Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining ...

In cell culture experiments, stem cells from human baby teeth promoted neural cell proliferation. In rat models, the stem ...

More than a billion years ago a hungry cell devoured a tiny blue-green alga. But instead of the former simply digesting the latter, the duo struck a remarkable evolutionary deal. Now scientists are ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...
