Textbook illustrations and museum dioramas could soon be even more accurate in their depiction of the rich colours of long-extinct animals like dinosaurs. An international team of scientists used advanced X-ray imaging techniques to map out elements related to pigmentation in modern birds of prey, which they will use to reconstruct the likely colour patterns of fossil specimens.

In order to CT scan a horse, the 450kg animal has to be anaesthetised and carefully manoeuvred into a machine. The procedure is even more difficult than it sounds. A newly developed technique uses a pair of precisely-controlled robots to perform the scan, so that the animal can be awake and standing up while it's being imaged.

The vibrant colours of many of Vincent van Gogh's most famous paintings — including his Sunflower series — have been fading over the last 100 years. Now a team of Italian scientists has come up with an explanation as to why the lead chromate dyes favoured by the artist when mixing his pigments degrade so much under light. They described their work in a new paper in Chemical Science.

I just knew about They Ate WHAT? A competition where vets send X-rays of animals with weird things stuck within their bodies. These are some of the winners — some images look kind of harsh but don't worry, all the animals were treated appropriately and they are fine and hungry again.

Aussie Photographer Brendan Fitzpatrick uses both chest X-ray and mammogram machines in his photography, a technique he learned when he had to develop an X-ray like look for a client — it turned out the best way was to use actual X-rays. He told us about his work.

It's no surprise that the diamond industry is willing to spend whatever it takes to make the process of mining precious gems even more profitable. And while it already relies on X-ray technology for spotting diamonds on the surface of mined ore, researchers at the Fraunhofer Institute's Development Center for X-ray Technology EZRT have developed a way to now spot them buried inside rocks.
