The four basic categories of molecules for building life are carbohydrates, lipids, proteins, and nucleic acids.
Carbohydrates serve many purposes, from energy to structure to chemical communication, as monomers or polymers.
Lipids, which are hydrophobic, also have different purposes, including energy storage, structure, and signaling.
Proteins, made of amino acids in up to four structural levels, are involved in just about every process of life.
The nucleic acids DNA and RNA consist of four nucleotide building blocks, and each has different purposes.
The longer version
Life is so diverse and unwieldy, it may surprise you to learn that we can break it down into four basic categories of molecules. Possibly even more implausible is the fact that two of these categories of large molecules themselves break down into a surprisingly small number of building blocks. The proteins that make up all of the living things on this planet and ensure their appropriate structure and smooth function consist of only 20 different kinds of building blocks. Nucleic acids, specifically DNA, are even more basic: only four different kinds of molecules provide the materials to build the countless different genetic codes that translate into all the different walking, swimming, crawling, oozing, and/or photosynthesizing organisms that populate the third rock from the Sun.
Big Molecules with Small Building Blocks
The functional groups, assembled into building blocks on backbones of carbon atoms, can be bonded together to yield large molecules that we classify into four basic categories. These molecules, in many different permutations, are the basis for the diversity that we see among living things. They can consist of thousands of atoms, but only a handful of different kinds of atoms form them. It’s like building apartment buildings using a small selection of different materials: bricks, mortar, iron, glass, and wood. Arranged in different ways, these few materials can yield a huge variety of structures.
We encountered functional groups and the SPHONC in Chapter 3. These components form the four categories of molecules of life. These Big Four biological molecules are carbohydrates, lipids, proteins, and nucleic acids. They can have many roles, from giving an organism structure to being involved in one of the millions of processes of living. Let’s meet each category individually and discover the basic roles of each in the structure and function of life.
You have met carbohydrates before, whether you know it or not. We refer to them casually as “sugars,” molecules made of carbon, hydrogen, and oxygen. A sugar molecule has a carbon backbone, usually five or six carbons in the ones we’ll discuss here, but it can be as few as three. Sugar molecules can link together in pairs or in chains or branching “trees,” either for structure or energy storage.
When you look on a nutrition label, you’ll see reference to “sugars.” That term includes carbohydrates that provide energy, which we get from breaking the chemical bonds in a sugar called glucose. The “sugars” on a nutrition label also include those that give structure to a plant, which we call fiber. Both are important nutrients for people.
Sugars serve many purposes. They give crunch to the cell walls of a plant or the exoskeleton of a beetle and chemical energy to the marathon runner. When attached to other molecules, like proteins or fats, they aid in communication between cells. But before we get any further into their uses, let’s talk structure.
The sugars we encounter most in basic biology have their five or six carbons linked together in a ring. There’s no need to dive deep into organic chemistry, but there are a couple of essential things to know to interpret the standard representations of these molecules.
Check out the sugars depicted in the figure. The top-left molecule, glucose, has six carbons, which have been numbered. The sugar to its right is the same glucose, with all but one “C” removed. The other five carbons are still there but are inferred using the conventions of organic chemistry: Anywhere there is a corner, there’s a carbon unless otherwise indicated. It might be a good exercise for you to add in a “C” over each corner so that you gain a good understanding of this convention. You should end up adding in five carbon symbols; the sixth is already given because that is conventionally included when it occurs outside of the ring.
On the left is a glucose with all of its carbons indicated. They’re also numbered, which is important to understand now for information that comes later. On the right is the same molecule, glucose, without the carbons indicated (except for the sixth one). Wherever there is a corner, there is a carbon, unless otherwise indicated (as with the oxygen). On the bottom left is ribose, the sugar found in RNA. The sugar on the bottom right is deoxyribose. Note that at carbon 2 (*), the ribose and deoxyribose differ by a single oxygen.
The lower left sugar in the figure is a ribose. In this depiction, the carbons, except the one outside of the ring, have not been drawn in, and they are not numbered. This is the standard way sugars are presented in texts. Can you tell how many carbons there are in this sugar? Count the corners and don’t forget the one that’s already indicated!
If you said “five,” you are right. Ribose is a pentose (pent = five) and happens to be the sugar present in ribonucleic acid, or RNA. Think to yourself what the sugar might be in deoxyribonucleic acid, or DNA. If you thought, deoxyribose, you’d be right.
The fourth sugar given in the figure is a deoxyribose. In organic chemistry, it’s not enough to know that corners indicate carbons. Each carbon also has a specific number, which becomes important in discussions of nucleic acids. Luckily, we get to keep our carbon counting pretty simple in basic biology. To count carbons, you start with the carbon to the right of the non-carbon corner of the molecule. The deoxyribose or ribose always looks to me like a little cupcake with a cherry on top. The “cherry” is an oxygen. To the right of that oxygen, we start counting carbons, so that corner to the right of the “cherry” is the first carbon. Now, keep counting. Here’s a little test: What is hanging down from carbon 2 of the deoxyribose?
If you said a hydrogen (H), you are right! Now, compare the deoxyribose to the ribose. Do you see the difference in what hangs off of the carbon 2 of each sugar? You’ll see that the carbon 2 of ribose has an –OH, rather than an H. The reason the deoxyribose is called that is because the O on the second carbon of the ribose has been removed, leaving a “deoxyed” ribose. This tiny distinction between the sugars used in DNA and RNA is significant enough in biology that we use it to distinguish the two nucleic acids.
In fact, these subtle differences in sugars mean big differences for many biological molecules. Below, you’ll find a couple of ways that apparently small changes in a sugar molecule can mean big changes in what it does. These little changes make the difference between a delicious sugar cookie and the crunchy exoskeleton of a dung beetle.
Sugar and Fuel
A marathon runner keeps fuel on hand in the form of “carbs,” or sugars. These fuels provide the marathoner’s straining body with the energy it needs to keep the muscles pumping. When we take in sugar like this, it often comes in the form of glucose molecules attached together in a polymer called starch. We are especially equipped to start breaking off individual glucose molecules the minute we start chewing on a starch.
Double X Extra: A monomer is a building block (mono = one) and a polymer is a chain of monomers. With a few dozen monomers or building blocks, we get millions of different polymers. That may sound nutty until you think of the infinity of values that can be built using only the numbers 0 through 9 as building blocks or the intricate programming that is done using only a binary code of zeros and ones in different combinations.
Our bodies then can rapidly take the single molecules, or monomers, into cells and crack open the chemical bonds to transform the energy for use. The bonds of a sugar are packed with chemical energy that we capture to build a different kind of energy-containing molecule that our muscles access easily. Most species rely on this process of capturing energy from sugars and transforming it for specific purposes.
Polysaccharides: Fuel and Form
Plants use the Sun’s energy to make their own glucose, and starch is actually a plant’s way of storing up that sugar. Potatoes, for example, are quite good at packing away tons of glucose molecules and are known to dieticians as a “starchy” vegetable. The glucose molecules in starch are packed fairly closely together. A string of sugar molecules bonded together through dehydration synthesis, as they are in starch, is a polymer called a polysaccharide (poly = many; saccharide = sugar). When the monomers of the polysaccharide are released, as when our bodies break them up, the reaction that releases them is called hydrolysis.
Double X Extra: The specific reaction that hooks one monomer to another in a covalent bond is called dehydration synthesis because in making the bond–synthesizing the larger molecule–a molecule of water is removed (dehydration). The reverse is hydrolysis (hydro = water; lysis = breaking), which breaks the covalent bond by the addition of a molecule of water.
