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 answers to the biggest cosmic puzzlers of our time. Somewhat. Each question is the focus of new experiments that are either underway or in the queue.
Hear the latest results in the search for gravitational waves that would be evidence for cosmic inflation, as well as the hunt for dark matter and dark energy. And because these questions are bigger than big, we’ve enlisted cosmologist Sean Carroll as our guide to what these experiments might reveal and what it all means.

“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 to say to the aliens was the focus of a recent conference in which participants shifted their attentions away from listening for extraterrestrial signals to transmitting some. In this show, we report on the “Communicating Across the Cosmos” conference held at the SETI Institute in December 2014.
Find out what scientists think we should say. Also, how archeology could help us craft messages to an unfamiliar culture. Plus, why journalists might be well-suited to writing the message. And, a response to Stephen Hawking’s warning that attempting to contact aliens is too dangerous.

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 prototype cellphones in Star Trek.
We take a look at science that seems inspired by filmic sci-fi, for example scientists manipulating memory as in Sunshine of the Spotless Mind. And despite his famous film meltdown, Charleton Heston hasn’t stopped the Soylent company from producing what it calls the food of the future.
Plus, why eco-disaster films have the science wrong, but not in the way you might think. And, what if our brains are simply wired to accept film as fact?

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 invented the blue LED.
Find out why this LED hue of blue was worthy of our most prestigious science prize … how some bacteria actually breathe rust … and a plan to cure disease by zapping our nervous system with electric pulses.

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 century – Ada Lovelace, a mathematician and Lord Byron’s daughter – said they would never surpass human ability. Was she right?
We consider the near-term future of computing as the Internet of Things is poised to link everything together, and biologists adopt the techniques of information science to program living cells.

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 in many animals and plants.
Evolution has evolved, and we take a look at some of the recent developments.
A biologist describes the escalating horn-to-horn and tusk-to-tusk arms race between animals, and a paleoanthropologist explains why the lineage from chimp to human is no longer thought to be a straight line but, instead, a bush. Also, New York Times science writer Carl Zimmer on the diversity of bacteria living on you, and which evolutionary concepts he finds the trickiest to explain to the public.

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 don’t know. Few of us do. Scientists say we’re spectacularly incompetent at recognizing our own incompetency, and that sometimes leads to trouble.
Find out why wrongness is the by-product of big brains and why even scientists – gasp! – are not immune. Plus, a peek into the trash bin of history: the biggest scientific blunders and the brighter-than-bright brains that made them. Including Einstein.
*Oh, and the Sun burns hydrogen to produce helium. But then, you knew that.

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 true outliers. Outliers also exist with natural events: hurricane Katrina, for example, or the asteroid that wiped out the dinosaurs. Such events are rare, but they often have outsized effects.
In this hour we imagine the unimaginable – including the unexpected events labeled “black swans” – and how we weigh the risk for any of them. Also, how a supervolcano explosion at Yellowstone National Park could obliterate the western U.S. but shouldn’t stop you from putting the park on your vacation itinerary.

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 brain, for example. So will humans always remain the boss of super-smart, swarming machines?
We discuss the biology of zombie ants and how to build robots that self-assemble and work together. Also, how to guarantee the moral behavior of future ‘bots.
And, do you crave cupcakes? Research suggests that gut bacteria control what we eat and how we feel.

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 non-existent from a biological perspective, and how the snippet of DNA that is the Y chromosome came to separate male from female.
Plus, why we’re wired to categorize. And, a groundbreaking court case proposes to erase the dividing line between species: lawyers argue to grant personhood status to our chimpanzee cousins.

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 land masses into one supercontinent – Pangaea, as it’s called – is a phenomenon that’s happened over and over during Earth’s history. And it will happen again. Meet our future supercontinent home, Amasia, and learn what it will look like.
Meanwhile, as California waits for the Big One, geologists discover that major earthquakes come in clusters. Also, our planet is not the only solar system body with tectonic activity. Icy Europa is a mover and shaker too.
And why is land in the western part of the U.S. literally rising up? Mystery solved!

You think your life is fast-paced, but have you ever seen a bacterium swim across your countertop? You’d be surprised how fast they can move.
Find out why modeling the swirl of hurricanes takes a roomful of mathematicians and supercomputers, and how galaxies can move away from us faster than the speed of light.
Also, what happens when we try to stop the dance of atoms, cooling things down to the rock bottom temperature known as absolute zero.
And why your watch doesn’t keep the same time when you’re in a jet as when you’re at the airport. It’s all due to the fact that motion is relative, says Al Einstein.

Who’s watching you? Could be anyone, really. Social media sites, webcams, CCTV cameras and smartphones have made keeping tabs on you as easy as tapping “refresh” on a tablet. And who knows what your cell phone records are telling the NSA?
Surveillance technology has privacy on the run, as we navigate between big data benefits and Big Brother intrusion.
Find out why wearing Google Glass could make everything you see the property of its creator, and which Orwellian technologies are with us today. But just how worried should we be? A cyber security expert weighs in.
Also, the benefits of an eye in the sky. A startup company claims that their suite of microsatellites will help protect Earth’s fragile environment.

Germs can make us sick, but we didn’t know about these puny pathogens prior to the end of the 19th century. Just the suggestion that a tiny bug could spread disease made eyes roll. Then came germ theory, sterilization, and antibiotics. It was a revolution in medicine. Now we’re on the cusp of another one. This time we may cure what ails us by replacing what ails us.
Bioengineers use advancements in stem cell therapy to grow red and white cells for human blood. Meanwhile, a breakthrough in 3D printing: scientists print blood vessels and say that human organs may be next.
Plus, implanting electronic grids to repair neural pathways. Future prosthetics wired to the brain may allow paralyzed limbs to move.
