Last week, the Trump Administration ordered Anthropic to cut off access to its most advanced AI models — Mythos 5 and the pared-down public version, Fable 5 — from foreign nationals due to reported security weaknesses in Fable's safeguards.

One of those companies is Mozilla, which said Mythos identified about 270 bugs in its Firefox browser that had slipped through previous reviews.

Marketplace’s Meghan McCarty Carino spoke with Mozilla chief technology officer Raffi Krikorian about the government essentially hitting a kill switch on the system.

So this episode, we team up with Germany-based reporter Sam Baker from the DW podcast “Living Planet.” We follow carbon dioxide from its source at a cement plant, all the way to its final resting place under the North Sea. And we look beyond the hype to see if Carbon Capture and Storage could be a real climate solution. Or just another way for the fossil fuel industry to keep on drilling.
