Catalysis discovery takes aim at NOx emissions
A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific Northwest National Laboratory have recorded the first observations of how certain catalyst... view more (2008-02-25)

Erectile dysfunction in diabetes is due to selective defect in the brain
A new study sheds additional light on how erectile dysfunction (ED) interacts with diabetes. The study is another step in uncovering the link between the two disorders, and may lead to improved efficacy in treatments.   view more (2007-03-16)

New cocoa evidence on why plant foods are beneficial to cardiovascular health
While a growing number of studies has shown a link between flavanol-rich cocoa and cardiovascular health, scientists have now substantiated a causal relationship between specific compounds present in cocoa and cardiovascular health.   view more (2006-01-17)

Fat overrides effects of vitamin C
Fats in our stomach may reduce the protective effects of antioxidants such as vitamin C. Scientists at the University of Glasgow found that in the presence of lipid the ability of antioxidants, such as ascorbic acid (the active component of vitamin C), to protect against the generation of potential... view more (2007-04-02)

Scientists using laser light to detect potential diseases via breath samples, says new study
By blasting a person's breath with laser light, scientists from the National Institute of Standards and Technology and the University of Colorado at Boulder have shown that they can detect molecules that may be markers for diseases like asthma or cancer.   view more (2008-02-19)

New iron-based and copper-oxide high-temperature
In the initial studies of a new class of high-temperature superconductors discovered earlier this year, research at the Commerce Department's National Institute of Standards and Technology (NIST) has revealed that new iron-based superconductors share similar unusual magnetic properties with... view more (2008-05-29)

Aquaporin and obesity
Dr. Gema Fr√ºhbeck, director of the Metabolic Research Laboratory of the University Hospital of the University of Navarra, has published a commentary in the latest issue of Nature.   view more (2005-12-21)

Therapeutic role found for carbon monoxide
In a medical case of Jekyll and Hyde, carbon monoxide - the highly toxic gas emitted from auto exhausts and faulty heating systems - has proven effective in treating the symptoms of pulmonary arterial hypertension (PAH), an extremely debilitating condition that typically leads to right heart... view more (2006-09-19)

Viagra for alleviation of pulmonary hypertension?
Results of a preliminary study in this week's issue of THE LANCET suggest that Viagra may have a future role in the treatment of pulmonary hypertension (increased blood pressure in the pulmonary artery), a severe and potentially fatal condition causing respiratory impairment. Lung fibrosis... view more (2002-09-18)

New efficiency record for solar cells
The efficiency improvement is achieved by the use of an ultra-thin aluminum oxide layer at the front of the cell, and it brings a breakthrough in the use of solar energy a step closer.   view more (2008-05-15)

Double Duty: Loss of Protective Heart Failure Protein Causes High Blood Pressure
Scientists at the Center for Translational Medicine at Thomas Jefferson University in Philadelphia have found that a protein that appears to have protective and perhaps healing effects for failing hearts also plays a similar role in high blood pressure.   view more (2008-05-06)

Laser light may be able to detect diseases on the breath
A team of scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) at Boulder, has shown that by sampling a person's breath with laser light they can detect molecules in the breath that may be markers for diseases like... view more (2008-02-19)

Blocking previously unrecognized links between inflammatory systems could make COX-2 inhibitors safe
A recently identified path of inflammation once thought to be wholly independent of other inflammatory systems has now been linked to another major pathway.   view more (2005-12-23)

Researchers Find Controls to Gold Nanocatalysis
Researchers at the Georgia Institute of Technology have made a discovery that could allow scientists to exercise more control over the catalytic activity of gold nanoclusters.   view more (2006-08-10)

Problem: Implant Infection. Solution: Nanotech Surfaces
Orthopaedic implants help millions of Americans stay active. But these medical devices are prone to infection, forcing patients back to surgery for repair or replacement. Now, for the first time, a team of engineers has shown that zinc or titanium oxide nanosurfaces can reduce the presence of... view more (2006-07-10)

The End of the Line for Silicon Dioxide?
By means of computer simulations, scientists at the Technical Universities in Clausthal and Vienna are investigating new materials for even smaller and more efficient transistor generations. The smaller the transistors, the faster they can operate. As a result, faster and faster processors can also... view more (2003-12-23)

Russian Filter For Russian Exhausts
Automobiles manufactured in Russia are now often equipped with expensive American or European catalytic exhaust scrubbers - converters. However, according the opinion of researchers from the Mendeleyev Russian Chemical-Engineering University, Russian automobiles will be soon equipped with exhaust... view more (2004-06-15)

Stopping statins after stroke raises risk of death, dependency
People who stopped taking cholesterol-lowering drugs after being hospitalized for a stroke are at greater risk of death or dependency within three months of the stroke.   view more (2007-08-28)

INTELLIGENT ANTI-CORROSION COATING GIVES TURBINES IMPROVED PROTECTION
British materials scientists have invented a revolutionary new protective coating for high performance industrial and marine gas turbines. The new system called Smartcoat, can adapt to different types of corrosion modifying its chemical structure in response. The new coating can protect turbines in... view more (1999-09-09)

Study explains unexpected conductivity of nanoscale silicon
When graduate student Pengpeng Zhang successfully imaged a piece of silicon just 10 nanometers-or a millionth of a centimeter-in thickness, she and her University of Wisconsin-Madison co-researchers were puzzled.   view more (2006-02-09)

Children of diabetics show signs of atherosclerosis
The blood vessels of people whose parents both have type 2 diabetes do not respond as well to changes in blood flow as those of people without a family history of diabetes, even if they do not have diabetes themselves.   view more (2006-06-21)

New lights on the pathogenic mechanisms of liver cirrhosis with ascites
The pathogenic mechanisms implicated in the failure of intestinal barrier in cirrhosis have not been fully elucidated as yet and remains to be investigated.   view more (2008-09-24)

Erectile dysfunction related to sleep apnea may persist, but is treatable
For sufferers of sleep apnea, erectile dysfunction (ED) is often part of the package. New research indicates that ED in cases of obstructive sleep apnea syndrome (OSAS) may be linked to the chronic intermittent hypoxia-oxygen deprivation- (CIH) that patients with OSAS experience during episodes of... view more (2008-09-12)
