13 Hidden faces
|
view preview
This is a famous optical illusion, known as the '13 hidden faces'. It is also an attractive piece of art. How many can you find? It is considered that if you can find 10 faces you have normal powers of observation. If you find 15, you have above average observation skills, if you discover 21 or more, you have extremely keen observation skills. The faces that are most obvious are the ones in the foreground, along the path. They are lit up and our eyes are drawn naturally to them. The faces in shadow are perhaps more tricky to observe. Let me know if you find more, here are my solutions   ...

Asteriod impacts
|
view preview
The third largest asteroid to ever hit earth has been found in South Australia. According to scientists involved, the asteroid, which measured up to 20 km across, hit Earth approximately 360 million years ago. This was around the time of the Late Devonian mass extinction, strengthening the idea that asteroid impacts have been associated with many mass extinctions throughout the history of life on Earth.

Metal melts in your hand almost instantly
|
view preview
Gallium is a silvery metal with atomic number 31. It is used in semiconductors and LEDs, but the cool thing about it is its melting point, which is only about 85 degrees Fahrenheit. If you hold a solid gallium crystal in your hand, your body heat will cause it to slowly melt into a silvery metallic puddle. Pour it into a dish, and it freezes back into a solid. While you probably should not lick your fingers after playing with it, gallium is not toxic and it will not make you crazy like mercury does. And if you get tired of it, you can melt it onto glass and make yourself a mirror. ...

The Midas touch
|
view preview
Mythical King Midas was ultimately doomed because everything he touched turned to gold. Now, the reverse has been found in bacteria that owe their survival to a natural Midas touch. Delftia acidovorans lives in sticky biofilms that form on top of gold deposits, but exposure to dissolved gold ions can kill it. That's because although metallic gold is unreactive, the ions are toxic. To protect itself, the bacterium has evolved a chemical that detoxifies gold ions by turning them into harmless gold nanoparticles. These accumulate safely outside the bacterial cells. ...

Short-circuit your brain
|
view preview
Your brain is trying to do two things at once. Look at the image and try to say the colour of the word you see, rather than the actual word itself. It’s very tricky to do. The words seem to wrestle in a bizarre power struggle with the colours. This is because the right side of your brain is seeing the colour of the word while the left side is trying to say the word itself.

Barbados thread snakes
|
view preview
At first, it just looks like a worm. But when you peek closer, it slithers like a snake. It sticks its tongue out like a snake. It creeps you out like a snake. Discovered under a rock in 2006 in Barbados, this thread snake is as thin as spaghetti and smaller than any of the 3,100 other known snake species. Researchers believe it is the smallest a snake can evolve to be.

Amputations will now be a thing of the past
|
view preview
The very first bionic hand that allows the amputee to actually feel what the hand is touching will be transplanted later this year. According to doctors involved in the surgery the hand will be attached directly to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves. This will allow the patient to control the hand directly with his thoughts, and receive sensory signals to his brain from the bionic hand. This will be a major breakthrough in prosthetics and could open the door to a new generation of artificial limbs with sensory perception. ...
