After two years of work, Martin Molin of the Swedish band Wintergatan debuted a fully custom-made machine that plays music using 2,000 marbles. The marble machine features multiple instruments including a bass guitar, cymbals, and a vibraphone all played by falling marbles. Apart from the 11 mm steel ball bearing marbles, he made all the gears powering the machine by hand.

Anyone who has ever taken a shot of hard liquor (tequila, brandy) can tell you: it burns on the way down. But it's not the alcohol itself that's burning your throat. Instead, the ethanol in the liquid is making your throat's VR1 heat receptors (left) more sensitive, prompting them to perceive your own body temperature as hot.

Normally, the VR1 receptors activate at 42° Celsius, but alcohol lowers this threshold to around 34° C, which is 4° C less than your bodies regulated temperature.

Watch this guy get a tattoo as he explains the science behind the equipment and the pain.

So, does stress really cause your beautiful golden locks to turn silver?

Perhaps one of my favourite TEDtalks. Amy Cuddy’s research on body language reveals that we can change other people’s perceptions - and even our own body chemistry - simply by changing body positions. Her take-home message is simple, instead of faking it till you make it and living a life as an impostor, you must fake it till you become it.

It's hard to fathom the difficulties our ancestors had to contend with given how our world has advanced with technological sophistication over the past century. We shouldn't, however, underestimate the power of the human-mind, and how everything that was discovered in the past paved the way for the practices used today, especially those used in science.

Of the very first astronomers, the ancient Babylonian were the first to use simple arithmetic to predict the positions of celestial bodies. Evidence reveals that these astronomers, working several centuries B.C.E., also employed sophisticated geometric methods that foreshadow the development of calculus. Historians had thought such techniques did not emerge until more than 1400 years later, ...

The octopus stinkhorn mushroom (Clathrus archeri) looks like an octopus and stinks like rotten flesh in order to attract the flies that spread its spores. This fungus is indigenous to Australia, including Tasmania, and New Zealand, and an introduced species in Europe, North America and Asia.

As shown in the video, the young fungus erupts from a sub-erumpent egg by forming into four to seven elongated slender arms initially erect and attached at the top. The arms then unfold to reveal a pinkish-red interior covered with a dark-olive spore-containing gleba. In maturity it smells of putrid flesh.

Watch as one of nature's most efficient killing machines slowly chows down on the face of a fly as it writhes helplessly in its arms. It's the sound that really got to us...
