00:46 Optical clocks at sea

Optical 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.

11:52 How marsupial gliding membranes evolved

Several marsupial species have evolved a membrane called a patagium that allows them to glide gracefully from tree to tree. Experiments show that mutations in areas of DNA around the gene Emx2 were key to the evolution of this ability, which has appeared independently in multiple marsupial species.
