Physician practice interactions with health plans cost $31 billion a year

Bethesda, MD—As policymakers consider ways to cut health costs as a part of health reform, a new national survey of physician practices finds that physicians on average are spending the equivalent of three work weeks annually on administrative tasks required by health plans. According to the study by Lawrence P. Casalino, M.D., Ph.D., of Weill Cornell Medical College and colleagues, physician practices report that overall the costs of interacting with insurance plans is $31 billion annually and 6.9 percent of all U.S. expenditures for physician and clinical services.

Study finds virtual doctors visits satisfactory for both patients and clinicians

BOSTON – Travelers book plane tickets online, bank customers can check their accounts at any computer, and busy families can grocery shop online. Someday, even doctor visits could be among the conveniences offered via the Internet. Researchers considering the feasibility and effectiveness of virtual doctors visits report that patients and physicians found that evaluations done through videoconferencing were similar to face-to-face visits on most measures, according a study published in the May issue of the Journal of Telemedicine and Telecare.

New fuel cell catalyst uses 2 metals

Material scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two to five times more effective than commercial catalysts. The novel technique eventually will enable a cost effective fuel cell technology, which has been waiting in the wings for decades, and should give a boost for cleaner use of fuels worldwide.

Graphene yields secrets to its extraordinary properties

Applying innovative measurement techniques, researchers from the Georgia Institute of Technology and the National Institute of Standards and Technology (NIST) have directly measured the unusual energy spectrum of graphene, a technologically promising, two-dimensional form of carbon that has tantalized and puzzled scientists since its discovery in 2004.

Study finds link between individual stress and adolescent obesity

AMES, Iowa -- Stress may indeed be a direct contributor to childhood obesity. That's according to a new Iowa State University study finding that increased levels of stress in adolescents are associated with a greater likelihood of them being overweight or obese.

U of I study: More support needed for families adopting from foster care

URBANA – A new University of Illinois study of families adopting from foster care revealed significant declines in professional services and social support over the first three years of adoptive family life, even though parents indicated that they need continued assistance.

"Children who have been in foster care can have a host of medical issues and a history of multiple placements so parenting them can be a challenging task for adoptive parents," said Laurie Kramer, a U of I associate dean and professor of applied family studies.

Huygens sets a new Go world record

At the Taiwan Open 2009, held in Taiwan from Feb. 10-13, the Dutch national supercomputer Huygens, which is located at SARA Computing and Networking Services in Amsterdam, defeated two human Go professionals in an official match.

Mothers give interloper's offspring a head start in life

A new study has revealed that mother birds can provide an early advantage to the chicks that they have sired with their non-social partner (known as extra-pair offspring).

It has long been known that female birds commonly mate with males other than their social partner, producing broods of mixed paternity in which the interloper's 'extra pair' offspring often outperform their half brothers and sisters.

Would NHS staff go to work during a flu pandemic?

A survey of health care workers has revealed that as many as 85% may stay off work if an influenza pandemic did take hold of the country. The results of the survey, published in the open access journal BMC Public Health, suggest that levels of absenteeism may be significantly higher than current official estimates and that 'willingness', rather than 'ability', plays the largest role in health care workers' decisions as to whether to go to work or not.

University of Arizona research on scorpion antivenom published in NEJM

TUCSON, Ariz. --Youngsters suffering severe nerve poisoning following a scorpion sting recover completely and quickly if a scorpion-specific antivenom is administered, according to a study conducted by researchers from The University of Arizona and reported in the May 14 issue of The New England Journal of Medicine.

Natural petroleum seeps release equivalent of eight to 80 Exxon Valdez oil spills

A new study by researchers at Woods Hole Oceanographic Institution (WHOI) and the University of California, Santa Barbara (UCSB) is the first to quantify the amount of oil residue in seafloor sediments that result from natural petroleum seeps off Santa Barbara, California.

The new study shows the oil content of sediments is highest closest to the seeps and tails off with distance, creating an oil fallout shadow. It estimates the amount of oil in the sediments down current from the seeps to be the equivalent of approximately 8-80 Exxon Valdez oil spills.

Scientists document fate of oil slicks from natural seeps

Twenty years ago, the oil tanker Exxon Valdez was exiting Alaska's Prince William Sound when it struck a reef in the middle of the night.

What happened next is considered one of the nation's worst environmental disasters: 10.8 million gallons of crude oil spilled into the pristine Alaskan waters, eventually covering 11,000 square miles of ocean.

Now, imagine 8 to 80 times the amount of oil spilled in the Exxon Valdez accident.

New testing facility helps researchers improve land mine detection equipment

Researchers at the Georgia Institute of Technology have built a test facility to evaluate and enhance sensors designed to detect buried land mines. The unique automated system measures the response of individual electromagnetic induction sensors or arrays of sensors against land mines buried at many possible angles.
