Oh hey, it's your shoe repair guy who just is curious when you're going to have children, and you're like, can I just have my shoes? Ali Ward back with just a teeny tiny tanny Ology with a very big guest. It is molecular and it's galactic all at once. Let's get right into it. But first, thank you to everyone supporting the show on Patreon. At patreon dot com slash Ologies, it costs about twenty five cents an episode to join and submit questions to Theologist, so you can meet me
over there if you want to do that. Thank you for hitting subscribe and rating the show, which takes literally two seconds and costs you no dollars. And also for leaving reviews, which maybe takes sixty seconds if you don't proofread, which I don't even mind, and I read and appreciate everyone, such as this one left this week by Philo Sophia, who says I'm writing this review well, curled up with
my dog under my Ologies blanket. Waiting for my virtual physics class to start online school for my senior year of high school has been tough, but Ology, says continually reminded me of the world's many wonders and curiosities. Thank you, Philo Sophia. Thank you also in exchange, please teach me how to use TikTok okay. Molecular biology So molecule comes from the Latin for mass or moles or extremely minute particle,
and biology, of course, is the study of life. So molecular biology is the study of the little, itty, bitty, squiggly intricate structures that keep us alive and breathing and finding off illnesses and falling in love and digesting a pisa. So molecular biology is how molecules interact with each other to form life processes, and how proteins do a lot
of our dirty work. But this episode is really exciting because we're also learning quite a bit about how to communicate science from someone who has done a TEDx talk and been recognized by Fortunes forty under forty and also MEGANI Stallion. More on that in a moment. This ologist, though, got her bachelor's and master's degrees in biology from Buffalo State University in New York it is very cold there, and has been an assistant professor of biology and a
STEM college coordinator for high school students. Has worked in a private lab researching cancer cures and is just a few tidy months away from getting her PhD in Communicating science, so she is busy now. I have been a fan of hers for quite a while since seeing her early pandemic video Wipe it down, and we have gotten a chance to zoom a few times and hang out talking about TV projects she's working to launch. And I have retweeted her so many times that people assumed she had
already been a guest on Ologies, but she hadn't. So we hopped on a call to make it official and talk about what a molecular biologist does, the grossest parts of her lab, work space, camp, how different brains absorb information, her PhD plans, protein folding, DNA strands, and more with science communicator and molecular biologist almost doctor Raven the science even Baxter.
My name is Raven Baxter and my pronouns are she her.
You're not the only Raven Baxter that people may have heard of. Should you get that a lot?
I get this a lot for the past. I think it's been not seventeen years, it's or maybe has been seventeen years.
Such a good name, you know, I.
Loved having it until the Disney Channel came in and just decided they were going to do do their own thing.
I think a lot of people think of you as Raven the Science Mayven. Like a lot of times, I don't even think about you having a last name. I just think of you as Raven the Science may Be.
That's good to know because I feel like I sometimes google myself as a metric, like I google Raven Baxter to see how many that's so Raven pages come up, and that's been my metric for how well I've been doing.
Yeah, that's got to really screw up here Google alerts probably.
A little bit, a little bit.
When did you come up with the Raven the Science Maben name?
So I remember this specifically happened in a car and it was there was just this day where I decided I was a YouTuber and I was documenting my hair journey. A lot of people don't realize that I didn't start growing my platform under Science. I was growing under like hair and Beauty, and I had a pretty large following and people really enjoyed me. But I personally felt like I had more to contribute to the space than just
talking about hair. So that like, well, if I'm not gonna you know, I was branded under really Raven at the time, and I said, well, I want to do something that science related. I just came up with Mayven. My aunt calls me Raven Maven, and then I'm like, well, what about Raven the science maven? Right, Like, Maven's an expert in something. And at that time, I had, you know, just gotten a master's in biology. So I'm like, oh,
I'm an actual Maven of science, you know. So that's that's how it happened.
Done and done. Do you feel like you kind of learned a lot of the ropes in terms of how you wanted to communicate doing your hair channel and your beauty channel.
Yeah. I think it was really good practice for me because I guess when I started YouTube, there was a really set way for doing a video and there were just a set of norms that you kind of had to abide by when you're making content. And then for the type of community I was making content for the hair community, it's it's called sister locks and Sista loss.
Community can be can be a little disapproving when you stray from traditional like hair care methods, etc. Like I was doing a lot of things that people didn't do that was kind of like forbidden. For example, when that hair paint wax. I don't know if you got into this trend, but those colored waxes that you could put in your hair instead of dyeing your hair, like it was a temporary way of adding color. I would put that in my locks and people would be like, no,
you're not supposed to do that. No, it's gonna get stuck in your hair, and this and that and which is true. But I wanted to try it right, Like I wanted to have fun experimenting with my hair, and that meant doing a lot of things that people were like,
oh my god, why is she doing that? Like that's not how you're supposed to do it, But I did it anyways, and I did it in a way where I was just unapologetically like, hey, I just want to try new things and learning how to how to create content without being afraid of what people think, or kind of just being true to yourself without worrying about who cares or who doesn't want to see you have fun with X, Y and Z has really been a good
lesson for me. As I've talked about science and it was a good primer for me to understand that understand how to come into this science communications space without worrying about how I'm presenting the material. You know, if everybody's gonna like it, or is everybody gonna approve of me doing X, Y and Z and just having fun with it. It was really good practice for that.
Okay for a quick discography of music videos that have gotten the world's attention, One of Raven's first was titled Big Old Geeks, featuring her dancing around a sports car in these tall, shimmery boots. Wearing a lab coat. She was joined by other female scientists.
Big Geek in his house and me running through the space. I know, regular degula, man, I'm really malecula. I gotta see the big picture. I'm a significant figure. Get more degrees, I get bigger. J'all ten percent but on.
And then of course there was the early pandemic disinfectant tutorial Wipe It Down, which was a homage to Fox's wipe me Down.
Let's all wipe it down, Blowox, wipe it down. Leicea wipe it down, Blowox, wipe it down. What's the body, what's the hand, and what's the hand too, the soaps from it down and show me how you do it.
