For more than a century, the story of the brain has been told as a tale of neurons, with every thought and memory traced to their electrical chatter. That narrative is now being rewritten as evidence ...

A study led by Brazilian researchers has reconstructed the brain environment in the lab, revealing for the first time live interactions between cancer and healthy tissue, with the potential to reshape ...

As prominent artificial intelligence (AI) researchers eye limits to the current phase of the technology, a different approach is gaining attention: using living human brain cells as computational ...

Scientists at Johns Hopkins have grown a first-of-its-kind organoid mimicking an entire human brain, complete with rudimentary blood vessels and neural activity. This new "multi-region brain organoid" ...

Millions of people live with atrial fibrillation, a racing, uneven heartbeat that can leave you exhausted and scared. Yet it has been at least 30 years since a new drug for this common rhythm problem ...

Metastasis occurs when cancer cells break away from the original tumor and travel through the bloodstream to form new tumors in other parts of the body. It is the leading cause of cancer-related death ...

A confocal microscopy image of a nine-day-old human embryo, with specific proteins and cellular structures colored distinctively. Green relates to embryonic stem cells and magenta associates with ...

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 ...

Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...
