Cosmic Rays and Global Warming 548

Overly Critical Guy writes "The former editor of New Scientist has written an article in the TimesOnline suggesting that cosmic rays may affect global climate. The author criticizes the UN's recent global warming report, noting several underreported trends it doesn't account for, such as increasing sea-ice in the Southern Ocean. He describes an experiment by Henrik Svensmark showing a relation between atmospheric cloudiness and atomic particles coming in from exploded stars. In the basement of the Danish National Space Center in 2005, Svensmark's team showed that electrons from cosmic rays caused cloud condensation. Svensmark's scenario apparently predicts several unexplained temperature trends from the warmer trend of the 20th century to the temporary drop in the 1970s, attributed to changes in the sun's magnetic field affecting the amount of cosmic rays entering the atmosphere."

Spotlight Improvements In Leopard 356

Mac OS X 10.5 Leopard is set to feature several new enhancements to Spotlight, Apple's desktop search, and ComputerWorld outlines them. The improvements include searching across multiple networked Macs, parental search snooping, server Spotlight indexing, boolean search, better application launching (sorely needed), and quick-look previews.
