Scientists uncover the 2.3-billion-year-old secret that helped keep Earth habitable

Scientists may have solved a 2.3-billion-year-old mystery about how Earth maintained enough oxygen to support life. Ancient rocks reveal that phosphorus recycling in the oceans created a self-sustaining cycle that helped keep oxygen levels high, even as the planet underwent dramatic environmental changes. The discovery challenges assumptions about Earth's early atmosphere and raises new questions about why complex life took so long to emerge.

Scientists uncover a hidden map of the brain with 539 distinct regions

Scientists have uncovered a hidden layer of organization in the brain by creating the first detailed 3D map of its lipids, the fatty molecules essential for brain structure and communication. By analyzing millions of measurements from mouse brains, researchers identified 539 distinct chemical zones, revealing patterns and boundaries that traditional brain maps have missed. Surprisingly, even white matter, once thought to be relatively uniform, contains a complex patchwork of chemically distinct regions.
