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.

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 ...

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. ...

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. ...

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.

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.

A miniture fox, the fennec fox
|
view preview
This fantastic minifox is a desert dweller who weighs in around 3 lb. (1.4 kg) and stretches just beyond a foot (30 cm), not counting its uniquely gigantic ears, which can measure almost half its body length. The smallest of all the world\'s foxes, the fennec burrows away during the day and scavenges for insects and fruit at night. Its huge ears emit body heat and help it keep cool among the dunes of the Sahara and elsewhere in North Africa. Some locals hunt the fennec for its fur, while others capitalize on its cuteness in the pet trade. ...

Tips to keeping your teeth white
|
view preview
Whitening treatments do not permanently whiten teeth. If you expose your teeth to foods and beverages that cause staining you may see the whiteness start to fade in as little as one month after treatment. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed. You worked hard to get your teeth white. Here are some tips to help maintain your pearly whites. - Avoid the consumption of or exposure to products that stain your teeth, such as coffee, tea, and red wine. If you do choose to consume beverages that stain, consider using a straw so that the liquid bypasses your front teeth.
- Brush or rinse immediately after consuming stain-causing beverages or foods.

The infant stages of of forming a black hole

view preview
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.

Turn the taste of sour to sweet with these natural tablets
|
view preview
By themselves, miracle berries do not taste like much. The reason to eat them is that they contain a chemical called miraculin that binds to the sweet taste receptors on your tongue, changing their shape and making them respond to sour and acidic foods. The upshot of this effect is that some things you eat taste spectacularly different. Straight Tabasco sauce tastes like donut glaze. Guinness tastes like a chocolate malt. Goat cheese tastes like cheesecake. After about an hour of craziness, your taste buds go back to normal, no harm done. ...

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. ...

Aerogel
|
view preview
Also known as frozen smoke, Aerogel is the world's lowest density solid, clocking in at 96% air. It is basically just a gel made from silicon, except all the liquid has been taken out and replaced with gas instead. If you hold a small piece in your hand, it is practically impossible to either see or feel, but if you poke it, it is like styrofoam. Aerogel is also quite useful. It supports up to 4,000 times its own weight and can apparently withstand a direct blast from two pounds of dynamite. It is also the best insulator in existence, which is why we do not have Aerogel jackets: it works so well that people were complaining about overheating on Mount Everest. ...

Why is my eyelid twitching?
|
view preview
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 ...

A baby macaw

Here are some adorable images of macaw parrot chicks getting weighed and measured. The one on the left is just one week old, and the one on the right is seven weeks old. Researchers at the Tambopata Research Center have been studying the wild macaw populations for years and tracking the growth of the nestlings. By climbing up into the trees and gathering data on these macaws, the researchers are able to do a lot of interesting science and gather information critical to protecting these species. ...

Mount Fuji with a hat
|
view preview
This is an example of a lenticular cloud, also known as altocumulus standing lenticularis. These are stationary, lens-shaped clouds that are formed at high altitudes. They are included in the middle layer cloud family because the bases of the clouds are stationed between about 2,000 and 7,000 meters. These clouds form when moist air is forced to flow up around mountains and large hills. The water is super cooled and condensed from air below the dew point temperature.
