Miniature organs have a new lifeline. Mimicking the way early human embryos grow blood vessels, scientists nudged multiple types of mini organs to sprout their own vascular networks. Also called ...

In an exciting scientific breakthrough, researchers at Johns Hopkins University have grown a miniature human brain in the lab. This tiny brain is called a multi-region brain organoid (MRBO). It mimics ...

Though an estimated 60 million people around the world have atrial fibrillation, or A-fib, a type of irregular and often fast heartbeat, it's been at least 30 years since any new treatments have been ...

Brain organoids have come a long way. These mini-brains, at most the size of a pea, are made from stem cells or reprogrammed skin cells and churned inside a bioreactor full of nutrients. With ...

Human mini-lungs grown by University of Manchester scientists can mimic the response of animals when exposed to certain nanomaterials. The study is published in Nano Today. Though not expected to ...

Your gut has an obvious job: It processes the food you eat. But it has another important function: It protects you from the bacteria, viruses, or allergens you ingest along with that food. “The ...

How did your heart form? What triggered your first heartbeat? To this day, the mechanisms of human heart development remain elusive. Researchers know the heart is the first organ to fully function in ...