Although plants make their own glucose and animals acquire it by eating the plants, animals can also package away the glucose they eat for later use. Animals, including humans, store glucose in a polysaccharide called glycogen, which is more branched than starch. In us, we build this energy reserve primarily in the liver and access it when our glucose levels drop.
Whether starch or glycogen, the glucose molecules that are stored are bonded together so that all of the molecules are oriented the same way. If you view the sixth carbon of the glucose to be a “carbon flag,” you’ll see in the figure that all of the glucose molecules in starch are oriented with their carbon flags on the upper left.
The orientation of monomers of glucose in polysaccharides can make a big difference in the use of the polymer. The glucoses in the molecule on the top are all oriented “up” and form starch. The glucoses in the molecule on the bottom alternate orientation to form cellulose, which is quite different in its function from starch.
Storing up sugars for fuel and using them as fuel isn’t the end of the uses of sugar. In fact, sugars serve as structural molecules in a huge variety of organisms, including fungi, bacteria, plants, and insects.
The primary structural role of a sugar is as a component of the cell wall, giving the organism support against gravity. In plants, the familiar old glucose molecule serves as one building block of the plant cell wall, but with a catch: The molecules are oriented in an alternating up-down fashion. The resulting structural sugar is called cellulose.
That simple difference in orientation means the difference between a polysaccharide as fuel for us and a polysaccharide as structure. Insects take it step further with the polysaccharide that makes up their exoskeleton, or outer shell. Once again, the building block is glucose, arranged as it is in cellulose, in an alternating conformation. But in insects, each glucose has a little extra added on, a chemical group called an N-acetyl group. This addition of a single functional group alters the use of cellulose and turns it into a structural molecule that gives bugs that special crunchy sound when you accidentally…ahem…step on them.
These variations on the simple theme of a basic carbon-ring-as-building-block occur again and again in biological systems. In addition to serving roles in structure and as fuel, sugars also play a role in function. The attachment of subtly different sugar molecules to a protein or a lipid is one way cells communicate chemically with one another in refined, regulated interactions. It’s as though the cells talk with each other using a specialized, sugar-based vocabulary. Typically, cells display these sugary messages to the outside world, making them available to other cells that can recognize the molecular language.
Lipids: The Fatty Trifecta
Starch makes for good, accessible fuel, something that we immediately attack chemically and break up for quick energy. But fats are energy that we are supposed to bank away for a good long time and break out in times of deprivation. Like sugars, fats serve several purposes, including as a dense source of energy and as a universal structural component of cell membranes everywhere.
Fats: the Good, the Bad, the Neutral
Turn again to a nutrition label, and you’ll see a few references to fats, also known as lipids. (Fats are slightly less confusing that sugars in that they have only two names.) The label may break down fats into categories, including trans fats, saturated fats, unsaturated fats, and cholesterol. You may have learned that trans fats are “bad” and that there is good cholesterol and bad cholesterol, but what does it all mean?
Let’s start with what we mean when we say saturated fat. The question is, saturated with what? There is a specific kind of dietary fat call the triglyceride. As its name implies, it has a structural motif in which something is repeated three times. That something is a chain of carbons and hydrogens, hanging off in triplicate from a head made of glycerol, as the figure shows. Those three carbon-hydrogen chains, or fatty acids, are the “tri” in a triglyceride. Chains like this can be many carbons long.
Double X Extra: We call a fatty acid a fatty acid because it’s got a carboxylic acid attached to a fatty tail. A triglyceride consists of three of these fatty acids attached to a molecule called glycerol. Our dietary fat primarily consists of these triglycerides.
Triglycerides come in several forms. You may recall that carbon can form several different kinds of bonds, including single bonds, as with hydrogen, and double bonds, as with itself. A chain of carbon and hydrogens can have every single available carbon bond taken by a hydrogen in single covalent bond. This scenario of hydrogen saturation yields a saturated fat. The fat is saturated to its fullest with every covalent bond taken by hydrogens single bonded to the carbons.
Saturated fats have predictable characteristics. They lie flat easily and stick to each other, meaning that at room temperature, they form a dense solid. You will realize this if you find a little bit of fat on you to pinch. Does it feel pretty solid? That’s because animal fat is saturated fat. The fat on a steak is also solid at room temperature, and in fact, it takes a pretty high heat to loosen it up enough to become liquid. Animals are not the only organisms that produce saturated fat–avocados and coconuts also are known for their saturated fat content.
The top graphic above depicts a triglyceride with the glycerol, acid, and three hydrocarbon tails. The tails of this saturated fat, with every possible hydrogen space occupied, lie comparatively flat on one another, and this kind of fat is solid at room temperature. The fat on the bottom, however, is unsaturated, with bends or kinks wherever two carbons have double bonded, booting a couple of hydrogens and making this fat unsaturated, or lacking some hydrogens. Because of the space between the bumps, this fat is probably not solid at room temperature, but liquid.
You can probably now guess what an unsaturated fat is–one that has one or more hydrogens missing. Instead of single bonding with hydrogens at every available space, two or more carbons in an unsaturated fat chain will form a double bond with carbon, leaving no space for a hydrogen. Because some carbons in the chain share two pairs of electrons, they physically draw closer to one another than they do in a single bond. This tighter bonding result in a “kink” in the fatty acid chain.
In a fat with these kinks, the three fatty acids don’t lie as densely packed with each other as they do in a saturated fat. The kinks leave spaces between them. Thus, unsaturated fats are less dense than saturated fats and often will be liquid at room temperature. A good example of a liquid unsaturated fat at room temperature is canola oil.
A few decades ago, food scientists discovered that unsaturated fats could be resaturated or hydrogenated to behave more like saturated fats and have a longer shelf life. The process of hydrogenation–adding in hydrogens–yields trans fat. This kind of processed fat is now frowned upon and is being removed from many foods because of its associations with adverse health effects. If you check a food label and it lists among the ingredients “partially hydrogenated” oils, that can mean that the food contains trans fat.
Double X Extra: A triglyceride can have up to three different fatty acids attached to it. Canola oil, for example, consists primarily of oleic acid, linoleic acid, and linolenic acid, all of which are unsaturated fatty acids with 18 carbons in their chains.
Why do we take in fat anyway? Fat is a necessary nutrient for everything from our nervous systems to our circulatory health. It also, under appropriate conditions, is an excellent way to store up densely packaged energy for the times when stores are running low. We really can’t live very well without it.
Phospholipids: An Abundant Fat
You may have heard that oil and water don’t mix, and indeed, it is something you can observe for yourself. Drop a pat of butter–pure saturated fat–into a bowl of water and watch it just sit there. Even if you try mixing it with a spoon, it will just sit there. Now, drop a spoon of salt into the water and stir it a bit. The salt seems to vanish. You’ve just illustrated the difference between a water-fearing (hydrophobic) and a water-loving (hydrophilic) substance.
Generally speaking, compounds that have an unequal sharing of electrons (like ions or anything with a covalent bond between oxygen and hydrogen or nitrogen and hydrogen) will be hydrophilic. The reason is that a charge or an unequal electron sharing gives the molecule polarity that allows it to interact with water through hydrogen bonds. A fat, however, consists largely of hydrogen and carbon in those long chains. Carbon and hydrogen have roughly equivalent electronegativities, and their electron-sharing relationship is relatively nonpolar. Fat, lacking in polarity, doesn’t interact with water. As the butter demonstrated, it just sits there.
