A groundbreaking study reveals that Hawaiian volcanic rocks contain core material, lending weight to a previously held theory about Earth's structure. This finding indicates that the core engages in more exchange with the mantle than previously thought, particularly evidenced by ruthenium isotopes. The research highlights the substantial flow of mantle material from the core-mantle boundary to the surface, fundamentally enhancing our grasp of the Earth's deep interior dynamics.

The United States is developing a revolutionary nuclear-powered network deep beneath the ocean, capable of recharging drone submarines for almost thirty years without the need for resupply. This groundbreaking defense initiative utilizes strontium-90, a radioactive by-product, as its energy source. Led by Zeno Power, this project not only enhances national security but also opens doors for future scientific explorations.
