According to a recent story on CBC.ca, a new material has been developed which is the currently renowned for being the lightest material in the world. Known as Aerographite, the material is composed of carbon and weighs roughly one-seventy-fifth that
Ultrafast rechargeable batteries made from low-cost and abundant electrode materials operating in safe aqueous electrolytes could be attractive for electrochemical energy storage.
Scientists have dramatically improved the performance of Thomas Edison's nickel-iron battery. The enhanced device eventually could be used in electric vehicles, much as Edison originally envisioned.
Great video look (1 of 2) into BMW's carbon fiber reinforced plastic manufacturing process at the SGL Automotive Carbon Fibers plants, with which BMW has a joint venture, and at BMW's Landshut plant.
A team of chemists at Stanford have created a nickel-iron battery prototype that can charge and discharge in seconds using carbon nanostructures.
Olympic swimmers don’t just dive into the pool like the rest of us. They start on a block called, appropriately enough, a starting block. London will see the Olympic debut of a track-style starting block with an inclined surface and a lip at the back
Brady Ellison is the top archer on the planet right now. At 23, he’s ranked No. 1 on the recurve bow, a feat made all the more impressive by the fact he didn’t pick up a recurve bow until six years ago.
For years, America’s spies had to take off their shoes before they got on planes, just like the rest of us. No more.

Human beings would be made to look decidedly unimpressive were animals allowed to compete in the Olympics — outperformed by the likes of kangaroos, gorillas and ostriches, a science paper said.
Air traffic control software used around the world could be exploited by hackers to unleash squadrons of ghost planes to befuddle those entrusted to keep the skies safe, a security researcher said Thursday.
As the technology improves, 3D printers are being used more and more to create a wide variety of objects, some incredibly useful (like skeletal implants) and some just for fun (like custom robot figurines).
Harvard University researchers' review of fluoride/brain studies concludes "our results support the possibility of adverse effects of fluoride exposures on children's neurodevelopment."
when ribosome biogenesis is dysregulated, proteins are overproduced, creating rampant cell growth, a hallmark of cancer; and abnormalities of the nucleolus, the site of ribosome biogenesis, have been used as an indicator of cancer for over 100 years
Google asked a US court Friday to dismiss a lawsuit over the Internet giant’s massive book-scanning project, saying the effort is “not a substitute” for books themselves.
