1 + 1: A Natural History of Sexuality
Biological evolution has resolutely chosen to hand down genetic information through the fragile and uncertain process of sexual reproduction—employed by approximately 95 percent of the Earth’s species—rather than through the simpler and surer method of asexual reproduction.
The populations of many countries are aging.
AIDS: The Women Speak
The AIDS epidemic is affecting more and more women—women who are HIV-positive, women who live with HIV-positive partners and children, and women who are caring for AIDS patients.
Allan Wilson: Evolutionary
Allan Wilson, a groundbreaking researcher and a lightning rod for controversy, revolutionized science and galvanized the scientific community through his quantitative biochemical approach to the history of evolution. Drawing upon the insights and recollections of those who knew Wilson best, this program—narrated by paleoanthropologist Tim White, codiscoverer of the hominid “Lucy”—correlates milestones of his remarkable career with his enduring contributions that range from molecular phylogenies of multiple species to an understanding of mechanisms underlying the mode and tempo of organismal evolution. Commentary by David Wake, professor emeritus of zoology at the University of California, Berkeley, and many others is featured.

Aspects of MS
While the cause of multiple sclerosis remains unknown, knowledge of how MS attacks the body is improving.
The microexplorers discover that gardens support an amazing community of small life including herbivorous and predatory insects, pollinating insects, and giant earthworms.
Biology Classics: Paramecium, Hydra, Planaria, and Daphnia, The
Understanding the amazing phenomena of life requires an intimate acuaintance with living things. This program introduces students to four organisms we call the Biology Classics, "classics" not only because they are featured in science textbooks, but because studying them broadens our concept of what it means to be alive.
Biology of Cnidarians, The
"Cnidarians" begins with a remarkable series of observations on Hydra including: habitat, structure, feeding, nematocyst discharge, locomotion (by looping), and its sexual and asexual reproductive strategies.
Biology of Plants, The
Clear graphic animation is used to describe the molecular level mechanisms of photosynthesis.
Biology of Seashores, The
Introduction to the study of seashoresAbiotic and Biotic Factors: Tides, wave shock, desiccation, and food sources.

Bladder Disorder: Interstitial Cystitis
Often mistaken for less debilitating problems, interstitial cystitis is a serious and painful disease of the bladder lining that, if not properly treated, can ruin a patient’s life.
Supreme machine, the brain is an organ whose complexity is beyond all understanding.
