“It immediately looked right.”
It’s been 60 years since the double helix structure of DNA, the key to life itself, was first revealed to the world. The BBC’s “Science in Action” walks the listener along the journey of this discovery with some of the scientific giants of the time. The delight is still there in those voices. So wonderful.
Also clears up some of the debate over the credit of Crick and Watson. Their approaches to modeling and sense of beauty moved the idea forward… through actual base pairing cut-outs!

Rapping the LHC
Marc Sanchez, Associate Producer
I was recently doing some research on Nobel Prize-winning theoretical physicist Frank Wilczeck. Truth be told, I can barely spell “physics” much less grasp the concepts he works with, like quantum chromodynamics (QCD).
Currently, Mr. Wilczeck is trying to combine the theories of how to measure the four forces of nature — gravity, electromagnetism, strong force, and weak force — into one, unified theory. To help solve this problem, he has enlisted the help of the Large Hadron Collider (LHC). That’s the gigantic particle accelerator that got people in a tizzy about sucking the Earth into a self-made black hole.
Physicists, including Mr. Wilczeck, have assured us that our universe is safe, but I still needed to wrap my head around the LHC. Enter Kate MacAlpine, an employee who works with the particle accelerator in Switzerland. She put together a rap that actually does a really good job of breaking down the science.
