Left/Southern Ocean/Right/Southern Ocean on map/Image: AI Generated As the world searches for ways to remove carbon dioxide already accumulating in the atmosphere, ocean iron fertilisation (OIF) has emerged as one of the most debated climate intervention strategies. The idea is deceptively simple: adding tiny amounts of iron to iron-poor parts of the ocean stimulates the…
Communities dig water-harvesting pits to restore degraded land and improve soil moisture in the Sahel. For decades, the Sahel has symbolised environmental decline. Stretching nearly 5,900 kilometres across Africa from Senegal on the Atlantic coast to Sudan on the Red Sea, this semi-arid belt has endured recurring droughts, advancing desertification and repeated crop failures since…
Ecosystems work with each other no matter how far or disconnected they are. Animals and birds have impacts on each other’s lives and deaths. According to a new study, invasive rats on tropical islands are creating winners and losers among tiny underwater animals near the bottom of the food chain that inhabit surrounding coral reefs….
Most animals leave behind waste that quickly disappears into the landscape. But along Europe’s sandy tidal flats, one marine worm has adopted a remarkably different approach. Instead of scattering its droppings across the beach, it carefully stacks them into tall, coiled towers that seem to defy gravity. These delicate spirals have fascinated naturalists since the…
Specimen of Chondrosia reniformis transplanted into the harbor. Image credit: Carlota Escarré Scientists transplanted 42 sea sponges into a polluted Spanish marina, where 91.7 per cent of one hardy species survived for 455 days and began creating mobile clones.The study, published in Frontiers in Marine Science, shows that the chicken kidney sponge (Chondrosia reniformis) can…
Spruce and birch trees are seen tilting along the edge Stevens Pond on the University of Alaska Fairbanks campus on Sept. 18, 2022. Thick green tree canopies across northern forests act as giant sunshields, keeping permafrost cool enough to hold 59 billion tonnes of carbon safely in the ground.The discovery reveals that the forest canopy…
At first glance, a sheet of folded paper may seem far removed from advanced engineering. But for Japanese student Kuribayashi, origami became the starting point for a scientific investigation into how structures move. The student from Sapporo Kaisei Secondary School studied the complex folding patterns of a ladybug wing, exploring how its delicate design allows…
The rapid expansion of artificial satellite constellations is changing the appearance and accessibility of the night sky, creating a new challenge to the field of astronomy. For decades, the primary concern for astronomers was light pollution present on earth, but the introduction of large-scale telecommunication networks, such as SpaceX’s Starlink, has introduced a new form…
A research team led by University of Michigan isolated and grew more than 200 kinds of fungi from the deep subsurface (Credit: Quinn Moon University of Michigan) Scientists drilling 1,640 feet beneath Michigan have discovered 689 kinds of fungi living in water that last touched the surface 11,000 years ago.The University of Michigan study shows…
For decades, the extinction of the dinosaurs has usually been pictured as a slow collapse. An asteroid struck Earth, sunlight faded behind dust, temperatures changed, and ecosystems gradually unravelled. That broad sequence still stands, yet a new study argues that the first chapter of the catastrophe may have unfolded far more quickly than many imagined….
