The open ocean, far from the shore and miles above the seafloor, is a vast and formidable habitat that is home to the most abundant life on our planet, from giant squid and jellyfish to anglerfish with bioluminescent lures that draw prey into their toothy mouths. Into the Great Wide Ocean takes listeners inside the peculiar world of the seagoing scientists who are providing tantalizing new insights into how the animals of the open ocean solve the problems of their existence.

How is it that we can walk unfamiliar streets while maintaining a sense of direction? How can we come up with shortcuts on the fly, in places we've never traveled? The answer is the complex mental map in our brains. This feature of our cognition is easily taken for granted, but it's also critical to our species' evolutionary success. In From Here to There, Michael Bond tells stories of the lost and found - Polynesian sailors, orienteering champions, early aviators - and surveys the science of human navigation.

The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species-these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news.

Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.

All of life is profoundly shaped by the daily, monthly, and yearly cycles of our planet, and all creatures have internal timekeeping systems that rely on cues from the surrounding environment. With modern technology, we are changing our environments—and by proxy, the ecosystems around us—to override these innate rhythms of life. But at what cost? Life in Sync reveals how Earth’s rotations shape our biology, what human sleep cycles looked like before the advent of artificial light, and why technology can’t free us from the constraints of our circadian clocks.

In this epochal book, Immanuel Velikovsky, one of the great scientists of modern times, puts the complete histories of our Earth and of humanity on a new basis. He presents the results of his 10-year-long interdisciplinary research in an easily understandable, even entertaining manner. In spite - or even because - of the disgraceful hostility provoked by his theories, this book keeps being of ardent topicality, which in the light of recent scientific research is even growing.

In Deep is a podcast about water, climate and environment from The Water Main at American Public Media. In Season 1, we tackled the strangely fascinating yet troubling world of clean water -- from tap to toilet. Season 2 shines a light on environmental equity with a rich journalistic portrait of a working-class city and its residents at a perilous moment in our planet's existence.
