Bonhams Stafford Spring sale has been responsible for more sales of elite motorcycles than any other single sale anywhere in the world, rivaling even the combined January Las Vegas sales – it's that important. Not surprisingly, there are a number of very rare and valuable motorcycles going under the hammer on April 26, the most significant being a 1939 Vincent-HRD Series-A Rapide (US$320,000-380,000), an unraced 1979 Ducati 900 NCR Racer ($120,000-180,000), a 1926 Coventry Eagle Flying Eight ($120,000-180,000) and a 1930 Brough Superior 680 Black Alpine ($100,000-150,000).

Next-generation lithium-ion batteries may hold more charge for a greater number of cycles thanks to a new material derived from natural silk. Scientists at the Beijing Institute of Technology found that not only does their regenerated silk fibroin material work for over 10,000 cycles but it also stores five times more lithium than graphite, which is the most common choice for the anode (negative electrode) in lithium-ion batteries.

Imagine if there were a remote-control electronic device that could be implanted at an infection site, where it would treat the infection by heating or medicating the affected tissue. While it might be very effective, subsequent infections could result if surgeons went in to remove it, or even if they just left it in place. That's why scientists from Tufts University and the University of Illinois at Champaign-Urbana have developed infection-treating implants that simply dissolve into the body once they've served their purpose.

Silk is an amazingly strong material, yet it also harmlessly biodegrades when left in the body. This has led to its use in experimental brain implants, heart patches, and even bio-electronics. According to a new study conducted by scientists at Tufts University School of Engineering and Beth Israel Deaconess Medical Center, it may now also find use in the production of better plates and screws used for securing broken bones.

Like most other fabrics, silk is colored with dye. Unfortunately, the dyeing process results in wastewater laden with toxins. Now, however, scientists from the National Chemical Laboratory in India are developing an alternative. They're feeding dye to silkworms, which in turn are producing pre-colored silk fibers.

The group of neurological disorders known as epilepsy not only cause disruptive, alarming seizures, but those seizures also tend to increase in frequency and severity over time. While the majority of patients can gain some control of their condition via medication or surgery, approximately 30 percent cannot. Now, however, help may be on the way ... in the form of tiny pieces of silk implanted in the brain. Read More
Spider silk is a truly remarkable material: it's tougher than Kevlar, strong as steel, lighter than carbon fiber, and can be stretched 40 percent beyond its original length without breaking. Now, Japanese startup Spiber says it has found a way to produce it synthetically and, over the next two years, will step up mass production to create anything from surgical materials to auto parts and bulletproof vests.

Silk Pavilion by MIT Media Lab poses some interesting questions about how what it calls "biological fabrication" might fit into the future of making things alongside 3D printing and similar computer-aided cleverness. To make the silk and metal dome, the work begun by robotic weavers was completed by silkworms – 6,500 of them. Read More
