An anonymous reader writes "BBC reports that Dr. Aaron Davis of the Royal Botanical Gardens claims 'almost three-quarters of the world's wild coffee species are threatened, as a result of habitat loss and climate change. "Conserving the genetic diversity within this genus has implications for the sustainability of our daily cup, particularly as coffee plantations are highly susceptible to climate change.'"

Hugh Pickens writes "New Scientist reports that instead of identifying chemicals that could point to life, NASA's robot explorers may have been toasting them by mistake. Even if Mars never had life, comets and asteroids that have struck the planet should have scattered at least some organic molecules over its surface but landers have failed to detect even minute quantities of organic compounds. Now scientists say they may have stumbled on something in the Martian soil that may have, in effect, been hiding the organics: a class of chemicals called perchlorates. At low temperatures, perchlorates are relatively harmless but when heated to hundreds of degrees Celsius perchlorates release a lot of oxygen, which tends to cause any nearby combustible material to burn. The Phoenix and Viking landers looked for organic molecules by heating soil samples to similarly high temperatures to evaporate them and analyse them in gas form. When Douglas Ming of NASA's Johnson Space Center in Houston, Texas, and colleagues tried heating organics and perchlorates like this on Earth, the resulting combustion left no trace of organics behind. "We haven't looked the right way," says Chris McKay of NASA's Ames Research Center. Jeffrey Bada of the University of California, San Diego, agrees that a new approach is needed. He is leading work on a new instrument called Urey which will be able to detect organic material at concentrations as low as a few parts per trillion. The good news is that, although Urey heats its samples, it does so in water, so the organics cannot burn up."

An anonymous reader writes "According to the Register, Senator Diane Feinstein is attempting to put language into the stimulus bill that would kill net neutrality. The amendment that her provision was attached to was withdrawn, but lobbyists tell Public Knowledge that Feinstein hopes to put it back into the bill during the closed-door conference committee that reconciles the House and Senate versions." Bad Senator! No Cookie!

Hugh Pickens writes "NASA and the European Space Agency are expected later this week to settle an ongoing debate on whether to send a robotic mission to Jupiter's moon Europa or Saturn's moon Titan. Both are difficult places to get to — a mission to either would cost several billion dollars/euros to build and execute — and both have become alluring targets in the quest to learn whether Earth alone supports life. On the one hand, Europa is believed to have liquid oceans beneath its frozen crust which (on Earth at least) are a source of life-supporting chemistry. Scientists would like to scan Europa's surface for bits of material that may have seeped up from beneath the ice. 'Imagine if there were microbes entrained in material that has exuded onto the surface of Europa and they've been sitting there for maybe three million years,' says planetary scientist Dr. Brad Dalton. On the other hand, Titan has two enticing features in the search for life: liquids on the surface, and a thick atmosphere that can be used to slow down a spacecraft and help put it into orbit. Titan's surface water is locked into the crust as ice, but scientists suspect there may be a subsurface ocean where water mingles with ammonia. The mission will not get to the launch pad before 2020. 'It's unfortunate that there has to be a decision,' says NASA/JPL astrobiologist Dr. Kevin Hand. 'It's important to go to both. They are both such amazing and tantalizing worlds in terms of finding life.'"

Rob Carr writes "According to the Cassini team, 'Recent images of Titan from NASA's Cassini spacecraft affirm the presence of lakes of liquid hydrocarbons by capturing changes in the lakes brought on by rainfall.' The northern lakes are now larger following a period in which hydrocarbon clouds covered their skies. (The research was published in the journal Geophysical Research Letters.) This change adds to the evidence these areas are indeed hydrocarbon lakes. But this discovery raises several more questions: where is the methane in the atmosphere coming from, and how long can this complex hydrocarbon cycle on Titan go on? The new evidence emphasizes the need for another mission to Titan."

An anonymous reader writes to tell us that a company has demonstrated a new form of wireless communication that uses light instead of radio waves. "Its inventor, St. Cloud resident John Pederson, says visible-light embedded wireless data communication is the next step in the evolution of wireless communications, one that will expand the possibilities in phone and computer use. The connection provides Web access with almost no wiring, better security and with speeds more than eight times faster than cable."

