Diamond-based resonators might become highly sensitive detectors
A comprehensive study of acoustic waves in piezoelectric layered structures has led to a number of interesting discoveries. In particular, the researchers have come up with a possible way to reduce the effect of spurious peaks -- an undesirable phenomenon which occurs while studying a frequency response in such materials.

Self-assembling icosahedral protein designed
Researchers have designed and produced a self-assembling protein shell shaped like an icosahedron -- similar to those that encapsulate viruses. The achievement may open new avenues for engineering cargo-containing nano-cages to package and deliver drugs and vaccines directly into cells, or building small reactors to catalyze biochemical reactions. The shell is also amenable to genetic fusion, such as the addition of fluorescent proteins.

Tailored DNA shifts electrons into the 'fast lane'
DNA molecules don't just code our genetic instructions. They also have the unique ability to conduct electricity and self-assemble into well-defined shapes, making them potential candidates for building low-cost nanoelectronic devices. A study by a team of researchers from Duke University and Arizona State University shows how DNA sequences can be manipulated to turn these ribbon-shaped molecules into electron 'highways,' allowing electricity to flow more easily through the strand.

10,000 windows onto biomolecular information processing
A Franco-Japanese research group at the University of Tokyo has developed a new 'brute force' technique to test thousands of biochemical reactions at once and quickly home in on the range of conditions where they work best. Until now, optimizing such biomolecular systems, which can be applied for example to diagnostics, would have required months or years of trial and error experiments, but with this new technique that could be shortened to days.

Scientists engineer tunable DNA for electronics applications
A team led by ASU Biodesign Institute researcher Nongjian (N.J.) Tao and Duke theorist David Beratan has been able to understand and manipulate DNA to more finely tune the flow of electricity through it. The key findings, which can make DNA behave in different ways -- cajoling electrons to smoothly flow like electricity through a metal wire, or hopping electrons about like the semiconductors materials that power our computers and cell phones, paves the way for an exciting new avenue of research advancements.

Artificial synapse rivals biological ones in energy consumption
POSTECH researchers have succeeded in fabricating an organic nanofiber electronic device that emulates not only the important working principles and energy consumption of biological synapses but also the morphology. They recently published their findings in Science Advances, a new sister journal of Science.

Marrying superconductors, lasers, and Bose-Einstein condensates
As superconductors, lasers, and Bose-Einstein condensates all share a common feature, it has been expected that it should be able to see these features at the same time. A recent experiment in a global collaborative effort with teams from Japan, the United States, and Germany have observed for the first time experimental indication that this expectation is true.

A new trick for controlling emission direction in microlasers
Researchers at Washington University in St. Louis have found a way to give photons, or light packets, their marching orders. The researchers have capitalized on the largesse of an energy state in an optical field to make photons in their lasing system travel in a consistent mode, either clockwise or counterclockwise.

Researchers open hairy new chapter in 3-D printing
Researchers in MIT's Media Lab have found a way to bypass a major design step in 3-D printing, to quickly and efficiently model and print thousands of hair-like structures. Instead of using conventional computer-aided design (CAD) software to draw thousands of individual hairs on a computer the team built a new software platform, called 'Cilllia,' that lets users define the angle, thickness, density, and height of thousands of hairs, in just a few minutes.

Droplets finally all the same size -- in a nanodroplet library
A single microdroplet is really not very large and certainly does not look like something you can do a lot with. However, a simple device, constructed at the IPC PAS in Warsaw, Poland, can split the microdroplet into a collection of equally sized nanodroplets. From now on, the valuable chemicals contained in a single microdroplet can be the starting point of even hundreds of experiments -- or they can be archived in the form of nanodroplet libraries.

Drum beats from a one atom thick graphite membrane
Researchers at TIFR, Mumbai, demonstrate the ability to electrically manipulate the vibrations of a drum, of nanometer scale thickness, a million times smaller than that of human hair. These drums vibrate a whopping 100 million times a second -- which cannot be heard by the ear but can be sensed using small circuits. This can be used to make new kinds of mass sensors. Also, new aspects of fundamental physics could be probed in the future.
