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 ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants. A study by UT ...

A bandage usually covers a wound. This one comes with a bonus: it gives repair instructions. Researchers at Rice University ...

R3 Bio wants to grow human bodies without brains, which could replace lab animals in drug research and one day supply organs ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

The potential for these kinds of machines to reshape computer processing, increase energy efficiency, and revolutionize medical testing has scientists excited. But when do we consider these cells to ...

Blood cells carry a deep evolutionary history. A new analysis suggests their earliest ancestors were macrophage-like cells inherited from single-celled life.

Almost all animal species—including humans—have blood cells, but between different species our blood tells different stories. The lineage and components of blood cells vary widely, and this variety is ...
