UT Dallas scientists have constructed novel fibers by wrapping sheets of tiny carbon nanotubes to form a sheath around a long rubber core. This illustration shows complex two-dimensional buckling, shown in yellow, of the carbon nanotube sheath/rubber-core fiber. The buckling results in a conductive fiber with super elasticity and novel electronic properties. (credit: UT Dallas Alan G. MacDiarmid Nanotech Institute)

An international research team based at The University of Texas at Dallas has made electrically conducting fibers that can be reversibly stretched to more than 14 times their initial length and whose electrical conductivity increases 200-fold when stretched.

SSDs and other flash memory devices will soon get cheaper and larger thanks to big announcements from Toshiba and Intel. Both companies revealed new “3D NAND” memory chips that are stacked in layers to pack in more data, unlike single-plane chips currently used. Toshiba said that it’s created the world’s first 48-layer NAND, yielding a 16GB chip with boosted speeds and reliability. The Japanese company invented flash memory in the first place and has the smallest NAND cells in the world at 15nm. Toshiba is now giving manufacturers engineering samples, but products using the new chips won’t arrive for another year or so.

“An analysis of the history of technology shows that technological change is exponential, contrary to the common-sense “intuitive linear” view. So we won’t experience 100 years of progress in the 21st century — it will be more like 20,000 years of progress (at today’s rate). The “returns,” such as chip speed and cost-effectiveness, also increase exponentially. There’s even exponential growth in the rate of exponential growth. Within a few decades, machine intelligence will surpass human intelligence, leading to The Singularity — technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.” — Ray Kurzweil.

‪#‎Handy‬ New Wireless Charger Can Simultaneously Power 30 Mobile Phones at Distance.

Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed an omnidirectional wireless charging technology that can charge multiple devices at once, at a distance and, crucially, at peak efficiency regardless of which way the devices are facing.

An effective wireless transmitting power of 30 watts means the device can, according to the researchers, power either 30 smartphones or five laptops simultaneously.

The results were published in last month’s issue of the journal IEEE Transactions on Power Electronics, and a spinoff company is now conducting pilot studies to apply this technology in cafes and offices.

Experimental apparatus scheme for a Brainet computing device. A Brainet of four interconnected brains is shown. The arrows represent the flow of information through the Brainet. Inputs were delivered (red) as simultaneous intracortical microstimulation (ICMS) patterns (via implanted electrodes) to the somatosensory cortex of each rat. Neural activity (black) was then recorded and analyzed in real time. Rats were required to synchronize their neural activity with the other Brainet participants to receive water.
