Size matters in the giant magnetoresistance effect in semiconductors
In a paper appearing in Nature's Scientific Reports, Dr. Ramesh Mani, professor of physics and astronomy at Georgia State University, reports that a giant magnetoresistance effect depends on the physical size of the device in the GaAs/AlGaAs semiconductor system.

Graphene Flagship has set sails
A flagship sail was symbolically set jointly by Wolfgang Bosch of the European Commission, Karin Markides, President of Chalmers University of Technology, and Nokia's Tapani Ryhänen. The Graphene Flagship was selected as one of Europe's first ten-year, 1,000 million Euro flagships in Future and Emerging Technologies by the European Commission in January 2013. The mission is to take graphene and related layered materials from academic laboratories to society, revolutionize multiple industries and create economic growth and new jobs in Europe.

World record: Wireless data transmission at 100 Gbit/s
Extension of cable-based telecommunication networks requires high investments in both conurbations and rural areas. Broadband data transmission via radio relay links might help to cross rivers, motorways or nature protection areas at strategic node points, and to make network extension economically feasible. In the current issue of the nature photonics magazine, researchers present a method for wireless data transmission at a world-record rate of 100 gigabits per second.

Researchers find rust can power up artificial photosynthesis
Scientists trying to develop artificial photosynthesis for unique applications, like harvesting solar energy, have focused on narrowing the photovoltage gap between the two principle reactions of oxidation and reduction. Boston College chemists report nearly bridging that gap using inexpensive materials in a process that could lead to new energy applications.

Major leap towards graphene for solar cells
Dr. Marc Gluba and Professor Dr. Norbert Nickel of the HZB Institute for Silicon Photovoltaics have shown that graphene retains its impressive set of properties when it is coated with a thin silicon film. These findings have paved the way for entirely new possibilities to use in thin-film photovoltaics.

3-D printed microscopic cages confine bacteria in tiny zoos for the study of infections
University of Texas at Austin researchers have used a novel 3-D printing technology to build homes for bacteria at a microscopic level. Their method uses a laser to construct protein "cages" around bacteria in gelatin. The resulting structures can be of almost any shape or size, and can be moved around in relationship to other structures containing bacterial microcommunities.

Cells prefer nanodiscs over nanorods
For years scientists have been working to fundamentally understand how nanoparticles move throughout the human body. One big unanswered question is how the shape of nanoparticles affects their entry into cells. Now researchers have discovered that under typical culture conditions, mammalian cells prefer disc-shaped nanoparticles over those shaped like rods.

Laying down a discerning membrane
One of the thinnest membranes ever made is also highly discriminating when it comes to the molecules going through it. Engineers at the University of South Carolina have constructed a graphene oxide membrane less than 2 nanometers thick with high permeation selectivity between hydrogen and carbon dioxide gas molecules.

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.

UC Berkeley, Berkeley Lab announce Kavli Energy NanoSciences Institute
The Kavli Foundation has endowed a new institute at UC Berkeley and Lawrence Berkeley National Laboratory to explore the basic science of how to capture and channel energy on the molecular or nanoscale, with the potential for discovering new ways of generating energy for human use. The researchers seek to understand how solar, heat and vibrational energy are captured and converted into useful work by plants and animals or novel materials.

New method allows quantitative nanoscopic imaging through silicon
A team of scientists from The University of Texas at Arlington and MIT has figured out how to quantitatively observe cellular processes taking place on so-called "lab on a chip" devices in a silicon environment. The new technology, which is published in Nature's online journal Scientific Reports, will be useful in drug development as well as disease diagnosis, researchers say.

'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.
