A team of researchers from the Istituto Nazionale di Geofisica e Vulcanologia, in Italy, has found evidence showing that magma pressure had begun building up deep in Mt. Etna's reservoir several months before the 2018 eruption. ...
The Alpha Magnetic Spectrometer (AMS) collaboration, a large group of researchers from CERN and other institutes worldwide, has recently presented a series of precision measurements of the properties of cosmic Helium isotopes ...
Analyses show that gases found in microscopic inclusions in diamonds come from a stable subterranean reservoir at least as old as the Moon, hidden more than 410 km below sea level in the Earth's mantle.
