Big Picture Science for Monday 25 May 2015 - Skeptic Check: After the Hereafter

Image for Big Picture Science weekly radio show
Big Picture Science - Skeptic Check: After the Hereafter

There are few enduring truths, but one is that no one gets out of life alive. What’s less certain is what comes next. Does everything stop with death, or are we transported to another plane of existence? First-hand accounts of people who claim to have visited heaven are offered as proof of an afterlife. Now the author of one bestseller admits that his story was fabricated.

We’ll look at the genre of “heaven tourism” to see if it has anything to say about the possible existence of the hereafter, and why the idea of an afterlife seriously influences how we live our lives on Earth.

Also, a neurologist describes what is going on in the brain during near-death and other out-of-body experiences.

It’s Skeptic Check, our monthly look at critical thinking … but don’t take our word for it!

Big Picture Science for Monday 10 November 2014 - Skeptic Check: Are You Sure You're Sure?

Image for Big Picture Science weekly radio show
Big Picture Science - Skeptic Check: Are You Sure You're Sure?

Nuclear fission powers the Sun. Or is it fusion? At any rate, helium is burned in the process, of that you are certain. After all, you read that article on astronomy last week*.

You know what you know. But you probably don’t know what you don’t know. Few of us do. Scientists say we’re spectacularly incompetent at recognizing our own incompetency, and that sometimes leads to trouble.

Find out why wrongness is the by-product of big brains and why even scientists – gasp! – are not immune. Plus, a peek into the trash bin of history: the biggest scientific blunders and the brighter-than-bright brains that made them. Including Einstein.

*Oh, and the Sun burns hydrogen to produce helium. But then, you knew that.

Big Picture Science for 07/28/14 - Replace What Ails You

Image for Big Picture Science weekly radio show
Big Picture Science - Replace What Ails You

Germs can make us sick, but we didn’t know about these puny pathogens prior to the end of the 19th century. Just the suggestion that a tiny bug could spread disease made eyes roll. Then came germ theory, sterilization, and antibiotics. It was a revolution in medicine. Now we’re on the cusp of another one. This time we may cure what ails us by replacing what ails us.

Bioengineers use advancements in stem cell therapy to grow red and white cells for human blood. Meanwhile, a breakthrough in 3D printing: scientists print blood vessels and say that human organs may be next.

Plus, implanting electronic grids to repair neural pathways. Future prosthetics wired to the brain may allow paralyzed limbs to move.

We begin with the story of the scientist who discovered the bacteria that caused tuberculosis, and the famous author who revealed that his cure for TB was a sham.

Big Picture Science for 07/14/14 - Skeptic Check: About Face

Image for Big Picture Science weekly radio show
Big Picture Science - Skeptic Check: About Face

ENCORE: Face it – humans are pattern-seeking animals. We identify eyes, nose and mouth where there are none. Martian rock takes on a visage and the silhouette of Elvis appears in our burrito. Discover the roots of our face-tracking tendency – pareidolia – and why it sometimes leads us astray.

Plus, why some brains can’t recognize faces at all … how computer programs exhibit their own pareidolia … and why it’s so difficult to replicate human vision in a machine

Big Picture Science for 04/21/14 - Happily Confused

Image for Big Picture Science weekly radio show
Big Picture Science - Happily Confused

Do you feel happy today? How about happily disgusted? Maybe sadly surprised, or sadly disgusted? Human emotions are complex. But at least they’re the common language that unites us all – except when they don’t. A tribe in Namibia might interpret our expression of fear as one of wonderment. And people with autism don’t feel the emotions that others do.

So if you’re now delightfully but curiously perplexed, tune in and discover the evolutionary reason for laughter … how a computer can diagnose emotional disorders that doctors miss … and why the world’s most famous autistic animal behaviorist has insight into the emotional needs of cattle.

Image for Big Picture Science weekly radio show
Big Picture Science - Group Think

ENCORE: If two is company and three a crowd, what’s the ideal number to write a play or invent a new operating system? Some say you need groups to be creative. Others disagree: breakthroughs come only in solitude.

Hear both sides, and find out why you always have company even when alone: meet the “parliament of selves” that drive your brain’s decision-making.

Plus, how ideas of societies lead them to thrive or fall, and why educated conservatives have lost trust in science.

Big Picture Science - Skeptic Check: Forget with the Program

ENCORE Just remember this: memory is like Swiss cheese. Even our recollection of dramatic events that seem to sear their images directly onto our brain turn out to be riddled with errors. Discover the reliability of these emotional “flashbulb” memories.

Also, a judge questions the utility of eyewitness testimony in court. And, don’t blame Google for destroying your powers of recall! Socrates thought the same thing about the written word.

Plus, Brains on Vacation!

Big Picture Science - Oh, Rats!

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.

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?

And, skeptic Phil Plait on why the so-called “super moon theory” doesn’t predict devastating earthquakes.

Big Picture Science - Seth's Storm Shelter

Expect the unexpected when we go digging in Seth’s storm shelter – who knows what we’ll find! In this cramped never-never land, tucked between piles of dehydrated food packets and old civil defense helmets, we stumble (but don’t step) upon marauding ants … a mission to Pluto…. “evidence” of a spaceship crash … the Apollo astronaut who shot the “Earth Rise” photograph … and Jonah Lehrer meditating on creativity.

Tune in, find out and, help move this box of canned soup, will you?

Big Picture Science - Found in Space

ENCORE If someone asks where you get off, you can now respond with precision. Satellites and computers spit out coordinates accurate to a few paces. And digital maps stand the Copernican principle on its head – putting you at the center of everything (how does it feel?).

Find out how today’s maps are shuffling our world view. Also, how does a rat navigate a maze without GPS? Hear of the plotting that goes on in that tiny rodent brain.

Plus, mapping the universe and pinpointing just where we are in cosmic time – lucky for us, human evolution is right on schedule.

Are We Alone - Thanks for the Memories

ENCORE Memories are slippery things – some are crystal clear, others more like a muddy pool, and some… well, they seem to vanish completely.

Scientists admit that memory is all very complicated, but one piece of the puzzle lies in how we age – we’ll hear the latest research.

Meanwhile, meet the man who digitally logged his every waking moment – and why maybe the secret to happiness isn’t in remembering but in forgetting.

Plus, the case for deleting data from your hard-drive… and from your brain itself.

Are We Alone for 02/28/11 - Skeptic Check: Diluted Thinking?

Image for Are We Alone weekly radio show
Are We Alone - Skeptic Check: Diluted Thinking?

The weaker the mixture, the stronger the potency. That paradox is a central tenet of homeopathy. More than 200 years old and developed long before germ theory, the practice is the fastest growing form of alternative medicine worldwide.

Proponents say its diluted remedies cure disease. Most scientists maintain there’s nothing in homeopathic solution but water. We’ll hear the arguments, and also the role placebos might be playing in the cure.

Plus, skeptic Phil Plait voyages to the edge of the solar system where a new planet has been discovered … maybe!

And, consider our brains: the product of millions of years of evolution. So why aren’t we more consistent in our reasoning?

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