TypeScript 7.0 debuts as a native Go port delivering 8–12x faster full builds with shared-memory multithreading, plus parallelization controls (--checkers, --builders) and a rebuilt --watch. It runs side-by-side with TypeScript 6.0 via a compatibility package (@typescript/typescript6) and does not ship with a new API yet (7.1 will). Editor and language-server support are dramatically improved. Defaults shift (strict on by default; rootDir and types changes) and several older options are deprecated or become errors. Unicode code points are now preserved in template literal types.

The European Parliament approved an urgent procedure to fast-track legislation reviving the expired Chat Control 1.0 rules, setting up a July 9 vote on whether online platforms may again voluntarily scan private messages for CSAM. The temporary framework expired in April 2026; the Council seeks to reintroduce a similar measure, while negotiations on a permanent CSAM Regulation (Chat Control 2.0) continue. The two tracks risk confusion: the Parliament wants scanning limited to suspects with judicial authorization, the Council favors broader, voluntary detection. A majority vote could restore the temporary regime while talks proceed.

Australian environmental chemist Cassandra Rauert explains that measuring microplastics in the human body is hampered by lab contamination and lipid false positives that mimic polyethylene. She rebuilt a plastics-free lab to reduce contamination, noting many past blood-microplastics studies may be unreliable. Plastics pervade homes (dust, tire particles, dryer fibers, kitchenware) and food packaging, though the claim of eating a credit card’s worth weekly is debunked. Key questions remain: what exactly are we exposed to, how small can plastics get into the bloodstream, and what health effects occur? More research is needed.

Zed reviews Arnold's catastrophe-theory model of a creative personality with three parameters: technical proficiency (T), enthusiasm (E), and achievement (A). Projected onto the (T,E) plane, slow skill growth with low enthusiasm climbs a smooth ramp; with high enthusiasm and skill, one can become a genius; but enthusiasm growing without enough skill triggers a catastrophe where achievement drops, labeled “maniacs.” Jumps from genius to maniac follow different lines, and enough enthusiasm can align genius and maniac on the same T and E but with different A/history. The post critiques catastrophe theory's rigor while endorsing the image as a handy caricature of intellectual development, echoed in reader comments.

Biohacker Bryan Johnson, founder of Braintree, spends over $2 million yearly chasing immortality and now says he has autoimmune gastritis, an incurable condition that causes his stomach to eat itself, with irreversible damage and elevated cancer risk. He has used blood from his teenage son and other young donors for aging experiments, and maintains a strict regimen—54 pills daily, two dozen meds, heavy monitoring, and prescribed routines. Netflix covers his quest in Don't Die: The Man Who Wants to Live Forever. He pursues aging neutralization through Project Blueprint, though medicine offers no cure.

SWE-1.7 is Cognition’s most capable model yet, achieving frontier-level intelligence at a fraction of the cost. Trained from the Kimi K2.7 base, it uses a revamped RL pipeline—improved infrastructure, higher-quality data, stability, and long-horizon techniques—to push beyond prior post-training limits. Optimized for long, asynchronous tasks, it’s available in Devin (Web/Desktop/CLI) via Cerebras at 1000 TPS. Key innovations: entropy-preserving training (top-p sampling with rollout replay), multi-cluster training across three continents with fault tolerance, data-quality pipelines, and self-compaction with an alternating length penalty. Results show greater alignment, concise reasoning, and deeper codebase exploration; evaluated on FrontierCode, SWE-Bench, Terminal-Bench.

Kastor is a declarative language and toolchain for AI agents. It defines agents, tools, and prompts in HCL (.agent, .tool, .prompt) and a Go-based workflow with two paths: kastor build (generates runnable projects for target frameworks) and kastor plan/apply (reconciles long‑lived agents on hosted platforms with state, diffs, and drift detection). It’s an early PoC; current work parses specs, validates references, and generates LangGraph projects (e.g., weather agent). Planned: local state drift and AWS/Azure deployment. Install via Homebrew or install script; SPEC.md is the design source.

Chatto is now Open Source and self-hostable. Quick start via Homebrew or binaries for Linux (x86_64/ARM64), macOS, and Windows. It prioritizes privacy: data at rest encrypted with per-user keys, no federated data or third‑party tracking; each server runs a single community and clients can connect to multiple servers. It includes built‑in voice/video with end‑to‑end encrypted calls. Chatto Cloud will enter public beta in Europe with auto‑scaling, nightly backups, and no lock‑in. Version 0.4 with 1.0 expected in 6–12 months; feedback via the community.

The Atlantic examines a looming 'postliterate' era in which reading declines despite technology abundance. Tracing history from Alexandria to Gutenberg to TV and the internet, it shows Americans read less for pleasure, news, and deep analysis, while exposure to short-form content dulls attention and harms comprehension. Education pushes for excerpts; students struggle with longer texts; cognitive research links reduced reading to weaker reasoning. The piece argues the rise of AI and social media heightens risk to thought, while a committed minority keeps reading as a civic and cultural anchor. The future of literacy hangs in the balance.

Cloudflare's Meerkat is an experimental global consensus service to manage control-plane state across 330+ data centers. It uses QuePaxa, a non-leader, majority-quorum consensus that allows writes from any replica and avoids leader failures that block writes in Raft. Meerkat maintains a common log of events; decided slots ensure linearizable reads/writes for applications like a KV store. QuePaxa offers higher throughput in unreliable networks and hardware faults, addressing wide-area latency issues. It's not production-ready, but proofs-of-concept with up to 50 replicas show resilience; Cloudflare will publish more on architecture, verification, and deployment.

Robostral Navigate is an 8B in-house model enabling autonomous navigation with a single RGB camera in complex environments. It achieves 79.4% seen and 76.6% unseen R2R-CE, outperforming depth- or multi-sensor systems while using no depth data. Trained entirely in simulation with ~400,000 trajectories across 6,000 scenes, it uses prefix-caching for token-efficient supervised training and online RL (CISPO) to improve post-training. Navigation relies on pointing to predict the next image coordinate, with a local-displacement fallback. Generalizes across wheeled, legged, and flying robots; a step toward unified embodied AI with wide applications.

Japan's Hayabusa2 completed a close flyby of asteroid Torifune as part of its Extended Mission, delivering images and confirming mission success. The probe, which carried samples from Ryugu to Earth six years ago, approached within about 800 meters at 5 km/s. Results and photos will be shared at a news conference; the effort aims to refine precise high-speed asteroid flyby navigation and support planetary defense, with a final target asteroid expected in 2031.

The FDA has rejected a petition calling for legally binding PFAS limits in food. The Tucson Environmental Justice Task Force sought thresholds for up to 30 PFAS across produce, seafood, eggs, milk and bread in 2023; it later narrowed to advisory levels for PFOA and PFOS in seafood and milk in 2025. The agency says there’s insufficient evidence for mandatory limits and will instead propose non-binding “action levels.” Independent testing has found PFAS in seafood, milk, meat and produce, sometimes at high levels, underscoring ongoing exposure concerns.

Devon’s Exmouth Leisure Centre is heating its swimming pool with a washing-machine-sized data centre surrounded by oil to about 30C for roughly 60% of the time, saving thousands in energy costs. The “digital boiler” is provided free by Deep Green, which will refund the centre’s electricity costs; seven other England pools have signed up. The system reuses waste heat from data centres via a heat exchanger to warm pool water, addressing soaring energy bills that have shut many pools.
