Thermography allows the investigator to create a 3 dimensional image based on infrared emissions from tissue. Warmer tissues show up as yellow and white, whereas darker colors represent cooler structures. Malignant tumors are metabolically active and appear yellow and white on the images.

Lines of Force
"Lines of Force" opens with footage of a dramatic explosion. For most of the piece, the screen is divided, into a triptych at first, and slowly into horizontal and vertical bars. Electronically manipulated footage shows a man walking, a marching band, ferns, cartoons, a window, and a train arriving on a set of tracks. The naturally occurring lines in the array of images presented mirror the electronically created bars and lines that divide the screen. Natural scenes provide a respite from the fr
Microbe Lab (MWV13)
MicrobeWorld visits the Marian Koshland Science Museum for "Microbe Lab,” a free day of activities for the general public. In this episode we interview Erika Shugart, deputy director of the Koshland Museum, about "Microbe Lab” and the Crack Koshie’s Curious Case: A Disease Detective Mission activity.

The relevance of role playing in environmental education.
This article published by the Commission on Biology Education summarizes a study of the relevance of role-playing in environmental education. The researchers created different role-plays and analyzed them in light of certain values that 8 to 10 year-old children were able to distinguish. They determined that role-plays do have an impact and they facilitate the emergence of values such as solicitude, aestheticism, solidarity, tolerance, responsibility and autonomy.
Scientist Uses Tombstones to Track Environmental Changes
This National Geographic News article discusses how a scientist uses tombstones to track environmental changes. Geomorphologist Tom Meierding visited more than 700 cemeteries and measured 15,000 tombstones to see what kind of environmental changes they might reveal.
