Scientists Find Evidence That Earth's Core Is Still Leaking Hydrogen, Helium and Tungsten - NDTV

Our early Earth was a heavy metal album cover: a molten ball covered in a global lava ocean, spewing lethal gases while being pelted by the flaming space-rocks of our Solar System's violently chaotic afterbirth. Over the next 4.5 billion years of hectic cosmo-geological time, it has settled down a bit, allowing humans, lemurs, and others to emerge. A vision of this hellish ancient reality remains, (hopefully) never to be glimpsed by human eyes: our molten metallic core, blazing about as hotly as the surface of the Sun. But our core constantly sends chemical messengers up through its layers, including the space-borne ingredients of its birth, locked away for about one-third the lifetime of the Universe. This includes the hydrogen that was drawn in from the giant cloud of gas and dust that formed the Sun, which continues to ooze up from the core and turns into water in the mantle and crust – not a splashy-sloshy water, but a water trapped in minerals. Early Earth may have looked something like this.

Researchers required assistance from Danish naval divers to examine the submarine. A World War I submarine that sank nearly 110 years ago has been leaking explosive pollutants into the North Sea for decades. What’s more, ocean researchers say the problem may worsen over time—not only near the German vessel itself, but at thousands of similar shipwrecks.

In April 1917, the German submarine UC-30 was making its way through waters near Rømø after abandoning a mission to Ireland because of engine problems. The vessel had turned back toward Germany and was close to reaching home. UC-30 was carrying 18 mines and six torpedoes, leaving the submarine packed with explosives. On April 19, it struck a British mine and sank. All 27 crew members died.

UM invests in sustainable solutions for science research. One of the most important research and teaching facilities at the University of Manitoba relies on a critical and non-renewable resource: helium. The Prairie Regional Nuclear Magnetic Resonance (NMR) Facility in the Department of Chemistry helps researchers study the structure and behaviour of molecules and materials. The facility supports industrial partners and academics. It also gives University of Manitoba students valuable hands-on learning opportunities. The critical role of heliumAt the heart of the NMR facility are 4 superconducting NMR magnets. Their powerful magnetic fields must remain active at all times, even when no experiments are running. To make this happen, the magnets are cooled down to extremely low temperatures using liquid helium. This keeps the materials inside the magnets superconducting and allows their magnetic fields to remain active around the clock.
