Summary
Written by a model from the transcript; not yet reviewed.
This milestone episode celebrates the fiftieth anniversary of the Committee for Skeptical Inquiry live from Buffalo. The hosts and guest Richard Wiseman discuss the realities of the skeptical movement, space exploration missions, and invasive insect tracking. Segments also cover human echolocation studies, the psychological risks of clean eating trends, cosmic engineering ideas like Dyson spheres, and climate change mitigation with guest Michael Mann.
- Regularly check trees in the fall and scrape off spotted lanternfly egg masses to limit their invasive spread. 18:39
- Visually impaired individuals can train themselves to use tongue clicks for surprisingly accurate spatial echolocation. 22:58
- Prioritize a balanced, risk-beneficial relationship with food rather than falling for restrictive clean eating dogmas. 30:47
- Global warming essentially pauses when carbon emissions finally reach zero, making decarbonization the primary climate goal. 1:00:18

Highlights
- 6:05
Punching Above Our Weightinsight
The hosts and Richard Wiseman discuss the impact of the skeptical movement. They reflect on how a small, scrappy group punches above its weight in the media and culture.
- 9:10
Jay explains that NASA retooled Artemis III into a low Earth orbit test mission to evaluate lunar landers built by SpaceX and Blue Origin.
- 18:39
Spotted Lanternfly Invasionstrategy
The panel discusses the destructive spotted lanternfly and how citizens are encouraged to crush the bugs and scrape away their egg masses.
- 24:09
Echolocation in Blind Expertsinsight
George outlines a study showing that blind individuals using clicks can successfully locate virtual objects by repurposing their visual cortex.
- 45:20
Dyson Swarms on Small Starsinsight
Bob explains why advanced civilizations might build Dyson swarms around tiny red dwarfs or white dwarfs instead of sun-like stars.
- 55:43
Evolution of Biological Sexdata
Steve explains that the emergence of sexual reproduction and genetic recombination drove a massive explosion of morphological diversity.
- 1:00:18
Global Warming Flat Lineinsight
Michael Mann explains that planetary warming stops as soon as carbon pollution emissions are completely brought to zero.
Quotes
“Those things will never come back now, because we've pretty much eradicated pseudoscience.”
Unnamed speaker · 4:56 “The four experts got way better than chance, and three out of the four, who were blindest earlier in their lives, were 70% right, in terms of locating the items.”
Unnamed speaker · 25:04 “If you have celiac disease, your calculus is different.”
Cara Santa Maria · 36:35 “Artemis III was supposed to be the moon landing.”
Unnamed speaker · 8:56 “A red dwarf, you could think of it as a huge fusion reactor that just doesn't turn off.”
Bob Novella · 50:45 “The study is talking about looking for Dyson swarms around tiny, long‑lived stars like a red dwarf or a white dwarf.”
Bob Novella · 51:04 “So, the takeaway from this study is that Dyson spheres aren't necessarily more likely.”
Bob Novella · 53:19 “The best science at that time indicated that the so‑called thermal inertia of the oceans would dominate, the oceans would continue to warm up, sort of like, you know, if you slam the brakes on a locomotive, it doesn't come to an immediate halt.”
Unnamed speaker · 1:00:28 “The only way we do that is by getting policymakers who will favor the changes in the system.”
Unnamed speaker · 1:29:26 “Hydroelectric power was first produced by nearby Niagara Falls in 1934 and has since been the source of greater than 80% of electrical power in Buffalo.”
