Corticosterone interferes with signaling in the skin that normally activates hair follicle stem cells, possibly explaining the link between stress and hair loss.

The Sloan Kettering researcher used mutagenic screening to probe genes and molecular pathways, including Toll and Hedgehog, essential to development in fruit flies and mice.

Arnold Levine will discuss his discovery of p53 and the evolution of the field since then, and Jon Chen will discuss the use of single-cell phosphoproteomics in identifying changes in key signaling networks, including p53.

Defects in the response to fire-generated karrikins turn out to be responsible for root anomalies that were previously ascribed to other plant hormones.

The plant geneticist has revolutionized researchers’ understanding of how light affects plant growth and development, and is engineering plants to combat climate change.

To see if the spiky fish shares signaling pathways found in other organisms, scientists scooped up specimens during a mating frenzy on the shores of Japan.

Transmission of stress signals in E. coli is dependent on the distance between its inner and outer membranes.

And the same endocannabinoid system that translates marijuana's buzz-inducing compounds into a high plays crucial roles in health and disease outside the brain.

The system responsible for the buzz humans get from marijuana plays a passel of physiological roles outside the brain.

Charles Sawyers, who began his research career just as the genetic details of human oncogenes were emerging, codeveloped Gleevec, the quintessential targeted cancer therapy.