There is one exception to that little maxim about fat and water, and that exception is the phospholipid. This lipid has a special structure that makes it just right for the job it does: forming the membranes of cells. A phospholipid consists of a polar phosphate head–P and O don’t share equally–and a couple of nonpolar hydrocarbon tails, as the figure shows. If you look at the figure, you’ll see that one of the two tails has a little kick in it, thanks to a double bond between the two carbons there.
Phospholipids form a double layer and are the major structural components of cell membranes. Their bend, or kick, in one of the hydrocarbon tails helps ensure fluidity of the cell membrane. The molecules are bipolar, with hydrophilic heads for interacting with the internal and external watery environments of the cell and hydrophobic tails that help cell membranes behave as general security guards.
The kick and the bipolar (hydrophobic and hydrophilic) nature of the phospholipid make it the perfect molecule for building a cell membrane. A cell needs a watery outside to survive. It also needs a watery inside to survive. Thus, it must face the inside and outside worlds with something that interacts well with water. But it also must protect itself against unwanted intruders, providing a barrier that keeps unwanted things out and keeps necessary molecules in.
Phospholipids achieve it all. They assemble into a double layer around a cell but orient to allow interaction with the watery external and internal environments. On the layer facing the inside of the cell, the phospholipids orient their polar, hydrophilic heads to the watery inner environment and their tails away from it. On the layer to the outside of the cell, they do the same.
As the figure shows, the result is a double layer of phospholipids with each layer facing a polar, hydrophilic head to the watery environments. The tails of each layer face one another. They form a hydrophobic, fatty moat around a cell that serves as a general gatekeeper, much in the way that your skin does for you. Charged particles cannot simply slip across this fatty moat because they can’t interact with it. And to keep the fat fluid, one tail of each phospholipid has that little kick, giving the cell membrane a fluid, liquidy flow and keeping it from being solid and unforgiving at temperatures in which cells thrive.
Steroids: Here to Pump You Up?
Our final molecule in the lipid fatty trifecta is cholesterol. As you may have heard, there are a few different kinds of cholesterol, some of which we consider to be “good” and some of which is “bad.” The good cholesterol, high-density lipoprotein, or HDL, in part helps us out because it removes the bad cholesterol, low-density lipoprotein or LDL, from our blood. The presence of LDL is associated with inflammation of the lining of the blood vessels, which can lead to a variety of health problems.
But cholesterol has some other reasons for existing. One of its roles is in the maintenance of cell membrane fluidity. Cholesterol is inserted throughout the lipid bilayer and serves as a block to the fatty tails that might otherwise stick together and become a bit too solid.
Cholesterol’s other starring role as a lipid is as the starting molecule for a class of hormones we called steroids or steroid hormones. With a few snips here and additions there, cholesterol can be changed into the steroid hormones progesterone, testosterone, or estrogen. These molecules look quite similar, but they play very different roles in organisms. Testosterone, for example, generally masculinizes vertebrates (animals with backbones), while progesterone and estrogen play a role in regulating the ovulatory cycle.
Double X Extra: A hormone is a blood-borne signaling molecule. It can be lipid based, like testosterone, or short protein, like insulin.
As you progress through learning biology, one thing will become more and more clear: Most cells function primarily as protein factories. It may surprise you to learn that proteins, which we often talk about in terms of food intake, are the fundamental molecule of many of life’s processes. Enzymes, for example, form a single broad category of proteins, but there are millions of them, each one governing a small step in the molecular pathways that are required for living.
Levels of Structure
Amino acids are the building blocks of proteins. A few amino acids strung together is called a peptide, while many many peptides linked together form a polypeptide. When many amino acids strung together interact with each other to form a properly folded molecule, we call that molecule a protein.
For a string of amino acids to ultimately fold up into an active protein, they must first be assembled in the correct order. The code for their assembly lies in the DNA, but once that code has been read and the amino acid chain built, we call that simple, unfolded chain the primary structure of the protein.
This chain can consist of hundreds of amino acids that interact all along the sequence. Some amino acids are hydrophobic and some are hydrophilic. In this context, like interacts best with like, so the hydrophobic amino acids will interact with one another, and the hydrophilic amino acids will interact together. As these contacts occur along the string of molecules, different conformations will arise in different parts of the chain. We call these different conformations along the amino acid chain the protein’s secondary structure.
Once those interactions have occurred, the protein can fold into its final, or tertiary structure and be ready to serve as an active participant in cellular processes. To achieve the tertiary structure, the amino acid chain’s secondary interactions must usually be ongoing, and the pH, temperature, and salt balance must be just right to facilitate the folding. This tertiary folding takes place through interactions of the secondary structures along the different parts of the amino acid chain.
The final product is a properly folded protein. If we could see it with the naked eye, it might look a lot like a wadded up string of pearls, but that “wadded up” look is misleading. Protein folding is a carefully regulated process that is determined at its core by the amino acids in the chain: their hydrophobicity and hydrophilicity and how they interact together.
In many instances, however, a complete protein consists of more than one amino acid chain, and the complete protein has two or more interacting strings of amino acids. A good example is hemoglobin in red blood cells. Its job is to grab oxygen and deliver it to the body’s tissues. A complete hemoglobin protein consists of four separate amino acid chains all properly folded into their tertiary structures and interacting as a single unit. In cases like this involving two or more interacting amino acid chains, we say that the final protein has a quaternary structure. Some proteins can consist of as many as a dozen interacting chains, behaving as a single protein unit.
A Plethora of Purposes
What does a protein do? Let us count the ways. Really, that’s almost impossible because proteins do just about everything. Some of them tag things. Some of them destroy things. Some of them protect. Some mark cells as “self.” Some serve as structural materials, while others are highways or motors. They aid in communication, they operate as signaling molecules, they transfer molecules and cut them up, they interact with each other in complex, interrelated pathways to build things up and break things down. They regulate genes and package DNA, and they regulate and package each other.
As described above, proteins are the final folded arrangement of a string of amino acids. One way we obtain these building blocks for the millions of proteins our bodies make is through our diet. You may hear about foods that are high in protein or people eating high-protein diets to build muscle. When we take in those proteins, we can break them apart and use the amino acids that make them up to build proteins of our own.
How does a cell know which proteins to make? It has a code for building them, one that is especially guarded in a cellular vault in our cells called the nucleus. This code is deoxyribonucleic acid, or DNA. The cell makes a copy of this code and send it out to specialized structures that read it and build proteins based on what they read. As with any code, a typo–a mutation–can result in a message that doesn’t make as much sense. When the code gets changed, sometimes, the protein that the cell builds using that code will be changed, too.
Biohazard!The names associated with nucleic acids can be confusing because they all start with nucle-. It may seem obvious or easy now, but a brain freeze on a test could mix you up. You need to fix in your mind that the shorter term (10 letters, four syllables), nucleotide, refers to the smaller molecule, the three-part building block. The longer term (12 characters, including the space, and five syllables), nucleic acid, which is inherent in the names DNA and RNA, designates the big, long molecule.
DNA vs. RNA: A Matter of Structure
DNA and its nucleic acid cousin, ribonucleic acid, or RNA, are both made of the same kinds of building blocks. These building blocks are called nucleotides. Each nucleotide consists of three parts: a sugar (ribose for RNA and deoxyribose for DNA), a phosphate, and a nitrogenous base. In DNA, every nucleotide has identical sugars and phosphates, and in RNA, the sugar and phosphate are also the same for every nucleotide.
