Usually, humans hear through a process called air conduction, wherein sound pressure waves disturb the air and kick off a whole Rube Goldberg sequence involving our ear canal, eardrum, ossicle bones, and cochlea. However, Navy researchers discovered that, when there's no air to be disturbed, the sound skips the middle ear and resonates through the mastoid, which is the bone right behind your ear. This process is called bone conduction, and there are already hearing aids and headphones that use it:

If you turn it way up, you can hear your brain jiggling around your skull.
This means that, underwater, we all take on the ability to hear a whole new world of high-pitched sounds that you were never even aware of because, well, how often are you underwater in the vicinity of creatures making those kind of noises? Go for a swim in the ocean and really listen this time -- you'll be able to command that shit like Aquaman before you know it.
Your Skin Can "Smell" And Heals Because Of It
Aromatherapy is one of those things you only do because your significant other has a friend from the office who recommended it, and you're in a relationship that needs breaks like this or else you're not sure if you can continue. Literally, that's the only possible scenario. But, does laying down in a smelly room while getting an overpriced massage actually help improve your health? Up until now, the answer has been an empathetic "hahaha no," but researchers may have just proved otherwise, thanks to a mysterious substance called Sandalore. You know, this crap:
This isn't complimentary chocolate? Uh-oh.
German scientists have recently found that some of the cells that give your nose its ability to be a nose (that is, to smell) also exist in the skin. So, yes, your skin can smell -- as if being in the lower back regions wasn't undignified enough already. While we don't actually perceive what the skin is smelling, this process still serves a productive purpose. When the researchers exposed skin cells to Sandalore (a synthetic sandalwood scent), they found that it generated a 32 percent boost in cell division. Those cells can then go and help heal anything that needs to be healed, which should make all those spa knife fights a lot less dangerous.

Wolverine doesn't really smoke cigars; that's actually an incense stick.
But here's the catch: The concentration of Sandalore needed to trigger that reaction was 1,000 times higher than what it takes for your nose to detect the fragrance, meaning that you're probably gonna need a gas mask if you wanna try this. Nonetheless, it's interesting that aromatherapy isn't quite as much a junk science as it's been believed to be. Well, shit, what else are the hippies right about?
