How Microbes Use Earth's Ancient Carbon
1+ day, 19+ hour ago (583+ words) Hydrothermal vents on the ocean floor release carbon dioxide that is many million years old. This old carbon originates from the Earth's interior, and it escapes either directly from the Earth's mantle or is produced when rocks that contain limestone…...

Erosion Of Iceberg A-23A Sparks A Surge Of Microscopic Life
3+ day, 18+ hour ago (495+ words) Iceberg A-23A has had a more eventful run than most of the large Antarctic icebergs that have calved from the continent's ice shelves in recent decades. Over its winding, forty-plus-year journey, the "megaberg" spent decades grounded in the Weddell Sea before…...

Antarctica Sits Above Earth’s Strongest Gravity Hole
1+ week, 2+ day ago (347+ words) Gravity feels reliable " stable and consistent enough to count on. But reality is far stranger than our intuition. In truth, the strength of gravity varies over the Earth's surface. And it is weakest beneath the frozen continent of Antarctica after…...
Ancient Rocks Reveal Evidence Of The First Continents And Crust Recycling Processes On Earth
1+ week, 2+ day ago (751+ words) The study, published Feb. 4 in the journal Nature, is based on chemical analyses of ancient zircons found in the Jack Hills of Western Australia. These sand-sized grains preserve the only direct records of Earth's first 500 million years and offer rare…...
Aurora Vent Field Is A Hotspot For Microbial Hydrogen Oxidation In The Arctic Ocean
1+ week, 6+ day ago (227+ words) Here, we use a metagenomic approach to, for the first time, assess the genome-resolved microbial energy conservation potential within hydrothermal deposits and sediments from the ice-covered, extraordinarily H2-rich Aurora Vent Field in the Arctic Ocean. Community-wide analysis revealed broad taxonomic…...
