In a photograph accompanying a September 10 MIT Tech Talk story headlined "Gene with role in yeast life span discovered," two of the researchers were misidentified. The corrected caption appears below:
Graduate student Kevin Mills (left), Professor Leonard Guarente (center) and postdoctoral fellow David A. Sinclair survey an autoradiogram of DNA from yeast cells.
An item in the Awards and Honors section of the same issue, concerning an award from the Health Physics Society to Dr. Constantine Maletskos, incorrectly listed Frank Massï¿½ï¿½ï¿½ as the former director of the Radiation Protection Office. He currently holds that position.
A version of this article appeared in MIT Tech Talk on September 17, 1997.
