Jennifer Puck, M.D., an expert on human primary immunodeficiencies at the University of California, San Francisco, will deliver the next Flexner Discovery Lecture on Thursday, Dec. 12.

The director of the National Cancer Institute, Harold Varmus, M.D., will deliver the next Flexner Discovery Lecture on Thursday, Nov. 21. His lecture, “New Directions in Cancer Research,” will begin at 4 p.m. in 208 Light Hall.

Michael Klein, Ph.D., dean of the College of Science and Technology at Temple University, discusses his use of computer simulation to explore ion channels and other complex molecular structures in the cell, during his Flexner Discovery Lecture last week.

Intracellular receptor expert Keith Yamamoto, Ph.D., of the University of California, San Francisco, discusses molecular signal processing during his recent Flexner Discovery Lecture.

The occasional failings of science tend to draw big headlines — findings that can’t be replicated or increasing numbers of papers that are retracted because studies were improperly or even fraudulently conducted.

Keith Yamamoto, Ph.D., an international leader in the study of signaling and gene regulation by intracellular receptors, will deliver the next Flexner Discovery Lecture on Thursday, Oct. 10.

We’re on a potential collision course, said last week’s Flexner Discovery Lecturer, between the delivery of good medical care and the possibilities offered by genome medicine.
