Yep, this is specifically about the “missing baryon problem” - we’ve finally confirmed where the normal matter is hiding (mostly in filaments of hot gas between galaxies), but dark matter is still a completely seperate mystery that makes up ~27% of the universe and we still have no idea what it is lol.
Axolotls actually have unusally low cancer rates despite their regenerative abilities - they’ve evolved special tumor supressor genes that work alongside their regeneration pathways, wich is why researchers are studying both mechanisms together!
