The HIV/AIDS virus continues to ravage populations worldwide. Using a novel combination of optical techniques, researchers visualize how virus particles assemble and are released from infected cells to find new victims — knowledge which could lead to new technologies for inhibiting this process.

Scientists have discovered how the bacterial immune system works, and the finding could lead to new classes of targeted antibiotics, new tools to study gene function in microorganisms and more stable bacterial cultures used by food and biotechnology industries to make products such as yogurt and cheese.

The sperm of male fruit flies are coated with a chemical ’sex peptide’ which inhibits the female’s usual afternoon siesta and compels her into an intense period of foraging activity.

Drugs widely prescribed to treat facial paralysis in Bell’s palsy are ineffective and are based on false notions of the cause of the condition, according to researchers. They say research must now focus on discovering other potential causes and treatments.

Nuclear power could solve our energy problems but it has rather nasty by-products: radioactive waste. Not only the disposal of the old core rods but also reactor operation results in a large amount of low-level waste, especially contaminated cooling water. Scientists have now developed a new method to reduce the amount of this radioactive waste [...]

Purchasing prescription drugs in a three-month supply rather than a one-month supply has long been regarded as a way to save money. New research quantifies the savings for the first time.
New technology has given scientists the first look ever at RNA in a live bacteria cell — a sight that could offer new information about how the molecule moves and works.

Researchers are working to make the physical pain and discomfort of mammograms a thing of the past, while allowing for diagnostic imaging eventually to be done in a home setting.
