The taming of magnetic vortices
Magnetic vortex structures, so-called skyrmions, could in future store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, a team of physicists succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and developed a unified theoretical description of their behavior. This lays the foundation for future electronic components with purpose-designed properties.

Magnetic vortices in nanodisks reveal information
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf and Forschungszentrum Jülich 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.

The rub with friction
In a new paper in Nature Materials, Brandeis University professor Zvonomir Dogic and his lab explored friction at the microscopic level. They discovered that the force generating friction is much stronger than previously thought. The discovery is an important step toward understanding the physics of the cellular and molecular world and designing the next generation of microscopic and nanotechnologies.

Pens filled with high-tech inks for do-it-yourself sensors
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.

Untangling DNA with a droplet of water, a pipet and a polymer
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.

CWRU researchers bring clean energy a step closer
Researchers at Case Western Reserve University have made an inexpensive metal-free catalyst that performs as well as costly metal catalysts at speeding the oxygen reduction reaction in an acidic fuel cell, and is more durable. The catalyst is made of sheets of nitrogen-doped graphene that provides great surface area, carbon nanotubes that enhance conductivity, and carbon black particles that separate the layers allowing the electrolyte and oxygen to flow freely, which greatly increased performance and efficiency.

Moving molecule writes letters
High performance materials for gas storage, thermal insulators or nanomachines need a thorough understanding of the behavior of the material down to the molecular level. Thermodynamics, which have been developed two hundred years ago to increase the efficiency of steam engines, typically observes and averages over a large number of molecules. Now a team of scientists has developed a methodology, to investigate the equilibrium thermodynamics of single molecules.

The building blocks of the future defy logic
Wake up in the morning and stretch; your midsection narrows. Pull on a rubber band and it becomes thinner. One might assume that materials will always stretch and thin. Wrong. Thanks to their peculiar internal geometry, auxetic materials grow wider when stretched. After confounding scientists for decades, University of Malta researchers are now developing mathematical models to explain the unusual behavior of these logic-defying materials, unlocking applications from better skin grafts to new smart materials.

Study shows troubling rise in use of animals in experiments
Despite industry claims of reduced animal use as well as federal laws and policies aimed at reducing the use of animals, the number of animals used in leading US laboratories increased a staggering 73 percent from 1997 to 2012, according to a new study by PETA to be published Feb. 25 11:30 p.m. UK time in the peer-reviewed Journal of Medical Ethics, the world's leading bioethics journal.

Magnetic nanoparticles enhance performance of solar cells
Magnetic nanoparticles can increase the performance of solar cells made from polymers -- provided the mix is right. This is the result of an X-ray study at DESY's synchrotron radiation source PETRA III. Adding about 1 percent of such nanoparticles by weight makes the solar cells more efficient, according to the findings published in the journal Advanced Energy Materials.

Cutting-edge technology optimizes cancer therapy with nanomedicine drug combinations
Designing optimized combination therapies for cancer is remarkably difficult due to the infinite possible drug dose ratios and variable patient-specific response to treatment. In a landmark advance for personalized medicine, University of California Los Angeles bioengineers have developed a novel technology that, for the first time, overcomes these challenges. By assessing phenotype, or physical biological traits as they respond to chemotherapy to drive a powerful analytics platform, the most effective and safe drug combinations possible can be systematically designed.

Ultra-thin nanowires can trap electron 'twisters' that disrupt superconductors
Superconductor materials carry electric current without resistance, but this valuable trait can be crippled by tiny tornado-like formations of electrons called vortices. To keep supercurrents flowing, scientists have figured out how to constrain troublesome vortices by trapping them within extremely short, ultra-thin nanowires.
