Hmm that's not an easy question to answer since enzymes are not sold pure, they are sold suspended in a storage buffer and the quantity is measured in Units (for example for EcoRI, one of the most common restriction enzymes, New England Biolabs defines 1 U as the amount required to digest 1 microgram of Lambda DNA in 1 hour at 37 degrees in a 50 microliter reaction). I guess you could figure out the weight per U, but that's way to much effort and I'm not sure I could even find all the constants I'd need. If we just approximate that 1 mL of resuspended enzyme is 1 g, 1 kg of enzyme+storage buffer (at 20 000 U/mL, which is about the standard stock concentration you'd usually buy) is 91 600 $ at catalog price. For a more expensive enzyme like NotI the same approximation yields 1 128 000 $/kg Similarly 1 kg of Phusion DNA polymerase in its storage buffer (also from NEB) is approximately 1 695 000 $. All those prices are based on buying the largest volume offered on their site (since those usually save you about 20%) but not taking into account the preferential prizes labs usually negotiate.

Wow, that was way more effort than I was expecting. My 'joke' was that restriction enzymes are worth way, way more than their weight in gold (which is currently around $ 42500 per kg ). Luckily you don't need large volumes of restriction enzymes for experiments.

When you actually start thinking about the value of the things you handle it gets a bit daunting sometimes.

The premodern era is also commonly known among academics as the era of God just constantly loving our poo poo up with lightning bolts. So is a post-ironic meme the part of a meme lifecycle when a meme becomes part of common parlance but loses all original meaning? Like how your local little league team will make team shirts that say "Keep Calm and Fighting Ladybugs Rule!" or some such for some inscrutable reason.

First of all, I would assume they mean the dictionary definition of a meme, not the 'internet meme' meaning. Then I still don't understand anything in that picture, but it sounds slightly less stupid.

Rockets carrying humans will result in fatalities 99.99% of crashes. F1 cars carrying humans will result in fatalities in maybe (total guess) 1% of crashes. One of these is a more dangerous crash than the other, and it has nothing to do with total number of occurrences or most recent crash.

True but rockets that aren't the space shuttle have a launch escape system that carries the capsule full of humans far away from the exploding rocket.

I also love the one that visualizes different amounts of money--like rappers' net worth, nations' GDP, etc--as big boxes. Not gonna post it because this thread is for bad/funny, not just miscellaneous interesting. Maybe someone should make a thread like that, preferably one less insufferable than the D&D picture thread. Anyway, xkcd isn't high art, and I think Munroe knows it. I've never really encountered anybody who puts him on a pedestal or anything, but I see lots on this site who hate him. It's like how much easier it is to find people making fun of tumbler than the batshit transethnic otherkin nonsense they make fun of.

The space shuttle had that too. Well, technically it was a jettison for the rockets/fuel tank, then the orbiter would glide away. But the incident happened too fast for that.

Not really. The solid rocket boosters couldn't be shut down and would destroy the shuttle (or the parachutes of a hypothetical escape capsule) with rocket exhaust had they been jettisoned while firing. So while it's true that there was an abort procedure, it couldn't be used until the SRBs were finished burning. Contrast this with a capsule design which Nasa requires to be capable of performing an abort anytime from "sitting on the pad" to "we're in space".
