TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for Halloween 2021.  Besides focusing on autumn’s festival of fun and fright, this episode is part of a series this fall about water connections to the human body and human biology.

SOUND – ~9 sec

That eerie sound of a tree creaking in October wind sets a seasonal stage for a Halloween challenge: exploring how Halloween, water, and human biology all connect.  Sound like quite a trick?  Well, have a listen to some Halloween music for about 50 seconds, and then we’ll treat you to some examples.

MUSIC - ~50 sec – instrumental

You’ve been listening to “A Little Fright Music,” by Torrin Hallett, a graduate student at the Yale School of Music.  And here are six matches of Halloween creatures or images with water in the human body.

1.  Skeleton images rattle around everywhere for Halloween, and in living skeletons water is a significant component of bones and cartilage. 

2.  Pretend blood covers many-a Halloween costume, and over half of the volume of blood is plasma, which in turn is over 90 percent water, and water is also a major component of blood cells.

3.  A muscular costume is part of pretending to be a super-strong character like Wonder Woman or Superman; and water plays a significant role in muscle structure and function; in turn, muscle is an important water-storage area for the body.

4.  The monster in movie versions of “Frankenstein” was brought to life by electricity, and the cells of our nervous system transmit messages though electrochemical impulses, using sodium and potassium ions in a water-based solution.

5.  If fiery or icy creatures need some temperature regulation, water’s the body fluid that does it.

And 6.  Flashing and watching from many creatures on Halloween night are eyes, either scary, suspenseful, or super-powered; and eyes have chambers containing aqueous humor and vitreous humour, two fluids that consist mostly of water and that maintain the shape of the eyes.

This Halloween, imagine being a creature that’s about 60 percent composed of an amazing substance with unique powers to dissolve other substances, absorb and release heat, and withstand being compressed.  What would you be?  Why, the water-based human being that you are!

Thanks to Torrin Hallett for composing this week’s music for Virginia Water Radio, and we close with another listen to the last few seconds of “A Little Fright Music.”

MUSIC - ~13 sec – instrumental

TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of October 25, 2021.  This episode is part of a series this fall about water connections to the human body and human biology.  We start this week with three mystery sounds, all related to a very numerous group of disease-causing, or pathogenic, microbes that have enormous impacts on human health.  Have a listen for about 20 seconds, and see if know this microbial group.  And here’s a hint: big hits on social media are said to spread like this group.

SOUNDS – ~19 sec

If you guessed viruses, you’re right!  You heard a person coughing due to a viral disease; handwashing, an important method of reducing viral transmission; and a spray bottle of isopropyl alcohol, an effective disinfectant against many kinds of viruses.  With attention focused this fall both on the COVID-19 coronavirus and the annual influenza virus season, we explore in this episode some basic information about viruses and some viral connections to water.  Here are 10 key points about viruses.

1.  Viruses are one of four groups of microbes responsible for human disease, along with bacteria, fungi, and protozoa, which are single-celled animals.  As a group, viruses are the smallest of these microbes, although some are larger than some bacteria.

2.  Viruses aren’t made up of cells, but instead exist as particles composed primarily of molecules of protein and nucleic acids, that is, DNA or RNA.  They require a cellular host for reproduction, called replication. 

3.  Viruses are more abundant than all of the cellular-based living things on earth.

4.  All living things are infected by viruses. 

5.  Viruses don’t always cause disease in infected hosts, but many kinds do cause significant diseases in humans, other animals, and plants.

6.  Viral disease can result from viruses taking over or inhibiting their host’s cellular biochemical processes, or by cell destruction as new virus particles exit cells after replication. 

7.  Depending on their type, viruses can be spread through air, in water, from surfaces, by animal vectors, or through exchange of blood or other body substances.

8.  Water-related spread of viruses can occur through water contaminated with human waste, and through animal vectors connected to water, particularly mosquitoes. 

9.  Significant human diseases from water-borne viruses include intestinal disease, particularly diarrhea; hepatitis, or liver inflammation; inflammations of the brain, spinal cord, or heart; and possibly cancer.  Viral diseases spread by mosquitoes include Yellow Fever, Dengue, West Nile, and others.

And last, but not least, handwashing with clean water and soap is important for reducing the spread of viruses through objects and surfaces—collectively called fomites—with which humans come into contact.

Thanks to Freesound.org user n__audioman for making the coughing sound available for public use.  Here’s hoping we all hear less of that sound and more of the handwashing and other preventative measures that keep viruses—water-borne and otherwise—somewhat at bay.
