Engineers have successfully transferred digitally encoded information wirelessly using nuclear radiation instead of conventional technology. Radio waves and mobile phone signals rely on electromagnetic radiation for communication but in a new development, engineers from Lancaster University in the UK, working with the Jožef Stefan Institute in Slovenia, transferred digitally encoded information using “fast neutrons” instead. The researchers measured the spontaneous emission of fast neutrons from californium-252, a radioactive isotope produced in nuclear reactors. Modulated emissions were measured using a detector and recorded on a laptop. Several examples of information, i.e., a word, the alphabet, and a random number selected blindly,...

... [E]ven the brainiest sometimes need a lesson in common sense. That’s exactly what the bursar at St. John’s College—the most richly endowed college at Oxford—delivered when he responded to students occupying his 15th-century quadrangle and refusing to leave until the college divested its oil-company shares. The students want the college to sell the more than $10 million of its endowment now invested in Shell and BP, and they want it now. The Times of London reports that bursar Andrew Parker made them a counteroffer. “I am not able to arrange any divestment at short notice,” he wrote. “But I...
