Beneath the floor of the South Pacific, one of the most nutrient-poor places in the ocean, researchers sampled sediments laid down about 100 million years ago, in the age of dinosaurs. When incubated with food, the microbes inside started feeding and multiplying again. They had survived all that time in a near-dormant state.
In 2022, a young tagged bar-tailed godwit flew from Alaska to Tasmania in about 11 days of nonstop flight, covering 13,560 km without eating, drinking or landing. Before departure, these birds pile on huge fat reserves and shrink their digestive organs, which are useless during the journey.
To escape rivals, a dung beetle rolls its ball of dung in a straight line. At night, it holds its course using the glowing band of the Milky Way. In a planetarium, researchers showed that beetles rolled straight under a starry sky but wandered aimlessly when the galaxy was switched off. It was the first animal known to navigate this way.
