Lab-grown cells from the reef-building coral Acropora tenuis provide new opportunities to study bleaching, symbioses, and biomineralization.

Stable, long-term cell lines will enable scientists to study everything from coral bleaching to biomineralization, knowledge that may help protect corals from ongoing climate change.

Single-cell RNA sequencing helps to catalog the dozens of cell types present in a stony coral, including its elusive immune cells.

For the first time, scientists tracked large shark movements during hurricanes and found that tiger sharks may find the turmoil opportunistic for feeding.

In a new study, human and mouse cells recognized only one in five bacterial species collected from more than a mile below the Pacific Ocean’s surface.

Researchers use proxy indicators to confirm long-term changes to the Atlantic Meridional Overturning Circulation, which have profound implications for future climate in North America and Europe.

By analyzing how fin whale calls bounce off the seafloor, scientists can recreate ocean crust layers.

Overfishing is the biggest factor driving these species toward extinction, researchers conclude from a new study.

Blue sharks don't dive as deeply in low-oxygen waters—which become more prevalent as oceans warm—effectively pushing them into areas of high fishing pressure.

Lore has always surrounded argonauts, pelagic octopuses that build shells and travel the seas.

The discovery puts a nail in the coffin of a long-held assumption about the limits of where the essential process can occur.

The retired University of California, Santa Cruz, professor was known for his work on invertebrate reproduction, kelp ecology, and Antarctic marine life.

The newly described Ikaria wariootia was a small, wormlike creature that marked an important evolutionary step between early multicellular organisms and more complex modern animals.

Preserved DNA extracted from the rock-like digestive blobs may offer insights into whale ecology.

To help create better conservation and management plans, researchers are measuring how marine organisms move between habitats and populations.

Most know Rachel Carson for her work on the dangers of chemical pollutants, but the writer’s earlier prose took readers on a tour of a mysterious underwater world.

Understanding the dinoflagellates that regularly wreak havoc on marine and nearshore ecosystems in the Gulf of Mexico could help researchers mitigate the damage they cause.

Researchers will inject a relaxin-like hormone into sea cucumbers to boost the animals’ numbers.

A mysterious illness is causing tissue loss in many species.
