Scientists in Japan have created hybrid plant-animal cells, essentially making animal cells that can gain energy from sunlight like plants. The breakthrough could have major benefits for growing ...

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 ...

Chloroplasts, the parts of cells that allow plants and algae to photosynthesize, are thought to have originated more than 1 billion years ago, when photosynthetic cyanobacteria lived symbiotically ...

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 ...

Critical proteins involved in animal stem cell regulation are much older than previously thought, predating the origin of animals that likely evolved more than 700 million years ago. This is the ...

This fluorescence image shows chloroplasts (magenta colored) successfully incorporated into the hamster cells, with other features of the animal cell also highlighted (nuclei in light blue and ...

Senescent cells, which emerge after tissue injury, create an aged-like inflamed microenvironment that is negative for stem cell function and tissue repair. The finding provides a basis for mitigating ...

Scientists hoping to discover better ways to boost immune function — which could lengthen our healthspan and protect immunocompromised patients — may have a new target, according to findings published ...
