Earth May Harbor a Shadow Biosphere of Alien Life 267

An anonymous reader sends us to Cosmos Magazine for a speculative article arguing that a 'shadow biosphere' may exist on Earth, unrelated to life as we know it. If such non-carbon-based life were found here at home, it would alter the odds for how common life is elsewhere in the universe, astrobiologists say. "The tools and experiments researchers use to look for new forms of life — such as those on missions to Mars — would not detect biochemistries different from our own, making it easy for scientists to miss alien life, even if [it] was under their noses. ... Scientists are looking in places where life isn't expected — for example, in areas of extreme heat, cold, salt, radiation, dryness, or contaminated streams and rivers. [One researcher] is particularly interested in places that are heavily contaminated with arsenic, which, he suggests, might support forms of life that use arsenic the way life as we know it uses phosphorus."

So you not only use MS products but you don't bother updating your lectures either? Congratulations.

Apple Delays Leopard to October 545

SuperMog2002 writes "Apple Insider has the sad news that Mac OS X Leopard has been delayed until October. Apparantly software engineers and QA had to be reassigned to the iPhone in order to get it out on time, costing Leopard its release at WWDC. For now the original press release from Apple can be found on the 'Hot News' part of their site, though Apple did not provide a permanent link to the story. 'While Leopard's features will be complete by June, the Cupertino-based company said it cannot deliver the quality release expected by its customers within that time. Apple now plans to show its developers a near final version of Leopard at the conference, give them a beta copy to take home so they can do their final testing, and ship the software in October.'"

RIM Strikes Back, Files Countersuit Against Visto 83

SilentOne writes "Research In Motion Ltd. launched an all-out assault on competitors yesterday, countersuing its latest legal nemesis and introducing software to pre-empt imminent launches by other challengers. The countersuit also gives RIM a chance to move the patent battle to a courtroom where it has a better chance of beating Visto. Visto filed suit against RIM on Monday in the U.S. District Court for the Eastern District of Texas, Marshall Division, which reportedly favours patent holders in 92% of cases heard by the court. Jim Balsillie, RIM's co-chief executive, said the company wants the trial moved to the Dallas area, where RIM's U.S. headquarters are located, for practical reasons. Meanwhile, RIM is giving away a free software package, valued at US$3,000, to hook the e-mail accounts of small businesses and consumers up to BlackBerries instead of competitive devices from Palm and Microsoft."
