The Biology of Zombies

Night of the Living Dead (1968)

I am that girl who is the least fun to watch movies with (or the most fun, I guess, depending on your idea of fun). I love science fiction and respect artists and writers who alter the science of our world to tell stories — but I’m still going to want to have that talk at the end that starts with, “But it wasn’t actually that realistic when…”

For about a year now I’ve been interested in doing some writing about the biology of zombies. They’re ubiquitous in modern culture and stories tend to take a half-assed shot at the science, as if they feel they need to provide a mechanism for the spread of flesh-craving, but they can’t quite figure out how to make it work.

So when Krystal D’Costa of the fabulous blog Anthropology in Practice brought up Zombie Awareness Month last week on twitter, I couldn’t help but throw some ideas out there. And when she suggested that we do some organized zombie blogging, I couldn’t resist. She has a great post up about the anthropology of zombies — check it out here!

And then when I got down to research … I had so much that I wanted to say that one post was not going to be nearly enough. So get ready for a fun-filled week of zombie science!

What I’m mostly interested is the science fiction aspect of it — not trying to make up my own theory for how zombies could actually exist (though that is obviously part of the fun of this analysis!), but rather exploring the theories of different stories. I’m going to write about several causes of zombie-ism (bacteria, chemicals and viruses) focusing on a particular work or two, plus a day for zombie neuroscience and one for zombies in nature. I’ll update this post with links as the week goes on.

I’d love to hear your thoughts, especially comparisons to other books/movies/television, since I have not come close to exhausting the possibilities.

Don’t forget to visit Anthropology in Practice to learn about the public fascination with zombies.

Zombie Biology, Pt. 2: Zombie neuroscience

This is the second post in a 5-part series on the biology of zombies. More info and links to other posts here.

Zombies in The Walking Dead

When I watched the first episode of The Walking Dead series, based on the comic book series of the same name, I was stunned: “They can show this on TV?!” Apparently we now live in a society where it’s ok to show a horse being disemboweled, with a mere warning of graphic imagery at the beginning of the episode. Some of my friends thought the plot dragged on through the first season a bit, but I loved it.

And one of the show’s most endearing details to me was that the safe haven city (supposedly) was Atlanta, Georgia. Not because I think it’s a great city or anything, but because this choice showed the emphasis the writers put on science: Atlanta was the city worth protecting because it is where the headquarters of the Center of Disease Control (CDC) are located. After all, if anyone is going to cure a zombie outbreak, you’ve gotta protect your scientists!

The zombie virus spreads into the brain in The Walking Dead

After surviving countless horrors, Rick and his small posse of survivors finally make it to the CDC, expecting to find a city of scientists working swiftly to find a cure for zombie-ism who would take them in. But when they go inside, they find a single man — the last man standing, working alone towards a cure in the vast complex.

Because no mad scientist is able to hold in his secrets, he quickly gives in and explains to them what he knows of the science behind the zombie outbreak. He asks his computer to call up TS-19: A video of the electrical impulses in the brain of Test Subject 19, a volunteer who allowed the scientists to study her as she succumbed to her zombie bite. As they watch the neuron’s of the still-human brain flicker on the screen before them, Dr. Jenner explains:

Somewhere in all that organic wiring, all those ripples of light, is you — the thing that makes you unique and human… Those are synapses, electric impulses in the brain that carry all the messages. They determine everything a person says, does, or thinks from the moment of birth to the moment of death.

The survivors gaze slack-jawed at the light show before them until the brightness begins to dim, with black roots growing up from the base of the neck into the brain, until everything goes black. “What is that?” they ask. Luckily, they have a SCIENTIST in the room!

It invades the brain like meningitis: the adrenal glands hemorrhage, the brain goes into shutdown, then the major organs — then death. Everything you ever were or ever will be, gone.

But wait, there’s more. After a little while, between 3 minutes and 8 hours, according to Dr. Jenner, the black roots turn to a glowing red, reactivating just the brain stem. (I’ll give the writers the benefit of the doubt and say the scientists recolored the zombie electricity later for effect.)

It basically gets them up and moving… [but] it’s nothing like before… Dark, lifeless, dead. The frontal lobes, the neocortex, the human part — that doesn’t come back. The you part.

