Big Picture Science for May 25, Gained in Translation













Big Picture Science - Gained in Translation

(Repeat) Your virtual assistant is not without a sense of humor. Its repertoire includes the classic story involving a chicken and a road.  But will Alexa laugh at your jokes? Will she groan at your puns?

Telling jokes is one thing. Teaching a computer to recognize humor is another, because a clear definition of humor is lacking. But doing so is a step toward making more natural interactions with A.I.

Find out what’s involved in tickling A.I.’s funny bone. Also, an interstellar communication challenge: Despite debate about the wisdom of transmitting messages to space, one group sends radio signals to E.T. anyway. Find out how they crafted a non-verbal message and what it contained.

Plus, why using nuanced language to connive and scheme ultimately turned us into a more peaceful species. And yes, it’s all gouda: why melted cheese may be the cosmic message of peace we need.

Big Picture Science for May 18, Vaccine, When?













Big Picture Science - Vaccine, When?

It will be the shot heard ‘round the world, once it comes.  But exactly when can we expect a COVID vaccine?  We discuss timelines, how it would work, who’s involved, and the role of human challenge trials.

Also, although he doesn’t consider himself brave, we do.  Meet a Seattle volunteer enrolled in the first coronavirus vaccine trial.  And, while we mount an elaborate defense against a formidable foe, scientists ask a surprising question: is a virus even alive?

Guests:
  • Nigel Brown – Emeritus Professor of Molecular Microbiology at the University of Edinburgh
  • Ian Haydon – Public information specialist at the University of Washington, Seattle
  • Bonnie Maldonado – Professor of Pediatrics and Infectious Diseases at the Stanford University School of Medicine

Big Picture Science for May 11, To the Bat Cave













Big Picture Science - To the Bat Cave

To fight a pandemic, you need to first understand where a virus comes from. That quest takes disease ecologist Jon Epstein to gloomy caverns where bats hang out. There he checks up on hundreds of the animals as his team from the EcoHealth Alliance trace the origins of disease-causing viruses. But their important work is facing its own threat; the Trump administration recently terminated funding to the Alliance because of its collaboration with Chinese scientists.

Hear how Dr. Epstein finds the viruses, what kind of human activity triggers outbreaks, and how science counters the unsubstantiated claim that the virus escaped from a lab.

Big Picture Science for May 04, Is Life Inevitable?













Big Picture Science - Is Life Inevitable?

(Repeat) A new theory about life’s origins updates Darwin’s warm little pond.  Scientists say they’ve created the building blocks of biology in steaming hot springs. Meanwhile, we visit a NASA lab where scientists simulate deep-sea vent chemistry to produce the type of environment that might spawn life.  Which site is best suited for producing biology from chemistry?

Find out how the conditions of the early Earth were different from today, how meteors seeded Earth with organics, and a provocative idea that life arose as an inevitable consequence of matter shape-shifting to dissipate heat. Could physics be the driving force behind life’s emergence?

Guests:
  • Caleb Scharf – Director of Astrobiology at Columbia University, New York
  • Laurie Barge – Research scientist in astrobiology at NASA’s Jet Propulsion Laboratory

Big Picture Science for Apr 27, Skeptic Check: Covid Conspiracy













Big Picture Science - Skeptic Check: Covid Conspiracy

Nature abhors a vacuum, but conspiracy theorists love one. While we wait for scientists to nail down the how and why of the coronavirus, opportunists have jumped into the void, peddling DIY testing kits and fake COVID cures like colloidal silver. They’ve even cooked up full-blown conspiracy theories about a lab-grown virus. Find out why this crisis has dished up more than the usual share of misinformation and hucksterism, and how these interfere with our ability to navigate it safely.

Guests:
  • Whitney Phillips - Professor of communication and rhetorical studies at Syracuse University, and author of three books, most recently You Are Here: A Field Guide for Navigating Polluted Information
  • Joan Donovan - Research director at Harvard’s Shorenstein Center on Media, Politics and Public Policy

Big Picture Science for Apr 20, Treating the Virus













Big Picture Science - Treating the Virus

It’s not like waiting for Godot, because he never arrived.  A coronavirus vaccine will come.  But it is still months away.  Meanwhile, scientists are adding other weapons to our growing arsenal against this virus. The development of antibody tests, antibody cures, and antivirals offer hope that we can soon have the tools to battle those who’ve been sickened by the COVID-19 virus while we wait for the inoculation that will prevent it.

