I made a bad mistake on a great podcast Friday night. I accused Andrew Scott and a gaggle of other Younger Dryas Impact critics of sub-par work in their 2010 paper investigating carbon spherules, they DID use Transmission Electron Microscopes, and I flat out said they used only Optical Microscopes. Thankfully, since I brought the paper up in the show, I went back to the paper and discovered this false accusation myself in time to apologize.
I am sorry for the mistake, Scott et al. This has been a long debate and even the flawless memory of the Tusk can be tested.
