The sun sinks over the Rio Grande, the mountains around it glow orange, and the world slows down. The Mexican free-tailed bats inside the Jornada Cave are just starting to stretch and murmur. In this episode, we visit the nursery where all the baby bats stay together, and we accompany a new mother as she journeys into the sky with the rest of her crew for a night of hunting bugs via echolocation.

The Man Who Mastered Gravity is an intimate profile of Thomas Townsend Brown, a little-known scientist whose unorthodox ideas about electricity and gravity have made him the subject of decades of speculation and intrigue. Brown developed his novel concepts while serving in the U.S. Navy through the 1930s. In the first months of World War II he was abruptly discharged–despite his expertise in radio, radar, and mine sweeping.

Have you ever desired, deep within your soul, to make a comfortable full-time living from a farming enterprise? Too often people dare not even vocalize this desire because it seems absurd. It's like thinking the unthinkable. After all, the farm population is dwindling. It takes too much capital to start. The pay is too low. The working conditions are dusty, smelly and noisy: Not the place to raise a family. This is all true, and more, for most farmers.

J.E. Gordon strips engineering of its confusing technical terms, communicating its founding principles in accessible, witty prose.

Everyone who reads (or listens to), and enjoys that previous work, will benefit from this additional information.

In What It's Like to Be a Bird, David Sibley answers the most frequently asked questions about the birds we see most often. This special brand-new audio edition is geared as much to nonbirders as it is to the out-and-out obsessed, covering more than 200 species. While its focus is on familiar backyard birds—blue jays, nuthatches, chickadees—it also examines certain species that can be fairly easily observed, such as the seashore-dwelling Atlantic puffin.

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

A couple working six months per year for 50 hours per week on 20 acres can net $25,000 to $30,000 per year with an investment equivalent to the price of one new medium-sized tractor. Seldom has agriculture held out such a plum. In a day when mainline farm experts predict the continued demise of the family farm, the pastured poultry opportunity shines like a beacon in the night, guiding the way to a brighter future.

An Ojibwe elder once counseled Nerburn to "always teach by stories, because stories lodge deep in the heart.''
