The Doors of Perception

“If the doors of perception were cleansed every thing would appear to man as it is, Infinite. For man has closed himself up, till he sees all things thro’ narrow chinks of his cavern.”

7 Habits of Highly Successful Invaders


I was driving home from work, appreciating that the switch has been flipped, and suddenly! Spring. The greens are moving all misty into view, and predominantly among them here in Southern Ohio is the Amur Honeysuckle. I was contemplating this, and how that trait is one of the things that makes it a highly successful invasive species, and it dawned on me that there are more ways to invade than are portrayed in movies about aliens. Sure, overwhelming military force is one way. But what other things have species done here on Earth that enabled them to conquer and victoriously rule the forest field stream continent? Read more

Science Fiction in our Genes

I wrote earlier this week about science fiction, adaptation, and the human species over on my blog. in a nutshell, I’d written earlier about genes and how animals raised in captivity adapt to being in close quarters so quickly that it’s not really a viable option to raise an endangered population up to replace wild populations that are in danger of extinction. So what does this have to do with humans? Well, the conversation went something like ‘people who like to live in cities are weird’ (I’m shortening and paraphrasing) during a discussion about the coasts of the US, and how they have a tendency to vote a certain way. But, if you think about it, and I do, urbaniztion of a population does indeed do things to it. Similar things, I think, to the effects felt on a captive population of, say, butterflies. The butterflies get smaller wings, heavier bodies, and the ability to lay more eggs. So in effect they are going to do well in a cage where they can’t fly far, and would be easy prey for predators if they were put out of their nice safe cage.

Scientists are studying the effect that urban areas (generally defined as >300,000 people) have on plant and animal species. It’s no real stretch to imagine that living in a metroplex would affect humans as well, especially the poorer, less mobile parts of the population. And this is without even moving into the realm of science fiction. These studies have seen the effects of adaptation in as little as two generations – in my original article I was working off the premise that large effects of  captivity were seen in Drosophila in eight generations: in human terms, 150 years. But two? A mere 30-40 years? (yes, thirty. Look at average primapara age for the inner-city populations).

All this is native to our design for adaptation and evolution of the genome, the in-built system to keep a species thriving in changing environments. If you don’t adapt quickly, you die – which was a larger part of what led to the passenger pigeon extinction than human predation on that species. Now, how about human tinkering with our own genes? We can do it – we’ve known that for a while, gentle readers. But a new paper on Crispr tells the tale of genes switched on inside an adult allowing that model organism (a mouse, in this case) to express genes they had been unable to do before, which led to the self-treatment of diabetes, kidney disease, and muscular dystrophy. This is exciting on so many levels, one of which is that this was done without having to completely break the DNA (a double-strand break) which means that the inadvertent introduction of mutations is not a concern.

Now, leap off this mudball and into the realm of science fiction. We see that if we do not maintain genetic diversity and gene flow between populations, we risk extinction. The ability to quickly adapt and overcome has long been a human realm. But what, as our populations grow larger and our urban areas soak up the majority of the humans on this planet, will happen to that diversity? What if we became like the passenger pigeon, and when sudden catastrophe came (a pandemic, an alien invasion, what-have-you) we were unable to adapt? The answer lies in the stars. But to get there, we’re going to have to adapt again and again, and our populations, like the urban rats of New York, will evolve and differentiate. Not enough to become separate species, unless we really start tinkering with Crispr… although as writers and speculators, we know that’s going to happen, don’t we? Humans will experiment, and they will experiment on themselves. I mean, it’s only a matter of a few years since the theorist about Heliobacter pylori decided to prove his hypothesis by drinking a beaker of that pathogen and giving himself ulcers. And another one ingested internal parasites on purpose to prove that they would put his autoimmune disease into remission. We’re crazy, we humans.

