Tody I Learned: 1) If you leave ice shavings at -20 °C for a couple of hours, the shavings will fuse into a more or less solid mass. Not recommended (unless you need a big hunk of porous ice for some reason. Hmm....) 2) ...another recommended food for fruit flies in culture -- cheese. Why am I not surprised? 3) The correlation coefficient between RNA expression and protein levels, across a bunch of different tissues, is around 0.35-0.5. That's... way lower than I expected. Makes me wonder just how useful RNA-seq really is (I mean, not really, it's still bloody useful, but still -- half of variance unexplained by RNA levels? That's more than I would have guessed).
