Some bugs, such as water scorpions, long-toed water beetle and predaceous diving beetles (shown below) use the molecular properties of water to create miniature scuba diving tanks and spacesuits. The cohesive forces between water molecules essentially makes water molecules "stick" together, allowing bubbles to form against a wall of tension. These little insects are small enough to take advantage of this, by trapping a bubble in their outer wings or tiny bristles on their shell.

Someone who greatly enjoys sweet foods is said to have a "sweet tooth." Experimental evidence now shows us that eating sweets forms memories that may control eating habits. In other words, people may enjoy eating sweets because the taste is correlated with positive memories.

The findings, published online in the journal Hippocampus, show that neurons in the dorsal hippocampus, the part of the brain that is critical for episodic memory, are activated by consuming sweets. Episodic memory is the memory of autobiographical events experienced at a particular time and place.

In the study, a meal consisting of a sweetened solution, either sucrose or saccharin, significantly increased the expression of the synaptic plasticity marker called activity ...

Black panthers do have spots. By using an infrared camera, scientists have been able to see the hidden patterns for the first time in wild Malaysian panthers.

One of the driest places on Earth, the Atacama Desert in Chile - has become covered in a carpet of flowers, thanks to a year of extreme rainfall brought on by El Niño. El Niño is the abnormal warming of waters in the eastern Pacific Ocean around the equator.

The world's worst pain comes from bullet ant venom (shown above). According to Wikipedia, the pain caused by this insect's sting is purported to be greater than that of any other hymenopteran, and is ranked as the most painful according to the Schmidt sting pain index, given a '4+" rating, above the tarantula hawk wasp and, according to some victims, equal to being shot, hence the name of the insect. It is described as causing "waves of burning, throbbing, all-consuming pain that continues unabated for up to 24 hours'. The pain is immediate and unlike even the worst physical injuries where your brain eventually has enough of it and blocks out the signal from the offending body part, it does not let go for a good long while.

Watch the video above, the trick is nothing short of incredible!

This is due to a mechanism called the opponent-process theory, which was developed in the 1870s. It is the idea of perceiving color in terms of paired opposites such as red with green, and yellow with blue. The possible scientific explanation for this theory is that bipolar cells are excited by one set of wavelengths and inhibited by other, which are in extend attached to the cone retinal receptors.

The blue-capped cordon-bleu (Uraeginthus cyanocephalus) has a special talent. Not only can it sing, it can shake a leg or two. For its courtship display, it holds a piece of nesting material in its beak, points its head upward, moves up and down, and sings. Both males and females bob and sing like this, and choose their partner. Now, researchers have found that as the bird bobs, it does a quick tap dance where it stomps its feet.
