Multiple bends won’t crack this lightweight, paper-like, flexible ceramic
Posted by Klaus Baldauf in categories: electronics, materials, wearables
A flexible, paper-like ceramic material has been created that promises to provide an inexpensive, fireproof, non-conductive base for a whole range of new and innovative electronic devices (Credit: Eurakite). View gallery (4 images)
Materials to make hard-wearing, bendable non-conducting substrates for wearables and other flexible electronics are essential for the next generation of integrated devices. In this vein, researchers at the University of Twente have reformulated ceramic materials so that they have the flexibility of paper and the lightness of a polymer, but still retain exceptional high-temperature resistance. The new material has been dubbed flexiramics.

Research on largest network of cortical neurons to date
Posted by Karen Hurst in categories: biotech/medical, electronics, engineering, neuroscience
Awesome!
Even the simplest networks of neurons in the brain are composed of millions of connections, and examining these vast networks is critical to understanding how the brain works. An international team of researchers, led by R. Clay Reid, Wei Chung Allen Lee and Vincent Bonin from the Allen Institute for Brain Science, Harvard Medical School and Neuro-Electronics Research Flanders (NERF), respectively, has published the largest network to date of connections between neurons in the cortex, where high-level processing occurs, and have revealed several crucial elements of how networks in the brain are organized. The results are published in the journal Nature.
“This is a culmination of a research program that began almost ten years ago. Brain networks are too large and complex to understand piecemeal, so we used high-throughput techniques to collect huge data sets of brain activity and brain wiring,” says R. Clay Reid, M.D., Ph.D., Senior Investigator at the Allen Institute for Brain Science. “But we are finding that the effort is absolutely worthwhile and that we are learning a tremendous amount about the structure of networks in the brain, and ultimately how the brain’s structure is linked to its function.”

Monitoring Fugitive Methane Emissions Utilizing Advanced Small Unmanned Aerial Sensor Technology Currently Under Development Through ARPA-E
Posted by Karen Hurst in categories: electronics, robotics/AI, transportation
HOUSTON, March 23, 2016 /PRNewswire/ — Heath Consultants Incorporated (Heath) in collaboration with Physical Sciences Inc. (PSI), is adapting the industry-leading laser-based Remote Methane Leak Detector (RMLD®) for mounting on the InstantEye®, PSI’s two-foot-wide quadrotor Unmanned Aerial Vehicle featuring highly advanced autonomy and all-weather operation. This technology combination, known as the RMLD® Sentry, will implement self-directed flight patterns to continuously monitor, locate, and quantify volumetric leak rates of methane, a potent greenhouse gas, from natural gas production sites.

DNA Devices Perform Bio-Analytical Chemistry Inside Live Cells
Posted by Karen Hurst in categories: biotech/medical, chemistry, electronics, nanotechnology
Last summer, the team reported another achievement: the development of a DNA nanosensor that can measure the physiological concentration of chloride with a high degree of accuracy.
“Yamuna Krishnan is one of the leading practitioners of biologically oriented DNA nanotechnology,” said Nadrian Seeman, the father of the field and the Margaret and Herman Sokol Professor of Chemistry at New York University. “These types of intracellular sensors are unique to my knowledge, and represent a major advance for the field of DNA nanotechnology.”

Mapping Brain’s Cortical Columns To Develop Innovative Brain-Computer Interfaces
Posted by Karen Hurst in categories: computing, electronics, neuroscience
The EU-funded COLUMNARCODECRACKING project has successfully used ultra-high fMRI scanners to map cortical columns, a process that opens the door to exciting new applications, such as brain-computer interfaces.
Cortical columnar-level fMRI has already contributed and will further contribute to a deeper understanding of how the brain and mind work by zooming into the fine-grained functional organization within specialized brain areas.
By focussing on this, the project has stimulated a new research line of ‘mesoscopic’ brain imaging that is gaining increasing momentum in the field of human cognitive and computational neuroscience. This new field complements conventional macroscopic brain imaging that measures activity in brain areas and large-scale networks.
