- Fifty countries and the EU issue a joint statement on September 23, delivered by Danish Foreign Minister Lars Løkke Rasmussen ahead of a UN Security Council meeting, calling on Russia to accept the full, immediate and unconditional ceasefire Ukraine says it agreed to as early as March 2025; the United States does not join the statement. ↗
Business & markets
- The 10-year Treasury yield jumps to 5.11% on September 24, its highest level since 2007, and the 30-year touches a post-2004 peak of 5.438%, after S&P Global flash PMI data show new orders and input/output prices at multi-year highs and fuel bets on another Fed rate hike this year. ↗
- The Dow Jones Industrial Average falls 360 points (0.69%) on September 23 to close at 51,503, with US stock futures sliding further Thursday morning as inflation fears and the bond selloff outweigh hopes for Middle East diplomacy. ↗
Bitcoin & crypto
- Bitcoin opens at $84,370.41 on September 24, down 2.1% from Wednesday, then falls further to $83,462.29 by 7:33 a.m. ET as CME's FedWatch tool puts the odds of an October Fed rate hike at 75.3%. ↗
- The CFTC opens an investigation into Polymarket after a Wall Street Journal report that CEO Shayne Coplan told staff to "keep growing and pay a fine" rather than fix compliance gaps exposed by a February attempt to steal $10 million from its US platform, an episode that already cost the company its chief compliance officer and its US CEO. ↗
Technology
- Cisco Talos discloses CLOSEDQUORUM on September 22, a Windows implant it calls the first documented malware to hand tactical attack decisions to a panel of four commercial AI models — DeepSeek, Qwen, Mistral and Google Gemini — that vote on each move, while releasing an open-source detection toolkit called CAIRN and stating it has not confirmed the malware deployed against real victims. ↗
- OpenAI launches GPT-6 Sol and GPT-6 Luna on September 22, roughly 90 minutes after Anthropic's own Claude Opus 5.5 price cut, pricing Sol at $2/$10 per million input/output tokens (down from $4/$20) and Luna at $0.10/$0.50 (down from $0.20/$1.20). ↗

- A study led by Pablo Santos-Sanz of Spain's IAA-CSIC, using a James Webb Space Telescope stellar occultation from October 2022, finds the centaur Chariklo's ring system has visibly changed in just a few years — its inner ring growing denser and its outer ring fainter. ↗
Health & medicine
- A Peking University-led study tracking more than 95,000 adults' wrist-monitor sleep data over nine years finds each 47.6-minute increase in REM sleep is tied to a lower risk of 83 diseases, including heart failure, dementia and Parkinson's, while more deep sleep is linked to lower risk of seven conditions including type 2 diabetes. ↗
