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…)

*The U’s active learning biology courses garner attention*

What if you could remove lead from a person’s blood with a bacterial protein that snags the toxic metal?

Or treat spinal cord injury by shutting off a gene that prevents nerve regrowth?

Ideas like these used to be the exclusive province of practicing biologists. But they are among 14 ideas conceived and presented recently by students in the University of Minnesota’s introductory biology course. (more…)
