The science of storms.

ENCORE We all talk about the weather. And now scientists are doing something about it: providing more accurate warnings before big storms hit. Discover how smart technology – with an eye on the sky – is taking monster weather events by storm.

Plus, why severe weather events caused by a warming planet may trigger social and economic chaos.

Also, meet the storm chaser who runs toward tornadoes as everyone else flees… and why your cell phone goes haywire when the sun kicks up a storm of its own.

Reincarnation, hibernation, and suspended animation.

ENCORE Could you have had a past life? Is it possible that some part of you is the reincarnation of a person – or maybe an animal – that lived long ago?

We’ll hear the story of a young boy who started having nightmares about a plane crash. His parents thought he was the reincarnation of a downed, World War II fighter pilot. But his story might not fly.

Also … is there any biological basis for reincarnation? Animals that indulge in the big sleep.

Boost your storage capacity.

ENCORE You must remember this… wait, wait... I had it… on the tip of my tongue… (Memory is a tricky thing and most of us would like to improve it)… oh, yes: Discover the secrets of stupefying, knock-your-socks-off recall by a U.S. Memory Champion.

Also, almost everything we know about memory comes from the life of one man born in 1926 and known as H.M., the world’s “most unforgettable amnesiac.”

Plus, the sum total of the global data storage capacity in hard drives, thumb drives, the Internet, you name it… guess how many exabytes it comes to?

Nov 18, 2012
The quest for longevity.

ENCORE We all have to go sometime, and that final hour is the mother of all deadlines. But scientists are working to file an extension. Discover how far we can push the human expiration date.

Plus, the animal with the shortest lifespan and the chemistry that causes your pot-roast to eventually clothe itself in fuzzy green mold.

Also, a clock that won’t stop ticking (for 10,000 years) and our love-hate relationship with that long-lived hydrocarbon that keeps our snack cakes fresh: plastic!


Nov 04, 2012
Our shrinking planet.

The Internet is not the only globally-uniting phenomenon. Viruses and bacteria can circle the globe as fast as we can, and the effects can be devastating. Discover what it takes for an animal disease to become a human pandemic. Also, was hurricane Sandy a man-made disaster? The future of severe storms and climate change.

Plus, the view of our science from abroad: why Brits have no trouble accepting the theory of evolution but Americans do. And what about a new annex for Silicon Valley – 12 miles out to sea?


Oct 21, 2012
Finding artifacts from on-high.

ENCORE Indiana Jones meets Star Trek in the field of space archaeology. Satellites scan ancient ruins so that scientists can map them without disturbing one grain of sand. Discover how some archaeologists forsake their spades and brushes in favor of examining historic sites from hundreds of miles high.

Also, if you were to hunt for alien artifacts – what would you look for? Why ET might choose to send snail mail rather than a radio signal.

Plus, the culture of the hardware we send into space, and roaming the Earth, the moon, and Mars the Google way.


Oct 14, 2012
Exotic travel destinations.

If you’re itching to get away from it all, really get away from it all, have we got some exotic destinations for you. Mars … Jupiter’s moon Europa … asteroids . Tour some enticing worlds that are worlds away, but ripe for exploration.

Also, why private spaceships may be just the ticket for getting yourself into space, unless you want to wait for a space elevator.

And, why one science journalist boasts of an infectious, unabashed, and unbridled enthusiasm for space travel.


Oct 07, 2012
Originality in science.

ENCORE By thinking different, scientists can make extraordinary breakthroughs. Learn about the creative cogitation that led to the discovery of dark matter and the invention of a.c. power grids, disinfectant, and the Greek “death ray.” Also, whether one person’s man of genius is another’s mad scientist.

And, the scientist who claims pi is wrong and biopunks who tinker with DNA – in their kitchens and on the cheap.

Plus, from string theory to the greenhouse effect – how metaphor sheds light on science. Discover why your brain is like a rain forest (that’s a simile!).


Sep 30, 2012
Mass hysteria in Le Roy, N.Y.

Stuttering speech and facial tics are among the strange symptoms that swept through a New York high school. Discover what’s behind the odd outbreak, and why one sociologist sees parallels to Salem, Massachusetts 300 years ago.

