Abstract: The mechanisms and processes by which subducted slab interacted with mantle plume remain controversial, as direct observation of such interaction is difficult to impossible. Compositional heterogeneity of large igneous provinces (LIPs) additionally makes plume-slab interaction hard to detect. Oxygen isotopes are sensitive enough to trace the source of magmas. Here we provide evidence for plume-slab interaction mainly based on in situ zircon Hf-O isotope analyses, as well as whole-rock elemental and Sr-Nd-Hf isoto...

HOUSTON:Scientists have compared variants of the novel coronavirus and the closely related 2002-03 SARS pandemic virus and found the differences in their respective infection mechanisms, an advance that partly explains why COVID-19 transmission is much more difficult to control. The findings, published in the journal Frontiers in Molecular Biosciences, noted that both the COVID-19 virus — SARS-CoV-2 — and the SARS coronavirus are very similar in sequence and almost identical in structure. However, compared to the SARS virus, which caused over 750 deaths and more than 8400 known cases of i...

Key variants help explain the differences between viruses that cause COVID-19 and SARS An effort led by Lin Li, Ph.D., assistant professor of physics at The University of Texas at El Paso, in collaboration with students and faculty from Howard University, has identified key variants that help explain the differences between the viruses that cause COVID-19 and Severe Acute Respiratory Syndrome (SARS). A team comprised of researchers from UTEP and the historically Black research university in Washington, D.C., discovered valuable data in comparing the fundamental mechanisms of Severe Acute Resp...
