    An ancient swimming revolution in the oceans may have never happened

    Swimmers may not have suddenly dominated the oceans during the Devonian Period after all: New analyses suggest they took over much more gradually.

    Bird poop helps keep coral reefs healthy, but rats are messing that up

    Eradicating invasive rats from islands may help boost numbers of seabirds, whose droppings provide nutrients to nearby coral reefs.

    Here’s what narwhals sound like underwater

    Scientists eavesdropped while narwhals clicked and buzzed. The work could help pinpoint how the whales may react to more human noise in the Arctic.

    The Chicxulub asteroid impact might have set off 100,000 years of global warming

    About 66 million years ago, the Chicxulub asteroid impact set off 100,000 years of global warming, an analysis of oxygen in fish fossils suggests.

    Bull sharks and bottlenose dolphins are moving north as the ocean warms

    Rising temperatures are making ocean waters farther north more hospitable for a variety of marine species.
