Nearly 10 years ago, in February 2015, we welcomed readers to the I Spy Physiology blog. The aim of this new content was to answer the question “What is physiology?” in a way that nonscientists could easily understand.

Armed with a small group of American Physiological Society (APS) members and staff, weekly posts highlighted the physiology that surrounds us in our everyday lives. Throughout the years, we’ve welcomed new contributors and amplified research in our journals. We’ve reported on APS meetings, including our specialty conferences, Experimental Biology and the American Physiology Summit.

We’ve tweaked the format of the blog and won awards for our content as we’ve continued to explore physiology in 400 words or less—most of the time.

This post is our 500th. We’d like to thank our blog contributors for lending us their expertise and science communication talent as they’ve shared their work with us, taught us about the fundamentals of physiology and had some fun with seasonal topics.

A big thank you also goes out to our readers. Without you, there would be no audience to read about the superhero qualities of a breakfast cereal and what happens to astronauts’ bodies in space. In the blog’s first year, 5,700 visitors clicked on our page to look around. So far in 2024, more than four times that number have come to see what’s new in the field of physiology.

Cheers to 500 🥂 and here’s to another 500 more informative, intriguing and intellectually stimulating posts.
