The interaction of magma with continental crust at convergent margins is fundamental to
understanding if and how continents grow. Isotopic and elemental data constrain the
progressive stages of development of the magmatic underpinnings of the long-lived
Aucanquilcha Volcanic Cluster (AVC), situated atop the thick continental crust of the

Background: Prenatal mercury (Hg) exposure is associated with adverse child neurobehavioral
outcomes. Because Hg can interfere with placental functioning and cross the placenta to target the
fetal brain, prenatal Hg exposure can inhibit fetal growth and development directly and indirectly.
Objectives: We examined potential associations between prenatal Hg exposure assessed...

We report ³He/⁴He for 150 mid-ocean ridge basalt (MORB) glasses from the Southeast Indian
Ridge (SEIR). Between 81°E and 101°E ³He/⁴He varies from 7.5 to 10.2 R[subscript A], encompassing more than half the
MORB range away from ocean island hot spots. Abrupt transitions are present and in one case the...

Stressors associated with human activities interact in complex ways to affect marine ecosystems,
yet we lack spatially explicit assessments of cumulative impacts on ecologically and
economically key components such as marine predators. Here we develop a metric of
cumulative utilization and impact (CUI) on marine predators by combining electronic tracking...

Root rot diseases of bean (Phaseolus vulgaris L.) are a constraint to dry and snap bean production. We developed the RR138 RI mapping population from the cross of OSU5446, a susceptible line that meets current snap bean processing industry standards, and RR6950, a root rot resistant dry bean with small...
