Roll up your screen and stow it away?
As the demand for instant, constant communication grows, so too does the urgency for more convenient portable devices -- especially computer displays that can be easily rolled up and stored or transported. A new Tel Aviv University study suggests that a novel DNA-peptide structure can be used to produce thin, transparent, and flexible screens. The research harnesses bionanotechnology to emit a full range of colors in a single pliable pixel layer.

High-tech method allows rapid imaging of functions in living brain
Researchers studying cancer and other invasive diseases rely on high-resolution imaging to see tumors and other activity deep within the body's tissues. Using a new high-speed, high-resolution imaging method, Lihong Wang, Ph.D., and his team at Washington University in St. Louis were able to see blood flow, blood oxygenation, oxygen metabolism and other functions inside a living mouse brain at faster rates than ever before.

Precocious GEM: Shape-shifting sensor can report conditions from deep in the body
Scientists working at NIST and NIH have devised and demonstrated a new, shape-shifting probe, about one-hundredth as wide as a human hair, which is capable of sensitive, high-resolution remote biological sensing that is not possible with current technology. If eventually put into widespread use, the design could have a major impact on research in medicine, chemistry, biology and engineering. Ultimately, it might be used in clinical diagnostics.

Nanoscale worms provide new route to nano-necklace structures
Researchers have developed a novel technique for crafting nanometer-scale necklaces based on tiny star-like structures threaded onto a polymeric backbone. The technique could provide a new way to produce hybrid organic-inorganic shish kebab structures from semiconducting, magnetic, ferroelectric and other materials that may afford useful nanoscale properties.

Designer's toolkit for dynamic DNA nanomachines
Researchers at the Technische Universitaet Muenchen have demonstrated a new approach to joining -- and reconfiguring -- modular DNA building units, by snapping together complementary shapes instead of zipping together strings of base pairs. This not only opens the way for practical nanomachines with moving parts, but also offers a toolkit that makes it easier to program their self-assembly. The team, led by 2015 Leibniz Prize awardee professor Hendrik Dietz, published their results in Science.

ORNL-led team demonstrates desalination with nanoporous graphene membrane
Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists led by the Department of Energy's Oak Ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene -- a carbon honeycomb one atom thick. The results are published in the March 23 advance online issue of Nature Nanotechnology.

Nanorobotic agents open the blood-brain barrier, offering hope for new brain treatments
Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. The research is important as currently 98 percent of therapeutic molecules are also unable to cross the blood-brain barrier.

Sensor cable monitors fences of all kinds and can even detect low-level drone fly-bys
Fenced-in areas, such as airports, nuclear power stations, industrial sites, or private plots of land, can now be monitored thanks to novel sensor technology that has been developed by a team of experimental physicists, led by Professor Uwe Hartmann at Saarland University. The sensors respond immediately as soon as someone tries to climb over or cut through the fence, providing information on the precise location of the security breach.

Have researchers discovered the sound of the stars?
A chance discovery by a team of researchers, including a University of York scientist, has provided experimental evidence that stars may generate sound. The study of fluids in motion -- now known as hydrodynamics -- goes back to the Egyptians, so it is not often that new discoveries are made. However when examining the interaction of an ultra-intense laser with a plasma target, the team observed something unexpected.
