Researchers create glowing probe to track ocean microbe sugar breakdown
A team of scientists has invented a fluorescent molecular probe that lights up when marine microbes degrade sugars, revealing key processes in the ocean's carbon cycle. This tool allows real-time observation of how algae and bacteria interact in breaking down complex carbohydrates. The breakthrough, detailed in the Journal of the American Chemical Society, promises deeper insights into carbon storage and release in marine ecosystems.
European institutions launch campaign for International Coccolithophore Day
AI에 의해 보고됨
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.
Antarctic robot reveals thousands of icefish nests in Weddell Sea
Scientists using a robotic explorer have discovered over a thousand organized fish nests beneath Antarctica's Weddell Sea, exposed after a massive iceberg calved in 2017. The nests, built by yellowfin noties, form geometric patterns on the seafloor and highlight a thriving ecosystem in extreme conditions. This finding underscores the need to protect the region as a marine sanctuary.
Deep-Sea Worms Tolerate High Arsenic
Researchers revealed on September 6, 2025, the discovery of deep-sea worms capable of tolerating high levels of arsenic, expanding knowledge of extremophile adaptations. This finding uncovers new biological mechanisms for toxin resistance. It was reported alongside other marine science updates.
