Scientists develop an β€˜electronic skin’ that can mimic the natural functions of human skin (3 minute read)

Electronic skin (e-skin) could play an important role in next-generation personalized medicine, prosthetics, AI, and soft robotics. The ideal e-skin would mimic the natural functions of human skin, such as sensing and touch, while being flexible and durable. A team of scientists has developed a durable e-skin using a hydrogel reinforced with silica nanoparticles and a 2D titanium carbine MXene sensing layer bound together with highly conductive nanowires. The e-skin's conductive pathways to the sensor layer remain intact even when the material is stretched to 28 times its original size. It can sense objects from 20cm away and respond to stimuli in less than one-tenth of a second.

China's first nuclear reactor using Hualong One tech connected to grid (2 minute read)

Hualong One is one of the world's most advanced nuclear power reactor designs. It was developed in China. The reactor is designed to operate for 60 years, with 177 reactor cores which are replaced every 18 months. It features both active and passive safety features and a double-layer safety shell. The first Hualong One nuclear reactor was successfully connected to the grid in the Fujian Province on Friday. It will undergo various tests before starting commercial operations later this year. The achievement is significant for the country's energy restructuring plan and pursuit of low-carbon development.

WarGames for real: How one 1983 exercise nearly triggered WWIII (23 minute read)

32 years ago, the world was the closest it had ever been to nuclear armageddon. The KGB had constructed software to forecast if the US and its allies were planning a nuclear strike. A war game staged by the US over two weeks in November 1983 triggered the forecast. The procedures and tactics used in the war games were things that the Soviets had never seen, and to the Soviet leadership, it looked like a cover for a genuine surprise attack planned by the US. With many other factors in consideration, the Soviets had good reason to think that the US believed it would win a nuclear war. As the US military increasingly turns to machine learning, the lesson of what can happen when an algorithm gets it wrong should not be forgotten.
