Happily disgusted? 15 new emotions ID'd
Until recently, scientists had only identified six basic human emotions: happy, sad, fearful, angry, surprised and disgusted. These "emotion categories," as cognitive scientists like to call them, are defined by the facial muscles we use to express each emotion. "The problem with that is that we cannot fully understand our cognitive system ... if we do not study the full rainbow of expressions that our brain can produce," says Aleix Martinez, an associate professor at Ohio State University.

Tongue Has a Sixth Sense
The human tongue may have a sixth sense—and no, it doesn’t have anything to do with seeing ghosts. Researchers have found that in addition to recognizing sweet, sour, salty, savory, and bitter tastes, our tongues can also pick up on carbohydrates, the nutrients that break down into sugar and form our main source of energy.

The insane things that insane people put themselves through to complete 100-mile marathons
The human body is a weird and amazing machine. It's easy to forget this, alone in the complacency and familiarity of one's own form and rhythms. But then one remembers the existence of runners with the mental and physical stamina to run a hundred miles or more at a stretch and soon the potential of the familiar starts to seem a lot more promising.

Do we really only use 10% of our brain?
As the new film Lucy, starring Scarlett Johansson and Morgan Freeman is set to be released in the cinemas this week, I feel I should attempt to dispel the unfounded premise of the film – that we only use 10% of our brains. Let me state that there is no scientific evidence that supports this statement, it is simply a myth.

How often do you need to see a dentist?
A lot of us think that we should visit the dentist every six months – even if it’s not what we do in practice. Whether those biannual check-ups are really necessary is, however, a matter of debate. In fact, it’s not even clear where the six-month figure initially came from. Some believe it dates back to the 18th Century, long before the advent of randomised controlled trials that could test its benefits.

Evolution: Why don’t we have hairier faces?
Have you ever stopped to consider your face? Compared to most of the rest of the animal kingdom, the human face has at least one really peculiar feature: it's almost completely devoid of hair. Sure, some people grow beards or moustaches, but even a full pirate's beard would leave quite a bit of skin showing. They don't call us "the hairless ape" for nothing. How did we come to be so bare-faced?
