Glaciers aren't sterile wastelands – they're chock-full of microscopic life.
Invisible to the eye, the microbial life in the air around us can vary depending on our environment.
Tampa Bay’s sea grass meadows need sunlight to thrive. Algae blooms block that light and can be toxic to marine life.

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.

We are only just beginning to understand the importance of this deep and hidden area of the inter-reef that supports a rich diversity of 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.

Oxygen flooded the atmosphere for the first time and then ... nothing. Or so we thought.
Coral reefs contain an intricate web of predators and prey.
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.

Algae at the bottom of the Arctic food chain relies on sea ice.
Feeding pigs seaweed could make them, us and the planet healthier without contributing to antibiotic resistance in bacteria.
Tiny chemical clues in the ocean reveal how its role as a carbon store is changing.
Going all the way back: rules for the Murray Darling Basin are in Australia’s constitution.
Public confidence in the institutions in charge of the Murray Darling Basin has plummeted – with good reason.
Dead fish are a source of food for bacteria, which then extract oxygen from the river.
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.

Algae blooms have killed hundreds of thousands of fish in the last two weeks, but what exactly are they and how do we get them under control?

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.
Cyanobacteria filled the ancient oceans and used chlorophyll to harvest the sun’s energy.
Did you recently hear news that Earth's oldest pigments were hot pink? That's not quite right. When they were in living bacteria a billion years ago, they were performing photosynthesis – and green.
Cyanobacterial blooms and algae are common in water bodies around the world. However, Australia is yet to monitor the growth of neurotoxins in our algae.
A toxic chemical produced by algae and linked to motor neuron disease has been detected in NSW rivers. Its presence - long suspected but now confirmed - could be linked to a disease hotspot in the Riverina.
The ocean is getting warmer and more acidic but changing our diet could help us cope.

Scientists and government agencies have been studying biofuel production from algae for years. Research points toward a more affordable and efficient production process that recycles water.
