Then there's James Weiss our Master of Microscopes, providing all of the beautiful footage you see on your screen. Matthew Gaydos is our producer and editor, taking my narration and Jame's footage and turning them into actual videos that you can watch. Last, but certainly not least is Deboki Chakravarti, our writer on Journey to the Microcosmos, the person who brings the Microcosmos to life with her storytelling and her exhaustive research."

Journey to the Microcosmos- How Diatoms Build Their Beautiful Shells

"Well, for one, [diatoms use silica because] it's cheaper than both making and assembling your own materials. The silica is already out there, so why not take advantage of it? One study found that the materials in the diatom's frustules might help the organism take in carbon dioxide, improving their photosynthetic capabilities. These advantages seem to translate over into the immense capacity of diatoms to grow and dominate over other algae that share their waters. Taking over a body of water is all fun and games until the silica runs out."

CC: "Deboki has been with the channel since almost the very beginning. In fact, the first script she ever wrote for Journey to the Microcosmos, was our episode about diatoms back in 2019. Since we're here today to discuss diatoms once again, we thought it would be fitting to use this opportunity to introduce Deboki's new role, as another host of Journey to the Microcosmos. I'll still be here, narrating most of the episodes, but from time to time, you'll hear Deboki hosting a video instead of me. With her experience, not only in writing over 70 episodes of Journey to the Microcosmos, but also with her PhD in Biomedical Engineering and as a host on Crash Course: Organic Chemistry, I could not be more excited to have her join me on this journey. So, now I am going to hand the microphone over to Deboki so she can teach you more about diatoms!"
