Vibrations influence the circadian clock of a fruit fly

The internal circadian clock of a Drosophila (fruit fly) can be synchronised using vibrations, according to research published today in the journal Science. The study suggests that an animal’s own movements can influence its clock.

The circadian clock, which underlies the daily rhythms characterising most of our bodily functions, including the sleep cycle, is mainly set by diurnal changes in light and temperature. (more…)

International team of scientists finds adaptations to stress in oyster genome

When it comes to stress, oysters know how to deal. The tough-shelled mollusks can survive temperature fluctuations, toxic metals and exposure to air, and a new study of their genetic makeup is helping to explain how.

An international team of scientists, including the University of Delaware’s Patrick M. Gaffney, professor of marine biosciences, sequenced the genome of the Pacific oyster, Crassostrea gigas, in a Nature paper published on Sept. 19. (more…)
