Magmatic sulfides from Yerington, Nevada, and Yanacocha, Peru, were analyzed by laser ablation-inductively coupled mass spectrometry (LA-ICPMS) and electron microprobe to determine copper, gold, and silver concentrations and ratios in order to examine the relationship to the metal content of related magmatic-hydrothermal ores. The magmatic sulfides occur in plutonic rocks...

New antibiotic compounds with novel mechanisms of action have become essential in response to the recent paradigm of increasingly resistant strains of bacteria. Secondary metabolites (natural products) from bacteria such as Actinobacteria serve as lead compounds for the development of pharmaceutical drugs widely used to fight bacterial, viral and fungal...

Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
Feeding cows flaxseed rich in polyunsaturated fatty acids has been shown to decrease the proportion of saturated fatty acids and increase the proportion of n-3 polyunsaturated fatty acids (PUFAs) in milk. Consuming products enriched in n-3 PUFAs have beneficial effects to human health; thus, feeding cows flaxseed could potentially increase...

Gregory M. Benoit
The Grants Pass Batholith of Cretaceous age has intruded the
Triassic Applegate Group and metasedimentary rocks of the Jurassic
Galice Formation in the Murphy area of Josephine County, southwest
Oregon. The Applegate Group, mafic volcanic and sedimentary rock,
has been partially (nonequilibrium) metamorphosed under greenschist
facies conditions. The batholith, a...
