  • Medical science can give you a new hip.

  • But how about a sixth sense?

  • You know, we humans are really aware of the five senses, right...

  • vision, hearing, smell, taste, and touch?

  • But that's just the tip of the iceberg. There are actually more senses that we have, and

  • some of them you've probably have never even heard about.

  • For example - proprioception!

  • That's your ability to sense the movement and position of your body parts even if your

  • eyes are closed.

  • Go ahead. Try it. Close your eyes, stick out your forearm, and try and grasp it with your

  • other hand.

  • Pretty cool, right?

  • Or what about nociception? That's your sense of pain.

  • Granted it's not in my top five, but it's still pretty important.

  • But then we can look to the animal world for some really cool senses, like magnetoception.

  • That is the ability to sense magnetic fields. Sea turtles, birds, and some other animals

  • have this ability. They can actually sense the Earth's magnetic field, which helps in

  • navigation for long migrations.

  • In fact, some birds might even be able to SEE magnetic fields like a grid overlaying

  • their vision!

  • Which just adds to the reasons to be jealous of them - on top of the fact that they can

  • fly, and they're allowed to poop on statues whenever they want.

  • Which I'm being told I absolutely can not do.

  • But what if we could expand our senses beyond the ones we already have?

  • For example, you could have a little bio-implant, a magnet made out of a rare earth metal called

  • neodymium, and that would allow you to sense electromagnetic fields.

  • Imagine it, an entire new world of sensation opens up to you!

  • Or how about a different magnetic upgrade? What about a compass that tells you when you're

  • facing north by vibrating?

  • So you don't look for the North Star, you just look for the north buzz.

  • And while we're upgrading, lets not stop with cyborgs, lets go full on superhero!

  • Some students at the Electronic Visualization Laboratory at the University of Illinois in

  • Chicago have built a spidey sense suit that they call

  • - drumroll please -

  • SpiderSense!

  • Here's how it works. It sends out ultrasonic signals, which when they come into contact

  • with objects, bounce back and are picked up by microphones in the suit.

  • Which then trigger a robotic arm to put pressure on your skin - alerting you to an oncoming

  • object. And they tested it out in a very scientific way.

  • They had someone dress up in the suit, put on a blindfold, and then get attacked by people.

  • And they fended them off with cardboard ninja stars.

  • SCIENCE!

  • Now this is just a basic model, but you can imagine a more advanced one being able to

  • tell you how far away an object is and how quickly it's coming toward you.

  • And if you don't want to be Spider Man, maybe you're thinking...

  • No! What I really want to be able to do is track Arnold Schwarzenegger through the jungle

  • using just his heat signature with my infrared vision.

  • But that is pure science fiction, right?

  • Wrong!

  • In 2013, researchers gave rats the ability to sense infrared signals through brain implants!

  • They put infrared sensors on the rat's foreheads and wired it to the touch center of the rat's

  • brains so they could actually sense infrared radiation.

  • I kinda want that.

  • And on the other end of the visual spectrum we have ultraviolet light. Imagine being able

  • to see the way butterflies can see.

  • Or lets go really crazy. What about tongue-like chemoreceptors on our skin, so you can actually

  • taste things with your hands?

  • Imagine all those delicious doorknobs...

  • But I have a question for all of you out there. If you could add a sense to the ones you already

  • have, what would it be?

  • Let us know in the comments below.
