AND NOW FOR SOMETHING COMPLETELY DIFFERENT.

Yes, Kristen has had a busy couple of weeks and couldn't find time to record an episode of Early Bird Science for this morning.

However, her Headshake co-host Nathan A. Libby has offered to take over the program (with Kristen's blessing, of course) and change the content over from real science to proven NON-science.

Kristen will be back in two weeks with another regular episode of Early Bird Science, but for now, please enjoy some nonsense.

Kristen addresses the argument over whether human blood is blue. She talks about common misconceptions and what gives blood its color. As a bonus, she also talks about the variations in colors of blood in other animals.

CORRECTION: In this episode, Kristen says “octopi” to indicate the plural of “octopus.” Because “octopus” originated from Greek and not Latin (which does use “i” to pluralize words) and because “octopus” has been a word in English for a long time, Kristen would have preferred to pluralize the word using English rules: “octopuses.”

Self-driving, or autonomous, cars are an appealing technology with tons of transportation potential, but one major barrier that may afflict many future drivers-turned-passengers is motion sickness.

Kristen discusses a new superglue from researchers at the University of Pennsylvania that imitates the way snail slime works. The adhesive is not only super strong - It stuck a human to the ceiling! - but is also reversible, a combination of properties that is currently rare and in-demand in areas like auto manufacturing, household use, robotics, research, and medicine. Kristen also gives an overview of how this new invention could make it to you as a consumer in the future through a process called “technology transfer.”

To the moon! ...Almost!

Kristen discusses what happened during the Chandrayaan 2 mission on September 7, 2019 when the Indian Space Research Organization (ISRO) lost contact with their spacecraft as they were trying to land it on the moon. She talks about why the setback is a bummer but also gives her opinion on why this mission and others like it bring hope for space exploration and even human purpose.

Have you ever wondered what those squiggly lines mean on heart monitors in the hospital or on TV? More importantly, has a friend of yours ever gotten a heart beat tattoo, and you really wanted to critique it? This episode is part 2 of 2 on EKGs, so if you haven’t yet listened to Part 1, we encourage you to go back one episode to get caught up.

In Part 2 Kristen discusses:

  • Parts of an EKG signal
  • Heart electrophysiology
  • What doctors can tell from EKG signals, and
  • Examples of unhealthy signals

Have you ever wondered what those squiggly lines mean on heart monitors in the hospital or on TV? More importantly, has a friend of yours ever gotten a heart beat tattoo, and you really wanted to critique it? In this episode, Kristen talks about what you’re seeing when you look at an EKG. As AV explains, Kristen got a bit carried away recording this topic, so it is split into two parts.

Part 1 discusses:

  • What an EKG looks like
  • A brief review of anatomy of the heart
  • What an EKG is and is not recording
  • The definition of “EKG,” and
  • How EKG recordings are made

Listen for Part 2 in the next episode for more.