So what’s different? The nitrogenous bases. DNA has a set of four to use as its coding alphabet. These are the purines, adenine and guanine, and the pyrimidines, thymine and cytosine. The nucleotides are abbreviated by their initial letters as A, G, T, and C. From variations in the arrangement and number of these four molecules, all of the diversity of life arises. Just four different types of the nucleotide building blocks, and we have you, bacteria, wombats, and blue whales.
RNA is also basic at its core, consisting of only four different nucleotides. In fact, it uses three of the same nitrogenous bases as DNA–A, G, and C–but it substitutes a base called uracil (U) where DNA uses thymine. Uracil is a pyrimidine.
DNA vs. RNA: Function Wars
An interesting thing about the nitrogenous bases of the nucleotides is that they pair with each other, using hydrogen bonds, in a predictable way. An adenine will almost always bond with a thymine in DNA or a uracil in RNA, and cytosine and guanine will almost always bond with each other. This pairing capacity allows the cell to use a sequence of DNA and build either a new DNA sequence, using the old one as a template, or build an RNA sequence to make a copy of the DNA.
These two different uses of A-T/U and C-G base pairing serve two different purposes. DNA is copied into DNA usually when a cell is preparing to divide and needs two complete sets of DNA for the new cells. DNA is copied into RNA when the cell needs to send the code out of the vault so proteins can be built. The DNA stays safely where it belongs.
RNA is really a nucleic acid jack-of-all-trades. It not only serves as the copy of the DNA but also is the main component of the two types of cellular workers that read that copy and build proteins from it. At one point in this process, the three types of RNA come together in protein assembly to make sure the job is done right.
Meghan Groome, PhD, Director of K12 Education and Science & the City, New York Academy of Sciences
[Ed. note: Double X Science has started a new series: Double Xpression: Profiles of Women into Science. The focus of these profiles is how women in science express themselves in ways that aren’t necessarily scientific, how their ways of expression inform their scientific activities and vice-versa, and the reactions they encounter.]
DXS: First, can you give me a quick overview of what your scientific background is and your current connection to science?
MG: I was a bio major since age two. Growing up (and still today) I had a deep love of all things gross, icky, creepy, and crawly and a deep dislike of anything math related. My parents didn’t really know what to do with me, so a theme to my scientific background is that although I was a straight-A student in my bio classes, no one had any idea that I should be doing enrichment programs or making an effort to learn math. I figured that by being a great bio major, I would become a great scientist. So I was an excellent consumer of scientific knowledge but only realized late in life that I needed to be a producer to actually become a scientist.
Being a straight-A student doesn’t actually get you a job when you graduate from a small liberal arts college with a degree in biology and theater, and out of desperation, I took a job teaching. While I wasn’t a good scientist, I turned out to be an excellent teacher and loved the creativity, energy, and never-ending questions that go along with being a science teacher. If you teach from the perspective that science is an endless quest for knowledge, you’ll never get bored taking kids on that journey.
While my background is in biology, my graduate degree is in science education, and I study gender dynamics and student questioning the middle-school classrooms. I currently work for the New York Academy of Sciences as the Director of K12 Education and public programs and spend most of my day convincing scientists that education outreach is not only part of their jobs but a lot of fun.
DXS: What ways do you express yourself creatively that may not have a single thing to do with science?
MG: I’m also a photographer and spend a lot of time wandering around neighborhoods in Brooklyn with a special love of decaying buildings and empty lots. I love how nature conquers things that we humans consider to be permanent – like how we have to constantly beat back the invading hordes of plants and animals even in one of the most man-made environments in the world.
I was also a theater major, so (I) have a strong background in costume design and stage directing. I hate acting but love dance. If I had any talent I would have become a musical theater star but unfortunately enthusiasm and determination can only get you so far.
DXS: Do you find that your scientific background informs your creativity, even though what you do may not specifically be scientific?
MG: I find great joy in seeing how nature conquers human engineering. When I learned about Lynn Margulis’ Gaia hypothesis, I began seeing it everywhere and I think I love photography because I’m documenting the Earth fighting back.
Most of my creative energy comes from working with kids and listening to the wonderful way in which they think about the natural world. Adults can be so rigid in their thinking and are often afraid to say ideas that are out of the mainstream thinking. The older a kid gets, the more we expect them to conform to the adult way of thinking. Middle-school kids are old enough to express their wacky ideas, and young enough to not recognize that their ideas are considered “wrong.”
DXS: Have you encountered situations in which your expression of yourself outside the bounds of science has led to people viewing you differently–either more positively or more negatively?
MG: People tell me all the time “You’re not what we expected” and I’m not really sure how to respond.
In the science education world, my research is informed by my experiences teaching in a very poor district and from a social justice perspective. It’s a rather controversial theoretical framework because it says, “I have an agenda to use my research to bring about equity in an unequal world.” From a research perspective, it means you need to be explicit in your point of view and your biases and have much greater validity and reliability to show that your research is solid. My work is very passion driven so I’ve had to learn when it’s appropriate to pull out my soap box and go full-out social justice to them.
This is changing, but for a long time I kept my personality under wraps in a professional setting. It’s only now — with 10 years professional experience, great organizations on my resume, and a PhD — that I can be clever, confront those I disagree with, and even smile. Anyone who’s ever had a beer with me knows that I’m a goofball and will do just about anything to make someone laugh. I’m a science person, a theater person, a teacher, researcher, policy maker, consultant, and have seen a lot of exquisitely bad and good stuff in my life and so I am frequently the voice of an outsider even though I look and sound like a total insider. That can really freak people out especially if they’ve only read my bio or seen me in my most professional mode.
DXS: Have you found that your non-science expression of creativity/activity/etc. has in any way informed your understanding of science or how you may talk about it or present it to others?
MG: I approach teaching science from a fairly theatrical perspective. In my class we dance, sing, laugh, talk about the real world. I’ve never used the textbook, and I’m very insistent that everything be in the first person when writing or speaking about science. I much prefer teaching regular classes — not honors or AP — and can’t stand kids who remind me of myself in high school.
I approach scientists in the same way and try to make them comfortable admitting that their more than a brain on a stick. I’ve found one of the biggest fears of young scientists is that their PI will find out that they’re interested in something more than life in the lab so I always try to work within the existing power structure and make sure the PIs and Deans indicate to them that working with the (New York) Academy (of Sciences) is okay.
DXS: How comfortable are you expressing your femininity and in what ways? How does this expression influence people’s perception of you in, say, a scientifically oriented context?
MG: This question confounds the heck out of me. I am still such a tomboy and have always chosen to present myself as a somewhat genderless individual. I’ve always considered myself “smart not pretty” because I can control how smart I am but not how pretty. A few years ago, my sisters pulled me aside and told me I needed to stop dressing like such a slob. They started buying me pretty, fashionable clothes and insisting that I wear skirts above the knee and get a real hair cut.
Since I started working at the Academy, I have a very public facing role and have grown to accept that I should look nice. This goes along with slowly feeling comfortable letting my personality out in professional settings but I still consider myself a tomboy and consider my outward appearance to be a costume designed to do a job.
So I guess the answer is, femininity, what femininity?
DXS: Do you think that the combination of your non-science creativity and scientific-related activity shifts people’s perspectives or ideas about what a scientist or science communicator is? If you’re aware of such an influence, in what way, if any, do you use it to (for example) reach a different corner of your audience or present science in a different sort of way?
MG: I think very few people are brains on a stick but that being a scientist often requires us to pretend we have no life outside the lab. I’ve now worked with hundreds of young scientists who spend time working with kids and I’m so pleased to see how quickly they shift from lab geek to real person when talking with a 4th grader. I want scientists to be evangelicals for science, and I want that to include the fact that scientists are real, fallible, wacky, wonderful people too.
