Scientists built a new theoretical model that learns from interactions. Positive interactions strengthened connections, and negative interactions weakened connections. Model revealed that strong connections can lead to feedback loops and echo chambers. Findings extend to diverse spreading systems, from social ideas to infections to animal behavior to neural signals.
Australia’s platypus, one of the world’s most enigmatic animals, had a more exotic origin story, according to an exciting discovery by Flinders University palaeontologists.
They have described rare 25-million-year-old fossils found east of the Flinders Ranges in remote outback South Australia which show ancient platypus with well-formed teeth munched on a varied diet in huge inland lakes and rivers, probably with other critters such as ancient lungfish, flamingos and freshwater dolphins.
