Scientists slow aging by engineering longevity in cells

Human lifespan is related to the aging of our individual cells. Three years ago a group of University of California San Diego researchers deciphered essential mechanisms behind the aging process. After identifying two distinct ...

How the humble protist could shore up the world's food supply

Protists, a broad class of generally single-celled organisms that includes algae and amoebae, have long been regarded as a "catch-all" category for diverse microorganisms. Because of their diversity and prevalence, protists ...

Researchers shed new light on the motor of DNA replication

DNA replication is the process whereby cells make an exact copy of their DNA before cell division. A key part of the intricate DNA replication machinery is a molecular motor called CMG, which has the vital task of separating ...

Study reveals new mechanism for DNA folding

A hitherto unknown mechanism for DNA folding is described in a study in Nature published by researchers from Karolinska Institutet and the Max Planck Institute for Biophysics. Their findings provide new insights into chromosomal ...
