The carcass of a yacare caiman lies in the dried-up river bed of the Pilcomayo river in Boqueron, Paraguay, August 14, 2016. In Paraguay, alongside the Pilcomayo River, black vultures flew over a shrinking pond where a group of crocodilian reptiles known as yacare caimans sought refuge. Water from the river, which divides Paraguay and Argentina in the area of the Gran Chaco, was scarce. This is not an uncommon sight in the region of General Diaz, about 700 kilometres (435 miles) northwest of the country's capital Asuncion, where the Pilcomayo's waters form lakes and streams that give life to capybaras, birds and caimans.

A disabled child is buried up to his neck in sand during the partial solar eclipse in belief its rays can heal, in Karachi, Pakistan, 25 October 202. A partial solar eclipse occurs when a portion of the Earth is engulfed by the shadow (penumbra) cast by the Moon as it passes between our planet and the Sun in imperfect alignment. During this eclipse - the first of the decade – the Moon appears to cover the Sun, leaving the Sun's halo as a visible rim forming an annulus, popularly known as the 'ring of fire.

In the remote Argentine Pampas you can find an incredible forest formed in the shape of a guitar. More than 35 years ago, Pedro Ureta unexpectedly lost his wife to a brain aneurysm. Devastated by the loss of his love, he decided to create a shrine to her memory in their field that could only be seen above-head from an airplane. Ureta chose a guitar because it was his late wife’s most loved instrument.

Born in 1958 in Kiev, Ukraine, artist Mark Khaisman studied Art and Architecture at the Moscow Architectural Institute in Russia. Now living in Philadelphia, USA, Khaisman uses rolls of brown packaging tape to create incredible works of art. Mark characterizes his work as ‘pictorial illusions formed by light and shadow’. The three key elements are: translucent packing tape, clear acrylic or film panels, and light. By superimposing layers of packaging tape Mark can ‘play on degrees of opacity that produces transparencies highlighted by the color, shading, and embossment’.