DXS: If you had something you could say to the younger you about the role of expression and creativity in your chosen career path, what would you say?
MG: I was always encouraged to be an individual and be myself. I credit my parents with allowing me to pursue my passion and not try to box me in to one identity. It’s never been easy to forge my own path, and I dedicate a lot of myself to my work.
My advice to my younger self would be to slow down a bit, know that you don’t have to get 100% on everything, and know that the problems of the world don’t have to be solved right now.
And perhaps to learn how to be a bit more like a girl. It’s incredibly powerful to see yourself as smart and pretty.
——————————————————————— Meghan Groome is the Director of K12 Education and Science & the City at the New York Academy of Sciences, an organization with the mission to advance scientific research and knowledge, support scientific literacy, and promote the resolution of society’s global challenges through science-based solutions. After graduating from Colorado College in Biology and Theatre, she desperately needed a job and took one as a substitute teacher at a middle school in Ridgewood, NJ. She discovered that she had a knack for making science interesting and enjoyable, mostly through bringing in gross things, lighting things on fire (but always in a safe manner), and having a large library of the world’s best science writing and science fiction. After teaching in both Ridgewood and Paterson, NJ, she completed her PhD at Teachers College (TC) Columbia University with a focus on student question-asking in the classroom. While at TC, she was a founding member of an international education consulting firm and worked on projects from Kenya to Jordan with a focus on designing new schools and school systems in the developing world.
After graduating, Dr. Groome became a Senior Policy Analyst at the National Governors Association on Governor Janet Napolitano’s Innovation America Initiative. Prior to her work at the Academy, Dr. Groome worked at the American Museum of Natural History and authored the policy roadmap for the Empire State STEM Education Network and taught urban biodiversity in the Education Department. At the Academy, she is responsible for the Afterschool STEM Mentoring program, which places graduate students and postdocs in the City’s afterschool programs, and the Science Teacher program, where she designs field trips and content talks to the City’s STEM teachers.

Jennifer Canale is a Senior Microbiologist for the United States Food and Drug Administration (FDA) in Queens, NY, as well as an adjunct microbiology lecturer for City University of NY (York College and College of Staten Island). Jennifer is also passionate about promoting women in science and leads an annual women in science event at the FDA as a means to promote awareness about gender discrimination in the workplace. [DXS] First, can you give me a quick overview of what your scientific background is and your current connection to science?
[JC] I have always been interested in science, and since most of my family worked in Bellvue Hospital, I was very comfortable around people in lab coats. In the early seventies, at the age of 5, I announced to my grandfather, the X-ray technician, and his brothers (my great uncles) that I wanted to become a doctor, specifically a doctor that delivers babies.
My grandfather was proud and my uncles were dismayed. My uncle Joe said to me, “Jennifer, you mean a nurse like your cousin Joanie, right?” My cousin Joan applied to Medical School in the sixties and the same group of uncles convinced her that her fiancé, Warren, wouldn’t wait 4 years to get married and it was more lady-like to be a nurse. Today she is a retired left-handed OR nurse that specializes in cracking open chests for cardiac surgery, not so lady-like after all. So in an attempt to not have a repeat of Joanie, my grandfather jumped to my defense against his brothers and said that ‘she can be a doctor if she wanted to be’, and, furthermore, his niece Joanie was smarter and more capable than most of the doctors he worked with and shouldn’t have had to take orders from them.
My uncles agreed that there was no question of the intellectual prowess possessed by both Joanie and myself, and their reluctance came out of concern for me. They worked in the hospital, too, and saw how male doctors would abuse the female ones and make their lives more difficult because they didn’t want to allow girls in the all-boys club. “Do you want our baby – our most precious blood – to have to fight her whole life for this? What about the family – how will she find a husband and bring us more children if she sticks her nose in a book the rest of her life?” These arguments sounded a lot better when they were stated in Sicilian. Back then, the concept of ‘women can have it all’ – work and family – was not the norm like it is today.
My grandfather came back with his final answers to them. I was his granddaughter, I looked just like him, I was a fighter just like him, and this is America and she will be what she wants to be, ‘End of Story’. My uncles agreed that I was his granddaughter, I looked just like him, and I was a stubborn mule just like him, so he was probably right and they would pray for me and secretly hope I would change my mind.
Now this all transpired in front of me in a combination of English and Sicilian while I stood there in my denim overalls with a Tweety Bird patch. I was listening, and since I was only beginning to learn Sicilian, I only caught a couple of words: blood, children, book, change, and I misunderstood the word for fighter as “afraid.” I added to my grandfather’s “end of story” remark that I was not afraid of blood, I can learn how to deliver children from a book, and questioned why they wanted me to change- those overalls were my favorite!
My family was supportive to a point, but when I asked for an erector set for Christmas, I got a Barbie town house. When I wanted to go camping with the Girl Scouts, I was sent to dance school (but, much to my amazement, I enjoyed that until I was 17). My parents started giving in around 3rdgrade, and I got the panda bear-shaped calculator I wanted, as well as the robot toy 2XL featuring the 8-track tape. My mom would beg me to watch Little House On the Prairie, but I preferred Star Trek (the original Kirk version), Lost in Space (Danger Will Robinson), and Land of the Lost. Of course this was all my dad’s fault according to mom – he was the sci-fi guy, but he always said, “Jen was born this way!”
My parents eventually gave up, and my uncles kept praying for that change of mind, but I spent the late seventies and early eighties winning science fairs with experiments my Uncle Ben, the electrician, rigged for me. They thought there was hope for me to be more “lady-like” in 1984 when I started high school and wanted to try out for the cheerleading squad, but the teachers advised me that “the cheer squad” was no place for an “honor student” like me. So it was off to advanced placement Biology and Chemistry, and by graduation in 1988, I was accepted to the pre-med program at NYU.
I graduated from NYU with honors, and my parents got me two presents: my name in diamonds and a stethoscope. My grandfather bought me a set of crisp white lab coats and gloated to his brothers with a cigar in his mouth. Apparently a bet was made amongst them and from hence forward they had to call me “doctoressa,” the hybrid feminized version of doctor in Italian.
The NYU pre-med was highly competitive – a constant process of elimination from 500 students (1:3, female:male) down to only 109 of us actually completing the program. The men thought it was strategic to flirt with the girls and convince us that we shouldn’t become doctors but instead should marry them. The guy that told me that got a punch in the stomach – in the name of the other women that worked. It was also apparent that many were planting the seeds of doubt in the pre-med females, stating that if we became doctors, then we wouldn’t be able to have a family. In essence, we were being told that we would be giving up the chance to have children. You had to go against your “true female nature” to breed and nurture and (instead) become a selfish and testosterone-like human to make it in this field. That was the nail in the coffin for a lot of the women in my program. The most brutal tactic and final blow to confidence was when I heard someone say that “only the ugly girls become doctors because no man would want them.”
In the nineties – halfway through college – I did change my mind, and my uncles were dancing in the streets. They thought I met a nice boy in college and I was going to settle down, give them more kids, and make sauce and meatballs on a Sunday like the good Paesana I was supposed to be. I announced I didn’t want to be an MD anymore, I wanted to be a PhD, instead. I wanted to be a SCIENTIST, do research, and maybe teach in a university. A “Scientista”-“Professoressa” “Aiuta Dio” (which means help us god)! Back to church and the rosary beads. When I got my master’s degree in microbiology, the family was just convinced I liked to collect graduation hats.
