A photo of a specimen of tungsten-fibre-reinforced tungsten after a stress test won the first prize in science publisher Elsevier's "NuMart Image Competition". Johann Riesch and colleagues at the Max Planck Institute for Plasma Physics (IPP) developed the composite material as part of the search for materials that could be used at high-stress locations in fusion plasma vessels.

Although tungsten is the metal with the highest melting point, it is highly brittle and develops cracks under punctual stresses. Taking their cue from fibre-reinforced ceramics, Riesch and his team developed tungsten-fibre-reinforced tungsten where tungsten fibres with a diameter of 150 micrometres bridge the cracks in the tungsten matrix.

The photo taken by Martin Balden shows the new material after a breaking test as seen by an electron-microscope, demonstrating how the fibres enhance the fracture toughness of the tungsten material. The image will feature on the cover of the jubilee issue of Elsevier's Journal of Nuclear Materials, which will be published in April 2019, marking its 60th anniversary.

The sequel of the ITER manga is out. Taiyô Tenno, the young Japanese art student who had visited Provence and had been introduced to ITER by French scientist Soléane, has returned to France. He spends his summer vacation as an intern at ITER's Communication Department where he and his two intern colleagues are tasked to come up with an idea of how to reach out to people all over the world and spread the word about ITER.

Taiyô meets Soléane again who introduces him to ITER's Deputy-Director Eisuke Tada. During a weekend walk on the Sainte Victoire mountain near Aix-en-Provence with Mr. Tada, Taiyô learns about the diversity at ITER, with experts coming from all over the world, sharing ideas in an open and frank atmosphere. Taiyô is inspired and returns to work full of ideas.

To find out how the story ends, read the new installment "A small sun on Earth. Volume 2: Internship chapter" published by ITER Japan. It is available in Japanese, English and French.
