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 ...

The biological cycle of our existence seems relatively straightforward: we’re born, we live, we die. The end. But when you examine existence at the cellular level, things get a bit more interesting.

Cells are not immortal, and that is a good thing. After a certain number of divisions, many human cells stop multiplying for ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

Spaceflight makes certain human stem cells age faster, a new study has found, furthering scientists’ understanding of the potential effects of space exploration on the human body. Stem cells are found ...

Microtubules perform an active role in communication within the cell by transmitting received signals to the cell's ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life. Each of us starts ...

Biologists have long suspected that aging is not just a slow, inevitable fraying of our cells but a process governed by ...

Aging is the process of getting older. In biology, aging refers to how, over time, the cells in our bodies wear out or get damaged. They no longer work as well as they used to. Some visible signs of ...

When two cells "talk" to each other, they often do so through tiny channels called electrical synapses. Unlike chemical ...

Electrically stimulating key cells in the immune system could "reprogram" them to reduce inflammation and encourage faster and more effective healing in the body. This is the discovery of scientists ...

The latest chemistry news, including important research advances, business and policy trends, chemical safety practices, career guidance, and more. Current approved CAR T-cell therapy treatments rely ...
