Physical Review X
Penn researchers grow liquid crystal 'flowers' that can be used as lenses
A team of material scientists, chemical engineers and physicists from the University of Pennsylvania has made another advance in their effort to use liquid crystals as a medium for assembling structures. Their earlier studies produced patterns of "defects," useful disruptions in the repeating patterns found in liquid crystals, in nanoscale grids and rings. The new study adds a more complex pattern out of an even simpler template: a three-dimensional array shaped like a flower.

A micro-muscular breakthrough
Berkeley Lab researchers have demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length faster than the blink of an eye.

DNA clamp to grab cancer before it develops
As part of an international research project, a team of researchers has developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology. The results of this research is published this month in the journal ACS Nano.

Survey reveals regulatory agencies viewed as unprepared for nanotechnology
Three stakeholder groups agree that regulators are not adequately prepared to manage the risks posed by nanotechnology, according to a paper published in the peer-reviewed journal PLOS One. In a survey of nano-scientists and engineers, nano-environmental health and safety scientists, and regulators, researchers at the UCSB Center for Nanotechnology in Society and at the University of British Columbia found that those who perceive the risks posed by nanotechnology as "novel" are more likely to believe that regulators are unprepared.

UCLA researcher highlights advances in nanotechnology's fight against cancer
Among the most promising advances in the fight against cancer has been the rise of nanomedicine, the application of tiny materials and devices to detect, diagnose and treat disease. Researchers from the UCLA School of Dentistry and the National University of Singapore provide one of the most comprehensive assessments to date of research on nanomedicine-based approaches to treating cancer and offers insight into how researchers can best position nanomedicine-based cancer treatments for FDA approval.

Infrared sheds light on single protein complexes
Researchers from the nanoscience research center CIC nanoGUNE, the Freie Universität Berlin and Neaspec company employ nano-FTIR spectroscopy for label-free chemical and structural imaging of proteins with nanoscale spatial resolution and with sensitivity to single protein complexes of less than one attogram (10-18 gram). The work has been published recently in Nature Communications.

Radioactivity muddles the alphabet of DNA
Curtin University researchers have shown natural radioactivity within DNA can alter chemical compounds, providing a new pathway for genetic mutation. The research, recently published in Biochimica et Biophysica Acta-General Subjects, for the first time looked at natural radioactivity within human DNA on the atomic-scale. While radioactivity occurs naturally in our bodies as well as in every living organism across the planet, it was never before thought to affect our DNA in such a direct way.

Timing is everything in new nanotechnology for medicine, security and research
A team of researchers has created a way to control the length of time light from a luminescent nanocrystal lingers, adding a new dimension of time to color and brightness in optical detection technology. This exponentially boosts the number of different combinations that can be created and used as unique tags for biomedical screens. In addition, light emitted by the new nanocrystals far outlasts that which occurs naturally in biological systems. That difference in timing distinctly separates the signal from background noise.

Low-power tunneling transistor for high-performance devices at low voltage
A new type of transistor that could make possible fast and low-power computing devices for energy-constrained applications such as smart sensor networks, implantable medical electronics and ultra-mobile computing is feasible, according to Penn State researchers. Called a near broken-gap tunnel field effect transistor, the new device uses the quantum mechanical tunneling of electrons through an ultra-thin energy barrier to provide high current at low voltage.
