Coloured X-ray of a barn owl. A physicist has used X-ray to create an extraordinary collection of artwork. Arie van't Riets pictures reveal birds, fish, monkeys and flowers in an incredible new light. The 66-year-old, from Bathmen in the Netherlands, began X-raying flowers as a means to teach radiographers and physicians how the machine worked. But after adding a bit of colour to the pictures, the retired medical physicist realised the potential for an exciting new collection of art. (Photo by Arie van't Riet/Barcroft Media)

Denis and Nelya, both 30, from Moscow, Russia invited brown bear Stepan along to their very special ceremony. As well as witnessing the couple exchange vows, the bear also played the role of registrar at one point. Denis said: “We both knew Stepan is a very kind bear but still it is a huge, unpredictable animal so we were a bit scared, but still happy to be able to make our dream come true. It was a fantastic experience to have this photoshoot with Stepan”. (Photo by Olga Barantseva/Caters News)

A buffalo was on the verge of becoming dinner for a pride of lions… before his best friend stepped in. Usually, this kind of scene in South Africa ends with a tasty buffalo steak for the lions, but not this time. Just when an attacking lion thought he had the upper-hand, he got a bit of a (hilarious) surprise.

Cool rider Ace on the back on the motorbike, on January 12, 2015, in Surabaya, Indonesia. A pair of dogs enjoy a bit of bark-and-ride – as they weave through Indonesiaís traffic on the back of a motorcycle. Wearing red-framed sunglasses and a helmet the two golden retrievers happily sandwich their owner on the fast bike. Unsurprisingly, the sight of the docile dogs hitching a fast ride in Surabaya, Indonesia, attracts a lot of attention from onlookers. Ace and Armani have been riding since they were just a few months old and now at the age of three the pair jump onto the bike whenever they think their owner is heading out.

In the past people used to bury their loved ones or turn them into ashes. However, now there is a completely new possibility. Since having an urn with ashes in your house may be a bit weird, you may want to choose the option of turning your deceased relative into a diamond. Yes, diamond! You’ve heard us correctly. By using immense heat and pressure, the ashes you get after cremating a person can be turned into a real diamond. After this, the diamond can be left as it is, and stored in a jewelry box, or it can be used as a piece of jewelry, such as a ring or a pendant, allowing you to always keep your loved one close to your heart.
