Air Apparent
An atmospheric episode.

(Repeat) Whether you yawn, gasp, sniff, snore, or sigh, you’re availing yourself of our very special atmosphere.   It’s easy to take this invisible chemical cocktail for granted, but it’s not only essential to your existence: it unites you and every other lifeform on the planet, dead or alive.  The next breath you take likely includes molecules exhaled by Julius Caesar or Eleanor Roosevelt.

And for some animals, air is an information superhighway.  Dogs navigate with their noses.  Their sniffing snouts help them to identify their owners, detect trace amounts of drugs, and even sense some diseases.  Find out what a dog’s nose knows, and why no amount of bathing and dousing in perfume can mask your personal smelliness.

Plus, why your own schnoz is key to not only enjoying a fine Bordeaux, but to survival of our species.

(Repeat) We’re hearing about harassment of, and barriers to, women seeking careers in politics and entertainment. But what about science? Science is supposed to be uniquely merit-based and objective. And yet the data say otherwise. A new study reveals widespread harassment of women of color in space science.
