Volcanoes under the ice: melting Antarctic ice could fight climate change

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.
We think of coral reefs as a diverse ecosystem, but each coral is an entire and complex microworld of organisms imperceptible to our eyes. Floriaan Devloo-Delva

What we have in common with corals and their unexplored microbial world

Just like humans, corals live with myriad microscopic organisms. We are just starting to understand this unseen world.

Collecting data to help protect Australia’s waters from toxic algal blooms

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.
Bleached coral can take on luminously beautiful pink and purple hues - but don’t be deceived, these corals are under stress. Justin Marshall/coralwatch.org

Visualising algae-eating viruses from space

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…

Insomniac algae more productive

Algae can produce up to 700% more compounds when tricked to stay awake, according to new research conducted by Vanderbilt…
