This week on TechKnow: Join our expert “TechKnow" contributors Phil Torres, Kyle Hill, Rachelle Oldmixon and Marita Davison as they explore scientific innovations and their impact on our lives. Kyle meets two Harvard researchers who believe they have isolated a protein that could one day save countless lives by making an old heart young again. Rachelle heads to Montana, where scientists are working to save the state’s rivers and the fly fisherman’s holy grail, the cutthroat trout. Plus Marita goes inside San Francisco’s new Bay Bridge to see its innovative approach to earthquake proofing.
