Study sheds light on genetic 'clock' in embryonic cells

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating ...

New chemistry technique reproduces nature's elusive complexity

(Phys.org)—Scientists at The Scripps Research Institute have shown how to synthesize in the laboratory an important set of natural compounds known as terpenes. The largest class of chemicals made by living organisms, terpenes ...

Scientists tie DNA repair to key cell signaling network

University of Texas Medical Branch at Galveston researchers have found a surprising connection between a key DNA-repair process and a cellular signaling network linked to aging, heart disease, cancer and other chronic conditions. ...

We need to talk: How cells communicate to activate notch

During formation of multi-cellular organisms, cells need to talk to each other to make critical decisions as to what kind of cell to become, as well as when and where to become that cell type. The Notch signaling system allows ...

Study uncovers key mechanisms of cell communication

(PhysOrg.com) -- A unique bridging process may be behind a mystery of intracellular communication, according to new Cornell research published Feb. 4 in the journal Cell.

Biologists identify a new clue into cellular aging

The ability to combat some age-related diseases, such as cancer and diabetes, may rest with scientists unlocking clues about the molecular and cellular processes governing aging. The underlying theory is that if the healthy ...

Researchers find cells move in mysterious ways (w/ Video)

Our cells are more like us than we may think. They're sensitive to their environment, poking and prodding deliberately at their surroundings with hand-like feelers and chemical signals as they decide whether and where to ...
