A Sea Biscuit's Life

submitted by: nelas
This video shows the life cycle of the sea biscuit Clypeaster subdepressus and is part of my master's thesis project at the Biosciences Institute of University of São Paulo. We collected adults from sand beds of São Sebastião Channel (São Sebastião, SP, Brazil) and induced gamete release (eggs and sperm). We did the fertilization in vitro and followed the embryonic development in the laboratory, under light microscopy. Embryos become swimming larvae, approximately 0.2 mm wide,...

The Effect of Universal Influenza Immunization on Mortality and Health Care Use

submitted by: jeff_kwong
Background In 2000, Ontario, Canada, initiated a universal influenza immunization program (UIIP) to provide free influenza vaccines for the entire population aged 6 mo or older. Influenza immunization increased more rapidly in younger age groups in Ontario compared to other Canadian provinces, which all maintained targeted immunization programs. We evaluated the effect of Ontario's UIIP on influenza-associated mortality, hospitalizations, emergency department (ED) use, and visits to...

Development Geology of the Antelope Shale: Section 1Y, Cymric Field, San Joaquin Valley, California - The Antelope Shale reservoir in Section 1Y, Cymric Field, San Joaquin Valley, California is one of Chevron’s key assets. The reservoir is a Miocene Age member of the Monterey Formation composed of Opal A (amorphous), Opal CT (cristobalite, tridimite) and Quartz phase diatomaceous deep water sediments. The Antelope Shale has an anomalously high average porosity of 58%, high initial oil...

Digital Archaeology in the Southern Levant

submitted by: charwang

In an effort to update and modernize the field of archaeology, site architectural plans, stratigraphic profiles, and ceramic plates will be digitalized and vectorized to be presented in a queryable online database. The creation of a queryable database, to replace print media, would allow for complex statistical and analytical computations between and within archaeological sites.

L-DOPA Is an Endogenous Ligand for OA1

submitted by: medtv
Albinism is a genetic defect characterized by a loss of pigmentation. The neurosensory retina, which is not pigmented, exhibits pathologic changes secondary to the loss of pigmentation in the retina pigment epithelium (RPE). How the loss of pigmentation in the RPE causes developmental defects in the adjacent neurosensory retina has not been determined, but offers a unique opportunity to investigate the interactions between these two important tissues. One of the genes that causes albinism...

Minimize Hypoglycemic Episodes Utilizing Remote Assistance via Mobile Phones

submitted by: syhon

My project involves researching on the versatile dynamics of hypoglycemia and how it can affect individuals differently. By doing so, I can identify specifications for an alarm device that can be tailored to each individual’s needs, so the device can warn the hypoglycemic individual before his or her glucose level falls below a certain threshold.