While a nice shot, this explanation wasn’t satisfying enough for me. Sure, the brain stem might get em moving, but what makes a zombie want to eat other people? What makes them murderous, and angry?

I’m fortunate that I didn’t have to do this research because it would take far too many hours to get me competent in brain territory. But Dr. Steven Schlozman of Harvard Medical School made a fabulous video going through each aspect of zombie behavior and explaining what parts of the brain must be reactivated for a zombie to really exist! (via bioephemera)

But there is another zombie-related brain question — why do they want to eat human brains? BRAAAAAIIINS?

This never made sense to me. I mean, after a while, when the zombies gather in hordes and there are few living humans around, you would think they would need any energy they can get and not really discriminate by species or favored body part. Of course, not all zombies eat brains — in The Walking Dead they’ll eat anything, animals included, and the entire thing. (So resourceful.)

Perhaps brain-eating rose as a zombie characteristic because if they ate all of their victim, zombie-ism wouldn’t propagate very far. Gotta leave the prey a leg or two so that they can stumble and limp appropriately and, since zombies are altered in behavior, maybe they’re missing part of their brain. Got it.

Creepy zombie torso explains why she craves brains

Perhaps my favorite zombie movie is Return of the Living Dead, featuring punks fighting zombies (with a great soundtrack to boot). According to Wikipedia, this is also the film that debuted the zombies craving brains, with their stereotypical yell: “BRAAAIAIIINNNS!”

While hiding out in a funeral home, the humans manage to capture a decaying zombie torso — which I believe is given a tribute in the first episode of the Walking Dead (see how I did that? full circle!) — and they tie her up and ask her about her habits. “Why do you eat brains?” She told them that it helps her to cope with the pain of being dead. “I can feel myself rotting… [Brain] makes the pain go away.”

It’s unclear how exactly this helps — what is it about brains that would dull the pain of feeling your own body rot? But at least it’s an explanation, and, being as obnoxious as I am, for me any explanation in science fiction is better than none.

Zombie biology, Pt. 1: Richard Matheson’s bacterial symbiosis

This is the first post in a 5-part series on the biology of zombies. More info and links to other posts here.

A little girl zombie eats her victim in Night of the Living Dead

The rise of the zombie in pop culture is typically credited to George Romero’s ghouls from his Night of the Living Dead films, whose dead bodies reanimated with a taste for human flesh define our prototypical zombie. Romero doesn’t give a clear cause for their rise from the grave, with a vague mention in a television broadcast of a satellite returned to Earth from Venus emitting radiation. (Radiation could do anything back then!)

In a behind-the-scenes special about the making of the movie, Romero credits its creation to a short story he had written, “which I basically had ripped off from a Richard Matheson novel called I Am Legend” —  a great horror story about Robert Neville, a man fighting for his life in Los Angeles against vampires. But the novel takes the vampire prototype and turns it on its head, with these creatures more recognizable as zombies to us than vampires. They aren’t the sneaky serial-killer types, but are rather stupid and gather in great hordes, and, like zombies, will feed upon one another if they must. (Yes, they have blood!) In an early chapter, Neville reads Bram Stoker’s novel Dracula (as he sips whiskey and listens to Brahms while vampires scream outside his house), describing it as “a hodgepodge of superstitions and soap-opera clichés” compared to his situation at the time.

Most of the standard vampire tropes hold true: they’re sharp-toothed, blood-sucking, repelled by crosses and garlic, and can’t come out in the sunlight. But this is science fiction — there must be a scientific cause for these symptoms! While he’s skeptical of the scientists’ germ theory of vampirism that was proposed before the scientists became vampires themselves, Neville eventually overcomes his “reactionary stubbornness” and gets a microscope. (And Matheson doesn’t leave out the difficulties of microscopy or mounting samples, with Neville throwing his first scope across the room in frustration.)

When he finally gets his slide loaded with a sample of vampiric blood, he is shocked to see a bacterium in the sample — a bacillus, “a tiny rod of protoplasm that moved itself through the blood by means of tiny threads that projected from the cell envelope.” And from there much of the book turns to scientific inquiry with many moments that made me smile, like when Neville so urgently “needs to know!” that he nearly runs out of the house into a vampire horde. Oh, the drive of science! Or when he can’t make the pieces fit into his bacterial model and begins to work himself up into a fury:

He made himself sit down. Trembling and rigid, he sat there and blanked his mind until calm took over. Good Lord, he thought finally, what’s the matter with me? I get an idea, and when it doesn’t explain everything in the first minute, I panic. I must be going crazy.

