Large earthquakes on mid-ocean ridge transform faults are
commonly preceded by foreshocks[superscript 1–3] and changes in the
seismic properties of the fault zone³. These seismic precursors
could be linked to fluid-related processes[superscript 2,3]. Hydrothermal
fluids within young, hot crust near the intersection of oceanic
transform faults are probably in a...

In this study we present 42 new ⁴⁰Ar/³⁹Ar incremental heating age determinations updated age progression for the Louisville seamount trail. Louisville is the South Hawaiian‐Emperor seamount trail, both trails representing intraplate volcanism (~80 Ma to present) and being examples of primary hot spot lineaments. Our age‐progressive trend from 71 to...
Estimates of the relative motion between the Hawaiian and Louisville hot spots have consequences
for understanding the role and character of deep Pacific-mantle return flow. The relative motion between
these primary hot spots can be inferred by comparing the age records for their seamount trails. We report
⁴⁰Ar/³⁹Ar ages for...

Cordyceps is a genus of perithecial ascomycetes. It includes over 400 species
that are pathogens of arthropods and parasites of the truffle genus Elaphomyces. Based
on the morphology of cylindrical asci, thickened ascus apices and filiform ascospores,
it is classified in the Clavicipitaceae (Hypocreales), which also includes endophytes
and epiphytes...
