So, there IS a new David Quammen book! This one deals with the crossover of infectious disease into humans; a fascinating, terrifying, and all-too-common process called zoonosis. Diseases such as bubonic plague, swine flu, HIV, and Ebola fall into this category. It’s important to note that transmission by an organism doesn’t make a disease zoonotic; rather, zoonoses involve a “jump” of a species-specific pathogen to a new species (in this case humans). Swine flu is a good example. Normally, we don’t catch the flu that pigs catch — the virus is great at infecting pig cells, not ours. But when that influenza virus mutates (which it does often), some of those mutated versions may be able to infect us (note: some of those mutations might also be harmless to us; some mutations will render the virus ineffective entirely — but we don’t hear about those versions. This is natural selection, of course.). This situation can be especially problematic because that recently mutated virus, in addition to being “new” to the world, is also totally “new” to our immune systems (advantage: virus). Throw in the fact that we’re putting ourselves in contact with more and more potential “new” pathogens all over the world (travel, exploration, destruction of rain forests, etc.) and we end up with a lot more potential diseases to combat. My seventh graders do a project on infectious diseases after studying bacteria and viruses, and the subject of this book ties in nicely with that project. So, in addition to new books this fall from Chabon, Helprin, McEwan, Ruhlman, and Kean, now I’m looking forward to finding some time to read Quammen’s “Spillover.”
Here’s the trailer for the book from the publisher, W. W. Norton:
I’m tempted to lean towards the overblown and pronounce something like, “Everyone should read this book.” But I realize that not everyone is going to read it, and that’s okay. It’s non-fiction, pretty dense and scientific, and it’s hugely interesting. Maybe you’re not into that. It’s brilliantly presented, by the way. Parts are thick, with a multitude of hormone and receptor names, other sections with references to neurological and psychological research that spreads over the last century, and parts could be construed as depressing (not in the clinical sense of the word), but only if you stop halfway through the book, because there’s hope at the end (more on that later). Sapolsky’s writing is engaging, detailed, at times humorous, and it’s accessible, despite the depth and complexity of the subject matter.
I do feel like all kinds of people should read this book: if you are a teacher (and not just if you teach science); if you have kids of your own; if you’re married; if you work; if you’re curious about how the brain works; if you’re curious about stress; if you have stress; or if you really want to know what stress does to your body at the chemical and biological level… the list goes on.
I didn’t know about Robert Sapolsky until just recently, when I read that his Introduction to Human Behavioral Biology course at Stamford was available to watch online for free (thanks to OpenCulture: Biology That Makes Us Tick 3-28-11). I’m curious about his other books, A Primate’s Memoir, and The Trouble With Testosterone, because I really enjoy his writing style, (and I teach biology, so I happen to be interested in those topics). I also find him to be a fascinating lecturer. And once you watch the intro to Behavior Bio linked above (or watch the lecture on stress and depression below), you can absolutely hear his voice come through his writing. I imagine that when you write a book about a topic in your field (and revise it twice) that it becomes pretty familiar material. Whether it’s explaining the subject in front of a class or presenting his ideas in writing, he lays the case out clearly and persuasively (down to the same examples and phrases). The lecture below pretty much summarizes chapter 14 on stress and depression, which is staggering:
It’s incredible how far-reaching are the effects of stress and its attendant chemicals. They can save your life if you happen to be running from an actual lion (like the zebra of the title), but the case of humans is a bit more complicated because we tend to overthink things; the same chemical stress-response can get your hormones and body all worked up if you’re just anxious about running from a lion (or running from some metaphorical lion in your actual life). Elevated levels of glucocorticoids (a major focus of the book) can wreak havoc on your heart, blood vessels, reproductive and immune systems, sleep patterns, and general well-being. Elevated levels of stress hormones have been shown to have the same effect on your body that years of aging has. Oh, and they can also shrink your hippocampus and screw up your memory. Great.
But there’s hope.
The last section of the book is on dealing with stress. It’s possible. People actually do it, effectively even. And with the goal of “aging well” — not letting stress beat you down — Sapolsky presents some suggestions. Some of this stuff is unavoidable, due to the circumstances (genetic, environmental, and socioeconomic) that a person is born into — we don’t have much control over those things, and they are major influences (or potential risk factors, frankly). But under the heading of “control what you can control” he presents coping strategies that include exercise, maintenance and growth of positive social relationships (which do make a difference), meditation, religion, social support networks, and the importance of maintaining perspective. It doesn’t really end with fluff, and I hope I haven’t made it sound like that. It’s not a self-help book. Throughout the book Sapolsky presents clinical research, case studies, and work with rats and baboons that illustrate in remarkable detail how our brains and hormones (and those of all mammals, really) work. I feel that understanding the ways that the body deals with changes in the outside world (stressful things) can help influence the way we approach them. It might be tough to tell a “type A” personality to keep an even keel, but it turns out that it’s one of the more important things you can do.
