New drug-screening method yields long-sought anti-HIV compounds
Scientists at The Scripps Research Institute have used a powerful new chemical-screening method to find compounds that inhibit the activity of human immunodeficiency virus (HIV), the virus that causes AIDS. Unlike existing ...
A radar for ADAR: Altered gene tracks RNA editing in neurons
To track what they can't see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown ...
These bots were made for walking: Cells power biological machines
They're soft, biocompatible, about 7 millimeters long – and, incredibly, able to walk by themselves. Miniature "bio-bots" developed at the University of Illinois are making tracks in synthetic biology.

A healthy color: Testing for gum disease
Researchers at Temple University Maurice H. Kornberg School of Dentistry found that a color-changing oral strip is as effective in detecting periodontal disease as traditional methods, and is easier and less costly to administer.
UCSF creates fast, affordable tool for finding gene 'on-off' switches
UCSF scientists have created a method of quickly identifying large numbers of the genetic material known as short hairpin RNA — also called shRNA - that turns genes on and off.
Researcher proposes statistical method to enhance airport secondary security screenings
A researcher at The University of Texas at Austin has found that secondary security screening at airports is mathematically flawed, and has identified a way to select people for screenings more efficiently and fairly.
PSA test for men could get a second life for breast cancer in women
The widely known PSA blood test for prostate cancer in men may get a second life as a much-needed new test for breast cancer, the most common form of cancer in women worldwide, scientists are reporting in a new study in the ...
