Alzheimer’s Disease May Stem from Protein Clearance Problem

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.

Treatment for Addicted Moms Has Better Outcomes for Babies

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.

Preventing Bacterial Infections from Medical Devices

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.

Bacteria Can Grow Using Arsenic

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.

Early Prion Detection May Be Possible

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.

Insight into Memory Loss in Alzheimer’s Disease

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.

Daily Drug Reduces Risk for HIV Infection

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.

More Frequent Dialysis Improves Health of Kidney Patients

Kidney patients fare better on an almost-daily hemodialysis regimen than on the standard 3-times-a-week plan, according to a new study.

Aspects of Aging Might Be Reversed

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.