YouTube comments seeing her praises saying this song is catchy as hell, no pun intended. And I'm a sixty five year old man and you have me bopping to this jam when I'm washing my hands at home now. Her most recent video offered up info on vaccine technology and antibodies the category of biology.
Listen on immunology, little microbiology. This is the terminology. I got the vaccine and now you got me on the right night? Be so noted, hay us want to see him?
So is night was? It retweeted by Megan thee Stallion. It was children dreams can come true. And you've been doing experiments since you were a kid, right, You've been mixing things around the house. And have you always been kind of science minded?
Absolutely? I definitely, I've always loved science. I was an only child and raised in a single parent household, and my mom worked really hard, and a lot of times it was kind of up to me to entertain myself, and quite often I would find that I'd just get drawn to the natural environment and looking at the clouds or digging in the dirt. Things that kids, do you know? But I was very I feel like I engaged in scientific inquiry from a very young age.
So meteorology and clouds to grass stains to a lab coat? How did this journey happen? So Raven dipped into Space Camp, which until adulthood, I thought Space Camp was a fictitious place. I thought it was like the Wonka Factory. I had no idea it really existed. But since nineteen eighty two, nine hundred thousand campers have gone through their program, and among them a bunch of real life astronauts and also Raven.
I didn't even realize Space Camp was real for a long time when I was a kid, Like what was that?
Like?
How did you pair down what direction and science you wanted to go toward?
That's funny because it largely happened at space Camp. I was pretty set on being an astronaut until I went to Space Camp and found out I was afraid of heights down because at Space Camp they really do give you junior astronaut training. So they put us in a high altitude flight simulator, and I immediately realized that I really don't like flying, and I really don't want to be in a spacecraft. So I really had no choice but to focus back down to Earth literally and pursue
like sciences that are earth based. When I went to college, I tried different majors out and I started an environmental law and policy and then later as our transition and in my academic journey, found genetics and was so thrilled to learn that our bodies are so cool that they speak their own language, which is the genetic code. And I'm sitting in this class like, oh my gosh, you know, none of my friends are in this class. They have
to learn about this. This is so cool. Our bodies are speaking a language, and like we're the only ones that are taking a class on it, right, So like, not only did I think it was super cool, but I wanted to share that with everyone that I knew. But I just went down that rabbit hole genetics and molecular biology, and I never came out. So the language is our DNA, the genetic code, and it is a
sequence of nucleotides that contain instructions for proteins. Yes, and those proteins are doing the work inside of ourselves to generate our life processes. So the way that I like to see It is just a scaled bound version of how cities work. Where you have the mayor, you know, and he's at city hall and that's that's often like the central point of a city. And the mayor has like his staff that he talks to, and you know, he tells so and so to do this, and then
they go do that. So it tells another person to do another thing, and they go do that job. And everything that happens out from city hall affects the entire city. And that's how I think about moleculary biology. It's a super simplified version of it. And where your DNA is the mayor and the mayor's staff is are like proteins that are carrying out different functions.
Oh, that's amazing. They look, from what I've seen, kind of like gift wrap. Right, Are there a lot of spirals happening? What are these proteins shaped like?
Ah, that's hilarious. So proteins, proteins are really interesting. They have different shapes and sizes. They fold into these different shapes that determine their functions. But they don't start folded.
Okay, let's back up a little.
We can just start from the beginning, right, we have our DNA, which is inside of our nucleus, and it's very neatly packed and packaged in the nucleus, and it gets read by other proteins right inside of your nucleus into a different code called RNA, which is almost the same as DNA, but it uses a slightly different code. And then the RNA is read by proteins called polymerases, and the polymerases then translate the information from your RNA
to create a protein. As the protein's being made, it's basically like a spaghetti noodle as it comes out of this polimerase, and then as it's coming out, it folds into these different shapes. But the two basic shapes are beta sheets, which kind of look like a brick of ramen noodles, or alpha helises, which are those curly pieces that look like I don't know, RIGATONI actually don't know. Is RIGATONI even the curly one?
I think so, I think so, I think RIGATONI is. I should know. Don't call the warm Italian in the world.
Oh no, it's few silly, few silly.
Okay, you're right, you're totally right.
No, few silly pasta.
I think it's better to know more about molecular biology than pasta. But that's just because I was raised on so much marinera sauce that like, I don't even I can't even like look at pasta we eat so much as a kid, I can relate, yes, just like, oh okay. So then there in those two different beta or alpha helix shapes, and then what do they do from there?
From there, all of these shapes and structures are determined by the protein's amino acid composition, and so depending on the composition of the protein itself, it'll fold and shape into different levels of protein folding. So there's primary structure, secondary structure, tertiary structure, and quaternary structure.
And those different proteins, the complicated ones or the simpler ones, are they bouncing around in our bloodstream to send messages or are they packaged to form different organelles and different organs like what happens to those curly folded, very specific proteins.
I mean, they do so many different things. Where do we even start. They get packaged in the gold gie apparatus and shipped out to different parts of the cells. One place where they can go is they can get packaged out in a vesicle, which is basically just a little you can call it, maybe like a little fat bubble. You know. The proteins can get packaged into vesicles and sent to the cell membrane, where they can release proteins out into the extracellular environment or present the proteins onto
the cell surface. That can be the case for things like antibodies or receptors rather for different channel proteins things like that.
Okay, so right now, no matter what you're doing, there are tiny proteins cruising around your cytosol, which is the ooze that makes up the cytoplasm in your cells, and a gold gie apparatus is sorting some of them and just popping them into fat envelopes. And you just have no idea how hard they're working in trillions of tiny factories, just attaching labels to things and passing chemical notes back and forth like two teenage lovers in an after school detention.
So cells use molecules to communicate. For example, there are certain cell pathways that cause cancer, or there's certain cell pathways that we can study to risk to understand, like cellular responses to immunity, things like that.
