Researchers have discovered that a key protein implicated in Alzheimer's disease is produced in the brain at a normal rate but is not removed efficiently. The finding may lead to improved tests for early diagnosis and new approaches for treating this devastating disorder.
Buprenorphine, a promising treatment for opioid-addicted pregnant women, reduces withdrawal-related symptoms to their newborns better than standard methadone therapy, a new clinical trial shows.
New research has identified a protein that helps bacteria break away from medical devices like catheters and spread throughout the body. The finding gives insight into how bacterial communities called biofilms cause disease and provides a potential target for future treatments.

Researchers have isolated a bacterium that can use arsenic instead of phosphorus to sustain its growth. The discovery could fundamentally affect how we define life.
Researchers have developed a method for detecting prions that may lead to a practical test for diagnosing the fatal brain conditions caused by these infectious agents.
A protein lost in Alzheimer’s disease may play a key role in memory development, according to a new study in mice. The findings give insight into how brain signals are disrupted by the disease and offer a potential new treatment target.

A pill that’s currently used to treat HIV infection can also greatly reduce the risk of acquiring HIV among at-risk men. The finding, from a large clinical trial, represents a major advance toward HIV prevention.
Kidney patients fare better on an almost-daily hemodialysis regimen than on the standard 3-times-a-week plan, according to a new study.
Researchers have reversed age-related degeneration in a mouse model of aging. While the findings don't prove that natural aging could be halted or reversed, they may lead to new strategies to combat certain age-related conditions.
