Battling Bacteria 2019-10-07 07:33:27 We can't say we weren't warned. More than 75 years ago, bacteriologist Rene Dubos cautioned that misuse of antibiotics could breed drug-resistant bacteria - and he has been proved prescient. In this episode: the rise of superbugs, why we ignored the warnings about them, how some are enlisting an old therapy to fight back, and whether we'll heed history's lessons in the face of a future pandemic. Plus, a weird unforeseen effect of antibiotics being investigated at the Body Farm. Guests:

Headed For Trouble 2019-09-30 08:47:12 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? Guests:
James Grant Peterkin - Tour guide, resident, and British Honorary Consul on Easter Island

For Good Measure 2019-09-09 07:53:48 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 gravitational wave detectors able to measure spacetime distortions to 1/1000th the width of a proton - is something fundamental lost along the way? Meanwhile, the BiPiSci team accepts the banana-measurement challenge. Guests:
Jon Pratt - Mechanical engineer and engineer and Chief of the Quantum Measurement Division of the Physical Measurement Laboratory (PML) at the National Institute of Standards and Technology
Wolfgang Ketterle - Physicist at MIT, Nobel Laureate

Skeptic Check: Data Bias 2019-09-02 09:00:00 Sexist snow plowing? Data that guide everything from snow removal schedules to heart research often fail to consider gender. In these cases, "reference man" stands in for "average human." Human bias also infects artificial intelligence, with speech recognition triggered only by male voices and facial recognition that can't see black faces. We question the assumptions baked into these numbers and algorithms. Guests:
Caroline Criado-Perez - Journalist and author of "Invisible Women: Data Bias in a World Designed for Men"
Kade Crockford - Director of the Technology for Liberty Program at the ACLU of Massachusetts
Amy Webb - Futurist, founder and CEO of the Future Today Institute, and author of "The Big Nine: How the Tech Titans and There Thinking Machines Could Warp Humanity" 51 minutes, 22 seconds
Granting Immunity 2019-08-12 07:44:53 "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? Guests:

Let's Stick Together 2019-07-22 08:56:11 Crowded subway driving you crazy? Sick of the marathon-length grocery store line? Wish you had a hovercraft to float over traffic? If you are itching to hightail it to an isolated cabin in the woods, remember, we evolved to be together. Humans are not only social, we're driven to care for one another, even those outside our immediate family. We look at some of the reasons why this is so - from the increase in valuable communication within social groups to the power of the hormone oxytocin. Plus, how our willingness to tolerate anonymity, a condition which allows societies to grow, has a parallel in ant supercolonies. Guests:
Adam Rutherford - Geneticist and author of "Humanimal: How Homo sapiensBecame Nature's Most Paradoxical Creature - a New Evolutionary History"

Math's Paths 2019-07-15 06:42:47 If you bake, you can appreciate math's transformative properties. Admiring the stackable potato chip is to admire a hyperbolic sheet. Find out why there's no need to fear math - you just need to think outside the cuboid. Also, how nature's geometric shapes inspire the next generation of squishy robots and an argument for radically overhauling math class. The end point of these common factors is acute show that's as fun as eating Pi. Guests:

Nailing the Moon Landing 2019-07-01 08:36:21 Neil, Buzz, and Michael made it look effortless, but the moon landing was neither easy nor inevitable. Soon after President Kennedy publicly stated the goal of sending Americans to the moon, NASA confessed that the chances of success were only about 50/50. But on July 20, 1969, despite enormous difficulties, astronauts stepped onto the lunar regolith. In this special anniversary episode, we go behind the iconic phrases and familiar photos to consider the errors, mishaps, and the Plan B contingencies that dogged the project, as well as hear of the hundreds of thousands of men and women who made Apollo 11 possible.

Risk Why do we revere risk-takers, even when their actions terrify us? Why are some better at taking risks than others? This hour, TED speakers explore the alluring, dangerous, and calculated sides of risk. Guests include professional rock climber Alex Honnold, economist Mariana Mazzucato, psychology researcher Kashfia Rahman, structural engineer and bridge designer Ian Firth, and risk intelligence expert Dylan Evans.
#540 Specialize? Or Generalize? Ever been called a "jack of all trades, master of none"? The world loves to elevate specialists, people who drill deep into a single topic. Those people are great. But there's a place for generalists too, argues David Epstein. Jacks of all trades are often more successful than specialists. And he's got science to back it up. We talk with Epstein about his latest book, "Range: Why Generalists Triumph in a Specialized World".
