Okay no. Fucking no. You think your sandwich is cute with peanut butter and jelly hearts, fucker? Well you’ll change your mind once you put it together and try to eat it. First you’ll get a mouthful of just bread and disappointment, then when you take another bite your mouth will be assaulted by copious the amounts of sticky peanut butter and sugary jelly and there won’t be enough bread to save you from it. A sandwich like that is what failure tastes like. The pb and j may be shaped like hearts but there’s no love in that sandwich. It’s about balance. Life needs balance, and so does your fucking sandwich. You disgust me. Don’t talk to me until you know how to make a proper sandwich.
You can also buy a poster design of the graphic, featuring just the coloured test tubes, on the site store.
Fun fact of the day: Mn2+ salts tend to be even fainter pink than what the figure actually shows, to the point where it looks white. This is because a lot of Mn(II) complexes are high spin, which results in one electron residing in each of Mn’s d orbitals with all having the same spin. Electron excitations in this case aren’t allowed, as a promotion would lead to two electrons with the same spin in the same orbital (which is forbidden by the Pauli exclusion principle). This results in a nearly colorless complex. :D
Cutaneous Loxoscelism, more commonly known as a Brown Recluse Spider Bite. How does the venom of such a tiny creature do this to a person? The spiders venom contains many cytotoxic substances but the main active ingredient is called Sphingomyelinase D. Sphingomyelin is a common lipid component of the cell membrane in humans, and this enzyme locks onto it and destroys it by converting it into ceramide-1-phosphate. We don’t know exactly what happens after this, but we think the continuous destruction of sphingomyelin results in the destruction of the cell, and therefore Brown Recluse bites cause widespread necrosis of the affected tissues.
