Zooarchaeological Analysis of Avian Skeletal material in Neolithic and Early Bronze Age Mortuary Contexts, Cis-Baikal, Siberia
DownloadSpring 2013
During the Neolithic and Early Bronze Age in Cis-Baikal, Siberia, human groups inhabiting the region interred their deceased with a variety of objects, including modified and unmodified avian skeletal elements. Archaeological excavation of graves in the Shamanka II, Lokomotiv, and Ust’-Ida...

Zinc in Precambrian iron formations: The record, partitioning, diagenetic effects and implications for eukaryotic metallome evolution
DownloadFall 2013
Zinc is amongst the most important trace elements for eukaryotes. Previous work has suggested it to have been at biolimiting concentrations for much of the Precambrian, thereby limiting eukaryotic evolution. Yet, the iron formation (IF) record, a critical proxy for paleomarine conditions, has...

Electrochromism is the phenomenon where the optical transmittance or absorbance of a material changes under an applied electric potential. When a voltage is applied to an electrochromic material, the optical properties of the material are altered in a reversible fashion. Owing to their optical...

Acting as a co-factor for hundreds of enzymes, zinc (Zn) is an essential trace metal required for organismal success across all phyla. When aquatic organisms such as fish are Zn deficient, growth, metabolism, and health are all negatively impacted. However, Zn in excess may also impair overall...

Zic transcription factors regulate retinoic acid metabolism during zebrafish neural development
DownloadSpring 2012
Retinoic acid (RA) has a crucial role in embryonic nervous system development - controlling anterior-posterior patterning, neural differentiation, and cell proliferation. During zebrafish embryogenesis, levels of RA are tightly regulated by the combinatorial action of synthesis and degradation...
