Study found a significant “wealth gap” among older people in England, with poorer people showing signs of reduced physical function up to 15 years earlier than richer people of the same age. This was still significant even when chronic illness, weight and smoking and alcohol were taken into account.

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.
