What the hell is that? Seriously, did that just come out of you, or did it crawl up the pipe? If you've just exorcised a poo that looks nothing like what you've eaten recently, it could be a sign of a serious illness. It could also just be that curry from last Wednesday, so it's good to know what to look for.

Even as the body of evidence of cannabis' potential as a potent medical precursor grows (especially with the development of CBD-rich strains), smoking it is not without long-term side effects. And we're not just talking about munchie-induced weight gain either. A number of recently published studies suggest habitually getting high not only kills your motivation, it might even alter your brain chemistry. Specifically, the part that makes you want to get off the couch.

If you followed the news out of CES closely you probably heard the word HDR tossed around a lot. This coming year we'll see TVs for under $700 with the feature, and fancy monitors for over $1300. But what does HDR even mean?

Posture is not a rigid concept. It represents something more fluid with considerable range for change. Despite this, it is often oversimplified, rightly or wrongly, as being “good” or “bad”.

Everybody knows not to shine laser pointers in your eye. They could damage your vision! (Emphasis on could, since your eye's blink reflex would probably protect your retina.) But what if you were an evil villain determined to make a death ray? How many laser pointers would it take to create a deadly weapon?

There's at least one funny joke in the Jason Segel/Cameron Diaz movie, Sex Tape. While frantically trying to cut off access to the amateur porn vid he accidentally uploaded to iCloud, Jason Segel tries to explain why deleting the file won't work. "Nobody understands the cloud," he says. "It's a fucking mystery!" He's kind of right.

When a United Airlines flight made an emergency landing this summer due to medical situations on board, as the oxygen masks fell down, some passengers' phone cameras went up. But psychologists say the instinct to snap a selfie in a near-death experience isn't all narcissism -- it's also about survival and self-preservation.

"Screw you Apple, where the goddamn hell is my middle finger emoji?" can soon be conveyed in far fewer characters, thanks to the middle finger emoji that's coming to your iPhone. But why did it take so long? Here's how those middle fingers -- and all emoji -- make their way to your screens.

People are terrified that they're being exposed to radiation all the time, whether from distant nuclear accident or the mobile devices snuggled against their heads. Generally, they are wrong. Here are the most radioactive objects in the world around you, and the truth about which ones cause health problems.

Ever since Morpheus explained how the machines use humans as batteries in The Matrix, we've been fascinated by the idea. But can the human body actually generate enough current to do anything useful? We decided to find out, by asking experts how long it would take a human brain to charge an iPhone.

The most popular man-made material isn't steel, plastic, or aluminium -- it's concrete. But what the heck is concrete, really? That may sound like a silly question, but most of us don't actually know. Do you? If not, read on, because we have the answer.

On July 14, the New Horizons spacecraft will make history when it sails past Pluto, formerly known as the ninth planet. Even more incredible is how fast we got there. The spacecraft travelled 4.8 billion kilometres in nine and a half years. That's about 1.6 million kilometres a day for almost 10 years. How the heck did we do it?
