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.

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.

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.

Physicians will soon begin implanting a new device designed to improve breathing in patients with upper spinal-cord injuries or other diseases that keep them from breathing independently.

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.

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 considerably. They use small beads consisting of a special polymer which “fishes” the radioactivity out of the water.

From simple decisions like "Should I eat this brownie?" to bigger questions such as "Should my next car be a hybrid?" consumers are involved in an inner dialogue that reflects thoughts and perspectives of their different selves, according to the authors of a new study.

Ecologists have worked out a way of using recordings of birdsong to accurately measure the size of bird populations. This is the first time sound recordings from a microphone array have been translated into accurate estimates of bird species' populations. The new technique will also work with whale song and could lead to a major advance in our ability to monitor whale and dolphin numbers.

More studies that directly compare the effectiveness of different biologic drugs for rheumatoid arthritis are needed, say researchers who reviewed previous studies assessing the effectiveness of biologic disease-modifying drugs for treatment of RA and found that although all were very effective, there was little data on direct comparisons between the drugs that could help doctors decide which to prescribe.

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.
