What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

Today's "machine-learning" systems, trained by data, are so effective that we've invited them to see and hear for us - and to make decisions on our behalf. But alarm bells are ringing. Systems cull résumés until, years later, we discover that they have inherent gender biases. Algorithms decide bail and parole - and appear to assess black and white defendants differently. We can no longer assume that our mortgage application, or even our medical tests, will be seen by human eyes. And autonomous vehicles on our streets can injure or kill.

99% Invisible is a big-ideas podcast about small-seeming things, revealing stories baked into the buildings we inhabit, the streets we drive, and the sidewalks we traverse. The show celebrates design and architecture in all of its functional glory and accidental absurdity, with intriguing tales of both designers and the people impacted by their designs.

What won't we try in our quest for perfect health, beauty, and the fountain of youth? Well, just imagine a time when doctors prescribed morphine for crying infants. When liquefied gold was touted as immortality in a glass. And when strychnine - yes, that strychnine, the one used in rat poison - was dosed like Viagra. Looking back with fascination, horror, and not a little dash of dark, knowing humor, Quackery recounts the lively, at times unbelievable, history of medical misfires and malpractices. 

For any task you might want to do, there's a right way, a wrong way, and a way so monumentally complex, excessive, and inadvisable that no one would ever try it. How To is a guide to the third kind of approach. It's full of highly impractical advice for everything from landing a plane to digging a hole.

In Venomous, molecular biologist Christie Wilcox investigates venoms and the animals that use them, revealing how they work, what they do to the human body, and how they can revolutionize biochemistry and medicine today. Wilcox takes us from the coast of Indonesia to the rainforests of Peru in search of the secrets of these mysterious animals.

In The End Is Always Near, Dan Carlin looks at questions and historical events that force us to consider what sounds like fantasy; that we might suffer the same fate that all previous eras did. Will our world ever become a ruin for future archaeologists to dig up and explore? The questions themselves are both philosophical and like something out of The Twilight Zone.

At 14, Amber could boast of killing her guinea pig, threatening to burn down her home, and seducing men in exchange for gifts. She used the tools she had available to get what she wanted, and she didn't care about the damage she inflicted. A few miles away, Lenny Skutnik was so concerned about the life of a drowning woman that he jumped into the ice-cold river to save her. How could Amber care so little about others' lives, while Lenny cared so much? 

From finding a spouse to finding a parking spot, from organizing one's inbox to understanding the workings of human memory, Algorithms to Live By transforms the wisdom of computer science into strategies for human living.

Have you ever seen something that wasn't really there? Heard someone call your name in an empty house? Sensed someone following you and turned around to find nothing? Hallucinations don't belong wholly to the insane. Much more commonly, they are linked to sensory deprivation, intoxication, illness, or injury. People with migraines may see shimmering arcs of light or tiny, Lilliputian figures of animals and people.

Interweaving a grand historical narrative with cutting-edge climate science and genetic discoveries, Kyle Harper traces how the fate of Rome was decided not just by emperors, soldiers, and barbarians but also by volcanic eruptions, solar cycles, climate instability, and devastating viruses and bacteria. He takes listeners from Rome's pinnacle in the second century, when the empire seemed an invincible superpower, to its unraveling by the seventh century, when Rome was politically fragmented and materially depleted.

A globally renowned materials scientist, Miodownik has spent his life exploring objects as ordinary as an envelope and as unexpected as concrete cloth, uncovering the fascinating secrets that hold together our physical world.

The Late Middle Ages-the two centuries from c. 1300 to c. 1500 - might seem like a distant era, but students of history are still trying to reach a consensus about how it should be interpreted. Was it an era of calamity or rebirth? Was it still clearly medieval or the period in which humanity took its first decisive steps into modernity? These 24 provocative lectures introduce you to the age's major events, personalities, and developments, and arms you with the essentials you need to form your own ideas about this age of extremes.

A spirited narrative on the fascinating art and science of alcohol, sure to inspire cocktail party chats on making booze, tasting it, and its effects on our bodies and brains. Drinking gets a lot more interesting when you know what's actually inside your glass of microbrewed ale, single-malt whisky, or Napa Cabernet Sauvignon. All of them begin with fermentation, where a fungus called yeast binges on sugar molecules and poops out ethanol. Humans have been drinking the results for 10,000 years. Distillation is a 2,000-year-old technology - invented by a woman - that we're still perfecting today.

Yuval Noah Harari, author of the critically acclaimed New York Times best seller and international phenomenon Sapiens, returns with an equally original, compelling, and provocative book, turning his focus toward humanity's future and our quest to upgrade humans into gods.
