31.   He oversaw its laboratory experiments with vaccines and other biological and pharmaceutical drugs, as well as the approval of new products.

32.   In laboratory experiments in which species compete for survival in small glass bottles, subobscura takes a beating, said Gilchrist, usually disappearing entirely.

33.   In laboratory experiments, compounds based on similar cube-shaped molecules have shown some ability to bind to cancer cells and destroy them.

34.   It is as much a laboratory experiment as a haven for daily-fee golfers.

35.   It also suggests strategies for treatments with experimental drugs that can prevent nerve cell death, at least in laboratory experiments.

36.   Jerry Hulm, manager of electrical systems for Boeing, said the voltage inducement tests were basically laboratory experiments that do not reflect normal flying conditions.

37.   Laboratory experiments have shown that animals can be conditioned or trained to stop being afraid by administering a safety signal.

38.   Laboratory experiments found variable rates of safety depending on the intensity of heat and acid levels.

39.   Laboratory experiments show that females are more likely to mate with a drab male if they know a predator is nearby.

40.   Mathematicians are beginning to make important contributions that help model and understand biological systems, he said, but laboratory experiments still need to guide their thinking.
