Published in Mycology, research by an international team details the isolation (guided by molecular networking and SMART), structural elucidation, and biological evaluations for metabolites from the marine-derived fungus Aspergillus sydowii LF51, including new enantiomers (±)-aspersydonol A (1a/1b), aspersydonol B (2), and 12 known analogs (3–14).
New study reveals that corals in the Gulf of Aqaba have withstood four consecutive and intensifying marine heatwaves, including the world’s most extreme 2024 event, without suffering mass bleaching — a resilience unmatched elsewhere. This is important because coral reefs globally are collapsing under rising ocean temperatures, threatening ecosystems and human livelihoods. The Gulf of Aqaba may represent one of the planet’s last natural refuges for reef survival, offering a crucial model for understanding resilience and underscoring the urgency of protecting this unique ecosystem before even it reaches its limits. New study reveals resilience of Red Sea corals in the face of intensifying climate threats.
The kelp forest is ephemeral, yet foundational. Fronds of this fast-growing giant seaweed come and go with the seasons, storms and waves, supporting communities of fish, invertebrates and even mammals wherever they emerge. As dynamic as they are in the ocean, kelp forests are also essential for its nearby shoreline communities, as fronds of this seaweed wash up on the beach, providing sustenance for invertebrates and serving as the foundation of beach food webs.
Think your multitasking is impressive? A new study reveals that wild octopuses use their arms with incredible complexity. Each of the eight limbs can perform any type of movement, but clear patterns emerged: front arms explore, back arms support movement. Even more impressively, individual arms can perform multiple actions at once – and coordinate across several limbs – showcasing the octopuses’ remarkable motor control in natural settings.
