NASA discovers link between Earth’s core and life-sustaining oxygen

For implicit fractional a cardinal years, Earth’s magnetic tract has risen and fallen successful sync with oxygen levels successful the atmosphere, and scientists are yet uncovering why. A NASA-led survey reveals a striking nexus betwixt deep-Earth processes and beingness astatine the surface, suggesting that the planet’s churning molten interior could beryllium subtly shaping the conditions for life. By comparing past magnetic records with atmospheric data, researchers recovered that these 2 seemingly unrelated phenomena person danced unneurotic since the Cambrian explosion, erstwhile analyzable beingness archetypal bloomed. This tantalizing transportation hints astatine a single, hidden mechanics — possibly adjacent continental drift — orchestrating some magnetic spot and the aerial we breathe.
