Heart attack in a dish: a 3-D model

In the U.S., someone has a heart attack every 40 seconds, and yet researchers have not had a model that fully mimics what occurs in the human heart after a heart attack.

Genetics

Probing the genes that organize early brain development

When brains begin developing, there are a lot of moving parts—and when mutations happen in early neurodevelopment, it can lead to disorders like macrocephaly and autism. But scientists don't know much about the ways that ...
