What you're looking at above is a confluence, and in geography, this refers is the meeting of two or more bodies of water. It's either the point where a tributary joins a larger river, called the main stem, or where two streams meet to become the source of a river of a new name, such as the confluence of the Monongahela and Allegheny rivers in Pittsburgh, Pennsylvania creating the Ohio River.

A light pillar is basically a visual phenomenon created by the reflection of light from ice crystals with near horizontal parallel planar surfaces. The light can come from the Sun (usually at or low to the horizon) in which case the phenomenon is called a sun pillar or solar pillar. Continue reading for five more incredible facts you may not have known about this natural phenomenon.

Here's what creator Mark Phillips and his Arizona-based company, Lipsmark, LLC, has to say about Palcohol: "It varies per version but basically, alcohol [...] and in the cocktail versions, natural flavorings and Sucralose as a sweetener. The ingredients of each version are listed on the front of the package. Palcohol is gluten free." The company says that adding five ounces of liquid to a packet of Palcohol would be "equal to a standard mixed drink." Continue reading for the news report and more information.

A sun dog is basically an atmospheric phenomenon that creates bright spots of light in the sky, often on a luminous ring or halo on either side of the sun. They may appear as a colored patch of light to the left or right of the sun, 22° distant and at the same distance above the horizon as the sun, and in ice halos. They can be seen anywhere in the world during any season, but they are not always obvious or bright. Sundogs are best seen and are most conspicuous when the sun is low.

Scientists have successfully cloned the first human embryo from adult cells, and this breakthrough could pave the way to personalized organ transplants as well as other regenerative treatments based on stem cells that can be grown into any type of human tissue. Last year, the world's first cloned human embryo was created when a team of scientists used cells from a fetus and an 8-month-old infant. This new experiment involved making a clone embryo from cells taken from adult men, ages 35 and 75, by extracting the nucleus out of a cell and placing it in a donor egg without a nucleus.

Photographer Olivier Grunewald loves exploring of volcanoes, and there was one in particular that caught is eye. So, he set out to Kawah Ijen, a volcano near East Java, Indonesia, that seeming spews a blue liquid. This happens because it constantly leaks sulfurous gases and then condenses into liquid sulfur to create surreal glowing liquid that streams down the sides of the volcano in a spectacle of light. Continue reading for more pictures and information.

In technical terms, an earthquake refers to the sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. The 1960 Chilean Earthquake is the largest earthquake that has been measured on a seismograph, reaching 9.5 magnitude on 22 May 1960. Its epicenter was near Canete, Chile. Continue reading to see what happens to skysrapers during these mega quakes.

The Venezuelan Poodle Moth is a possible new species of moth discovered in 2009 by Dr. Arthur Anker of Bishkek, Kyrgyzstan, in the Gran Sabana region of Venezuela. It bears similarities to the Diaphora mendica, the Muslin Moth, but most likely belongs to the lepidopteran genus Artace. Continue reading for two videos and more information.

Researchers at MIT, lead by Yichen, have developed a mind-bending vanishing mirror that turns into a window, solveing the problem of photographing things at odd angles, using a structure made of 84 ultrathin layers that alternate between ordinary glass and tantalum oxide. That's right, "as light passes from one of these layers to the next, some gets partially reflected - except for light that approaches from a certain angle. Any light that hits the surface of a layer at this so-called Brewster angle, and with a particular polarisation, will pass straight through as if the surface wasn't there. The Brewster angle is different for each pair of materials as it depends on their refractive indices," according to New Scientist. Continue reading for a video and more information.

Don't you just coming up to a traffic light only for it to have just turned yellow? You can take out the guesswork with the hourglass LED design you see above. Simply put, all drivers will know exactly how much time they have until the next light, complete with countdown meter. We've rounded up three of the coolest traffic light designs of the future for your viewing enjoyment. Continue reading to see them all.
