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.
From powering aeroplanes to replacing nuclear energy, algae has been touted as a green energy miracle. So if our waterways are already filled with the stuff, why isn't it filling the world's skies with biofueled planes? Algae is a tricky creature that presents a lot of challenges and misconceptions. Here's why it's difficult to harness -- and why it could big a big payoff.
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?
For as ubiquitous as connectivity has become and how reliant we've grown on it, the internet is still a digital jungle where hackers easily steal sensitive information from the ill-equipped and where the iron-fisted tactics of totalitarian regimes bent on controlling what their subjects can access are common. So instead of mucking around in public networks, just avoid them. Use a VPN instead.
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.
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.
If you use Google's new Photos app, Microsoft's Cortana, or Skype's new translation function, you're using a form of AI on a daily basis. AI was first dreamed up in the 1950s, but has only recently become a practical reality -- all thanks to software systems called neural networks. This is how they work.
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?
