Hey everyone! Today, we’re diving into some fascinating topics and answering questions about my favorite things. Let’s explore some cool science and history together!
Did you know that the first evidence of fire on Earth dates back about 419 million years? When I visited the paleobotanical collection, I learned from Ian Glasspool, the collection’s manager, about a vial of ash that shows this incredible event. Back then, photosynthetic bacteria were evolving into fungi, and somehow, they caught fire. This discovery shows us that we can trace significant events in Earth’s history through physical evidence, opening up endless possibilities for understanding our world.
Let’s talk about sauropods, particularly Amphicoelias. This gigantic dinosaur, known from just a few fossils found in the 1870s, might have been up to 60 meters (or 200 feet) long! That’s like five and a half school buses lined up. It’s surprising that we haven’t found more evidence of such a massive creature.
Insects have some incredible adaptations. Take the bombardier beetle, for example. It can shoot out a hot, chemical spray at 100°C (212°F) to defend itself from predators. Nature is full of amazing survival strategies!
One of my favorite classes was painting with Mr. Gulbransen. He let me set up an easel in the back of the classroom and shared stories about living in a tipi in Wyoming. He also helped me get scholarships for school, making a huge positive impact on my life. Thanks, Mr. G!
I loved visiting the International Museum of Surgical Science in Chicago. They have a rare working iron lung, a 20th-century apothecary shop recreation, and even surgically removed kidney stones the size of your fist. It’s a fascinating place to learn about medical history.
While cultural and scientific institutions are amazing, I also appreciate the variety in grocery stores and the fun of arcade bars, where I can indulge my love for pinball.
About 4.4 million years ago, early humans began walking on two legs. This change might have been for carrying food and babies, moving through marshes, or traveling long distances. Whatever the reason, it allowed us to do so much more, including dancing and holding hands with others.
The human uterus is an incredible “in-house” baby-making factory. On a personal note, starting a Tumblr as a volunteer led to a full-time job at a major institution, which was a fantastic journey.
Sloths have a special relationship with certain algae species that only grow in their fur. This symbiotic relationship is a unique aspect of their biology.
At The Field Museum, we have an enormous collection of specimens. There are 3 million pinned beetles alone, not to mention the other 9 million insect specimens. We also have fascinating research on deep-sea octopuses and other invertebrates. Let’s not forget about mollusks, which deserve more attention!
Diaphonization, or clearing and staining, is a process where a specimen is treated to make its organs transparent. Then, dyes highlight the skeleton or muscles, creating a “see-through” effect. It’s a cool way to study animal anatomy!
That’s all for today! I hope you enjoyed learning about these amazing topics. Stay curious and keep exploring!
Using the information about the first fire on Earth, create a timeline that includes major events in Earth’s history. Include the evolution of photosynthetic bacteria, the development of fungi, and other significant milestones. Use online resources to add more details and present your timeline to the class.
Imagine you are curating a museum exhibit about sauropods like Amphicoelias. Design a poster or digital presentation that showcases what you have learned about these enormous dinosaurs. Include facts about their size, habitat, and the fossils discovered in the 1870s. Be creative and think about how you can make your exhibit engaging for visitors.
Research different insect adaptations, focusing on the bombardier beetle. Create a short video or presentation explaining how these adaptations help insects survive in their environments. Share your findings with the class and discuss how these adaptations might inspire new technologies.
Take a virtual tour of a museum, such as The Field Museum or the International Museum of Surgical Science. Choose one exhibit or collection that interests you and write a short report on what you learned. Include interesting facts and your personal reflections on the experience.
Learn about the process of diaphonization and its applications in studying animal anatomy. Create a simple model or drawing to demonstrate how this technique works. Discuss with your classmates how this method can help scientists understand more about animal structures.

Hey everybody! Welcome to The Brain Scoop. Today I’m going to answer some questions about my favorite things, because in Ask Emily episodes, you ask me a lot about my favorites, and I didn’t know. But now I do.
When I visited the paleobotanical collection, the collection’s manager, Ian Glasspool, showed me a vial of ash, which is the first known evidence of a fire ever burning on the planet—meaning that around 419 million years ago, when photosynthetic bacteria was forming into a kind of fungus, it caught on fire, and we have the physical evidence of that event. The idea that we can trace such a significant event back to physical evidence opened my mind to the possibility that we can potentially answer any question conceivable about mankind.
