Introducing Joyful Microbiology Activities

Thu, 27 Apr 2023 14:34:42 +0000

I'm thrilled to announce that in this podcast episode, I read the introduction chapter of my brand new ebook, Joyful Microbiology Activities. This book has been a labor of love, and I'm so excited to share it with you.

Microbiology is a fascinating subject studying organisms that are often viewed negatively as “those gross and scary germs.” However, my goal with this ebook is to shift that perception and show you that microbes are incredibly important in our lives and can even bring joy! Through a collection of hands-on activities, I hope to inspire your curiosity, help you gain a deeper understanding of the microbial world around us, and allow you to have some fun with these tiny but mighty creatures.

Whether you're a science teacher, a parent with curious kids, or simply someone who loves learning new things, there is something for everyone in this ebook. From exploring the microbes in our homes and living in our yards to investigating the microbial communities in soil, this book covers a wide range of topics that will spark your interest and expand your knowledge. These activities work for multiple ages and grade levels, with some very simple activities that are suitable for elementary students and others for middle and high school students.

I’ve had people ask me if I’ll release a print version of it eventually, and my answer is maybe. For now, it makes the most sense to me to provide it as an ebook so that you can print out the pages for the single activity you plan to do. That way, you can also write your notes on the printed pages because I encourage documentation of your results in each activity.

I'm truly passionate about sharing the joy of microbiology with others, and I hope that this book will inspire you to see the world of microbes in a new light. So sit back, relax, and join me as I read the introduction chapter of Joyful Microbiology Activities.

How To Nurture Your Skin Microbiome: Dr. Julie O’Sullivan

Fri, 30 Sep 2022 22:00:00 +0000

A vast number of microbes live on our skin, in our gut, and almost everywhere else you can imagine on and in our bodies. Collectively, these microbes are called the human microbiome and play a crucial role in our health and well-being. Different locations on our bodies contain a specific set of microbes, which are individual microbiomes, i.e., the gut microbiome, skin microbiome, and oral microbiome. The skin microbiome is a relatively less researched microbiome on our bodies but is incredibly important for the health of this protective outer barrier.

On the podcast, I talked to Dr. Julie O’Sullivan, a skin microbiome researcher at APC microbiome at the University of College Cork in Ireland, about how these microbes keep us healthy and how when they get out of balance can cause issues like eczema and acne. She also gives us some practical tips for maintaining a healthy skin microbiome and shares her thoughts on skin microbiome tests.

Topics covered in this episode:

What is the skin microbiome?
How does the skin microbiome keep us healthy?
How are microbes involved in eczema and acne?

Microbiology Activities for High School Students: Jessica Popescu

Thu, 28 Apr 2022 15:40:00 +0000

The K-12 curriculum does not cover microbiology much at all. But this area of science matters. Children need a complete understanding of the microorganisms that play roles in our health, like the microbiome, and diseases, like germs. That way, they’ll carry these concepts into adulthood, ultimately helping keep them healthier.

Despite the lack of microbiology education in K-12, some high schools offer full microbiology courses. So, to learn more about what it’s like teaching microbiology at the K-12 level, I talked to high school microbiology teacher Jessica Popescu.

Whether you’re an educator, microbiologist, or science enthusiast, you’ll find something interesting in this episode of the Joyful Microbe podcast.

Micronovo’s Microbiology Books for Kids: Dr. Mike Manefield

Fri, 25 Mar 2022 16:00:00 +0000

How do you explain microbiology to a child?

It’s an abstract topic since you can’t readily see microbes due to their size. So, to help your kids visualize microbes, you can read them a children’s book specifically about microbiology.

I’ve featured a few excellent microbiology books for kids before on Joyful Microbe. But after I found out about Dr. Mike Manefield, a microbiologist who writes children’s microbiology books, I knew I needed to chat with him. He’s a full-time professor at the University of New South Wales in Sydney, Australia, and writes these incredible books as a hobby. His publishing company is called Micronovo.

His desire with these books is to communicate the complex stuff of microbiology and share it with his friends, family, especially his children, and the world so they can understand why the microbes are so cool.

Grab one of these microbiology books written by a microbiologist to help your kids understand the importance of microbes in our world. Learning the concepts from these books will equip them early in life with a well-rounded view of the microbial world, seeing both the good and the bad, so they can make educated, science-based decisions as they grow.

Topics covered In this episode:

Micronovo: books about microbiology for children

Painting with colorful antibiotics from bacteria: Dr. Vineetha Zacharia

Mon, 28 Feb 2022 18:45:00 +0000

The words bacteria and beauty are not usually associated. But some bacteria make beautiful colors that span the entire rainbow. And one type of bacteria called Streptomyces coelicolor makes an antibiotic with a lovely blue pigment. This blue-colored antibiotic, called actinorhodin, inspired microbiologist Dr. Vineetha Zacharia, a postdoctoral researcher at the University of California, Berkeley studying this soil bacterium, to use it like watercolor paint to create art.

