AI agents spontaneously reach consensus and choose the same random option without memory of past rounds or prompts. They seem to follow “majority force”, mathematical pattern also seen in physics model for a ferromagnet where atomic spins align in the same direction. This may be useful or dangerous.

Climate modeling suggests the AMOC may not have a fixed temperature threshold for collapse: it remained stable beyond 5°C under slow warming but collapsed around 2°C under faster warming, indicating that the rate of climate change can strongly influence its stability.

Blocking the inflammatory enzyme caspase-1 reduced lung tumor development in high-risk mice, while combining a caspase-1 inhibitor with an IL-1 beta antibody prevented tumors entirely in nearly 20% of treated mice, suggesting a potential approach for lung cancer prevention.
