Maria Williams writes to tell us about worry surrounding the impending startup of CERN's Large Hadron Collider. Some fear that the device, in creating mini black holes, could jeopardize Life As We Know It. While the tiny black holes should evaporate quickly — throwing off so-called Hawking radiation that can be detected — CERN software developer Ran Livneh reminds us that "Any physicist will tell you that there is no way to prove that generated black holes will decay." The LHC site assures us there's nothing to worry about. The flap is reminiscent of the time the Relativistic Heavy Ion Collider went live. The worry then was that "negative strangelets" could gobble up the world.

PatriceVignon writes "Are private buyout companies setting their eyes on Microsoft? The Financial Times claims exactly that in an article called 'Private equity folk could do wonders with Microsoft', as ZDnet reports: 'Consider Microsoft, which has a balance sheet so inefficient that it would make a private equity investor weep ... The new management could take the axe to Microsoft's $6.6bn of wasteful research and development expenditure. The bloated workforce of more than 60,000 could be slashed, to the point where the huge resulting increase in cash flow would at last permit the company to borrow mega-billions.' Business Week, though, begs to differ: 'practically speaking, it's not going to happen,' and quotes Daniel Primack: 'Snakes on a Plane will win a best picture Oscar before Microsoft gets acquired by LBO firms.' What do you think?"

Krishna Dagli writes "This weekend provides one of the year's best opportunities to see some "shooting stars". The annual Perseid meteor display is expected to peak on Friday and Saturday night. Meteors are bits of dust or rock that plunge into the Earth's atmosphere and burn up, making bright streaks in the sky. It does not take a large object to produce a visible meteor — most are the size of a grain of sand or a small pebble."
