Concrete less sensitive for cracks than previously thought
Reinforced high-strength concrete can crack due to stresses that develop during the hardening process. However, this has been found to be surprisingly less quick than previously thought. Due to Dutch research, extra steps during the hardening process can be omitted. This will result in cheaper concrete. view more (2003-03-21)
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)
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 materials used in emission control devices are... view more...

Cutaneous application of nanoparticles offers hope for treatment of erectile dysfunction
Cutaneous application of nanoparticles may offer a new means of delivering drugs to treat erectile dysfunction (ED), according to findings presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA). view more (2009-04-27)
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 cancer-forming compounds in the stomach is less... view more...

A missing enzyme conveys major heart protection in pre-clinical work
Mice born without a certain enzyme can resist the normal effects of a heart attack and retain nearly normal function in the heart's ventricles and still-oxygenated heart tissue, according to a study by researchers at Duke University Medical Center. view more (2009-03-31)
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)
Aquaporin and obesity
Dr. Gema Fr√°hbeck, 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)
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 previously known superconducting copper-oxide materials. view more (2008-05-29)
What do blood stem cells need to grow? Blood flow
Blood stem cells literally go with the flow, according to a new report published as an immediate early publication in the journal Cell, a Cell Press journal, on May 13th. view more (2009-05-14)
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 failure and eventual death. 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 (scarring of the lungs due to inflammation of the... view more... (2002-09-18)
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)
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)
Therapeutic nanoparticles give new meaning to sugar-coating medicine
A research team at the National Institute of Standards and Technology (NIST) studying sugar-coated nanoparticles for use as a possible cancer therapy has uncovered a delicate balancing act that makes the particles more effective than conventional thinking says they should be. view more (2009-09-23)
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 asthma or cancer. 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)
Aluminum-oxide nanopore beats other materials for DNA analysis
Fast and affordable genome sequencing has moved a step closer with a new solid-state nanopore sensor being developed by researchers at the University of Illinois. view more (2009-06-03)
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)
