We preliminarily found that TikTok’s ‘For You’ feed has a harmful design. It shows users endless and repeated exposure of personalised videos, even when those have a negative effect on mental health. While TikTok has implemented measures to mitigate this risk, we consider them insufficiently effective and call for readjustment. 🔗link.europa.eu/Tpc7kc

DOJ LAUNCHES SUPER INTELLIGENCE TASK FORCE ⬇️ @POTUS Trump has made clear that “America stands at the forefront of a new technological revolution in intelligence,” and the Department will be a leader in safeguarding against malicious SI actors. “The SI Task Force at the Department of Justice will facilitate our partnership with SI Force Chair Jay Clayton as we ensure critical SI technologies serve the American people and are not manipulated by bad actors at home or abroad. The Department of Justice will continue identifying and prosecuting individuals whose use of SI violates the law, including by maliciously targeting American taxpayers, critical U.S. infrastructure, or other aspects of our national security.” -@AGToddBlanche Read more about the DOJ-SITF here: justice.gov/opa/pr/departmen…

External debt of developing countries jumped 5.5% to a record $9.4 trillion in 2025, the fastest pace since 2021, and about four times the 2022–24 average. Access to international finance has improved, but the price of finance has not. Read #IDR2026 ➡️ openknowledge.worldbank.org/…

Flying high! Today, our X-59 quiet supersonic X-59 aircraft traveled from Birmingham, Alabama, to Daytona Beach, Florida. The aircraft aims to fly faster than sound with just a gentle thump rather than a sonic boom — helping usher in a new era of faster air travel. We're prepping to feature X-59 at MAX POWER and will provide updates soon!
