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.
And our Hollywood skeptic poses as a psychic for Dr. Phil, while our Dr. Phil (Plait) investigates the authenticity of a life-bearing meteorite.

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.
Travel through millennia, back through mega and giga years, for a sense of what can occur over deep time, from the Cambrian Explosion to the age of the dinosaurs to the rise of Homo sapiens.

“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.
Plus, an award-winning public-private research project changes the way we use GPS … and a BBC reporter on the fate of international projects when Americans hang up their lab coats.
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.
Discovering bacteria on Mars would be big news. But nothing would scratch our alien itch like making contact with intelligent life. Hear why one man is impatient for the discovery, and also about the new tools that may speed up the “eureka” moment. One novel telescope may help us find E.T. at home, by detecting the heat of his cities.
Also, the father of modern SETI research and how decoding the squeals of dolphins could teach us how to communicate with aliens.
