It can be hard to keep track of the truth. So this week, Innovation Hub is all about accountability. We cast a critical eye on questionable science, learn how the internet is archived, and hear from the man who brought Congress to your living room TV.

First up, scientists thought they had found “God’s own medicine.” It was plant-based, very effective, and didn’t hurt your stomach like aspirin. But this over-the-counter drug, called Heroin, turned out to be highly addictive. Paul Offit tells us stories of when science goes wrong — and what we should do the next time we see a “miracle cure” or extraordinary claim.

Then, do we need libraries when everything is on the internet? Brewster Kahle says yes — and that we even need a library for the internet. The founder of the Internet Archive notes that things can go missing (or get changed) on the web, and it’s his mission to make sure that every version of every web page is cataloged online.

If a C-SPAN segment airs but no one is around to hear it, does it really make a sound? We talk with founder Brian Lamb about his no-commercials, no-stars cable network - which never worries about the ratings - and learn the secrets to his success. Even if it doesn’t quite get the same ratings as Sunday Night Football, C-SPAN isn’t going away anytime soon.
