New Tools for a Nanotechnology Workshop from PhysOrg.com
Until recently, nanoscale devices could only be crafted through chemical reactions or by pushing components together on a smooth surface. Researchers at the Technical University of Denmark have developed and demonstrated practical tools allowing the precise manipulation and assembly of complex, three-dimensional nanomachines.

Growing Glowing Nanowires to Light Up the Nanoworld from PhysOrg.com
The nano world is getting brighter. Nanowires made of semiconductor materials are being used to make prototype lasers and light-emitting diodes with emission apertures roughly 100 nm in diameter—about 50 times narrower than conventional counterparts. Nanolight sources may have many applications, including “lab on a chip” devices for identifying chemicals and biological agents, scanning-probe microscope tips for imaging objects smaller than is currently possible, or ultra-precise tools for laser surgery and electronics manufacturing.

Researchers use bacteria to reduce uranium to safe levels from PhysOrg.com
While the Cold War ended decades ago, its legacy will live for centuries in toxic waste. In remote corners of the country from Tennessee to the Pacific Northwest, dozens of federal laboratories struggle to clean up contaminants left from 50 years of weapons programs. New results show a promising technique for cleaning up uranium from some of the most severely contaminated areas by harnessing the powers of microbes already in the soil.

Carbon fullerenes now have metallic cousins, 'hollow golden cages' from PhysOrg.com
Scientists have uncovered a class of gold atom clusters that are the first known metallic hollow equivalents of the famous hollow carbon fullerenes known as buckyballs. The evidence for what their discoverers call "hollow golden cages" appeared today in the online early edition of the Proceedings of the National Academy of Sciences.

Light's Most Exotic Trick Yet: So Fast it Goes ... Backwards? from PhysOrg.com
In the past few years, scientists have found ways to make light go both faster and slower than its usual speed limit, but now researchers at the University of Rochester have published a paper today in Science on how they've gone one step further: pushing light into reverse. As if to defy common sense, the backward-moving pulse of light travels faster than light. Confused? You're not alone.

Scientist Revs Up Power of Microbial Fuel Cells in Unexpected Ways from PhysOrg.com
Scientists have boosted the power output of microbial fuel cells more than 10-fold by letting the bacteria congregate into a slimy matrix known as a biofilm. The research, led by microbiologist Derek Lovley of the University of Massachusetts Amherst, suggests that efficient technologies for generating electricity with microbes are much closer than anticipated. Lovley presented the results Wednesday in a plenary talk at the meeting of the Electrochemical Society in Denver.

Earth is safe from gamma-ray bursts, Hubble finds from PhysOrg.com
A gamma-ray burst (GRB) occurring in our own galaxy could decimate life on Earth, destroying the ozone layer, triggering climate change and drastically altering life’s evolution. However, the good news is that results published online today in the journal Nature show that the likelihood of a natural disaster due to a GRB is much lower than previously thought.

Nanotube Sandwiches Could Lead To Better Composite Materials from PhysOrg.com
By stacking layers of ceramic cloth with interlocking nanotubes in between, a team of researchers has created new composites with significantly improved properties compared to traditional materials. The “nanotube sandwiches,” which are described in the May 7 online edition of the journal Nature Materials, could find use in a wide array of structural applications.

Scientists demonstrate a breakthrough in fabricating molecular electronics from PhysOrg.com
Scientists from Philips Research and the University of Groningen (the Netherlands) have for the first time fabricated arrays of molecular diodes on standard substrates with high yields. The molecular diodes are as thin as one molecule (1.5 nm), and suitable for integration into standard plastic electronics circuits. Based on construction principles known as molecular self-organization, molecular electronics is a promising new approach for manufacturing electronics circuits in addition to today’s conventional semiconductor processing. Details of the technology are presented in the 4 May 2006 issue of Nature.

Engineers announce breakthrough in nanoscale semiconductor spin wave research from PhysOrg.com
Engineers at the UCLA Henry Samueli School of Engineering and Applied Science are announcing a critical new breakthrough in semiconductor spin-wave research.
UCLA Engineering adjunct professor Mary Mehrnoosh Eshaghian-Wilner, researcher Alexander Khitun and professor Kang Wang have created three novel nanoscale computational architectures using a technology they pioneered called "spin-wave buses" as the mechanism for interconnection. The three nanoscale architectures are not only power efficient, but also possess a high degree of interconnectivity.
