Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and ...

The very cells that created us may have a role in saving our lives. Scientists have always been amazed by the energy production system in a sperm’s tail. The system drives flagellar movement and is ...

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 ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

Nicotiana benthamiana plants in a lab at UC Davis. Plants form new branches when a hormone called strigolactone breaks down. UC Davis plant biologists have now defined the enzymes that break down ...

A UCSF team finds a liver protein, released with exercise, that improves memory in aging and Alzheimer’s disease by repairing the brain’s blood vessels. It's the missing link between exercise and ...

Scientists uncover a pivotal enzyme, XccOpgD, and its critical role in synthesizing C G16, a key compound used by Xanthomonas pathogens to enhance their virulence against plants. This breakthrough ...

For much of nutrition science history, trace minerals were discussed almost exclusively in the context of deficiency diseases ...

A new study shows exercise releases a liver enzyme that repairs aging brain blood vessels and restores memory in mice.

Every year, thousands of tons of brown algae are extracted from the seabed to obtain compounds such as alginates, a polymer composed of sugars that has high density and strength, offering potential ...
