Yippee! Let's poison ourselves with beverages that will make us violently ill! It was your battle cry last night, and today you're paying the price. But what is that hangover you're experiencing, exactly?

This year, Samsung will sell (at least) two phones and a watch that don't run Android. Instead, they will run something called Tizen. That's a major departure for such an important player in the smartphone game. But what is Tizen? And will you actually want to use it?

For three decades, most of us have interacted with computers in exactly the same way: We point with a mouse (or a finger!), click, and watch the screen. In one way, it's the most outdated element of human computer interaction around. But in another it's the thing that's shaped every operating system and device designed since its invention. We're starting to leave it behind though. Here's what's coming next.

The Copyright Alert System was conceived all the way back in 2011 as a new way to deal with seemingly unstoppable online piracy. It finally goes into effect in the US today, and it will impact a huge portion of American internet users. Sounds scary, but what is it exactly?

Did you hear about the HTC One's fancy new "UltraPixel Camera"? HTC touts the camera as an end to the "megapixel wars". UltraPixels! Revolution! And, yes, the technology sounds very promising, but, uh, wait a second, what is an UltraPixel anyway?

Ultra HD is marketing-speak for 4K or 8K resolution TVs. And that's more or less it. You're going to be hearing the term a lot this show though — and throughout the year — so here's a little more information about what exactly that means.

The human race produces 2.5 quintillion bytes of data every day — far too much to crunch using conventional desktop applications. Mining this mountain of data for nuggets usable information is one of the biggest challenges facing modern society. But a new generation of analytic tools are helping us control the phenomenon that's becoming commonly known as Big Data.

A gigantic storm is set to hit the US west coast later today, bringing with it over 30cm of rain. It's what meteorologists call an Atmospheric River — but what is that, exactly?

Israel got itself into a little mini-war in Gaza, and Hamas is firing off an extra dose of rockets into the Holy Land. What's (maybe) stopping them? Something called the "Iron Dome" — and what exactly is an Iron Dome?

The lustrous patina that protects the backside of Apple's new iPad Mini isn't just some cheap shellac or sealant coat — it's actually "grown" on the metal itself in an electrochemical process known as anodisation. Here's how.

To create the new iMac, Apple's thinnest desktop yet, the designers used friction-stir welding to going the aluminium body. Unlike arc welding, the more standard way to fuse metal plates, a friction stir just needs a good rubbing — and a few thousand pounds of pressure — to stick together.

Intel Clover Trail. Sounds like a JJ Abrams movie about camping, right? But Clover Trail is actually the next generation Intel Atom chip that'll power both Windows 8 tablets and laptops. Which means you'll probably run into this chip pretty darn soon, so get familiar.

Everyone really likes AirPlay, Apple's Wi-Fi streaming standard that lets you send movies and music from, say, your iPhone to your speakers or Apple TV. Now there's a new standard out to do pretty much the same thing for everyone else. But how is it different from previous attempts?

At today's Kindle Fire HD revealing, Jeff Bezos bragged that the Fire HD will be capable of downloading content up to 40 per cent faster than either the iPad or the Nexus 7. Neat trick, but how will it pull it off?

There is no shortage of platforms to post your ideas, photos, videos — whatever — online, but today we got another high-profile one. Medium announced itself with a lofty manifesto about publishing and media. But, um, what makes it different and why should anybody use it?

You wouldn't initially think it, but your phone's home screen is itself an app. It's an app that launches other apps — an app launcher, if you will. But if the app launcher native to your mobile isn't up to snuff, you can always replace it.

As expected, Microsoft just announced something called SmartGlass at E3. Less expected? Just how awesome SmartGlass turned out to be. What could have been just an Apple AirPlay imitation is something more ambitious; something that could change television forever. But what is it, exactly?
