Hotter summers may not be as catastrophic for the Greenland ice sheet as previously feared and may actually slow down the flow of glaciers, according to new research.
A letter published in Nature on 27 January explains how increased melting in warmer years causes the internal drainage system of the ice sheet to 'adapt' and accommodate more melt-water, without speeding up the flow of ice toward the oceans. The findings have important implications for future assessments of global sea level rise.
KNOXVILLE -- Four letter words may offend you more depending on which television channel you watch, according to a recent study out of Florida State University and the University of Tennessee, Knoxville.
DURHAM, N.H. – New research from the University of New Hampshire suggests that China should establish a unified supervisory agency, similar to what is used in Singapore, to oversee its complex financial sector.
A study published today in The Lancet Infectious Diseases finds that methods to protect pregnant women from malaria are still underutilised in sub-Saharan Africa (SSA). A review of national control strategies by a team of international researchers, led by the Malaria in Pregnancy Consortium and funded by the Consortium and the Wellcome Trust, has concluded that despite major efforts, coverage is still inadequate in many areas and needs to be scaled up.
The government's "nudge" approach to public health may struggle to make much impression on improving population health, warn experts on bmj.com today.
An accompanying editorial argues that the notion of nudging adds nothing to existing approaches and risks wasting resources.
BOSTON, Mass. (Jan. 26, 2011)—As news outlets throughout Europe and the U.S. report on the plummeting health of Western adults and children, there is no shortage of culprits. One villain often bandied about is the "fee for service" system of incentives for physicians. Clearly, if doctors are financially rewarded for simply performing more procedures, costs will soar at the expense of patient health.
Patients who had an ischemic stroke and were admitted to hospitals designated as primary stroke centers had a modestly lower risk of death at 30 days, compared to patients who were admitted to non-designated hospitals, according to a study in the January 26 issue of JAMA.
COLUMBUS, Ohio – Ohio State University researchers recently tested the merits of two new dishware sanitizers, and found them more effective at removing bacteria from restaurant dishes than traditional sanitizers.
Melvin Pascall, co-author of the study and associate professor of food science and technology at Ohio State, said that the two new sanitizers reflect the industry's recent efforts to develop more effective germ killers that are also environmentally friendly.
In regenerative medicine, large supplies of safe and reliable human embryonic stem (hES) cells are needed for implantation into patients, but the field has faced challenges in developing cultures that can consistently grow and maintain clinical-grade stem cells.
Standard culture systems use mouse "feeder" cells and media containing bovine sera to cultivate and maintain hES cells, but such animal product–based media can contaminate the cells. And because of difficulties in precise quality control, each batch of the medium can introduce new and unwanted variations.
Soap bubbles and films have always fascinated children and adults, but they can also serve to solve complex mathematical calculations. This is shown by a study carried out by two professors at the University of Málaga, who have succeeded in solving classic problems using just such an innovative procedure.
Light-emitting diodes (LEDs) are an increasingly popular technology for use in energy-efficient lighting. Researchers from North Carolina State University have now developed a new technique that reduces defects in the gallium nitride (GaN) films used to create LEDs, making them more efficient.
The nation’s history of heavy smoking is a major reason why lifespans in the U.S. fall short of those in many other high-income nations, and evidence suggests that current obesity levels also play a substantial part, says a new report from the National Research Council.
In the aftermath of a dirty bomb, hundreds or even thousands of victims could require medical attention. First responders conduct extensive training to prepare for such a cataclysmic event, but planning is difficult without a solid estimate of how many people could be injured.
Congresswomen consistently outperform their male counterparts on several measures of job performance, according to a recent study by University of Chicago scholar Christopher Berry.
The research comes as the 112th Congress is sworn in this month with 89 women, the first decline in female representation since 1978. The study authors argue that because women face difficult odds in reaching Congress – women account for fewer than one in six representatives – the ones who succeed are more capable on average than their male colleagues.
