Physical Review X
Nanoscale one-way-street for light
If light is able to propagate from left to right, the opposite direction is usually allowed as well. Researchers at TU Wien have developed a new device for breaking this rule. A one-way-street for light can now be used for optical chips and may thus become important for optical signal processing.

Better catalysts for green energy
A new study, just published in Nature Materials, provides a detailed account of how to control the electron charge of nanoparticles of platinum, an important catalyst in fuel cells, to maximize the efficiency of the process. The study is the result of an intense international collaboration involving SISSA and CNR-IOM of Trieste, the University of Barcelona, ELETTRA Sincrotrone Trieste, Friedrich-Alexander Universität Erlangen-Nürnberg in Germany and Univerzita Karlova of Prague.

How multiple sclerosis can be triggered by brain cell death
Multiple sclerosis may be triggered by the death of brain cells that make the insulation around nerve fibers, a surprising new view of the disease reported in a study. A specially developed nanoparticle prevented MS even after the death of those brain cells, an experiment in the study showed. The nanoparticles are being developed for clinical trials that could lead to new treatments -- without the side effects of current therapies.

Diagnostics with birefringence
ETH researchers led by Raffaele Mezzenga have developed a new diagnostic method. It is based on Birefringence, the ability of substances to change the polarization state of light. With this method, doctors around the world can easily, rapidly and reliably detect malaria, Ebola or HIV to name only a few.

Shaking the nanomaterials out
Nano implies small -- and that's great for use in medical devices, beauty products and smartphones -- but it's also a problem. All these tiny particles get into our water and are difficult to remove. Now, Michigan Tech researchers Yoke Khin Yap and Dongyang Zhang have a novel and very simple way to take the nanomaterials out.

Physics of wrapping miniature droplets takes cue from street foods
Professor Joseph Paulsen researches soft condensed matter physics or, "the study of things that are squishy," he explains. This area of research focuses on substances that can be easily bent or deformed, such as liquids, foams, and gels. In this case, Paulsen and colleagues investigated the way very thin elastic sheets wrap droplets of water.

Nanotech drug delivery shows promise for improved melanoma treatment
Researchers have developed a new three-drug delivery system for cancer treatment, especially metastatic melanoma, the deadliest form of skin cancer -- and shown that the system may have particular value with cancers like this that often spread through the lymphatic system. It may offer a novel therapeutic option for more effective cancer treatment.

Seeing viruses in a new light
If researchers can understand how viruses assemble, they may be able to design drugs that prevent viruses from forming in the first place. Unfortunately, how exactly viruses self-assemble has long remained a mystery because it happens very quickly and at such small length-scales. Now, there is a system to track nanometer-sized viruses at sub-millisecond time scales. The method is the first step towards tracking individual proteins and genomic molecules at high speeds as they assemble to create a virus.

The world's tiniest temperature sensor is powered by radio waves
Researchers at Eindhoven University of Technology have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are part of the sensor's wireless network. This means that the sensor needs not even a single wire, nor a battery that would have to be replaced. The arrival of such sensors is an important development on route towards smart buildings, for instance.

Measuring nanoscale features with fractions of light
National Institute of Standards and Technology (NIST) researchers are seeing the light, but in an altogether different way. And how they are doing it just might be the semiconductor industry's ticket for extending its use of optical microscopes to measure computer chip features that are approaching 10 nanometers, tiny fractions of the wavelength of light. They report measurements of lines as thin as 16 nanometers wide on a SEMATECH-fabricated wafer were accurate to one nanometer.

'Nanobombs' might deliver agents that alter gene activity in cancer stem cells
Researchers at The Ohio State University Comprehensive Cancer Center -- Arthur G. James Cancer Hospital and Richard J. Solove Research Institute have developed nanoparticles that swell and burst when exposed to near-infrared laser light. Such 'nanobombs' might overcome a biological barrier that has blocked development of agents that work by altering the activity -- the expression -- of genes in cancer cells. The agents might kill cancer cells outright or stall their growth.
