0. WASH YOUR GODDAMN HANDS.

We're not working in a lab here, cross-conatamination WILL happen. Your job is to minimize it as much as possible. If you end up in a place where soap hasn't been invented yet, wash your hands in distilled alcohol. Your skin won't thank you, but you can afford all the nice hand creams after you cure the plague and get rich.

Find some Penicillium mushrooms!

Yes, penicilin is produced by mushrooms, though Ascomycotes are usually called moulds, it's a fungus, and it makes me laugh to call it a mushroom. Plus, in the middle ages, mushrooms were known to have medicinal properties, so you'll get a lot farther by calling them mushrooms rather than molds.

First thing you need: mouldy fruit. Oranges, or cantaloupes are preferred.

Here's the thing: mold is everywhere, so getting it will be the easiest part. The tricky part start with identifying the correct mold. You don't want to feed your patients black mold, do you?

So. Leave some fruit out. The more the better, because you want to up your chances. Then let it rot in warm and humid places. After a while, pick any fruit that looks white on the outside and green in the middle:

Not the best picture, but that's what it should look like.

2. Transplanting your (potential) Penicillium mushrooms

Until you get it on a plate it's damn near impossible to tell which mold you got. Get ready for some trial and error because you will have to sift through a lot of unwanted mold. You might want to wear a mask.

First you need something to transplant it onto. Making modern agar plates is probably impossible but thankfully not needed. You just need:

Glass plates (the kind that can be closed, you want to minimize cross contamination)

1-2 cup of Hot water (preferably distilled, ask your alchemist if he can do that)

1 cup whole milk (should be 13g of lactose per cup, if your Penicillium won't grow adjust the water-milk ration in favor of milk)

If available: Instead of milk use corn steep liquor. Unfortunately only available after America was discovered, so YMMW, but Penicillium LOVES this stuff. It will make your life SO much easier if it's available.

Pinch of salt

1 teaspoon Yeast extract (get it from a baker)

3-6 teaspoons Gelatin (get it from a butcher)

Disclaimer: The ratio of each of the ingredients will have to be adjusted depending on the purity of the ingredients and on the conventional measuring sizes of the place you end up.

Gently mix it all in and pour out into the plates, let it solidify. If you end up dumped far enough that such refinement isn't possible, make bone broth and strain it through cheesecloth several times to make it as clear as possible, then mix it 5/6 broth and 1/6 milk. Again, if available, use corn steep liquor, but if not milk is fine. Add gelatin (should still be able to get it from the butcher) as needed to solidify it. I'm afraid experimentation will be needed depending on the resources you will be working with.

When you're done, you should have something like this:

Now that you have your plates, run an inoculation loop through a flame to sterilize it.

Something like this. Wave it through the air to cool it so you don't kill your mold, grab it from your fruit and geeeeeently spread it on top of your improvised agar without breaking the surface of the gelatin!

You can see the motions on this one pretty well. Close your plates, stack them about a meter/3ft from the fireplace. Judge for yourself, but ideally somewhere you would consider comfortably warm (20-24°C).

3. Identifying your Penicillium Mushrooms

If all went well, you are going to have something that looks like this:

Well, realistically, it will look something like this:

We're not actually doing it in a lab, after all. But IDEALLY, it will look like the above. It doesn't have to be perfect, you just need to be able to identify Penicillium molds for now.

IDEALLY, on the plate that matches the description of the penicillium mold you'll see an exclusion zone of bacteria around the mold, like the fourth plate in the second row, so you know you have a potential winner, but if you managed to avoid bacterial growth you need to take a few extra steps.

Penicillium molds have characteristic rings of growth, grey-green-white rings. They're easy to differentiate from bacteria because the molds are fuzzy and the bacteria as smooth and slimy. In the above picture, there are four plates that potentially have what we want, and two are less certain than others. Wash out the unwanted ones, make new agar plates, sterilize your inoculation loop and transplant your best candidates. You might need to do this several times.

Two types are confirmed to produce penicilin: P. chrysogenum and P. rubens.

The former is far more widely used today, but since we're sourcing them from literally thin air, we're more likely to get P. rubens, but unless you're a mycologist you probably won't be able to tell the difference. Thankfully you won't need to, because they both produce penicillin. Which brings me to the next step.

4. Confirming it's the penicillin producing mushroom

We're gonna need more agar plates for this one, and believe it or not, you're gonna need to mix blood into your agar. Wash your hands THROUGHLY.

(Theoretically you can get away with just milk, but identifying the correct bacterial colony on white agar is going to be a nightmare, so just add some sheep blood to your agar, conventionally it's about 5% by volume but you might need more to make it)

You need some gram-positive bacteria, preferably of the Bacillota type. Please don't go out and find a patient with fucking botulism or tetanus, you need to live long enough to make the cure. Instead, if you have a vagina, scrape some of the white, mucousy stuff from there and plant it on your plate. If you don't have your own vagina, a borrowed one is fine. Penicilin also works on Treponema pallidum, so if you get a syphilis-affected prostitute that should also work. Just wear gloves.

Ideally you get something like this.

