A photographer has created a series of paw-traits of hungry dogs pulling hilarious faces as they try and catch treats. Using a unique technique, the shots are captured at the exact moment the adorable pooches attempt to catch an airborne piece of food. The dogs appear surprised, happy, sad, confused – and sometimes even so blasé they miss the treat entirely. The images were taken by Christian Vieler, a photographer from Waltrop, Germany. Here: A labrador retriever. (Photo by Christian Vieler/Caters News)

Vietnamese artist Hoang Tien Quyet produces curved paper forms using a difficult technique known as wet-folding. This adds an element of sculpture to the work, making Hoàng’s origami animals truly remarkable. Too little water and the paper dries before the folding is done; too much water, and the paper will rip.

IT'S a relatively simple idea – set up a mirror so you can capture the reflection of a dramatic landscape in a single photograph. Photographer Daniel Kukla, from New York, created a spectacular series of artworks called The Edge Effect using the technique. He clamped the mirror onto an easel and placed it in various settings in the Joshua Tree National Park, California.

Thierry Duval was born in Paris, France in 1968. His watercolors are characterized by a strong light and precision in drawing, being almost or hiperrealist in the results mainly in his Paris watercolors.

Brain-on-a-chip. Dazzling in green and magenta this image shows the nerve fibres (in green) produced by neural stem cells (in magenta) as they grow on a synthetic gel. Captured by a technique known as confocal microscopy, the image is part of research shedding light on how tinkering with the environment can affect the way in which nerve fibres grow.
