North Atlantic dolphins facing shorter lifespans due to bycatch
Common dolphins in the North Atlantic are dying much younger, with female lifespans dropping seven years since the 1990s, according to a new study. Researchers analyzing stranded dolphins in the Bay of Biscay highlight bycatch from fishing as a key threat, urging better conservation measures. The findings reveal a 2.4% slowdown in population growth, signaling risks to marine ecosystems.
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.
Rare speckled lobster caught off west coast
A strikingly light-speckled lobster was caught off Sweden's west coast last week. Initially thought to be an invasive species, it turned out to be a native European lobster with a rare genetic mutation in its shell. It now resides at Havets hus in Lysekil.
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.
