Apparency and Actuality

submitted by: hsrikm
Apparency and actuality are discussed with respect to science, genetics, evolution, cognition and perception. Rules for a (sub)set of actual/allowable sets of entities and objects from a total set that is based on differences and contrasts extracted from perceptual experience of the world elucidate tenable combinations/recombinations from a total of the transparent(history/past dependant) and the apparent as they can be construed to comprise the actual/real faces of perception. The elements...

Membrane Rafts by Satyajit 'Jitu' Mayor, May 2007 - Part 1: Historical Perspective: What are Membrane Rafts? (38:19)

submitted by: video_collector
The plasma membrane demarcates the inside of the living cell from the outside, serving both as the ultimate physical barrier and location where the cell transacts its business with the outside world. The study of the structure of cell membranes continues to be fertile ground for research for many biologists today; the idea of "Membrane Rafts" has only heightened interest in this area. The main focus of this three part series is to explore the concept of "Membrane Rafts". In the first part,...

The Origin of Vertebrates - Part 1: The Origin of the Vertebrate Nervous System: The Hemichordat

submitted by: video_collector
Modern cell and developmental biology has a lot to contribute to our understanding of the deep history of animal origins, which until recently has been largely the province of paleontology. In this set of lectures, I hope to show how recent studies by a very small group of scientists on a virtually unknown phylum of marine organisms, the hemichordates, has helped explain some of the major mysteries of the origin of vertebrates. This is a tour of not only vertebrate origins but the...

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.
