Are We Alone weaves together a universe of big ideas – from robots to memory to antimatter to dinosaurs. Tune in and make contact with science. We broadcast and podcast every week. radio.seti.org

herlock Holmes doesn't have a science degree, yet he thinks rationally - like a scientist. You can too! Learn the secrets of being irritatingly logical from the most famous sleuth on Baker Street. Plus, discover why animal trackers 100,000 years ago may have been the first scientists, and what we can learn from about deductive reasoning from today's African trackers. Also, the author of a book on teaching physics to your dog provides tips for unleashing your inner scientist, even if you hated science in school. And newly-minted scientists imagine classes they wish were available to them as grad students, …

Digging Our Past Feb. 2, 2015
ENCORE What's past is prologue. For centuries, researchers have studied buried evidence - bones, teeth, or artifacts - to learn about murky human history, or even to investigate vanished species. But today's hi-tech...
ENCORE Shh …mummy's the word! We don't want to provoke the curse of King Tut. Except that there are many curses associated with this fossilized pharaoh - from evil spirits to alien malevolence. So it's hard to know...
Here are questions that give a cosmologist - and maybe even you - insomnia: What happened after the Big Bang? What is dark matter? Will dark energy tear the universe apart? Let us help you catch those zzzzs. We're going to provide...
How to Talk to Aliens Jan. 12, 2015
"Dear E.T. …" So far, so good. But now what? Writing is never easy, but what if your task was to craft a message to aliens living elsewhere in the universe, and your prose would represent all humankind? Got writer's block yet? What...
Meet Your Replacements Jan. 5, 2015
ENCORE There's no one like you. At least, not yet. But in some visions of the future, androids can do just about everything, computers will hook directly into your brain, and genetic human-hybrids with exotic traits will be walking the streets....
ENCORE The sweet stuff is getting sour press. Some researchers say sugar is toxic. A new study seems to support that idea: mice fed the human equivalent of an extra three sodas a day become infertile or die. But should cupcakes be regulated like...
Science Fiction True Dec. 22, 2014
Don't believe everything you see on TV or the movies. Science fiction is just a guide to how our future might unfold. It can be misleading, as anyone who yearns for a flying car can tell you. And yet, sometimes fantasy becomes fact. Think of the...
Shocking Ideas Dec. 15, 2014
Electricity is so 19th century. Most of the uses for it were established by the 1920s. So there's nothing innovative left to do, right? That's not the opinion of the Nobel committee that awarded its 2014 physics prize to scientists who...
Living Computers Dec. 8, 2014
It's the most dramatic technical development of recent times: Teams of people working for decades to produce a slow-motion revolution we call computing. As these devices become increasingly powerful, we recall that a pioneer from the nineteenth...
Long Live Longevity Dec. 1, 2014
Here's to a long life - which, on average, is longer today than it was a century ago. How much farther can we extend that ultimate finish line? Scientists are in hot pursuit of the secret to longer life. The latest in aging studies and...
This Land Is Island Nov. 24, 2014
There are many kinds of islands. There's your iconic sandy speck of land topped with a palm tree, but there's also our home planet - an island in the vast seas of space. You might think of yourself as a biological island …...
Surfeit of the Vitalest Nov. 17, 2014
In the century and a half since Charles Darwin wrote his seminal On the Origin of the Species, our understanding of evolution has changed quite a bit. For one, we have not only identified the inheritance molecule DNA, but have determined its sequence...
Nuclear fission powers the Sun. Or is it fusion? At any rate, helium is burned in the process, of that you are certain. After all, you read that article on astronomy last week*. You know what you know. But you probably don't know what you...
Sounds Abound Nov. 3, 2014
The world is a noisy place. But now we have a better idea what the fuss is about. Not only can we record sound, but our computers allow us to analyze it. Bird sonograms reveal that our feathery friends give each other nicknames and share details...
We love our family and friends, but sometimes their ideas about how the world works seem a little wacky. We asked BiPiSci listeners to share examples of what they can't believe their loved-ones believe, no matter how much they hear rational...
Tale of the Distribution Oct. 20, 2014
We all have at least some musical talent. But very few of us can play the piano like Vladimir Horowitz. His talent was rarefied, and at the tail end of the bell curve of musical ability - that tiny sliver of the distribution where you find the...
Who's Controlling Whom? Oct. 13, 2014
A single ant isn't very brainy. But a group of ants can do remarkable things. Biological swarm behavior is one model for the next generation of tiny robots. Of course, biology can get hijacked: a fungus can seize control of an ant's...
What's the Difference? Oct. 6, 2014
We make split second decisions about others – someone is male or female, black or white, us or them. But sometimes the degrees of separation are incredibly few. A mere handful of genes determine skin color, for example. Find out why race is almost...
Land on the Run Sept. 29, 2014
Hang on to your globe. One day it’ll be a collector’s item. The arrangement of continents you see today is not what it once was, nor what it will be tomorrow. Thank plate tectonics. Now evidence suggests that the crowding together of all major...