Which means that to write science fiction we have to think crazy, like a fox. To imagine the weirdest thing we can, and then take it a step weirder. There’s a whole field of stories that suddenly seems prophetic as we begin to truly understand the tools we have now, and the reality of epigenetics. Lamarck, who proposed the giraffe’s neck had become so long because it was necessary to reach the higher leaves (the ones out of reach of the eland and the gnu, which makes me think of Kipling’s stories), was laughed out of science when Darwin’s theory was all the rage, but in the long run it turns out that he was more right – and our genes more complex – than scientists at the time could possibly have imagined. Now, keep in mind that although we are now able to manipulate our own genome, and we have begun to grasp that natural selection is not always the random pattern once theorized with the epigenetic understanding that we are shaped by our ancestral diet and environment, we still do not fully understand what genes do.  there are a few genes we can point out and say x does y. However, the vast number of them interact in complex and mysterious ways. We can’t just say, snip that gene out and cure cancer! because that’s not how it works.

Which means that in terms of story and speculation, we have worlds of room to draw conclusions and create plots that could be possible, or utterly wrong, but it’s so much fun to take the bleeding edge of science and play it out into what might be. What’s next?


I’ve been reading science journals a lot, while I’m waiting for reactions at work. I need something to do, and mostly they are work-related. But I came across an article which delighted me, and I had to share it with you all. There aren’t many places where I can really let my inner book geek hang all out, but this is one of them! 


It used to be that in order to test a book for science, you’d have to destroy a little bit of it. Somewhat obviously, museums and collectors reacted to the thought of this with horror. However, with the advances of technology and ability to get down to the molecular level with testing, it’s now possible to use erdu for determining what skins vellum was made of…


Well, maybe not vellum. It depends on how you define vellum, versus parchment. In general, vellum was higher quality, formed from calfskin, and was believed to have been most sought after from stillborn or newly born calves (3), which modern science has shown isn’t necessarily true. Instead, through studying the proteins, scientists learned that technology of the Middle Ages was better than we assumed it was. They were able to form onion-skin thin vellum from animal skins, leading to a proliferation of ‘pocket bibles’ in the 13th century. We talk about print runs, in this era of automation and mass production, so to put this in perspective: they postulate that 20,000 of these pocket bibles were produced. That’s an amazing amount of work, and animal hide. Scholars have wondered for years how they managed to sustain that level of production, until they were able to apply science to the books. This disproved both the theories about vast herds of cows being depleted through abortion of calves for making books, and other theories about the use of rabbit or squirrel skins (2).


I love that word: erdu. It’s so cool and weird and it means the little bits you have left when you use an eraser on paper. Mostly, the bits are made up of whatever the eraser is made of (they are not India Rubber any longer as they were in the days of Kipling’s schoolboys, which is sad, but manmade polymers like PVC), and whatever was on the sheet of paper the eraser was rubbed across, gently lifting up and encasing in the erdu. That ‘other’ material is what scientists are testing from old books.


It’s not that they are erasing anything from the page, simply using what is called a ‘dry cleaning’ method to remove the built-up crud of centuries, by creating an electrostatic attraction with the PVC eraser that lifts away the molecules. The book the article highlights dates back to the 1300’s and that’s a lot of time for stuff to accumulate. From the erdu, they were able to learn that this one book was made up of the skins of two species of deer (the cover), 8.5 calves, 10.5 sheep, and a half of a goat (1). Which is pretty amazing, but also weird.


It gets weirder. I was vaguely aware that in some religious ceremonies, you kiss the book. Which action, as you can imagine, leaves a residue of bacteria behind. Can you imagine having the kiss it right after some guy with a snotty nose? Ewww… From these pages, scientists are able to isolate species of bacteria they associate with human hosts, and also DNA (1). However, the pages are ones with oaths on them – you swore, and then you kissed the oath to prove how much you meant it. We don’t do things with that sort of gravitas any longer, do we? Of course, we also know those bacteria are teeming around on the page waiting for the next pair of lips to call home.


