HEY EVERYONE LOOK AT THESE NEKO ATSUME UNDERTALE CHARACTERS MY FRIEND DREW!!!!! AHHHHHH!!!!!!!! She Doesn’t

Wind tunnel testing plays a major role in the planning of many space missions. Here a model of the Mars Sample Return Orbiter is tested at Mach 10 to determine the heat shield’s response to aerobraking off Mars’ atmosphere. The colors are the result of electron beam fluorescence, in which an electron gun is used to ionize molecules in the flow, which causes them to emit photons (light). The technique can be used for flow visualization–as in the case of the shock waves shown here–or to measure flow characteristics like density, temperature, and velocity.

fun things to do in lab

accidentally crushing a pcr tube when opening it with one hand

dropping… anything. especially an entire box of frozen samples. 

slightly too large gloves and getting them caught as you close tubes

when the magnetic spin bar spins too fast and does the thing

listening to someone else’s forgotten timer go off

“uh… what’s that smell..”

going in for a pipette tip and then overturning the entire box

16 hour time-points

srsly who invented 16 hr time-points

they’re inhumane

labelling rows and rows of 600 ul microcentrifuge tubes by hand

“we’re sorry but this reagent has been back-ordered for 3 months”

listening to the scraping noise of plastic culture flasks on metal shelves

getting your samples stuck in any sort of machine

“i need you to go and catalog every chemical we have”

cleaning cell culture incubators with aerosolized 70% ethanol 

having the fire alarms go off when you’re literally in the middle of something that can not be put down no i will perish in this fire before i forgo this damn experiment!

that sense of pure panic when you realize you miscalculated how much reagent you need

“one of your mice died and its cage mates ate half the body”

PUMPKIN-SPICED FLUORESCENCE

Inside a pumpkin, seeds don’t need much chlorophyll—the molecule that helps plants convert light into food—because there isn’t a lot of light deep inside the fruit’s flesh. Instead of chlorophyll, the green seeds are chock-full of protochlorophyllide, a highly fluorescent molecule that glows orange-red under ultraviolet light and can be converted into chlorophyll a by an enzyme in the seeds. The enzyme reduces protochlorophyllide to produce chlorophyll when the enzyme encounters light, which occurs only after the seed has left the pumpkin and therefore needs to start producing its own food so it can grow. Helmut Brandl, a science communicator and professor at ETH Zurich, extracted this protochlorophyllide by grinding up pumpkin seeds and mixing them with nail polish remover (bottom row).
