A new model shows that the denizens of a vast, ancient biome beneath the seafloor use barely enough energy to stay alive — and broadens understanding of what life can look like.
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.
Newly discovered worlds of microbes far beneath the ocean floor, inside old basaltic rocks, could point to a greater likelihood of life elsewhere in the universe.
Skyrocketing animal diversity a half-billion years ago was linked to spikes and dips in marine oxygen levels, according to a detailed geological study.
Researchers hope that the genes of a glowing squid can illuminate how animals evolved organs for beneficial bacteria.
Layered deposits of coral skeletons hold vast stores of environmental data from thousands of years ago, including annual records of ocean temperatures, water pollution and storm activity.
For decades, researchers have commonly assumed that higher oxygen levels led to the sudden diversification of animal life 540 million years ago. But one iconoclast argues the opposite: that new animal behaviors raised oxygen levels and remade the environment.
The legendary marine biologist discusses why she’s excited about the coming era of ocean science, the shortsightedness of maritime exploitation and diving in the Arctic in her 80s.
To develop new model organisms, scientists will have to find species that are easy to grow in the lab.
