In this second part of the series about ITER (see first here), we start giving a more detailed description of the ITER machine. Then, we address some important challenges that have been identified for each of its parts and scientists’ plans to solve them. Tokamak design After all, the core of a nuclear plant is […]

Strawberry poison frogs pass on chemical defense to offspring Strawberry poison frogs provide chemical defenses to their tadpoles by feeding them eggs spiked with alkaloids. Researchers measured alkaloid content in the frogs during different stages of development, separating them into two groups — one in which tadpoles were reared and fed by their mothers and […]

Researchers try to figure out sea worm’s blue glow Researchers are a step closer to figuring out why a common sea worm glows blue on the shallow seafloors it calls home, thanks to a pair of experiments conducted by biologists at Scripps Institution of Oceanography. First, they found that the worm, unlike other light-emitting organisms […]

China’s Forbidden City had rocks transported via ice sheets. The massive stones used to build parts of China’s Forbidden City in the 15th century were pulled by several hundred workers more than 40 miles on sledges across artificial ice, researchers say. China had discovered the wheel, but a sign at the Forbidden City hinted that […]

Brains wired to be wary of snakes The brain is wired to detect the threat of snakes, according to a study published in the Proceedings of the National Academy of Sciences. Researchers studied a pair of macaque monkeys born in captivity who had not encountered snakes before the experiment. When shown an image of a […]

Cassini images add clues to Titan’s weather cycle New photos from NASA’s Cassini spacecraft are giving researchers clues to the weather cycle of Titan, one of Saturn’s moons. By studying previous images, scientists think Titan has a hydrologic cycle, in which hydrocarbons rain onto the surface filling the lakes and then evaporating back into the […]

Natural non-wetting structures, particularly lotus leaves (Fig. 1a), have inspired the development of synthetic liquid-repellent surfaces. These surfaces rely on the formation of a stable air–liquid interface, but present limited repellency to oils with high contact angle hysteresis, failure under pressure and inability to self-heal. The paper by Wong et al. presents a novel approach […]

The way in which nature manages to create functional diversity in matter is probably the wisest guide for biomaterials engineers, who are always looking for new creative processes to come up with new materials. The conventional way of designing complex materials with new functionalities is explained by the so-called top-down approach , in which a […]

How science goes wrong Scientific research has changed the world. Now it needs to change itself The Economist Astronomers find a “tilted” solar system Scientists have discovered a “tilted” solar system, according to a report in Science. While looking at Kepler-56, a star about 2,800 light-years away, they were surprised to find that the plane […]

Nobel-laureate Pierre-Gilles de Gennes allegedly once said of nuclear fusion: “We say that we will put the sun into a box. The idea is pretty. The problem is, we don’t know how to make the box “. Indeed, the task is challenging in a way that even surpasses the stringent design of world-famous LHC (Large […]
