Science Vs: Episode Summary – "Video: How Bats Get High"

Release Date: July 20, 2023 | Host: Spotify Studios

Introduction to Bat Fascination

The episode opens with an enthusiastic listener expressing their admiration for bats, noting their unique appearance:

Enthusiastic Listener [00:38]: "I love bats. I love bats. Yeah. Oh, wow. It really just looks like a possum flying. Doesn't does."

The host acknowledges this fascination and segues into exploring the enigmatic nature of bats:

Host [01:00]: "I had that same feeling. I guess the question it made me think is like, do I know bats at all? [...] bats are so weird in so many ways, including how they get high."

Introducing the Expert: Sharon Swartz

To delve deeper into the world of bats, the host introduces Sharon Swartz, a renowned bat researcher:

Host [01:22]: "Our guide today is top flight bat researcher Sharon Swartz."

Sharon shares her passion for animal movement:

Sharon Swartz [01:25]: "I'm interested in how animals move. There's nothing as compelling to me in the biological world as animal movement. Movement."

The Marvels of Bat Flight

Sharon and the host explore the extraordinary flight capabilities of bats. They highlight the diverse flying speeds and maneuvers bats can perform:

Host [01:33]: "And bats can do astounding things in the air. Some bats fly almost 100 miles per hour. Others migrate long distances. Some hover. Some hunt. And then there's acrobatics that only bats can pull off."

Sharon emphasizes bats' proficiency at low-speed flight:

Sharon Swartz [01:50]: "Really, the superpower of bats is that most bats are really good at flying extremely well at low speeds."

The host connects this to their ability to execute precise landings:

Host [01:56]: "And for bats, this means they can achieve difficult landings."

The Physics of Bat Landings

Discussion turns to the unique landing techniques of bats, particularly their ability to land upside down:

Sharon Swartz [02:08]: "They can land upside down, going upward as they slow down."

The host reflects on the complexity of this maneuver:

Host [02:17]: "Exactly. I never thought about how hard it might be to land upside down on the top of a cave. Like, as you slow down, gravity wants to pull you down, but you need to go up."

Sharon elaborates on the physical challenges involved:

Sharon Swartz [02:30]: "So this is really a challenging physical problem."

The enthusiastic listener draws an analogy to landing pads:

Enthusiastic Listener [02:15]: "That's their landing pad. It's up."

Bat Wing Anatomy and Control

The conversation shifts to the anatomical marvels that enable such flight precision:

Host [02:35]: "Partly it's their special wings."

Visual description of bat wings is provided:

Enthusiastic Listener [02:43]: "Wow. It looks like a spider web."

The host explains the structure:

Host [02:45]: "Yeah. So that web is made up of ultra light connective tissue and muscles."

Sharon discusses the intricate muscle control and joint flexibility:

Sharon Swartz [02:50]: "So bats are able to use these muscles to change the state, stiffness of... the skin that gives them control. Along with their many wing joints, a bat wing has almost as many joints as a human hand. A wrist and an elbow and a shoulder and then many finger joints. And so that lets a bat control the wing in a way that is not feasible for any other flying animal."

Comparative Acrobatics

The host draws a parallel between bat wing movement and human athleticism:

Host [03:19]: "And certain bats can use their highly maneuverable wings to stick the upside down landing. So you know how a gymnast or a figure skater changes their speed by moving their limbs in relation to their body?"

Enthusiastic Listener [03:31]: "Yes."

Host [03:31]: "Sharon showed that bats do the same thing with their wings."

The listener likens bats to aerial acrobats:

Enthusiastic Listener [03:39]: "Ooh, there's the flip. Flip and grab. They're like little Simone Biles of the sky."

Host [03:46]: "Yeah. They are putting the bat in acrobatics."

Enthusiastic Listener [03:49]: "It's very cool."

Conclusion and Teaser

The host hints at even more remarkable aspects of bats beyond flight:

Host [03:52]: "But flight is not even their most amazing bat tribute. So that is why you gotta hear the whole episode."

Listeners are encouraged to explore the full episode to uncover additional fascinating details about bats.

Key Takeaways

• Exceptional Flight Control: Bats possess highly maneuverable wings with numerous joints, allowing them to perform complex aerial maneuvers and precise landings, including upside-down landings.

• Anatomical Adaptations: The structure of bat wings, composed of ultra-light connective tissue and muscle, provides bats with unparalleled control and flexibility in flight, comparable to the dexterity of a human hand.

• Behavioral Acrobatics: Bats exhibit gymnastic-like movements in the air, adjusting wing positions to control speed and direction, making them the "Simone Biles of the sky."

• Expert Insights: Sharon Swartz highlights the significance of studying animal movement to understand the biological marvels of creatures like bats.