Also, an update on the cellphone cancer debate, and why one congressman wants warning labels on all new phones.

Plus, the ultimate cleanse: giving up on food to survive on light and air. We investigate the claims of Breatharians.

It’s Skeptic Check … but don’t take our word for it!


Sep 23, 2012
SETI number crunching, curing disease, and knowing everything about yourself.

It’s all in the numbers. The trick is, finding what you’re looking for. But that’s the name of the game with big data. We have a giga-gigabyte of information, and combing through it will lead to new cures for disease, new discoveries about the cosmos, or clues to our social and economic behavior.

But is big data Big Brother? You leave a little bit of yourself behind with each mouse click. Discover how surveillance and privacy issues bubble out of the mix, as the terabytes keep flowing in.


Sep 16, 2012
I feel your vibe.

ENCORE “I feel your vibe!” Well, that describes a number of fabled locales that claim to pulse with mysterious energy – perhaps prompting books to fly across the room or airplanes to vanish into thin air. But what’s the science behind it?

We examine spots marked with an X, for “extraordinary” – from a haunted house to the Bermuda Triangle – to sort out natural from supernatural phenomena.

Plus, what causes the aurora borealis… a haywire Russian space probe… and just what the heck is an “energy vortex,” anyway?


Sep 09, 2012
Our mirror in the lab

Before you chase it with a broom, consider this – without the rat, we might miss critical insights into the nature of stress, cancer … and even love. These furry, red-eyed rodents have a unique role in medical research – and a ubiquitous companion to our urban lives.

Discover the origins of the albino laboratory rat … what rat laughter sounds like, and why these four-legged fur balls don’t fall victim to the pressure of the rat race … but we do.

To need air is human.

To need air is human. Our lungs thank us for each breath we take. But air is more than a transporter of O2. It shapes our weather, keeps birds aloft and moves spores from here to there. A cubic foot of air is anything but “empty” (hot dog grease particles, anyone?).

The same goes for space (minus the hot dog grease). It’s a happening place. Discover why interstellar space is more than a whole lot o’ nothing; and what happens when the Voyager spacecraft leaves our solar system. Plus, catch a skydiver in action!

A credulity potpourri.

ENCORE If Bigfoot walks through a forest and no one sees him, does he exist? It’s the job of paranormal investigator Joe Nickell to find out! Discover whether eyewitness accounts are reliable when it comes to tracking down the hirsute big guy and other monsters.

Also, on the subject of “seeing is believing”: how magic fools the brain.

Plus, in our potpourri show: can music boost brain power? A new study says listening to music makes brains happy. Does this support the dubious “Mozart Effect,” that claims listening to Wolfie’s compositions boosts IQ?


Aug 19, 2012
Meet your computer overlords.

ENCORE When the IBM computer, Watson, snatched the “Jeopardy” title from its human competition, that raised the question of just how smart are machines? Could artificial intelligence ever beat humans at their own game… of being human?

Hear why an A.I. expert says it’s time to make peace with your P.C.; the machines are coming. Also, why technology is already self-evolving, and presenting its own demands. Find out what technology wants.

We dig the Red Planet.

We dig the Red Planet! And so does Curiosity. After a successful landing, and a round of high-fives at NASA, the latest rover to land on Mars is on the move, shovel in mechanical hand.

Discover how the Mars Science Laboratory will hunt for the building blocks of life, and just what the heck a lipid is. Plus, how to distinguish Martians from Earthlings, and the tricks Mars has played on us in the past (canals, anyone?).

Also, want to visit Mars firsthand? We can point you to the sign-up sheet for a manned mission. The catch: the ticket is one-way.

Meet the alternatives.

ENCORE You know the joke about the car and the snail. Look at that escargot? Well, snails may be the only thing not powering the automobiles of the future. Trees, grass, algae, even the garbage you toss on the sidewalk has potential for conversion into biofuel. What is America’s next top model fuel? Join us on a tour of the contenders.

Meet a man who’s mad about miscanthus … an astrobiologist’s attraction to algae... and the blueprint for building your own biofuel bugs.
