On Sept. 7, federal scientists reported that despite the massive release of oil from the damaged BP well in the Gulf of Mexico, no such dead zone developed.

An engineer teaches her colleagues to share their toys
In her synthetic biology lab at Stanford, Christina Smolke designs circuits and switches using biological components, work that may lead to yeast that crank out medicines or ways to reprogram the immune system. Winner of the 2009 World Technology Award in biotechnology for doing work of “the greatest likely long-term significance” in her field, Smolke […]

‘Bug traps’ in Gulf to use BP oil as bait
To assay how appetizing polluting oil is to native Gulf micobes — and how rapidly they degrade it — researchers plan to set 150 “bug traps” on August 26.. Their bait: the same oil that had been spewed for months by BP’s damaged Deepwater Horizon well.