So, read on or listen to the podcast episode to learn about her work with Streptomyces coelicolor and how she got into what she calls “Actino Art.”

Introduction to Lichens: Dr. Klara Scharnagl

Mon, 16 Aug 2021 05:00:00 +0000

What’s something from the microbial world you can go outside and almost be guaranteed to see? I’ll give you a hint. They are those gray, green, yellow, orange, red, and other colorful splotches on trees and rocks. I once even saw one while I was mountain biking. It was growing on an old boot! Those are lichens.

But what are these things we call lichens? And what are they doing hanging out on rocks and other substrates that don’t move? That’s what we’ll talk about in this episode of the podcast. Lichens fall within the microbial world because they are composed of microbes. You’ll learn from lichenologist Dr. Klara Scharnagl why these organisms are so cool and how to enjoy them for yourself in your daily life. You can think of this as your introduction to lichens, learning from an expert in lichens.

How science art helps us understand microbiology: Dr. Lizah van der Aart

Mon, 19 Jul 2021 22:04:45 +0000

We talk about microbes on this podcast. But let’s face it. If you don’t see a picture of them, it’s difficult to imagine what’s going on in the microbial world. That’s why microscopy is so helpful. It allows us to actually see the invisible communities of bacteria, fungi, algae, viruses, archaea, and protozoa.

But sometimes, art does a better job of representing the microbial world and all of its intricacies and nuances. So that’s what my guest on the podcast, Dr. Lizah van der Aart, does. They create microbiology art as a professional science artist and illustrator, helping others express difficult concepts that need descriptive visuals.

Another thing I love that Lizah does is create microbiology art that anyone can purchase from their online shops, things like enamel pins of bacteria that we talk about in the episode, tote bags, stickers, and coffee mugs. These different products they sell allow us to outwardly express our love, passion, and enthusiasm for microbes.

If you’ve ever wanted to meet a science artist, here’s your chance. We discuss Lizah’s background as a PhD microbiologist and how they decided to combine their passion for microbiology with art to create a career. Lizah works with different clients on science illustration projects, and I’ve actually had the pleasure of working with them on a project of my own. So, we discuss the process of working together to turn my idea of what I thought would be the best Winogradsky column color guide into a real thing. It ended up looking amazing and is a truly beautiful representation of the colorful patterns you might see in your column. Ya gotta see it.

In this episode, you will learn about…

How bioluminescent bacteria drew Lizah to microbiology
What makes the soil bacteria Streptomyces so delightful?
An example of the difficulties in categorizing bacteria: Thermoactinomycetes

Using viruses to battle superbugs (phage therapy): Dr. Jessica Sacher

Thu, 01 Jul 2021 14:30:00 +0000

Imagine the last time you were sick and needed antibiotics...now imagine that you took the antibiotic, but the infection didn’t go away. The antibiotic didn’t work. And then the next one didn’t. And then the next one, all the way until none of them worked.

It happens. And although I’ve never personally experienced this, I’d think it would be terrifying.

What would you do? Recently, some doctors have started using viruses called bacteriophages (or phages for short) that can kill bacteria. It’s called phage therapy, and it’s saving people’s lives.

In the US, phage therapy is something doctors can access only through special authorization by the FDA. But it’s gaining popularity. And in some countries, phage therapy is actually the preferred treatment of choice, but we’ll get to that later.

So, on this podcast episode, I talk to Dr. Jessica Sacher, who is the co-founder of Phage Directory, an organization that connects doctors and patients to scientists that work with phages. Phage Directory simplifies the process of finding the treatment patients desperately need for bacterial infections that have stopped responding to antibiotics.

When the antibiotics stop working, phages can cure superbug infections.

In this episode, you will learn about…

An introduction to viruses
Phages: viruses that infect bacteria
How to see viruses
Most viruses do not make us sick
Could phages ever make us sick?
What makes phages so specific to the bacteria they infect?

Using microbes to treat infections: Dr. Brian Klein

Wed, 16 Jun 2021 14:56:12 +0000

What if doctors could use microbes to treat infections? It might seem counterintuitive at first because, well, aren’t the microbes the problem?

Not really. Our bodies have microbes living in and on them, which is a good thing. These organisms, called the human microbiome, help keep us healthy. Because of the amazing benefits of having these microorganisms as a part of us, why couldn’t we try and take bacteria or other microbes that are considered “healthy” and use them to fix some of the problems we experience due to “bad” microbes?

There are numerous companies developing ways to use microbes to fix microbial problems. So, in this podcast episode, I chat with Dr. Brian Klein. He is the co-founder and CEO of BrickBuilt Therapeutics, a company that is developing microbiome-based therapeutics to treat infections of the mouth.

We discuss the oral, skin, and gut microbiomes of humans and the potential to treat diseases or disorders affecting those sites of the body using microbes.
