Big Picture Science for Mar 29 - Skeptic Check: Useful Delusions







Big Picture Science - Skeptic Check: Useful Delusions

Can self-deception be useful? During the pandemic, it has been fashionable to say that we’re “following the science,” and that our behavior is determined by verifiable facts. We are, after all, self-declared rational beings, and that’s clearly useful in guiding our reaction to a pandemic. It’s true that fear and suspicion have caused some to make contrary choices such as declining vaccines, but that behavior is considered irrational. But are there situations when delusional thinking can help you thrive? Why are we not as rational as we think?

Guests:

  • Steven Novella – Neurologist and professor at Yale University School of Medicine. Host of the Skeptics Guide to the Universe podcast.
  • Shankar Vedantam – Host of the Hidden Brain podcast and radio show, and co-author of “Useful Delusions: The Power & Paradox of the Self-Deceiving Brain.”

Big Picture Science for Mar 22 - Neanderthal in the Family







Big Picture Science - Neanderthal in the Family

Back off, you Neanderthal! It sounds as if you’ve just been dissed, but maybe you should take it as a compliment. Contrary to common cliches, our Pleistocene relatives were clever, curious, and technologically inventive. Find out how our assessment of Neanderthals has undergone a radical rethinking, and hear about the influence they have as they live on in our DNA. For example, some of their genes have a strong association with severe Covid 19 infection. Plus, how Neanderthal mini-brains grown in a lab will teach us about the evolution of Homo sapiens.

Guests:

  • Svante Pääbo – Evolutionary geneticist and Director of the Max Planck Institute for Evolutionary Anthropology.
  • Doyle Stevick – Associate professor of educational leadership and policies at the University of South Carolina.
  • Beverly Brown – Professor emerita of anthropology, Rockland Community College, New York.

Big Picture Science for Mar 15 - DecodeHer







Big Picture Science - DecodeHer

They were pioneers in their fields, yet their names are scarcely known – because they didn’t have a Y chromosome.  We examine the accomplishments of two women who pioneered code breaking and astronomy during the early years of the twentieth century and did so in the face of social opprobrium and a frequently hostile work environment.

Henrietta Leavitt measured the brightnesses of thousands of stars and discovered a way to gauge the distances to galaxies, a development that soon led to the concept of the Big Bang.

Elizabeth Friedman, originally hired to test whether William Shakespeare really wrote his plays, was soon establishing the science of code breaking, essential to success in the two world wars.

Also, the tech industry is overwhelmingly male. Girls Who Code is an initiative to redress the balance by introducing girls to computer programming, and encouraging them to follow careers in tech.

Big Picture Science for Feb 22 - Creature Discomforts






 

Big Picture Science - Creature Discomforts

(REPEAT) - Okay you animals, line up: stoned sloths, playful pandas, baleful bovines, and vile vultures. We’ve got you guys pegged, thanks to central casting.

Or do we? Our often simplistic view of animals ignores their remarkable adaptive abilities. Stumbly sloths are in fact remarkably agile and a vulture’s tricks for thermoregulation can’t be found in an outdoors store.

Our ignorance about some animals can even lead to their suffering and to seemingly intractable problems. The South American nutria was brought to Louisiana to supply the fur market. But the species got loose and tens of millions of these rodents are destroying the environment. It literally has a bounty on its tail.

Hear about research that corrects a menagerie of misunderstandings about our fellow furry, feathered, and scaly animals, and how getting over ourselves to know them better can have practical benefits. Will you still recoil from termites if you learn that they are relevant to the future of robots, global warming, and smart design?

Big Picture Science for Feb .15 - Granting Immunity







Big Picture Science - Granting Immunity

(REPEAT) “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 Feb .01 - Iron, Coal, WoodBig Picture Science for Feb .01 - Iron, Coal, Wood







Big Picture Science - Iron, Coal, Wood

Maybe you don’t remember the days of the earliest coal-fired stoves. They changed domestic life, and that changed society. We take you back to that era, and to millennia prior when iron was first smelt, and even earlier, when axe-handles were first fashioned from wood, as we explore how three essential materials profoundly transformed society.

We were once excited about coal’s promise to provide cheap energy, and how iron would lead to indestructible bridges, ships, and buildings. But they also caused some unintended problems: destruction of forests, greenhouse gases and corrosion. Did we foresee where the use of wood, coal, and iron would lead? What lessons do they offer for our future?

Big Picture Science for Jan. 04, Headed For Trouble







Big Picture Science - Headed For Trouble

The stone heads on Easter Island are an enduring mystery: why were they built and why were they abandoned and destroyed? The old ideas about cultural collapse are yielding to new ones based on careful investigation on the ground - but also from above. What surprising explanations have we found and are we off base to think that ancient societies such as the Easter Islanders or the classical Egyptians were, in the end, failures? Can what we learn from these histories help predict which societies will survive?

Big Picture Science for Dec. 28, For Good Measure






 

Big Picture Science - For Good Measure
 

(Repeat) The reign of Le Grand K has come to an end. After 130 years, this hunk of metal sitting in a Parisian vault will no longer define the kilogram. The new kilogram mass will be defined by Planck’s constant, joining three other units for redefinition by fundamental constants.  But as we measure with increasing
precision – from cesium atomic clocks to gravity waves 1000th the width of a proton – is something fundamental lost along the way?  Meanwhile, the BiPiSci team accepts the banana-measurement challenge.
