A severed mosquito proboscis can be turned into an extremely fine nozzle for 3D printing, and this could help create replacement tissues and organs for transplants.
I’ve linked to a decent write-up on Tom’s Hardware, but New Scientist covered it last week too.

I challenged my family not to say WHAT! when reading that headline. So far, everyone’s failed (including myself).
