This salve would need to have some sort of magical property or ingredient for it to be that effective. Though there are some real herbs that help the body heal, none of them are anywhere near effective enough to heal that fast. My recommendation is, if you have some sort of magic in place, to try to use that to explain the salve's healing properties. If that ...

I've come to the conclusion that none of the blood pigments we have on earth have immunity to ammonia poisoning. In fact, an ammonia-water solvent with any significant amount of ammonia isn't something that is possible in an organism unless they have completely different biochemistry from us (though our bodies do produce very small amounts of ammonia, it is ...

Yes, but... ... we use industrial processes for a reason. Production, recycling, and manufacture boil down into "synthesis" and "extraction", and are different areas, so we'll examine them individually. Ultimately, it's best to have both playing to their strengths. Synthesising (from provided material) Let's look at making a conventional ...

Optical synapse The synapse is still an important step in the signal process, allowing for a lot of information modification. To keep this information modification, I would propose an optic synapse. The idea is simple. instead of chemicals, light is shone via a bioluminant lamp in the synapse gap. On the other end, photo-receptors will get agitated, ...

the brain spent two hours without oxygen. If you are aiming for realism, the patient is dead. Most neuroscience works state the survival rates for over 8 minutes of hypoxia ranging from very unlikely to impossible. Some quick googling leads to results such as this, which states that: At 15 minutes, survival becomes nearly impossible. And if the brain is ...

You propose acetylene as a glucose substitute. That has been mooted elsewhere on this stack. Yes yes, well and good. But what about cyanide? https://en.wikipedia.org/wiki/Hydrogen_cyanide CH4 + NH3 → HCN + 3H2 Cyanides exist on Titan and presumably other planets with reducing atmospheres like yours, and like the early Earth. The formation of CN is ...

/Will the patient come to life if some neurons are replaced with new, live ones grown in a test tube?/ Maybe. https://www.ign.com/articles/2019/05/31/swamp-thing-explained-who-is-the-dc-character What can reverse death? In Swamp Thing, a man died in the swamp and his form and his memory were copied by the life of the swamp. This new thing came back as an ...

You're going about this the wrong way. There's no reason to remove the substance from the body. Simply deactivate it. Most medications administered in a medical setting, especially the dangerous ones, have some group of medications that can be administered to counter the effects of the former. Too much caffeine? Try a central nervous system depressant. Too ...

You can use $H_2S$, as it is used by anaerobic bacteria on Earth Hydrogen sulfide is a central participant in the sulfur cycle, the biogeochemical cycle of sulfur on Earth. In the absence of oxygen, sulfur-reducing and sulfate-reducing bacteria derive energy from oxidizing hydrogen or organic molecules by reducing elemental sulfur or sulfate to hydrogen ...

There was a good article about this a while back: https://foresight.org/Nanomedicine/Respirocytes.html Now, this was talking about artificial respirocytes, but the general concept remains. Long story short: whereas red blood cells mainly store O2 in solution and/or chemically bound, if you store O2 under pressure instead you can achieve a much higher ...

Using a blood substitute you could improve this. Perfluorochemicals can carry several times more oxygen than red blood cells. They could be adapted for that. Along with other minor efficiency boosts, this could let them survive longer underwater.

Circulating peroxisomes carrying O2 as H2O2 synopsis: H2O2 is a concentrated liquid source of O2 gas with available O2 increasing as concentration of H2O2 increases. Stores of oxygen as H2O2 could be tapped during long breath holding. All hail the peroxisome, ancient armor of our ancestors! https://en.wikipedia.org/wiki/Peroxisome Peroxisomes are tiny ...

Swimming Like a Seal: I'm not sure hard science is the best fit for this question, but I'll give it a go. I think the key element you are looking for is aquatic mammalian myoglobin. There is a good set of review articles here on the subject. The biochemistry gets pretty technical, so dig in deep to the second link to get the hard science. Basically, cetacean ...

Work backwards from your humanoids. source Any kind of life could be on an alien planet! But you have humanoids and you have given them some thought. Make some sketches of how they look. Draw their skeletons. There is one thing we know about the animals of your world - one of them evolved into these humanoids. Others probably have a body plan similar to ...

Flesh puddle Nitrogen is an integral element of nucleotides, which make up DNA and RNA. Cells wouldn't die instantly without DNA; on the shortest timescale and among other things, DNA is a template for RNA, which in turn is a template for protein. This individual's body now lacks not only the templates for transcription and translation, but also the ...

Congenital methemoglobinemia could be protective against red cell parasites. The red cell is a less hospitable place in persons with congenital methemoglobinemia. https://ashpublications.org/hematology/article/2005/1/19/19272/Red-Cell-Enzymes Homozygotes or compound heterozygotes have methemoglobin concentrations of 10% to 35% and appear cyanotic but are ...
