Helium Isotopes Point To New Sources Of Geothermal Energy. ScienceDaily . Retrieved June 4, 2025 from www.sciencedaily.com / releases / 2007 / 11 / 071129183725.htm ...

New techniques and refinements of older ones are needed to reach <1 K for quantum-computing cooling.

“We showed that the core-mantle diffusion quantitatively transports tungsten and helium isotopes to almost exactly match the geochemistry of the hotspot islands,” Korenaga told the News. In rocks, ...

Natural helium occurs as two isotopes, helium-4 (4He) and helium-3 (3He.) Typically, helium-4 is more abundant in Earth’s crust, whereas helium-3 is more abundant in the mantle below.

Woods Hole Oceanographic Institution geochemist Forrest Horton discovered helium isotope ratios in olivine samples from the Baffin lava fields that had up to 50 times the concentrations found in ...

Rock outcrops and other landforms around Yellowstone National Park provide records of three cycles of explosive volcanism that occurred over the past 2.1 million years. Although no magmatic ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic ...

Both isotopes of helium share one bizarre property: superfluidity. Below 4.2 K, helium-4 becomes a liquid but then at 2.17 K it is a superfluid, allowing it to flow without losing kinetic energy. This ...

However, helium, and especially the ratio between helium’s two naturally-occuring isotopes ( 3 He and 4 He), can tell us about the source of the helium.Within the Earth, helium can come from two ...

AFTER the discovery by Urey of the isotope of hydrogen of mass 2 (deuterium) and its concentration by electrolysis, it was natural to examine whether any other stable isotopes of hydrogen, and ...
