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 ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

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 ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. In a world first that challenges what we thought we knew about biology, scientists have successfully engineered animal ...

Scientists transplant photosynthetic nanoparticles into rats and rabbits with degenerative diseases to boost energy, restore ...

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions of this cell type have hardly been studied to date. Researchers have now determined that ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

CD8+ T cells divide cysteine between pathways that control growth and cancer-killing activity. Adjusting its use can enhance ...
