This is a frilled shark. Frilled sharks are found throughout deep waters in the Atlantic and Pacific oceans. It is often described as a living fossil because of its resemblance to extinct, Paleozoic sharks. They are rarely seen alive because of their preference for deep water.

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. ...

This frog (Breviceps namaquensis) sounds like a bike horn.

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

Giant African land snails can get quite large. They are native to Africa and are routinely confiscated at airports as they are very popular as pets in the Western world, and can be considered an invasive species. There is a population of these snails spreading in Coral Gables, Florida.

Sunda pangolins have become the most frequently seized mammal in the illegal wildlife trade in Asia, as smugglers sell the creatures to meet culinary and medicinal demand. These gentle insectivores are now on the endangered species list.

Fasciculations (muscle twitches) are the result of some kind of irritability of the nerve fibers. Because fasciculations are benign, they have not been studied particularly deeply (but, not all involuntary muscle twitches are fasciculations--more on that later). So we do not really know even where in the nerve the irritation is picked up--it could be in the cell body, could be further out in the fibers, nobody really knows. It is also thought that the exact localization of the fasciculation is random, meaning that you will feel a twitch in your arm or leg or eyelid without having necessarily irritated a nerve anywhere near the place you experience the twitch.

Causes are also only loosely understood; there are certain behaviors that can trigg ...

I'm not sure whether it's his voice or whether it is the meaning behind the script, nevertheless this is awesome.

This is supernova remnant W49B. It is located about 26,000 light-years from Earth, and as we see it it is approximately 1,000 years old. Compared to other supernova remnants of similar type and age, it is distorted in an usual way. Astronomers believe that it is distorted because it is in the infant stages of of forming a black hole -- the very first time this has been observed.

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.

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. ...

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. ...
