Measuring molecules with the naked eye
A new "lab on a chip" reveals the presence of ultra-low concentrations of a target molecule to the naked eye. This model for diagnostic testing could mean point-of-care results displayed visually for diseases that involve very subtle shifts in the bloodstream.

A new take on the Midas touch -- changing the color of gold
Red gold, green gold -- a ground-breaking initiative has found a way of changing the color of the world's most iconic precious metal. A University of Southampton team have discovered that by embossing tiny raised or indented patterns onto the metal's surface they can change the way it absorbs and reflects light -- ensuring our eyes don't see it as "golden" in color at all.

Nanofibrillar cellulose film to ease performing medical tests
Researchers at Aalto University in Finland have succeeded in developing a durable and affordable nanofibrillar cellulose film platform to support medical testing. New environmentally friendly, reliable nanofibrillar cellulose platforms are more diverse than plastic films. New film can be made, for instance, hydrophobic, hydrophilic and the electric charge can be changed. This will enhance the possibility of conducting thousands of different medical tests at home or in physicians' receptions instead of waiting for results from laboratories.

Manufacturing complex 3-D metallic structures at nanoscale made possible
The fabrication of many objects, machines, and devices around us rely on the controlled deformation of metals by industrial processes such as bending, shearing, and stamping. But is this technology transferrable to nanoscale? Scientists from Aalto University in Finland and the University of Washington in the US have just demonstrated this to be possible. By combining ion processing and nanolithography they have managed to create complex three-dimensional structures at nanoscale.

Developing the next generation of microsensors
Setting the stage for a new class of motional sensors, researchers at Caltech and the University of Rochester have developed a new ultrasensitive, microchip-scale accelerometer that uses laser light to measure displacement. Beyond consumer electronics, such sensors could help with oil and gas exploration deep within the earth, could improve the stabilization systems of fighter jets, and could even be used in some biomedical applications where more traditional sensors cannot operate.

New cobalt-graphene catalyst could challenge platinum for use in fuel cells
There's a new contender in the race to find an inexpensive alternative to platinum catalysts for use in hydrogen fuel cells. Brown University chemist Shouheng Sun and his students have developed a new material -- a graphene sheet covered by cobalt and cobalt-oxide nanoparticles -- that can catalyze the oxygen reduction reaction nearly as well as platinum does and is substantially more durable.

Effort to mass-produce flexible nanoscale electronics
Case Western Reserve University researchers have won a $1.2 million grant to develop technology for mass-producing flexible electronic devices at a whole new level of small. As they're devising new tools and techniques to make nanowires and devices, they're creating ways to build them in flexible materials and package the electronics in waterproofing layers of durable plastics. The technology may be used to make implants that cause less damage to foldable electronics as thin as a sheet of plastic wrap.

Science: Quantum oscillator responds to pressure
In the far future, superconducting quantum bits might serve as components of high-performance computers. Today already do they help better understand the structure of solids, as is reported by researchers of Karlsruhe Institute of Technology in the Science magazine. By means of Josephson junctions, they measured the oscillations of individual atoms "tunneling" between two positions. This means that the atoms oscillated quantum mechanically. Deformation of the specimen even changed the frequency (DOI: 10.1126/science.1226487).
