A new type of monitoring provides information about the life of bacteria in microdroplets
In the future, it will be possible to carry out tests of new drugs on bacteria much more efficiently using microfluidic devices, since each of the hundreds and thousands of droplets moving through the microchannels can act as separate incubators. So far, however, there has been no quick or accurate method of assessing the oxygen conditions in individual microdroplets. This key obstacle has been overcome at the Institute of Physical Chemistry of the Polish Academy of Sciences.

First look inside nanoscale catalysts shows 'defects' are useful
Peering for the first time into the workings of tiny chemical catalysts, scientists observed that the 'defective' structure on their edges enhances their reactivity and effectiveness. This finding that could lead to the design of improved catalysts that make industrial chemical processes greener, by decreasing the amount of energy needed for chemical reactions, and preventing the formation of unwanted and potentially hazardous products.

New laser based on unusual physics phenomenon could improve telecommunications, computing
Researchers at the University of California San Diego have demonstrated the world's first laser based on an unconventional wave physics phenomenon called bound states in the continuum. The technology could revolutionize the development of surface lasers, making them more compact and energy-efficient for communications and computing applications. The new BIC lasers could also be developed as high-power lasers for industrial and defense applications.

3-D printing and nanotechnology, a mighty alliance to detect toxic liquids
Carbon nanotubes have made headlines in scientific journals for a long time, as has 3-D printing. But when both combine with the right polymer, in this case a thermoplastic, something special occurs: electrical conductivity increases and makes it possible to monitor liquids in real time. This is a huge success for Polytechnique Montréal.

Neurons modulate the growth of blood vessels
A team of researchers at Karlsruhe Institute of Technology shake at the foundations of a dogma of cell biology. By detailed series of experiments, they proved that blood vessel growth is modulated by neurons and not, as assumed so far, through a control mechanism of the vessel cells among each other. The results are groundbreaking for research into and treatment of vascular diseases, tumors, and neurodegenerative diseases. The study will be published in the prestigious journal Nature Communications.

Zeroing in on the true nature of fluids within nanocapillaries
Shrinking the investigation of objects to the nanometer scale often reveals new properties of matter that have no equivalent for their bulk analysis. This phenomenon is motivating studies of nanomaterials which can reveal fascinating new phenomena. It inspired researchers to explore the extent of knowledge about fundamental properties of fluids, which demands reconsideration with the increasing use of fluids in the decreasing sizes of new devices, where their flow is confined into ever-smaller capillary tubes.

Physicists solve decades-old scientific mystery of negative differential resistance
With a storied history that includes more than a half-century of research, a Nobel Prize, and multiple attempts at practical applications, the story of negative differential resistance -- or NDR -- reads like a scientific mystery, a mystery that University of Alberta physicists have at last succeeded in unraveling.

Telecommunications light amplifier could strengthen integrity of transmitted data
Imagine a dim light which is insufficiently bright enough to illuminate a room. An amplifier for such a light would increase the brightness by increasing the number of photons emitted. Photonics researchers have created such a high gain optical amplifier that is compact enough to be placed on a chip. The developed amplifier would help to efficiently increase the power of the transmitted light before it is completely depleted through optical losses.

Nanowire 'inks' enable paper-based printable electronics
Thin films made from silver nanowires are 4,000 times more conductive than films made from other nanoparticle shapes, like spheres or microflakes, says a new study by Duke University researchers. The results indicate that conductive 'inks' made from silver nanowires may create functioning electronic circuits without applying high temperatures, enabling printable electronics on heat-sensitive materials like paper or plastic.

Random access memory on a low energy diet
Memory chips are among the most basic components in computers. The random access memory is where processors temporarily store their data, which is a crucial function. Researchers from Dresden and Basel have now managed to lay the foundation for a new memory chip concept. It has the potential to use considerably less energy than the chips produced to date -- this is important not only for mobile applications but also for big data computing centers (Nature Communications).

A new direction in ophthalmic development: Nanoparticle drug delivery systems
Most ophthalmic diseases are usually treated with topically administered drug formulations (e.g. eye drops). Their main disadvantage is the short time of contact with the eye, which leads to a low degree of absorption of the active substance (less than 5 percent of the drug administered). This requires frequent instillation, which usually leads to a high systemic exposure.

Researchers produced nitrogen doped bimodal cellular structure activated carbon
New monolithic nitrogen-containing microporous cellular activated carbon was successfully prepared from phenol-urea-formaldehyde (PUF) organic foam for CO2 and H2 adsorption. The macroporosity corresponded to the connected network of cells with diameters ranging from 100 to 600 μm, and the pinholes in the cell walls had diameters ranging from 1 to 2 μm. The micro/mesoporosity is located at the inner surface of the cells.

Miniscule amounts of impurities in vacuum greatly affecting OLED lifetime
Reproducibility is a necessity for science but has often eluded researchers studying the lifetime of organic light-emitting diodes (OLEDs). Recent research from Japan sheds new light on why: impurities present in the vacuum chamber during fabrication but in amounts so small that they are easily overlooked.
