CPAC Hungary, the Budapest edition of the Conservative Political Action Conference, gathered American and European conservative activists, politicians, and commentators to discuss what organizers called the decline of Western civilization.

Hungary’s prime minister Viktor Orbán was a prominent speaker, and some remarks echoed the “great replacement” language while emphasizing national sovereignty and cultural preservation.

Sarah Ogilvie’s The Dictionary People tells the story of the people who built the Oxford English Dictionary by collecting words, quotations, and regional usages. Ogilvie, a linguist, shows that the OED was not made by a single team in isolation but by thousands of volunteers who sent slips of paper and examples from newspapers, books, and everyday speech.

Researchers report that reef-dwelling hogfish have light-sensitive cells embedded in their skin, allowing the animals to sense brightness and adjust their colour without relying solely on eyes. The study, published in Nature, shows this skin-based photoreception can continue to influence colour change even after death. Hogfish live in Atlantic reefs and can shift hues in milliseconds. Those rapid changes aid camouflage, social signalling and may help with temperature regulation and attracting mates.
