Researchers from a German research center and a Scottish university have created an artificial‑intelligence system that can analyze dinosaur footprints and suggest the most likely trackmaker. Trained on thousands of real fossils and millions of simulated tracks, the algorithm focuses on eight key foot characteristics and operates without human‑assigned labels. In tests the AI agreed with expert classifications about ninety percent of the time, offering a neutral, mathematical aid for paleontologists. The open‑source tool is available on GitHub and could expand as more scientists contribute data, potentially shedding new light on dinosaur‑bird evolution. Lire la suite

X, the platform formerly known as Twitter, has released its recommendation algorithm on GitHub, promising weekly transparency updates. The open‑sourced code shows a machine‑learning pipeline that weighs user engagement, filters out blocked or harmful content, and ranks posts for relevance and diversity. While the move fulfills a promise by owner Elon Musk, the platform continues to face criticism for past incomplete disclosures, a $140 million EU fine under the Digital Services Act, and investigations into its Grok chatbot’s role in generating sexualized images. Observers view the latest openness as potentially more theater than substantive change. Lire la suite

Instagram has announced it now has 3 billion monthly active users. To keep growth momentum, the platform will test features that let users fine‑tune the algorithm behind Reels and other feeds, including toggling interest topics and a redesigned navigation bar that emphasizes direct messages. The rollout comes as Meta faces antitrust scrutiny over its acquisitions of Instagram and WhatsApp, with internal tensions highlighted between Instagram’s rise and Facebook’s declining appeal among younger users.

A potential deal to keep TikTok operating in the United States past the current deadline is moving forward. The arrangement would involve a consortium of U.S. firms, including Oracle, Silver Lake and Susquehanna International, taking control of the platform's American operations while ByteDance retains a minority board seat. The transition may be handled through an app update rather than a new download, but a new algorithm trained on fresh data is expected. Experts warn that technical hurdles and policy concerns could jeopardize the effort, leaving the platform's future in flux. Lire la suite
