Induction of Nitrate Reductase in Plant Shoots
A laboratory exercise that uses colormetric assay and corn seedling shoots to study the induction of enzyme activity by a substrate.
Small Regulatory RNAs May Sharpen Spatial Expression Patterns
The precise establishment of gene expression patterns is a crucial step in development. Formation of a sharp boundary between high and low spatial expression domains requires a genetic mechanism that exhibits sensitivity, yet is robust to fluctuations, a demand that may not be easily achieved by morphogens alone. Recently, it has been demonstrated that small RNAs (and, in particular, microRNAs) play many roles in embryonic development. Whereas some RNAs are essential for embryogenesis, others ar

Wireless Sensor Networks for Ecology
Field biologists and ecologists are starting to open new avenues of inquiry at greater spatial and temporal resolution, allowing them to "observe the unobservable" through the use of wireless sensor networks. Sensor networks facilitate the collection of diverse types of data (from temperature to imagery and sound) at frequent intervals -- even multiple times per second -- over large areas, allowing ecologists and field biologists to engage in intensive and expansive sampling and to unobtrusively
Sleeping Beauty Invades Rat's Genome
Knockouts are not just for Mice anymore. Aron Geurts and Howard Jacob from the Medical College of Wisconsin talk about their plans for creating transgenic rats using the Sleeping beauty transposon. Coming out of work pioneered by Colin Bishop's lab, Geurts and Jacob describe how the Sleeping Beauty system can be used to make transgenic rats and their plans to make the phenotype data from these rats available via the MCW PGA website (http://pga.mcw.edu) and the strains themselves accessible via a
What is a Profile?
Using TIG profiles as an entry point, this activity explores a broader theme of "profiling" to enable students to examine how they present themselves, as well as cultural perceptions and biases within themselves, their peers, and their community. Students will read TIG profiles and Member Stories, with the objective of better understanding others' perspectives to critically reflect and write about their own identity.
Not in Our Town Northern California: Staging a Response to Hate - Newark, CA
"Not In Our Town Northern California: When Hate Happens Here" looks at five communities that are dealing with hate violence. This Educator Guide addresses events that took place in Newark. Students from Memorial High School were planning a presentation of "The Laramie Project" for their fall play when they learned that one of their peers, a transgender student, had been murdered in a crime similar to the one they were exploring on stage. This Guide includes discussion ideas and activities relate

Kyoto Conference Outcome & Papers Presented
This website summarizes the outcomes and papers presented at the December 1995 Kyoto Conference. The Conference discussed Sustainable Contribution of Fisheries to Food Security. This page includes the Kyoto declaration and plan of action as well as executive summaries presented at the conference.
Living and non-living things
Living things often rely on non-living things to accomplish daily tasks. Living things have several characteristics that non-living things do not, such as the ability to move, eat, breathe, and reproduce. Living things and non-living things can interact even though they do not have the same characteristics.
Tissue movement in bipopulation tumour cord growth
Simulation of tumor cord growth where conversion of the tumor to glycolytic (anaerobic) metabolism takes place under hypoxia. This video shows volume fraction of glycolytic cell population and velocity of tissue movement. Isolines show hypoxia limits for aerobic and anaerobic cell lines respectively. This video reflects work in progress and may be different from the final results.
Economic History & History of Thought
The factories that changed the world, 1.) the mule-powered spinning mill (Britain in the 1820s), 2.) from the American system to the Ford system (1900s), and 3.) Toyota Production System (Lean manufacturing), are contrasted and the progression of production systems of the 19th and 20th centuries are arranged in order.

HUTCHINSON-GILFORD SYNDROME
Recent studies suggest that, as in other aging syndromes, the Hutchinson-Gilford syndrome is due to a defect in the mechanism of DNA repair. Mutations have been found in the Lamin A gene (LMNA) situated on chromosome 1.

Automotive Drum Brakes
Do you know when the first car was built? Do you know who built the first automobile? Would you guess, Henry Ford? Try again. Do you know by what means they used to stop that car? We know the brakes on the vehicles we drive today are quite different from those back in the 1800s. While knowing the history of the automobile is interesting, knowing how they work is also interesting. The automotive brake or to be more specific, the drum brake is what this instruction is designed to review. In this i
