Say What?

Mon, 2010-08-30 07:00

ENCORE There’s no escape from the chattering classes – they talk, squawk, squeal and sing all around us. Every animal communicates in some form – it’s essential for survival. They’ve evolved to understand each other … but do we understand them?

Find out what’s coded in humpback whale song and whether human-cetacean dialogue is possible… how information theory reveals communication patterns within the animal kingdom… how plants call out to animals to protect them… and why only humans evolved language.

Rxs Get Personal

Mon, 2010-08-09 07:00

ENCORE Medicine’s back.. and this time it’s personal. Get ready to have your genome read… your brain scanned… and undergo a chemical analysis so detailed, it’ll reveal the Twinkie you had for lunch. Everyone’s different, and reading those differences at the level of the gene may provide a more accurate profile of health and how to treat disease. But are you ready to know what’s wrong with you?

Discover the future of personalized medicine with biologist Craig Venter, as well as a man who turned his body over to the new science. Learn what his tests revealed.

Plus, why stem cell research really is a horse race. And, why getting sick is sometimes the best thing.

Bug Off!

Mon, 2010-08-02 07:00

What you can’t see … can make you sick. Humans have been battling viruses and bacteria since the beginning of time. The malaria parasite has been keeping deadly company with us for 500,000 years. King Tut had it and so did Julius Caesar. What’s keeping this bug going today?

Also, how disease almost halted the most ambitious engineering project in the world … how elite disease detectives puzzle out perplexing epidemics … And – could tiny bugs from spaaace, ace, ace be our ancestors?

What's Your Poison?

Mon, 2010-07-26 07:00

“Aspirin and Old Lace?” Okay, it would take a bottle full of pills in a glass of elderberry wine to really harm you, but aspirin can be deadly. So can too much of anything, including water. Dose is key in toxicology, after all, but there are some poisons that can do deadly work in tiny amounts.

Hear about the chemistry of poisons … why Botox may freeze your emotions as well as your face… which animal is most lethal to humans… and how 19th-century poisoners got away with murder – until the birth of forensic science.

Grave Matters

Mon, 2010-07-19 07:00

ENCORE We could choose not to pay income tax and suffer the consequences. But we can’t avoid death. The biological functions of all organisms eventually cease. But why should this be? Find out why animals die and meet one creature that is biologically immortal.

Plus, a trip to the Body Farm where decaying bodies help science…how we might cheat the Big Sleep with drugs… why Mexican cemeteries look like villages… and a doctor’s fight against one of the world’s deadliest diseases.

Skeptic Check: Playing Doctor

Mon, 2010-07-12 07:00

ENCORE A new herbal supplements is on the shelf, and it claims to improve memory. Should you take it? It’s not easy to sort through the firehose of health and nutrition advice that comes at us daily. Find out how to get healthy about health advice, plus hear the story of Bernarr Macfadden, the eccentric who kicked off America’s fitness craze; he believed that eating less was good for you, but he didn’t believe germ theory.

Plus, our Hollywood skeptic spills his guts and other entrails for a phony class for nurses and Phil Plait gives us the latest lapse in critically-thinking brains.

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

Rend Me Your Ears

Mon, 2010-07-05 07:00

Shh – can you keep it down? Nope. Not unless you want to do away with civilization. Our buzzing, humming, whirling, machine-driven world is a poster child for technological progress, right? As is hearing loss. It’s driven one man to search the world for silence. We’ll hear what he didn’t hear, and what Einstein predicted we should hear in deep space, where gravitational waves may reveal the hidden sounds of the universe, including the birth of black holes.

Home Brew Science

Mon, 2010-06-28 07:00

The recipe for being a scientist was easy in the old days… just be born into a rich family, have an interest in nature and plenty of time to indulge yourself. But are the days of gentlemen scientists over? Maybe not.

We go to the Maker Faire and check out how small-scale projects have big-scale ambitions.

Also, how everyday experience often tells us something profound about the universe.

Swarm in Here... or Is It Just Me?

Mon, 2010-06-21 07:00

An ant … can’t … move a rubber tree plant… but the colony can. As a group, ants are an efficient, organized, can-do bunch. And a model for humans trying to manage complex systems.

Find out about the eerie collective intelligence of animals, and how an MIT researcher is hoping to put humans to work collaboratively to solve problems like climate change.

Also … hear how research into flocking behavior helps Hollywood film a herd of stampeding dinosaurs.

Written in Code

Mon, 2010-06-14 07:00

Genes – what are they good for? Absolutely… something. But not everything. Your “genius” genes need to be turned on – and your environment determines that. Find out how to unleash your inner-Einstein, and what scientists learned from studying the famous physicist’s brain.

Also, the bizarre notion that your children inherit not just your genes, but also the consequences of your habits – smoking, stress, diet, and other behaviors that turn the genes on.

Plus Francis Collins on affordable personal genomes, and a man who decoded his own DNA in under a week.

Seth's Garage

Mon, 2010-06-07 07:00

ENCORE It’s always a surprise to go digging in Seth’s garage – who knows what we’ll find! In this impressive heap of paraphernalia, tucked between boxes of old radio tubes and hydraulic jacks, we stumble upon the secrets to our galaxy’s central black hole… witness the dance of the PhD theses… uncover the genome of milk (while moo-ving boxes) and … hey? Who’s that crunching numbers in the corner? It’s astrophysicist Mario Livio addressing the mathematical mysteries of universe.

Life of Brain

Mon, 2010-05-24 07:00

ENCORE We should award frequent travel miles to your brain. After all, it’s evolved a long way from the days of guiding brachiation from tree-to-tree to become the three pounds of web-surfing, Sudoku-playing powerhouse it is today. But a suite of technologies may expand human brains further still.

From smart pills to nano-wires: discover the potential – and peril – of neuro-engineering to repair and enhance our cognitive function.

Also, how our brains got so big in the first place: a defense of the modern diet.

Skeptic Check: Fraudcast News

Mon, 2010-05-17 07:00

There are a lot of scientific claims out there – how do you separate the good from the bad and the outright fraudulent? Experts failed to do so for years in the case of a physicist whose published papers claimed the invention of a new bio-based transistor. Plus, other stories of deceit – such as the scientist who stooped to coloring mouse fur with markers.

Also, why climate science is solid, but its scientists need to be more open with the public.

And, from the undersea “bloop” to the Denver airport conspiracy theory. Why urban myths are so popular.

Plus, Phil Plait describes someone’s plans to meditate away the Gulf of Mexico oil spill.

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