Genetic risk factors identified for sudden cardiac death
An international science consortium with Dr. Arne Pfeufer of Helmholtz Zentrum Muenchen at its head has identified common gene variants in the human genome which influence the electrical activity of the heart muscle in humans and thus can be linked to cardiac arrhythmias and sudden cardiac death.

Special gold nanoparticles show promise for 'cooking' cancer cells
Researchers have developed the first hollow gold nanospheres -- smaller than the finest flecks of dust -- that search out and

Blue light specials
PNNL researchers have designed new host materials for a blue phosphorescent OLED that boost efficiency by at least 25 percent and help solve

Covering the bases: Quantum effect may hold promise for low-cost DNA sequencing, sensor applications
A ghostly property of matter, called quantum tunneling, may aid the quest for accurate, low-cost genomic sequencing, according to a new paper in Nature Nanotechnology Letters by Stuart Lindsay and his collaborators at the Biodesign Institute of Arizona State University.

U-M researcher's idea jells into potential new disease-detection method
Relying on principles similar to those that cause Jell-O to congeal into that familiar, wiggly treat, University of Michigan researchers are devising a new method of detecting nitric oxide in exhaled breath.

Proteins from garden pea may help fight high blood pressure, kidney disease
Researchers in Canada are reporting that proteins found in a common garden pea show promise as a natural food additive or new dietary supplement for fighting high blood pressure and chronic kidney disease.

First automated carbohydrate 'assembly line' opens door to new field of medicine
Scientists from Germany today reported a major advance toward opening the doors of a carbohydrate-based medicine chest for the 21st century.

TV crime drama compound highlights immune cells' misdeeds
Detectives on television shows often spray crime scenes with a compound called luminol to make blood glow.

Clinical trial backs use of special yogurt to fight stomach ulcer bacteria
A new type of yogurt appears to benefit your gut.

Hopkins scientists ID 10 genes associated with a risk factor for sudden cardiac death
That an abnormality in his heart's electrical system had managed to stay on the Q.T.

Education slowing AIDS in sub-Saharan Africa
Increased schooling across sub-Saharan Africa may be lowering new HIV infections among younger adults, according to sociologists, suggesting a shift in a decades-long trend where formal education is considered an AIDS risk factor.

Hollow gold nanospheres show promise for biomedical and other applications
A new metal nanostructure developed by researchers at the University of California, Santa Cruz, has already shown promise in cancer therapy studies and could be used for chemical and biological sensors and other applications as well.

10 genes identified in connection with sudden cardiac death
You're sitting at your desk and suddenly your heart is beating in overdrive or worse, lurching along like a car on fumes.

Confusion, not cheating, major factor in plagiarism among some students
Confusion about what constitutes plagiarism -- not malicious intent -- is the leading cause of plagiarism at the graduate school level, according to an expert who will describe the increasingly worrisome problem during a presentation at the National Meeting of the American Chemical Society.
