This is the regal ringneck snake (Diadophis punctatus regalis), a subspecies of ringneck snake endemic to the southwestern United States and northern Mexico.

Unlike other subspecies of ringneck snakes, the regal ringneck is almost exclusively ophiophagous, meaning that it has a diet that consists almost entirely of other snakes.

They have a weak venom that serves to immobilize their small prey, but is harmless to humans.

Check out this amazing image of am urodid moth cocoon. According to entomologist and Amazon explorer Phil Torres, It has a really beautiful woven lattice structure that hangs about a foot below a leaf on a thin silk string.

This is an unusual structure because the pupa, resting inside the cocoon, seems fairly exposed to the elements. The hanging likely helps to prevent predation from ants, and the bright orange color may serve as an aposematic signal to predators to prevent it from getting eaten. The tube part at the bottom is the 'escape hatch' from which it eventually will exit as an adult moth. There is not a lot of research that has been done on the evolutionary origin structure - this is one of the many mysteries of the Amazon you can c ...

The Yellow Pages use no virgin paper in the production of their directories, but to produce and deliver 540 million a year requires immense amounts of water and uses immense amounts of energy and fuel. If you need the Yellow Pages, keep it! But if you are among the 70% polled who say they never even open them, opt out. It is just a waste not to.

These amazing images of animals in the womb were compiled by scientists using ultrasound scans and computer graphics.

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. ...

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 ...

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. ...