But over the course of years, performing experiments on captured vampires and their blood samples, as well as doing a lot of hard thinking, Neville manages to explain to himself why the vampires act the way they do. Whether his explanations will be good enough for you is another question.

The bacterial lifecycle

Bacteria from the same genus as Neville -- this is Bacillus subtilis, while he found Bacillus vampiris

“I dub thee vampiris,” he says to himself when he sees the bacteria for the first time. The bacteria live in the bloodstream of their host and require fresh blood to live, living in a kind of symbiosis (described thus by Neville), with the bacteria generating energy for their hosts. But if there isn’t enough fresh blood around, a bacterium will sporulate, building a cell wall around itself to hide out until better conditions arise. When the host dies, these spores disperse, landing on a new host, with the new source of fresh blood reviving the vampiris bacterium.

In the novel, the bacteria were able to spread rapidly through the population due to dust storms, with the wind blowing the spores everywhere and the dust nicking peoples’ skin and thus creating a way into the body.

Neville’s discussion of bacteriophages is a moment of total scientific inaccuracy which I choose to ignore. His bacteriophages, which he describes as proteins that the bacteria secrete when conditions are poor, cause the bacteria to swell and explode, killing themselves along with the hosts’ cells. The thinking must have been that the bacteria need a way to kill their hosts so that their brethren spores can disperse — however a bacteriophage is not a protein, but rather a virus that infects bacteria.

Death by stake — an issue of bacterial metabolism

These vampiris bacteria can live with or without oxygen — aerobic or anaerobic metabolisms. In the bloodstream, they live without oxygen, but the second oxygen hits the system, they become parasitic, killing their host. And here’s where the stake comes in: The key to killing these vampires is creating a hole large enough to let oxygen into the bloodstream, causing the host to die immediately due a switch in bacterial metabolism. And when the host dies, the spores are released — and thus we have vampires exploding into dust. Once Neville realizes that it’s an issue of oxygen and not stakes or their material, he switches his method to simply slitting the wrists of the vampires to let oxygen in. “When I think of all the time I used to spend making stakes!” he says.

And why don’t bullets kill vampires? This is some embarrassing fabricated “science:” The bacteria cause the creation of a “powerful body glue” that seals bullet holes as soon as they are formed. (Though this body glue somehow can’t reseal the wrist slits.) The stake creates a large hole and blocks the body glue from resealing it, which is why they are such a potent weapon against vampires.

Other bacteria-based vampire symptoms

Philip Burne-Jones's painting The Vampire (turn of the 20th century)

Neville read that strong sunlight kills bacteria, which is why vampires can’t go out in sunlight. But without fresh blood, the bacteria can’t create energy — resulting in the coma-like state of the vampires during the day.

One of his first experiments is trying to work out the vampires’ aversion to garlic. After reading that garlic’s potent odor is caused by allyl sulfide, he goes to a chemistry lab and heats mustard oil and potassium sulphide at 100 degrees to create the compound. First he tried injecting it into a vampire — but nothing happened. He expected the bacteria to be killed by the allyl sulfide in a lab experiment, yet again nothing happened! He was so infuriated by this failure of his theory that he downed a bottle of whiskey, broke a bunch of glass, and shredded a mural he painted.

World’s gone to hell. No germs, no science. World’s fallen to the supernatural, it’s a supernatural world. Harper’s Bizarre and Saturday Evening Ghost and Ghoul Housekeeping. ‘Young Dr. Jekyll’ and ‘Dracula’s Other Wife’ and ‘Death Can Be Beautiful’. ‘Don’t be half- staked’ and Smith Brothers’ Coffin Drops.

He stayed drunk for two days and planned on staying drunk till the end of time or the world’s whisky supply, whichever came first.

Yup. Just a normal day in the lab.

He later realized that this chemical in the bloodstream wasn’t enough. It was the actual odor of the garlic that did harm — an allergen that sensitized and repelled the bacteria, and hence their hosts. Tells you something about in vitro and in vivo experiments, am I right?

