These picture look like an artist has painted abstract patterns on canvas – but in fact they are natural rivers captured on camera. The spectacular rivers in Iceland's central highlands and southern parts originate from glaciers, which is why the water is a milky colour. They are shallow rivers and the water spreads quickly over a flat and sandy surface, creating random and beautiful patterns.

Some foods have significantly more Calories than others but what does the difference actually look like. Each of the photographs below represents 200 Calories of the particular type of food; the images are sorted from low to high calorie density. When you consider that an entire plate of broccoli contains the same number of Calories as a small spoonful of peanut butter, you might think twice the next time you decide what to eat. According to the U.S. Department of Agriculture, the average adult needs to consume about 2000 – 2500 Calories to maintain their weight. In other words, you have a fixed amount of Calories to "spend" each day; based on the following pictures, which would you eat?

The ferocity of crises worldwide is forcing a record number of people to flee their homes, seeking some form of safety within their own country or across international borders. There are 65.3 million displaced people worldwide, including 21.3 million refugees. Most have lost their homes to armed conflict or natural disasters but other factors, such as extreme poverty and climate change, also drive displacement. The International Organisation for Migration commissioned photojournalist Muse Mohammed to document the plight of the displaced. (Photo by Muse Mohammed/IOM)

Some people think of trolls as nothing but savage beast, yet others realize that beneath their rock-hard skin hides a gentle kind heart. Ivar Rodningem is one of the people who knows the true nature of trolls. Though these creatures look unruly, it is just the way they were born. Trolls come in all shapes and sizes. Some are small, some are large, and some are simply enormous. They help each other out, though elders tend to be loners, preferring the company of their own thoughts to anybody else. You shouldn’t run for your life if you ever meet a troll, though we wouldn’t recommend pestering them, as they are mighty strong, even the little ones.

A destroyed T-72 tank, which presumably came from Russia, is seen on a battlefield near separatist-controlled Starobesheve, eastern Ukraine, October 2, 2014. The burnt-out remains of dozens of tanks and armoured vehicles in fields near the small village of Horbatenko bear witness to the ferocity of a battle that turned the tide of the conflict in eastern Ukraine. Among the debris, Reuters found the blackened carcasses of what military experts have since identified as two Russian army tanks, supporting statements by Kiev and the West that the rebels were backed by troops and equipment sent by Moscow.
