Simpler Optical Invisibility Developed

Purdue University researchers have a simpler method for optical invisibility using a “tapered optical waveguide” design instead of metamaterials. The research team used their specially tapered waveguide to cloak an area 100 times larger than the wavelengths of light shined by a laser into the device, an unprecedented achievement. Previous experiments with metamaterials have been …

DNA Wrapped Carbon Nanotubes for Tissue Replacement

Tough and soft: Highly porous, spongelike materials self-assemble by calcium ion condensation of DNA-wrapped carbon nanotubes (SWNTs-DNA; see picture, IL=ionic liquid). The toughness, modulus, and swellability of the electrically conductive sponges can be tuned by controlling the density and strength of interfiber junctions. The sponges have compliances similar to the softest natural tissue, while robust …

Nanoscale Reversible Mass Transport for Archiving Computer Memory that Can Last One Billion Years

Nanoscale reversible mass transport computer memory has been demonstrated by Zettl Research Group, Lawrence Berkeley National Laboratory and University of California at Berkeley. In separate but related research in Japan, Daisuke Takagi at NTT Basic Research Laboratories in Atsugi, Japan, decided to replace the metal nanoparticles (the seeds for growing carbon nanotubes) with a densely …

Any Sufficiently Advanced Technology is Indistinguishable from Magic: Beyond Invisibility Illusion Optics

Researchers from the Hong Kong University of Science and Technology propose to use transformation optics [advanced metamaterials] to generate a general illusion such that an arbitrary object appears to be like some other object of our choice. This is achieved by using a remote device that transforms the scattered light outside a virtual boundary into …

Making Square Centimeters of Graphene on Copper and Graphene Transistor Progress

1. Large-Area Synthesis of High-Quality and Uniform Graphene Films on Copper Foils. Graphene films of the order of centimeters were grown on copper substrates by chemical vapor deposition using methane. The films are predominantly single-layer graphene with a small percentage, 3. MIT has an overview of current graphene research. Anticipated Uses for Graphene Electronics “Graphene …

E-books with Larger Screens and Soon Brighter Color

A prototype in-plane electrophoretic display consisting of 1,000 pixels. Credit: Philips MIT TEchnology Review reports A new approach developed by Philips now offers fresh hope for color e-paper displays that are so bright and clear that even traditional liquid crystal displays (LCDs) will pale in comparison. The new approach has the potential to create color …

Update on Cheap Robotic Arms and IBMs Attempt to Revolutionize Automated Question Answering

1. Heartland Robotics Update Rod Brooks, of Heartland Robotics, pointed out that between iRobot and Foster-Miller, New England has a virtual lock on the military robot business. Brooks wouldn’t give details about what his own company, Heartland Robotics, is up to—but he did say that it’s working on systems that will help American workers be …

Science Confirms the Obvious : Very Fat Men Less Likely to be Married by 40

Men who were grossly overweight at the age of 18 had nearly 50 percent less chance of being married by their 30s and 40s, an international conference on obesity heard in Amsterdam. The findings, which held true regardless of the men’s intellectual performance or socio-economic position, could suggest that women rank a man’s appearance higher …
