In this episode:00:46 Optical clocks at seaOptical atomic clocks are the most precise timekeeping devices on the planet, but these devices are huge and difficult to work with, limiting their use outside of the lab. Now, researchers have developed a portable optical clock and demonstrated its robustness by sending it on a perilous sea journey. The team hope that this work will pave the way to more practical uses of optical clocks, such as on satellites where they could help improve the accuracy of GPS technologies.Research Article: Roslund et al.News and Views: Robust optical clocks promise stable timing in a portable package09:34 Research HighlightsEvidence of ritual burning of the remains of a Maya royal family, and the first solid detection of an astrophysical tau-neutrino.Research Highlight: Burnt remains of Maya royalty mark a dramatic power shiftResearch Highlight: Detectors deep in South Pole ice pin down elusive tau neutrino11:52 How marsupial gliding membranes evolvedSeveral marsupial species have evo
