Dr Ciaccio (not a doctor) talks about new info on the social lives of Tyrannosaurus Rexes, they might have had more friends than we thought, plus reportedly they were slow AF.

In Muon news two particle accelerators, CERN in Switzerland and Fermilab in Illinois, are racing to confirm new data that might upend particle physics as we know it, or never quite understood in the first place. Finally, there's a remote control helicopter on Mars and I still don't have one.
