Clues in H7N9 Influenza Genetic Sequences

Researchers quickly analyzed the novel avian influenza virus that’s caused recent illness and death in China. Their effort gives clues to the virus’s origin, transmissibility and treatment.

Lab-Grown Kidneys Function in Rats

Scientists created artificial kidneys that can filter blood and produce urine in rats. The approach may one day help patients who need organ transplants.

ß-arrestin-1 binds a G-protein coupled receptor.

Arrestin Developments

Researchers visualized a key step in how signals from outside the cell are muted within. The finding gives insight into the complex systems that control our cells.

Red Meat-Heart Disease Link Involves Gut Microbes

The link between red meat consumption and heart disease, a study suggests, may stem from gut microbes breaking down carnitine, a compound found in red meat.

Cholesterol as Target for Age-Related Vision Loss

Research in mice suggests that targeting cholesterol metabolism in the eye may help prevent progression of a severe form of age-related macular degeneration.

Seeing Into the Brain

Scientists developed a technique to preserve the brain’s 3-D structure down to the molecular level, allowing for study of the brain’s inner workings at a scale never before possible.

Gut Microbes Affect Weight After Gastric Bypass

A study in mice suggests that gastric bypass surgery may result in weight loss in part by altering microbes in the gut.

Research Hints at New Approach to Addiction

Stimulating a specific part of the brain reduced compulsive cocaine seeking in rats. The finding suggests a potential approach to change addictive behavior.

Weight Loss in People with Serious Mental Illness

A new study showed that a weight-loss intervention can help overweight and obese people with serious mental illnesses—such as schizophrenia, bipolar disorder and major depression—lose significant weight and keep it off.

Chelation Therapy May Help Reduce Cardiovascular Events

Chelation therapy—an unproven alternative treatment for heart disease—modestly reduced cardiovascular events in adults who’d suffered a prior heart attack. The findings weren’t conclusive but will help guide future research.

Technique Directs Immune Cells to Target Leukemia

A type of targeted immunotherapy induced remission in adults with an aggressive form of leukemia that had relapsed in 5 patients. The early results of this ongoing trial show the potential of the approach.
