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.
Meet the songwriter who has zombies on the brain …. and we chase spaced-out animated corpses in the annual Run-For-Your-Lives foot race.

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.

ENCORE We’ve all had an “oops” moment. Scientists are no exception. Sometimes science stumbles in the steady march of progress. Find out why cold fusion is a premier example why you shouldn’t hold a press conference before publishing your results. Also, how to separate fumbles from faux-science from fraud.
Plus, why ignorance is what really drives the scientific method.

After the winds and water of Typhoon Haiyan abated, grief and hunger swept though the Philippines, along with the outbreak of disease. Are monster storms the new normal in a warmer world? Some scientists say yes, and if so, climate change is already producing real effects on human life and health.
A hotter planet will serve up casualties from natural disasters, but also higher rates of asthma, allergies and an increase in mosquito-borne diseases. It is, according to one researcher, the greatest challenge of our time, straining health care efforts worldwide. But could a “medical Marshall Plan” save us?
Also, why the conservative estimates from the U.N.‘s climate change group don’t help people prepare for worst-case scenarios. And, a controversial approach to saving our overburdened planet: a serious limit on population growth.

A computer virus that bombards you with pop-up ads is one thing. A computer virus that shuts down a city’s electric grid is another. Welcome to the new generation of cybercrime. Discover what it will take to protect our power, communication and transportation systems as scientists try to stay ahead of hackers in an ever-escalating game of cat and mouse.
The expert who helped decipher the centrifuge-destroying Stuxnet virus tells us what he thinks is next. Also convenience vs. vulnerability as we connect to the Internet of Everything. And, the journalist who wrote that Google was “making us stupid,” says automation is extracting an even higher toll: we’re losing basic skills. Such as how to fly airplanes.

ENCORE Time keeps on ticking, ticking … and as it does, evolution operates to produce remarkable changes in species. Wings may appear, tails disappear. Sea creatures drag themselves onto the shore and become landlubbers. But it’s not easy to grasp the expansive time scales involved in these transformative feats.

“Sorry, closed for business.” That sign hung on doors of national laboratories when the US government shut down. What that meant for one Antarctic researcher: her critically important work was left out in the cold.
So just what do we lose when public funds for science fade? The tools for answering big questions about our universe for one, says a NASA scientist … while one of this year’s Nobel Prize winners fears that it is driving our young researchers to pursue their work overseas.
Yet one scientist says public funding isn’t even necessary; privatizing science would be more productive.

It was the most famous invasion that never happened. But Orson Welles’ 1938 “War of the Worlds” broadcast sure sounded convincing as it used news bulletins and eyewitness accounts to describe an existential Martian attack. The public panicked. Or did it? New research says that claims of mass hysteria were overblown.
On the 75th anniversary of the broadcast: How the media manufactured descriptions of a fearful public and why – with our continued fondness for conspiracies – we could be hoodwinked again.
Plus, journalism ethics in the age of social media. Can we tweet “Mars is attacking!” with impunity?
And why we’re obsessed with the Red Planet.

Your brain is made up of cells. Each one does its own, cell thing. But remarkable behavior emerges when lots of them join up in the grey matter club. You are a conscious being – a single neuron isn’t.
Find out about the counter-intuitive process known as emergence – when simple stuff develops complex forms and complex behavior – and all without a blueprint.
Plus self-organization in the natural world, and how Darwinian evolution can be speeded up.