There was a feeling among my family members that science was a “boy thing,” and my cousins teased me as a result. They considered me a nerd and less feminine than my other girl cousins. I was told that I would never get married and have kids because I am a bookworm. Even in the mid-’90s, I had friends that told me not to tell guys that I was a scientist because they wouldn’t ask me out. I was kind of cute and only told a guy the truth about my profession if we got serious. As an experiment, I told one guy I met that I was a scientist and he said I looked too sexy to be that smart – and then he walked away.
I met discrimination on both sides of the stereotypical coin, in academia and in the work force. I was told when I was interviewing for graduate schools (and then for science jobs) that I had several strikes against me. First, strike one, my thick Staten Island/ Brooklyn accent supposedly made me sound less intelligent. My mentor in graduate school, Dr. Mark Albano, said to tell people to kiss your “you know what” because as long as I could discuss topics like “molecular genetics” who cares how it sounds. Besides he found my accent endearing, especially because it made boring topics sound more interesting.
Strike two was my long hair. I was told that my long hair was not practical in a scientific environment, and if I looked too glamorous on interviews I would not be taken seriously. I put my hair in a bun and toned down my make-up, but I didn’t cut it. Apparently, I looked too feminine, especially given my major curves, and even my power suits could not hide that. Women at the time were dressing very masculine (think early Miranda on Sex in the City) to compete with men for jobs. When I got the interview for my first job with Dr. Moretti in the Reproductive Immunology Lab at St. Vincent’s Medical Center in Staten Island, I remember wearing a black and white houndstooth print sheath dress with a matching short suit jacket, accessorized with pearls. Dr. Moretti said I was like Rosalind Franklin and Jackie Kennedy all rolled up into one, with a side order of cannoli.
The early 2000s arrived, and attitudes toward science changed. Shows like CSI became wildly popular. Science fiction movies about transforming robots became blockbusters. People began to use technology in their everyday lives, such as smart phones, tablets, and car navigation systems, and it suddenly became “cool.” I met my husband in 1999, and since I really was into him, I told him the truth about being a “microbiologist” from the start. He said, and I quote, “Wow, your smart, sexy, and Sicilian – it’s like I hit the Lotto!”
My wedding was the most joyful event in our family’s history because most of them thought that would never happen. I still get teased by my family when I give a long, drawn out scientific explanation of something or when I bake and make exact measurements of ingredients with my Pyrex bakeware with both the ounces and metric conversions. My husband responds for me and says “he learns something new everyday and hopes that our son becomes a nerd just like his mommy.”
So now I have it all: I am a female scientist, a wife, and a mother, even though others didn’t think that would be possible. But I always knew it would happen. I understood and forgave my uncles because I knew that they wanted to protect me, not hinder me. As for all my doubters I regularly take Dr. Albano’s advise and tell them to kiss my “you know what!”
Even my current supervisor, Maureen Coakley, recently told me in an interview that I am an “anomaly,” meaning that I am a flamboyant scientist. That was one of the best compliments I ever received. I am who I am, and that is why my playlist on my iPhone has the “Big Bang Theory Theme Song” followed by “I’m sexy and I know it!”
Times have changed. Perceptions have altered in a good way, but not entirely. Lesson learned from both academia and the school of life is that some people will get you and some people won’t. If they don’t, don’t take it personally because it is their loss and their ignorance. Some people see the person, and some see the stereotype. All you can do is try to educate them in an attempt to bust the stereotype. The only perception that matters is how you perceive yourself and use that perception as a means to become the woman that you were meant to be.
[DXS] What ways do you express yourself creatively that may not have a single thing to do with science?
[JC]Ever since planning my wedding in 2004, I have been interested in event planning. I have a knack at coordinating events, which I do as part of my collateral duties at FDA, where I have served as the Women’s Program Coordinator for the past 9 years. People call me the ”Fun Fairy” because I can be very creative and take any topic, put a different and interesting spin on it, and present it to a group in very entertaining ways. My creativity is driven by my intellectualism, and I incorporate that into something fun and memorable. I always make little inexpensive favors – buy them to give out to my audience – that are”theme oriented,” and they keep them as a reminder of the event.
The people I work with have whole collections of these favors, and they remember what each one stands for. For instance, the Women’s History Month theme for one year was “Our History is Our Strength.” Before planning this event, I had attended at NYU the Satellite Summit of National Women’s Conference hosted by Maria Shriver (then 1st Lady of California) and the First Lady, Michelle Obama. So I thought I would highlight the contributions of the First Ladies to US history. I found an educational video on the history of the First Ladies, did a presentation on the Satellite Summit, and even had a fashion show featuring of reproductions of Jacqueline Kennedy jewelry collection (my favorite first lady). I used the symbol of a “Cameo” to represent the first ladies, and so I made a huge paper one with beads on tulle on my bulletin board with pictures of the first ladies around it and gave out cameo bracelets that I made from gluing plastic cameo buttons on ribbon. Everyone still has a cameo on their desk at work, occasionally conjuring up memories of my First Ladies event.
[DXS] Do you find that your scientific background informs your creativity, even though what you do may not specifically be scientific?
[JC]My entire life is influenced by, or even revolves around, “Science.” I love science fiction movies, books, comic books, etc. Any inspiration I get for any of my creative projects always has some root in something “science-related.” I also think that my background in science helps make my visions come to life. Even the smallest details like the stemware I chose for my wedding was a Mikasa pattern that resembled a DNA double helix, or a hexagonal candleholder that looked like a benzene ring (at least it did to me!). Another example comes from my Women’s Program, when the theme was “Writing Women Back Into History.” So I found a book called The Women of Apollo, which gave the untold story of the women engineers who had critical contributions to the Apollo Space programs. For me, all roads lead back to science.
[DXS] Have you encountered situations in which your expression of yourself outside the bounds of science has led to people viewing you differently–either more positively or more negatively?
[JC]I have experienced both negative and positive views by others when I am expressing my self creatively. On one hand, there were people that associate planning events with a negative stereotype of being a “party-girl” or “bimbo” type that cares more about the “girly fun” stuff than the serious business of science. On the other hand, there have been people who constantly praise me for presenting science-related topics in entertaining ways. The latter view me as a “flamboyant scientist” who shares her knowledge in an interesting manner. In this life you will never please everyone; only seek to please yourself and your loved ones because those are the only opinions that matter.
[DXS] Have you found that your non-science expression of creativity/activity/etc. has in any way informed your understanding of science or how you may talk about it or present it to others?
[JC]In planning these events, I have come up with a formula of sorts to create a successful soirée. Of course, this formula is an entire science in itself. I have to consider things like timing, lighting, printed materials (programs, table cards, menus, etc.) and a gamut of other things that involve an understanding of science. I am a biologist with a minor in chemistry, but the more I do these events, the more I get into things like astronomy (for a celestial-themed wedding, for instance). I mention lighting, which seems so simple, because it is actually quite complicated – getting the right reflections and materials to use (i.e.- LEDs, wax candles vs. battery operated, the limitations of pyrotechnics in party venues) is critical. Even in doing crafts for favors and printed materials, like event programs, I’ve learned different scientific techniques, such the right kind of bonding agent to use to attach ribbons, charms, or vinyl decorations, or even the use of edible ink in printers to make fondant or wafer decorations to put on cupcakes or cakes. It is a continuous learning experience.
[DXS] How comfortable are you expressing your femininity and in what ways? How does this expression influence people’s perception of you in, say, a scientifically oriented context?
