Imaging electric charge propagating along microbial nanowires
UMass Amherst physicists working with Derek Lovley and colleagues report in the current issue of Nature Nanotechnology that they've used a new imaging technique, electrostatic force microscopy, to resolve the biological debate with evidence from physics, showing that electric charges do indeed propagate along microbial nanowires just as they do in carbon nanotubes, a highly conductive man-made material.

Crystallizing the DNA nanotechnology dream
For the last 20 years, scientists have tried to design large DNA crystals with precisely prescribed depth and complex features -- a design quest just fulfilled by a team at Harvard's Wyss Institute for Biologically Inspired Engineering. The team built 32 DNA crystals with precisely-defined depth and an assortment of sophisticated three-dimensional features, an advance reported in Nature Chemistry.

Light bending material facilitates the search for new particles
Particle physicists have a hard time identifying all the elementary particles created in their particle accelerators. But now researchers at Chalmers University of Technology have designed a material that makes it much easier to distinguish the particles. The material manipulates the Cherenkov radiation from particles with high momentum so that they get a distinct light cone angle.

Engineers find a way to win in laser performance by losing
To help laser systems overcome loss, operators often pump the system with an overabundance of photons to achieve optical gain. But now engineers at Washington University in St. Louis have shown a new way to reverse or eliminate such loss by, ironically, adding loss to a laser system to actually reap energy gains. In other words, they've invented a way to win by losing.

A simple and versatile way to build 3-dimensional materials of the future
Researchers in Japan have developed a novel yet simple technique, called 'diffusion driven layer-by-layer assembly,' to construct graphene into porous three-dimensional structures for applications in devices such as batteries and supercapacitors. Their study was recently published in the journal Nature Communications.

Magnetic mirrors enable new technologies by reflecting light in uncanny ways
Scientists have demonstrated, for the first time, a new type of mirror that forgoes a familiar shiny metallic surface and instead reflects infrared light by using an unusual magnetic property of a non-metallic metamaterial. Using nanoscale antennas, researchers are able to capture and harness electromagnetic radiation in ways that have tantalizing potential in new classes of chemical sensors, solar cells, lasers, and other optoelectronic devices. The work was published in the journal Optica today.

Study reveals optimal particle size for anticancer nanomedicines
Nanomedicines consisting of nanoparticles for targeted drug delivery to specific tissues and cells offer new solutions for cancer diagnosis and therapy. In a recent study, researchers from the University of Illinois systematically evaluated the size-dependent biological profiles of three monodisperse drug-silica nanoconjugates to determine the optimum particle size for tissue penetration and tumor inhibition.

Tuning light to kill deep cancer tumors
An international group of scientists led by Gang Han, Ph.D., at the University of Massachusetts Medical School, has combined a new type of nanoparticle with an FDA-approved photodynamic therapy to effectively kill deep-set cancer cells in vivo with minimal damage to surrounding tissue and fewer side effects than chemotherapy. This promising new treatment strategy could expand the current use of photodynamic therapies to access deep-set cancer tumors.

Charged graphene gives DNA a stage to perform molecular gymnastics
When Illinois researchers investigated a method to control how DNA moves through a tiny sequencing device, they did not know they were about to witness a display of molecular gymnastics. The researchers found that a positive charge applied to a graphene nanopore speeds up DNA movement, while a negative charge stops the DNA in its tracks. However, the DNA seemed to dance across the graphene surface, pirouetting into sequence-specific shapes they had never seen.

Stanford team invents sensor that uses radio waves to detect subtle changes in pressure
The sensor is made of a special rubber layer between two strips of copper. The copper acts like radio antennas. The rubber is an insulator. Pressure squeezes the antennas infinitesimally closer, altering the electrical characteristics of the device. Radio waves beamed through the device change frequency as pressure changes, providing a way to gauge pressure wirelessly. The underlying technology could lead to prosthetic devices with an electronic sense of touch.