And now you have worked in cancer research. You've worked around big vats of E. Coli. You have done like some really awesome work, and obviously you're you're working on a show right now called Nerdy Jobs, which I'm excited about. What was it like studying this, getting your masters and then studying this on a corporate level? What types of things were you looking at? How does the molecular biologists
do their work. Do you need like the most gargantuan microscopes to look at these curly cue proteins out?
Yeah? You do? Really Okay, So I was really lucky, I feel like because the type of work that I was doing was very diverse. I was working at what you call a contract research organization, and that's an organization that big pharmaceutical companies hire out on a contract to
carry out smaller portions of their research. So, for example, like the vaccines that are coming out right now for COVID nineteen, those large pharmaceutical companies could have contracted out portions of their research like asking a lot pay, can we want you to isolate this protein and report back to us about X, Y and z, And then we do that and then we give them the results and that's it. Or they could contract them out for the
entire project. Things like that. The kind of work that I was doing looked a lot different, almost on a weekly basis or monthly basis. Was doing cell transfections, which is a fancy word for running experiments to insert DNA
into cells. Or I was doing crisper projects, or I was trying to generate a new cell line that expresses a particular protein that we're interested in, or isolating DNA from bacteria by the gallons, which is why I had to make, you know, basically gallons of poop, like you just said, because I was using E. Coli as an expression post for the DNA and had to get the DNA out of them. And it was really interesting, you know.
I was working with different types of cell lines, breast cancer cell lines, skin cancer cell lines, and even neurono cell lines, which is really cool. I did some work on trying to understand or find the best drugs to treat Parkinson's disease or brain diseases like Alzheimer's as well, and that involves some really interesting and fun work using neuronal cells.
Neuronal cells side note are types of neurons in the brain. And now when we think of a neuron, you might picture like a kind of hand at the end of a long arm that has a bulbous other end, or maybe it looks like a tree, hence the word dendrite from its root tree. But some research estimates there may be up to a thousand different types of the cells in our nervous system, depending on their structure and function
or location. So okay, My point is our brains don't know everything about our brains, and studying our brains with our brains requires machines devised by our brains to study themselves, which is creepy and also not cheap.
The equipment that we use can is often very expensive. I had the pleasure of working with the super cool machine called the Perkin Elmer Opera.
I think it's called introducing the Opera Phoenix high content screening system from Perkin Elmer. For the speed and sensitivity you need no compromise.
It was super cool because it's a high content screening system. So we were able to test hundreds and thousands of drug compounds on different cell lines to find out, you know, what drugs work the best against a certain type of cancer, and then we would formulate the drug Okay.
Side note, I looked up exactly how expensive this machine is, and I couldn't find a price tag listed anywhere. I was so frustrated. So then I started searching other avenues and I found a twenty eighteen grant proposal asking for the money to acquire such an item, and they were looking for eight hundred and ninety three one hundred and sixty nine nice thousand dollars. Now for that exact price, you can also get a five bedroom, four bath, three
hundred square foot home in Pacific Grove, California. Or you can get two rolls Royce phantoms. Or you can buy an opera house in Phoenix, Arizona, which was purchased in disrepair by the city a few decades ago. Or you can look at sells up close and crunch some numbers and solve some pretty big problems. And so you're just like low key care and cancer when you go into work. How it gets done right, Yeah.
That's the very beginning part of it. Like when you talk about clinical trials, that's where it starts with the molecular biologists trying to find what drugs you should even be looking at in the first place.
And you obviously also are very good at SCOON and you're getting your PhD in science communication itself. What does that work?
Like? This work is so different. Yeah, it's so different. And I want to say, like, I feel like my PhD would have been a little less painful had I really understood and been trained with the social sciences background. But I also love it at the same time because I feel like I've truly mastered how to think like a stem scientist, and now I'm mastering how to think like a social scientist. And I feel like I have a whole complete brain. It's really cool.
Well, I imagine getting your PhD in science communication when you already are responsible for like huge viral hits and you have a great following. Are you finding that in the course of getting your PhD you're acting more and more as a mentor to the people in the program around you?
You know, It's it's really interesting. Not really my PhDs in science education and a lot of the people that are in my program aren't doing the same work that I'm doing at all. I feel like I'm the only person who might have ever even focused on science communication itself. A lot of the work that other folks are doing, are in the K twelve space and truly centered in the classroom, which is fine, but when we come together and talk about our research, it definitely looks a lot different.
So not only will she be getting that PhD very soon, but she's also working on a few academic papers about science communication and how vital it is for scientists to share the work they've done with the public. But how does one calm sigh? What are they learning to help teach others, how to teach others brains on brains on brains.
I think that I can talk about one of the things that really made my light bulb blow off that I learned as a graduate student in education, and this was an example that was given in I believe the books called How People Learn, and there was an example given in the book about how people from different like
environments physical environments interpret information differently. The example that they gave was a very literal one where they described a study where they showed a set of pictures to people who lived in a very rural flat lands environment and then that same picture to people who lived in an urban environment with skyscrapers and tall buildings, and they found that people from rural environments interpret vertical lines differently than
people who live in urban environments that have tall buildings in skyscrapers.
Oh my gosh.
Yeah. So, I mean, when you think about that simple thing, people interpreting lines differently and shapes differently based on how where they live and where they come from, you can only imagine all of the complexities that exist from person
to person based on their upbringing, their personal experience. So I try to be very mindful when I'm educating someone that not only am I trying to teach them something, but I, in the same space, should be trying to learn as much about that person as possible so that I know how to teach them, or so that I can understand how they might be interpreting my information.
And now, whether it's one on one or via a huge viral video, as a communicator, it's important to know your audience right and cater a little to what will affect them most powerfully. But how does she do that while staying true to herself and the art that she wants to make. You have such a distinct voice, and you have such a magnetic vibe when it comes to psychom How did you find your voice?