While they can’t extricate individual DNA from those pages used by many to prove their devotion, they hope to be able to from a book that was owned by only one person. This could help them build a profile of the person, right down to hair and eye color. Other scientists are more interested in sampling worm poop – they want to know what species of beetles bored through the priceless books and left only their droppings behind in neat tunnels (1).


We have come so far, in these last centuries. From parchment, papyrus, vellum… to rag paper, and pulp paper, and now to electrons leaving a fleeting impression on screens. Even if you all are kissing your computer screens (I don’t want to know!) or slightly less gross, sneezing on them, chances are some as-yet-unborn scientist is not going to be swabbing it for your DNA. Much less being able to tell what you were reading.


For fans of my writing, I’m doing a cover reveal with snippet and blurb for my upcoming novella, Snow in Her Eyes. Let me know on my blog if you like the cover!

Take two aspirin…

It’s been an eventful week, and I found myself lying here this morning thinking. I’m far from home, out of schedule (this post was supposed to be written yesterday) and have a headache. It’s all worth it, though. My eldest graduated from highschool last night. She’s a fiercely independent soul, and will go far in her studies at college.

But that’s not what I wanted to write about. Toni Weisskopf shared a photo on Facebook of a computer module absolutely infested with an ant nest, seething with eggs, and her comment was that she’d like to see more stories like that in science fiction. It’s an excellent point. I can’t tell you how many stories I’ve read ( and written) where the tech performs flawlessly. Which does happen. There are also stories where it doesn’t, but how many can you think of where the characters have to deal with an infestation? How would we prevent that, control it, and what kind of adaptations will we see?

I’d run across an article recently about bacteria which will break down plastics that were formerly thought invulnerable. Then there was another one speculating about why less plastic (by an order of magnitude) is found in the ocean than projected, and the discovery of novel bacteria on that plastic. The concern was focused on reducing pollution, but what happens when bacteria evolve to eat stuff we want to stay intact and functional? The stories about nanotech making gray goo aren’t that far off from what bacteria are already capable of – only fortunately they are not so fast to act.

We can’t escape our invisible (to the naked eye) friends. Microbes cover every inch of us, and our surroundings. We can only culture a tiny fraction of them in the lab, we’re still working on understanding the ecology of our own “inner gardens,” but we are already harnessing the power of their replicative properties for good… With the advances in molecular genetics we can use bacteria to copy/paste stuff we want, like drug ingredients and human proteins. With enough time and development to move beyond ‘we can do that’ to ‘and cheaply!’ the future looks very interesting indeed.

So those two aspirin I want might someday be extracted from bacterial sludge. Trust me on this, if you think that’s gross you don’t want to contemplate where some modern drugs originate. Not all of them are turned out from sterile molecular synthesis. Heparin (an anticoagulant) involves tons and tons of pig guts every batch made. Think about this in terms of going to space. If we don’t come up with highly efficient methods of synthesis, there are going to be problems.

It’s fascinating to extrapolate from current science, to bleeding edge, and beyond. As a science fiction author, it’s an exercise in developing my stories into something approaching hard science. As a baby scientist, it gives me food for thought about my career (and my daughter, who plans to study molecular genetics) path in the coming years.

Will we ever harness the power of Leeuwenhoek’s animalacules? We already have, now we just need to make that more efficient. Will they slip their leashes and turn on us? Well, yes. They already have, many times. The history of pathogens and disease goes back before the dawn of history. We can read it on the bones left behind, long before men scribbled on pages or chipped runes into stone and pressed them into clay. Speaking of which, I found a neat book on KU, for the readers like me who appreciate an in-depth look at science and history – Old Bones: a brief introduction to bioarchaeology. 


Making it all Up

This post is going to be a little late, and thank you for your patience – I was under the weather and although the clouds are thinning, I’m still not in sunshine. Actually, I woke up this morning and had forgotten it was Saturday, and it wasn’t until I was talking with my friend that I realized I didn’t have a post. Or a topic. Or, really, much of a brain. Fortunately, we’d been discussing her writing work-in-progress, and when I brought this post up, she suggested a topic.

