Deep, chewy, rich, digestible. A cracking good job by #ScienceJournalist Zack Savitsky.

''But the implications go beyond just building better superconductors. A theory that explains strange metals may force a fundamental rethinking of how electricity works in all materials. It might subsume the standard theory the way general relativity, with its curved spacetime, subsumed Isaac Newton’s theory of gravity—and prove just as unsettling. Strange metals are forcing physicists to ask whether the very idea of an electron, or any particle for that matter, is an oversimplification of what’s really going on. “The violation of the standard theory of solids in these strange metals is so dramatic—it’s in your face,” says Qimiao Si, a physicist at Rice University who collaborates with Paschen. “There’s no question there’s new physics.”''

map - Complete USMTArray and community magnetotelluric surveys in North America as of June 27, 2024. Magnetotelluric sites are distributed across the continental US and are represented with hundreds of inverted triangles including orange (EarthScope), blue (MTArray), red (NRCan Lithoprobe), black (USGS) and clear (other surveys). Magetic observatories are indicated with stars, three red (NRCan) and six black (USGS). Ten USGS variometers are indicated with pink 4-point stars.graphic / schematic - spaceweather possible impactsphoto - Northern Lights over high voltage powerlinesscreenshot - NOAA space weather prediction center geoelectric field map model

An Ultra-Stable Protein Nanowire Made by Bacteria microbiologycommunity.nature.c

Structure of #Geobacter cytochrome OmcZ identifies mechanism of nanowire assembly and conductivity nature.com/articles/s41564-022

#Bacteria deep in the #soil need #nanowires made up of #cytochrome OmcZ to export electrons to extracellular acceptors in order to survive without oxygen. New research explains how bacteria make nanowires on demand and why only OmcZ nanowires show extremely high electron #conductivity.