In it. I love this ques question because it points me to a very specific moment in my life where I actively made this decision to exist as I am in any space that I occupied, but especially as a scientist. And this moment happened when I was, I believe, a junior in college. I had started my first, very first
undergraduate research experience. And this is important for a lot of junior scientists because it's quite often, you know, in college, we have our first formal research project where we have a hypothesis and we're actually using things around us to collect data, and it's a long term thing that takes months and months, and it's a pretty big deal, you know,
just when you're just starting out. My study was about understanding soil microbial respiration, and that's really fancy term for how do the germs in the dirt produce gas and how much gas. So my experiments, I was taking dirt and putting it into a closed chamber, and the chamber had a measurement device on it that would tell me how much carbon dioxide, what different gas levels were emanating
from the dirt itself. On a bigger scale, things like global warming or flooding impact how microbes in the soil produce gas. So that was my research project. And so I was doing this independently. I was a junior in college. I had an advisor and I'd go in the lab every day collect my data, you know, X, Y, and Z. So this took me months. At the end of semester two, my advisor says, Raven, you've been working so hard on all of this. You have great data. I think that
you would be a great presenter at the undergraduate research symposium. Yeah. I know, and so it's a pretty big deal. And so for like those of you who don't know what that is and you're listening, it's basically you get a chance to put your data and your research onto a poster. In this case, it was a poster symposium, and all of the scientists line up. They form aisles in a big room and you can walk around through the aisles and ask scientists questions about their research. And so that's
what I was going to be doing. And so my advisor says, you know, this is what needs to be on your poster. He explains, you know, how the data should look, etc. Right, he didn't really explain too much to me. All I really knew was that I had to make a poster with my research on it. And I'm like, great, I worked so hard for this, Like, yeah, let's do this. I can't wait now, mind you. I'm a junior in college. The last time I had made a poster about anything was probably in middle school when
I won an inventor's contest. It was called the Invention Convention, and I won third place, and my third place it was Barbie Barbie's fishing row, and it was a Barbie that had a boat that fished for her so she could look cute in the boat. I love this, So she could look cute in the boat. So I had like the Barbie she was like in pumps and sequins and stuff in this pink boat and the boat was fishing for her, so like she could kick back with her little water bottle and like just chill out in
the ocean, you know whatever. I won third place. My poster had sequins on it, glitter stickers like Pokemon cards, like, it was a really intense poster. So we're fast forward back from from middle school to college. I'm like, hell, yeah, I get to make another poster, right, Oh my god. So I go to the craft store. And now I have big girl money. Okay, I'm in college, right, I've got I'm not in middle school. I've got dollar I've got twenty dollars bills and stuff. Right. So I'm at
the craft store. My cart is overflowing with feathers, glitters, stickers, stamps, gosh, different types of scrapbook paper, glue, I mean anything, ribbons, everything, everything, And I just I was so proud. I lugged all of that stuff into my dorm room and I go to town making my poster m hm. And my advisor gave me a poster tube because he told me, put your poster in it, and like, roll your poster up, put it in the tube so it stays nice for
your symposium. So I finished making my poster with all of literally all of the things I just described that, we're in my cart at the craft store, and he says, I want to check your poster before the symposium tomorrow. Now we're like the day before the symposium. I'm like sure, Now I should probably explain what a poster is supposed
to look like. Normally, posters for research conferences are generally it's generally just paper, Okay, just paper and and one color of ink usually and in times New Roman, like the most plain font you could ever think of, about maybe three hundred to five words total, maybe a couple of pictures, a graph, your references. I mean, it's just bare minimum period. Okay. So I come to my advisor's office and he's like, okay, let's see your poster excited
for tomorrow. I take my poster out the two and you know how like when you glue glitter on this stuff, it doesn't really stay on. It kind of like falls up. So I'm unrolling the poster and there's like chunks of glitter falling out and like feathers collapsing to the floor and like it's all crinkly and stuff. And he's like, oh my god, oh my god. More absolutely mortified. I've never seen anybody so disappointed in my entire life, even in my adult life. Okay, this is the most disappointed,
the most disappointment I've ever caused. So he says, not only oh my god, I can't believe, Wow, what am I looking at, but also he said two things. You can either go home and redo this. And he explained to me that you know the reason why he gave me the poster tube was because he thought that I was going to go to the printing office and have my poster printed, and that I was going to pick it up from the printing office and put in the tube. He was like, that's why I gave you the poster
the tube. And he's like, you can either go home and do this really quick and you might be able to get it too the printer's office and do this the right way, like the plane way, or you cannot go to the conference at all. No, I know, right, no. And his reasoning was that he felt like people were going to laugh at me. Didn't He didn't want me to be embarrassed. He was like, everybody's gonna laugh at you. This is like you know, this is this is a no.
It's a no for me. Dog it's dog. And I was like, hmm.
Yeah.
I was like wow, I had to I had to take a moment, you know, like this was somebody that I respected telling me this, somebody you know, who has a PhD in the field and has earned their stripes well before I was ever gonna earn my stripes. And I'm like, you know, if this is how this is supposed to go, that's I get it, you know. But I also had to sit with the fact that I really enjoyed making that poster. Yeah, I had spent all night.
I was so excited, you know, and I felt like I had really put my entire self into making it and that it was really representative of who I was as a person. And I also had to sit with the fact that the whole point of going to the symposium was to present my research, and that my research was going to be the same regardless of whether I remade my poster or not. So I did not redo my poster. I actually went to the symposium with the glitter poster. Yes, Yes, it went amazing. So everyone, like
I said before symposium, everybody's standing in a line. We form aisles, and we're all standing next to each other with these posters on a stand, waiting for people to talk to us about our research. And I had people lining up to talk to me. Ya literally, I love it lining up. Nobody laughed at me to my face. People were very inspired to see my poster, and they were excited to ask me questions about my research. And not only that I actually won an award. Yeah, I
won an award for my research. Yeah, Oh my god. It was a student excellence award and it was because of my research. It had nothing to do with how my poster looked. It was just excellence in research and student research. And that was a very important moment for me. And it's a really simple story, but I was able to go back to my advisor and I kind of rubbed it in his face a little bit, yeah, because he didn't know that I was going to do that.
