Fast walking for just 15 minutes a day can reduce premature death by 20%, improve heart health, lower dementia risk and boost overall well-being.

"Deadliest Catch" Captain Sig Hansen reflected on dangerous decisions at sea, including ego-driven choices and a heart attack that nearly cost him everything.

An estimated 5 billion sea stars have died due to a sea star-wasting disease in oceans around the world. A team of researchers identified the cause as a bacterium known as Vibrio pectenicida.

The Schmidt Ocean Institute's ship was equipped with the ROV SuBastian, a deep-sea remotely operated vehicle used to explore the seamounts of the Pacific Ocean. During a 2024 voyage, ROV SuBastian was ...

Sick sea stars are lethargic, lose their arms and disintegrate into gooey masses. More than 90% of sunflower sea stars were killed.

Their disappearance led to unchecked sea urchin growth, which in turn destroyed extensive kelp forests—habitats called the "rainforests of the ocean" due to their biodiversity and importance for ...

Scientists say they have at last solved the mystery of what killed more than 5 billion sea stars off the Pacific coast of North America in a decade-long epidemic.

Sea star wasting is now documented around the world, and happens mostly in warmer months. Since so many sea stars were killed, that allowed their primary food source of sea urchins to flourish. There ...

Scientists say they have solved what killed more than 5 billion sea stars off the Pacific coast of North America in a decade-long epidemic.

But once sea urchin populations boomed, there was a widespread loss of kelp forests. To identify the disease, researchers ran more than 20 experiments from 2021 to 2024.
