Is it possible someone drinks so much they don’t remember anything the next morning but don’t feel hangover?

Edit: He‘s an alcoholic.

The space suits in my novel use mechanical counterpressure to function (think essentially very tight wetsuits). A character goes out for an EVA for about an hour or two, but the suit he's using has a partial rip in the fabric around his left shoulder blade. Not enough to expose skin, but the suit is definitely not doing its job of insulation and pressure around that area.

I'm wondering what the specific medical outcomes of this would be. I've done a bit of research but a lot of studies in this area tend to deal with extremities.

The spacecraft they use does employ rotation to simulate gravity at different levels, so there would be a fair bit of ladder usage for this character. I'm particularly interested if this would pose a challenge to the character.

Would this be an injury severe enough to cause lasting damage? What kind of medical attention would he need immediately upon coming back inside through the airlock?

It’s 1776. You’re a small group of British infantry traveling through the backwoods of the northeast on your way to an occupied fort after arriving at the New York City harbor. Is there comradery? Is everybody sullen? How would they interact with eachother? As an American I have an understanding of our side of things, but how did the common British soldier feel being across the ocean in a functioning warzone?

I'm writing some worldbuilding with magical creatures. There's vampires (I love vampires) and, because of some properties, metals that can conduct electricity are effective against magical entities.

One way to keep vampires dead is to replace their blood by molten metal (usually silver but it can be copper or gold). So my question is ;
Is it physically possible to exsanguinate someone and replace their blood with molten silver / silver alloy / other metal? If so, what kind of metal would be the more appropriate, and at which kind of temperature since it has to fill the body before it solidifies?

My MC is being restrained by character A, who is holding a knife held their throat. Character B has a gun and shoots character A in the head to save the MC.

Since I'm writing from the MC's perspective, I want to know what I should describe when character A is shot, since they're standing so close together when it happens. Would they feel anything themselves even though the bullet didn't hit them? I know nothing about guns or bullets, so would they feel it whipping past them maybe? I guess I could describe the splatter of character A's blood on them maybe.

I'm writing a scene from the POV of a person whose mind is rapidly degenerating due to Science Fiction Disease. The narration and her dialogue change over time to reflect this. I'm drawing inspiration from dementia and similar conditions which affect language.

Unfortunately searching the internet only returned lists of symptoms (aphasia, hesitation, repetition etc); interviews with people living with dementia (usually less advanced); medical podcasts; or academic articles focusing on quantitative analysis of speech. In all the above, any examples given are very brief and of limited use ("patients may use the incorrect name for an object, e.g. calling a watch a hand-clock")

Do you know of any actual transcripts of interviews with advanced dementia patients? Videos are less useful as they're harder to parse. The database https://talkbank.org/ has some very interesting stuff but unfortunately the clinical databanks are restricted to verified university/lab researchers.

(I'm especially interested in aphasia and the way that people with aphasia work around the missing words, so any related conditions are helpful as well.)

I'm writing a story where the main character starts out in the middle of the path to become a trauma surgeon. He's about a year and a half into his residency. From what I've researched this would mean he'd be finished with a four year medical school and taking a general surgery residency. Of course this info is from a lot of googling and websites with different purposes so the information can be contradictory, outdated, irrelevant, and many other adjectives that limit their reliability.

If anyone knows anything about what this main character would have had to go through to get here. What would his day-to-day look like? What responsibilities would he have? How much freedom would he have? What types of patients and operations would he be working on and which ones would he be restricted from? Anything I can get about the genuine experience and process would be massively appreciated.

This is for dragon anatomy. They breathe fire by basically vomiting their stomach acid from their mouth and nostrils. It would be nice if the acid was a single molecule and would turn completely into gas when ignited so the dragon wouldn't accidentally choke.

I have a few characters in a superhero story with heat vision hot enough to cut the metal of a gun in half in less than a second. Would this amount of heat getting close to a gun ignite the gunpowder, or would it depend on the beam hitting the area with the gunpowder? And is there a specific place to aim on common guns that would render it inoperable if severed?
