Study Pinpoints Rare Molecular 'Transitions' As Possible Cause Of Skin 'Photoaging'
Experimenting with lasers, a biophysical chemistry team now at Duke University has discovered rare, hard-to-detect interactions between skin molecules and sunlight that eventually could cause the uncomplimentary changes characteristic of

Scientists Discover How Bacteria Protect Themselves Against Immune System
Scientists at Children's Hospital Medical Center of Cincinnati have discovered a major mechanism by which bacteria protect themselves against the human immune response - a discovery that opens the door for development of a new class of antibiotics to fight infection.

Guidelines Not Necessarily Guiding Physician Behavior, Study Says
An ounce of prevention may be worth a pound of cure, but many people with heart disease may not even get that much, say researchers.

UNC Scientists Succeed In Inserting Gene In Human Cells Via Artificial Chromosome
Using a promising new technique, University of North Carolina at Chapel Hill scientists have for the first time successfully inserted large circular plasmids - doughnut- shaped pieces of DNA containing healthy genes - into human cells and showed the genes functioned as if they belonged there.

Genetically Engineered Mice Show Characteristic Signs Of Alzheimer's, Could Be Ideal Tool For Testing New Therapies
Laboratory mice genetically engineered to have human apolipoprotein E4 (apoE4) in the brain, a protein associated with increased risk of Alzheimer's disease, show learning and memory problems strikingly similar to those seen in human Alzheimer's patients, according to researchers at the J.
