The attempt went ahead from waters on the western side of Hawaii despite earlier concerns that bad weather could delay the operation. The satellite, known as USA 193, stopped communicating and lost control hours after it was launched in 2006. Officials say the shootdown was approved amid concerns that fuel on board could pose a threat to humans.
John Backus, who died on 17 March, was a pioneer in the early development of computer programming languages, and was subsequently a leading researcher in so-called functional programming. He spent his entire career with IBM.
Fortran remained Backus's lasting contribution to computing, for which he was awarded the National Medal of Science in 1975 and the Turing Award of the Association of Computing Machinery in 1977 — computer science's highest honour.
A tropical ant is the new speed champion in the animal kingdom. According to new research, the trap-jaw ant Odontomachus bauri crashes its mandibles shut at up to 137 kilometers per hour, making its strike the fastest self-powered movement known. The chomp generates so much force that, should the hunter become the hunted, it can also be used to propel the ant out of danger.
