Ultrafast detection of a cancer biomarker enabled by innovative nanobiodevice
Nagoya University-led researchers developed a nanobiodevice that can quickly and effectively separate microRNA, short lengths of ribonucleic acid present in bodily fluids, from mixtures of nucleic acids. The nanobiodevice contains a unique array of nanopillars that form a strong electric force under an applied electric field, allowing high-resolution separation of microRNA in less than 100 ms. Because microRNA is a biomarker for cancer, this technology may provide a simple, noninvasive approach for detecting cancer.

MRI-powered mini-robots could offer targeted treatment
Invasive surgical techniques allow physicians to effectively treat disease but can lead to sometimes serious complications and dramatically slow healing for the patient. Scientists instead want to deploy dozens, or even thousands of tiny robots to travel the body's venous system as they deliver drugs or a self-assembled interventional tool.

ORNL study examines tungsten in extreme environments to improve fusion materials
'We're trying to determine the fundamental behavior of plasma-facing materials with the goal of better understanding degradation mechanisms so we can engineer robust, new materials,' said materials scientist Chad Parish of Oak Ridge National Laboratory. He is senior author of a study in the journal Scientific Reports that explored degradation of tungsten under reactor-relevant conditions. Learning about how energetic atomic bombardment affects tungsten microscopically helps engineers improve nuclear materials.

Hexagonal boron nitride enables the fabrication of 2-dimensional electronic memories
The research group lead by Professor Mario Lanza (Soochow University, China) reports the synthesis of resistive random access memories made of graphene electrodes and multilayer hexagonal boron nitride as dielectric. The findings, published recently in Advanced Functional Materials, pave the way towards the development of advanced two-dimensional electronic memories.

Reducing conducting thin film surface roughness for electronics
As transistor dimensions within integrated circuits continue to shrink, smooth metallic lines are required to interconnect these devices. If the surfaces of these tiny metal lines aren't smooth enough, it substantially reduces their ability to conduct electrical and thermal energy -- decreasing functionality. Engineers report an advance this week in Applied Physics Letters, in modeling results that establish electrical surface treatment of conducting thin films as a physical processing method for reducing surface roughness.

Magnetic fields at the crossroads
Almost all information that exists in contemporary society is recorded in magnetic media, like hard drive disks. Researchers are studying the motion of vortex domain walls -- local regions of charge that collectively store information via their configuration -- driven by magnetic fields in ferromagnetic nanowires, which are configured in a straight line with an asymmetric Y-like branch. They discuss their work in this week's Journal of Applied Physics.

Bubble-recoil could be used to cool microchips, even in space
The bubbles that form on a heated surface create a tiny recoil when they leave it, like the kick from a gun firing blanks. Now researchers at the University of Illinois at Chicago, under funding from NASA, have shown how this miniscule force can be harnessed to mix liquid coolant around high-power microelectronics -- in space or on Earth.

Low-cost monitoring device uses light to quickly detect oil spills
Researchers have developed a simple device that can detect an oil spill in water and then pinpoint the type of oil present on the surface. The device is designed to float on the water, where it could remotely monitor a small area susceptible to pollution or track the evolution of contamination at a particular location.

Space energy technology restored to make power stations more efficient
Satellite-powering technology that was abandoned decades ago has been reinvented to potentially work with traditional power stations to help them convert heat to electricity more efficiently, meaning we would need less fossil fuel to burn for power. A new study in Nano Energy presents a prototype energy converter, which uses graphene instead of metal, making it almost seven times more efficient.

Nanoengineers 3-D print biomimetic blood vessel networks
Nanoengineers at the University of California San Diego have 3-D printed a lifelike, functional blood vessel network that could pave the way toward artificial organs and regenerative therapies. The new research addresses one of the biggest challenges in tissue engineering: creating lifelike tissues and organs with functioning vasculature -- networks of blood vessels that can transport blood, nutrients, waste and other biological materials -- and do so safely when implanted inside the body.

A SOI wafer is a suitable substrate for gallium nitride crystals
In cooperation with Okmetic Oy and the Polish ITME, researchers at Aalto University have studied the application of SOI (Silicon On Insulator) wafers, which are used as a platform for manufacturing different microelectronics components, as a substrate for producing gallium nitride crystals. The researchers compared the characteristics of gallium nitride (GaN) layers grown on SOI wafers to those grown on silicon substrates more commonly used for the process.

Most complex nanoparticle crystal ever made by design
The most complex crystal designed and built from nanoparticles has been reported by researchers at Northwestern University and the University of Michigan. The work demonstrates that some of nature's most complicated structures can be deliberately assembled if researchers can control the shapes of the particles and the way they connect using DNA. Potential applications of the cage-like structures, called clathrates, include controlling light, capturing pollutants and delivering therapeutics. New types of lenses, lasers and even Star Trek-like cloaking materials are possible.

JILA team discovers many new twists in protein folding
Biophysicists at JILA have measured protein folding in more detail than ever before, revealing behavior that is surprisingly more complex than previously known. The results suggest that, until now, much about protein behavior has been hidden to science -- happening on faster timescales and with finer changes in structure than conventional methods could detect.
