DNA and Dung Beetles

The video covers various scientific topics, starting with an ambitious plan to catalog all living organisms on Earth by the end of the century. It discusses the challenges and progress in taxonomy, including the discovery of new species. The video then explores the unique navigation abilities of dung beetles using the Milky Way. It also delves into a historical radiation event in 775 CE, debating its possible causes. Finally, it highlights the discovery of DNA quadruplexes, which could have implications for cancer research.
