ASU researchers 'wire' DNA to identify mutations
A team of ASU researchers led by Nongjian Tao and Peiming Zhang has developed a new, breakthrough technique for the detection of DNA mutations.   view more (2005-12-09)

Size of brain structure could signal vulnerability to anxiety disorders
The size of a particular structure in the brain may be associated with the ability to recover emotionally from traumatic events. A new study by researchers from Massachusetts General Hospital (MGH) finds that an area called the ventromedial prefrontal cortex is thicker in volunteers who appear... view more (2005-07-12)

Bone marrow cells can become functional gut lining cells
Researchers report the discovery that cells used in bone marrow transplantation can develop into new cells lining the gut, according to a study by Yale School of Medicine in the Proceedings of the National Academy of Sciences.   view more (2006-03-03)

THE VALUE OF CYSTIC FIBROSIS SCREENING (p 789)
Research published in this week's issue of THE LANCET concludes that screening babies for cystic fibrosis provides the opportunity for more reliable prenatal diagnosis of the disease. The value of screening for the currently incurable disease cystic fibrosis has been the subject of debate over the... view more (2000-08-30)

It's not all the parent's fault -- Delinquency in children now linked to biology
A unique study appearing in the June issue of Psychological Science, a journal of the Association for Psychological Science, shows that, in children, a highly reactive autonomic nervous system, which regulates our cardiovascular, digestive and respiratory functions, paired with a stressful family... view more (2007-06-11)

Clues to gene expression in cystic fibrosis will guide research
Genetics tests could help provide cystic fibrosis (CF) patients with targeted treatment in future, pilot study authors suggest. Results from a French clinical trial published today in BMC Medicine show how a small percentage of CF sufferers with a rare genetic stop mutation responded positively to... view more (2007-03-29)

Hidden cues that make smokers light up
Smokers trying to kick the habit for 2004 are probably finding it much harder than they expected. New research by University of Sussex psychologists reveals that smokers subconsciously react to all sorts of visual cues that encourage them to light up. It's not just the obvious sight or smell of a... view more (2004-01-14)

Hot flashes underreported and linked to forgetfulness
Women in midlife underreport the number of hot flashes that they experience by more than 40 percent, and these hot flashes are linked to poor verbal memory, according to a study by researchers at the University of Illinois at Chicago.   view more (2008-06-17)

New design for transistors powered by single electrons
Scientists have demonstrated the first reproducible, controllable silicon transistors that are turned on and off by the motion of individual electrons.   view more (2006-02-03)

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... 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... view more (2008-04-03)

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... 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)
