Science fiction taught us that when science starts modifying the human body, it's going to involve robot parts and genetic modification gone terrifyingly wrong. But the reality is that the body modifications that are right around the corner are way less frightening and quite a bit more useful. It won't be too many more years before a trip to the doctor can ...
5 Change Your Eye Color
We'll wager that there are more than a few brown-eyed people out there who feel like they got the short end of the genetic stick. However, eye color is one of those things that you probably thought science could never change. Sure, you can wear colored contacts and pretend you've got blue, gray, or freaking ThunderCats-themed eyes, but the illusion only lasts until you remove the lenses. Well, now there's a doctor in California who claims to have invented a procedure that can permanently turn those dull-as-dirt brown eyes into mesmerizing baby blues, and all it'll take is 40 seconds of your life (plus several thousand dollars).
There are worse ways to spend thousands of dollars in 40 seconds.
How is this even possible, you ask? Does it involve some kind of horrifying eyeball tattoo gun? Actually, it turns out that, technically, everyone has blue eyes. It's just that for the majority of us, our mundane genes decided to squirt a whole mess of brown pigment on top of the blue. But now Dr. Gregg Homer has arrived, laser-guided pigment bomb in hand, to tell your genes to get bent.
Basically, the procedure consists of laser-burning the shit out of the brown pigment in each of your eyes. Then, since your body never planned for the eventuality of sci-fi death rays attacking its irises and therefore never thought to keep an extra supply of eye pigment on hand, it decides to simply chuck the damaged pigment out. In two or three weeks, all traces of brown disappear, and you're left with eyes worthy of a crooner.

With none of the raging alcoholism.
We're sure many of you are scrambling to have your eyeballs lasered by a doctor who sounds like a gag from The Simpsons as soon as humanly possible, but don't get in too much of a rush -- the procedure's still in the testing stages. The good news, though, is that all preliminary tests have turned out well, at least according to Homer. He's tested it on animals, cadavers, and Mexicans (seriously), all without a single complaint. The better news is that if you just can't wait until the procedure gets the official OK from The Man, you can head straight to the not-at-all-evil-sounding Stroma Medical website and volunteer to be a guinea pig for one of the good doctor's trial runs.
A word of warning: As of now, the procedure is permanent, so if for some reason you find your new appearance freakish and want to change it back ... tough shit. Freak.

4 Regrow Your Teeth
As long as there are such things as old people, hockey pucks, and Pixy Stix, tooth loss will remain a concern for us humans. After all, when a tooth is broken or falls out, it's not like when you cut your nails or shave your beard -- that shit ain't growing back. Well, actually, that might not be the case for long, as there are not one, but two teams who've set their sights on taking down the denture industry by regrowing your very own teeth right inside your very own mouth-hole.
So kids: Borrow your dad's pliers and bleed that fairy dry.
First, there's a team from the University of Alberta in Canada (where hockey-related tooth loss strikes virtually every male before age 15) who say they've managed to regrow broken teeth by using ultrasound emitters. Seriously, they just point sound waves at your teeth and they grow back. The procedure worked so well on rabbits that the scientists figured, screw it, why not scale up the difficulty and try it out on an animal whose entire diet isn't just cabbage and water? So they tested a variant of their ultrasound method on humans and found that it worked, even when the root itself was damaged. The system consists of a "miniaturized system-on-a-chip" that constantly barrages the root of your tooth with good tooth vibes as you wear it inside your mouth, and in no time ("no time" meaning "about a year") you're right back to popping beer bottle caps with your pearly whites.

Which also happens to be the mating call of Alberta, Canada.
More recently, a bunch of researchers from Columbia University and Nova Southeastern University in Florida have said they can regrow teeth using dental stem cells. When a patient loses a tooth, the docs simply plop some dental stem cells into a tooth-shaped scaffold and wait for the stem cells to work their magic. The patients can grow the new tooth either inside their own mouth or outside the body, but either way, within nine weeks they've got themselves a shiny new food masher. And no, the stem cells being used for this procedure don't come from embryos. Instead, they're collected from discarded teeth or other "dental waste," which we sincerely hope isn't as gross as it sounds (but probably is).
