A laboratory exercise involving observing various plants and animals encountered and measuring physical factors that affect them as an approach to ecosystem analysis.
The Good and the Bad: Symbiotic Organisms from Selected Hosts
Symbiosis is defined as one organism living on, in, or with another organism. Three primary categories are mutualism (both organisms benefit), commensalism (commensal benefits and host not affected), and parasitism (parasite benefits and host harmed). Hands-on dissection of host animals provides examples ...
The Immune System: Red Cell Agglutination in Non-Humans
This exercise presents the concepts of immunology from biochemical, evolutionary, and adaptive standpoints. While all organisms have developed some mechanism of defense against external agents, vertebrates have the most complex immune responses capable of exquisite specificity and long duration. This affords a distinct advantage to species with a relatively long life span and low fecundity. This exercise explores the relationship between immunologic stimulation of the host with foreign antigens
The Power of Genetics: Using Classical and Molecular Genetics to Study "Real" Developmental Phenomen
The goal of this laboratory exercise is to provide a laboratory experience for undergraduates, in which they apply fundamental genetic principles to the study of a complex developmental process, specifically, root cell shape determination in the simple plant Arabidopsis thaliana. In this exercise, students identify putative root cell shape mutants, analyze an F2 segregating population, and finally use molecular techniques to determine where a specific mutation in located within the genome. This
The Study of Development Using Red Algae
This exercise can be used to demonstrate developmental processes at the cellular level, environmental control of photosynthesis, and cell enlargement by using red algae, which is well-suited for these types of experiments.
The Use of Lectins Agglutinins to Study Cell Surfaces
Using lectins, proteins which combine specifically with carbohydrate molecules or groups, this activity will introduce the students to the many important roles that the cell membrane serves in biological processes.
Water and Solute Movement Through Red Blood Cell Membranes
This resource is a detailed laboratory exercise suitable for undergraduate laboratory courses in biochemistry, physiology and cell biology. It includes detailed background information and student outlines, instructors notes, and suggested anaylses.
Remote Sensing Guides: Basic
The Remote Sensing guides are designed for people who want to learn how to benefit from remotely sensed imagery without having to learn the nitty-gritty details of how remote sensing works. All guides can be viewed online or downloaded in PDF format. The guides in the Basicset explain and illustrate fundamentalof remote sensing.
Wall Street Woes, Author Anouar Majid and Honoring Doris lessing
Could we see a repeat of the big stock market crash of '29? This week on Bill Moyers Journal, veteran market watcher Robert Kuttner and Wall Street insider William H. Donaldson give their read of the current economic landscape and discuss the risks of the deregulation of the financial industry. Donaldson was the 27th chairman of the SEC and is the former chairman and chief executive of the New York Stock Exchange, and Kuttner is co-founder and co-editor of The American Prospect magazine and wa
Ron Paul and Dennis Kucinich
Thousands of media outlets descended on Iowa, erecting a powerful wall of TV cameras and reporters between the voters and candidates. This week on Bill Moyers Journal in two interviews, Bill Moyers talks with Ron Paul and Dennis Kucinich, candidates with an inside view of the process who know well the power of the press to set expectations and transform the agenda. Also on the program, leading expert on media and elections Kathleen Hall Jamieson, director of the Annenberg Public Policy Center
David Cay Johnston, Craig Unger, Harvey J. Kaye
With all the talk of change coming out of the presidential campaigns, can we expect big money to lose its grip on Washington? Bill Moyers interviews NEW YORK TIMES investigative reporter and Pulitzer Prize-winner David Cay Johnston who says America's system has been rigged to benefit the super-rich. Also on the program, Bill Moyers talks with Harvey J. Kaye whose book Thomas Paine and the Promise of America channels the "the greatest radical of a radical age." Bill Moyers sits down with journal
Orchestrating cell separation in plants: What are the risks and benefits?
In this podcast, Professor Roberts from the School of Biosciences discusses his research into the mechanism responsible for regulating cell separation in plants. In particular how plants 'shed' parts of themselves such as leaves or fruit. Professor Roberts explores the potential application of his research, through prevention or encouraging of the 'shedding' process, agricultural harvests could potentially be increased or even synchronised.
Professor Roberts also discusses the resistance faced

Stem Cells: 5 Year Progress Report
Embryonic stem cells can transform themselves into every cell in your body. Does researching these stem cells violate human sanctity, or is it medicine's brightest frontier? What are the prospects for adult stem cells?
Paleobiology Database
The Paleobiology Database is a public resource for the scientific community. Its purpose is to provide global, collection-based occurrence and taxonomic data for marine and terrestrial animals and plants of any geological age, as well as web-based software for statistical analysis of the data.
