Summary

This episode of 7 Days of Science presents a roundup of recent scientific discoveries. The first story details the observation of an extremely fast-spinning neutron star in a binary system, spinning 716 times per second. Next, a study evaluates the infinite monkey theorem, calculating the probability of a chimpanzee typing Hamlet before the heat death of the universe. The main paleontology story is the discovery of a new, possibly the largest, terror bird from Colombia, estimated to weigh 156 kg. Another fossil find is the oldest known tadpole, dating to the mid-Jurassic, providing insights into frog evolution. The episode also covers the identification of an 800-year-old ‘Well-man’ from a Norse saga using ancient DNA, and briefly mentions other topics like intensive fishing and carbon storage. The video is presented in an engaging and accessible style, with clear explanations of the scientific context for each story.