“The germ also causes, I might add, the growth of the canine teeth,” he mentions once near the end of the novel. Good save, Matheson.

Vampire psychology

Neville wasn’t satisfied by this theory alone — what about the mirrors and crosses?

A new approach now. Before, he had stubbornly persisted in attributing all vampire phenomena to the germ. If certain of these phenomena did not fit in with the bacilli, he felt inclined to judge their cause as superstition. True, he’d vaguely considered psychological explanations, but he’d never really given much credence to such a possibility. Now, released at last from unyielding preconceptions, he did.

Before society collapsed entirely when vampirism was spreading, in terror people turned to religion to calm their fears — The vampires were cursed by god for their sins, and only by accepting god could you be saved! Neville theorized that when these people, now convinced that evil people were condemned to vampirism, were infected by the bacteria and found that they themselves were vampires, they were driven mad. The mere sight of the cross — a symbol of their rejection — made them want to flee due to their self-hatred.

But the cross doesn’t apply to everyone, he noted. He had one Jewish friend that, as a vampire, was not repelled by the cross. But the sight of the Torah made him run in fright!

Mirrors had a similar effect. Having to actually face the fact that they were vampires visually was enough to drive them nuts and induce them to flee.

Ending teaser (but not a spoiler!)

There are a few other awesome biological references in the novel — including the lymphatic system, medical applications and evolution, which I won’t go into detail about here so you can enjoy the read. But I will tease with this quote, especially appreciating that this book was written in 1954.

He looked into the eyepiece for a long time. Yes, he knew. And the admission of what he saw changed his entire world. How stupid and ineffective he felt for never having foreseen it! Especially after reading the phrase a hundred, a thousand times. But then he ’d never really appreciated it. Such a short phrase it was, but meaning so much.

Bacteria can mutate.

Bacterial vampirism: it’s awesome!

I’m no expert, but this was the only example of vampirism being caused by bacteria that I could find. This novel certainly inspired many later stories of plague-based apocalypse and biological transmission of zombie-ism, but, after a few decades of focusing on radioactivity and biological warfare, the genre switched straight to viruses (to be discussed later this week) and never went the bacterial track.

But there’s plenty of good reason to consider bacteria and other spore-based organisms when developing your zombie mythology, especially since there are a number of examples in nature (also to be discussed later). It’s an underexploited transmission mechanism! Get on it, filmmakers.

And one final note — I Am Legend is really awesome and you should read it. Trust me — there is MUCH to enjoy despite what you’ve read here. This is really a novel about human loneliness, perseverance, and our definition of normalcy, after all.

Lazy Sunday Video: A tour de force through the history of life

Posting the lazy sunday video at 4pm: That means it’s an exceptionally lazy day!

But it’s also an exceptional video — one of my favorites that I’ve seen on the whole of the internet. (Gasp!) Piecing together clips from dozens of science documentaries and specials overlaid with stunning music, the youtube user UppruniTegundanna starts out tracing the history of humans, integrating technological and artistic development. Then it takes a turn to beautifully visualize the most severe mass extinctions on this planet before starting from the beginning — from the big bang, formation of the solar system and earth, the first molecules and the evolution of life as we know it.

It’s a lot of ground to cover and it’s so well done. Get ready for 12 straight minutes of butterflies and chills. I haven’t failed to get them each time I watch it, an unquantifiable number of times at this point.

In this video and his others, the artist seems to truly grasp the magnificence of the universe. At its heart, this video is about natural disasters, embracing extinction and death as key to how we got here. In a lovely blog post this week, Patrick Clarkin wrote:

Eugenie Scott, Director of the National Center for Science Education, has written that for many laypeople the notion that evolution is an unguided, mechanistic process implies that “life has no meaning.” However, contrast that view with how many scientists write about nature. The sense of awe and reverence that is exuded is palpable.

And this video exemplifies this — true awe at the fact that we exist at all.

Saturday procrastination update: science comics!

Right now, I’m working on a paper for a class I’m taking on the intertwined histories of science and religion.  Well, when I say “right now,” I really mean an hour ago, and in the foreseeable future.  For I’ve taken a break to read INTERNET COMICS!

Here are a few science-related comics I thought you might enjoy.

