A resurrected ancient enzyme is helping scientists test how reliably Earth’s oldest rocks record signs of life.

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

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, ...

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 ...

Scientists discovered hundreds of energy-making enzymes secretly working on human DNA—revealing a hidden “mini-metabolism” ...

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 ...

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 ...

More than 200 metabolic enzymes, many of which are normally tasked with producing energy in the mitochondria, are also found ...

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 ...
