DNA nanotechnology opens new path to super-high-resolution molecular imaging
A team at the Wyss Institute for Biologically Inspired Engineering at Harvard University has been awarded a special $3.5 million grant from the National Institutes of Health to develop an inexpensive and easy-to-use new microscopy method that uses blinking DNA probes to spot many tiny components of cells simultaneously. The method could potentially lead to new ways of diagnosing disease and new insights into how the cell's components carry out their work.

Great potential for faster diagnoses with new method
The more accurately we can diagnose a disease, the greater the chance that the patient will survive. That is why many researchers are working to improve the quality of the diagnostic process. Researchers at the Nano-Science Center, University of Copenhagen have discovered a method that will make the process faster, cheaper and more accurate. This is possible, because they are combining advanced tools used in physics for research in biology at nanoscale, two scientific disciplines usually very distant from each other.

Solar power's future brawl
A trio of researchers at North Dakota State University, Fargo, and the University of South Dakota have turned to computer modeling to help decide which of two competing materials should get its day in the sun as the nanoscale energy-harvesting technology of future solar panels -- quantum dots or nanowires.

'Waviness' explains why carbon nanotube forests have low stiffness
A new study has found that "waviness" in forests of carbon nanotubes dramatically reduces their stiffness. Instead of being a detriment, the waviness may make the nanotube arrays more useful as thermal interface material for conducting heat away from future high-powered integrated circuits.

UW engineers invent programming language to build synthetic DNA
A team led by the University of Washington has developed a programming language for chemistry that it hopes will streamline efforts to design a network that can guide the behavior of chemical-reaction mixtures in the same way that embedded electronic controllers guide cars, robots and other devices. The findings were published online Sept. 29 in Nature Nanotechnology.

The world's sharpest X-ray beam shines at DESY
The world's sharpest X-ray beam shines at DESY. At the X-ray light source PETRA III, scientists from Göttingen generated a beam with a diameter of barely 5 nanometres -- this is ten thousand times thinner than a human hair. This fine beam of X-ray light allows focusing on smallest details. The research groups of Professor Tim Salditt and of Professor Hans-Ulrich Krebs of University of Göttingen published their work in the research journal Optics Express.

Wagon-wheel pasta shape for better LED
One problem in developing more efficient organic LED light bulbs and displays for TVs and phones is that much of the light is polarized in one direction and thus trapped within the light-emitting diode, or LED. University of Utah physicists believe they have solved the problem by creating a new organic molecule that is shaped like rotelle -- wagon-wheel pasta -- rather than spaghetti.

Tiny antennas let long light waves see in infrared
University of Illinois at Urbana-Champaign researchers have developed arrays of tiny nano-antennas that can enable sensing of molecules that resonate in the infrared spectrum. The semiconductor antenna arrays allow long-wavelength light to strongly interact with nano-scale substances, so the arrays could enhance the detection of small volumes of materials.

With carbon nanotubes, a path to flexible, low-cost sensors
Researchers at the Technische Universitaet Muenchen are showing the way toward low-cost, industrial-scale manufacturing of a new family of electronic devices. A leading example is a gas sensor that could be integrated into food packaging to gauge freshness, or into compact wireless air-quality monitors. Flexible pressure and temperature sensors could be built into electronic skin. All these devices can be made with carbon nanotubes, sprayed like ink onto flexible plastic sheets or other substrates.

New multifunctional topological insulator material with combined superconductivity
By employing state-of-art materials design methods, Dr. Binghai Yan and his collaborators from the Max Planck Institute for Chemical Physics of Solids and Mainz University have recently predicted that the oxide compound BaBiO3 combines two required properties, i.e., topological insulator and superconductivity. This material has been known as a high-temperature superconductor of Tc of nearly 30 Kelvin with p-type doping. Now it has been discovered to be also a topological insulator with n-type doping.

A first: Stanford engineers build computer using carbon nanotube technology
Silicon chips could soon hit physical limits preventing them from getting smaller and faster. Carbon nanotube technology has been seen as a potential successor. But so far no one's been able to put all the pieces together. Stanford's CNT computer is therefore an important proof of principle. And while this is a bare-bones device, the processes used to create the world's first CNT computer are designed to scale.

Stanford scientists publish theory, formula to improve 'plastic' semiconductors
We could find many uses for bendable electronics, such as e-readers that folded like newspapers or smart phones that curved in our back pockets. Polymer semiconductors could get us there. But their electrical properties are not well understood. In some novel work Stanford scientists explain how the structure of polymers affects their electrical properties with an eye toward improving their performance as electronic components.
