Rivers are among the most embattled ecosystems on Earth. Researchers are testing a new, inexpensive way to study river health by using eDNA to count the species that rivers harbor.
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.
Three pioneering technologies have forever altered how researchers do their work and promise to revolutionize medicine, from correcting genetic disorders to treating degenerative brain diseases.
Harmful algae blooms are an increasing problem in Florida. Once nutrients are in the water to fuel them, little can be done to stop the growth, and the results can be devastating for marine life.
Warmer waters, heavier storms and nutrient pollution are a triple threat to Great Lakes cities’ drinking water. The solution: Cutting nutrient releases and installing systems to filter runoff.
In the days before scuba technology, the celebrated photographer sought to capture the beauty of the reef by placing corals in an aquarium and shooting them. But under stress, they released algae.
Researchers have just discovered a new species of bacteria that cranks out a deadly toxin. In a common arrangement in the marine environment, a slug and alga both use this toxin for their own defense.
Hundreds of thousands of fish have died in low-oxygen water. Here’s what actually happened to the oxygen, and why we might see more deaths in the coming weeks.
Red tide and a blue-green algae outbreak are fouling hundreds of miles of coast, killing fish and driving tourists away from beaches. Some of the causes are natural, but human actions play a big role.
