Detecting a Transposon Tag in Arabidopsis
Throughout the first half of the 20th century, geneticists assumed that a stable genome was a prerequisite for faithfully transmitting genes from one generation to the next. Working at Cold Spring Harbor Laboratory in the post-WWII era, Barbara McClintock found quite a different story in maize (corn). She observed numerous “dissociations” – broken and ring-shaped chromosomes – and traced the source of these mutations to the short arm of chromosome 9. There she identified two relate
Dynamic Gene is designed to let students learn about plant genomes by using bioinformatics to analyze newly sequenced genes in rice and maize. Many of these genes have only been predicted by computers and have never been closely examined by human beings! The site's name emphasizes the gene both as a dynamic structure that changes through evolutionary time, but also as a dynamic concept that changes with our increasing knowledge of genome organization. The design for Dynamic Gene recalls the "str

A plain language guide to copyright in the 21st century By Julien Hofman Computers and the Internet have transformed the way we produce and distribute information and entertainment. And copyright is struggling to keep pace with these changes. The authors of all kinds of works, from the humble email to blockbuster films, rely on copyright to protect what they produce. But authors and those who use their work are often unclear about what copyright allows and what it prohibits. This book was wri
Mapping Margery Kempe
Margery Kempe's spiritual biography is often called the first autobiography in English. A married woman who attempted to live a life devoted to Christ, Margery sought official Church recognition for her status as a spiritual woman and mystic, while continuing to live and travel in the secular world. She experienced intense emotional visionary encounters with Christ, which have at times a strikingly homely quality. Her Book, dictated by her to a scribe, records these visions as well as her travel

American Women's Dime Novel Project
Dime novels written by women were once enormously popular with their readers, but the genre has been neglected for most of its history by scholars, collectors, and libraries. The genre suffers from the double burden of being both popular and written for working-class women. This project hopes to overcome the history of oversight to both the form and its readers by providing information about the novels themselves, the authors, the readers, and nineteenth century public reaction. This site is a

This site invites you to explore the process of piecing together the lives of ordinary people in the past. It is an experimental, interactive case study based on the research that went into the book and film A Midwife’s Tale, both based upon the remarkable diary of 18th-century midwife/healer Martha Ballard. Although DoHistory is centered on the life of Martha Ballard, you can learn basic skills and techniques for interpreting fragments that survive from any period in history.
Stereotypes of the French
This unit comprises four major lessons which are distinct yet cumulative. In the first lesson, the students will lay the groundwork for their examination of French stereotypes by generating those stereotypes themselves. They may draw, write, or find examples of what they think are "typical" French things. In the second lesson, they will be required to change perspective -- instead of being the examiners, they will be the examined culture. Students will look at various examples of stereotypes of
