President Joe Biden urged Americans on Wednesday to "stand guard" against a "dangerous" oligarchy forming under Donald Trump as he delivered a dark farewell address before stepping down next week. In a speech from the Oval Office at the end of his single term in office, the 82-year-old warned of an ultra-wealthy "tech industrial complex" that could gain unchecked power. Biden also lashed out at social media firms and warned of the dangers of artificial intelligence, saying the US must take the "lead" over China on the transformative technology, and said that "powerful forces" threatened his climate achievements.

President Joe Biden's administration on Wednesday announced a ban on Red Dye No. 3, a controversial food and drug coloring long known to cause cancer in animals. Decades after evidence first raised alarm, Red 3 is currently used in nearly 3,000 food products in the US. The decision follows a petition filed in November 2022 by the Center for Science in the Public Interest (CSPI) and other advocacy groups, which cited the "Delaney Clause" -- a provision mandating the prohibition of any color additive shown to cause cancer in humans or animals.

The decision, made by Lupa Pizza, has sparked both amusement and debate over whether the fruit topping should be used on pizza. This steep price tag sits in stark contrast to the restaurant's other pizza offerings of $17 or less.
