

Ethanol is manufactured by fermenting sugars from plant material. At present, xylose is not used, despite being the second most common type of sugar found in nature. Succeeding with xylose requires good, quick enzymes that can get the yeast to also ferment the less appetising xylose.

The percentage of personal bankruptcies linked to medical bills or illness changed little, and the absolute number actually increased in Massachusetts after the implementation of its landmark 2006 law requiring people to buy health insurance, a Harvard study says.

Circulating tumor cells, which play a crucial role in cancer metastasis, have been known to science for more than 100 years, and researchers have long endeavored to track and capture them. Now, a UCLA research team has developed an innovative device based on Velcro-like nanoscale technology to efficiently identify and "grab" these circulating tumor cells, or CTCs, in the blood.

CHAMPAIGN, Ill. — Cardiologists may soon be able to place sensitive electronics inside their patients' hearts with minimal invasiveness, enabling more sophisticated and efficient diagnosis and treatment of arrhythmias.

A team of materials scientists, mechanical and electrical engineers, and physicians has successfully integrated stretchable electronics technology with standard endocardial balloon catheters. Led by John A. Rogers, the Lee J. Flory-Founder Chair in Engineering at Illinois, the team published its work in the March 6 online edition of Nature Materials.

Troy, N.Y. – Steel walls are no match for Tristan Lawry. The doctoral student at Rensselaer Polytechnic Institute has developed and demonstrated an innovative new system that uses ultrasound to simultaneously transmit large quantities of data and power wirelessly through thick metal walls, like the hulls of ships and submarines.

Producers and feed companies add fat to swine diets to increase energy, but recent research from the University of Illinois suggests that measurements currently used for fat digestibility need to be updated.

"It's critical that we gain a better understanding of the energy value of fat," said Hans H. Stein, U of I professor in the Department of Animal Sciences. "If we don't know the true energy value of fat, we can't determine if it's economical to add to the diet."

PHILADELPHIA – It has been thought that the quality of the physician-patient relationship is integral to positive outcomes but until now, data to confirm such beliefs has been hard to find. Through a landmark study, a research team from Jefferson Medical College (JMC) of Thomas Jefferson University has been able to quantify a relationship between physicians' empathy and their patients' positive clinical outcomes, suggesting that a physician's empathy is an important factor associated with clinical competence. The study is available in the March 2011 issue of Academic Medicine.

KINGSTON, R.I. – March 7, 2011 – For those of us living the frenetic modern lifestyle, sitting in one place for a long period might seem like a vacation. But for those who are retired, it can lead to health complications.

Patricia Burbank, professor of nursing at the University of Rhode Island, realized that there is a need to get older adults moving.

The actual idea was inspired by Burbank's own aunt, a 97-year-old woman living on her own.

COLUMBIA, Mo. – America's 75 million aging adults soon will face decisions about where and how to live as they age. Current options for long-term care, including nursing homes and assisted-living facilities, are costly and require seniors to move from place to place. University of Missouri researchers have found that a new strategy for long-term care called Aging in Place is less expensive and provides better health outcomes.

TORONTO, ON., March 7, 2011—Screening every woman who comes to a health care centre does increase the number who acknowledge they have been abused by their partners, a new study confirms.

The study, led by Patricia O'Campo, director of the Centre for Inner City Research at St. Michael's Hospital, represents a major reversal of thinking about the value of universal screening programs for domestic abuse or intimate partner violence.

New York / Heidelberg, 7 March 2011A new study published in the Annals of Biomedical Engineering shows that a MEMS thermal sensor deployed by an angiogram catheter can detect the earliest stages of atherosclerosis. The MEMS thermal sensor used convective heat transfer to detect pre-atherosclerotic regions of arteries that otherwise showed no clinical signs of atherosclerosis.
