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.

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.
The right kind of algae can be converted to biofuel, and there are potential side benefits for carbon capture.
The climate change-mitigating dream turns out to be a green damp squib.
Nitrogen and phosphorus are polluting US waters, creating algae blooms and dead zones. New research confirms that voluntary steps are failing in the Gulf of Mexico and unlikely to work in Lake Erie.
Melting ice from Antartica could feed vast plankton blooms, trapping carbon in the ocean. To understand this complex mechanism, researchers looked at volcanoes deep under glaciers.
A new study suggests the benefits of a boost to marine plant growth from increased carbon dioxide will be cancelled out by the increased stress to fish species.
Four organisms that show nature isn’t so easily categorised.
Just like humans, corals live with myriad microscopic organisms. We are just starting to understand this unseen world.
Populations of certain species collapse long before a wider ecological disaster, says new research.
They give us part of the air we breathe but microscopic phytoplankton can also be toxic. They are also on the move thanks to climate change so a new Australian database hopes to monitor any changes.
An estimated one-third of corals have now died in the parts of the Great Barrier Reef hit hardest by bleaching, meaning recovery could take years or even decades.
The economics of making biofuels from algae no longer add up, but a lesson from the oil industry could make them viable.
The bleaching hitting the Great Barrier Reef not only harms corals. As these close-up photos show, it also deprives many other species of a home and livelihood.
We are only just starting to understand the potential of microscopic algae as forensic evidence.
We have the technology to make oil from algae, rather than digging up crude oil from organisms that lived billions of years ago. But bringing it to market will take a force of economic and political will.
Smart dirt is made up of those germs clinging to the surfaces around us that have become resistant to the chemicals normally used to get rid of them.
Algae isn’t just found in your garden pond or local river. Sometimes it explodes into vast “blooms” far out to sea, that can be the size of a small country. Such algal blooms can match even a rainforest…
