  • Drinking alcohol is like borrowing happiness from tomorrow.

  • Assuming all goes well, you and your friends have a good time, and then the next morning

  • you're paying that debt back in the form of a hangover.

  • And trust me, the older you get, the steeper the interest rate.

  • Why isn't there some miraculous pill I could take that lets me do what I want without any

  • consequences?

  • It turns out there might be, the catch is it's only for mice at the moment.

  • First let's talk about hangovers, just to get it out of the way as soon as possible.

  • Don't worry, I'll dim the lights and talk quietly.

  • Alcohol plays a number of tricks on your body that set you up for a rough morning.

  • It tells your pituitary gland to stop producing vasopressin, a hormone that helps you retain

  • moisture.

  • Without it your liquids go to your bladder, which is why you have to pee all the time

  • when you've been out drinking.

  • Fast forward to the next day and you're dehydrated like the plants in my house I keep

  • forgetting to water.

  • You've peed away things your cells and muscles need to function -- like salt, magnesium,

  • and potassium.

  • And your other organs have stolen water from your brain, causing it to literally shrink

  • and pull on the membranes that attach it to your skull.

  • Consequently your head feels like it's being crushed by a Mountain, it's like being Oberyn

  • Martell.

  • Now on top of all that, there's a byproduct of alcohol that can make hangovers even worse.

  • The most common way your liver breaks alcohol down is a two step process, and unfortunately

  • the first step turns alcohol into acetaldehyde.

  • Acetaldehyde is highly toxic and makes your headache and nausea worse.

  • Oh, and it's a known carcinogen.

  • If you're drinking at a moderate pace your liver can break it down into the more benign

  • acetate.

  • But drink too much and the enzymes can't keep up, so we get a buildup of this nasty

  • acetaldehyde.

  • So with that in mind researchers have been trying to give your liver a hand.

  • Inspired by how the liver cells work, they created a combination of three enzymes to

  • neutralize alcohol: alcohol oxidase (AOx), catalase (CAT), and aldehyde dehydrogenase

  • (ALDH).

  • The first two break the alcohol down to acetaldehyde, and the last one is the same enzyme your body

  • uses to turn acetaldehyde into acetate.

  • These enzymes are nothing new, but the real trick was figuring out a safe and effective

  • way to get them to the liver where they could provide reinforcements.

  • The researchers chose to wrap each of the enzymes in a protective shell that's already

  • FDA approved, creating nanocapsules of enzymes that would build up in the liver.

  • You can't go straight to testing something like this in humans, so the researchers used

  • drunk mice instead.

  • Now I don't know how they got the mice drunk, but I like to imagine teeny tiny shot glasses

  • were involved.

  • Anyway once drunk and passed out, the researchers injected the mice with their triple enzyme

  • elixir.

  • In four hours the blood alcohol level of the treated mice dropped 45% more than the untreated

  • ones, and acetaldehyde levels stayed extremely low.

  • This could be a major boon not just for the shambling Sunday morning masses, but for emergency

  • situations like alcohol poisoning too.

  • Right now treatments for alcohol overdose mostly rely on the body's own pathways to

  • break down alcohol.

  • The fast elimination of the carcinogen acetaldehyde could reduce the risk of cardiovascular and

  • liver cancer as well.

  • The next step is making sure these nanocapsules are safe with no unforeseen side effects.

  • If testing goes well on animals, clinical trials on humans could start as soon as 2019.

  • Until then, just remember what's lurking for you

  • A saline drip is supposedly a miracle hangover cure since it rehydrates you intravenously,

  • but it turns out the saline we use is based on terrible science.

  • Find out why here.

  • Did you know darker liquors can cause more severe hangovers because of the impurities

  • called congeners that give them their color.

Drinking alcohol is like borrowing happiness from tomorrow.
