Mosses (Phylum Bryophyta) are widely considered to be among the most ancient groups of land plants (embryophytes) and they are the second most speciose embryophyte phylum with ~13,000 extant species. Despite their diversity and antiquity, mosses have a limited fossil record, which primarily consists of gametophytes entombed in Cenozoic amber....
The eruptive history of the Quaternary Cascades arc has been relatively well characterized. However, much less is known about the frequency and sizes of explosive eruptions produced by earlier stages of the arc. The Late Neogene Deschutes Formation of Central Oregon preserves a remarkable record of heightened pyroclastic activity during...
The advent of improved DNA sequencing technologies has allowed the analysis of various microbial communities. Bloom-forming freshwater cyanobacteria can produce toxins and taste-and-odor compounds that can negatively affect drinking water supplies. Here, I have employed second- and third-generation sequencing technologies to characterize bloom-forming freshwater cyanobacterial genomes and their associated heterotrophic...
Hibiscus and lilacs (Syringa spp.) are economically important nursery crops in the US that accounted for 4.5 million units ($30 million) and 2 million units ($20 million), respectively (USDA, 2016). To maintain and expand the market share of ornamental plants such as lilacs and Hibiscus, novel performance, floral ornamental value,...
Uveitis is a serious ophthalmological disorder characterized by intraocular infiltration of inflammatory cells. In most cases, uveitis is derived from the adaptive immune response. More specifically, CD4+ T lymphocytes play an important role in the pathogenesis of uveitis by recognizing uveitogenic antigen and orchestrating the immune response. While it is...
We introduce a novel ambient hydrolysis deposition (AHD) methodology that, for the first time, employs sequential water adsorption followed by a hydrolysis reaction to infiltrate tiny SnO2₂ particles inside nanopores of mesoporous carbon in a conformal and controllable manner. The empty space in the SnO2₂/C composites can be adjusted by...
A method was developed for the measurement of 19 parent PAHs (PAHs) and 34 hydroxylated
PAHs (OH-PAHs) in urine and personal air samples of particulate matter less than 2.5 um in
diameter (PM[subscript 2.5]) using GC-MS and validated using NIST SRM 3672 (Organic Contaminants in
Smoker’s Urine) and SRM 3673...

Cyanophage are viruses that infect cyanobacteria, photosynthetic microorganisms which are known to produce several anticancer and antibacterial chemical compounds. Cyanophage are significant members of microbial communities in marine and freshwater environments. There has been significant difficulty inventorying marine and freshwater cyanophage, however, due to the difficulty in cultivating their hosts....

More needs to be done by the private sector to optimize the drug discovery and development pipeline. In addition, significant efforts should also be focused on the understanding of mechanism of diseases, on the characterization of unexplored biochemical pathways and on the validation of new protein targets. Chemical genomics, which...
In 2008, China released a new green initiative, the Green Securities Policy, to increase the sustainability of Chinese capital markets. One of the integral components of the policy is the new environmental disclosure regulation which prescribes Chinese listed companies in the 14 highly polluting industries to report required environmental information....
