1+ day, 4+ hour ago  (785+ words) For about 540 million years, Earth's magnetic field and the oxygen in its air have risen and fallen together. A NASA-led team has now measured that link, suggesting the planet's molten core helped create the long-term conditions necessary for complex life…...

2+ day, 22+ hour ago  (762+ words) Iron ore describes any rock or mineral deposit that contains enough metallic iron to make extraction worthwhile. These rocks appear in a surprising spectrum of colors. Some glow rusty red or deep purple, while others show striking yellow or dark…...

1+ week, 1+ day ago  (783+ words) Miners in China reported a major gold discovery. The volume of the deposit, if confirmed, would be the largest ever recorded on Earth. The conservative estimate given thus far is 1,100 short tons (about 998 metric tons), valued at approximately $83 billion. The…...

1+ week, 4+ day ago  (855+ words) Ancient magnetic records have shown that two vast, overheated regions deep inside Earth have guided the planet's magnetic field for hundreds of millions of years. The research reveals that Earth's magnetic field has been steered by the same deep features…...

1+ week, 5+ day ago  (791+ words) Seed-sized crustacean fossils have revealed that seafloor species crossed the North Pacific five million years ago along active cold-water routes. That discovery reframes how ocean circulation linked Asia and North America during a warmer phase of Earth's climate. The evidence…...

1+ mon, 1+ day ago  (822+ words) Deep beneath the planet's surface, Earth's core behaves in a way scientists have struggled to explain for decades, with consequences for how the planet moves and protects itself." New evidence now suggests that the solid heart of Earth is softer…...
