Bioinformatics and Computational Biology Solutions Using R and Bioconductor
Covers the basics of R software and the key capabilities of the Bioconductor project (a widely used open source and open development software project for the analysis and comprehension of data arising from high-throughput experimentation in genomics and molecular biology and rooted in the open source statistical computing environment R), including importation and preprocessing of high-throughput data from microarrays and other platforms. Also introduces statistical concepts and tools necessary t
Problem Solving for Immunization Programs
Countries around the world - even those at war - are collaborating to ensure that children under the age of five don't die from diseases for which vaccines are available. In the past twenty years, global vaccine coverage has surpassed eighty percent, and a second disease, polio, is nearly eradicated. In the United States, coverage rates are even higher, and vaccine-preventable diseases are now rare. Never have so many resources been focused on immunization - yet problems remain. Additional, high
Analog Integrated Circuit Design
An introductory course in analog circuit synthesis for microelectronic designers. Topics include: Review of analog design basics; linear and non-linear analog building blocks: harmonic oscillators, (static and dynamic) translinear circuits, wideband amplifiers, filters; physical layout for robust analog circuits; design of voltage sources ranging from simple voltage dividers to high-performance bandgaps, and current source implementations from a single resistor to high-quality references based o
Basics of the Coordinate Plane
This selection provides an introduction to the basics of the coordinate plane. An interactive board is used to show the x and y axis, quadrants, and an ordered pair. A tip is also provided to help students learn the number of each quadrant. ( 1:46)
Kemp's Ridley Turtle Hatchlings Emerging From Nest
This short video gives excellent real life footage of baby Ridley Turtles hatching and emerging from their nest in the sand. Kemp’s ridley turtle is the most severely endangered marine turtle in the world; in the 1980s only a few hundred females were observed nesting, although the population is now showing signs of recovery. It is also one of the smallest turtles, with adults weighing less than 45 kilograms. This is a great resource to help build background knowledge and to help make

Ocean Explorer: 2002 Explorations
The National Oceanic and Atmospheric Administration's (NOAA) Ocean Explorer Web site (last mentioned in the March 8, 2002 -NSDL Scout Report for the Life Sciences_ ) has begun several of this seasons explorations. Six new voyages have been, or soon will be undertaken and the Web pages include daily updates, photos, and videos of the research efforts. Studies include biological monitoring of marine sanctuaries, hydrothermal vents, geological studies, and recovery of a sunken Civil War ship. An in

Genetic Status of Atlantic Salmon in Maine
This interim report from the National Research Council's (NRC) Committee on Atlantic Salmon in Maine is a prepublication of the March 2002 report provided by National Academy Press. The once abundant populations of Atlantic Salmon in Maine have declined in recent years, now listed as endangered. The NRC Committee believes that "understanding the genetic makeup of Maine's salmon is important for recovery efforts." This 48-page report includes information on the salmon's biology, evolution, geneti
Earth Science Australia

Forces, Forces Everywhere
Students are introduced to Newton’s laws of motion. They learn about forces associated with motion, gravitational acceleration, weight, normal force, static and kinetic friction, drag, and free-body diagrams. These concepts are reinforced with the associated activity, Dragged Racers, to analyze frictional forces as they use their mousetrap-powered model cars to relate displacement, velocity and acceleration with external forces acting upon them.
