Big Picture Science for Monday 06 April 2015 - Raising the Minimum Age

Big Picture Science - Raising the Minimum Age

We all try to fight it: the inexorable march of time. The fountain of youth doesn’t exist, and all those wrinkle creams can’t help. But modern science is giving us new weapons in the fight against aging. So how far are we willing to go?

Hear when aging begins, a summary of the latest biotech research, and how a lab full of youthful worms might help humans stay healthy.

Also, a geneticist who takes a radical approach: collect the DNA that codes for longevity and restructure our genome. He finds inspiration – and perhaps genes as well – in the bi-centenarian bowhead whale.

But what if age really is mind over matter? A psychologist’s extraordinary thought experiment with septuagenarian men turns back the clock 20 years. Will it work on diseases such as cancer as well?

Guests:

• Gordon Lithgow – Geneticist, Buck Institute for Research on Aging, Novato, California
• Manish Chamoli – Post-doctoral researcher, Buck Institute for Research on Aging
• George Church – Professor of Genetics, Harvard Medical School, author of Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves
• Ellen Langer – Professor of Psychology, Harvard University and author of Counterclockwise: Mindful Health and the Power of Possibility

Big Picture Science for Monday 02 March 2015 - Skeptic Check: The Me in Measles

Big Picture Science - Skeptic Check: The Me in Measles

Wondering whether to vaccinate your children? The decision can feel like a shot in the dark if you don’t know how to evaluate risk. Find out why all of us succumb to the reasoning pitfalls of cognitive and omission bias, whether we’re saying no to vaccines or getting a tan on the beach.

Plus, an infectious disease expert on why it may take a dangerous resurgence of preventable diseases – measles, whooping cough, polio – to remind us that vaccines save lives.

Also, a quaint but real vaccine fear: that the 18th century smallpox vaccine, made from cowpox, could turn you into a cow!

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

Guests:

• Paul Offit – Infectious disease specialist at the Children’s Hospital of Philadelphia
• Neil deGrasse Tyson – Astrophysicist, director of the Hayden Planetarium in New York City
• Adam Korbitz – Lawyer specializing in space law
• Andrew Maynard – Professor of environmental health science, director, Risk Science Center, University of Michigan

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

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.

Guests:

• David Dunning – Psychologist, Cornell University. His cover story, “We Are All Confidence Idiots,” appeared in the November/December issue of The Pacific Standard.
• Robert Burton – Neurologist, author, On Being Certain: Believing You Are Right Even When You’re Not and A Skeptic’s Guide to the Mind: What Neuroscience Can and Cannot Tell Us About Ourselves
• Brendan Nyhan – Political scientist, Dartmouth College
• Mario Livio – Astrophysicist, Space Telescope Science Institute, author, Brilliant Blunders: From Darwin to Einstein – Colossal Mistakes by Great Scientists That Changed Our Understanding of Life and the Universe

Big Picture Science for 01/20/14 - Forget to Remember

Big Picture Science - Forget to Remember

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 …

Guests:

• Ramamoorthy Ramesh – Materials physicist, deputy director of science and technology, Oakridge National Lab
• Michael Anderson – Neuroscientist, Memory Control Lab, MRC Cognition and Brain Sciences Unit at the University of Cambridge in the U.K.

Big Picture Science for 05/06/13 - Stomach This

Big Picture Science - Stomach This

Not all conversation is appropriate for the dinner table – and that includes, strangely enough, the subject of eating. Yet what happens during the time that food enters our mouth and its grand exit is a model of efficiency and adaptation.

Author Mary Roach takes us on a tour of the alimentary canal, while a researcher describes his invention of an artificial stomach. Plus, a psychologist on why we find certain foods and smells disgusting.

And, you don’t eat them but they could wiggle their way within nonetheless: surgical snakebots.

Guests:

• Mary Roach – Author, most recently, of Gulp: Adventures on the Alimentary Canal
• Martin Wickham – Head of Nutrition, Leatherhead Food Research, U.K.
• Paul Rozin – Professor of psychology, University of Pennsylvania

Big Picture Science for 04/15/13 - Skeptic Check: Forget with the Program

Big Picture Science - Skeptic Check: Forget with the Program

Big Picture Science for 02/13/12 - Aware am I?

Big Picture Science - Aware am I?

Big Picture Science for 07/11/11 - The Big Picture

Big Picture Science - The Big Picture: Science’s Biggest Questions

How did life begin? What’s the universe made of, and what’s the nature of consciousness?

These are truly some of the biggest puzzlers in science, but answers are in the offing.

We consider the modern-day hunt for life beyond Earth, as well as a new theory of consciousness: could it be merely an illusion to entertain us and make our lives more worthwhile?

Also, after thousands of years of examining the heavens, are we finally learning the true nature of the cosmos?

Guests:

• Marc Kaufman – Reporter for the Washington Post, and author of First Contact: Scientific Breakthroughs in the Hunt for Life Beyond Earth
• Carolyn Porco – Planetary scientist and leader of the Cassini Imaging Team
• Michael Russell – Research Scientist at the Jet Propulsion Laboratory

Are We Alone for 01/31/11 - Skeptic Check: ESP or Think Again

Are We Alone - Skeptic Check: ESP or Think Again

You’re right: it’s a show about ESP. And, correct again: we’re excited about the publication of a paper that claims precognition exists. You’ve already divined what our paranormal investigator says about the paper, whether the statistics that it cites are significant, and what the editor-in-chief of a major scientific journal has to say on the tricky matter of publishing such a result at all.

You’re not surprised that Brains on Vacation takes on the matter of Armageddon-by-exploding-star, because, you knew that. You also knew that it will be an excellent show. But, tune in anyway – consider it a repeat.

Guests:

• Bruce Alberts – Editor-in-chief of Science
• Jim Underdown – Executive Director, Center for Inquiry – Los Angeles
• Jeff Rouder – Quantitative psychologist, University of Missouri
• Phil Plait – Skeptic and keeper of the website badastronomy.com
