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. Photographer Andrey Ermolaev from Moscow, Russia, flew 500ft above the unique sight in a small plane. (Photo by Andrey Ermolaev/Solent News)

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)

David Yeo’s photography places naturally small species alongside animals that have been selectively bred to be tiny and cute. Here: “The most difficult aspect of this shoot was to get each African pygmy dormouse – also known as micro squirrels – on to a separate camera. Once in place, they needed to remain still long enough to get them both in the frame and looking at me. Often solitary, they naturally wanted to move away”.

A photographer takes picture of an automotive model during the 36th Bangkok International Motor Show in Bangkok, Thailand, March 24, 2015. No automotive event is complete without the latest offering of high-end cars and motorcycles, and the obligatory accessories stationed at each booth: nubile, young auto-show girls in skimpy, skinsqueezing outfits. This year's Bangkok International Motor Show did not disappoint, attracting a larger horde of eager, flesh-seeking photographers than actual fans of automobiles.

Typhoon Yolanda – also known as Haiyan – struck the central part of the country November 8, 2013, leaving at least 6,300 people dead and over four million displaced. A month after Typhoon Haiyan, the United Nations Population Fund estimates that 5,000 women were subjected to sеxual violence. A study by the Health and Human Rights online publication shows the majority of young girls and women in Manila’s sеx industry come from poverty-stricken areas – such as Leyte, Samar, Cebu and southern Mindanao – and enter trafficking through force, deception, economic desperation and psychological manipulation.
