Who to Treat with Statins

Two studies found that recent cholesterol treatment guidelines are a cost-effective way to prevent cardiovascular disease.

Caenorhabditis elegans

Magnetic Field Sensor Unearthed in Worms

A sensor in nerve cells of tiny worms detects the Earthís magnetic field. The finding suggests that the ability of animals to detect magnetic fields may be more widespread than thought.

Improving Blood Flow in Preterm Infants

A technique called umbilical cord milking increased blood pressure and red blood cell levels in preterm infants delivered by cesarean section.

Hearing Impairment in Hispanic/Latino Adults

Researchers found that nearly 1 in 7 Hispanic/Latino adults in the U.S. has hearing loss. More research will be needed to determine the factors involved and develop interventions.

Protein nanoparticle designed to fight HIV.

HIV Vaccine Progress in Animal Studies

Research teams achieved important steps needed to prompt the immune system to produce antibodies against HIV. The results show important progress toward design of an effective HIV vaccine.

Shorter Antibiotic Course Effective for Abdominal Sepsis

A 4-day course of antibiotics gave similar results to a longer standard course in people with complicated intra-abdominal infections. Shorter courses could have many benefits.

Protein Involved in Diabetic Eye Disease

Researchers identified a protein involved in advanced diabetic retinopathy. The finding may explain why reatments donít help all patients and suggests a new approach.

Lymphatic Vessels Discovered in Central Nervous System

Scientists found lymph vessels in mouse brains that carry fluid and immune cells from cerebrospinal fluid. Problems in this system might play a role in neurological disorders.

Gene Therapy for Eye Disease Shows Benefits and Limitations

An experimental therapy for an inherited disorder that causes blindness improves vision, but the improvement declines with time. The findings offer insights for future therapies.

Landscape of Gene Expression in the Human Body

A new resource allows scientists to examine how genomic differences affect gene activity in tissues and organs across the body—and how that activity influences susceptibility to diseases such as cancer, heart disease, and diabetes.

Neurons firing.

Controlling Brain Circuits in Mice

Researchers developed a tool that can turn specific sets of neurons on and off in mice to affect behavior. The technology can help scientists study mental health and disorders.
