Perplexity released a specialized classification model that returns probability distributions over fixed answer options instead of generating free-form text, shipping in a full Qwen-27B version and a distilled Qwen-4B "Flash" variant. Trained in three stages — generalist fine-tuning, LoRA domain specialization, then vision — it hit 91.6% on query classification and 93.98% agreement with frontier LLM judges across 2.3 million production questions. The kicker is cost: $26.47 versus $68.10 for competing approaches, with internal use already cutting security-rule false positives by 52%.

Haddy Alchaer ran 600 experiments against LeWM, a JEPA world model, on the Push-T robotics benchmark — and never retrained the model once. The finding: the predictor is already as good as perfect physics for planning purposes, so the real bottleneck is planning strategy, not prediction quality. Hierarchical subgoals took 75-step task success from 22% to 80%, a memory graph with jump costs hit 85%, and simply cleaning the robot out of the goal image improved success fourfold.

Six pallets of Nvidia hardware worth $11.4 million disappeared on August 29 en route from Oakland to Fort Worth, picked up by a truck wearing a food-transport company's logo that investigators lost track of in San Bernardino County. No arrests, and authorities still haven't named the shipper, carrier, or driver. It's part of a pattern — roughly $111 million in stolen data center freight, plus $7.5 million in Nvidia product lifted from Fremont and Union City burglaries last year.

Autonomous Technologies Group, a Brooklyn-based YC Fall 2025 lab founded in 2025, is hiring Members of Technical Staff to build autonomous systems for "complex decision-making in uncertain environments." The pitch blends AI research, machine learning, and algorithmic trading into agents that manage investment portfolios with minimal human intervention. They're explicitly recruiting across disciplines rather than pure quant backgrounds.

At 20:54 UTC today the FAA halted departures nationwide after a communication failure hit every Air Route Traffic Control Center, with Transportation Secretary Sean Duffy citing "extraordinary circumstances." FlightAware logged at least 8,000 delays and 400 cancellations, with major impacts in Boston, Atlanta, Miami, Pittsburgh, New York, Los Angeles, and Baltimore. It's only the third nationwide ground stop in US history, after September 11 and the 2023 NOTAM outage.

Scott JG wanted his Coway Airmega IconS in an Apple Home "Good Night" scene without depending on Coway's flaky cloud, so he built a Raspberry Pi access point, piped the device's traffic through mitmproxy, and found the purifier fetching its root certificates over plain HTTP. He then decoded the Bluetooth provisioning protocol from Android's debug logs, finding an AES-encrypted payload containing redirectable certificate-server URLs. The result is a Home Assistant custom integration giving full local MQTT control with the cloud cut entirely out of the loop.

In November 1960, Heinz von Foerster, Patricia Mora, and Lawrence Amiot published a Science paper fitting 2,000 years of population data to a curve that goes vertical at 2026.87, plus or minus 5.5 years. Von Foerster picked today specifically because a Friday the 13th fell conveniently inside the window — and because it was his own birthday. The equation tracked reality surprisingly well until roughly 1993, when growth rates finally bent away from the singularity.

M-VAVE shipped a browser-based editor for the FM-1, a polyphonic hardware synth with 8 tracks, 6 synthesis engines, and 16-step sequencing covering FM, 303-style analog modeling, drums, and samples. It talks to the hardware over USB-MIDI using Web MIDI in Chrome or Edge, and handles projects, effects, and firmware updates from the page. The notable part for HN: it's GPLv3 with an SDK linking exception, source and dev kits public, and the HTML runs offline once downloaded.

Nature reports researchers identified a protein that pushes cells along the ageing pathway while sidestepping the inflammatory cascade that normally accompanies senescence. Decoupling the two matters because anti-ageing interventions have historically had to trade one problem for the other. It opens a cleaner target for therapies that slow ageing without the collateral immune damage.

A live aviation radio stream out of Orcas Island in the San Juans jumped onto the front page as people hunted for real-time signal on the ground stop. The site runs multiple channels including ATIS and AWOS, with an automatically compiled traffic board transcribing radio calls. It carries the appropriate warning that the auto-compiled board can be wrong or incomplete and is not for navigation.
