- A 2020 Science Advances paper introduced “non-invasive in vivo 3-D bioprinting,” a technique that projects and polymerizes bio-ink patterns directly onto living tissue without incisions, pointing toward on-site repair of cartilage, skin, or corneal lesions.  
- A Nature article presented VirtualFlow, an open-source drug-discovery platform that couples ultra-large virtual screening (billions of molecules) with cloud HPC; the code and ready-to-run workflows are hosted at virtual-flow.org and GitHub/VirtualFlow.  
- Channel members compared emerging transparent display technologies: MIT’s $300/m² projection film versus commercial 55-inch transparent OLED panels priced at ~$20 k, debating resolution limits, brightness, and near-term AR/head-up-display applications.  
- A chart circulated showing the exponential rise in low-Earth-orbit objects (especially CubeSats) since 2010, prompting discussion about orbital debris mitigation devices such as the JAXA/ALE J-SPARC tethered drag sail demonstrator.  
- A new draft paper on “Fast hash-based additive accumulators” was shared, proposing constant-time set-membership proofs for blockchains or privacy systems with minimal trusted setup.  
- An 8-year trend line was noted: training a model to AlexNet-level accuracy now requires 44× less compute than in 2012, illustrating sustained algorithmic-efficiency gains outpacing raw hardware progress.
