Can the brain feel it? The world's smallest extracellular needle-electrodes
A research team from Toyohashi University of Technology developed the world's smallest 5-μm-diameter low-invasive needle electrodes, which are assembled on 1 x 1 mm2 blocks. Surprisingly, high quality neuronal signals from a mouse's cortex were stably recorded for a long period. Their new electrode device reduces the total invasiveness to brain tissue in vivo and realizes stable neural recordings, thus enhancing opportunities for needle-electrode device technology in neurophysiology.

The quantum sniffer dog
A new kind of sensor to identify gases has been developed at TU Wien (Vienna), based on quantum-cascade-technology. The sensor can emit laser light which is sent through the gas and reflected back into the sensor, where the same structure can act as a light detector.

Flexible optical design method for superconducting nanowire single-photon detectors
The National Institute of Information and Communications Technology has succeeded in the development of flexible optical design method for superconducting nanowire single-photon detectors (SSPDs or SNSPDs). This technique enables SSPDs with a broadband high detection efficiency reject a specific wavelength, and is effective for multidisciplinary applications in fields such as the quantum cryptography, fluorescence spectroscopy, and remote sensing that require high efficiency over a precise spectral range and strong signal rejection at other wavelengths.

New method increases energy density in lithium batteries
Columbia Engineering Professor Yuan Yang has developed a new method to increase the energy density of lithium batteries. He has built a trilayer structure that is stable even in ambient air, which makes the battery both longer lasting and cheaper to manufacture. The work, which may improve the energy density of lithium batteries by 10-30%, is published online today in Nano Letters.

3-D-printed organ-on-a-chip with integrated sensors
Researchers have made the first entirely 3-D-printed organ-on-a-chip with integrated sensing. Built by a fully automated, digital manufacturing process, the 3-D-printed heart-on-a-chip can be quickly fabricated and customized. This new approach to manufacturing may one day allow researchers to rapidly design organs-on-chips, also known as microphysiological systems, that match the properties of a specific disease or even an individual patient's cells.

A novel noninvasive imaging probe for fast and sensitive detection of cancer
The ultimate goal of cancer diagnostics is to develop sensitive imaging techniques for reliable detection of tumor malignancy in the body. Scientists at Tokyo Institute of Technology have come close to achieving this goal by developing an injectable imaging probe that can specifically detect solid tumors based on the activity of hypoxia-inducible factor regulated by the ubiquitin-proteasome system.

Development of highly active and stable ammonia synthesis catalyst under low temperatures
Profs. Hosono, Hara, Kitano, Abe and Dr. Inoue found that ruthenium nanoparticles immobilized on calcium amide (Ca(NH2)2) function as an efficient catalyst for ammonia synthesis at 300°C and the catalytic activity is more than 10 times higher than that of the highest performance Ru catalysts reported so far. In addition, 3% Ba-doped Ca(NH2)2 supported Ru catalyst exhibited excellent stability during reaction for 700 h (almost 1 month).

Tiny gold particles could be the key to developing a treatment for pancreatic cancer
A diagnosis of pancreatic cancer is often a death sentence because chemotherapy and radiation have little impact on the disease. In the US this year, some 53,000 new cases will be diagnosed, and 42,000 patients will die of the disease, according to the National Institutes of Health. But research now being reported in ACS Nano could eventually lead to a new type of treatment based on gold nanoparticles.

Exploring defects in nanoscale devices for possible quantum computing applications
Researchers at Tokyo Institute of Technology in collaboration with the University of Cambridge have studied the interaction between microwave fields and electronic defect states inside the oxide layer of field-effect transistors at cryogenic temperatures. It has been found that the physics of such defect states are consistent with driven two-level systems possessing long coherence times, and that their induced dynamics can be coherently and independently controlled.

Working under pressure: Diamond micro-anvils with huge pressures will create new materials
University of Alabama at Birmingham researchers will use pressures greater than those found at the center of the Earth to potentially create as yet unknown new materials. In the natural world, such immense forces deep underground can turn carbon into diamonds, or volcanic ash into slate. The ability to produce these pressures depends on tiny nanocrystalline-diamond anvils built in a UAB clean room manufacturing facility.

Peptides vs. superbugs
Several peptides have an antibacterial effect -- but they are broken down in the human body too quickly to exert this effect. Empa researchers have now succeeded in encasing peptides in a protective coat, which could prolong their life in the human body. This is an important breakthrough because peptides are considered to be a possible solution in the fight against antibiotic-resistant bacteria.
