- Scientists discover two brains in one body
Stanford Medicine study reveals the brain consists of two ancient nervous systems. One controls basic functions, the other enables human-specific abilities.
- Researchers find link between language learning and maintaining cognitive functions
Language learning engages multiple mental processes. Studies suggest it may slow brain aging.
- GPT Models Transform, Don't Reduce, Gender Discrimination
Study shows GPT models shift, not reduce, gender discrimination across generations. Men's representations improve while women's decline.
- Celeris builds fastest LLMs with diffusion
Celeris is building the fastest LLMs by starting with diffusion models, which enable parallel generation and faster processing.
- Spindle oscillations suppress epileptic discharges
Sleep spindles suppress epileptic discharges, while epileptic activity increases spindle probability. Study conducted on 55 epilepsy patients.
- Vantora builds startups exclusively for corporate clients
Vantora, formerly UP.Labs, raised $100M and now builds startups exclusively for corporate clients like Porsche and Alaska Airlines.
- Built node with 4 RTX6000 Blackwell Pro Max-Q GPUs
A 4x RTX6000 Blackwell Pro Max-Q setup reached 102 TPS, 2.1x higher than v4-flash.
- AI speeds up decision-making in under 40 milliseconds
Researcher developed a fast, schema-based decision model with reinforcement learning. Published in arXiv and available on Hugging Face.
- Registration for TechCrunch Disrupt 2026 ends September 25
Ticket prices for TechCrunch Disrupt 2026 will increase after September 25. Register before the deadline to save up to $200.
- Scientists and citizens will march for longevity in Madrid
A public march for longevity in Madrid includes reading sections of the Madrid Longevity Declaration. Organizers demand more funding for aging research.
- Database persists after reload
DuckDB-Wasm can now persist databases in the browser's OPFS. This enables data persistence across sessions.
- Sensor detects nitrates in soil
Study shows spinal Tac1-lineage neurons split into subtypes involved in pain processing. Adult neurons show functional diversity, while embryonic ones are uniform.
- Eli Lilly shows brenipatide effectiveness in treating psychiatric disorders
Lilly presented early positive data on brenipatide, a dual GIP/GLP-1 agonist, showing potential for weekly dosing in substance use and psychiatric disorders.
- Method shows lack of power in gene analysis
Even with 600 donors, single-cell methods fail to reliably detect small genetic effects. Over half of differentially expressed genes are lost when analyzing microglia.
- Sensor detects nitrates in soil
One ring around Chariklo has become denser, and another has almost vanished. The reason remains unknown.
- Sensor detects nitrates in soil
The update includes improvements in GitHub Copilot integration and agent workflow enhancements.
- Drosophila gets updated transposable element libraries
Dfam 4.0 consolidates transposable element libraries for Drosophila melanogaster, integrating data from multiple sources and resolving redundancy.
- Model predicts probabilities in seconds
Developer published Laya, a model based on reinforcement learning and schemas. The model was developed in 2025 and published in arXiv.
- Seniors in short supply: no more junior engineers
AI has taken over entry-level work, leaving a shortage of senior engineers. Companies will need them to drive agent fleets, but few are being trained now.
- German keys helped break ADFGVX encryption
AI decrypted the ADFGVX cipher used by Germans in World War I. The cipher was used to encode radio messages.
