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.

Bram Servais formerly worked for Cortical Labs but holds no shared patents or stock and has severed all financial ties. As prominent artificial intelligence (AI) researchers eye limits to the current ...

After cells die, they leave a residue that sends messages to other cells in ways that are valuable to the immune system. But this process can also be hijacked by viruses such as influenza, according ...

A new study shows, for the first time, that cow cells can naturally become immortal—continuing to divide indefinitely without genetic modification or any abnormal transformation. This overturns ...

When cancer cells are physically squeezed, they mount an instant, high-energy defense by rushing mitochondria to the cell nucleus, unleashing a surge of ATP that fuels DNA repair and survival. This ...

In a proof-of-concept experiment, scientists demonstrated that you can create and fertilize human eggs in the lab using sperm, genes from skin cells, and the "shells" of existing egg cells. When you ...

Scientists have created human eggs containing genes from adult skin cells, a step that someday could help women who are infertile or gay couples have babies with their own genes but would also raise ...

Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The ...

Cancer cells can brainwash their neighbors. Like the CIA deploying secret agents to turn an enemy, tumors use a similar strategy to manipulate nearby cells. The tumors’ agents are mitochondria, the ...

UC Davis researchers Gant Luxton, Daniel Starr and Xiangyi Ding have used tiny fluorescent particles to study what is going on inside the cells of Caenorhabditis worms. They found that the cells are ...
