Physicists claim they can predict when AI will turn dangerous

Researchers say they've developed a simple mathematical formula that can predict when certain ChatGPT-like artificial intelligence (AI) chatbots will "go rogue," suddenly switching from helpful responses to potentially harmful ones. In a new study published Oct. 8 in the journal Patterns, physics professor Neil Johnson and doctoral student Frank Yingjie Huo, both at The George Washington University, show how the order in which a chatbot is given certain prompts can drastically reshape its answers, leading to "tipping points" that can send the chatbot down a rabbit hole of bad advice. However, Johnson and Huo say their formula can easily predict these tipping points.There have been horror sto...

'They cannot compete with the prices that fish factories will pay': How demand for fish meal takes priority over feeding people

Fish meal is a commercial, protein-rich product created from raw fish and their byproducts, such as the heads and bones. It tends to be made from smaller fish species, including anchovies, sardines and herring. The fish are cooked, dried and ground into a powder, and then used to feed livestock, farmed fish and pets. But it is not a straightforward market. In this excerpt from "Every Last Fish: A Deep Dive into the World of Fishes and Fishing" (Granta Books, 2025), journalist and author Rose George looks at how vast quantities of staple fish are taken from the sea off West Africa and turned into fishmeal for farming in Europe and China, instead of ending up on the plates of people in Africa....

Chinese pottery discovered in Great Zimbabwe reveals medieval African empire's vast connections spanning thousands of miles

Archaeologists digging in the medieval city of Great Zimbabwe have discovered pieces of jade-green Chinese pottery, suggesting that the enigmatic empire had long-distance connections with East Asia more than 1,000 years ago. Great Zimbabwe, located in the southeastern part of modern-day Zimbabwe, was the capital of an ancient empire that arose in southeastern Africa in around A.D. 1000. Little is known about this precolonial empire because its people did not leave a written history, but new archaeological excavations are shining a light on the enormous scale of the centuries-old civilization known for its intricate metalworking and ritual stone carvings.In the new PBS documentary "Secrets of...

(Image credit: Mr. Chung-Tat Cheung)Paleontologists in China have discovered a small Jurassic bird that was likely a land-based predator — like a carnivorous pheasant with killer claws. It had some features of birds and others of dinosaurs, suggesting that the earliest birds had a greater diversity of lifestyles than previously recognized.Jurassic birds first emerged 150 million to 148 million years ago, and fossils of them are rare, so experts are just starting to understand how early birds diversified and evolved the ability to fly. The researchers discovered the newly id...
