Scientific Reports
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.

Together, nanotechnology and genetic interference may tackle 'untreatable' brain tumors
There are no effective available treatments for sufferers of Glioblastoma multiforme, the most aggressive and devastating form of brain tumor. Now a new Tel Aviv University study may offer hope to the tens of thousands diagnosed with gliomas every year, using a nanomedical treatment first engineered to tackle ovarian cancer tumors.

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.

Detecting defects at the nanoscale will profit solar panel production
Research at the University of Huddersfield will lead to major efficiency gains and cost savings in the manufacture of flexible solar panels. The project is called NanoMend and is funded by the EU's Framework Seven Research Programme. The goal is to develop new technologies for the detection, cleaning and repair of micro and nanoscale defects in thin films that are vital in products such as printed electronics and solar panels.

Optical nanoantennas set the stage for a NEMS lab-on-a-chip revolution
Newly developed tiny antennas, likened to spotlights on the nanoscale, offer the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer, according to the Australian scientists who created them. In the Journal of Applied Physics, they describe these and other envisioned applications for their nanocubes in 'laboratories-on-a-chip.'

Penn researchers develop new technique for making molybdenum disulfide
University of Pennsylvania researchers have made an advance in manufacturing molybdenum disulphide, a 2-D material that could compete with graphene for replacing silicon in next-generation electronics. By growing flakes of the material around 'seeds' of molybdenum oxide, they have made it easier to control the size, thickness and location of the material.

Bar-Ilan U. researcher first to observe 'god particle' analogue in superconductors
The Nobel Prize-winning discovery of the Higgs boson -- the 'God particle' believed responsible for all the mass in the universe -- took place in 2012 at CERN's Large Hadron Collider. The first hint of Higgs was inspired by the study of superconductors -- a special class of metals that, when cooled to very low temperatures, allow electrons to move without resistance. Now, a research team led by Israeli and German physicists has reported the first-ever observations of the Higgs mode in superconducting materials.

Monitoring the real-time deformation of carbon nanocoils under axial loading
Tensile tests were performed on nine carbon nanocoils using a focused-ion-beam technique. An individual CNC was picked up using -- an FIB, and a CNC bridge formed between a probe and the spring-table?substrate. Real-time observations of the CNC elongation and subsequent -- fracture under prolonged stretching enabled us to estimate the elastic -- limit, the spring constant, the shear modulus, and the ultimate strength -- of each CNC and their mean values.