And I said, look, I got an award. I got an award for this, And you said people were gonna laugh at me. And I just learned from that point on, don't sometimes you don't listen to people when they tell you no. You know, sometimes no, Actually it's like yes a lot of times it actually does me no, So like, don't take me out of context. But when people are denying you an opportunity to be yourself in a space where you belong just as you are are, you don't
have to take that denial. You can say no to that and come as you are and nobody gets hurt. In fact, people were coming up to me at the conference business majors, music majors, etc. Saying this makes me want to take a science class. Oh yeah, it's like, what major are you that you get to do this stuff? Like, this is so cool that you get to do this. It was inspiring to people even outside of my own field. So I try to carry that energy with me today,
which is probably very obvious. Now. I don't know that you heard this story, but I just can't live in a space where somebody's gonna tell me that I can't bring my glitter poster to the conference, you know.
Oh my gosh, I love this so much. Do you have pictures of it?
I wish I did. I really wish I did. I was. It was such a long time ago, and I think I was just too scared to take a picture of it. But the glitter never left. I literally can't get rid of that. Glitterates everywhere.
Still, it's in your soul and you know, under the baseboards and stuff. I love it. Yeah, Oh, that's so inspiring that it's okay to be more yourself than you think, you know, to show up with your whole self.
It is. It's a little scary, but it never It's never a bad thing to just embrace, embrace who you are inside. It's just never a bad thing. And once you kind of get past that fear of what do other people think? Are people going to laugh at me? Which they might, And that's fine. It's just the world is yours. Just go go do it, do it scared.
I love it as a person who has struggled with being scared to start making something important to me. I had to mine her for self help strategies because I am in information leech and that is my deal. Your videos are incredible and they have explained so much great stuff. How do you know what you're gonna make a video about? How do you start writing it? Where does the music come from?
Usually it's a situation where inspiration just strikes me and I lock myself in a room for about twenty minutes and outcomes a song. I don't think people really realize how quick the process is for me, and it's it's often so quick that I don't know my own lyrics, and you, like, if you look at my videos closely, you'll see like, as I'm lip syncing, I actually miss
a lot of the words. I don't know what I'm saying because I wrote the song in like three seconds, and then I'm trying to record it on a video and I don't remember what I just said. Also, I have ADHD, so that's probably a part of it. But yeah, it's a really quick process.
Do you decide when you are writing it kind of what the video is going to look like or do you just film a bunch of stuff and it comes together in the edit.
Well, because we're in a pandemic, and most of the work that I've done at this point has been during a pandemic, I have limited resources. You know. I can't go out to places like inside of the lab to film fun things. It's there's two feet of snow on the ground right now, Like I can't really go outside. So I just work with what I have and try to use my personality and my presence to add certain
dimensions to what I'm doing. But my partner, you know, he he already knows, Like once I make a song, he's already committed, whether he likes it or not, to like helping with the music video, He's like, all right, she's got a song. What angle do I need to hold the camera? Like all right? He loves it though, he's just he's a he's a huge introvert, but he likes to be on the other side of the camera.
And you two are now married. You met at math camp?
Correct, we did meet at math camp.
Yes' story just two hot nerds meeting at math camp getting married like a decade later.
I know. I honestly like didn't give him the time of day when we first met because he was so quiet, you know, and I have a lot of personality, so he didn't really stick out to me then. He was just the quiet hot guy. I'm like, we love each other very much. He has a Twitter account now where he teases me relentlessly, so yeah, he's shy but behind a little fake account. Yeah, he says a lot.
That's mister science maven.
Right. Yeah.
Yeah, And you touched on a little bit that you have ADHD, and I wanted to ask about how you have learned maybe workarounds or things that work for how your brain works. So anything that you've learned that you wish that you knew earlier.
I think that you really do have to give yourself grace and just understand that your brain simply does not operate how most people's brains work, and it's not your fault. You know that you do things maybe a little bit slower than other people because you need just a little bit of extra time to process, or maybe you might get distracted unfortunately or off task. Just have grace with yourself and understand it's not really a deficit. It's just a different type of life that you're meant to live,
and it couldn't be your superpower. I love trying to figure out new ways to accommodate myself and give myself grace. Like, for example, if I had a meeting or something where I've had to concentrate for a long time, I like to just give myself grace and say, you know what, you worked really hard to focus and stay still for this meeting. If you want to pig out, you know, or just be a goofball for the rest of the day, do that like you earned that, that's okay. If you
can't handle anymore, that's also okay. And also asking for help when I need it has been a really big thing, especially this past year, and there's no one size fits all answer for everybody. But I do think that that knowledge is power and sharing information is the best thing that we can do.
I have so many questions from patrons. Can I just lobs at you oo?
Yes?
Okay, but before we Pepper her with curiosities. We will, of course donate to a cause of the ologists choosing, and Raven said she didn't have a preference, She just liked the money to go to whomever needs it. And as it happened, our mutual buddy Hank Green's Project for Awesome was this past weekend, so we made a donation in Raven's name, which happened to be at the final couple of seconds as they reached the two million dollar mark, I logged on and they were a few hundred dollars short,
so we made it happen. Project for Awesome is a project of the Foundation to decrease world suck, and you can learn more about them at projectfoawesome dot com. And that donation was made possible by sponsors of the show, whom I shall now yammer about very briefly. Okay, you had questions for Raven, but in addition to the questions, you had praise and compliments in general fawning, I loved it before I read you questions. Kelsey Napa says, holy crap, I love her.
Yeah, I love you too, Kelsey.
Crystal Hakka just says, Raven the science Maven and all caps answered Jonah Hill squealing and hand flailing.
Chiff Here.
Alanda Cole says, Hi, Raven, I'm a huge fan. I have no specific question, just saying that I just can't. Yeah, I love it. Florence Jan says Raven, I follow you on Twitter and I'm a big fan. Seb Kencino says, Hi, Raven, I love how you illuminate Twitter. So yeah, just a lot of messages saying all caps squealing because they are very people that are very excited that you're on.
The feeling is mutual. Thanks every joting me. A lot of.
