Tim Hanlon writes "Biofuels continue to lead the field in the search for a renewable, environmentally friendly replacement for crude oil. Besides its use in the transport industry, crude oil is also used to produce conventional plastics and chemical products such as fertilizers and solvents. Now chemists have learned how to convert plant biomass directly into a chemical building block that can be used to produce not only fuel, but also plastics, polyester, and industrial chemicals, cheaply and efficiently."

vivian writes "Ever since 1996, when I first set eyes on a Sony GlassTron head-mounted display in Japan, I have been awaiting a lightweight, head-mounted display that actually has decent resolution and doesn't look like a brick tied to your face. The closest contender to date seems to be the WRAP 920AV from Vuzix, and they are partially transparent too, which is great, but as with every other unit I have found, they only offer video quality — 640x480. Given that there have been a number of other discussions on Slashdot, I can't be the only one here who is eagerly awaiting something that could actually be a viable alternative to a PC monitor — especially for gaming or 3d graphics work. Perhaps we could petition a manufacturer to make what we actually want? Something with a minimum of 1024x768 @30-60hz refresh, say, and capable of stereo vision. Extra karma if they incorporate head tracking."

bokske writes "An office worker cleaning a fridge full of rotten food created a smell so noxious that it sent seven co-workers to the hospital and made many others ill. Firefighters had to evacuate the AT&T building in downtown San Jose on Tuesday, after the flagrant fumes prompted someone to call 911. A hazmat team was called in. Just another day at the office."

mask.of.sanity writes "Australia's national welfare agency will release its 'unbreakable' AU$560,000 smart card identification protocol for free. The government agency wants other departments and commercial businesses to adopt the Protocol for Lightweight Authentication of ID (PLAID), which withstood three years of design and testing by Australian and American security agencies. The agency has one of Australia's most advanced physical and logical converged security systems: staff can access doors and computers with a single centrally-managed identity card, and user identities can be automatically updated as employees leave, are recruited or move to new departments. PLAID, which will be available soon, is to be used in the agency's incoming fleet of contact-less smartcards that are currently under trial by staff. It will replace existing identity cards that operate on PKI encryption."

Mike writes "It's official: Yahoo is pulling the plug, and GeoCities is dead. GeoCities had suffered a long and drawn-out battle with its health over the past decade. An antiquated service model and outdated technology are widely blamed for the struggle. An official cause of death, however, has yet to be determined. Awful, eye-punishing graphics, lack of relevancy, and 'lowest-common-denominator design' are believed to have contributed to its demise. GeoCities was 15 years old." There is doubtless a lot of funny and informative stuff on there that's worth saving (not just Jesux, which pudge has now migrated). If some of it belongs to you, perhaps you should move it sometime in the next few months. Update: 04/24 18:10 GMT by T : And if you know some GeoCities page owners who aren't especially computer savvy, you could point out to them how easy it is to slurp down their pages for re-hosting elsewhere.

Snowblindeye writes with this excerpt from the European Southern Observatory: "Well-known exoplanet researcher Michel Mayor today announced the discovery of the lightest exoplanet found so far. The planet, 'e,' in the famous system Gliese 581, is only about twice the mass of Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist. Planet Gliese 581 e orbits its host star — located only 20.5 light-years away in the constellation Libra ('the Scales') — in just 3.15 days. 'With only 1.9 Earth-masses, it is the least massive exoplanet ever detected and is, very likely, a rocky planet,' says co-author Xavier Bonfils from Grenoble Observatory. Being so close to its host star, the planet is not in the habitable zone. But another planet in this system appears to be. ... The planet furthest out, Gliese 581 d, orbits its host star in 66.8 days. 'Gliese 581 d is probably too massive to be made only of rocky material, but we can speculate that it is an icy planet that has migrated closer to the star,' says team member Stephane Udry. The new observations have revealed that this planet is in the habitable zone, where liquid water could exist. '"d" could even be covered by a large and deep ocean — it is the first serious "water world" candidate,' continued Udry."

An anonymous reader sends word of a new cybersecurity project to defend US networks from attacks and strengthen the government's "offensive capabilities in cyberwarfare." Right now, the most likely candidate to lead the project is the Director of the NSA, Keith Alexander, who was quick to assert that the NSA itself wouldn't try to run the whole show (something they've been criticized for in the past). Quoting the Wall Street Journal: "Cyber defense is the Department of Homeland Security's responsibility, so the command would be charged with assisting that department's defense efforts. The relationship would be similar to the way Northern Command supports Homeland Security with rescue capabilities in natural disasters. The NSA, where much of the government's cybersecurity expertise is housed, established a similar relationship with Homeland Security through a cybersecurity initiative that the Bush administration began in its final year."

An anonymous reader writes "From a University of Wisconsin-Madison announcement: 'In early April, Adam Wilson posted a status update on the social networking Web site Twitter — just by thinking about it. Just 23 characters long, his message, 'using EEG to send tweet,' demonstrates a natural, manageable way in which "locked-in" patients can couple brain-computer interface technologies with modern communication tools. A University of Wisconsin-Madison biomedical engineering doctoral student, Wilson is among a growing group of researchers worldwide who aim to perfect a communication system for users whose bodies do not work, but whose brains function normally.' A brief rundown of the system: Users focus on a monitor displaying a keyboard; the interface measures electrical impulses in the brain to print the chosen letters one by one. Wilson compares the learning curve to texting, calling it 'kind of a slow process at first.' But even practice doesn't bring it quite up to texting speed: 'I've seen people do up to eight characters per minute,' says Wilson. See video of the system in action."

Recently we covered California utility company PG&E's ambitious deal with upstart Solaren to beam energy to earth from a space-based solar collector. What we didn't know is Solaren's patent also covers the alteration of weather elements with that very same system. "By heating up the upper and middle levels of an infant hurricane, they say they could disrupt the flows of air that power the enormous storms. Air warmed by tropical waters flows up through a hurricane and is vented through the eye into the upper atmosphere. Theoretically, you could heat up the top of the storm and lower the pressure differential between layers, resulting in a weaker storm. "
