Each year, around the time of Charles Darwin’s birthday on February 12, the Paleontological Research Institution, also known as PRI, presents a week-long festival of events called “Darwin Days”.  The theme of this year’s celebration was “The Power of Pollination”!   

To learn more about Darwin’s observations of flowers and the insects that pollinate them, Locally Sourced Science contributor Esther Racoosin attended one of the Darwin Days events.  It was a presentation, titled “Pollination and Coevolution:  Love Story or Arms race” by Cornell Professor Anurag Agrawal.  At the beginning of today’s show, you’ll hear about Darwin’s thoughts on co-evolution and Dr. Agrawal’s research on the topic.

Later in the show, you’ll hear an interview produced by Cornell undergraduate Alejandro Schmieder.  He spoke with Cornell Assistant Professor Esther Angert about her research on a type of bacteria, Epulopiscium, that lives inside the gut of tropical surgeonfish.  Angert talks about how those two organisms have perhaps co-evolved to develop a symbiotic relationship that allows them to survive changing conditions in the ocean.

And, lastly, you’ll hear our science events calendar for the week.

In this episode, we celebrate two significant anniversaries! This month is the 3rd anniversary of Locally Sourced Science, and we celebrate it with a new music and voice introduction by Joe Lewis. We also celebrate the 30th anniversary of the famous photograph of planet Earth taken from the farthest point ever. This photo that Carl Sagan titled “The Pale Blue Dot” was taken by Voyager I on February 14, 1990.

To celebrate this anniversary, Mark Sarvary spoke with Lisa Kaltenegger, director of the Carl Sagan Institute, and with writer and director Nick Sagan, Carl Sagan’s son. Kaltenegger talks about the Voyager 1 mission, the Pale Blue Dot picture, and the Carl Sagan Institute. Nick Sagan spoke to us about the legacy of his father, who was both a scientist and a storyteller.

Sagan wrote in his “Pale Blue Dot” book: “That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. … There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world.”

This narrow-angle color image of the Earth, dubbed ‘Pale Blue Dot’, is a part of the first ever ‘portrait’ of the solar system taken by Voyager 1. The spacecraft acquired a total of 60 frames for a mosaic of the solar system from a distance of more than 4 billion miles from Earth and about 32 degrees above the ecliptic. From Voyager’s great distance Earth is a mere point of light, less than the size of a picture element even in the narrow-angle camera. Earth was a crescent only 0.12 pixel in size. Coincidentally, Earth lies right in the center of one of the scattered light rays resulting from taking the image so close to the sun. This blown-up image of the Earth was taken through three color filters — violet, blue and green — and recombined to produce the color image. The background features in the image are artifacts resulting from the magnification.

The first show of the year brought us a report from the Christmas bird count conducted by the Cayuga bird club, predictions of scientific discoveries for the new decade, and information about the Tompkins County SciHub.

Interviews: Esther Racoosin

On January 1st, 2020, about 150 volunteers ventured out to count as many local birds as possible.  The birders participated in the Christmas Bird Count sponsored by Audubon and organized locally by the Cayuga Bird Club.

To find out more, Locally-Sourced Science contributor Esther Racoosin spoke with Diane Morton, president of the Cayuga Bird club, as well as with other birders.

With the season’s chilly weather requiring people to wrap up warm, it seems like a good time to talk about fibers and fabric. In this episode, first, you’ll hear Liz Mahood present a history of the creation and production of synthetic fibers. To learn more about this intriguing science history, see the links below.

Later in the show, Esther Racoosin interviews Dr. Mike Haaf, Professor of Chemistry at Ithaca College. Dr. Haaf recently published a research article in the journal Coloration Tech. It is titled, “In situ fabric coloration with indigo synthesized in flow”. The co-authors of the paper are Ithaca College graduate Katrina Piemonte, Dr. Tyler McQuade of Virginia Commonwealth University, and Lucy Cotton and Richard Blackburn of the University of Leeds in the UK.

In his paper, Dr. Haaf  and collaborators describe a new method for synthesizing indigo dyes. The method allows for direct coloration of cotton fabrics without using a typical vat dyeing process that is used in the garment industry to dye denim jeans.

Finally, we hear Meaghan McElroy present the science events calendar for the week.