Folks had questions, including I'm Brandon Butler and Ashley Emmanuel. Is mitochondria actually the powerhouse of the cell? What is the mitochondria doing? Lah?
So, yeah, it definitely is the mitochondria of eukaryotic cells, meaning not bacteria basically. And what mitochondria do is they break down sugars and turn them into energy.
It's almost like something that breaks down gasoline in our car.
Honestly, yeah, it's pretty much.
Okay, I look this up and wouldn't you know it, Molecular biology happens to be a little bit more complicated than a Honda civic engine. But still mitochondria do sort of burn our food fuel and produce a source of energy. This whole process is called oxidative phosphorylation, and it does require oxygen, just like a combustion engine. Also, there can
be a bunch of mitochondria shoved into one cell. The swimmy sperm have mitochondria that run in a spiral down as flappy floppy tail, kind of like ribbons on a really horny maypole. Your hard working heart muscles right now are really jam packed with mitochondria. So yes, mitochondria is the powerhouse of the cell. It is useful information to know if you're into breathing and being alive and stuff. Now, as long as we are gossiping about spiral structures, let's
get into the heroic helix, shall we. Keana Spinelli asks, I was told several times when I was younger that there were six plus feet of a DNA strand in just one cell. Is this true or is that flim flam?
Oh my gosh. So I don't know the exact answer to this, but I would not be surprised because DNA is super coiled inside of your nucleus. I mean, it's It doesn't just hang out and there like spaghetti. It's wrapped around itself. It's wrapped around things called histones, and it's very tightly and neatly packaged inside of your nucleus. So I wouldn't be surprised if you stretched it all out that it did that it did end up being six feet or six and a half feet.
Okay, I was so curious. I had to double check this, and geneticist doctor Barry Starr does confirm that it's about six feet or two meters of DNA strands inside each cell, and then he calculated that each human being has around ten billion miles of DNA in them, meaning that your DNA your DNA right now, just as you're sitting here eating pirate's booty or whatever, your DNA could stretch to the Sun and back. What you, beautiful freak, You just
living pooping work of magic, all of us. I have a ton of questions, and I will list all of the people who asked about it, because it is numerous. Okay,
deep breath, I'm looking at you, patrons. Eric Pahanka, Gabriel Stern, Austin Davis Bourne, Colin, Mike Monoikowski, Anna Goosman, Alanda Cole, Adele Maisonneve, Mattie Reeves, Morgan, Alexander Coburn, Seth Succi, Bennett Gerber, and Jen Squirrel Alvarez, as well as first time question askers Katie Willis, Melanie Lee and Nano Naturalist who called them foldy boys, and Jizle Balpazar Carazone, who wrote in specifically this question just tickled me. So I'm reading you.
But as far as I understand it, a preon disease is due to a fucked up protein which fucks up unfucked up proteins when they end. Is it possible to engineer a beneficial preon or whatever, like a blessed protein saundering around blessing the unenlightened common proats that's what they're called now, so that they can work more effectively, efficiently and blessedly inside our disgusting sacks of disappointment and gore. How superheroes are made the preonic man, we have the technology.
A lot of.
People asked how terrified should I be about preon diseases? Davis Board asks, please tell us everything about all caps preons. I hope I'm saying it prions because I've I've read that it's preons or prions, and I get very self conscious about how it stand.
Yeah, I've said prior. Okay, you know I'm not saying I'm not saying prion to correct you. It's just let's just cover all of our bases here. So yes, hypothetically that would be it would be possible for us to create a prion that that can do this, But I don't think that we even have a good enough understanding of protein folding at this point to do that, Like we just I'm not sure if you caught what what's happened recently with the alpha fold.
Yes, we have so many questions about that. Oh you do alpha side note was developed by Google's deep Mind, and this AI program ranked number one multiple times on predicting protein folding structures. Its last victory and such a competition was back in November, and it yielded results that scientists called astounding. Everyone lost their shit about this for
good reason. It was nuts, and a lot of people asked about it, including Hudson Ansley, Adam Drake, Jamie Jensen, and then Sam Kilgore, who phrased it, how excited are you about deep Mind's protein folding AI on a scale from ferry to OMFG.
Well, basically, I should say that my entire master's degree is about protein folding. And I spent two and a half years characterizing the structure and the function of a chaperone protein, which is a protein that helps other proteins fold. It took me two and a half years to just do that, to look at the sequence and understand based on this, based on these amino acids, this is how
this chaperone protein should fold. The alpha fold alpha fold program can probably take the same information and do it
in less than a minute, if not seconds. Oh my god, So we within you know, I want to say, just a handful of years, we've been able to make this advancement in technology, and this advancement and having AI help us understand how proteins fold and make those predictions will help us to understand how proteins interact with each other because there are a lot of a lot of pathways, meaning you know, chains of reaction where things are interacting with other things in the Celler's a lot of pathways
that we are still trying to figure out. So it's very possible that we could make a protein do assist with prion diseases, but we haven't figured out really the basics. Yeah, but technology is very promising and helping us do that.
So how do these prion preon diseases even start. I want to say that they are the work of a tiny microscopic or a gommi goblin, but is that true?
Yeah, so prions, there are misfolded proteins proteins they are when they come out of the ribosome as they're being made. They're folding based on their amino acid sequence. But there's also a lot of other checkpoints that are happening in that process that is acting as a safeguard to make sure that that protein's being folded properly. So we have other proteins that are called chaperone proteins, and literally they
are helping the protein fold into its correct shape. And the protein shape determines its function, so to fold the exact right way so that it can do its job. When that doesn't happen the right way, it can cause disease. Some things that can happen are when the proteins are misfolded, they can accumulate together, they can stick together, they're affecting other variants of the same protein and causing them to misfold. So it's something that you really don't want to happen. Yeah,
and mad cow disease is one of them. There's quite a few of them. I don't know them all because this is like a very small subset. It's a really interesting area. I think proteins are so interesting.
