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 ...

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 ...

Organovo’s 3D-printed mini-liver just shattered its own record, carrying out the same cellular functions as a natural human liver for 40 days in the lab. That may not seem like a lot — human liver ...

It’s not often that a twitching, snowman-shaped blob of 3D human tissue makes someone’s day. But when Dr. Sergiu Pasca at Stanford University witnessed the tiny movement, he knew his lab had achieved ...
