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.
Public confidence in the institutions in charge of the Murray Darling Basin has plummeted – with good reason.
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.
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.
