Complete map of a male fruit fly's nervous system published

Google Research, HHMI Janelia, and collaborators published a proofread map of the male fruit fly's brain and central nervous system yesterday, covering more than 166,000 neurons and 125 million connections between them. AI reconstruction tools turned stacks of electron-microscope slices into 3D neuron shapes, and human experts then verified and annotated the result. With a complete male nervous system in hand, researchers can follow a signal from sense organ to muscle and set it beside the existing female maps to study differences in behavior and learning. The map is openly available, and the same reconstruction pipeline is what larger animal brains will need.

WeatherNext 3 forecasts the globe hourly at 5-kilometer resolution

Google's WeatherNext 3 went live yesterday, taking in live satellite observations and producing global forecasts hour by hour at resolutions down to 5 kilometers. WeatherNext 2 worked on a 25-kilometer grid in six-hour steps, so a farm, a fire crew, or a wind-farm operator now gets a local picture that refreshes far more often. Google says its precipitation evaluations improved by up to 60% against IMERG, and that longer-range rain forecasts in its consumer products are up to 50% more accurate. The model also predicts wind at turbine height, cloud cover, and solar radiation, the measurements used to estimate how much power a wind or solar site will generate.

Gemini works inside Gmail, Docs, and Keep on voice command

Yesterday, Google put Gemini to work inside three of its own apps, in English on mobile worldwide. Ask Gmail Live what a sender promised and it searches the inbox, answers, and shows which emails it used; Docs Live assembles a document from a spoken brief; Keep Live transcribes a note and adds context to it. The assistant now runs where the data already sits, so nothing has to be copied into a separate chat window first.

Microsoft's MAI-Transcribe-2 handles 60 languages at 10 cents an hour

Ten cents buys an hour of transcription from MAI-Transcribe-2, which Microsoft made available yesterday and priced that way through the end of 2026. The model separates speakers (that is, labels who said what), stamps each word with its own timestamp, and can be set to produce verbatim text or a cleaned-up version, with keyword biasing and automatic language detection included. It also handles code switching, meaning a speaker who changes languages mid-conversation, and Microsoft reports a 5.2% average word-error rate across the 60 languages in the FLEURS benchmark. One model can now cover captioning, meeting notes, clinical documentation, and multilingual transcription that developers used to assemble from separate services.

NVIDIA's PAIR spreads AI jobs across computers on one network

NVIDIA published PAIR, short for Personal AI Router, yesterday as an open-source beta that hands separate Ollama and LM Studio inference requests to whatever compatible computers sit on the same local network. In NVIDIA's own five-subagent demonstration, a three-machine cluster finished in 8 minutes 48 seconds against 18 minutes on a single RTX Spark laptop, with the result tied to that specific configuration. Anyone running agents at home or in a small office can put idle laptops and desktops to work without rewriting the agent software, and prompts stay on the local network. PAIR also steers requests away from machines that are already busy.

Fly-inspired algorithm learns new smells without forgetting old ones

Researchers at the Okinawa Institute of Science and Technology published Spi-Fly yesterday, an odor-classification algorithm modeled on the sparse wiring a fly's brain uses to tell smells apart. In simulations on recorded gas-sensor data, the authors say it reached its best accuracy after three exposures to each odor, held on to the odors it already knew while learning new ones, and lost less accuracy than backpropagation, the standard training method, when memory was constrained. A sensor that can pick up a new smell without being retrained from scratch is cheaper to run and easier to update in place. The team built it with neuromorphic chips, meaning processors designed to imitate neurons, as the eventual target.

Uber and Wayve start London robotaxi rides with safety operators

Uber and Wayve opened London's first public robotaxi service today, matching riders who request UberX, Uber Comfort, or Uber Electric with an autonomous Ford Mustang Mach-E at no extra charge. A safety operator rides along on every trip in this phase and can take the wheel. Riders can accept the autonomous car, switch to a conventional ride, or opt in to raise their chances of getting one. The launch carries Wayve's map-light approach, which leans on a driving model instead of detailed prebuilt maps, out of road testing and into ordinary ride-hailing in a dense and difficult city.

AGS-PlantSeg picks its own scale for 3D plant segmentation

Separating a 3D scan of a plant into individual leaves and stems usually means tuning a model for each species or growth habit. Researchers presented AGS-PlantSeg today, which chooses three spatial granularities for each plant it examines instead of applying one fixed scale to every specimen. Across its cross-species tests the method reports 88.9% average mean intersection-over-union (that is, how closely the predicted shapes overlap the true ones), compared with 86.4% for the best fixed-granularity baseline. Training stays cheap, since the encoder is frozen and only a two-layer prediction head is fitted.

ChatGPT, Claude, and Grok all go down the same day

ChatGPT and Codex, Anthropic's Claude products and API, and xAI's Grok all suffered significant disruptions within the same stretch yesterday then recovered. xAI blamed its Memphis data center, Anthropic pointed to an infrastructure issue, and OpenAI said it had applied a mitigation. Logins, file uploads, research sessions, coding tools, and agent jobs running through those APIs stopped at once. Anyone whose work routes through hosted models got a practical reason to write down a manual fallback procedure.

Hyperscale Data ends Michigan bitcoin mining for an AI tenant

Hyperscale Data stopped Bitcoin mining at its Dowagiac, Michigan facility on Sept. 1 and is pointing the site's power and infrastructure at an unnamed cloud customer instead. That tenant is contracted for 20MW of AI infrastructure in the fourth quarter of 2026, with a possible expansion to 52MW. A site whose grid connection and buildings already exist can host compute sooner than a campus built from bare ground.
