NIST develops rapid method for judging nanotube purity
Researchers at the National Institute of Standards and Technology (NIST) have developed a sensitive new method for rapidly assessing the quality of carbon nanotubes. view more (2007-02-02)
Computer simulations point to key molecular basis of cystic fibrosis
Researchers from the University of North Carolina at Chapel Hill have identified a key molecular mechanism that may account for the development of cystic fibrosis, which about 1 in 3000 children are born with in the US every year. view more (2008-03-03)
Scientists discover basic defect in cystic fibrosis airway glands
Scientists at Stanford University have determined that the buildup of sticky mucus found in cystic fibrosis is caused by a loss in the epithelial cell's ability to secrete fluid. view more (2006-03-20)
Tracking Cystic Fibrosis with Mice: DFG fellow develops an animal model for the disease
Cystic fibrosis, also known as mucoviscidosis, is one of the most common genetic diseases with a fatal outcome in western Europe. The disease is caused by a defective gene that affects the salt and fluid composition of respiratory tract secretions. As a result, they become highly viscous. The viscous mucous then clumps in the smaller lung... view more... (2004-04-26)
Experiments point to new treatments for PKD
A family of small molecules called CFTR inhibitors show promising effects in slowing the progression of polycystic kidney disease (PKD), the most common genetic disease of the kidneys, according to preliminary research reported in the July 2008 issue of the Journal of the American Society Nephrology. view more (2008-04-03)
Paperwork: Buckypapers clarify electrical, optical behavior of nanotubes
Using highly uniform samples of carbon nanotubes-sorted by centrifuge for length-materials scientists at the National Institute of Standards and Technology (NIST) have made some of the most precise measurements yet of the concentrations at which delicate mats of nanotubes become transparent, conducting sheets. view more (2008-10-16)
Frozen lightning: NIST's new nanoelectronic switch
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a prototype nanoscale electronic switch that works like lightning—except for the speed. view more (2007-03-05)
Mayo Clinic Cancer Center finds possible genetic link to pancreatic cancer
Mayo Clinic researchers have found the risk of developing pancreatic cancer at a young age (under 60) to be twice as high for people who carry a mutation of the gene that causes cystic fibrosis, compared to noncarriers. view more (2005-10-21)
Quantized heat conduction by photons observed
In a recent experiment, to be published in Nature on November 9, Dr Matthias Meschke and professor Jukka Pekola, together with Dr Wiebke Guichard, a coworker from French CNRS, investigated heat exchange between two small pieces of normal metal, connected to each other only via superconducting leads. The results demonstrate that at very low... view more... (2006-11-10)
Researchers win money to develop breath test to detect breast cancer
One of the biggest problems in fighting breast cancer is the lack of inexpensive, early detection diagnostic tools. view more (2006-04-04)
The amazing maze of maize evolution
Understanding the evolution and domestication of maize has been a holy grail for many researchers. As one of the most important crops worldwide and as a crop that appears very different from its wild relatives as a result of domestication, understanding exactly how maize has evolved has many practical benefits and may help to improve crop yields. view more (2009-10-05)
Study reveals how cells destroy faulty proteins in cystic fibrosis
The cellular system that degrades faulty proteins created by the cystic fibrosis gene has been identified by University of North Carolina at Chapel Hill scientists. view more (2006-08-11)
NYU, Rutgers study shows how using mental strategies can alter the brain's reward circuitry
The cognitive strategies humans use to regulate emotions can determine both neurological and physiological responses to potential rewards, a team of New York University and Rutgers University neuroscientists has discovered. view more (2008-06-30)
ORNL finding could help electronics industry enter new phase
Electronic devices of the future could be smaller, faster, more powerful and consume less energy because of a discovery by researchers at the Department of Energy's Oak Ridge National Laboratory. view more (2009-06-18)
Ultrafast laser spectrometer measures heat flow through molecules
Global warming isn't the only heat scientists are feeling. Another area in which heat flow is becoming crucial is the field of molecular electronics, where long-chain molecules attached to tiny electrodes are used to transport and switch electrons. view more (2007-08-10)
Botanicals have no effect on hot flashes or cognition: Study
Two studies conducted by researchers at the University of Illinois at Chicago and Northwestern University have found that commonly used botanicals do not have an effect on hot flashes or on cognitive function in menopausal women. view more (2009-08-07)
DNA sieve -- Nanoscale pores can be tiny analysis labs
Imagine being able to rapidly identify tiny biological molecules such as DNA and toxins using less than a drop of salt water in a system that can fit on a microchip. view more (2007-05-14)
Physicists tailor magnetic pairings in nanoscale semiconductors
Electrons love to zip around metals such as copper, especially if the metal is cooled to temperatures near absolute zero. But if they encounter a magnetic atom (say, iron) during their travels, the electrons will try to "screen," or cancel out, the magnetic atom's spin alignment by pairing with it. This pairing modifies the flow of... view more... (2007-03-15)
