Cas9 – The Good, The Bad, and The Ugly of a Viral Hunter

The CRISPR/Cas9 system for viral defense in bacteria is a recently discovered system that is really fascinating.  Cas9 is useful for genome engineering and currently getting a lot of attention in this area.

Greene Lab Studios (a subsidiary of the Greene Lab) put together this video to the title music from the soundtrack of the film  The Good, The Bad, and The Ugly composed by Ennio Morricone.  The video briefly explains how the CRISPR/Cas9 system works in recognizing and cleaving foreign nucleotides in a cell.

Fungi: The Rotten World About Us

Here’s another video I like to show students and I find it quite entertaining — although from 1980 it’s a little dated.  This version was recorded from VHS, so the image quality isn’t so great.  This video was put together by wildlife producer Barry Paine working with the BBC for its renowned “The World About Us” series and made it’s way to the US and appeared on the PBS show Nature in the early 80’s.

Just What Is A “Gleba”?

I’m in the process of organizing some of my old teaching materials and I have a few VHS tapes of clips of mycologically related videos for teaching about fungi. Since I don’t have a working VHS tape recorder — and don’t expect many departments to maintain one either — I’ve been trying to find some of the videos online. Here’s a short video clip that I usually show when teaching about the Gastromycetes. The students always remember what a gleba is for their exam.
