Submission + - Radical Solution To Global Warming Proposed

john83 writes: "Global Warming is the subject of a lot of debate these days, and some scientists have tried to consider fixes more drastic (and unfathomably expensive) than banning light bulbs. "At the NASA Institute for Advanced Concepts (NIAC) meeting last fall, Roger Angel, an astronomer and optics expert at the University of Arizona, produced a highly detailed — and highly futuristic — proposal for a sunshade huge enough to cut incoming sunlight by 1.8 percent. That, he says, should counteract the warming expected from a doubling of atmospheric carbon dioxide." Story. NIAC has previously brought us such ideas as magnetised beam plasma propulsion which was discussed on Slashdot."

When the Earth Was Purple 278

Ollabelle writes "It's always been a bit of a mystery why plants absorb red and blue light, reflecting green, when the sun emits the peak energy of the visible spectrum in the green. A new theory offers one possible answer: that the first chlorophyll-utilizing microbes evolved to exploit the red-and-blue light that older green-absorbing microbes didn't use, eventually out-competing them through greater efficiency and the rise of oxygen."

Submission + - Apple's growth

website design writes: "Apple Inc. has a decent shot of outgrowing Microsoft Corp. within the next five years if it can keep churning out hit wonders, an extrapolation of revenue data from the two industry heavyweights has revealed. An analysis at 10Layers points out that while both Microsoft and Apple have seen healthy revenue growth in the last 5 years, Apple is growing at a near exponential rate compared to Microsoft's linear path. For more on the subject you shall visit me at:ecommerce web site design .Anyay coming to the point"Microsofts revenues have grown approximately 60 percent from just under $30B in 2002 to over $44B in 2006," the report states. Given that 44B — 30B = 14B, and that 14B = 46.7% not 60%, I am less than sanguine about the accuracy of the rest of the report. "However, while Microsoft has grown linearly for this period, Apple has accelerated with revenues of just under $6B in 2002 growing to just under $21B in 2006." For Apple, that represents an impressive 250 percent revenue growth. In an attempt to predict the future growth rates of both firms, 10Layers compiled an extrapolation of Microsofts linear and Apple's almost exponential revenue growth from the past twelve months. The pure extrapolation shows that Apple could catch up with Microsoft as early as 2010 or 2011, given the current growth rates. Interesting assumptions and calculations. But this is revenue growth not market share growth- which is fine in terms of the bottom line that shareholders care about. I just wonder what their prediction would be about market share. Could Apple surpass Microsoft and yet have only 15% of the market share? Comparing Apple and Microsoft is difficult, given that Apple has self-branded hardware exclusively and Microsoft does not."

Submission + - Karl Auerbach: ICANN is the USSR of the Internet

gnaremooz writes: Karl Auerbach, the last publicly elected board member at ICANN, has been involved with internet development almost since the inception of the internet itself, and served as North America's direct representative on ICANN's Board of Directors. The Register thought Auerbach would have some interesting things to say about recent developments at the controversial group that runs the internet we all know and love.

Submission + - Taming Open Source

An anonymous reader writes: Based on the engine of the popular Swik.net community, SourceLabs is offering a new way to manage open source software. CNet calls it "taming open source" and the announcement is available here. The idea for the product was the result of SourceLabs customers asking for a way to better manage a growing number of open-source products within their companies, said CEO Byron Sebastian.

Submission + - Chinese students better at math

mdahlman writes: "The BBC reports that Chinese university students are significantly more advanced in math (or maths) than their British counterparts. The Royal Society of Chemistry is drawing attention to this as a looming problem by offering the opportunity to answer a geometry problem from a Chinese university entrance exam for a chance to win £500. Direct link to the question (pdf warning)."
