Week in Science: Should we abandon pi?

The biggest science stories this week                    

May 8—Pi feels like such a, well, constant in the world of math. But some mathematicians have been calling for an end to the irrational number's reign. Plus, updates on the fatal outbreak of hantavirus on a cruise ship, and see the huge trove of photos NASA just released from the Artemis II mission.

Lastly: happy 100th birthday, David Attenborough!
