Controlling Muscle Repair

By manipulating a protein called Stat3, researchers regenerated muscle in mice. The approach may point the way to treatments for muscle-wasting diseases.

Cells moving in different ways.

New Mechanism of Cell Movement Revealed

Researchers described how a cell’s nucleus can act as a piston to propel it through a 3-D matrix. The findings may help in the design of strategies to regenerate tissue and inhibit metastatic cells.

Expanding Our Understanding of Genomics

By analyzing the genomes of humans, flies, and worms, scientists are gaining insights into complex biological processes that are vital to human biology and disease.

Cells in mouse hearts.

Molecule Protects Against Heart Failure in Mice

Researchers identified a molecule that plays a role in heart failure in mice. The findings may lead to a new therapeutic agent to treat this common condition.

Chikungunya Vaccine Shows Promise

A chikungunya vaccine gave encouraging results in an early-stage clinical trial. A vaccine could prevent outbreaks of the disease, which recently reached the U.S. mainland.

Glutamate receptor

Structural States of a Brain Receptor Revealed

Scientists determined the detailed structural states of the glutamate receptor, which is involved in learning, memory, and several diseases.

Over 100 Genetic Sites Tied to Schizophrenia

Researchers found 108 genetic regions linked to schizophrenia, including 83 previously unrecognized. The findings suggest new avenues for potential treatments.

Inflamed blood vessels

Gene Linked to Rare Inflammatory Disease in Children

Scientists identified a gene that underlies a rare but devastating autoinflammatory condition in children. The study suggests a potential treatment for this and related diseases.

Brain tissue of a CJD patient

Detecting Human Prion Disease

New tests rapidly and accurately diagnose Creutzfeldt-Jakob disease, an incurable and ultimately fatal neurodegenerative disorder. Such tests would have important clinical and research uses.

Preventing Depression From Age-Related Vision Loss

Depression is a common risk for people who’ve lost vision from age-related macular degeneration. A type of therapy called behavior activation can cut this depression risk in half.

Brown fat in neck and upper back region.

Cool Temperature Alters Human Fat and Metabolism

Men exposed to cool temperatures for a month had an increase in brown fat along with changes in metabolism. The finding hints at new approaches to conditions such as obesity and diabetes.

Tumor cells.

Isolated Cancer Cells May Lead to Personalized Treatments

Scientists used a novel microchip-based method to isolate and grow tumor cells circulating in blood. The technique provides an important step toward personalizing cancer therapy.

Drug Improves Birth Rates for Women with Ovary Disorder

The drug letrozole is more effective than standard therapy in increasing live births for women with polycystic ovary syndrome—a leading cause of female infertility.

Gene Changes Identified in Most Common Lung Cancer

Researchers identified DNA alterations that are involved in the development of lung adenocarcinoma. The findings may lead to more targeted therapies to treat this deadly cancer.

Supercooled rat liver.

Preserving Livers for Transplantation

A new technique increased the time that rat livers can remain viable outside the body. If the approach succeeds in humans, it could aid organ transplant efforts.
