Gene regulation in our cells—the decision on which proteins are produced for the various processes of the cell—is strictly regulated. It has long been assumed that this regulation deteriorates with ...

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while ...

A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

All cells in the human body—and the motions they enable, from our beating hearts to our wiggling toes—use energy generated by ...

Add Yahoo as a preferred source to see more of our stories on Google. A study on worms led by researchers from Vanderbilt University School of Medicine in the US has uncovered a previously unknown ...

Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission. Cyanobacteria, an ...

Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

Dopamine is a key neurotransmitter known to modulate motivation and reinforcement learning. While the role of dopamine in these reward-related processes is well-established, the cellular and neural ...

To study biological processes, scientists often take snapshots of the molecules in cells, such as proteins and nucleotides, at specific points in time. In spatial biology, they can leverage molecular ...

A molecular geneticist at Montana State University has discovered a cellular process once believed impossible by scientists – the creation of the amino acid cysteine within a living cell when the cell ...