[JC]I am comfortable with expressing my femininity in the way I dress and conduct myself in any setting. Although, many years ago, I was advised to dress in suits and tailored shirts similar to a man and wear neutral make-up or none at all if I wanted to be taken seriously in the scientific world, I went against the grain. I am a curvy girl, and there is no hiding my femininity. So I embrace it. I wore suits, but nothing drab – always something like a red or purple skirt suit with heels. I adhere to work environment rules like no open toe shoes in the lab, which is a safety concern, but I do not downplay my female attributes to fit in, or to present a more palatable image to my scientific peers. I do not concern myself with people’s perceptions of me based on my looks because once I “speak” and “communicate” scientific concepts, there is no question of my prowess. I am what I am, and that is a female scientist, and I pride myself in being a “stereotype buster.”
[DXS] Do you think that the combination of your non-science creativity and scientific-related activity shifts people’s perspectives or ideas about what a scientist or science communicator is? If you’re aware of such an influence, in what way, if any, do you use it to (for example) reach a different corner of your audience or present science in a different sort of way?
[JC]I think that being the “flamboyant scientist” works in my favor, and as a science communicator, it is effective all aspects of my life. As an adjunct professor, my students often thank me for making science fun and understandable. As a scientist, my colleagues and interns find my training methods to be memorable and actually increase their understanding of the job. As the Women’s Program Coordinator at the FDA, I create unforgettable events that people look forward to and learn a lot from. As a wife, mother, daughter, aunt, cousin, and friend, I am the “Fun Fairy” (pictured with wings and a lab coat), and their lovable nerdy girl.
I feel my true gift is being able to communicate science. My mentor in graduate school always told me I had the talent of taking complicated scientific ideas and expressing them in a way that anyone could understand. I have some ideas brewing involving science books for children and teens, and I would like to explore these avenues in order to share this gift with others. I would also like to get involved in maybe writing for popular science publications, if given the opportunity.
[DXS] If you had something you could say to the younger you about the role of expression and creativity in your chosen career path, what would you say?
[JC]I would say be true to yourself. Whatever path you take career-wise, always remember that is could be something you will be doing the rest of your life. Yes, there are financial considerations to make, but if you do not have that creative outlet incorporated into your career, then you will be miserable. I am the happiest at work when I am planning a Women’s Program alongside doing experiments or going to my second job as a professor at York College. You need the creativity to keep the blood flowing. Where would science be without creativity? Find what your talent is and what makes you happy, and then apply it to your career. That is the secret to success.
Darlene Cavalier (Twitter) is the hard-working and seemingly tireless founder of Science Cheerleaderand SciStarter. She has held executive positions at Walt Disney Publishing and worked at Discover Magazine for more than 10 years. Darlene incorporated her experience and knowledge in serving as the prinicple investigator of a $1.5 million grant from the National Science Foundation to promote basic research through partnerships with Disney and ABC TV and also has collaborated with the NSF, NBC Sports, and the NFL to produce the Science of NFL Football series. She holds a master’s degree from the University of Pennsylvania where she studied the role of the citizen in science and is herself a former Philadelphia 76ers cheerleader. In addition, she is a writer and senior adviser to Discover Magazine. You can find her full biography here.
On top of all of that, she is also mother to four children. You might be able to blame them for the two-day stomach flu Darlene was just getting over when she talked with Double X Science Managing Editor Emily Willingham about why women pursue professional cheerleading (hint: it’s much more about passion than pay), why cheerleader stereotypes are “bunk,” and why even if Science Cheerleader doesn’t lead all little girls into science, it leaves them with a message about being secure in who they are.
DXS: First, can you give me a quick overview of what your scientific background is and your current connection to science?
A: So I have no formal science degree. My connection to science is that I work and continue to work at Discover magazine. I worked there as business development coordinator, and that’s how I became reintroduced to science. I became a fan of science later in life. After working at Discover for a couple of years and having some children [Cavalier is the mother of four children], I wondered if there was a more significant role for someone like me without a formal science degree. My role at Discover had become curating science on behalf of the magazine. How do we get average public to move in the direction of science literacy?
I went to grad school at the University of Pennsylvania to look at those issues. When I met with an advisor (there), he recommended that I go for a masters in liberal arts, which made sense to me at the time. They created a curriculum for me. Most was in the history and sociology of science and some was in school of education. Piecing all of this together was a turning point for me in my life both prof and personally, I started to learn about these citizen scientists to engage nonscientific members of the public in real scientific research.
I saw huge gaps in getting people to move in that direction. Other countries were enabling citizens to take part in conversations about science policy on national levels. The U.S. didn’t have mechanism for that. That was one gap I saw. Another was people weren’t getting involved in citizen science projects…(they were) hard to find and scattered all over websites. It was a mechanism problem, not philosophical or societal. In grad school, I created a matchmaking site of all citizen science projects I was coming across. I decided to make that database public for people to add their projects, and made it searchable. There were no cheerleaders involved in science cheerleaders when I started the blog…it was about the citizen science projects and reopening this agency for public input. (It was not about) cheerleaders specifically.
DXS: So how did you end up incorporating the cheerleader aspect?
A: That was basically a fun way of using my background–it is surprising to people that I was a (Philadelphia) 76ers cheerleader. I kept it secret for long time at Discover, fearing I wouldn’t be taken seriously. I wish I hadn’t attempted (to keep it) secret; when it was “exposed” at Discover people were great about it. They thought it was pretty neat. So I became more comfortable in that role. I wanted to do a tongue-in-cheek look at this when I was starting the blog that this site really is for everyone. Citizen science projects are for everyone; it doesn’t matter if even a quote–unquote “ditzy blonde cheerleader” can do it, surely the scientists could figure it out, and the politicians.
(When the concept of Science Cheerleader really took off), we thought, “We’re on to something.” Most people loved it. Criticism came from feminist science bloggers, which I totally understand…I learned something there, too… (this idea of), “these women aren’t scientists, what are they doing?” Then I started getting emails from actual NFL NBA cheerleaders, (telling me) “I’m getting PhD in chemistry,” (and saw it as) a great way to merge two parts of my life. I could hardly believe it. I never even had thought to ask cheerleaders if they were studying any of the STEM fields.
It became cyclical. The founder of the U.S. Science and Engineering Festival called and asked Science Cheerleader to come to that festival and perform. I had to tell him I’d never met them. We got a grant from the Burroughs Wellcome fund to cover travel for 11 science cheerleaders to come to Washington and perform. They had awesome outfits, speaking roles. It was more or less an experiment. Amazing performers against a science theme routine and incredible public spokespeople. Applying their talents of being enthusiastic about their team to science and tech careers. They were a huge hit at the festival.
We left each one speak their own language. They’re very diverse. It helped to have that diverse makeup and watching them talk to little kids. Little girls would come up to them, almost like when you see Cinderella, would want their autographs, to touch their uniforms, feel their pompoms. It was a great opportunity to say, “We love cheerleading, but in the daytime I make cars, I’m what you call an engineer.” Some of the dads and the moms were more attracted to the team (the cheerleaders) represented, and they learned that no cheerleader makes a living on 35 bucks a game…they have professions.
We started to realize we were challenging stereotypes of scientists, cheerleaders, engineers. We have so many science cheerleaders in the database, working now with the NFL and NBA, (that) when a local event is happening, I can contact science cheerleaders in the Boston area tell them, and they can go if they want. They don’t have talking points … they say what they want to say. A Patriots cheerleader says cheerleading was great for her professional career, standards were super high for her in college. (You have to maintain) a GPA to be cheerleader and athlete, (and that) was helpful.
DXS: And you’ve encountered some criticism from feminists or women in science. How do you handle that?
