Today's briefing

What matters today

Today’s issue follows AI moving from output to workflow: an open neuroscience map is becoming a simulation playground, while study and coding tools put more emphasis on the work around generation. Google is expanding how people learn from their own sources, and smart-glasses detection is making bystander privacy more visible.

Developers run a fruit fly brain map in Minecraft and other simulations

Google Research and HHMI Janelia released MaleCNS v1.0 on September 3 alongside a Cell paper: a complete, proofread wiring diagram of an adult male fruit fly. Developers quickly began putting the open map into Minecraft, Doom, Beat Saber, and bitcoin-trading experiments. One Minecraft implementation said it ran all 166,700 neurons, with simulated neural activity driving a virtual fly’s movement; 404 Media reported that project drew millions of views within a day of its September 4 release.

The map covers more than 166,000 neurons and 125 million synaptic connections across the central brain, optic lobes, and ventral nerve cord. That is a major expansion from Google’s 2020 human-verified female hemibrain map, which covered half a brain with 25,000 neurons and 21 million connections. The new release extends the wiring diagram into the nerve cord, the structure analogous to a spinal cord.

Researchers built the reconstruction by using AI to stitch millions of two-dimensional electron-microscope images into three-dimensional neural structures, then had Janelia experts verify and annotate it. The map is browsable and downloadable through Neuroglancer, Google’s open-source visualization tool. A paired male and female connectome can support comparisons of structural differences associated with courtship, aggression, and regions that otherwise look similar.

The viral simulations are visually compelling, but they should not be confused with a digital living animal. MaleCNS v1.0 captures neural wiring and overall structure, not a fly’s complex biochemistry, sentience, or conscious perception. Its value is as a public anatomical reference—one that developers can animate in unexpected environments while researchers use it to study the nervous system.

Google adds voice chats and lecture recording to Gemini Notebook

Google is rolling out real-time voice conversations in Gemini Notebook’s Android and iOS apps in nearly 100 languages. The company says responses are grounded in sources stored in a user’s notebook, with users able to interrupt and ask for step-by-step guidance. A mobile audio recorder is planned for next week, storing lectures and thoughts as notebook sources. Google is also adding quizzes, flashcards, infographics, and roughly 60-second video overviews.

ZuckOff alerts people to nearby smart glasses over Bluetooth

Polish developer Pawel Szydlowski’s ZuckOff app detects Bluetooth broadcasts from Ray-Ban Meta, Oakley Meta, and Snap Spectacles, then estimates rough proximity. It can flag a compatible device but cannot identify its wearer, pinpoint it precisely, or determine whether it is recording.

BairesDev survey finds 42% say AI writes at least half their code

BairesDev’s Q3 2026 Dev Barometer found that 42% of respondents said AI writes at least half their code, up from 12% in its year-earlier survey. Developers reported saving 13 coding hours a week on average, but 67% said they spend more time reviewing AI-generated code and 52% more time debugging AI-introduced problems.
