• Eureka!

    ENCORE From the double-helix to the expansion of the universe, great scientific discoveries reshape our understanding of who we are and how things work. But great discoveries require more than just a great mind. We tour brainy breakthroughs from Archimedes to Darwin, and find out what made their revolutionary insights possible.

    Also, why you need more than a stratospheric I.Q. to be a super-achiever. And how the invention of reading re-directed the course of civilization and re-wired our brains in the process.

  • 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.

  • 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.
