'Strained' quantum dots show new optical properties
Quantum dots, tiny luminescent particles made of semiconductors, hold promise for detecting and treating cancer earlier. However, if doctors were to use them in humans, quantum dots could have limitations related to their size and possible toxicity. view more (2008-12-08)
HIV treatments improve health, but nutritional issues remain
Despite the success of highly active antiretroviral treatment (HAART), people with HIV may still be at higher risk for nutritional deficiencies and abnormalities. view more (2006-12-26)
Stunning finding: Compounds protect against cerebral palsy
Two compounds developed by Northwestern University chemists have been shown to be effective in pre-clinical trials in protecting against cerebral palsy, a condition caused by neurodegeneration that affects body movement and muscle coordination. view more (2009-02-25)
New fertilizer SRM can help control heavy metal content
A new reference material developed by the National Institute of Standards and Technology (NIST) can help the agriculture industry and state regulators monitor the concentrations of several potentially hazardous heavy metal contaminants in fertilizers. view more (2006-10-13)
Use of statins shows improvement in erectile performance of some men
Researchers at the University of Pennsylvania School of Medicine say preliminary results of a small study show promise in improving erectile dysfunction (ED) in men who had shown minimal reaction to Viagra. view more (2006-02-22)
'Hot' oxygen atoms on titanium dioxide motivated by more than just temperature
Like two ballroom dancers waltzing together, the two atoms of an oxygen molecule severed by a metal catalyst usually behave identically. But new research reveals that on a particular catalyst, split oxygen atoms act like a couple dancing the tango: one oxygen atom plants itself while the other shimmies away, probably with energy partially stolen... view more...

Embryo's heartbeat drives blood stem cell formation
Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood. view more (2009-05-14)
Methane-eating microbes can use iron and manganese oxides to 'breathe'
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. view more (2009-07-10)
Silica smart bombs deliver knock-out to bacteria
Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. view more (2008-02-26)
Elevated arginase levels contribute to vascular eye disease such as diabetic retinopathy
Elevated levels of the enzyme arginase contribute to vascular eye damage and Medical College of Georgia researchers say therapies to normalize its levels could halt progression of potentially blinding diseases such as diabetic retinopathy. view more (2009-08-18)
Portable and precise gas sensor could monitor pollution and detect disease
In the air, it is a serious pollutant. In the body, it plays a role in heart rate, blood flow, nerve signals and immune function. view more (2009-09-21)
Military imagery analysis assistant
Friend or enemy - what kind of tank or ship can be seen in aerial or satellite photo? The RecceMan identification assistant, which helps recognize the most diverse objects quickly and accurately, is the first interactive image recognition system produced for the German army. view more (2001-12-03)
Snails snack on poison metals
SOILS tainted with heavy metals from industrial pollution and sewage sludge may poison organisms that live in the soil far more readily than thought. The finding raises fears that unexpectedly high levels of toxins are getting into the food chain. Contaminated soils are given hazard ratings that are based on the key assumption that organisms can... view more... (2002-12-18)
Researchers find new mechanism governing particle growth in nanocomposites
A research team from the Georgia Institute of Technology and Drexel University has discovered a surprising new mechanism by which polymer materials used in nanocomposites control the growth of particles. view more (2005-09-01)
More Than Meets the Eye: New Blue Light Nanocrystals
Berkeley Lab researchers have produced non-toxic magnesium oxide nanocrystals that efficiently emit blue light and could also play a role in long-term storage of carbon dioxide, a potential means of tempering the effects of global warming. view more (2009-07-22)
New technology shows promise against resistant staph infections
Scientists at Albert Einstein College of Medicine of Yeshiva University have combined their revolutionary new drug-delivery system with a powerful antimicrobial agent to treat potentially deadly drug-resistant staph infections in mice. view more (2009-05-01)
The clear future of electronics
A group of scientists at Korea Advanced Institute of Science and Technology (KAIST) has fabricated a working computer chip that is almost completely clear -- the first of its kind. view more (2008-12-10)
New study shows Concord grape juice has a heart-healthy effect not yet reported with red wine
Many studies have suggested that moderate red wine consumption is beneficial to cardiovascular health. But what if you'd like to skip the alcohol? view more (2007-10-03)
Cell splits water via sunlight to produce hydrogen
Engineers at Washington University in St. Louis have developed a unique photocatalytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. view more (2007-05-03)
Nitrates in vegetables protect against gastric ulcers
Fruits and vegetables that are rich in nitrates protect the stomach from damage. This takes place through conversion of nitrates into nitrites by the bacteria in the oral cavity and subsequent transformation into biologically active nitric oxide in the stomach. view more (2008-05-08)
