"The BBC has an article detailing new efforts to replace plastics used in products and construction with newer, less environmentally harmful alternative materials," writes Slashdot reader dryriver. The new products mentioned in the report include: Stone Wool: To transform one of the world's most abundant resources into something with utility and sustainability takes a special kind of alchemy. Stone wool comes from natural igneous rock -- the kind that forms after lava cools -- and a steelmaking byproduct called slag; these substances are melted together and spun into fibers, a little like candyfloss.

Mycotecture: Mushrooms aren't just a flavor-packed addition to ravioli or ragu (or a sparkplug to the occasional psychedelic adventure); soon, tree-hugging fungi and forest-floor toadstools may replace materials like polystyrene, protective packaging, insulation, acoustic insulation, furniture, aquatic materials and even leather goods.

Urine Bricks: Cement, concrete's primary ingredient, accounts for about 5% of the world's carbon dioxide emissions. Researchers and engineers are working to develop less energy-intensive alternatives, including bricks made with leftover brewery grains, concrete modeled after ancient Roman breakwaters (Romans made concrete by mixing lime and volcanic rock to form mortar, a highly stable material), and bricks made of, well, urine. As part of his thesis project, Edinburgh College of Art student Peter Trimble was working on an exhibit that was supposed to feature a module on sustainability. Almost by accident, he created "Biostone": a mixture of sand (incidentally, one of Earth's most abundant resources), nutrients, and urea -- a chemical found in human urine.

A greener particleboard: Despite what it sounds like, particleboard -- those rigid panels made of compressed and veneered wood chips and resin used in furniture and kitchen cabinetry throughout the world -- hasn't actually a place in the green-building pantheon. That's because the glue that binds particleboard's wood fibers traditionally contain formaldehyde, a colorless, flammable, strong-smelling chemical and known respiratory irritant and carcinogen. That means your faux-wood Ikea shelf is quietly "off-gassing" toxins into the air. One company, NU Green, created a material made from 100% pre-consumer recycled or recovered wood fibre called "Uniboard." Uniboard saves trees and avoids landfill, while also generating far fewer greenhouse gases than traditional particleboard, and contains no toxins. That's because Uniboard has pioneered the use of renewable fibers like corn stalks and hops, as well as no added formaldehyde (NAF) resin instead of glue.

In the Estonian capital of Tallinn, three-day-old Oskar Lunde sleeps soundly in his hospital cot, snuggled into a lime green blanket decorated with red butterflies. Across the room, his father turns on a laptop. "Now we will register our child," Andrejs Lunde says with gravity as he inserts his ID card into the card reader. His wife, Olga, looks on proudly. And just like that, Oskar is Estonia's newest citizen. No paper. No fuss. From a report: This Baltic nation of 1.3 million people is engaged in an ambitious project to make government administration completely digital to reduce bureaucracy, increase transparency and boost economic growth. As more countries shift their services online, Estonia's experiment offers a glimpse of how interacting with the state might be for future generations. Need a prescription? It's online. Need someone at City Hall? No lines there -- or even at the Department of Motor Vehicles! On the school front, parents can see whether their children's homework was done on time.

Estonia has created one platform that supports electronic authentication and digital signatures to enable paperless communications across both the private and public sectors. There are still a few things that you can't do electronically in Estonia: marry, divorce or transfer property -- and that's only because the government has decided it was important to turn up in person for some big life events. This spring, government aims to go even further. If Oskar had been born a few months later, he would have been registered automatically, with his parents receiving an email welcoming him into the nation.

A reader sends this excerpt from Space.com: It might make the astronaut wearing it look like a real-life Buzz Lightyear, but a new prototype spacesuit that NASA just finished testing represents the first major overhaul in spacesuit technology since 1998. Flexible, white, and lime green accented, the suit — known as the Z-1 — is designed not only to help astronauts comfortably maneuver during spacewalks in microgravity, but also to deftly move about when walking on the surface of a planet or other smaller heavenly body, like an asteroid. [Engineer Amy Ross] said, 'the shuttle EMU splits at the waist and you put pants on and you put the top on separately and they connect in the middle. Whereas with this suit, the subject crawls in through the back, and then we just shut the door.' Creating a back-entry suit solves a few of the problems spacewalkers often face during trips to the International Space Station. Using airlocks to depressurize is a time consuming, exhausting process. By using a back-entry design, the astronauts won't need to go through an airlock at all. The suit hooks up to the outside of the spacecraft using the "space port" opening, and the spacewalker simply climbs in and detaches."

BogusToo writes to mention an EE Times article describing the interface for the OLPC project laptop. Using some fairly intuitive UI concepts (like simplified web browsers and a chat client), the Linux-based system attempts to do away with the kludgey parts of computer use. A video demo of the interface has been placed on YouTube. From the article: "Earlier postings around the Internet have also shown how the physical design of the laptop has changed, including the elimination of the much touted on-board hand crank that was supposed to power the cheap, lime green laptop. It's still there, reportedly, but has now been moved to the power adapter. The OLPC's produced earlier this week in Shanghai still need to go through loads of testing, such as knocking them off desks and dropping them in mud, as kids are wont to do. They may also be kicked around, like soccer balls, a popular sport in 99.9 percent of the world."

An anonymous reader writes " Do you envy new Apple 17" PowerBook keyboard? Here's keyboard light kits for all most any keyboard no matter which OS you are using. There's NINE choice of colors (Light Blue, Deep Blue, Hot Pink, Yellow, White, Purple, Neon Green, Lime Green, and Red) available but unfortunately not coming with light sensor. "

clemens writes "A Japanese manufacturer has come up with this spherical PC." I love the concept of your PC accidentally rolling off your desk. Doesn't that lime green one remind anyone else of Gundam?

Way back in October we solicited ideas for Christmas presents for geeks. This was done with Wired, and the results appear in the current issue (the lime-green colored one: unless you're blind, you can't miss it. You'll only be able to find the first copy, tho). The authors' money will be a nice Christmas present to the EFF. Thanks go to Paul, who did all the really hard work compiling the final list from all your ideas. Now read on to see the list.
