Plaster cast moulds of victims of the Mount Vesuvius eruption lie on a display table in a laboratory at Pompeii October 13, 2015. An expert team made up of archaeologists, radiologists, orthodontists and anthropologists began on September 2015 to use CAT scan technology (computerised axial tomography) to peer inside the plaster cast moulds of Pompeii's victims, in a study that has added more detail to previous findings. A 16-layer scan had to be used in order to penetrate the hardened plaster but the results showed up impressive skeletal remains and near perfect teeth. (Photo by Alessandro Bianchi/Reuters)

An internally displaced woman collects water from a pond to construct a mud-house at the Aboushok camp in El Fasher, North Darfur, Sudan, November 17, 2015.

But it hasn't stopped displaced youngsters, some of whom have spent their entire lives in refugee camps, from dreaming big. Twelve children aged 12 explain their hopes and dreams for the future; ambitions include becoming a doctor, an engineer and a teacher. (Photo by Mohamed Nureldin Abdallah/Reuters)

A photographer is using a unique method to show the shift from day to night across famous cities in spectacular images. Daniel Marker-Moors' take on time-lapse photography – which he calls time slice – sees the photographer snap image after image, before combining them to create beautiful, vibrant works. His images usually focus on a point in the day with the most dramatic change in light, such as sunrise or sunset. Marker-Moors, from Los Angeles, begins by shooting hundreds and sometimes thousands of images from the same spot. Here: Chicago – 35 photographs, 15 minutes.

There are many ways to interpret the creations of Yoshitoshi Kanemaki, whose works usually involve sculptures of people where two or more characters have merged into a single being. Possibly, Yoshitoshi Kanemaki is trying to express through his sculptures that everyone’s soul is multifaceted. Good emotions are mixed with the bad, love is mixed with hate, contempt with admiration. How often do you hear that a person loves someone deeply, while doing completely horrendous things, unable to see that he or she is destroying their object of love? Nevertheless, we should be thankful to the nature for all the different emotions that we are able to feel. Unlike animals, who only show simple forms of emotions, such as anger, happiness, and a few others, human soul is much deeper, allowing us to feel a full plethora of emotions.

If we were to burn NH4Cr2O7 with HgSCN in the Dark Ages in Europe and show it to anyone, it is us who would be burning next on a fiery cross of Inquisition. And it’s no wonder, since this experiment produces a truly marvelous result. At first, as you ignite the mixture of NH4Cr2O7 and HgSCN, all you can see is that it is slowly burning with a reddish flame. After a while, however, a crater is formed in the middle of the burning pile, and then, suddenly, tentacle-like appendages start sprouting from the burning mixture. And you can almost hear the scream of the mad occultist – “Come forth, Kraken! Come forth!” But of course, this is simply a chemical reaction that is called the "Pharoah's Serpent". It was also often sold in firework stores until people realized that it was toxic.

This is the remarkable moment a group of skydivers performed a world record breaking feat in honour of their friend who died while skydiving. Known as a “Bigway”, the daring jump involves 57 people holding hands in a predetermined design as they hurtle towards the ground, head first. After making the first shape, the group then break away before coming back together to form a second shape all in a single skydive. Captured using a GoPro camera by Alaskan skydiver, Ben Nelson, 36, the topsy-turvy footage shows the adrenalin junkies soaring through the air at around 160mph before banding together twice in mid-air, making the stunt a world first.

A protester throws a stone towards a burning police bus in front of him, during clashes with police, in central Kiev, Ukraine, Sunday, January 19, 2014. Hundreds of protesters on Sunday clashed with riot police in the center of the Ukrainian capital, after the passage of harsh anti-protest legislation last week seen as part of attempts to quash anti-government demonstrations. The violent scenes further escalated this ex-Soviet republic's political crisis and showed a rift among opposition leaders, one of whom fought bravely to stop the violence, while others condemned the events from afar.
