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
central Andes...

Neogene rocks of the Deschutes basin include the middle Miocene
Columbia River Basalt Group and Simtustus Formation, and late Miocene
to early Pliocene Deschutes Formation. Assignment of Prineville
chemical-type flows to the Grande Ronde Basalt of the Columbia River
Basalt Group is based upon correlation of these lavas from their...

In the future, Earth will be warmer, precipitation events will be more extreme, global mean sea level will rise, and many arid and semiarid regions will be drier. Human modifications of landscapes will also occur at an accelerated rate as developed areas increase in size and population density. We now...

Pseudomonas protegens strain Pf-5 is a rhizosphere bacterium that suppresses soilborne plant diseases and produces at least seven different secondary metabolites with antifungal properties. We derived mutants of Pf-5 with single and multiple mutations in biosynthesis genes for seven antifungal metabolites: 2,4-diacetylphoroglucinol (DAPG), pyrrolnitrin, pyoluteorin, hydrogen cyanide, rhizoxin, orfamide A,...

OBJECTIVE: The associations of some risk factors with cardiovascular disease (CVD) are attenuated in
older age; whereas others appear robust. The present study aimed to compare CVD risk factors across
older age. METHODS: Participants (n = 4883) in the Cardiovascular Health Study free of prevalent CVD,
were stratified into three...
