Thanks for posting this gem. We have disappearing coffee mugs that threatens their population and the entire fork collection went extinct in one unchronicled event.
One of my absolute favorite studies.
70 teaspoons placed in tearooms around the institute & observed weekly over 5 months. 80% of spoons disappeared; spoon halflife~81 days. Communal room halflife lower than in specific labs. 250 spoons annually required to maintain 70 spoon population.

Selection and transmission of the gut microbiome alone can shift mammalian behavior - Nature Communications
Here, the authors present evidence that the gut microbiome alone, without changes in the host genome, can shape how animals respond to selection, identifying a bacterium and its metabolite that independently reduce mouse locomotion.

Yes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.
