The Brain Eater
In this scientific mystery, NOVA ventures to the front lines of medical research where scientists are scrambling to understand the strange new ailment popularly known as "mad cow disease." Highly infectious and incurable, this disease has claimed the lives of nearly a million cattle in Britain, and a variant is responsible for a handful of deaths in humans. Millions more people may have been exposed, and now the race is on to determine if we are on the brink of another deadly epidemic like AIDS or Ebola. What scientists are finding is making them rethink many fundamental assumptions about epidemiology and may hold startling implications for public health in the future.

Everest - The Death Zone
NOVA treks with a group of Himalayan climbers in their quest to reach the summit of Everest, along the way exploring in never-before-conducted tests how extremes of weather and altitude affect the human mind and body. Why do some people succumb so quickly to the ills caused by high altitude while others do not? Does exposure to extreme hypoxia—or lack of oxygen—take a lasting toll on the mind and body? Images of the brain scanned before and after the expedition may reveal truths about the physical traumas suffered in an oxygen-depleted environment, and give us new insight into why the tallest mountain in the world has claimed so many victims.

Warnings from the Ice
Could the world be facing the next deluge—a catastrophic rise in sea levels—as a result of the rapid break-up of the huge Antarctic ice sheets? The ice sheets hold 70% of the world's fresh water in a deep freeze cold enough to shatter steel, but now scientists are racing to understand whether the recent calving of a Connecticut sized iceberg signals the beginning of a giant meltdown.
s25e18 Crocodiles! 1998-04-29 01:00
Crocodiles!
An unprecedented look at a dangerous predator, this is the second of three natural history programs hosted by Sir David Attenborough. Surviving virtually unchanged since the days of the dinosaur and found throughout the world, these remarkable creatures have the tools for survival. Long known as vicious hunters, new photographic techniques now allow us to see them cooperating with each other and protecting their families. From tiny babies hatching from the shell we see them grow into great beasts capable of standing up to the lion and bringing down a zebra. BBC production in association with WGBH.
s25e19 The Truth About Impotence 1998-05-13 01:00
The Truth About Impotence
NOVA reports on new hope for victims of erectile dysfunction, also known as impotence. Among the promising therapies covered in the program are ones developed by Dr. Irwin Goldstein of Boston University School of Medicine and Dr. Harin Padma-Nathan, director of the Male Clinic in Santa Monica, CA. Actual cases are profiled, featuring men talking candidly about their problem—and going through treatment—on camera. Erectile dysfunction affects an estimated 52% of men between the ages of 40 and 70.
