The moons orbiting Jupiter and Saturn appear to have subsurface oceans — tantalizing targets in the search for life beyond Earth. But it’s not clear why these seas exist at all.
How Quantum Physicists Explained Earth's Weather Patterns
By treating Earth as a topological insulator — a state of quantum matter — physicists found a powerful explanation for the movements of the planet’s air and seas.
An Explorer of Abyssal Depths Looks to Oceans on Other Worlds
The marine geochemist Chris German brings decades of experience studying seafloor hydrothermal vents to NASA’s preparations for visits to other ocean worlds in our solar system.
Random Search Wired Into Animals May Help Them Hunt
The nervous systems of foraging and predatory animals may prompt them to move along a special kind of random path called a Lévy walk to find food efficiently when no clues are available.
How Jurassic Plankton Stole Control of the Ocean’s Chemistry
Only 170 million years ago, new plankton evolved. Their demand for carbon and calcium permanently transformed the seas as homes for life.
Rapid Oxygen Changes Fueled an Explosion in Ancient Animal Diversity
Skyrocketing animal diversity a half-billion years ago was linked to spikes and dips in marine oxygen levels, according to a detailed geological study.
Scientists Discover Nearly 200,000 Kinds of Ocean Viruses
New work raises the estimated diversity of viruses in the seas more than twelvefold and lays the groundwork for a better understanding of their impact on global nutrient cycles.
On Waste Plastics at Sea, She Finds Unique Microbial Multitudes
