Geoethical nanotechnology workshop to explore downloading human minds
The Workshop, accessible to the general public as a webinar, will explore downloading minds into bio-nano bodies and similar technologies thought to be essential for interstellar colonization. Geoethical nanotechnology is atom-by-atom assembly techniques that are subject to a consensual review, approval and audit process.

Miraculous mosquito legs
The secret to mosquito water walking appears to be feathery scales a few microns across that in turn are covered with nanoscopic ribbing, forming what the physicists have dubbed (in an apparent fit of excessive prefixing) a micronanostructure.

On a wire or in a fiber, a wave is a wave
In an experiment modeled on the classic "Young's double slit experiment" researchers have powerfully reinforced the understanding that surface plasmon polaritons move as waves and follow analogous rules.

Modern redux of classic experiment illuminates nanoscience of 'plasmonics'
The science of plasmonics describes how metals can essentially transmit and manipulate light waves at length scales much smaller than their wavelengths. Now, by redoing a classic optics experiment with plasmonics, engineers have made key insights into the nature and the practical limits of this up-and-coming nanoscale information technology.

Speed bumps less important than potholes for graphene
For electrical charges racing through an atom-thick sheet of graphene, occasional hills and valleys are no big deal, but the potholes - single-atom defects in the crystal - theyâ??re killers.

EU Parliament votes for tougher food additives regulation
The EU Parliament drew attention to the gap in knowledge of potential risks associated with nanotechnology, saying that the permitted limits for an additive in nanoparticle form should not be the same as when it is in traditional form.

Big improvement for little pictures
Physicists describe a new way to view three-dimensional structures in real time. Although they haven't yet published 3-D movies, they managed to reconstruct the heights of tiny droplets using still images from 2-D movies.
