Magnetic vortices in nanodisks reveal information
(Helmholtz-Zentrum Dresden-Rossendorf) Researchers at the Helmholtz-Zentrum Dresden-Rossendorf and Forschungszentrum Jlich together with a colleague at the French CNRS in Strasbourg have found a new way to electrically read out the orientation of magnetic vortices in nanodisks. Their method relies on measuring characteristic microwaves emanating from the vortices. Knowledge about these signals could be used for constructing extremely small components for novel memory technology or wireless data transmission. The results are published in Nature Communications.

New nanodevice defeats drug resistance
(Massachusetts Institute of Technology) A nanodevice from MIT researchers can disable drug-resistance genes, then release cancer drugs.

Glass coating improves battery performance
(University of California - Riverside) Researchers in the Bourns College of Engineering at the University of California, Riverside have investigated a strategy to prevent this 'polysulfide shuttling' phenomenon by creating nano-sized sulfur particles, and coating them in silica, otherwise known as glass.

Colon + septic tank = unique, at times stinky, study
(University of California - Riverside) What do a human colon, septic tank, copper nanoparticles and zebrafish have in common? They were the key components used by researchers at the University of California, Riverside and UCLA to study the impact copper nanoparticles, which are found in everything from paint to cosmetics, have on organisms inadvertently exposed to them.

Pens filled with high-tech inks for do-it-yourself sensors
(University of California - San Diego) A new simple tool developed by nanoengineers at the University of California, San Diego, is opening the door to an era when anyone will be able to build sensors, anywhere, including physicians in the clinic, patients in their home and soldiers in the field. The team from the University of California, San Diego, developed high-tech inks that react with several chemicals, including glucose. They tested the sensors to measure glucose and pollution.

Smart crystallization
(International Union of Crystallography) The first semi-liquid, non-protein nucleating agent for automated protein crystallization trials is described. This 'smart material' is demonstrated to induce crystal growth and will provide a simple, cost-effective tool for scientists in academia and industry.

International research partnership tricks the light fantastic
(University of Cincinnati) A manipulation of light through tiny technology could lead to big benefits for everything from TVs to microscopes.

Researchers turn unzipped nanotubes into possible alternative for platinum
(Rice University) Aerogels made of graphene nanoribbons and modified with boron and nitrogen are more efficient catalysts for fuel cells and air-metal batteries than expensive platinum is, according to researchers at Rice University.

Breakthrough in OLED technology
(American Institute of Physics) A new study from a team of researchers in California and Japan shows that organic light emitting diodes made with finely patterned structures can produce bright, low-power light sources, a key step toward making organic lasers. The results are reported in a paper appearing this week on the cover of the journal Applied Physics Letters, from AIP Publishing.

Untangling DNA with a droplet of water, a pipet and a polymer
(KU Leuven) Researchers have long sought an efficient way to untangle DNA to study its structure -- neatly unraveled and straightened out -- under a microscope. Now, researchers at KU Leuven have devised a simple and effective solution: they inject genetic material into a droplet of water and use a pipet tip to drag it over a glass plate covered with a sticky polymer.
