PopG Genetic Simulation Program version 4.01 October, 2013 This is a one-locus, two-allele genetic simulation program for use by students. It simulates multiple populations and allows you to see the effect of natural selection, mutation, migration, and genetic drift. It is freely downloadable. It is written in Java, and will run on Windows, Mac OS X, and Linux systems if they have Java installed on them. At its web site evolution.gs.washington.edu/popgen/ is a downloadable "zip archive" which contains a Java archive file which has the Java executable as well as the Java source code. The Java source for popg is called PopGUserInterface.java and is in the folder src. Getting PopG You can fetch PopG using the links below. We have posted a Zip archive of PopG, including Java archives and documentation files. Fetch it here. Installing PopG Here are instructions for saving, unpacking, and installing PopG from different browsers, and on operating systems. Using Chrome on Windows, Mac OS X, or Linux Click on the link.

Inside Search Google is the most popular search engine on the web. Most of us rely on Google search for finding information. Sometimes it can be difficult to find just the right information we are actually looking for out of the hundreds or thousands of results returned in Google’s search. Despite using Google every day, we still use it in its simplest form. Towards this end, in July 2012 Google created an online course called Power Searching with Google. The Google Power Searching course is available online on edX as an Xseries program. Go to Power Searching with Google Course The course is structured as a series of 6 modules, each of which comprises of 5-6 short video lessons. The instructor of the course is Daniel M. This Power Searching course introduces participants to the idea of search, how Google works, and gives them the methods, strategies and tactics to find what they need to find.

Stellarium Genetic Education Resources for Teachers Genetic Education Resources for Teachers As genetics and genomics research advances rapidly through the knowledge gained from the completed human DNA sequence, teachers and educators require new classroom tools to present the rich history, complexity and excitement of the world of genetics and genomics.These teaching resources include specific teaching plans to present the history, facts and genetic terminology behind the Human Genome Project. Teaching Resources Internet-Based Tools for Teaching the Microbiome Websites, articles, research studies and more to help teach about the microbiome.

Discovery Education | Siemens Science Day Hands-on Activities for Teaching Biology to High School or Middle School Students by Drs. Ingrid Waldron and Jennifer Doherty, University of Pennsylvania The expression "hands-on, minds-on" summarizes the philosophy we have incorporated in these activities -- namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts. For example, it is helpful to use hands-on models to engage student interest and foster multiple modality learning, but it is crucial to closely link the modeling activity to student understanding of the actual biological processes. Additional resources for teaching biology are available at Introduction to Biology Is Yeast Alive? Students evaluate whether the little brown grains of yeast obtained from the grocery store are alive by testing for metabolism and growth.

Beyond Penguins and Polar Bears Rediscovering Biology - Online Textbook: Unit 8 Cell Biology & Cancer "We now understand a lot about cancer. We know that it results from a series of genetic changes having to do with cell division and growth control and genetic instability, mortality, the suicide mechanism in cells; the ability of the cells to migrate; the ability of the cells to attract to them a blood supply. And so that's pretty profound that in a few sentences one can summarize a sophisticated, fundamental understanding of what a cancer is." -- Leland Hartwell Introduction A multicellular organism can thrive only when all its cells function in accordance with the rules that govern cell growth and reproduction. To understand how and why cells rebel, we need to understand the normal functions of cell growth and reproduction. Although cancer comprises at least 100 different diseases, all cancer cells share one important characteristic: they are abnormal cells in which the processes regulating normal cell division are disrupted.

Search, Collect, and Share | SMILE Susan Benton Strange Facts In 1903 Edouard Benedictus knocked a glass bottle of chemicals off a shelf. To his surprise, the bottle cracked all over but did not shatter into tiny pieces and scatter across the floor. Something seemed to be holding the broken pieces together. The bottle contained cellulose nitrate, which had coated the inside. Today’s “safety glass” is made by a different method, but the idea is the same. Click on the video link below in the LEARN MORE box, go to the two minute mark, and find out why the timing of this discovery was important.
