source:resource worldE-Tech Resources Inc. [TSXV-REE; FSE-K2I] reported the successful completion of its trenching and sampling program at the Eureka project in Namibia. The program revealed significant rare earth oxide mineralization across multiple locations within Exclusive Prospecting License (EPL) 6762.Highlights: The trenching program results continue to confirm the company’s new exploration model. Early results support the concept of a large-scale, stratigraphic, and structural corridor within the Eureka Dome which hosts the rare earth mineralization.Four out of the five new targets con...

source:phys.orgCerium is a rare Earth metal that has numerous technological applications, for example, in some types of lightbulbs and flat-screen TVs. While the element is rare in Earth's crust, it is slightly more abundant in the universe. However, much is unknown about how it is synthesized in stars.Now, in a new study published in Physical Review Letters, the n_TOF collaboration at CERN investigates how cerium is produced in stars. The results differ from what was expected from theory, indicating a need to review the mechanisms believed to be responsible for the production of cerium—an...
