A Dancer, dressed with the traditional Yi costume, waits to perform at the Torch Festival, in Xichang, China's Sichuan province on July 27, 2016. As a result of fast urbanisation in the rural area of China Like Lienchang prefecture, the traditional costume is fading away for the Yi people in daily life. (Photo by Fred Dufour/AFP Photo)

Have you ever heard of a phenomenon called the Uncanny Valley? Illustrations created by Swiss illustrator Christo Dagorov show how horrible something may look when it’s a hair’s breadth away from looking human. In his illustrations he combined the shape of human lips with trees, buildings, and even human bodies, making it look from a distance as if the lips were horribly deformed by some unknown disease. However, after a while you make out the shapes, yet the feeling of uneasiness remains, making you shiver from unsuppressable disgust. (Photo by Christo Dagorov)

A cenote is a natural phenomenon, a sinkhole in the Earth’s surface. The Yucatan Peninsula in Mexico has an estimated 7,000 cenotes because it is primarily made up of porous limestone. For millions of years, rainfall slowly ate away at the limestone and a huge system of underground caves and caverns was formed. Many filled with water from rain or from the underground water table. When the roof of a water filled cave collapses, a cenote is born. The water found in a cenote may be fresh water, salt water, or both. Structurally it may be completely open, like a lake, almost completely closed with just a small opening at the top, or somewhere in between.

Vanessa, thirty-five, had three children with an abusive husband. She “lost her mind, started doing heroin”, after losing the children, who were taken away and given to her mother. The drugs led to homelessness and prostitution. She grew up on Arthur Avenue in the Bronx, but now spends her time in Hunts Point, “trying to survive everyday. Just doing whatever it takes”.

In this artist's impression supplied by the ESO (European Southern Observatory) on April 25, 2007, the planetary system around the red dwarf, Gliese 581, is pictured showing what astronomers believe is the most earth like planet found outside our solar system to date. Using the ESO 3.6-m telescope in Chile, astronomers have uncovered the planet which could have water running on its surface. The planet orbits the faint star Gliese 581, which is 20.5 light-years away in the constellation Libra. (Photo by ESO via Getty Images)

Five-year-old Julian Becker and his 165 pound pet Newfoundland Max have been best buds around all their lives. To commemorate the friendship and to keep Julian's father, a Naval officer who is often away, in the loop, Julian's mom Stasha began taking photos. Photo: Hats off (or on) to Julian for sharing his blanket with his good buddy. Not that the furry beast needs it... (Photo by Stasha Becker/Rex Features)
