<link>http://www.northcountrypublicradio.org/news/story/20854/20121108/natural-selections-why-is-the-sky-blue-take-2</link>
<description><![CDATA[ (Nov 8, 2012) Dr. Curt Stager tries once again to answer the classic child&apos;s question. It is a poser that was worthy of Einstein&apos;s time, who eventually came up with the best answer. But it&apos;s complicated. And when the sky isn&apos;t blue, why not? What&apos;s up with that? Martha Foley wants to know. [<strong><a href="http://www.northcountrypublicradio.org/news/story/20854/20121108/natural-selections-why-is-the-sky-blue-take-2">full story</a></strong>]]]></description>

<title>Natural Selections: Fallout and carbon dating</title>
<link>http://www.northcountrypublicradio.org/news/story/14235/20120705/natural-selections-fallout-and-carbon-dating</link>
<description><![CDATA[ (Jul 5, 2012) Curt Stager and Martha Foley discuss radiocarbon dating. Fallout from atmospheric testing of nuclear weapons has distorted the background levels of the radioactive isotope carbon-14, used by archaeologists to date organic materials. But it has an upside, providing a new scale by which to date more recent events, helping researchers track cell turnover in different parts of the body and in testing the age of everything from vintage wine to elephant ivory.

<title>Natural Selections: Atom supply</title>

<description><![CDATA[ (Feb 23, 2012) In Song of Myself, Whitman says, &quot;For every atom belonging to me as good belongs to you.&quot; Given that the world atom supply is finite, more or less, Martha Foley and Dr. Curt Stager explore the notion that all of us are made up of some atoms that were found in William Shakepeare, the dinosaurs, and each other.

<description><![CDATA[ (Sep 15, 2011) Martha Foley poses the classic child&apos;s question. According to Dr. Curt Stager, the answer lies in the composition of the atmosphere, and in the refractive qualities of different wavelengths of light.

<description><![CDATA[ (Oct 28, 2010) The notion that all colors mixed together make white can be disputed by any child who has made a stew of his paint set, but that is what a prism shows us. Dr. Curt Stager and Martha Foley talk about colors, and how they differ to different eyes.

<title>Solstice, planets and more in the night sky</title>
<link>http://www.northcountrypublicradio.org/news/story/15818/20100615/solstice-planets-and-more-in-the-night-sky</link>
<description><![CDATA[ (Jun 15, 2010) The summer solstice isn&apos;t until next Monday, but the earliest sunrise of the year was this morning, and the latest sunset isn&apos;t until later this month. St. Lawrence University astronomer Aileen O&apos;Donoghue shared these fun facts, and talked about how the crescent moon will be a good guide to Venus, Mars, Saturn and the star, Spica, over the next few days when she visited our studios this morning.(Ooops! Aileen says it&apos;s a waning crescent Moon near Jupiter on July 3 and 4...not a gibbous Moon.)

<description><![CDATA[ (Feb 2, 2010) If you can brave cold, crisp weather, there are plenty of treasures for stargazers in the February night sky — Mars, Jupiter and the constellation Orion.
