00:45 What ancient DNA has revealed about Rapa Nui’s past

Ancient DNA analysis has further demonstrated that the people of Rapa Nui did not cause their own population collapse, further refuting a controversial but popular claim. Rapa Nui, also known as Easter island, is famous for its giant Moai statues and the contested idea that the people mismanaged their natural resources leading to ‘ecological suicide’. Genomes sequenced from the remains of 15 ancient islanders showed no evidence of a sudden population crash, substantiating other research challenging the collapse idea.

19:29 A macabre parasite of adult fruit flies

Despite being a hugely-studied model organism, it seems that there’s still more to find out about the fruit fly Drosophila melanogaster, as researchers have discovered a new species of parasitoid wasp that infects the species. Unlike other parasitic wasps, this one lays its eggs in adult flies, with the developing larva devouring its host from the inside. The miniscule wasp was discovered by chance in an infected fruit fly collected in a Mississippi backyard and analysis suggests that despite having never been previously identified, it is widespread across parts of North America.