The first, from Hark, a vagrant, on Watson and Crick’s grand discovery, theft, and sexism:

The second, from Saturday Morning Breakfast Cereal, actually relates to my paper topic: how the Gaia hypothesis provided a scientific framework for the environmental movement (ecotheology in its extreme form), which it reframed in Judeo-Christian terms.  That’s our man, James Lovelock, the guy who came up with the Gaia hypothesis, in the bottom panel.

Last is BANG!, a full-length comic book (viewable online for free) describing the science of the origins of the universe.  In rhyme!

Enjoy these, and the weekend.  Back to the grindstone…

The alien landscape of your cells

Jessica over at bioephemera alerted the world that the GE Healthcare IN Cell Imager photo contest winners had been announced.  And looking through these photos sent chills down my spine.  (I was eating ice cream simultaneously… But, no, it was probably the pictures.)

As you can see, the pictures show various patterns of fluorescence.  A scientist can selectively stain parts of cells with fluorescent markers  – using antibodies, for example – to study their locations, or even use the brightness to measure the amounts.  (In the lab I’ve used fluorescent antibodies to stain protein residues, and I could even see the brightness without film or a microscope in a dark room.)

This here on the left is a picture of brain tissue.  The blue parts are its DNA, while the green and red are two types of neurons, or brain cells.  They’re all stringy and tangled looking so that signals can be transmitted quickly through the brain.  I’m a sucker for pictures of neurons because they look so alien compared to normal cells.

But, truly, all life on the cellular level is alien.  That’s part of what is so inspiring about viewing image collections such as this one: how can we imagine that this is what is going on inside of us?

It took me 6 years of studying biology before I truly understood that CELLS MAKE UP MY BODY.  I know, it seems like an obvious fact.  But it’s one thing to read a biology textbook and label a drawing of the parts of a cell, and another to fully grasp the concept that trillions of these things compose my body, undergoing processes of which I am completely unaware.  That once I was one cell – and now not only do I contain multitudes, but many different types.

I want to share my first moment of this realization with you.  I was a sophomore in college taking a genetics course with my main man, Stephan Zweifel.  To be perfectly honest, I was completely overwhelmed by the class.  (The thought of two DNA strands overlapping and switching their genes in a cell was way too much for me to grasp at the time.)  But one day he showed us a video put out by Harvard showing the life inside of a cell.  Maybe it was the mesmerizing music, but I was drawn in entirely, struck simultaneously by two emotions.  The first was horror at my inability to follow the video, identify a single molecule, while my classmates called them out around me.

But the horror quickly dissolved into complete and utter awe.  I sat there slack-jawed as molecules assembled and disassembled themselves into elegant stalks (actin and microtubules, the beam-like skeleton supporting the cell), a bow-legged molecule hobbled along a pole dragging a huge, watery balloon behind it (a motor protein guiding a vacuole to the transportation center of the cell), and proteins suddenly stood up erect, as if for the first time (a dramatic conformational change).  It didn’t matter that I didn’t know what was happening or why.  All I knew is that something complex was happening on screen, and that these things happened inside of me.  Constantly.  And I had never noticed.

How could my own body be so alien?  I could have been watching a sci-fi film.  And it hit me: there is beauty on this small scale.  There is art that had been perfected for billions of years, that continues to evolve.  And I had the tools to understand it if I could only apply them.

And that’s how I began my journey to try to become a science dilettante.

But seriously, folks.  Look at lots of pictures and movies about cells and molecules.  Get totally freaked out about your body and its alien landscape.  Take comfort in the fact that no one will ever fully understand it and find joy in being overwhelmed by all the things we don’t know.  That’s what being a scientist is about, as far as I’m concerned.

Endangered species awareness: 2 cool projects

Endangered species were the first type of conservation I remember learning about.  I did a panorama of the black-footed ferret in 3rd grade.  A project on the manatee in 4th grade led to a sirenian-obsessed pre-adolescence.  These are cute animals, and we are destroying their habitats!  WE MUST SAVE THEM!

Endangered species are a great way to connect a public, which may not be interested otherwise, to conservation efforts.  It’s a near-tangible way to pinpoint a specific problem, a specific animal even, and get people involved.  Some conservationists argue that this isn’t a good method, that the focus on CMF, or charismatic megafauna (such as the endangered whales, tigers, lions, manatees, etc.), ignores the smaller and uglier microbes and insects, which are going extinct at a much higher rate.  But, hey, you’ve gotta start somewhere!

