Zhang/Penn State In Penn State’s Materials Research Institute, an electrical engineer and a biomaterials engineer have joined their expertise to develop a flexible, biodegradable optical fiber to deliver light into the body for medical applications. The ability to deliver light into the

These stem cells have the features of the very first cells

This artist’s representation shows an electron beam (in purple) being used to create a 2D superlattice made up of quantum dots having extraordinary atomic-scale precision and placement.

According to the researchers, creativity is our ability to think in new and original ways to solve problems. Credit: © Photographee.eu / Fotolia Developing an original and creative idea requires the simultaneous activation of two completely different networks in the brain: the associative — “spontaneous” — network alongside the more normative — “conservative” — network;

This is a rendering of what the Osaka University research team’s SR device entails. Credit: Megumi Akai-Kasaya In conventional electronics, a great deal of effort is devoted to eliminating stochastic resonance (SR) — the annoying hiss that generally hinders the detection of weak signals and degrades overall device performance. But, what if there were a

The communication range of many low-power devices is limited to several feet. The UW’s long-range backscatter system’s sensor (shown in the foreground) was able to communicate with a receiver (held in the distant background) throughout a one-acre farm, a 4,800-square-foot house and an office area covering 41 rooms.

Silicon in lithium-ion batteries shows great promise. Credit: Timo Ikonen Silicon — the second most abundant element in the earth’s crust — shows great promise in Li-ion batteries, according to new research from the University of Eastern Finland. By replacing graphite anodes with silicon, it is possible to quadruple anode capacity. In a climate-neutral society,

Schematic (animated) of torsional optomechanical resonator for sensing and frequency mixing.

As electronic devices get smaller, their ability to provide precise, chip-based sensing of dynamic physical properties such as motion become challenging

This is an aerial view of the Virgo site showing the Mode-Cleaner building, the Central building, the three kilometer-long west arm and the beginning of the north arm. The other buildings include offices, workshops, computer rooms and the control room of the interferometer. Credit: The Virgo collaboration/CCO 1.0 In August, detectors on two continents recorded

Silicon carbide power devices, like the one shown here, are more efficient than their silicon counterparts. Credit: NC State University Researchers from North Carolina State University are rolling out a new manufacturing process and chip design for silicon carbide (SiC) power devices, which can be used to more efficiently regulate power in technologies that use