A: You can’t be a science cheerleader unless you have science connection. I’m the only fraud in the group. That’s the criterion. What is different, there was so much media play…NPR, CNN, TODAY Show, you can only get across so much in a video. A couple of people took a video where someone says “go science” and assumed we’re just dressing people up as cheerleaders and sending them around to yell that. (But) there’s a lot of depth with what they do.
Many are very accomplished in their fields, going on to do research. One is getting her PhD in chemistry, working on gold nanoparticles to treat pancreatic cancer. That criticism that’s ill informed is the worst type. Putting them in a bad light and they don’t deserve it. They volunteer to do this. They do it because they really believe in it. There are an estimated 3 to 4 million cheerleaders in the US. They want to reach that group, let them know it’s OK to love math and science, (to say) here’s my experience, here’s how I learned what an engineer is, here’s what my day is like. They’re all available to be pen-pal partners. As much as we preach “don’t let other people bother you or criticism bother you,” I don’t like to see ill-informed or misinformed statements.
Q: Have you encountered situations in which your expression of yourself outside the bounds of science has led to people viewing you differently–either more positively or more negatively?
A: Yes. (What) we have is mostly anecdotal…have a number for people coming to site, watching video, we try to save emails and letters that come in from moms of little girls who just want to be cheerleaders but also are talented, and the moms feel they’re talented in math and science and grow concerned about their daughters losing that for their love of cheerleading and dance and are happy to see these role models on the site.
In terms of other positive impacts, if we just look at it from public outreach, it’s been incredible because of the media’s interest. Media interest in this, the teams themselves…it’s not easy to reach Baltimore Ravens fans w positive messages about science and tech or women and science and tech, so when the Ravens repost the interviews and tweet it to their fan base, that’s very positive.
Lines at live events are pretty long with kids lining up to get autographs from the Science Cheerleaders. We always look for local or regional citizen science activity to capitalize on that attention to get those people to do something. For example in South Texas a science and engineering festival. We did our routine, a bunch of people line up for autographs, our choreographer is the reigning Miss United States. That attracts people as I talk about a local researcher who needs their help for citizen science project. (It’s) super simple to use that attention to say “hey, by the way, you’re needed. When you see this crayfish–hold up a picture–it’s considered invasive. Here’s Dr. Zen!” He (Dr. Zen) came out and talked, while they’re waiting inline, a captive audience, and we give the Website where they can get involved.
Our sister site, is now a full-size website called SciStarter, a startup company. That was named one of Philly’s top-10 tech startups last year! It aggregates all of the citizen science projects out there. We rely on that at all of the Science Cheerleader appearances.
I can do what I know how to do, but I would love some grad student or organization that does evaluations or measures outcomes and help me learn more about the metrics, direct outcomes that can be measured, and how do I do that.
DXS: Have you found that your non-science expression of creativity/activity/etc. has in any way informed your understanding of science or how you may talk about it or present it to others?
A: It’s a great question. It’s interesting because that Science Cheerleader blog that I started with and still have–it’s a very diverse audience. There are people who came because they’re reading about their favorite teams’ cheerleaders doing cool things and that ‘s great. I’d have a lot of those types coming to the site, and they’d learn, “hmm that’s interesting I didn’t realize that’s what a chemical engineer does,” then look to their right and see, “hmmm this is happening in Boston”… and take next step from passive reader to getting involved in a citizen science project. The goal is to move them to being actively engaged citizens getting them prepared aware involved in the science policy conversation. I know that sounds so farfetched but not nearly as much as a couple of years ago.
It is not easy to talk to different audiences. I used to preach “know your audience,” but I’ve learned more from my audience than they may have from me. I consider some of the science bloggers, and they’re a part of the audience. I learned they don’t like 76ers involved without science degrees, and we responded to that. What one group likes another won’t. There’s no “one size fits all.” We try to (appeal) to a wide variety of audiences coming to site….from those interested in science policy to people who come because they want more about citizen science efforts. We can point them to these things through SciStarter.
DXS: How comfortable are you expressing your femininity and in what ways? How does this expression influence people’s perception of you in, say, a scientifically oriented context? And does that impression evolve at all?
The initial impression, even through me–and I think the Science Cheerleaders would say this too, even when I was of the Sixers…(pauses)… let’s talk motivation for a minute, why most of these women choose to become professional cheerleaders, why would you do that? The bottom line is that there are very few opportunities to continue dancing and performing once you’re out of college. My personal experience–and you’ll see this in interviews–your options are so limited, and we wanted to continue performing, usually it’s dancing. We see an audition in paper, and they’re looking for people who know how to do triple pirouettes, and the opportunity to continue to perform is there.
I wish we didn’t have to wear those uniforms when I was on the Sixers. I loved every single thing about it except for some of the uniforms. I would love for the NFL and NBA to look and say, “We didn’t realize cheerleaders felt that way and tone it down,” (but) it’s not going to happen. I encourage people to read interviews to see what motivated some of the cheerleaders. I wasn’t a gung-ho Sixers fan who wanted to do this for the team, but some people almost their whole lives dreamed of being a cheerleader for their team.
In terms of embracing being feminine, I don’t know anyone who is that 100% of the time. My hair looked decent, I wore OK clothes, but I don’t walk around like that all the time. I think that the reality of the situation is there’s no one walking around looking like a professional cheerleader all the time. I doubt that the Science Cheerleaders look like that when they go into the lab, not because they want to be taken seriously but for convenience. It s a lot of work to look like that.
I wish that the people who pave the way for these Science Cheerleaders to be exploring the careers they have now–lots are supportive and embrace them but that also happens to be where the toughest critics are embedded. They know better than anyone what it feels like to have somebody work against you. I wish they’d ease up on Science Cheerleaders and let them be all that they can be. They can relate to an audience it’s not easy for us to reach. I can’t reach those little cheerleaders out there myself, but they can, maybe through pom-poms or uniforms or a connection with the moms. It does evolve
Some teams require you to be in school full time or have a full-time job. They want smart cheerleaders because you have to be out doing public speaking so if you’re not articulate or bright…pretty girls and good dancers are a dime a dozen…your success comes down to your interview.
These Science Cheerleaders are by far way more secure in their dual roles than I was. I’m not sure why or how, but when you see them at appearances, they’re looking for ways to embrace these two roles. They’ll say in their interview, I don’t care what people in my lab think about my wearing makeup and so on, and they mean it. These women walk the walk.
DXS: If you had something you could say to the younger you, back when you weren’t so comfortable with yourself about the role of expression and creativity in your chosen career path, what would you say?
A: If I had read one of these interviews when I was, say, in fifth grade, and I read one of those Science Cheerleader interviews, it would resonate w me in a different way. It might not have an impact on me personally when I was a kid…the cheerleaders on our team, we were athletes. Most cheerleaders are leaders in their schools, involved in leadership and academics, student government. The stereotype is total bunk.
I can tell you that in some point in my life, I can think back to times, like my first big job at Discover, had I read these interviews as a kid, I may have felt more comfortable about being authentic about every aspect of me.
To use the Pop Warner example, we set a world record with them, 1300 little cheerleaders cheering for science for five minutes. I have a sneaking suspicion that fast forward 10 years from now, they might be interviewed, by you maybe, about how they got interested in science, and they might say, when I as in 8th grade, I got called in to do this science cheer thing, and it opened my eyes to science as a valid career. If it doesn’t happen at a young age for some of these girls, they might reflect back to something they experienced science cheerleading and feel entitled to embrace all that they are and feel good about that.
