In Brief
Who: Elizabeth H. Blackburn
Line of work: A cell and molecular biologist, Blackburn researches the structure and functioning of the DNA that caps the ends of chromosomes.
Where: University of California, San Francisco
Big Picture: Blackburn has extended her Nobel Prize?winning work on telomeres to develop measures that aim to assess overall risks for heart disease, cancer and other chronic illnesses.
A molecular timepiece that resides inside each cell still makes headlines, decades after Elizabeth H. Blackburn conducted pioneering studies into how it works. The most recent experiments by Blackburn and other researchers have demonstrated that these cellular clocks, known as telomeres, may act as barometers of whether a person will remain healthy or not.
