Scientists are uncovering a surprising truth about aging cells: some may damage the body, while others help protect it. The discovery is fueling a new wave of precision anti-aging therapies aimed at ...

Every pregnancy depends on an organ that most people will never see. As organs go, the placenta — the tissue that surrounds a developing fetus — is a jack of all trades. It can filter toxins like a ...

Organisms are composed of cells, some of which are constantly replaced, while others stay in place for a long time. For many years, scientists studied cell biology and tissue function by analyzing the ...

The body's cells change their shape to close gaps such as wounds—with part of the cell flexing depending on the curve of the gap and the organization of cell-internal structures, a new study reveals.

Scientists from Tufts and Harvard created microscopic robots from human cells. They say the "biobots" can self-assemble and have a remarkable healing effect on other cells. Researchers hope the ...

Imagine tiny fists punching their way through your body. For some cancer patients, this may be the reality. Melanoma cells can mechanically tunnel their way through tissue using fleshy membrane ...

Editing a small number of blood-forming stem cells to encode powerful antibodies turns the immune system into a living drug ...

Red blood cells carry oxygen from the lungs around the body. They then carry carbon dioxide from around the body back to the lungs. These cells are an important component of blood. However, a range of ...
