Plant Viruses and Crops by Roger Beachy, April 2008 - Part 1: Cell and Molecular Biology of Plant Virus Infection: Early Events and Mechanisms of Pathogenesis

submitted by: video_collector

This seminar describes the cell and molecular biology of plant virus infection. The first lecture will discuss how virus replication centers are set up in plants and how viruses use host cell mechanisms to facilitate cell to cell movement and eventual pathogenesis.

Successful Aging: The Buzz on Successful Aging

submitted by: sjanderson

What does it mean to age successfully? After all, aren’t we accomplishing this just by being alive? The term "successful aging" is vague and leaves much to the imagination. Yet, there is a growing interest in this topic. UCSD’s Stein Institute for Research on Aging has embarked on its own research project to discover the secrets to success. This presentation provides insights related to successful aging and discuss current research findings and proposed models.

How to Use Portable Steam Collector

submitted by: drscottkelley

This video shows a demonstration of how to use a custom made steam collector designed to condense steam from geothermal vents (aka., fumaroles). This device was used used to collect samples of halophilic Archaea from fumaroles around the world, work which was published in:

Ellis, D., R.W. Bizzoco, and S.T. Kelley. (2008) Halophilic Archaea identified in fumarole steam vapor from vents around the world. Environmental Microbiology, 10: 1582-1590.

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,...

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...
