US Secretary of Defense Pete Hegseth has said an American submarine sank an Iranian warship in the Indian Ocean.
Washington says it's the first time since the Second World War it's used a torpedo to sink an enemy vessel.
Also on the programme: we gauge the scale of the attacks inside Iran by speaking to a resident in Tehran and verifying video footage; and a look at a new AI model, trained on the DNA of over 100,000 species, that is capable of designing new genomes.
