From Now I Know: “After the Manhattan Project came to a close, nuclear weapons testing continued for decades. In 1957, the government detonated 29 bombs in the Nevada desert as part of Operation Plumbbob, hoping to develop better weapons. The researchers dug a 500 foot deep hole, dropped the bomb to the bottom, and blew it up, but the bomb yield was much greater than anticipated – 50,000 times greater. Fire shot hundreds of feet into the air from the mouth of the uncapped shaft. So a one ton iron lid was placed at the top of the shaft in hopes of keeping any flames underground. When the bomb went off, it shot the manhole cover skyward, at incredible speeds. How fast? Dr. Robert Brownlee estimated that the manhole cover was traveling at a speed of at least 125,000 miles per hour, making it easily the fastest-moving object in history.”
Severe autism can be permanently reversed, groundbreaking new study suggests

From The Telegraph: “Severe autism can be reversed and symptoms reduced to an indistinguishable level, scientists have discovered. Two non-identical twin girls in the US were found to have a level of autism at 20 months old that required very substantial support. A groundbreaking trial saw their parents and a team of medical experts create a bespoke two-year programme of interventions designed to help the children thrive and flourish as much as possible. Scientists say the programme was successful, with both girls undergoing dramatic improvements in the severity of their symptoms. The progress of one of the girls, described only as Twin P, was heralded as “a kind of miracle” by one of the paediatricians. “One of the twins’ symptoms were reversed to the point of being indistinguishable from children who had never had a history of autism symptoms,” said Dr Chris D’Adamo from the University of Maryland.
