It's In Material [rebroadcast]

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?

Skeptic Check: Pandemic Fear

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.  Guests: <ul> <li><a href="https://www.jasonfagone.com/">Jason Fagone</a> – Author of “<a href= "https://www.amazon.com/gp/product/B01M0EOI6I/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B01M0EOI6I&linkCode=as2&tag=arweal-20&linkId=8caf08d9ae14924635bc183cb06079b1">The Woman Who Smashed Codes: A True Story of Love, Spies, and the Unlikely Heroine Who Outwitted America’s Enemies</a>”</li> <li><a href="http://laurengunderson.com/">Lauren Gunderson</a> – Playwright of Silent Sky, which is being performed all over the world, form the <a href="https://firstfolio.org/">First Folio Theatre</a> to the <a href= "http://www.repertoryphilippines.ph/">Repertory Philippines</a></li> <li><a href="https://girlswhocode.com/our-team/">Reshma Saujani</a> – Founder and CEO of Girls Who Code, and the author of "<a href= "https://www.amazon.com/gp/product/1524762334/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=1524762334&linkCode=as2&tag=arweal-20&linkId=97b1daba4b4e53a009a914f297138c42">Brave, Not Perfect: Fear Less, Fail More, and Live Bolder</a>”</li> </ul>

It’s one of the most bizarre biological experiments ever. In the 18th century, a scientist fitted a pair of tailor-made briefs on a male frog to determine the animal’s contribution to reproduction.  The process of gestation was a mystery and scientists had some odd-ball theories.   Today, a 5th grader can tell you how babies are made, but we still don’t know exactly what life is.  In our quest to understand, we’re still at the frogs’ pants stage. Find out why conception took centuries to figure out.  Also, why the 1970s Viking experiments, specifically designed to detect life on Mars, couldn’t give us a definitive answer.  Plus, can knowing where life isn’t help define what it is?  Take a tour of the world’s barren places.  Guests: <ul> <li><a href= "https://www.spacefest.info/IV/About/Jay.html">Jay Gallentine</a> - Author of books about space and space history.</li> <li><a href="http://edwarddolnick.net/">Edward Dolnick</a> - Author and former science writer at the Boston Globe.  His book is <a href= "https://www.amazon.com/gp/product/0465082955/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0465082955&linkCode=as2&tag=arweal-20&linkId=0f54a6dd39f6c5bbbeb80e67beb13ea0">The Seeds of Life: From Aristotle to Da Vinci, from Shark’s Teeth to Frogs’ Pants</a>.</li> <li><a href= "https://spacescience.arc.nasa.gov/staff/chris-mckay">Chris McKay</a> - Planetary scientist, NASA Ames Research Center. </li> </ul> Originally aired July 10, 2017

Climate change isn’t happening.  Vaccines make you sick.  When it comes to threats to public or environmental health, a surprisingly large fraction of the population still denies the consensus of scientific evidence.  But it’s not the first time – many people long resisted the evidentiary link between HIV and AIDS and smoking with lung cancer. There’s a sense that science denialism is on the rise.  It prompted a gathering of scientists and historians in New York City to discuss the problem, which included a debate on the usefulness of the word “denial” itself.  Big Picture Science was there. We report from the Science Denial symposium held jointly by the New York Academy of Sciences and Rutgers Global Health Institute.  Find out why so many people dig in their heels and distrust scientific findings.  Plus, the techniques wielded by special interest groups to dispute some inconvenient truths.  We also hear how simply stating more facts may be the wrong approach to combating scientific resistance.

But wait a minute – we don’t always relate to other humans.  Our behavior can be impulsive and even self-sabotaging – our emotions are often conflicted and irrational.   We cry when we’re happy.  Frown when we’re pensive.  A suite of factors, much of them out of our control, govern how we behave, from genes to hormones to childhood experience.  One study says that all it takes for a defendant to receive a harsher sentence is a reduction in the presiding judge’s blood sugar.

Your Brain's Reins [rebroadcast]

Do we still need doctors?  There are umpteen alternative sources of medical advice, including endless and heartfelt health tips from people without medical degrees. Frankly, self-diagnosis with a health app is easier and cheaper than a trip to a clinic.   Since we’re urged to be our own health advocate and seek second opinions, why not ask Alexa or consult with a celebrity about what ails us? Find out if you can trust these alternative medical advice platforms.  Plus, lessons from an AIDS fighter about ignoring the findings of medical science.   And, if AI can diagnose better than an MD, will we stop listening to doctors altogether? It’s our monthly look at critical thinking … but don’t take our word for it!

Handling the Holidays

Why create more landfill?  Perhaps you should resist the urge to toss those old sneakers, the broken ceiling fan, or last year’s smart phone.  Instead, repurpose them!  Global junk entrepreneurs are leading the way in turning trash to treasure, while right-to-repair advocates fight for legislation that would give you a decent shot at fixing your own electronic devices.  And, if you toss food scraps down the drain as you cook, are you contributing to a “fatberg” horror in the sewer?

Waste Not

(repeat) We all may retreat to our protective shells, but evolution has perfected the calcite variety to give some critters permanent defense against predators.  So why did squids and octopuses lose their shells?  Find out what these cephalopods gained by giving up the shell game. Plus why Chesapeake Bay oyster shells are shells of their former selves.  What explains the absence of the dinner-plate sized oysters of 500,000 years ago, and how conservation paleobiology is probing deep time for strategies to bring back these monster mollusks. Also, was the Earth once encased in a giant, continental shell?  A new theory of plate tectonics.  Land ho!
