Keeping Cool at Deep-Sea Vents
This Astrobiology Magazine article reports that a research team of marine scientists has determined that water chemistry controls the location and distribution of two species of weird worms inhabiting deep-sea hydrothermal vent sites: the tubeworm (Riftia pachyptila) and Pompeii worm (Alvinella pompejana). The article includes color images of the worms and monitoring equipment, links to related web pages and other astrobiology resources, and an MP3 machine text-to-speech function.

2.14 Summing up
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.

5.1 The essays in context
Childcare, education, working conditions, healthcare, crime … these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.

Exercise Physiology: The Response of Metabolic Rate to Physical Activity
In this lab, students measure their heart rate, oxygen consumption, and carbon dioxide production in various physical activities on a treadmill or cycle ergometer. After learning the techniques in the first lab period, each group of 3-4 students designs an independent investigation that is performed during the second lab period. To measure metabolic rate, students collect expired air in a Douglas bag, then measure the volume, the temperature, and the concentration of oxygen and carbon dioxide. W
