European institutions launch campaign for International Coccolithophore Day

Five European research institutions have announced an initiative to establish October 10 as International Coccolithophore Day, highlighting the crucial role of these microscopic plankton in regulating Earth's climate. Coccolithophores, tiny algae smaller than dust grains, capture carbon dioxide, produce oxygen, and form geological records of climate history. The campaign aims to raise awareness of their impact on ocean ecosystems amid climate change threats.

Researchers have discovered that octopuses can use their suckers to sense harmful microbes on surfaces such as crab shells or their own eggs. This finding was highlighted in a science discussion on September 12, 2025, revealing new insights into cephalopod sensory capabilities. The ability allows octopuses to avoid contaminated food or protect their offspring effectively.

Corals may be adapting to rising ocean temperatures

A new study suggests that some coral species are showing signs of adaptation to warmer waters caused by climate change. Researchers observed corals in Hawaii surviving higher temperatures than expected. This finding offers a glimmer of hope amid widespread coral bleaching events.

A new study warns that proposed deep-sea mining could endanger 30 species of sharks, rays, and chimaeras whose habitats overlap with mining zones. Nearly two-thirds of these species are already threatened with extinction from human impacts. Researchers from the University of Hawai'i at Mānoa highlight risks from seafloor disruptions and sediment plumes.
