Who done It? Or what's that brown fuzzy stuff on my plum?
A safe and simple exercise that uses Koch's postulates to prove that an observed fungus is the cause of fruit disease. Since the fungus that causes brown rot of stone fruit is present naturally on the surface of these fruit, stone fruit purchased from the supermarket or farm stand will usually develop the disease. The fungi responsible for brown rot of stone fruit are not human pathogens. This lab requires dissecting and compound microscopes. A simplified exercise, without cultures, to demonstra

Observe an animation of a thunderstorm
These animated satellite images allow Earth science students to follow the formation of a thunderstorm over central Florida. The introduction explains how thunderstorms are formed by the updrafts of warm, moist air. Students are instructed to observe the animation to see the formation of cumulonimbus clouds and to observe the effect of downdrafts on the storms. The animation is linked to a map of the United States that shows the storm's location. Movie controls allow students to repeat, pause, o

Myasthenia Gravis - Motor Exam - Muscle Strength Sub-exam - Patient 11
Patient is a 52-year-old African American male who initially presented with diplopia and dysphagia about five years ago. Serologic testing demonstrated antibodies to the acetylcholine receptor, and repetitive nerve stimulation testing showed a decrement in CMAP at slow frequency repetitive stimulation. He now presents with generalized myasthenia, dysarthria, dysphagia and diplopia during a pyridostigmine-holiday for Tensilon testing.

Jim Vacarella Describes Avoiding the Draft During the Vietnam War
For young men like Jim Vacarella, the draft stood as the prime symbol of the war in Vietnam. Millions of young men tried to evade the draft: some fled to Canada; many feigned physical or mental illness, others used family connections to gain safe positions in the National Guard. For some, resisting the draft became an important way of protesting the war, and a few thousand men took public stands as draft resistors, burning their draft cards and challenging the government to imprison them.