So a few tiny tidbits. Priyon comes from the portmanteau of the words protonacious, infectious particle. And I just read that the scientist who coined the phrase wat and it pronounced predon, So we may have a real jift gift sitch here. Please do not write to me. I don't
want to hear it. So, according to a twenty nineteen Seminars in Neurology article, preon diseases share the commonality and preon diseases share the commonality of abnormally shaped proteins that resist being broken down by heat, even extreme heat, and by chemicals like proteases. So there are a few variations. There's sporadic, genetic and acquired. But don't freak out too hard though. Preon disease is still pretty rare, with about three hundred and fifty cases happening in the US per year.
My main advice is just try not to eat a lot of brains. Isn't that helpful? Also, if you're worried about chronic wasting disease, which is spreading in deer populations in the United States, there's some info on that in the Cervidology episodes I did in September about deer. But let's talk about cuter things like little ABT proteins with legs, marching a molecule down a path. You mentioned also chaperone protein.
Someone Jacob Elsbury asked, how accurate is that viral Jeff of a cute little Kinesian protein trotting around the cell carrying a giant backpack of what I'm assuming it's more protein. Is that at all accurate?
It's accurate, But the reality is that it is not walking that slowly at all. Like, oh no, those little bad boys, whatever bad things, the little bad things, they are zipping across like faster than you can even blink. So that's the only real difference there. I mean, obviously it's not gonna be that cute.
That little thing is so cute.
Yeah, he's running, he's running for his life.
A few people asked about motor proteins. Honey wants to know. Can you tell us about motor proteins. How the heck do they work?
Ah? So, the little guy walking is a motor protein and they carry cargo. Basically, the cargo go that are containing molecules, proteins, whatever it could be. Anything it could be. They could be carrying organelles, they can carry different structures within the cell. They can move chromosomes. They're just they're working hard. Okay, they're working hard, and they move in particular ways. Think of this as a highway, and one end of the highway is a negative side and the
other side is positive. Dininge walks towards the negative end, and they're carrying their cargo from the peripheral side of the cell to the center of the cell. And then Keynesin is like Dinine's sister, and they are walking in the opposite direction. So they're walking towards the positive side, and they carry their cargo from the center of the
cell to the periphery of the cell. So in order to move their little feet, they use ATP, which is the energy currency of the cell, which comes from the mitochondria. So now we've come full circle back to the mitochondria. They're going so fast.
John Sanson has a question about where did DNA even come from? Like how did random bits of atoms and molecules know to build themselves into proteins and then assemble into DNA strands which now tell other things to build other DNA strands.
This is something that I think about too much and it freaks me out. My brain is melting. But let's look great. That's that's a question about the origin of life, because all living organisms on Earth use DNA to generate their life process, and we don't necessarily know exactly how this all started, and this will be a question that we're we are likely trying to answer for many, many years to come. But I love thinking about it because of all the possibilities.
So for years, the hypothesis has been that DNA started with the simpler single strand RNA, But in the past decade or so, other scientists are just begging to differ and say that DNA, which kind of has a trickier sugar molecule as well as that double helix shape, could have arisen at the same time. It's even possible that a hybrid RNA DNA molecule first arose and then split off into two forms. Who's to know if you have
a time machine, let us know. Now. One thing we are sure about is that these replicated codes have been encased in cellular goo and structures for billions of years. Billions with a B plus. In all this talk about DNA, I wanted to know if Raven has any feelings about Watson, Crick and Franklin. Is that something that ever gets her goat?
Oh it does. It's funny because I'm actually on the Rosalind Franklin the Society's advisory boards, so shout out to shout out to Rosalind Franklin. But yeah, the way that I learned the story was that Rosalind Franklin, there were several scientists working at the same time to understand the structure of DNA, and my understanding is that Rosalind, Franklin, Watson, and Krik were all scientists who were They weren't working together.
Rosalind Franklin was working separately than the others, but the two guys Watson and Krik made a visit to Rosalind's lab as she was doing similar work and stole some of her information so that they could further their own findings and ultimately win a Nobel price for it. So there's that.
Yeah, okay, a few people Katrina nujen Adele Davis Bourne epigenetics. What's going on? How does it change DNA expression and pass it on to the next generation? Katrina ask will my children have my same weird quirks and habits?
This is really interesting and something that I wish I had spent more time on when I was on my genetics cake. But epigenetics it's a part of molecular bio that's looking at heredity, but not heredity that's caused by actual alterations in DNA itself. Right, the DNA has a code, and that set of code again codes for proteins and protein products. But epigenetics it's like they are changes on the DNA, like literally on it. But it's really cool. It's a different way of looking at heredity.
So for a very very quick primer on epigenetics, your DNA is a big ass long coat, kind of like a recipe or an ingredients list, and that double helix is like a big old long scroll, just meters of it right in each cell. So how does a cell with all the instructions for all the other cells know to be a heart cell or groamy one, bristly mustache hair or line my guts. So certain genes are turned on or off by signals or even proteins according to
the function of the cell. But the proteins can also turn on and off other expressions of the cell in response to environmental factors and then replicate from there, and that is called your epigenome. Now, speaking of hearts, many patrons wanted to know what was closest to Ravens and Katie matt Sicato, Earl of Graymulkin, Kathleen sachs, Ira Gray, and Ashley Emmanuel all had favorite questions essentially favorite type of cell or protein or organelle or nitrogenous base, just
normal questions you'd ask. Really any celeb. George Powell wants to note, what's your favorite protein?
Oh, you know what, that's a really good question. I personally am fascinated by how people name proteins. There is a protein called the pokemon protein. What. Yeah, There's a protein called sonic hedgehog, which is actually a critical gene involved in human development. And there's a nemo one. There's a cannon Barbie protein. There's scramblease, which is an enzyme that scrambles phospholipids between the inside and the outside of
this a cell membrane. There's pikachuran protein. There's spock one that's in zebrafish and it causes the fish to develop like pointy ears like spock.
No, yeah, I mean earl of Gramblekin asked do you have a favorite protein or protein name? And I had no idea why. They asked about the name. Who gets to name these?
