Computer security systems may one day get a boost from quantum physics, as a result of recent research from the National Institute of Standards and Technology (NIST). Computer scientist Yi-Kai Liu has devised a way to make a security device that has proved notoriously difficult to build - a 'one-shot' memory unit, whose contents can be read only a single time.

Using an approach akin to assembling a club sandwich at the nanoscale, National Institute of Standards and Technology (NIST) researchers have succeeded in crafting a uniform, multi-walled carbon-nanotube-based coating that greatly reduces the flammability of foam commonly used in upholstered furniture and other soft furnishings.

An AFM's cantilever has a fine tip that can be used to map surfaces at the nanoscale. The movements of the tip are monitored using laser light reflected from the cantilever. If you could manufacture a hollow cantilever and pass a liquid through it, as happens in a fountain pen, then you could kill two birds with one stone.

As if being sick weren't bad enough, there's also the fear of frequent injections, side effects and overdosing on you medication. Now a team of researchers from University of Copenhagen, Department of Chemistry, Nano- science center and the Institut Laue-Langevin, have shown that reservoirs of anti-viral pharmaceuticals could be manufactured to bind specifically to infected tissue such as cancer cells for the slow concentrated delivery of drug treatments.

Storing more and more in an ever-smaller space - what sounds impossible is in fact just part of the daily routine in information technology, where for decades, increasing amounts of data have been successfully stored on media with ever higher densities. An international team has now discovered a physical phenomenon that could prove suitable for use in further data aggregation.