Seychelles Sheath-Tailed Bat by Molly Schafer

The Endangered Species Print Project was started by the artists Molly Schafer and Jenny Kendler, who met at the Art Institute of Chicago and bonded over “nature-geekery.”  After years of art shows filled with works based on natural imagery, they decided to start a project to help save some of the animals that inspired their work.

The ESPP releases prints, the sales of which go towards specific conservation organizations.  Each print stars an endangered species and the number of prints of each work corresponds with the number of animals left remaining in the wild.  For example, there are only 37 prints available of the seychelles sheath-tailed bat, and 222 of the madagascar fish eagle.

By limiting the print-editions, there is a reaction in the buyer to want the rarest print (as is an art-buyer’s instinct), accompanied by the creeping realization of what the rarity of that print means, and of how distant our lives are from these animals’.  Sure, we can buy a piece of art that is a symbol for a single animal that exists in the wild; this art can donate money to help save this specific animal; but in the end, these species are nearly gone from the planet, and far more needs to be done than buying a piece of art.

That being said, this is a wonderful project to support, as it spreads conservation awareness while donating money to good causes.  Buy prints here for $50 a pop (no matter the print/wild quantity).

Extinked, which took place in November, involved the tattooing of the endangered species of the British Isles on chosen human “ambassadors.”  Detailed scientific drawings were made of the species, and common citizens applied to the artists for the honor of being blessed with the drawing of the specific animal for life in the form of a tattoo.  Even if the species does go extinct, it’s form will live on in the skin of at least one Brit for another 100 or so years.

And isn’t that one purpose of art?  To commemorate a certain event or person or time?  I like to imagine the effects of this project much like the living books in Ray Bradbury’s Fahrenheit 451, where people would memorize the text of books and teach it to one more person before they died to keep the book alive through the book burnings.  Pass on your extinct animal to the next person, so that at least a glimmer of prior biodiversity can be remembered by a small group of people.

Quit Smoking: You’re Lucky to Even Exist

Most smokers know exactly what they’re doing.  They know their chances of cancer, the bad smell, the reduced lung capacity.  No matter how much new research surfaces showing that smoking is bad for you, it doesn’t seem to have an impact.

Some agencies have gotten more creative with anti-smoking ads, combining science and anatomy into images to demonstrate what is being done physically to a smoker’s body, such as ashtrays showing lung x-rays, variations on ashen organs, or, my personal favorite, matches as sperm with the headline “smokers make poor swimmers.”  [For a compilation of advertisements, see this post from the design inspiration.]

INPES, Institut national de prévention et d’éducation pour la santé or France’s National Institue for Prevention and Health Education, just released an advertisement that takes a different angle: why would you knowingly destroy your life, which in itself only exists by a slim chance?  The video traces through scientific history — the big bang, rise of life, carbon and nitrogen, dinosaur extinction, down to the moment of fertilization.

Instead of coming off as preachy or condescending, the ad’s wonder at our existence is inspiring for the smoker and non-smoker alike.  I don’t know how truly effective it is as an anti-smoking ad, as most smokers have already fully accepted that they are taking a chance.  However, I would fully endorse this as a general public service announcement to make people aware of how lucky we all are to be alive, and to appreciate that fact alone.

Kevin Van Aelst, Chromosomes, 2005, digital C-print, 20 x 24

I have this picture hanging next to my computer at work, and no one has ever recognized it for what those lil chromosomes are — gummy worms!  Everyone always asks me, “oh, that looks cool, what stain did you use?”

Kevin Van Aelst makes art that appeals to me.  A lot of it references biology in some way — such as his egg mitosis, gum digestion, or coffee clouds.  In all cases he takes a common object such as food, clothes, or bodies, and applies a scientific or mathematical concept to it.

This is the sort of science-art that really appeals to me.  Artists who take these sometimes complicated or seemingly inaccessible ideas and make you see them all around you.  It makes things like cell division or DNA, which can be hard to believe even occur, seem easy or natural.

Please go to Kevin Van Aelst’s website!
