Do chemicals in sunscreens threaten aquatic life? A new report says a thorough assessment is ‘urgently needed,’ while also calling sunscreens essential protection against skin cancer

Rising concern about possible environmental damage from the active ingredients in sunscreens could have ripple effects on public health if it causes people to use less of them.

The ocean is not a quiet place

The ocean is often considered a silent universe. But many recent studies highlight the importance of the soundscape for many marine species, both large and small.

Researchers identified over 5,500 new viruses in the ocean, including a missing link in viral evolution

Viruses do more than just cause disease – they also influence ecosystems and the processes that shape the planet. Tracing their evolution could help researchers better understand how viruses work.

Five years after largest marine heatwave on record hit northern California coast, many warm–water species have stuck around

The Blob, a long-lasting mass of warm water, sat off the Pacific coast of North America for years, bringing new species to formerly cold waters. What allows some to survive while others fade away?

Scientists are using new satellite tech to find glow-in-the-dark milky seas of maritime lore

When conditions are just right in some parts of the Indian Ocean, a type of bacteria will multiply and start to glow. Satellites are helping scientists study these milky seas for the first time.

Curious kids: how do gills work?

Rather than breathing in and out through the mouth, fish use a one-way system, passing water in one direction over their gills.

When hurricanes temporarily halt fishing, marine food webs recover quickly

Hurricane Harvey destroyed the fishing infrastructure of Aransas Bay and reduced fishing by 80% over the following year. This removed humans from the trophic cascade and whole food webs changed.
