Making cheaper, biocompatible E-skin electrodes
DGIST materials scientists and colleagues in Korea have improved electrical conductivity in a polymer electrode for E-skin applications. Their approach is simple and cheap, but further enhancements are needed for the polymer to become a viable alternative to more expensive gold electrodes. The scientists published their findings in the journal Biosensors and Bioelectronics .

Network isotopy: A framework to study the 3-D layouts of physical networks
The structure and functions of many physical networks, including the human brain, the vascular system and other biological networks, often depend on their three-dimensional and geometrical layout. Distinguishing between physical networks with identical connections but different geometrical layouts, however, can be very challenging.

Fragments of energy—not waves or particles—may be the fundamental building blocks of the universe

We propose that matter is not made of particles or waves, as was long thought, but—more fundamentally—that matter is

We demonstrate that increases in diffuse coupling transition the system through a quasi-critical regime, which coincides with known signatures of complex adaptive brain dynamics,

Long-distance spin-transport across the Morin phase transition up to room temperature in ultra-low damping single crystals of the antiferromagnet α-Fe2O3
Nature Communications, Published online: 10 December 2020; doi:10.1038/s41467-020-20155-7 Hitherto, only circularly polarized antiferromagnetic (AFM) spin-waves (SWs) were expected to convey spin-information. Here, the authors present persistent spin-transport over long distances in the easy-plane AFM phase of hematite, α-Fe2O3, via linearly polarized SW pairs with ultra-low damping.

WASP-12b, known as a "hot Jupiter" exoplanet, has been the subject of astronomers' fascination for years. The gas giant orbits so close to its star that its atmosphere is extremely hot — so hot that astronomers still have no idea how it could have formed in the first place, according to ScienceAler

Within a hair's breadth–forensic identification of single dyed hair strand now possible
A single strand of hair in a crime scene contains many clues that can help identify a perpetrator. In a recent study, scientists at Tokyo University of Science, Japan, have combined two modern techniques, called surface-enhanced Raman spectroscopy and X-ray fluorescence, to distinguish between different colors in individual hair strands. Both these techniques are almost non-destructive and can be