The scientists that discover them get to name them.
Oh, my gosh, A lot of animation fans apparently.
Yeah, yeah, I mean these these are They're really funny.
Obviously, there's so many things that must be difficult about trying to wrap your brain around these tiny rotein structures. But what is the most difficult thing about being a molecular biologist who is also a science communicator, who is also responsible for teaching so many people about very complicated topics, Like, what's the hardest part about it?
Oh, the hardest part about what I do? Uh, that's
a good one. Let's see. Hmm. I think that maybe the hardest part of what I do is it's also one of the most important things that I that I do, and I know, although it's hard, I really do try my best, and that is to always just make sure that you're communicating accurate information because oftentimes people they may not necessarily go to directly to the source for their primary understanding of what's going on in the science world, and they're looking at people like me or going on
social media to get their information. And it's just so important that although what we do is fun and it's meant to be friendly and approachable, that we're always focused on giving as accurate, if information as possible. And I'm very careful to only speak on things that I feel like I'm truly an expert in, and if I'm not an expert in it, I definitely point people to a recon source, a person who is an expert, or I find very basic information and try to translate that the
best way that I can. But I definitely think that it's important to always be accurate first and then be engaging second. You can do those things at the same time, but definitely not one without the other.
Do you have any advice for anyone who is going into molecular biology or science communication, or things that if you had a time machine you could go back and pep talk yourself about.
You know, I think that maybe one of the biggest pieces of advice I would say for somebody who's interested in doing both of those things, make sure that you're applying to programs that will support you in both of
your interests. There are programs that exist, they seem to be very few, but just keep an eye out for programs that can support your interest in being a scientist who wants to communicate and who has a desire to be a public facing information source, and look out for programs that have opportunities for you to learn how to be the best communicator and the best scientist at the
same time. Try not to sacrifice your interests. There are a lot of times that I've heard people who are interested in being a scientist and an educator often have to choose between the two when they're looking to enroll in programs. But it doesn't have to be the case. So definitely look hard and make sure you find your home that's going to be good for you and will serve your best interest.
And what about the thing you love the most about what you do.
I truly love building community, and I think that because I am who I am, I tend to build communities that are very diverse because I show a lot of different sides of myself that I feel like people from different walks of life and different backgrounds can relate to.
And I try to be very transparent about who I am and what I'm interested in and what I'm passionate about, so that people who even aren't in science can latch onto something about a scientist that they see and maybe be more willing to listen and learn about science because they do relate. And I also love bringing these communities together in conversations about important things and watching people in my community learn from each other and teach each other.
That's probably the best thing that I enjoy about what I do.
You have a lot of projects guard going on. Is there anything that we should be looking out for, anything that you're working on that you're really excited about?
Yes, I am. I'm always working on new things. That's one of the awesome parts about having ADHD. And I think a lot of people are like, how do you do so many things at once? I have help. I have people around me who want to see me succeed and try to step in where they can to make sure that everything runs relatively smoothly. But one of my most exciting things that I'm working on is my new fashion line, Smarty Pants. And Smarty Pants is really what
I've always wanted to do for the STEM community. I've always wanted to give something to people that they could wear that expressed their sense of belonging in the field and their desire to be seen for both the brilliance that they have inside and also make that shine from
within to the outside. And so it's it's really meant to be clothes that empower you as you go on about your everyday work in STEM and beyond, because it's really not just for STEM professionals, just for anybody who supports STEM, enjoys learning about STEM, or somebody who identifies as a smarty Pants mm hmm.
It's just it's really infectious the way that you communicate your science. So I'm excited to call you doctor Baxter. When I know any idea timeline on that, when we can pop all the champagne in the world ever, that would.
Be late April, I will be doctor Raven the science maven Ah. That's so exciting. It sounds nake.
It's amazing. I'm so excited for you. Do you know how you're gonna celebrate?
I want to throw a party, but we'll see. I just want everybody who's who's happy for me to also have the chance to sell right. So I'm thinking maybe an online Shenanigan, Yeah, like a I don't know. I'm thinking a disco party. Yes, please?
So ask smart Maven's very simple, shameless questions. Because you only live once, and maybe your molecules may get rebuilt and refolded into proteins and become a frog. But why not learn while you're alive and a person.

That's linked in the show notes as well. Thank you Noel Dilworth aka the Best, who helps me manage all my scheduling. Because inside my skull is just one steaming scoop of chili, it doesn't always get the job done. So thank you also to Jared Sleeper who assistant edits and does so much more like he just grabbed me a bag of carab chips to snack on, no joke,
and I like them. And also to the glitter on our poster, Stephen Ray Morris, who now hosts three podcasts see Jurassicwright, The per Cast, and Everything but the Movie, a Star Wars Books podcast. Nick Thorburn wrote and performed the theme music. He is in a band called Islands, which is a very good band, and if you listen through the credits to celebrate those people, then I also tell you a secret at the end of the episode
this week. Okay, so we're getting some work done in the yard and it involves poored concrete, and I feel really awful because I learned after that concrete is terrible for the environment and carbon emissions. And then that led me down a path of using stone stacking to build some other stuff in the yard. And I found out there are these free rocks you can get literally by the ton, almost anywhere, and sometimes people will deliver them for free. And the stone is called urbanite, and it's
just broken up concrete. It's just straight up junk that they would throw away, but you can get it for free and you could build stuff with it. So look up urbanite like walls and stuff. Pretty cool. It looks kind of awesome. It looks like old stone walls, a little craggy. Anyway, Urbanite it's a thing, and if you're looking for it, you can just check Craigslist under the free section for free concrete or urbanite. Some people are
already hip to the name. And I realized just now that in telling you the secret, maybe this might help me atone for my concrete use before I knew any better. So just go on craig list and look for free concrete or urbanite. Pinarest the hell out of it. And let's try to use more of that and less concrete. Okay, A bright Pacadermatology, hobbiology, r doo, zoology, lithology, new technology, meteorology, metatology, menthology, seriology, selenology
