Postdoc memories (sort of)

"Green Light", 1937, is partially set in the Bitterroot Valley, Montana, deals with tick-borne disease. It includes shots of my old lab home at Rocky Mountain Labs, Hamilton. The lab itself looks almost identical to when I was there, 1994-1998. The film stars Errol Flynn.

Infographic on the chemistry of popcorn. The most significant aroma compounds are 2-acetyl-1-pyrroline (roasty, popcorn-like aroma), (E,E)-2,4-decadienal (fatty, fried aroma) and 2-furfurylthiol (roasted coffee-like aroma). Pyrazines, pyridines and phenols also contribute. Butter-flavoured compounds, including diacetyl, can be added, and can cause respiratory problems for workers in manufacturing facilities. Popcorn pops due to the escape of pressurised water vapour. Molten starch bursts through the shell and rapidly cools, giving popcorn its fluffy appearance

A happy memory from teaching microbiology students. I used to have an exercise where students would plate a dilution series of mixed E. coli expressing different pigments, pick one colony color out, and restreak to purity. A student made a labeling mistake, and turned it into this awesome meme.
