Introducing: Unsung Science with David Pogue

Mosquitoes are the deadliest creatures on earth; they kill 500,000 people a year—and as the planet warms, more species are spreading North from the tropics. In 2013, a nasty new type, called Aedes Aegypti, arrived in Fresno, California. But traditional tactics, like spraying insecticide and genetic modification, have ugly side effects. So one genius programmer from Google thought up a better solution—that doesn’t involve insecticide; doesn’t mess around with genes; doesn’t require irradiating; makes it impossible for the mosquitoes to develop resistance; can’t affect any other species; and costs less than what governments spend now on treating their citizens for Dengue fever. A lot was at stake in the Fresno experiment; if it worked, the technique could save lives around the world. (Spoiler: It worked.)
Guests: Linus Upson, VP of Engineering at Verily. Leslie Vosshall, professor of neuroscience at Rockefeller University. Jodi Holeman, Fresno Consolidated Mosquito Abatement District. Peter Massaro, Google director of automation. Jacob Crawford, senior scientist, Verily.

What Happened to the Mosquitoes in Fresno?

It may seem as though we got the Pfizer and Moderna COVID vaccines incredibly quickly. But Hungarian biochemist Katalin Karikó had been trying to make mRNA vaccines work for 30 years while fighting scientific gatekeepers who thought her idea was absurd. Her grants were denied, her papers rejected, her speaking invitations withdrawn; eventually, the University of Pennsylvania demoted her. But she still refused to quit, and in 2005, she and collaborator Drew Weissman cracked the code. They figured out how mRNA could direct our own cells to manufacture medicines to order. Their breakthrough saved the world from the worst of the pandemic—and opened a new world of medicines and vaccines for a huge range of diseases.
Guests: Katalin Karikó, senior VP at BioNTech. Drew Weissman, Perelman School of Medicine, U Penn. Derek Rossi, co-founder of Moderna.

How We Almost Blew the Vaccine

The media is plenty freaked out about “deepfakes”: Computer-generated videos of famous people saying things they never actually said. But only the video is faked; the audio parts, the voices of those fake celebrities, were supplied by human impersonators. But now, software exists to mimic anyone’s voice, opening a Pandora’s Box of fraud, deception, and what one expert calls “the end of trust.” Fortunately, a new coalition of 60 news organizations and software companies think they have a way to shut down the nightmare before it begins.
Guests: Ragavan Thurairatnam, Dessa. Nina Schick, author and deepfakes expert. Joan Donavan, Harvard Kennedy School. Charlie Choi, CEO of Lovo. Dana Rao, chief counsel, Adobe.

Audio Deepfakes and the End of Trust

Tornadoes are nasty and dangerous. They appear and disappear so fast, there’s usually no time for evacuation—and the United States gets 75% of all the world’s tornadoes, about 1,300 of them a year. They occur all year ‘round, in all 50 states, but the biggest swarm forms in Tornado Alley, in the southern Plains states like Texas, Oklahoma, Kansas, and Nebraska. In 2018, storm chaser and meteorologist Victor Gensini made a startling discovery: Tornado Alley has been shifting eastward. Their growing frequency in Mississippi, Alabama, and Tennessee is a deadly development, because more people live in these areas, often in flimsy housing. And because there are more trees and buildings, it's much harder to see the devastation coming.
Guest: Victor Gensini, storm chaser and meteorology professor at Northern Illinois University.

Tornado Alley is Shifting Eastward—and We're Not Ready

Perseverance, NASA's latest Mars rover, is a one-ton, $2 billion marvel. The plan was for it to enter the Mars atmosphere going 12,000 miles an hour. The problem: How do you slow it down enough to set it down gently on the surface? You can't use retro rockets, because they'd stir up so much dust, the rover’s cameras and instruments would be ruined. You can’t deliver Perseverance inside a larger spaceship, because the rover wouldn’t be able to drive out of the landing crater. You can’t even control the descent from Earth, because it takes so long for our signals to reach Mars; by the time the rover received a course-correction instruction, there’d be nothing left of it but a smoking wreck. Yet NASA pulled it off—with a nutty, Rube Goldberg-y, multi-stage, seven-minute-long, completely automated system involving a parachute, an airborne launch platform, and a cable.
Guest: Alan Chen, NASA Entry, Descent, and Landing Lead for the Mars 2020 mission.

How NASA's $2 Billion Rover Landed Itself on Mars: "Seven Minutes of Terror"

The first time you heard “Star Trek” characters speak Klingon, or the “Game of Thrones” characters speaking Dothraki and High Valyrian, you might have assumed that the actors were just speaking a few words of gibberish, created by some screenwriter to sound authentic. But these are complete languages, with vocabulary, syntax, grammar, and even made-up histories. There’s only one person on the planet whose full-time job is creating them—and these days, he’s swamped with requests. No doubt about it: Conlangs (constructed languages) are the new special effect. Me nem nesa!
Guests: David Peterson, author/linguist/full-time language maker. Mark Okrand, author/linguist/creator of Klingon. Angela Carpenter, linguistics professor at Wellesley College.

Who Makes the Fake Languages for Hollywood?

It's Thanksgiving weekend, and for many podcasts, a week off. But we didn't want to sock you with some re-run—or, worse, leave you with no episode at all. So David Pogue is here to offer a free chapter from his audio book, "How to Prepare for Climate Change." You'll hear the complete Introduction, which is designed to teach you the difference between mitigation and adaptation—and convince you to keep doing the former, but start doing the latter.

How to Prepare for Climate Change: Intro

Your smartphone can see, hear, and speak—even if you can’t. So it occurred to the engineers at Apple and Microsoft: Can the phone be a talking companion for anyone with low vision, describing what it’s seeing in the world around you?
Today, it can. Thanks to some heavy doses of machine learning and augmented reality, these companies’ apps can identify things, scenes, money, colors, text, and even people (“30-year-old man with brown hair, smiling, holding a laptop—probably Stuart”)—and then speak, in words, what’s in front of you, in a photo or in the real world. In this episode, the creators of these astonishing features reveal how they turned the smartphone into a professional personal describer—and why they care so deeply about making it all work.
Guests: Satya Nadella, Microsoft CEO. Saqib Shaikh, project lead for Microsoft’s Seeing AI app. Jenny Lay-Flurrie, Chief Accessibility Officer, Microsoft. Ryan Dour, accessibility engineer, Apple. Chris Fleizach, Mobile Accessibility Engineering Lead, Apple. Sarah Herrlinger, Senior Director of Global Accessibility, Apple.

How Apple and Microsoft Built the Seeing-Eye Phone

In the early 1970s, “mobile phones” were car phones: Permanently installed monstrosities that filled up your trunk with boxes and, in a given city, could handle only 20 calls at a time. Nobody imagined that there’d be a market for handheld, pocketable cellphones; the big phone companies thought the idea was idiotic. But Marty Cooper, now 92, saw a different future for cellular technology—and he had 90 days to make it work. A story of corporate rivalry, Presidential interference…and unquenchable optimism.
Guests: Marty Cooper, father of the cellphone. Arlene Cooper, technology entrepreneur.
