430,000-Year-Old Wooden Tools Are the Oldest Ever Found

Early hominins in Europe were creating tools from raw materials hundreds of thousands of years before Homo sapiens arrived there, two new studies indicate, pushing back the established time for such activity. From a report: The evidence includes a 500,000-year-old hammer made of elephant or mammoth bone, excavated in southern England, and 430,000-year-old wooden tools found in southern Greece -- the earliest wooden tools on record. The findings suggest that early humans possessed sophisticated technological skills, the researchers said. Katerina Harvati, a paleoanthropologist at the University of Tubingen in Germany and a lead author of the wooden-tool paper, which was published on Monday in the journal PNAS, said the discoveries provided insight into the prehistoric origins of human intelligence. Silvia Bello, a paleoanthropologist at London's Natural History Museum and an author on the elephant-bone study, which was published last week in Science Advances, concurred. The artifacts in both studies, recovered from coal-mine sites, were probably produced by early Neanderthals or a preceding species, Homo heidelbergensis. Homo sapiens emerged in Africa more than 300,000 years ago, and the oldest evidence of them in Europe is a 210,000-year-old fossil unearthed in Greece. By the time Homo sapiens established themselves in Britain 40,000 years ago, other hominins had already lived there for nearly a million years.

OpenAI Releases Prism, a Claude Code-Like App For Scientific Research

OpenAI has launched Prism, a free scientific research app that aims to do for scientific writing what coding agents did for programming. Engadget reports: Prism builds on Crixet, a cloud-based LaTeX platform the company is announcing it acquired today. For the uninitiated, LaTeX is a typesetting system for formatting scientific documents and journals. Nearly the entire scientific community relies on LaTeX, but it can make some tasks, such as drawing diagrams through TikZ commands, time-consuming to do. Beyond that, LaTeX is just one of the software tools a scientist might turn to when preparing to publish their research. That's where Prism comes into the picture. Like Crixet before it, the app offers robust LaTeX editing and a built-in AI assistant. Where previously it was Crixet's own Chirp agent, now it's GPT-5.2 Thinking. OpenAI's model can help with more than just formatting journals -- in a press demo, an OpenAI employee used it to find and incorporate scientific literature that was relevant to the paper they were working on, with GPT-5.2 automating the process of writing the bibliography. [...] Later in the same demo, the OpenAI employee used Prism to generate a lesson plan for a graduate course on general relativity, as well as a set of problems for students to solve. OpenAI envisions these features helping scientists and professors spend less time on the more tedious tasks in their professions.
