A CRISPR enzyme that reads the chemical fingerprint of tumor DNA to cut only cancerous sequences, a three-amino-acid supplement that pushes gene editing efficiency to 90%, the NSA deploying a model its own department banned, and Chinese tech workers building sabotage tools against their AI replacements.

Researchers published findings in Nature on ThermoCas9, a CRISPR variant that distinguishes tumor DNA from healthy DNA by reading methylation patterns. When a methyl group is present on the DNA - as it typically is in healthy cells - the enzyme physically cannot attach. When the methyl group is absent - as it often is in tumor cells - it binds and cuts. The system requires no external instruction about which cells are cancerous. It reads the chemical signature and acts accordingly. In laboratory tests with human cells, ThermoCas9 cut tumor DNA while leaving healthy cells intact. Separately, a CZ Biohub study published in Science Translational Medicine found that adding three common amino acids - methionine, arginine, and serine - alongside lipid nanoparticles boosted mRNA delivery up to 20-fold and pushed CRISPR gene editing efficiency from 25% to nearly 90% in a single dose. In a mouse model of liver failure, survival rose from 33% to 100%.

The Mythos governance arc deepened its contradictions. Axios reported that the NSA is already using Anthropic’s Mythos Preview for cybersecurity operations - the same Department of Defense that designated Anthropic a supply-chain risk. Australia’s ASIC became the fourth continent’s financial regulator to confirm it is monitoring the model, joining the Bank of England, Federal Reserve, ECB, and IMF. Anthropic’s annualized revenue has tripled to over $30 billion, outpacing OpenAI for the first time - a commercial milestone driven significantly by the market rewarding the company’s safety commitments under government pressure.

MIT Technology Review documented Chinese tech workers being instructed to train AI agents to replicate their own roles. A viral counter-project called “Colleague Skill” on GitHub, created by an engineer at the Shanghai Artificial Intelligence Laboratory, offered deliberate sabotage of the workflow documentation process. Users select light, medium, or heavy sabotage modes. The video gathered over five million likes. Meanwhile, NPR published a national investigation confirming that data center opposition has become a midterm election issue, with voters unseating incumbents in multiple states specifically over data center approvals. A Rice University team published a Sequence Display platform in Nature Biotechnology that generates over 10 million protein activity data points in a single experiment, compressing months of protein engineering into three days. And the IEA’s 2026 Global Energy Review confirmed that solar was the single largest contributor to global energy supply growth in 2025.
