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...

What looks like an octopus and stinks likes a skunk?
|
view preview
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. ...

Never trust a mirror
|
view preview
Can you figure out this optical illusion? Squares are magically turned into circles, then vice versa. But interestingly, it's not strictly the mirror that is fooling you - it's a combination of the shapes used and your fickle perspective. The trick was designed by Kokichi Sugihara from Meiji University in Japan for the "Illusion Of The Year" competition. You can see the other top 10 finalists from the competition right here. ...

Watch how the ancient Babylonians tracked Jupiter in the sky
|
view preview
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, ...

Fake it till you BECOME it
|
view preview
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.

The ghost fish has been captured on video for the first time
|
view preview
A living, swimming ghost fish has been seen live for the first time ever. The fish, part of the family Aphyonidae, was caught on camera during an ongoing National Oceanic and Atmospheric Administration (NOAA) exploration by the ship Okeanos Explorer. The exploration centers on the deep ocean at Mariana Trench Marine National Monument, a protected area spanning 95,216 square miles (246,608 square kilometers) east of the Philippines. The secretive fish was swimming along a ridge 8,202 feet (2,500 meters) down, according to NOAA. The animal is about 4 inches (10 centimeters) long, with translucent, scale-less skin and eerie, colorless eyes. No fish in the family Aphyonidae has ever been seen alive before. ...

This nerve bypass procedure enables a quadriplegic man to move again
|
view preview
After a broken neck left him quadriplegic, Ian Burkhart was told he would never be able to use his hands. Now he can grasp a bottle and pick up a credit card by using a computer plugged directly into his brain. Special software is able to decode his thoughts and convert them into electrical signals in his hand, bypassing the damaged nerves in his spine. Now Ian has regained an amazing degree of control over his hand, each movement stimulated by his own thoughts. https://www.youtube.com/watch?v=0I_q_dFtPhU ...

As this hawk-moth feeds on flowers and makes a similar humming sound, it looks a lot like a hummingbird. What’s interesting is that it is surprisingly good at learning colors.

Why do hard liquors keep you warm?
|
view preview
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. ...

Check out the footage of this tricky plant
|
view preview
To tap into scarce water supplies, most desert plants have extensive root systems that burrow deep or spread wide. But one desert moss has a different trick up its sleeve: a thirst-quenching structure called an awn. Awns are tiny, hairlike structures that project from the end of each leaf to capture water (above). For the first time, scientists have examined in detail how this moss ( Syntrichia caninervis) pulls water right from the air using its awns. At the smallest scale, the awns are covered with grooves about 100 nanometers deep and 200 nanometers wide, the perfect size for dew to condense within them when conditions are right. Those nanogrooves lie within larger troughs that measure about 1.5 micrometers deep and 3 micrometers wide, a ...
