Rob, everyone loves a deal and a bargain from time to time, don't they? Absolutely, mate. And you know where you can grab a great deal? Talk to me. Where? The eBay app. Yes, you are correct. You didn't need to talk to me. I already knew it. I love eBay. When you're buying, you can discover loads of hidden gems. there's so many items where you think I would have never found that anywhere else.

Then when you're buying, you can discover loads of hidden gems. There's so many items where you think I would have never found that anywhere else. Then when you're selling, it's so simple and most

importantly, free. It's free, Rob. When it's this easy to sell for free and there's great deals

on things you love. You can't help but say when it's eBay. It excludes vehicles and business

sellers.

Welcome to Science Talk, the weekly podcast of Scientific American posted on November 3rd, 2010.

I'm Steve Murski. London, 1953.

Scientists are on the verge of discovering what they call the secret of life, the DNA double helix.

Providing the key is driven young physicist Rosalind Franklin.

But if the double helix was the breakthrough of the 20th century, then what kept Franklin out of the history books?

A play about ambition, isolation, and the race for greatness.

That's on the program for a panel discussion about the new play Photograph 51 by Anna Ziegler,

I recorded the panel discussion, and you'll hear part one of that in a moment. I just want to give you a little more background. The production is an effort of the Ensemble Studio Theater and the

Alfred P. Sloan Foundation. You may hear some reference to E.S.T. Sloan, and that's what they're talking

about during the panel. Now, photograph 51 refers to a very important x-ray diffraction

image that was key to the elucidation of the double helical structure. You're going to hear

references to some individuals. In addition to Watson and Crick and Rosalind Franklin, there's

Maurice Wilkins, as well as Ray Gosling,

who was an assistant, a postdoc. You'll also hear reference to John Randall. Randall was the
