Graphene microphone outperforms traditional nickel and offers ultrasonic reach
(Institute of Physics) Scientists have developed a graphene based microphone nearly 32 times more sensitive than microphones of standard nickel-based construction.The researchers created a vibrating membrane -- the part of a condenser microphone which converts the sound to a current -- from graphene, and were able to show up to 15 dB higher sensitivity compared to a commercial microphone, at frequencies up to 11 kHz.

Stanford technology makes metal wires on solar cells nearly invisible to light
(Stanford University) Stanford University scientists have discovered how to make the electrical wiring on top of solar cells nearly invisible to incoming light. The new design, which uses silicon nanopillars to hide the wires, could dramatically boost solar-cell efficiency.

Penn researchers discover why E. coli move faster in syrup-like fluids than in water
(University of Pennsylvania) Swimming in a pool of syrup would be difficult for most people, but for bacteria like E. coli, it's easier than swimming in water. Scientists have known for decades that these cells move faster and farther in viscoelastic fluids, such as the saliva, mucus, and other bodily fluids they are likely to call home, but didn't understand why. New findings could inform disease models and treatments, or even help design microscopic swimming robots.

Nanoparticles simplify DNA identification and quantification
(Universitat Autonoma de Barcelona) The article was led by ICN2 researchers in colaboration with UAB researchers, within the POC4PETS European Project, aimed to improving the speed and accuracy of current diagnostics for veterinary pathogens.

A new form of real gold, almost as light as air
(ETH Zurich) Researchers at ETH Zurich have created a new type of foam made of real gold. It is the lightest form ever produced of the precious metal: a thousand times lighter than its conventional form and yet it is nearly impossible to tell the difference with the naked eye. There are many possible applications.

Stanford faculty awarded $2.1 million for promising energy research
(Stanford University) The Precourt Institute for Energy and the TomKat Center for Sustainable Energy at Stanford University have awarded 12 faculty seed grants totaling $2.1 million for groundbreaking research on clean energy.

AIAA honors UTA's Frank Lewis with 2016 Intelligent Systems Award
(University of Texas at Arlington) The American Institute of Aeronautics and Astronautics will honor professor Frank Lewis, head of the University of Texas at Arlington's Advanced Controls and Sensors Group, with the society's 2016 Intelligent Systems Award in recognition of his work to advance the capabilities of autonomous aircraft systems.

MIT mathematicians identify limits to heat flow at the nanoscale
(Massachusetts Institute of Technology) MIT mathematicians have derived a formula for determining the maximum amount of heat exchanged between two objects separated by distances shorter than the width of a single hair. For any two objects situated mere nanometers apart, the formula can be used to calculate the most heat one body may transmit to another, based on two parameters: what the objects are made of, and how far apart they are.

Inkjet hologram printing now possible
(ITMO University) Vivid holographic images and text can now be produced by means of an ordinary inkjet printer. This new method, developed by a team of scientists from ITMO University in Saint Petersburg, is expected to significantly reduce the cost and time needed to create the so-called rainbow holograms, commonly used for security purposes -- to protect valuable items, such as credit cards and paper currency, from piracy and falsification.

Stretch the new flex for programmable rubber keyboard
(Institute of Physics) Scientists at the University of Auckland have developed a soft, flexible, stretchable keyboard using a type of rubber known as a dielectric elastomer.The results are reported today, Nov. 25, 2015, in the journal Smart Materials and Structures.
