Scientist cooks up adjustable strength metals

As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg

Graphene-powered web could download 3-D movies in seconds, give MPAA nightmares

Graphene, is there anything it can't do? Researchers are already trying to put it in processors, fuel cells, and batteries -- now your internet connection might get ten-times faster thanks to the silicon successor. Researchers at UC Berkeley have created tiny, one-atom-thick modulators that could switch the data-carrying light on and off in a fiber-optic connection much faster than current technology. In addition to running at a higher frequency (the team believes it will scale up to 500GHz -- modern modulators run at about 1GHz) the smaller, 25-micron size means thinner cables could be used, reducing capacitance and further boosting speeds. Labs have already crossed the 100 terabit threshold and graphene could push that even higher, yet we're still stuck staring at a buffering screen every time we try to Netflix  Degrassi .

Bee venom used to create ultra-sensitive explosives sensor

We knew that well-trained bees were capable of sniffing out dynamite and other explosives, but researchers at MIT have now come up with a slightly less militant way to use our winged friends as bomb detectors. A team of chemical engineers at the school recently developed a new, ultra-sensitive sensor that's sharp enough to detect even one molecule of TNT. Their special ingredient? Bee venom. Turns out, a bee's poison contains protein fragments called bombolitins, that react to explosive compounds. To create the detector, researchers applied these bombolitins to naturally fluorescent carbon nanotubes. Whenever an explosive molecule binds with the protein fragments, the interaction will alter the wavelength of the carbon cylinder's fluorescent light. The shift is too small for the naked eye to pick up on, but can be detected using specially designed microscopes. If it's ever developed for commercial use, the sensor could provide a more acute alternative to the spectromet...

Nano Technology With Nokia Morph

Nano Technology has evolved as an all together different technology area in the mobile world. Mobile phones are advancing at a great and faster pace than never before and Nokia Morph is truly a mobile wonder. This phone has been developed by Nokia Research Center and the University of Cambridge (UK). The Morph specialty lies in the design and technology used to make it possible. The best part of this phone is that you can transform it according to your wish and that what exactly Nokia wanted to come up with- Flexible and Reliable phone. You can radically change the phone in different shapes one of being the bracelet way. Professor Mark Welland, Head of the Department of Engineering’s Nanoscience Group at the University of Cambridge and University Director of Nokia-Cambridge added, “Developing the Morph concept with Nokia has provided us with a focus that is both artistically inspirational but, more importantly, sets the technology agenda for our joint nanoscience research that will st...
