Nanorings

What appear under an atomic force microscope to be tiny rings with little bits missing are actually nanoscopic rings made of double-stranded DNA with a little gap in the form of a short single-stranded fragment. This gap is a place to attach other molecules that have the potential to transform the rings into versatile nanocomposites for various applications.

Nanoswitches toggled by light

Microscopic fissures in a tiny crystal open and closeâ??on command. Researchers successfully used ultrafast electron microscopy to observe nanoscopic structures at their 'exercises', as they report in the journal Angewandte Chemie. Such switchable nanochannels could be useful for future nanoelectronics and nanoscopic 'machines'.

Cellular construction methods emulated

Not only is our body made of individual organs, our cells themselves are made of tiny organelles, a variety of separate compartments that fulfill different tasks. Such functional, nanostructured systems would also be useful for technical applications, such as biosensors, self-repairing materials, optoelectronic components, or nanocapsules. However, it has not been possible to recreate structures with sufficient complexity in the lab. Researchers in the Netherlands are now pursuing a new angle.

Pentagon releases new analysis of Chinaâ??s military development and strategy

The Pentagon on Monday released its latest analysis of China's military development and strategy and says that the country spent as much as $139 billion, more than three times its announced defense budget, modernizing its military forces last year and that China has gone from virtually no research or funding in nanotechnologies and processes five years ago, to being a close second to the United States in total government investment.

Biological electron transfer captured in real time

Two research teams led by Dr. Michael Verkhovsky and Prof. Marten Wikstrom of the Institute of Biotechnology of the University of Helsinki have for the first time succeeded in monitoring electron transfer by Complex I in real time. In the future, this work might, for example, have medical relevance, because most of the maternally inherited so-called mitochondrial diseases are caused by dysfunction of Complex I.

Surface dislocation nucleation: Strength is but skin deep at the nanoscale

Researchers at the University of Pennsylvania have found that, while metals tend to be stronger at nanoscale volumes, their strengths saturate at around 10-50 nanometers diameter, at which point they also become more sensitive to temperature and strain rate.
