Race Car Made With Veggies And Powered By Chocolate 83

IS4110 writes "A new racing car made with potatoes and carrots and powered with chocolate waste has been developed by the Innovative Manufacturing Research Centre of the University of Warwicks in the UK. The university's vehicle, called WorldFirst F3 project, has a steering wheel made of curran, a material derived from carrots, that is expected to replace glass fiber and carbon fiber. It also has a racing seat made of SoyFoam, a soybean oil-based, flexible foam material. Wing mirrors incorporate materials derived from potato starch, a bib made from flax fiber, and lubricants based on plant oils."

Scientists Discover Exoplanet Less Than Twice the Mass of Earth 201

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."

Developing Battery Replacement Infrastructure For Electric Cars 369

FathomIT sends in a NY Times profile of Shai Agassi, owner of a company named Better Place, who is working to build the infrastructure to support large numbers of small-scale charging spots for electric cars, as well as fast, automated battery swap stations. "The robot — a squat platform that moves on four dinner-plate-size white wheels — scuttled back and forth along a 20-foot-long set of metal rails. At one end of the rails, a huge blue battery, the size of a large suitcase, sat suspended in a frame. As we watched, the robot zipped up to the battery, made a nearly inaudible click, and pulled the battery downward. It ferried the battery over to the other end of the rails, dropped it off, picked up a new battery, hissed back over to the frame and, in one deft movement, snapped the new battery in the place of the old one. The total time: 45 seconds."

Using Conficker's Tricks To Root Out Infections 117

iago-vL writes "Despite having their domain blacklisted by Conficker, the folks at Nmap have released version 4.85BETA8, which promises better detection of the Conficker worm. How? By talking to it on its own peer-to-peer network! By sending encrypted messages to a suspect host, the tools will get Conficker.C and higher to reveal itself. This curious case of using Conficker's own tricks to find it is similar to the last method that we discussed. More information from the author is available, as well as a download for the new release (or, if you're a Conficker refugee, try a mirror instead)."

The Road To Terabit Ethernet 210

stinkymountain writes "Pre-standard 40 Gigabit and 100 Gigabit Ethernet products — server network interface cards, switch uplinks and switches — are expected to hit the market later this year. Standards-compliant products are expected to ship in the second half of next year, not long after the expected June 2010 ratification of the 802.3ba standard. Despite the global economic slowdown, global revenue for 10G fixed Ethernet switches doubled in 2008, according to Infonetics. There is pent-up demand for 40 Gigabit and 100 Gigabit Ethernet, says John D'Ambrosia, chair of the 802.3ba task force in the IEEE and a senior research scientist at Force10 Networks. 'There are a number of people already who are using link aggregation to try and create pipes of that capacity,' he says. 'It's not the cleanest way to do things...(but) people already need that capacity.' D'Ambrosia says even though 40/100G Ethernet products haven't arrived yet, he's already thinking ahead to terabit Ethernet standards and products by 2015. 'We are going to see a call for a higher speed much sooner than we saw the call for this generation' of 10/40/100G Ethernet, he says."

Google Brings 3D To Web With Open Source Plugin 191

maxheadroom writes "Google has released an open source browser plugin that provides a JavaScript API for displaying 3D graphics in web content. Google hopes that the project will promote experimentation and help advance a collaborative effort with the Khronos Group and Mozilla to create open standards for 3D on the web. Google's plugin offers its own retained-mode graphics API, called O3D, which takes a different approach from a similar browser plugin created by Mozilla. Google's plugin is cross-platform compatible and works with several browsers. In an interview with Ars Technica, Google product manager Henry Bridge and engineering director Matt Papakipos say that Google's API will eventually converge with Mozilla's as the technology matures. The search giant hopes to bring programs like SketchUp and Google Earth to the browser space."

Fair Use Affirmed In Turnitin Case 315

Hugh Pickens writes "The Fourth Circuit Court of Appeals has issued an opinion affirming a ruling that will be cheered by digital fair use proponents for allowing a fair use of students' work when their teachers electronically file students' written work with the turnitin.com Web site so that newly submitted work can be compared against Turnitin's database of existing student work to assess whether the new work is the result of plagiarism. The court stepped through the fair use analysis, dropping positive notes that affirm commercial uses can be fair uses, that a use can be transformative 'in function or purpose without altering or actually adding to the original work,' and that the entirety of a work can be used without precluding a finding of fair use. Techdirt suggests that all of these points could have been helpful to Google in defending its book scanning efforts, 'since it could make pretty much the identical arguments on all points.' Unfortunately Google caved in that lawsuit and settled, 'denying a strong fair use precedent and making Google look like an easy place for struggling industries to demand cash.'"
