A large-scale genomic analysis found that non-inherited mutations in hundreds of genes together account for about 1 in 10 cases of severe congenital heart defects, the most common type of birth defect.
Researchers established a bacterial infection in mosquitoes that helps fight the parasites that cause malaria. These infected insects could be a significant tool for malaria control.
Researchers used 3-D printing to create functional bionic ears that receive radio signals. Using similar techniques, it may one day be possible to create bionic implants and prostheses.

New findings may help improve nutritional supplements for treating age-related macular degeneration, the leading cause of blindness nationwide.
Researchers linked an abnormal gene to both a common type of migraine and a rare sleep disorder. The discovery provides a new avenue for exploring treatment options.
A hormone called betatrophin prompts cells in the pancreas to multiply and produce more insulin. The finding, in mice, may lead to new ways to combat diabetes.

A new study suggests that genomic classification of endometrial tumors could help guide treatment strategies. The analysis also revealed novel subtypes and found similarities to other cancers.
Researchers designed star-shaped microtools that close in response to body heat to grasp tissue samples. The microgrippers could be used to retrieve tissue samples in many hard-to-reach places.
Live bacteria delivered a lethal radioactive payload to pancreatic cancer cells in mice. With further development, the approach might one day help doctors fight this deadly type of cancer in people.

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

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

A study in mice suggests that gastric bypass surgery may result in weight loss in part by altering microbes in the gut.
Stimulating a specific part of the brain reduced compulsive cocaine seeking in rats. The finding suggests a potential approach to change addictive behavior.
Researchers discovered that distinct sets of neurons respond to heat and cold. The findings provide an elegant explanation for how mammals sense temperature.
