Health/Medicine

 1) Often called the "Medical Needle", they're usually the thinnest building in the arcology groupings because they're pretty much required in any major city, because they want to make sure people get as much windows as possible, and because they as many separate floors as possible (in case of quarantine or required lockdowns). The larger base might be thicker. 2) This is where major surgeries are conducted, cancer is treated, hospice is begun, and peculiar diseases are studied. 3) This is also where the local medical school is located, as stated, college, and potentially even secondary education is always adjoined with dedicated arcologies. It's efficient, and civilization is in a very experimental stage, so learning is quite simply part of everyday life. 4) Mentioned before, it might blur the line between research stations, it's often set up like one with laboratories, and a lot of devices meant to study, measure, and if need be, counter each person's abilities. 5) To be honest, most people can be treated the same way, which is why a lot of arcologies have medical modules and call it a day, but there are specialists for people with wings, gills, or have really hard skin. And there are definitely voyages into ways one can treat a telepath. 6) There's private and public facilities, and the difference between the two might be a gradient. They might be two different structures (the public one being a "hand me down"), they might be two needles from the same base, there might be wings, there might be subsidization, some might let students and researchers turn them into a guinea pig for a discount, there's charity, etc. 7) The ones who live there are students, and a few professors. Staff does not want to live there if they don't have to, they need to separate themselves from a stressful, often emotionally crushing environment. They do have apartments, which are usually long term pediatric patients and their parents. 8) The commercial decks are actually not incredibly different from those found in standard arcologies, with a few differences. There's overall less branding, except for cartoon characters (often posing with children meant to represent patients), they have things like carousels, movie theaters, petting zoos, laundromats, soundproof offices with zoom style screens for work. 9) Therapy is not stigmatized, and a part of everyday life, but there are unfortunately some individuals who are at a level of mental illness, which, combined with their powers, are placed in what is effectively a mental institution. The military might be stationed there. They are rare, and treated as a tragic last resort, except for a few oppressive regimes who are less empathetic, and might even send political enemies or dissidents there.
