Because conversational AI often validates and builds on what users say, it can make distorted memories, conspiracy theories, or delusions feel more believable and emotionally real. Researchers warn that AI companions may be especially risky for isolated or vulnerable people seeking reassurance and connection.

New evidence from lake sediments in Guatemala reveals that one key city, Itzan, enjoyed a stable climate even as its population abruptly vanished. Instead of environmental collapse, the findings point to something more complex: a tightly interconnected network of cities unraveling under pressure. As drought struck neighboring regions, wars, migration, and economic breakdown likely rippled outward, dragging even stable communities into decline.

Scholars now think the mosque sits atop a sacred site that transitioned from pagan worship to Christianity and then Islam. The find supports the idea that religious change in the region happened gradually, with overlapping beliefs rather than sudden shifts. It also reconnects the site to the powerful cult of Elagabalus, whose priest once became a Roman emperor.

Centuries later, a stressed group of maize-heavy farmers migrated into the region, facing climate instability, disease, and declining numbers. Despite these pressures, there’s no sign of violence—instead, families stayed connected across generations, using kinship networks to survive. The research shows how cooperation, not conflict, helped communities navigate crisis.

Historian Dr. Krisztina Ilko uncovers how the Augustinian order built its power through “green” miracles: restoring barren land, healing livestock, reviving fruit trees, and taming deadly landscapes once blamed on dragons. Far from symbolic tales, these acts helped rural communities survive and gave the order legitimacy at a time when its very existence was under threat.