Guests:
  • Deepta Bhattacharya – Immunologist at the University of Arizona whose lab is making a coronavirus antibody test.
  • Mark Denison – Professor of pathology, microbiology, and immunology, Vanderbilt University School of Medicine

Big Picture Science for Apr 13, The Other Living World













Big Picture Science - The Other Living World

Reason for hope is just one thing that ecologist Carl Safina can offer.  He understands why many of us turn to nature to find solace during this stressful time. Safina studies the challenges facing the ultimate survival of many species, but also gives a portrait of animals from their point of view. He describes how diverse animals such as sperm whales, bear cubs, macaws, and chickens deal with uncertainty, and assert their quirky individuality while learning to become part of a community. So is it possible for us to reconnect not just with humanity, but also with the other living world?

Big Picture Science for Apr 06, Zombies, Bigfoot, and Max Brooks













Big Picture Science - Zombies, Bigfoot, and Max Brooks

What do a zombie attack and a viral pandemic have in common?  They are both frightening, mindless, and relentless in their assault.  And both require preparedness.   That’s why the author of “World War Z” – a story about a battle against zombies – lectures at West Point.

Max Brooks has also recorded a public service announcement with his celebrated father, Mel Brooks, touting the importance of social distancing during the coronavirus pandemic.  His newest novel portrays a different assailant: Bigfoot.

Whether our enemy is the undead, a hirsute forest dweller, or an invisible virus, panic won’t help us survive.  Find out what will.

Big Picture Science for Mar 30, Let’s Take a Paws













Big Picture Science - Let’s Take a Paws

Humans aren’t the only animals stressed-out by social distancing.  Narwhals send out echolocation clicks to locate their buddies and ease their loneliness.  And a plant about to be chomped by a caterpillar knows that the world can be a scary place.

In this episode, from dogs to narwhals to plants, we put aside human-centric stories to find out how other living creatures map their world, deal with stress, and communicate.

Big Picture Science for Mar 23, How Bad Does It Have to Get?













Big Picture Science - How Bad Does It Have to Get?

“Climate change at warp speed” is the way one scientist described the coronavirus outbreak.

In a show recorded before a live audience at the Seattle AAAS meeting, and co-presented with the BBC World Service, we discuss out how politics and psychology lead people to tune out inconvenient scientific findings even when the stakes are high – as well as what we can do about it.

Big Picture Science for Mar 16, It's In Material












Big Picture Science - It's In Material

Repeat - Astronauts are made of the “right stuff,” but what about their spacesuits?   NASA’s pressurized and helmeted onesies are remarkable, but they need updating if we’re to boldly go into deep space.   Suiting up on Mars requires more manual flexibility, for example.  Find out what innovative materials might be used to reboot the suit.

Meanwhile, strange new materials are in the pipeline for use on terra firma: spider silk is kicking off the development of biological materials that are inspiring ultra-strong, economical, and entirely new fabrics.  And, while flesh-eating bacteria may seem like an unlikely ally in materials science, your doctor might reach for them one day.  The bacterium’s proteins are the inspiration for a medical molecular superglue.

Plus, an overview of more innovative materials to come, from those that are 3D printed to self-healing concrete.

Big Picture Science for Mar 09, Skeptic Check: Pandemic Fear












Big Picture Science - Skeptic Check: Pandemic Fear

Contagion aside, coronavirus is a powerful little virus.  It has prompted a global experiment in behavior modification: elbow bumps instead of handshakes, hand sanitizer and mask shortages, a gyrating stock market.

Pragmatism motivates our behavior toward the spread of this virus, but so do fear and panic. In 1918, amplified fear made the Spanish Flu pandemic more deadly.

Can we identify when we’re acting sensibly in the face of COVID-19, or when fear has hijacked our ability to think rationally and protect ourselves?

Big Picture Science for Mar 02, DecodeHer













Big Picture Science - DecodeHer

(Repeat) 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 17, Climate Changed













Big Picture Science - Climate Changed

Have you adapted to the changing climate? Rising waters, more destructive wildfires, record-breaking heatwaves. Scientists have long predicted these events, but reporting on climate change has moved from prediction to description. There’s no time for dwelling on “we should haves.” Communities and organizations are being forced to adapt. Find out what that means, the role of the new “resilience officers,” and the unique response of Native American cultures. Plus, is the coronavirus outbreak made worse by climate change?

Guests:
  • James Randerson – Professor of Earth Science, University of California, Irvine
  • Victor Rodriguez – PhD student, Carnegie Mellon University, Department of Engineering and Public Policy
