PET Tech here, answers to all the questions: -The isotope attached to the sugar is fluorine-18 -F18 emits positrons, which annihilates into two photons at 180 degrees, which is what the camera detects. The camera also takes a CT image that provides a map of the body that the PET is overlaid onto -The tracer naturally decays and also leaves the body through the urine, it’s indistinguishable from background radiation within 12 hours -The cameras cost 1 to 2 million, each injection costs a couple thousand since it has to be produced by a cyclotron -They were correct that cancer is far less common in cells that reproduce less rapidly (which is why the heart is extremely rare) -Yes, contrast can go in the butt. No, I don’t want to talk about it.

[@probablyaparent]

Oh man, I can fill the contrast in the butt part from the patient perspective. They insert a little bulb and inflate it so it stays in place while they pump in the contrast. It's horrible. 0/10 - don't recommend. (Thanks for your work, good folks like you are keeping me alive)

[@Problem-attic]

I love that you can use the term annihilate casually here, gotta appreciate good jargon when you see it :)

[@abigailsemple4985]

Love this, top 3 Safety Third episode ever. When I was a high school science teacher I got a massive amount of street cred with my students by telling them that Hank Green was in my college chemistry class (true story).

Spoiler, but that’s a not-insignificant plot point in Harry Potter and the Methods of Rationality, which depending on the metric you choose, may be considered the most popular HP fanfic ever. (Although it was written as a piece of philosophical propaganda as much as anything.) I was reading a follow up meta fanfic where they chased down the probe using magic-enhanced spaceflight a couple weeks ago. Although voldy in that story also has some invisible lighter than air horcuxes floating in the upper atmosphere, and one made of enchanted lead (iirc) that was dumped through a volcano where the earth’s crust is thinnest so it’ll float around the mantle forever, which might be harder to hunt down than voyager.

"My teacher really hated me for some reason..." "because you're *William Osman*, no I get it." Hank Green winning the internet over and over. Man was on fire just before his standup, can't wait to see the show.

[@ConnorTheRed65]

PET scan: Radioactive fluorine is attached to glucose which is injected into a vein, glucose is taken up by cells that use glucose for energy (most organs, but significantly more in cancer cells). Radioactive fluorine decays and emits positrons, positrons collide with nearby electrons and undergo annihilation, firing two photons at 180 degrees apart. Those photons hit the ring of crystals which surround the patient, crystals convert photons to electrical signal, signal sent to computer to reconstruct into image. Overlay map of radiation events over a CT scan acquired concurrently. They're super neat!

[@CockatooDude]

Ahh ok this makes way more sense now. The way they were talking about it was kind of nebulous.

The poem Alan referenced was "Harlem" by Langston Hughes. The play "A Raisin in the Sun" by Lorraine Hansberry about the same themes gets its title from one of the lines in "Harlem."

There is A great video by Jacob Geller that covers head transplants, and where ones "soul" or "self" resides when their brain turns off. It includes A clip from one of the new wolfenstien games where someone makes this exact case, that who you are when you wake up is not the same instance of "running" your brain and so it is not the same you. It was my first exposure to this fascinating fact.

[@Evelyn80264]

I've had the same idea. your consciousness ends when you sleep, but a new one is made with all the same memories stored in your brain, and all the same thinking and logical processes because it's all just a neuron circuit. so with teleportation, you would end the conciseness entering the teleporter, then create a new, identical one at the location you are recreated at. so from an outside perspective it's the same person, and as the person teleported, you have an identical brain so you know what happened and are the same person, but there is kind of another consciousness lost in the process.

[@NoConsequenc3]

@@Evelyn80264 there is no reason why any arbitrary change, even in external sensory input, isn't the level of change needed for a "new" you. All change is death. All time is change. Death is an extant form of life, in many ways.

I had Aplastic Anemia treated with a Bone Marrow Transplant. The process for me was less severe compared to someone with Leukemia because my bone marrow was already weakened. I got 5 doses of Chemotherapy and 1 dose of radiation to kill what was left of my marrow. My new bone marrow came from someone who had an 8/8 match with me which is very fortunate. What’s nice about bone marrow transplants is that you get to ween off the immune suppressant drugs that you need for other organ transplants. This is because you have a completely fresh immune system. When I say completely I mean it. I had to get re-vaccinated for every disease that I had been before the transplant. Bone Marrow Transplants are not perfect but they are a very matured process that’s been around since the early to mid 20th century.

It's kind of amazing how much heavy medications will change someone's hair. Hank shows that a lot, not necessarily in a bad way but since he's so prominently on a visual medium it's noticeable.
