Clues to Congenital Heart Disease

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.

Green bacteria in an infected mosquito’s midgut.

Infection Makes Mosquitoes Immune to Malaria Parasites

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.

3-D Printing of Working Bionic Ears

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.

Gene Linked to Migraine and Sleep Disorder

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.

Mouse liver that overexpresses betatrophin.

Hormone May Help Treat Diabetes

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.

Genomic Analysis of Endometrial Tumors

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.

Microscopic Star-Shaped Grippers Take Biopsies

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.

Killing Cancer With Radioactive Bacteria

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.