How to balance hard science and fantasy in writing?

There’s a bit of an assumption about writing fantasy I run into from time to time. ‘That’s so easy to do, you just make it all up.’ I suppose it’s possible that there are fantasy authors out there who don’t bother with any research, they just make it all up. But reality as an underpinning to fantasy is essential to my reading pleasure, and I suspect strongly that this is the case for most readers. So the ability to blend science with fantasy is essential. You can’t disobey the laws of physics because ‘it’s magic’ any more than you can in Space Opera, unless you want your books to take regular flying lessons.

The friend I was talking to – I’ll call her Thing 2, since that’s her nickname in our group, and using her real name is confusing here – was commenting on the fact that she couldn’t find images as generated from the latest night-vision system. Since it’s not legal for civilians and all. She’s trying to research her work, and to blend science in with her fantasy. She’s doing it right. Her imaginary world isn’t going to have capricious magic use that exists for the convenience of her plotline. When vampires show up, they won’t be ignored and dismissed, actual science will be done on them and their traces.

This is what I like to read about. Magic that is limited, has a price to use, and it’s not like turning on a tap. Well, if it is, it’s with the understanding of where the tap is connected to pipes, and a pressure tank, and a well, and the well WILL run dry if you try to pull out too much, too fast. Just like in the real world, magic could be handled like chemical reactions: you can react some substances with others, bot not all. Reactions should be endothermic or exothermic. A catalyst will help the ‘spell’ get over the initial activation energy need to make it proceed faster (or proceed at all, in some reactions). if we’re going to keep this chemistry as magic metaphor, we should also keep in mind that the ‘water’ coming oout of our tap matters, a lot. You don’t use regular tap water for chemistry, it’s got contaminates in it, and ions and goodness-knows what-all. No, you want deionized water that is from a controlled source so you aren’t reacting with something unknown like calcium carbonate. You also want clean glassware. Some of these fantasy novels with their oddball ‘organic’ wood or stone containers *shudder* I don’t know what you’re going to get out of that and when was the last time you read about a witch scrubbing and sterilizing their workspace? Heck, half the hurdle in Analytical Chemistry is learning how to properly wash dishes. Also, some magical reactions will be more, ah, energetic than others. And if my fantasy writer readers want to play with THAT concept, check out “Things I won’t Work With” a series of chemistry blog posts.

Pulling myself reluctantly away from that metaphor (what? I really like chemistry) I’m not sure that’s what Thing 2 wanted to concentrate (heh, heh… concentrated vs dilute magic. Back away from the Chemistry jokes, Cedar) on. Science, in the purest form, is the study of the universe using mathematics and measurement. This is done with observations, experiments, and hypotheses that can be tested, repeated, and proven. I don’t see any reason why a well-written fantasy can’t adhere to the same rules of the universe as our known sciences. It does mean the author should have at least some grounding in basic science, though.

My point, if you managed to follow me through this odd ramble, is that you can’t just make it all up. Not an make it into a good book with a solid story. If you want to blend hard science and fantasy believably, you have to do your homework. Thing 2 is on the right track, and I am hoping she keeps at it – this would be her debut work, and it’s got a lot of promise. I do enjoy a well-done fantasy, especially an urban fantasy that pays attention to the rules of the universe and doesn’t break science without a very good reason. Or some kind of explanation afterward when the main character demands to know what the &*^$ that was!

Operating on limited brain, I can only think of two titles offhand that did a really nice job of pairing the two fields of magic and science. I am sure you all can come up with more, and please do. The first, and highly recommended, is the Lord Darcy series by Randall Garrett. The second much more recent is Julie Frost’s Pack Dynamics which gets into (lightly) the mad science of vamps and weres.

What can you suggest for blending hard science and fantasy in a story?
