Went for a seminar today about circadian rhythms in bacteria. They wanted to mutate every single gene in the bacteria to see the effects on the rhythm. Every single gene. That's 2700. You know how much cloning that is? And I can't even do a single cloning right. And the speaker flashed a whole long list of undergrads who helped them clone, it was a pretty long list. Bacteria people are fun. They draw all kinds of things with bacteria on plates. So this group drew a sun in one plate and a moon in another and fixed a promoter that is under circadian control to a fluorescent protein. And the sun lit up for 12h and the moon lit up for 12h. How cool!
