Big Picture Science for Aug 12, 2019 - Granting Immunity













Big Picture Science - Granting Immunity

“Diversity or die” could be your new health mantra. Don’t boost your immune system, cultivate it! Like a garden, your body’s defenses benefit from species diversity.  Find out why multiple strains of microbes, engaged in a delicate ballet with your T-cells, join internal fungi in combatting disease. Plus, global
ecosystems also depend on the diversity of its tiniest members; so what happens when the world’s insects bug out?

Big Picture Science for Aug 05, 2019 - Sci-Fi From the Future












(Repeat)  Are you ready to defer all your personal decision-making to machines?  Polls show that most Americans are uneasy about the unchecked growth of artificial intelligence. The possible misuse of genetic engineering also makes us anxious. We all have a stake in the responsible development of science and technology, but fortunately, science fiction films can help.

The movies Ex Machina and Jurassic Park suggest where A.I. and unfettered gene-tinkering could lead. But even less popular sci-fi movies can help us imagine unsettling scenarios regarding over-population, smart drugs, and human cloning.

And not all tales are grim.  The 1951 film, The Man in the White Suit, weaves a humorous story of materials science run amok.

So, grab a bowl of popcorn and join us in contemplating the future of humanity as Hollywood sees it!

Guest:
Andrew Maynard – Physicist and professor at the School for the Future of Innovation in Society at Arizona State University.  Author of Films from the Future: The Technology and Morality of Sci-Fi Movies.

Big Picture Science for July 29, 2019 - Skeptic Check: Flat Earth


Sorry for the late posting. Life and things you know.











Big Picture Science - Skeptic Check: Flat Earth

(Repeat) The Earth is not round.  Technically, it’s an oblate spheroid.  But for some people, the first statement is not even approximately correct.  Flat Earthers believe that our planet resembles – not a slightly squashed grapefruit – but a thick pancake.   A journalist who covered a Flat Earth convention describes the rationale behind this ever-more popular belief.

So how do you establish science truth?  We look at the difference between a truly scientific examination of extraordinary claims and approaches that feel and look science-y but aren’t.

Find out how one man will use telescopes and balloons in the desert to demonstrate that the Earth is a globe, while a biologist runs a test on the waters of Loch Ness to see if it contains prehistoric reptile DNA.

And what happens when amateur investigators chase ghosts, UFOs, and Bigfoot with science instruments, but without an understanding of the scientific method.
