Take a look at how our genes influence the aging process. Professor Polk explores several theories for why we age and eventually die, then delves into the genetic mechanisms involved in aging. Find out how replication damages cells and why there is a limit to the number of healthy replications our cells can make.

For the 19th century, the world beneath the sea played much the same role that outer space played for the 20th. The ocean depths were both the ultimate scientific frontier and the home of imagination and the fantastic...Twenty years in the making and based on images of 19th century painters, photographers and scientific illustrators, Proteus brings these undersea worlds to life in a wonderfully unique film...The central figure of PROTEUS is biologist...

See what scientific research shows about our evolving emotional landscape, and why older people tend to be happier than the young. Depression can still be a problem for older adults, though—consider the most common causes, discover how symptoms may differ from those of younger people, and learn to match the treatment to the situation.

This film explores both the heartbreak and the glory of trying to unravel the secrets of outer space. Mark Devlin, PhD (the filmmaker’s brother) launches revolutionary telescopes on NASA high-altitude balloons. Dangerous, but necessary if he wants to look back in time and reveal a hidden Universe of never-before-seen galaxies. ..BLAST! follows Mark and his team on their grueling journey across 5 continents, from Arctic Sweden to Antarctica, as they...

Algae have sustained life on this planet since they were first modified by the atmosphere with photosynthetic by-products over two and a half billion years ago. From the microscopic to giant seaweeds, over 30,000 different forms exist today. In this program researchers discover how algae can transform, from life supporting to life threatening. Learn how we've depended on algae in the past and see the new ways we are putting them to use in cancer research,...

Michael and James explore how the chemicals in our food feed and build our bodies. The world is full of different cuisines and thousands of different meals. Yet when they’re reduced to their essence, there are actually just a handful of ingredients that our bodies absolutely need from our food to survive.. These essential molecules come in a series of familiar sounding groups – carbohydrates, fat, protein, vitamins and minerals – but Michael...

"Nonpareil science writer David Quammen explains how recent discoveries in molecular biology can change our understanding of evolution and life's history, with powerful implications for human health and even our own human nature." -- Publisher annotation.

"The Last Days of the Dinosaurs by Riley Black tells the story of the extinction of these prehistoric creatures and the beginning of our world ..."-- "Picture yourself in the Cretaceous period. It's a sunny afternoon in the Hell Creek of ancient Montana 66 million years ago. A Triceratops horridus ambles along the edge of the forest. In a matter of hours, everything here will be wiped away. Lush verdure will be replaced with fire. Tyrannosaurus rex...

Joy and Mark travel to Borneo to explore the reproduction challenges of our close cousin — the orangutan. The largest tree dwellers on the planet, orangutans mate, give birth and raise their young high in the jungle canopy. At an orangutan sanctuary in the rainforest, Mark and Joy come face-to-face with a super-male and uncover the latest scientific theories about how these kings exert their power over other males and seduce females in their territory....
