“Former Harry Potter star Emma Watson has shed her squeak-clean image by parading the streets in a bra and hot pants for her role in Sofia Coppola's latest movie. The actress has signed up for a leading role in The Bling Ring, playing one of the real-life teens who stole from the homes of stars including Paris Hilton, Lindsay Lohan and Orlando Bloom in 2008 and 2009. A series of images from the Los Angeles film set are set to shock the Brit's younger fans as she has been photographed strutting in tiny shorts, a bra-style top, leather jacket and towering high heels”.

This green-skinned trio were happy to pose for the camera – with one little frog smiling happily for its close up. The three Reinwardt's Flying Frog, commonly known as the black webbed tree frog or the green flying frog, were spotted playing in a tree by photographer Hendy Mp. The 25-year-old who saw the frogs near his home in Sambas, Kalimantan Barat, in Indonesia, said they reminded him of three brothers playing together. (Photo by Hendy Mp/SOLENT News)

Painted eggshell displayed at Wayan Sadra's workshop on April 14, 2014 in Sukawati, Gianyar, Bali, Indonesia. 50-year-old Wayan Sadra got the idea to start his eggshell painting business, after his niece who worked in a five star hotel asked for his help to paint on an egg for an Easter egg competition. Now the business he started in 1997 attracts customers for his painted eggs from Germany, France, Italy, and the Netherlands. Sadra usually experiences a surge in sales ahead of Easter.

In 2002 photographer Corey Arnold left behind a poor economy in San Francisco and headed up to Alaska to try his luck at his longtime passion of fishing. Arnold, who had worked summers during college on a salmon boat in Alaska, signed onto the f/v Rollo, a crabbing boat that fishes in the dangerous Bering Sea. While working long, strenuous hours on the Rollo, Arnold often stole away with the captain’s permission to grab his camera and photograph the crew and the ship. Arnold eventually put together “Fish Work: Bering Sea”, a documentation of his seven adventurous and dicey crab seasons aboard the Rollo. (Photo by Corey Arnold)

“Rudolf Khametovich Nureyev was a Russian Tatar dancer from the former Soviet Union, primarily known for his work in ballet. Nureyev's artistic skills explored expressive areas of the dance, providing a new role to the male ballet dancer who once served only as support to the women. He defected to the West, despite KGB efforts to stop him. According to KGB archives studied by Peter Watson, Nikita Khrushchev personally signed an order to have Nureyev killed”.

“Inspired by the French authorities' solution to move Romas from point A to point B, Romanian authorities planned and started forced evictions of Roma informal settlements in cities like Cluj-Napoca and Baia Mare. Some of these settlements date back to the early 1990’s. These communities were tolerated by the authorities who verbally encouraged Romas to build in the area, meanwhile, reassuring them nothing bad would ever happen to them. However, the the reality today is that during political campaigns, authorities are planning forced evictions without reasons other than ethnic cleansing of the cities. My home documents the every day life of Roma communities in Romania, 2011”. – Mugur Varzariu. (Photo by Mugur Varzariu, 2011 FotoVisura Grant Finalist)

The winners of The London’s Natural History Museum's prestigious Wildlife Photographer of the Year for 2013 have finally been unveiled. Selected from almost 43,000 entries from 96 countries, the winners offer a glimpse of the stunning array of natural beauty on our planet. Photo: Canada: “Lucky pounce”. “Anticipating the pounce – that was the hardest part”, says Connor, who had come to Yellowstone National Park, Wyoming, USA, in search of wildlife as much as the spectacular landscape. He had found this fox, his first ever, on his last day in the park. It was so absorbed in hunting that Connor had plenty of time to get out of the car and settle behind a rock. It quartered the grassland, back and forth, and then started staring intently at a patch of ground, giving Connor just enough warning of the action to come. When it sprung up, Connor got his shot. And when it landed, the fox got his mouse. (Photo by Connor Stefanison/Wildlife Photographer of the Year 2013)

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.
