Roland Piquepaille writes "Using a new hybrid material made of nanometer-sized "buckyballs" and a polymer, Canadian researchers have shown that nanotechnology could lead to an Internet based entirely on light and 100 times faster than today's. This material allowed them to use one laser beam to direct another with unprecedented control, a featured needed inside future fiber-optic networks. These future fiber-optic communication systems could relay signals around the global network with picosecond (one trillionth of a second) switching times, resulting in an Internet 100 times faster. Please note this discovery appeared in a lab: we'll have to live with our current networks for some time. This overview contains more details."

Dr_Barnowl writes "The BBC reports on the hydrogen economy in today's Tech column, with an article that shines a positive light on nanotechnlogy; while the focus is on solar hydrogen production, nanocrystalline materials manage to bathe in the reflected glow. The public perception of green energy is a good one, and nanotech can only benefit from being associated with it."

Roland Piquepaille writes "By combining scanning probe microscopy and femtosecond laser techniques, a team of American researchers was able to take snapshots of the movement of molecules in a billionth of a second. The researchers said this is a significant advance in surface science, which studies phenomena such as the formation of crystals and the activity of catalysts that transform pollutants into benign gasses. Their next step will be to shoot real-time, real-space movies of molecular motions. This overview contains more details and an illustration of the process of using femtosecond laser pulses to measure molecular movements at a nanoscale level. It also contains other references to femtosecond lasers."

Roland Piquepaille writes "When you hear the word 'nanotechnology,' I bet you immediately think about nanochips or ultra-small medical devices. But do you know that nanotechnology is starting to be used in highways, bridges and other buildings? In "Small Science Will Bring Big Changes To Roads," a very long article from Better Roads Magazine, you'll discover that "research in structural polymers could lead the way to guardrails that heal themselves, or concrete or asphalt that heal their own cracking." Nanotechnology is also used to design better steel or concrete. And there are even nanosensors in place on the Golden Gate Bridge to monitor its behavior. The nanotechnology revolution is on its way, even if self-healing potholes and guardrails are still science fiction. This long article discusses nanotechnology advances in concrete and cement, self-cleaning traffic signs or better steel. This shorter overview contains selected excerpts about embedded nanosensors, self-healing pavements and smart dust."

Foresight Institute has appointed Scott Mize to the position of President. "This is an important step in our evolution," said Christine Peterson, Founder and former President of Foresight Institute. Peterson will remain with Foresight Institute as Vice President focusing on public policy, legislative issues and education.

Roland Piquepaille writes "Building computer chips which use light instead of electricity will be possible in a few years, thanks to the new techniques developed by two separate research teams from the MIT and Kyoto University. Both have built photonic crystals that can be manufactured using processes suited to mass production. Technology Research News says that "the techniques could be used to make smaller, more efficient communications devices, create optical memory and quantum computing and communications devices, develop new types of lasers and biological and chemical sensors, and could ultimately lead to all-optical computer processors." Please read this overview for more details and references about the two different approaches towards photonic chips, which measure only hundreds of nanometers -- right now."

Roland Piquepaille writes "An interdisciplinary team of researchers at Arizona State University (ASU) has discovered a new nanotechnology effect, the ability of moving water molecules by light. This is a far better way than current methods such as damaging electric fields and opens the way to a new class of microfluidic devices used in analytical chemistry and for pharmaceutical research. For example, this makes possible to design a device that can move drugs dissolved in water, or droplets of water and samples that need to be tested for environmental or biochemical analyses. Please read this overview for more details and references, plus an image of two water drops illuminated with a fluorescent dye and sitting respectively on a nanowire surface and on a flat surface."

Roland Piquepaille writes "The new Scripps-PARC Institute for Advanced Biomedical Sciences (SPIABS for short) is the fruit of the union between Xerox's PARC and the Scripps Research Institute in La Jolla and promises to transform medical research and the practice of medicine. The Mercury News writes that it's making a big leap to innovation in medicine. SPIABS already announced an enthalpy array, an extremely precise nanocalorimeter. It can detect changes of millionths of a degree in temperature, using samples of only 240 nanoliters. This nanocalorimeter will be used to "help pharmaceutical companies quickly pick out the best drug candidates and get improved medications to market sooner." Earlier this year, SPIABS unveiled the FAST cytometer, a laser scanning device so precise it can spot a single cancerous cell in the middle of the ten other millions contained in a standard blood sample. And SPIABS is working on other projects, such as sutures sewn on the perimeter of a removed tumor, equipped with laser diodes to spot and kill new cancerous cells as soon as they appear. Please read this overview for more details, references and pictures."
