Two workers shovel mud from the river as they look for gold on March 25, 2014 in Lampang, Thailand. Thai villagers from Wang Nuea, North of Thailand, look for gold in the river every year during the drought season. They are able to make an average around USD 15 per day, however two years ago they reached USD 200 in one day due to the river level dropping so much. The workers begin to search for gold at 10 AM and work until sunset, often working second jobs in the day in order to survive. (Photo by Borja Sanchez-Trillo/Getty Images)

“Jacob «Jack» Kevorkian (May 26, 1928 – June 3, 2011), commonly known as “Dr. Death”, was an American pathologist, euthanasia activist, painter, composer and instrumentalist. He is best known for publicly championing a terminal patient's right to die via physician-assisted suicide; he said he assisted at least 130 patients to that end. He famously said, «dying is not a crime»”. – Wikipedia

Highly commended birds : Crested guan by Tim Hunt (UK). ‘This photo shows a crested guan in the cloud forests of Costa Rica as it pauses while foraging on a lone branch. Due to the clouds that are so typical for this habitat, I could often only photograph the bird’s silhouette against a grey sky. But then, for a short moment only, the sun broke through the clouds, and I overexposed the image by over two stops in order to blow out the background and allow this beautifully marked bird to stand out’.
