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)
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)
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)
Common bacteria pirate natural mechanism to get inside cells
Bacteria and viruses utilize a natural mechanism to get inside cells and grow, researchers say. view more (2006-01-26)
Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness
A naturally occurring molecule in the body appears to control whether certain medications, such as beta adrenergic receptor agonists used in acute heart failure or in inhalers for asthma, lose their effectiveness over time. view more (2007-05-04)
Super sensitive gas detector goes down the nanotubes
When cells are under stress, they blow off steam by releasing minute amounts of nitrogen oxides and other toxic gases. view more (2009-01-14)
Ammonia-loving archaea win landslide majority
A genetic analysis of soil samples indicates that a group of microorganisms called crenarchaeota are the Earth's most abundant land-based creatures that oxidize ammonia. view more (2006-08-17)
Scientists help explain effects of ancient Chinese herbal formulas on heart health
New research at The University of Texas Health Science Center at Houston suggests that ancient Chinese herbal formulas used primarily for cardiovascular indications including heart disease may produce large amounts of artery-widening nitric oxide. view more (2009-08-19)
New synthetic compounds appear to prevent brain cell death
Spanish chemists have developed a promising set of synthetic compounds that one day could help slow or perhaps halt the progression of Alzheimer's disease and other neurological disorders. view more (2005-12-21)
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 bacteria, a technique that can be applied to implants... view more...

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 be designed. The function of a transistor... view more... (2003-12-23)
ESC Congress 2004: PERTINENT - PERindopril - Thrombosis, InflammatioN, Endothelial dysfunction and Neurohormonal activation Trial
A Sub-Study of the EUROPA Study Evaluation of the Effect of Perindopril on Endothelial Function view more (2004-08-31)
New light shed on marine luminescence
The phenomenon of light emission by living organisms, bioluminescence, is quite common, especially in marine species. view more (2009-02-23)
U-M study offers new perspective on nitric oxide signaling in rheumatoid arthritis
Scientists at the University of Michigan Medical School have found evidence that challenges current thinking about the cause of rheumatoid arthritis (RA), a chronic inflammatory disease that damages joints, causes pain, loss of movement, and bone deformities in 2.1 million Americans. view more (2006-10-31)
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 a wide range of different corrosion scenarios,... view more... (1999-09-09)
'Erectile dysfunction' drugs heighten natural anti-cancer activity
Sildenafil and other "impotence drugs" that boost the production of a gassy chemical messenger to dilate blood vessels and produce an erection now also show promise in unmasking cancer cells so that the immune system can recognize and attack them, say scientists at the Johns Hopkins Kimmel Cancer Center. view more (2006-12-08)
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)
Estrogen activates critical lung genes to improve lung function following preterm birth
Estrogen may be a new postnatal therapy to improve lung function and other outcomes in preterm infants, researchers at UT Southwestern Medical Center have found in an animal study. view more (2009-03-12)
