Science correspondent Allan Blackman looks at a new debate among zoologists about whether it's time to change scientific names that are now problematic - like the Hitler beetle or the Trump moth. Astronomers have witnessed the creation of rare heavy elements in the aftermath of a collision between two neutron stars that were booted out of their home galaxy about a billion light years away - it's helping fill some gaps on where our elements come from. And a long-beaked echidna named after Sir David Attenborough has been captured on film for the first time in 60 years.
