 Using simulated silicon 'neurons', scientists found that energy constraints on a system, coupled with the intrinsic property neurons have to move to the lowest-energy configuration, leads to a dynamic, at-a-distance communication protocol that is both more robust and more energy-efficient than traditional computer processors.
 Researchers have implemented an advanced quantum algorithm for measuring physical quantities using simple optical tools. This study takes us a step closer to affordable linear optics-based sensors with high performance characteristics. Such tools are sought after in diverse research fields, from astronomy to biology.
 When you speak softly in one of the galleries of St Paul's cathedral, the sound runs so easily around the dome that visitors anywhere on its circumference can hear it. This striking phenomenon has been termed the 'whispering gallery' effect, and variants of it appear in many scenarios where a wave can travel nearly perfectly around a structure.
 Encoding information in twisting beams of light could break bandwidth bottleneck in optical communications.
 Distinct from traditional spin valves with a sandwich structure consisting of two ferromagnetic metals decoupled by the insertion of a non-magnetic spacer, recently, a research team has demonstrated two-state and three-state spin-valve effects using Fe3GeTe2 vdW homo-junctions without any spacer layer. Realization of multi spin states using the vdW interfaces could be important for non-volatile spintronic applications.
 Scientists have shown how wrinkles can be increased or reduced by altering the curvature at the edge of a material.
 Physical properties of the effect and simplicity of its reproduction make it promising for application in microelectronics, photonics, and the on a chip systems, where a single microcircuit functions as an entire device.
Bismuth antimonide (BiSb) is an important material in nanoelectronics as a topological insulator and as a thermoelectric material. However, some of its thermal properties are still mostly unknown at the nanoscale. This is an issue because in order for BiSb to exhibit its thermoelectric properties it has to be an alloy. But at the nanoscale, it is difficult to mix Bi and Sb. New findings provide the phase diagram of bismuth antimonide at nanoscale sizes for different types of morphologies like sphere, rod, wire, and film, thereby filling the knowledge gap about the thermal properties of BiSb at the nanoscale.
 Sometimes, breaking rules is not a bad thing. Especially when the rules are apparent laws of nature that apply in bulk material, but other forces appear in the nanoscale.
 A response to light usually seen only in inorganic compounds has been realized in organic liquid crystals, opening the way to highly responsive photodetectors.
