PITTSBURGH (AP) — One of America’s corporate giants is investing billions of dollars in the new boom of oil and gas drilling, or fracking. General Electric Co. is opening a new laboratory in Oklahoma, buying up related companies and placing a big bet that cutting-edge science will improve profits for clients and reduce the environmental and health effects of the boom.

Environmentalist Michael Shellenberger calls it a “positive response to legitimate public concerns” about the impacts of the fracking boom.
