Active Transport in Insect Malpighian Tubules
The Malpighian tubules of insects are an excellent model for examining the properties of secretion in a transporting epithelium. In this exercise students expose tubules from cockroaches or crickets to chlorophenol red and visually estimate the dye concentration in the lumen. By adding metabolic inhibitors and competitors or by substituting ion-free media they can demonstrate competition, specificity, and energy- or ion-dependence of active transport. Advanced students can design their own exper

D-Day to Berlin - The Battle for France (Part 4 of 6)
History Channel Video. 1944, Europe's future hung in the balance. Our 3-part series follows the story of Allied forces--from Normandy to the assault on Germany--and the victories that led to WWII's end in 1945.

By the end of August, Allied victory seemed assured. Rommel had been wounded, Hitler was directing the battle, and the German army w
