8 El Niño stronger than any point in the last 1,000 years, study finds¶

A University of Michigan study analyzing 1,000 years of coral records from the Galápagos Islands found that current El Niño conditions are stronger than any episode in the past millennium. Temperature variability since 1984 is 36.5% higher than pre-industrial levels, with modern El Niño events showing patterns fundamentally different from historical precedents.

7.5 'Stunning' percolation proof resolves decades-old phase transition puzzle¶

Five mathematicians proved a decades-old conjecture in percolation theory about phase transitions in networks, demonstrating how networks abruptly shift behavior past a critical point. The breakthrough applies to broad network classes and resolves fundamental questions about fluid flow rates in percolation systems.

Proof developed by researchers at ETH Zurich in December 2025
Addresses phase transition behavior in network percolation
Applies to broad class of networks
Percolation theory models fluid seepage, virus spread, gas filtration, and wildfire propagation

7.5 Anthropic shuts down hijacked accounts mining AI tokens with stolen credentials¶

Anthropic shut down a credential-theft campaign that used commodity infostealer malware to hijack user accounts and exploit their paid Claude API token usage. The attackers stole authenticated sessions and cookies to bypass multi-factor authentication, but the malware itself is unrelated to Claude.

Infostealer malware targeted Claude users' credentials and session cookies
Attackers exploited victims' paid token quotas without authorization
Anthropic logged affected users out and removed saved payment methods
Malware is commodity tool, not Claude-specific threat
