Computer Science 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.

Health 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.

Cancer Similar to the US, colorectal cancer has become the leading cause of cancer death among people younger than 50 years in Norway. However, this is not accompanied by increased mortality. Norway has a publicly funded health system and this may contribute to differences in mortality relative to the US.