Smivs writes "The BBC are reporting that a German team has confirmed the existence of a Black Hole at the center of the Milky Way. Astronomers tracked the movement of 28 stars circling the center of the Milky Way, using the 3.5m New Technology Telescope and the 8.2m Very Large Telescope (VLT) in Chile. Both are operated by the European Southern Observatory (Eso). The black hole is four million times heavier than our Sun, according to the paper in The Astrophysical Journal. According to Dr Robert Massey, of the Royal Astronomical Society (RAS), the results suggest that galaxies form around giant black holes in the way that a pearl forms around grit."

snydeq writes "Ars Technica's Nate Anderson and InfoWorld's Paul Venezia provide worthwhile commentary on a recent speech by FCC Commissioner Deborah Taylor Tate (PDF), in which she praised DRM as 'very effective' and raised a flag in favor of ISP filtering. Anderson: 'Having commissioners who feel that the government has a duty to partner with and back educational classroom content from the RIAA; who really believe that ISP filtering is so unproblematic we can stop considering objections; and who think that universities worry about file-swapping because tuition might be raised to pay for the needed "expansion of storage capabilities" (huh?) isn't good for the FCC and isn't good for America.' Venezia: 'Leave the ISPs out of it — it's not their job to protect a failing business model, and a movement toward a tiered and filtered Internet will do nothing to stem the tide of piracy, but will result in great restrictions on innovation, freedoms, and the general use of the Internet. There's nothing to be gained down that path other than possibly to expand the wallets of a few companies.'"

arcticstoat writes "In what could be seen as an easy answer to the Vista-capable debacle, Microsoft has introduced a 'fully conformant software rasterizer' called WARP (Windows Advanced Rasterization Platform) 10, which does away with the need for a dedicated hardware 3D accelerator altogether. Microsoft says that WARP 10 will support all the features and precision requirements of Direct3D 10 and 10.1, as well as up to 8x multi-sampled anti-aliasing, anisotropic filtering and all optional texture formats. The minimum CPU spec needed is just 800MHz, and it doesn't even need MMX or SSE, although it will work much quicker on multi-core CPUs with SSE 4.1. Of course, software rendering on a single desktop CPU isn't going to be able to compete with decent dedicated 3D graphics cards when it comes to high-end games, but Microsoft has released some interesting benchmarks that show the system to be quicker than Intel's current integrated DirectX 10 graphics. Running Crysis at 800 x 600 with the lowest quality settings, an eight-core Core i7 system managed an average frame rate of 7.36fps, compared with 5.17fps from Intel's DirectX 10 integrated graphics."

tytso writes "Suppose there is a book that you want to read on your ebook reader, but it is out of print (so even if you purchase the dead-tree version of the book used, the author won't receive any royalties) and the publisher has refused to make it available as an ebook. You can buy it from Amazon as a used book, but that isn't your preferred medium. It is available on the internet as a pirated etext, however. This blog post outlines a few possibilities, and then asks, 'What is the right thing to do? And why?' I'm also curious if the answers change depending on whether you are a Baby Boomer, or a Gen X, Gen Y, etc. — I've noticed that attitudes around copyright seem to change depending on whether someone is a college student or a recent college graduate, versus someone who can remember a time when the Internet did not exist."

leighklotz writes "In an update to the little green men story of not-life-on-Mars, NASA has twittered: 'The buzz this weekend was due to an interesting soil chemistry finding, still preliminary, but now avail here:' where 'here' is NASA Spacecraft Analyzing Martian Soil Data. The exciting bit: 'Within the last month, two samples have been analyzed by the Wet Chemistry Lab of the spacecraft's Microscopy, Electrochemistry, and Conductivity Analyzer, or MECA, suggesting one of the soil constituents may be perchlorate, a highly oxidizing substance.' Also, 'NASA will hold a media teleconference on Tuesday, Aug. 5, at 2 p.m. EDT, to discuss these recent science activities.'"

buzzardsbay writes "For the past few years, we've heard a number of analysts and high-profile IT industry executives, Bill Gates and Craig Barrett among them, promoting the idea that there's an ever-present shortage of skilled IT workers to fill the industry's demand. But now there's growing evidence suggesting the "shortage" is simply a self-serving myth. "It seems like every three years you've got one group or another saying, the world is going to come to an end there is going to be a shortage and so on," says Vivek Wadhwa, a professor for Duke University's Master of Engineering Management Program and a former technology CEO himself. "This whole concept of shortages is bogus, it shows a lack of understanding of the labor pool in the USA.""

Luyseyal writes "IBM has developed a process for scrubbing waste silicon wafers clean, allowing the otherwise highly secret waste to be sold. The silicon quality usually necessary for solar production is very high and the cost of solar panels reflects it. Recycling this waste should help bring down the cost in the long run and add a new profit vector for chip manufacturers. The article notes that IBM has such a high profile in the chip business that this recycling tech should spread rapidly."
