Rutgers researchers identify materials that may deliver more 'bounce'

NEW BRUNSWICK, N.J. – Rutgers researchers have identified a class of high-strength metal alloys that show potential to make springs, sensors and switches smaller and more responsive.

The alloys could be used in springier blood vessel stents, sensitive microphones, powerful loudspeakers, and components that boost the performance of medical imaging equipment, security systems and clean-burning gasoline and diesel engines.

New molecular robot can be programmed to follow instructions

Scientists have developed a programmable "molecular robot" — a sub-microscopic molecular machine made of synthetic DNA that moves between track locations separated by 6nm. The robot, a short strand of DNA, follows instructions programmed into a set of fuel molecules determining its destination, for example, to turn left or right at a junction in the track. The report, which represents a step toward futuristic nanomachines and nanofactories, appears in ACS's Nano Letters.

How do people respond to being touched by a robot?

For people, being touched can initiate many different reactions from comfort to discomfort, from intimacy to aggression. But how might people react if they were touched by a robot? Would they recoil, or would they take it in stride? In an initial study, researchers at the Georgia Institute of Technology found people generally had a positive response toward being touched by a robotic nurse, but that their perception of the robot's intent made a significant difference. The research is being presented today at the Human-Robot Interaction conference in Lausanne, Switzerland.

Toward real time observation of electron dynamics in atoms and molecules

Quebec City, March 9, 2011 – Another step has been taken in matter imaging. By using very short flashes of light produced by a technology developed at the national infrastructure Advanced Laser Light Source (ALLS) located at INRS University, researchers have obtained groundbreaking information on the electronic structure of atoms and molecules by observing for the first time ever electronic correlations using the method of high harmonic generation (HHG).

Massachusetts reform hasn't stopped medical bankruptcies: Harvard study

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.

Trauma patients have higher rate of death for several years following injury

In a study that included more than 120,000 adults who were treated for trauma, 16 percent of these patients died within 3 years of their injury, compared to an expected population mortality rate of about 6 percent, according to a study in the March 9 issue of JAMA. The researchers also found that trauma patients who were discharged to a skilled nursing facility had a significantly increased risk of death compared with patients discharged home without assistance.

Chronic disease care poorer in nursing and residential homes under GP target scheme

The quality of chronic disease care under the GP pay for performance system is poorer for residents of care homes than those living in the community, according to a study published on bmj.com today.

The Quality and Outcomes Framework (QOF) for general practice is a voluntary system of financial incentives, which has been in place since 2004. Part of the programme includes specific targets for GPs to demonstrate high quality care for patients with chronic diseases.

Health Bill unlikely to improve children's health services, warn child health experts

The coalition government's Health and Social Care Bill is a missed opportunity to deliver the improvements in children's health services in England that are urgently needed, warn experts in a paper published on bmj.com today.

Ingrid Wolfe and some of the country's leading experts in child health propose a fundamentally different way of delivering children's health care that is long overdue in the UK.

Academic performance of UK doctors and medical students varies by ethnicity

UK trained doctors and medical students from minority ethnic groups tend to underperform academically compared with their white counterparts, finds a study published on bmj.com today.

This attainment gap has persisted for many years and must be tackled to ensure a fair and just method of training and assessing current and future doctors, say the authors.

Enzymes from garden compost could favour bioethanol production

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.

Big games, close scores lead to more auto fatalities for winning fans

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.

How can robots get our attention?

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.

Boston researchers create 'SMArt' platform architecture, launch $5,000 health app competition

Boston, Mass. – Through a grant from the Office of the National Coordinator for Health Information Technology (ONC), researchers at Children's Hospital Boston and Harvard Medical School have developed a first-of-its kind platform architecture to support a flexible health information technology (IT) environment and promote innovation.

Aging with grace: In-home assessments lead to better care, lower health costs

INDIANAPOLIS – The March 2011 issue of the journal Heath Affairs highlights an evidence-based model of geriatric care management developed, implemented and tested by researchers and clinicians from Indiana University, the Regenstrief Institute and Wishard Health Services.
