- SkyWater PDK open-source chip initiative: a 130 nm CMOS process design kit has been released under permissive license, enabling open hardware fabrication and lowering barriers for custom ASIC projects (link: The Register article).  
- COVID-19 THz spectroscopy detection: researchers claim SARS-CoV-2 virions (100–140 nm) exhibit a resonant signature in the terahertz range, raising the prospect of rapid, label-free optical diagnostics (link: Med-Tech News coverage).  
- Debate on THz resonance practicality: participants note prior unfulfilled promises of THz detection for explosives and question whether the physics scales to real-world, low-cost devices.  
- Room-temperature superconductor update: arXiv preprint 2007.01531 reports stabilization of clathrate H cages in LaH₁₀, achieving superconductivity—but only at megabar pressures (~million atmospheres), tempering near-term applicability.  
- Log archival issues: gnusha logger downtime led to gaps in channel history; local logs were manually merged, highlighting the fragility of community knowledge preservation infrastructure.
