How natural channel proteins move in artificial membranes
Natural channel proteins are integrated into artificial membranes to facilitate the transport of ions and molecules. Researchers at the University of Basel have now been able to measure the movement of these channel proteins for the first time. They move up to ten times slower than in their natural environment, namely the cell membrane. As reported in academic journal 'Nano Letters', the results may prove useful to the ongoing development of new applications such as nanoreactors and artificial organelles.

Researchers simulate behavior of 'active matter'
From flocks of starlings to schools of fish, nature is full of intricate dynamics that emerge from the collective behavior of individuals. In recent years, interest has grown in trying to capture similar dynamics to make self-assembling materials from so-called 'active matter.' Researchers from Brown University have shed new light on the dynamics of one type of active matter known as active colloids.

Measuring the mass of molecules on the nano-scale
Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error -- potentially enabling the weighing of individual molecules in liquid environments. The findings are published this week in Applied Physics Letters.

New sensing tech could help detect diseases, fraudulent art, chemical weapons
Discovered in the 1970s, SERS is a sensing technique prized for its ability to identify chemical and biological molecules in a wide range of fields. It has been commercialized, but not widely. That may soon change. An international research team led by University at Buffalo engineers has developed nanotechnology that promises to make SERS simpler and more affordable.

Engineers win grant to make smart clothes for personalized cooling and heating
Imagine a fabric that will keep your body at a comfortable temperature -- regardless of how hot or cold it actually is. That's the goal of an engineering project at the University of California, San Diego, funded with a $2.6M grant from the US Department of Energy's Advanced Research Projects Agency -- Energy. Wearing this smart fabric could potentially reduce heating and air conditioning bills for buildings and homes.

Novel X-ray lens sharpens view into the nano world
A team led by DESY scientists has designed, fabricated and successfully tested a novel X-ray lens that produces sharper and brighter images of the nano world. The lens employs an innovative concept to redirect X-rays over a wide range of angles, making a high convergence power. The team led by Dr. Saša Bajt from DESY presents the novel lens in the journal Scientific Reports.

Experiment confirms quantum theory weirdness: ANU media release
The bizarre nature of reality as laid out by quantum theory has survived another test, with scientists performing a famous experiment and proving that reality does not exist until it is measured. Physicists at The Australian National University have conducted John Wheeler's delayed-choice thought experiment, which involves a moving object that is given the choice to act like a particle or a wave. The group reversed Wheeler's original experiment, and used helium atoms scattered by light.

New technique speeds nanoMRI imaging
NanoMRI is a scanning technique that produces nondestructive, high-resolution 3D images of nanoscale objects, and promises to become a powerful tool. Producing images with near-atomic resolution, however, is difficult and time-consuming. Striving to overcome this limitation, researchers have developed a parallel measurement technique, which they report in Applied Physics Letters. Information that normally would be measured sequentially -- one bit after another -- can now be measured at the same time with a single detector.

Scientists at the US Department of Energy's Brookhaven National Laboratory have just taken a big step toward the goal of engineering dynamic nanomaterials whose structure and associated properties can be switched on demand. In a paper appearing in Nature Materials, they describe a way to selectively rearrange the nanoparticles in three-dimensional arrays to produce different configurations, or phases, from the same nano-components.

Basel physicists develop efficient method of signal transmission from nanocomponents
Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal Nature Communications together with their colleagues from ETH Zurich.
