Researchers at the Keck School of Medicine of the University of Southern California (USC) have explained how certain key mutations occur in human lymphomas—a process that has, until now, remained a mystery.
The findings of the study will have a significant impact on future study of how human lymphoma occurs.
Chromosomal translocations, in which segments of DNA [...]

A fruit fly`s immune system can tell time, researchers at the Stanford University School of Medicine have found, and how hard it punches back against infections depends on whether the fly is snoozing or cruising. The discovery could have implications for human health, too.
Working with jerry-rigged, light-bulb-laden shoeboxes to manipulate the flies` daily cycle and [...]