This is actually Lactobacillus brevis, but Lactobacillus colonies all look relatively the same. The important thing is that it's all gram-positive, and will therefore be affected by penicillin.

Take new plates again, plant your Penicillium mold in the middle, and the bacteria all around it, getting as close to the center as possible. You can put down a paper marker for the mold. Wait for about 20 days.

Ideally, on at least one plate, you will get something like this:

This is literally a textbook example of testing antibiotics, but the Zone of Inhibition is what you're looking for. It means the mold is releasing a compound to kill the competing bacteria for resources, in this case, Beta-lactam antibiotic, or penicillin. Make sure to pick the one with the WIDEST ZoI, because that's the one that produces most penicillin.

So now we have the root stock, but our problems have just begun. This is the part where you're absolutely going to need an alchemist's help.

The problem is that a human body is not a petri dish. It's quite a bit larger. And you want the good bacteria destroying stuff without all the nasty contaminants, so you need a SHITLOAD of mold producing a LOT of penicillin, and then you need a way to filter it. You are going to need actual lab equipment for that, or near as they had it.

i was incredibly dysphoric about my round face and softer features until i started looking at the faces of hispanic men and realized that those features weren’t feminine at all, they were ethnic features white supremacy had conditioned me to see as less masculine

Cambridge professor of sociology Jason Arday is accused of plagiarism by another academic

the accuser is a "race realist" who believes that in a true meritocracy all university professors would be white. this is somehow not acknowledged much during the entire ordeal

this leads to several days of media coverage demanding an investigation, or that Arday is expelled from his post immediately

somehow this accusation that has no effect on the lives of 99.99% of the population becomes FRONT PAGE NEWS in all the newspapers for multiple days, above anything else happening in the UK or the world at large

following intense media scrutiny, Arday resigns his post as a Cambridge professor

today, august 14th, days after resigning, Arday is found dead at his home in Battersea

This article by professor Kehinde Andrews clarifies more about the story of racist harassment Arday has been suffering since he fucking got a teaching job at Cambridge in the first place, in 2023, as the FIRST Black professor in that fucking stupid institution, who sure is taking it's sweet time defending their worker, despite already fucking checking his work for plagiarism and saying he didn't do it:

1. He wasn’t the first Black Professor at Cambridge, but he WAS the youngest X

2. He was ALSO autistic, and nonverbal for the first 11 years of his life X

She got the idea for the study while walking with her advisor at Stanford to discuss her thesis topic, and the paper she eventually published in the Journal of Experimental Psychology in 2014 is sharp enough that it should have ended the seated meeting on the day it came out.

She ran 4 experiments on 176 people. Same person tested twice. Once sitting, once walking. The creativity tasks were the standard ones psychologists have used for decades to measure how good a brain is at generating novel useful ideas.

81% of participants in the first experiment produced more creative ideas while walking than while sitting. In the second experiment, 88%. In the third, 100%. Every single person walked into a more creative version of themselves. On average, people generated 60% more novel useful ideas the moment their legs started moving.

The skeptical question is the obvious one. Maybe it was the fresh air. Maybe it was the scenery passing by. Maybe it was the change of environment doing the work, not the walking itself.

Oppezzo killed every one of those explanations with one experimental decision. She put people on a treadmill facing a blank wall. No scenery. No fresh air. No environmental change. Just legs moving in place while staring at white drywall. The 60% boost held.

Then she ran the experiment that closed the case completely. She took participants outside in two conditions. Half of them walked through a Stanford courtyard. The other half were pushed through the exact same courtyard in a wheelchair. Same outdoor stimulation. Same scenery passing at the same speed. The only difference was whether the legs were moving.

The walkers produced dramatically more novel high-quality ideas than the wheelchair group. The outdoors did almost nothing on its own. The walking did everything.

She also tested the opposite kind of thinking. Convergent thinking. The kind where there is one right answer and you have to narrow down to it. Word puzzles where 3 words share a hidden fourth word that connects them. The seated participants did slightly better on these. Walkers got slightly worse.

Walking is not a general intelligence enhancer. It does one specific thing. It opens up the divergent search inside your brain. The part that generates options. The part that produces unexpected connections. The part that takes a problem and finds five ways into it instead of one.

When you need to converge on the single right answer, sit down. When you need to find the answer in the first place, get up.

The mechanism is now well understood. Walking selectively activates what neuroscientists call the default mode network, the system inside your brain that runs when you are not consciously focused on anything. The DMN is where mind-wandering happens. Where memories cross-reference each other. Where ideas that have been sitting in separate folders inside your head finally bump into each other.

When you sit at a desk and force yourself to concentrate, you suppress the DMN. When you walk at a natural pace, the executive part of your brain gets just busy enough handling the walking that the DMN comes online and starts doing the work that focus was blocking.

The most useful finding in the entire paper is the one almost nobody quotes. The boost did not turn off the moment people stopped walking. Participants who walked first and then sat back down stayed elevated. Their next round of seated creativity work was still significantly better than people who had been sitting the whole time. The rest lingered for at least several minutes after the legs stopped moving.

You do not need to do creative work while walking. You need to walk before the creative work. The brain holds the state.
