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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
