Fighting Banana Blight | Do Birds Sing In Their Dreams?

America’s most-consumed fruit is at risk from a fungal disease. Researchers in North Carolina are on a mission to save Cavendish bananas. Also, birds move their vocal organs while they sleep, mimicking how they sing. Scientists have translated those movements into synthetic birdsong.

Fighting Banana Blight In A North Carolina Greenhouse

Bananas are the world’s most popular fruit. Americans eat nearly 27 pounds per person every year, according to the U.S. Department of Agriculture. A deadly fungus could destroy most of the world’s crops, but a company in Research Triangle Park is trying to save the banana through gene editing.

When it comes to growing bananas, RTP may not be the first place that pops in your head. But Matt DiLeo has a greenhouse full of them.

DiLeo is Vice President of Research and Development at Elo Life Systems, a biotechnology firm that’s exploring how gene editing can improve fruits and vegetables.

On a cloudy afternoon in early April, DiLeo opened the greenhouse door and stepped into a steamy atmosphere with a slightly floral odor. This greenhouse is packed floor to ceiling with banana trees. You’ve got to duck to keep the giant leaves from hitting your face. Some of the bananas are yellow, some are green, some are tiny and pink. DiLeo says they all share an important trait.

“Many of these are naturally resistant to the TR-4 fungus,” DiLeo said.

Do Birds Sing In Their Dreams?

When birds sleep, what are they dreaming about? Researchers from the University of Buenos Aires have figured out a way to tap into bird dreams. When a bird slumbers, its voice box, called the syrinx, can move in ways that are similar to when they sing while they’re awake. Essentially, birds are silently singing in their dreams.

Now, researchers have figured out how to translate that vocal muscle movement into a synthetic bird song, meaning you can listen to how birds sing in their dreams.

Guest host Maggie Koerth talks with Dr. Gabriel Mindlin, professor of physics at the University of Buenos Aires about his latest bird dream research, published in the journal Chaos.