Sauropods! Especially Amphicoelias, which was an enormous dinosaur only known from a handful of fossils found and described in the 1870s before being accidentally misplaced. If this animal existed, it could have been up to 60 meters, or 200 feet long, which seems a little surprising that we wouldn’t be able to find more evidence of it considering it was about the length of five and a half school buses put together end-to-end.
Somebody just turned the lights off. It’s hard to beat insect adaptations—like how the bombardier beetle can fire out a cocktail of catalytic compounds in defense against predators. This vaporic acid comes out at about 100°C, or 212°F.
I really enjoyed painting class with Mr. Gulbransen because he let me set up an easel in the back of the classroom and would tell me stories about how after college he lived in a tipi in Wyoming with his girlfriend. He also helped me get a bunch of scholarships to go to school and had a huge positive impact on my life. So thanks, Mr. G.
I really enjoyed visiting the International Museum of Surgical Science here in Chicago. In addition to having a rare working iron lung on display, they also have a 20th-century recreation of an apothecary shop and surgically removed kidney stones the size of your fist.
I could say it’s access to amazing cultural and scientific institutions, but really it’s grocery stores and their diverse selection and arcade bars where I can attempt to overcome my insatiable desire for pinball.
That would have to be around 4.4 million years ago when early hominids stood upright and became bipedal. Whether that was for freeing our arms for food- and baby-carrying purposes, wading through marshy bogs, or crossing large distances more efficiently, perhaps it was for dancing, or the romantic notion that we wanted to walk hand-in-hand with our brethren. For whatever reason, it was a good thing we did, because now we can do so much more.
Bacon. I mean, the uterus as an in-house developmental baby-making factory is pretty remarkable. Probably the one where I started a Tumblr as a volunteer in a small university zoological collection, and it ended up resulting in a full-time job at a major institution. That was a good one.
Is that it exists at all. Probably that sloths have unique symbiotic relationships with certain species of algae that are only found growing in the microcosmic environments of their hosts’ fur.
I mean, you guys are asking me to pick between some pretty major collections here at The Field Museum. We’ve got 3 million pinned beetles, and that doesn’t include the other 9 million specimens in the insect division. We’ve hardly talked with Janet Voight about her work with deep-sea octopuses and other invertebrates, and let’s not forget the major neglect to discuss mollusks on this show. Seriously, we need more mollusk love on The Brain Scoop.
Diaphonization! Also known as clearing and staining, is a process in which a specimen is injected with enzymes that render the organs transparent. Then, it’s submerged in a solution of dyes that either adhere to the skeleton or the muscular system, resulting in a “see-through” animal with a highlighted mobility system. It is so cool.
We got it?
[Tom] We got it! Bam!
[Tom] Great.

Fire – A rapid chemical reaction that releases heat and light, often used in scientific experiments to study combustion and energy transfer. – In biology class, we learned how fire can affect ecosystems by clearing old vegetation and allowing new plants to grow.
Bacteria – Microscopic single-celled organisms that can be found in various environments, some of which are beneficial while others can cause diseases. – Scientists study bacteria to understand how they help in digestion and contribute to the nitrogen cycle in ecosystems.
Sauropods – A group of large, long-necked dinosaurs known for their massive size and herbivorous diet. – The sauropods roamed the Earth millions of years ago, and their fossils help scientists learn about prehistoric life.
Adaptations – Changes in an organism’s structure or behavior that improve its chances of survival in its environment. – The thick fur of polar bears is an adaptation that helps them survive in cold Arctic climates.
Insects – A class of small arthropods with a three-part body, six legs, and usually one or two pairs of wings. – Insects play a crucial role in pollination, which is essential for the reproduction of many plants.
Evolution – The process by which different kinds of living organisms develop and diversify from earlier forms over generations. – Charles Darwin’s theory of evolution explains how species adapt to their environments through natural selection.
Biology – The scientific study of life and living organisms, including their structure, function, growth, and evolution. – In biology class, we dissected a frog to learn about its internal anatomy and organ systems.
Relationships – The interactions between different organisms and their environments, which can include symbiotic, competitive, and predatory relationships. – The relationship between bees and flowers is mutualistic, as both species benefit from the interaction.
Specimens – Samples of organisms or parts of organisms used for scientific study and analysis. – The biologist collected specimens of various plants to study their cellular structures under a microscope.
Anatomy – The branch of science concerned with the bodily structure of humans, animals, and other living organisms. – Understanding the anatomy of the human heart helps doctors diagnose and treat cardiovascular diseases.
