Over the past several episodes, Skepticality has interviewed some of the notable scientists featured in the new pro-Intelligent Design documentary Expelled: No Intelligence Allowed.  This week, the last word on the controversy goes to Dr. Randy Olson, the biologist-turned-filmmaker whose 2006 documentary Flock of Dodos: The Evolution – Intelligent Design Circus examined the communication breakdown between the science community and the rest of the world on the subject of evolution.   Dr. Olson strives to improve the reputation of science in the court of public opinion, where the Religious Right and Intelligent Design movements continue to wedge their way in by "teaching the controversy."  On his "Shifting Baselines" blog, Dr. Olson was one of the first scientists to express concern that the well-funded Expelled was likely to succeed in selling its message to a tremendous number of people. The "dodos" of the blogosphere responded with incredulity.   At the request of many skepticality listeners, we're pleased to feature this week's interview with Dr. Olson about his controversial opinions — and about his new film, Sizzle: A Global Warming Comedy.

The contentious pro-Intelligent Design film Expelled: No Intelligence Allowed  is now in its second week of wide release, and the controversy is far from over.  This week on Skepticality, Swoopy talks with Dr. Eugenie Scott about her participation in Expelled, her thoughts on seeing the film — and the "Expelled: Exposed" website, created by the National Center for Science Education (where Dr. Scott serves as the Executive Director). Beyond the Expelled frenzy, Dr. Scott talks about her work with the NCSE, the future of science education, and what the average person can do to improve the public perception and understanding of science.

This week on Skepticality we talk to two good friends, both skeptics and podcasters making an impact in their areas of expertise. Slavko Halatyn (known to his many fans as simply "Slau") has enjoyed a rich career as both a music producer and award-winning recording artist.  Derek talks with Slau about his work with other artists (like skeptical favorite George Hrab), being an early adopter of podsafe music — and the links between his career, his world view, and his becoming legally blind at the age of 21. Author Scott Sigler sent a shot across the bow of mainstream publishing when, after first giving away his novel Ancestor for free as a PDF, the printed retail version then broke the Amazon.com top 10.  As a result, Scott earned himself a seat at the table and a deal with Crown books.  We talk to Scott about his new novel Infected — released on April 1st and already a bestseller.

In the upcoming a pro-Intelligent Design documentary Expelled: No Intelligence Allowed (starring comedy actor Ben Stein), several notable scientists speak in support of science and evolution, including evolutionary biologist (and outspoken atheist) Richard Dawkins, science blogger PZ Meyers, and Skeptics Society founder Michael Shermer. As Swoopy finds out this week when she talks with Dawkins and Shermer, Expelled is not the film these scientists agreed to be a part of—nor were their experiences at advanced screenings what they expected….

Last week, a widely circulated Associated Press story reported that "a vast array of pharmaceuticals — including antibiotics, anti-convulsants, mood stabilizers and sex hormones — have been found in he drinking water supplies of at least 41 million Americans." Derek and Swoopy look beyond the headline hype in their interview with Dr. Shane Snyder, who published his first study on "Screening of Drinking Water for Possible Endocrine Disrupting Compounds" over ten years ago.  As a doctor of Environmental Toxicology and Zoology, Dr. Snyder has devoted most of his career to studying the evidence of chemical, environmental and pharmaceutical compounds in the water supply—and what harm, if any, it poses to the organisms that utilize it.

Can a kids' science and critical thinking television program be both entertaining and informative? The award-winning Mystery Hunters, beginning its fourth season, is proving that it can.  On this week's Skepticality, Swoopy talks with David Acer—known to fans of Mystery Hunters as "Doubting Dave," the skeptical scientist who helps the junior members of his team (Araya Mengesha and Christina Broccolini) investigate paranormal mysteries. David is a close up magician, comedian, and actor and writer for children's educational programs including Popular Mechanics for Kids and Prank Patrol. David shares his thoughts about how to make debunking myths entertaining, and explains why it's difficult to get quality kids' science programs on TV in today's climate.

This week on Skepticality, science educator and skeptic Michael McRae interviews one of Australia's most recognizable scientists, Dr. Karl Kruszelnicki, who is known to most Aussies simply as "Dr. Karl." Dr. Karl is the Julius Sumner Miller Fellow at the University of Sydney, as well as a proud recipient of the Ig Nobel prize.  He is also a popular science commentator on radio and television, and a bestselling author of 26 books—including his most recent, Please Explain, which gives the facts on everything from why we yawn, to the history of near death experiences.

On this week's Skepticality, Derek talks with Dr. Phil Plait (a.k.a. "The Bad Astronomer"), Alison Smith (founder of the Skeptical Analysis of the Paranormal Society), and author Michael A. Stackpole (leader of the Arizona Skeptics) about the recent Amazing Meeting 5.5 conference on the topic of "Skepticism and Activism."

These distinguished guests also reveal details of their plans for 2008, and Phil sheds some light on possible impending "Death from the Skies",  the subject of his soon-to-be-published second book.

"Watch out for gorillas!"  "Don't trade with strangers."  "Buy this now!"  Our brains are constantly bombarded with messages about how to behave, what to buy, and whom to trust.  How do we parse these messages, and how do our choices affect the world economy?   This week on Skepticality, Derek & Swoopy discuss how economic and evolutionary theory speak the same language, and how our hardwired human biology affects modern economics, with Skeptic Society founder Dr. Michael Shermer author of The Mind of the Market: Compassionate Apes, Competitive Humans and Other Tales from Evolutionary Economics.

Skepticality welcomes 2008 with an update from the Secular Coalition for America's Lori Lipman Brown — the only lobbyist dedicated solely to the concerns of secular humanists and non-theists and to the preservation of the separation of church and state. Lori talks with Derek and Swoopy about why 2007 was the best year yet for the SCA, the top issues on the agenda for 2008, and how the current presidential candidates stack up on the issues important to skeptics.
