New guidelines for postoperative nausea and vomiting
After five years of reviewing the latest research findings, a panel of experts led by a Duke University Medical Center anesthesiologist has developed new guidelines to help physicians reduce the occurrence of nausea and vomiting in patients after surgery. view more (2006-10-17)
Pulmonary hypertension in children may result from reduced activity of gene regulator
Too little activity by gene regulators called PPARs appears to be a major player in the irreversible lung damage that can occur in children with heart defects, researchers say. view more (2009-03-06)
New Graphene-Based Material Clarifies Graphite Oxide Chemistry
A new "graphene-based" material that helps solve the structure of graphite oxide and could lead to other potential discoveries of the one-atom thick substance called graphene, which has applications in nanoelectronics, energy storage and production, and transportation such as airplanes and cars, has been created by researchers at The... view more...

Silicon Thin-Film Solar Cells Gaining In Efficiency
An important goal of modern energy research is to directly convert sunlight into electricity at low cost. Silicon thin-film solar cells promise comparatively lower costs than conventional solar cells. However, to become a mass product of the future, the efficiencies of large-area modules must climb from currently about 6 to 7 percent to 10 percent... view more... (2002-08-08)
Cause of gender differences in blood pressure, kidney damage under study
While men and women both get high blood pressure and related kidney disease, the path to get there is shorter, steeper and just different for men, researchers say. view more (2007-05-03)
iNOS expression may links chronic biliary inflammation to malignant transformation
It is well known that chronic biliary inflammation is a risk factor for biliary carcinogenesis. However, the molecular mechanisms of biliary carcinogenesis as a consequence of chronic biliary inflammation remain unclear. view more (2007-12-20)
Putting a Strain on Nanowires Could Yield Colossal Results
In finally answering an elusive scientific question, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the selective placement of strain can alter the electronic phase and its spatial arrangement in correlated electron materials. view more (2009-09-18)
Emission choices lead to starkly different futures for Northeast agriculture, says CU expert at briefing
Farmers will be the first to feel the heat from global warming as they grapple with new and aggressive crop pests, summer heat stress and other sobering challenges that could strain family farms to the limit, warns David Wolfe, a Cornell expert on the effects of climate change on agriculture. view more (2007-07-12)
MIT researchers build tiny batteries with viruses
MIT scientists have harnessed the construction talents of tiny viruses to build ultra-small "nanowire" structures for use in very thin lithium-ion batteries. view more (2006-04-07)
Study identifies another strategy for normalizing tumor blood supply
Manipulating levels of nitric oxide (NO), a gas involved in many biological processes, may improve the disorganized network of blood vessels supplying tumors, potentially improving the effectiveness of radiation and chemotherapy. view more (2008-02-21)
MIT researchers make carbon nanotubes without metal catalyst
Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. view more (2009-08-11)
VIP's importance to temperature regulation may be pre-empted by substance P
An elusive neurotransmitter pathway in the skin may have been isolated by University of Oregon researchers, a discovery that, if confirmed, would be a leap forward in understanding how temperature regulation occurs. view more (2006-10-25)
Soil emissions are much-bigger-than-expected component of air pollution
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation. view more (2005-06-07)
New ice cores expand view of climate history
Two new studies of gases trapped in Antarctic ice cores have extended the record of Earth's past climate almost 50 percent further, adding another 210,000 years of definitive data about the makeup of the Earth's atmosphere and providing more evidence of current atmospheric change. view more (2005-11-28)
Filter That Makes Viruses Adhere
Siberian researchers have developed a biologically active sorbent of a new generation. The sorbent provides for the 100-percent efficient water purification from microorganisms and bacteriophages. Microbiological researches were performed with partial support of the U.S. Civilian Research and Development Foundation (CRDF) grant. view more (2005-03-25)
Climate change threatens a million species with extinction
Climate change may drive a quarter of land animals and plants extinct, according to a major new study published in the journal Nature - unless greenhouse gas emissions are drastically reduced. The largest collaboration of scientists ever to apply themselves to this problem studied six biodiversity-rich regions around the world representing 20% of... view more... (2004-01-07)
Leveling the field for babies with persistent pulmonary hypertension
If he can figure out which babies will be born unable to breathe properly, Dr. Stephen M. Black thinks he can help change that. view more (2006-10-09)
Horphag's Prelox provides over-the-counter solution
For couples worldwide, erectile dysfunction (ED) is one of the leading contributors to a man's inability to perform. As millions of men in America each year look for a solution, many seek alternative treatments to prescription medications and surgery that may have dangerous side effects. view more (2007-12-04)
Robust sensor yields cleaner car exhaust
Emissions from cars have to be reduced further in order to meet today's environmental demands. A new and robust exhaust sensor developed by researchers at Linköping University in Sweden has proven to meter the consistency of exhaust gases extremely well and is now on its way to the market. view more (2005-04-27)
Nanohelix structure provides new building block for nanoscale piezoelectric devices
A previously-unknown zinc oxide nanostructure that resembles the helical configuration of DNA could provide engineers with a new building block for creating nanometer-scale sensors, transducers, resonators and other devices that rely on electromechanical coupling. view more (2005-09-09)
