ENCORE The machines are coming! Meet the prototypes of your future robot buddies and discover how you may come to love a hunk of hardware. From telerobots that are your mechanical avatars … to automated systems for the disabled … and artificial hands that can diffuse bombs.
Plus, the ethics of advanced robotics: should life-or-death decisions be automated?
And, a biologist uses robo-fish to understand evolution.

Is space the place for you? With a hefty amount of moolah, a trip there and back can be all yours. But when the price comes down, traffic into space may make the L.A. freeway look like a back-country lane.
Space is more accessible than it once was, from the development of private commercial flights … to a radical new telescope that makes everyone an astronomer … to mining asteroids for their metals and water to keep humanity humming for a long time.
Plus, move over Russia and America: Why the next words you hear from space may be in Mandarin.

ENCORE It’s one of the biggest questions you can ask: has the universe existed forever? The Big Bang is supposedly the moment it all began. But now scientists wonder if there isn’t an earlier chapter to our origin story. And maybe chapters before that! What happened before the Big Bang? It’s the ultimate prequel.
Plus – the Big Bang as scientific story: nail biter or snoozer?

What’s for dinner? Meat, acorns, tubers, and fruit. Followers of the Paleo diet say we should eat what our ancestors ate 10,000 years ago, when our genes were perfectly in synch with the environment.
We investigate the reasoning behind going paleo with the movement’s pioneer, as well as with an evolutionary biologist. Is it true that our genes haven’t changed much since our hunter-gatherer days?
Plus, a surprising dental discovery is nothing for cavemen to smile about.
And another fad diet that has a historical root: the monastic tradition of 5:2 – five days of eating and two days of fasting.
It’s our monthly look at critical thinking, Skeptic Check … but don’t take our word for it.

ENCORE Computers and DNA have a few things in common. Both use digital codes and are prone to viruses. And, it seems, both can be hacked. From restoring the flavor of tomatoes to hacking into the president’s DNA, discover the promise and peril of gene tinkering.
Plus, computer hacking. Just how easy is it to break into your neighbor’s email account? What about the CIA’s?
Also, one man’s concern that radio telescopes might pick up an alien computer virus.

Imagine not knowing where you are – and no one else knowing either. Today, that’s pretty unlikely. Digital devices pinpoint our location within a few feet, so it’s hard to get lost anymore. But we can still get stranded.
A reporter onboard an Antarctic ship that was stuck for weeks in sea ice describes his experience, and contrasts that with a stranding a hundred years prior in which explorers ate their dogs to survive.
Plus, the Plan B that keeps astronauts from floating away forever … how animals and plants hitch rides on open sea to populate new lands … and the rise of the mapping technology that has made hiding a thing of the past.

Picture a cockroach skittering across your kitchen. Eeww! Now imagine it served as an entrée at your local restaurant. There’s good reason these diminutive arthropods give us the willies – but they may also be the key to protein-rich meals of the future. Get ready for cricket casserole, as our relationship to bugs is about to change.
Also, share in one man’s panic attack when he is swarmed by grasshoppers. And the evolutionary reason insects revolt us, but also why the cicada’s buzz and the beetle’s click may have inspired humans to make music.
Plus, the history of urban pests: why roaches love to hide out between your floorboards. And Molly adopts a boxful of mealworms.

You must not remember this. Indeed, it may be key to having a healthy brain. Our gray matter evolved to forget things; otherwise we’d have the images of every face we saw on the subway rattling around our head all day long. Yet we’re building computers with the capacity to remember everything. Everything! And we might one day hook these devices to our brains.
Find out what’s it’s like – and whether it’s desirable – to live in a world of total recall. Plus, the quest for cognitive computers, and how to shake that catchy – but annoying – jingle that plays in your head over and over and over and …

ENCORE Zombies are making a killing in popular culture. But where did the idea behind these mythical, cerebrum-supping nasties come from? Discover why they may be a hard-wired inheritance from our Pleistocene past.
Also, how a whimsical mathematical model of a Zombie apocalypse can help us withstand earthquakes and disease outbreaks, and how the rabies virus contributed to zombie mythology.
Plus, new ideas for how doctors should respond when humans are in a limbo state between life and death: no pulse, but their brains continue to hum.

ENCORE You can get your point across in many ways: email, texts, or even face-to-face conversation (does anyone do that anymore?). But ants use chemical messages when organizing their ant buddies for an attack on your kitchen. Meanwhile, your human brain sends messages to other brains without you uttering a word.
Hear these communication stories … how language evolved in the first place… why our brains love a good tale …and how Facebook is keeping native languages from going extinct.

ENCORE Mooooove over, make way for the cows, the chickens … and other animals! Humans can learn a lot from our hairy, feathered, four-legged friends. We may wear suits and play Sudoku, but Homo sapiens are primates just the same. We’ve met the animal, and it is us.
Discover the surprising similarity between our diseases and those that afflict other animals, including pigs that develop eating disorders. Plus, what the octopus can teach us about national security … how monkeying around evolved into human speech … and the origins of moral behavior in humans.

We all may prefer the goldilocks zone – not too hot, not too cold. But most of the universe is bitterly cold. We can learn a lot about it if we’re willing to brave a temperature drop.
A chilly Arctic island is the closest thing to Mars-on-Earth for scientists who want to go to the Red Planet. Meanwhile, the ice sheet at the South Pole is ideal for catching neutrinos – ghostly particles that may reveal secrets about the nature of the universe.
Comet ISON is comet ice-off after its passage close to the Sun, but it’s still giving us the word on solar system’s earliest years.
Also, scientists discover the coldest spot on Earth. A champion chill, but positively balmy compared to absolute zero. Why reaching a temperature of absolute zero is impossible, although we’ve gotten very, very close.

Monsters don’t exist. Except when they do. And extinction is forever, except when it isn’t. So, which animals are mythical and which are in hiding?
Bigfoot sightings are plentiful, but real evidence for the hirsute creature is a big zilch. Yet, the coelacanth, a predatory fish thought extinct, actually lives. Today, its genome is offering clues as to how and when our fishy ancestors first flopped onto land.
Meanwhile, the ivory-billed woodpecker assumes mythic status as it flutters between existence and extinction. And, from passenger pigeons to the wooly mammoth, hi-tech genetics may imitate Jurassic Park, and bring back vanished animals.

Imagine a world without algebra. We can hear the sound of school children applauding. What practical use are parametric equations and polynomials, anyway? Even some scholars argue that algebra is the Latin of today, and should be dropped from the mandatory curriculum.
But why stop there? Maybe we should do away with math classes altogether.
An astronomer says he’d be out of work: we can all forget about understanding the origins of the universe, the cycles of the moon and how to communicate with alien life. Also, no math = no cybersecurity + hackers (who have taken math) will have the upper hand.
Also, without mathematics, you’ll laugh < you do now. The Simpsons creator Matt Groening has peppered his animated show with hidden math jokes.
And why mathematics = love.
