Baldwin began the ceremonies, welcoming the guests and congratulating the graduates. Gerald O'Connor, PhD, hoods CECS graduate Karen Homa as Gilbert Welch, MD, looks on. Ninety percent of those who participated in the National Resident Match Program secured one of their top three residency assignment choices. Graduates James Feeney and Travis Matheney, bagpipers, open ceremonies. D artmouth Medical School geneticists have clarified the picture of the way living things maintain robust and stable internal clocks to safeguard the timing of daily activities.
Internal clocks are ubiquitous.
In humans they cue circadian rhythms, the 24-hour cycle that paces life's ebb and flow, from when we wake up to when we go to sleep. They are linked to jet lag, seasonal affective disorder and sleep disturbances. Research published in the July 7 issue of Science delineates the dual roles and interlocking connections of the molecular gears that drive biological clocks and prevent them from winding down. The striking parallels in a relatively simple model offer clues to what makes creatures tick, report the DMS authors - Jay Dunlap, professor and chair of genetics, Jennifer Loros, professor of biochemistry, and Kwangwon Lee, a postdoctoral fellow. Studying the development of spores in the bread mold Neurospora, Dunlap and Loros have teased apart the genetic cogs that form the basis of most living clocks.
