In winter 2023-24, the Great Lakes’ ice cover was near record lows, peaking at just 16%. Researchers explain how diminishing ice could have consequences for fisheries, and how species are evolving.

The microbiome and its signature smells are crucial for most organisms, whether human, insect or plant. The silent signals sent by the microbiome are essential communications that influence behaviour.
Coral reefs are hotspots of productivity in otherwise nutrient-poor parts of our oceans.

To fully understand the extent of climate-related dangers the Arctic – and our planet – is facing, we must focus on organisms too small to be seen with the naked eye.

Arctic sea ice algae contaminated with microplastics have serious consequences for ecosystems and the climate.
Diazotroph (Trichodesmium) bloom in the Coral Sea, captured on 1 September 2019 by the Landsat 8 satellite. The interaction between the physics and biology of the ocean is manifested in these green filaments that snake through the currents.

The ocean absorbs a quarter of the CO₂ emitted by humans, thanks in particular to phytoplankton, including diazotrophs. Knowing how to model them is crucial to understanding the ocean’s role in climate.

Nutrient pollution fouls lakes and bays with algae, killing fish and threatening public health. Progress curbing it has been slow, mainly because of farm pollution.
TRAPPIST-1e is a rocky exoplanet in the habitable zone of a star 40 light-years from Earth and may have water and clouds, as depicted in this artist’s impression.
