New "Circuit Breaker" Imposed To Stop Market Crash 460

Lucas123 writes "The SEC and national securities exchanges announced a new rule that would help curb market volatility and help to prevent 'flash crashes' like the one that took place on May 6, when the Dow dropped almost 1,000 points in a half hour. That crash was blamed in part on automated trading systems, which process buy and sell orders in milliseconds. The new rule would pause trading on individual stocks that fluctuate up or down 10% in a five-minute period. 'I believe that circuit breakers for individual securities across the exchanges would help to limit significant volatility,' the SEC's chairman said. 'They would also increase market transparency, bolster investor protection, and bring uniformity to decisions regarding trading halts in individual securities.'"

Quality Open Source Calendaring / Scheduling? 492

Jim R. Wilson writes "In past jobs, I've used Microsoft Outlook/Exchange, Novell Groupwise, and Google Calendar for handling business appointments. I'm sorry to say it, but I have yet to see a rival to Microsoft's scheduling features. On Slashdot I have occasionally read rumblings that there are better open source email and calendaring solutions out there. Can anyone substantiate this claim? What are the OSS alternatives? Can any compete with Microsoft's resource scheduling?"

Data Storing Bacteria Could Last Millennia 252

PetManimal writes "Computerworld has a story about a new technology developed by Keio University researchers that creates artificial bacterial DNA that can carry more than 100 bits of data within the genome sequence. The researchers claimed that they encoded "e= mc2 1905!" on the common soil bacteria, Bacillius subtilis. The bacteria-based data storage method has backup and long-term archival functionality." The researchers say "While the technology would most likely first be used to track medication, it could also be used to store text and images for many millennia, thwarting the longevity issues associated with today's disk and tape storage systems ... The artificial DNA that carries the data to be preserved makes multiple copies of the DNA and inserts the original as well as identical copies into the bacterial genome sequence. The multiple copies work as backup files to counteract natural degradation of the preserved data, according to the newswire. Bacteria have particularly compact DNA, which is passed down from generation to generation. The information stored in that DNA can also be passed on for long-term preservation of large data files."

Huge Reservoir Discovered Beneath Asia 273

anthemaniac writes "Seismic observations reveal a huge reservoir of water in Earth's mantle beneath Asia. It's actually rock saturated with water, but it's an ocean's worth of water ... as much as is in the whole Arctic Ocean. How did it get there? A slab of water-laden crust sank, and the water evaporated out when it was heated, and then it was trapped, the thinking goes. The discovery fits neatly with the region's heavy seismic activity and fits neatly with the idea that the planet's moving crustal plates are lubricated with water."
