A new Dartmouth study opens new avenues for understanding—and potentially manipulating—how cells decide to live or die.

Bile acids are essential signaling molecules derived from cholesterol metabolism in the liver and are crucial for the digestion and absorption of fats. These molecules undergo further modification in ...

Archaerhodopsin 3 (AR3) is a microbial proton pump that increases alkalinity inside a cell when exposed to green light.

How did cells evolve a process to end their own lives? Recent research suggests that apoptosis, a form of programmed cell death, first arose billions of years ago in bacteria with a primitive ...

When exposed to green light, the protein AR3 increases alkalinity in cells, disrupting cellular functions and causing ...

One of the hallmarks of cancer cells is their ability to evade apoptosis, or programmed cell death, through changes in protein expression. Inducing apoptosis in cancer cells has become a major focus ...

For this article, Jennifer Fisher Wilson interviewed Guido Kroemer, Research Director, Centre National de la Recherche Scientifique, Institut Gustave Roussy in Villejuif, France. Data from the Web of ...

Mitochondria are often referred to as the powerhouses of the cell. Their main function is to generate the energy necessary to power cells. But, there is more to mitochondria than energy production.
