Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

Scientists from the University of East Anglia are studying the potential health benefits of dark chocolate, and need 40 female volunteers who would like to eat chocolate every day for a year. The chocolate loving 40 must be post-menopausal and have type 2 diabetes so it can be determined if the flavonoid compounds in chocolate can reduce the risk of heart disease. Dr Peter Curtis, of the UEA's School of Medicine, said, "Our first volunteers are about to return for their final visit to see if the markers of heart health - such as blood pressure and cholesterol levels — have changed. A successful outcome could be the first step in developing new ways to improve the lives of people at increased risk of heart disease."
