In a world-first, scientists at Tel Aviv University have successfully 3D printed a tiny human heart using real human cells. This innovation could reshape the future of organ transplants, offering a ...

Ordinary human cells, not just neurons, respond more strongly to memory signals when they arrive in spaced bursts rather than ...

Even after decades of research, biologists are still uncovering surprises about the human body. A team of researchers from the University of Virginia and the National Institutes of Health (NIH) have ...

A new organelle has been discovered in human cells — and scientists call it a "hemifusome." Like the full-size organs in our bodies, the organelles within cells are specialized structures that carry ...

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 ...

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 ...

Contemporary artificial intelligence (AI) systems, such as the models underpinning the functioning of ChatGPT, image ...

The body’s “killer” T cells don’t just attack—they strike with astonishing precision, forming a tiny, highly organized ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

AI could "give the scientific community a way to address the most difficult and urgent questions in human health," argues ...

A University of California, Riverside study reports that cells in the earliest stages of human development could be ...
