OpenAI is reportedly negotiating a massive private funding round of up to $30 billion that would value the company at roughly $1.25 trillion, potentially setting a record as the most valuable private firm. The deal, led by Coatue and UAE investors, could also include additional computing capacity, while the company delays an IPO it filed paperwork for in June.
Microsoft’s new AI diagnostic system, MAI‑DxO, outperformed generalist physicians in a simulation of complex cases, achieving an 83% accuracy rate versus 36% for doctors. The system, which coordinates multiple AI agents and leverages top‑tier models like OpenAI’s GPT‑5.5, is touted as a step toward “medical superintelligence” and could reshape healthcare diagnostics.
Two critical vulnerabilities discovered in PHP—affecting every version released over the past two decades—have forced high‑profile sites like Wikipedia, WordPress, the Internet Archive and even government services offline, with many older sites facing permanent shutdown. Security firm Wiz calls the flaws among the most severe ever seen, and they were identified with the help of advanced AI tools.
NVIDIA unveiled Kumo Relational, a pre‑trained foundation model that predicts outcomes directly from enterprise relational databases without any task‑specific training or feature engineering. In tests on 41 tasks across 15 databases, it outperforms supervised deep‑learning models and expert‑crafted XGBoost pipelines, even beating AutoGluon ensembles on the SAP SALT benchmark, and scales to databases with over 500 billion rows.
The PHP Foundation has issued emergency patches for two critical vulnerabilities (CVE-2026-109618 and CVE-2026-109619) affecting all PHP installations back to version 5, potentially allowing unauthenticated remote code execution and wormable attacks. Experts warn that attackers could begin exploiting these flaws within minutes, prompting governments and major sites to go offline and urging immediate updates, especially as AI tools have accelerated discovery and exploitation.
Microsoft claims its new AI diagnostic tool outperforms human physicians, achieving up to four times greater accuracy in tests using medical case reports and emergency department data, with results published in Science. The company says the system could transform healthcare by providing more reliable diagnoses than doctors.
Permafrost, covering about 15% of the Northern Hemisphere, stores millennia‑old organic carbon that releases CO₂ and methane as it thaws, creating a potent climate feedback that many UN models currently overlook. Intensifying boreal wildfires further accelerate thaw, potentially adding 80 billion tonnes of carbon to the atmosphere by 2100, prompting calls to reassess fire‑management policies and improve climate modeling.
