Deep Mantle, Hidden Water: New Iron Minerals Could Store Earth's Ancient Water

A new Nature Geoscience study suggests Earth’s mantle could hide an ancient water reservoir. In lab experiments simulating conditions about 1,800 miles beneath the surface (roughly 2 million atmospheres and 2,500°C), scientists formed two iron oxyhydroxide minerals, Fe5O12Hx and Fe7O12Hx, that can trap water across deep-mantle conditions and may host primordial or recycled water near the core–mantle boundary. While it’s not yet proven these minerals occur naturally, the findings offer a potential deep-Earth water store and shed light on the mantle’s role in Earth’s water cycle and interior structure.

Earth’s Core Could Hold 45 Oceans of Water, New Study Suggests

A Nature Communications study led by Motohiko Murakami suggests hydrogen from early Earth became chemically bound inside the metallic core as iron hydrides, not as free gas or water. If hydrogen accounts for up to about 0.36% of the core’s mass, this could translate to roughly 45 oceans’ worth of water, implying Earth’s surface water may be just a fraction of a much larger deep-water inventory formed during planet formation.

Observation of Massless Dirac Electrons in Four Dimensions

Physicists have successfully isolated "massless" Dirac electrons, revealing their weightless nature and unprecedented velocity, while also uncovering their significant role in topological materials. This achievement required creating extreme conditions and specific spin manipulation. The study broadens our understanding of quantum behavior and opens new doors for the development of cutting-edge electronic devices and materials, marking a monumental leap forward in harnessing the potential of quantum physics for real-world applications.

"Unveiling the Truth: Is Hydrogen a Metal?"

Physicists have long theorized that metallic hydrogen could exist under certain conditions, and recent research has made progress in creating it. By subjecting hydrogen to extreme pressures using a diamond anvil cell, scientists have observed the transition of hydrogen from a gas to a solid state, and potentially into a metallic state. Metallic hydrogen is believed to exist in the interior of Jupiter and could have applications as a superconductor. However, the challenges of achieving and studying metallic hydrogen make it unlikely to be used in industry anytime soon, leading researchers to focus on hydrides as a more feasible alternative.