A quick post to say that the Learning & the Brain conference (Web-Connected Minds) last weekend in Arlington VA was terrific. A whole lot to think about. And in order for me to process all the information, I’m going to start working through my notes and get some stuff out here over the next week.
First, I was happy to meet some new colleagues in the field. Conversations and emails swapped during individual sessions, new connections made through the Twitter (search hashtag #LB32 for the stream of tweets from the conference), and a face-to-face “tweet up” on Saturday night made the experience all the richer. A tangible benefit of the workshops, keynotes, and conversations is that my stack of books-to-read has grown tremendously. I started an open Google Doc to get all the recommendations down in one place, and I got plenty of input from presenters and other teachers at the conference. Please take a look, add your own suggestions, or comment on the ones that are there (or write in the Comments section below). I haven’t read all of these books, but I’ll try to work through some of them this summer. I’m going to start with Play by Stuart Brown, and Brain Rules by John Medina. I’m also interested to read Cathy Davidson’s Now You See It after her fascinating talk on Sunday morning.

Also, Maureen Devlin (@lookforsun) writes the blog Teach Children Well and she put out a tweet this morning, looking for teacher summer reading suggestions. Feel free to chime in there as well.
Free Stamford course on human behavioral biology by Richard Sapolsky. A fascinating course, dynamic speaker, and free through iTunes or YouTube. Found via @openculture: cultr.me/gg92Hk
To be filed under “fascinating reads of all kinds” and “things that make you think,” check out Brain Pickings, which is mostly book-related, always interesting. Also see their companion Tumblr bookshelf for a quick look at all the books they talk about.
In addition to the Virtual Urchin simulation, I’m interested in a few more that were mentioned in Technology in the Secondary Science Classroom (Bell, Gess-Newsome, Luft). And as we understand that online and computer simulations don’t replace first-hand experiences, they do represent great supplemental material.
I teach a seventh grade class that includes Life Science and Environmental Science components, and a 9th grade Biology class. I’ll talk more about supplemental materials for my 7th graders with online data sets (post forthcoming). But there are quite a few that I’m looking forward to exploring more with my biology students.
I’ve found Cells Alive very unseful in the past when discussing (and illustrating) cell organelles, cell cycle, mitosis, and meiosis. The interactive portion of the website, including the animations and schematic diagrams, are clear and helpful to students.
For other topics in biology, I might consider trying ExploreLearning.com, although this is a commercial website, and I’d have to balance the benefits of its simulations with the cost of subscribing. It does look like they have a ton online. Here are the selected topics in Heredity and Genetics that they offer. I might consider trying the 30-day trial during that unit to get a feel for it. Does anyone have experience with this site that they can share?
I need to write these things down before I forget them. I actually typed them first into a catchall Google Doc I’ve started called “Before I Forget.” (That document has notes on everything from books I’d like to read and music I’d like to check out, to what we’re having for dinner on Thursday night when friends come over.) So most of that list won’t be of any benefit to anyone but me (although parts would be interesting to some). But I digress…
Here are the things I’d like to follow up on after tonight’s #scichat (Tuesdays 9pm; Twitter):
Using a Pecha Kucha model to help students work towards more effective presentations – 20 slides, 20 seconds each. It doesn’t work for every presentation, but I really like the model. You could modify it to fit your class or project (10 slides, 20 seconds each; 10×10; you get the idea). Several teachers mentioned that they limit the amount of text allowed on a given slide. I find this incredibly helpful for 7th and 9th graders.
Revisit Prezi this year – good presentations, bad presentations; how to make a good one? I signed up for an account last winter and played around with a presentation to introduce Cell Respiration, but I ran out of time before the unit started. Revisit.
Twitter #APBio chat for Mondays 8-9pm EST. I don’t teach AP Bio, but I might listen in.
Read “The Visual Display of Quantitative Information” by Edward Tufte. Called “the Strunk & White” of visual design. Are there elements of this that could be helpful in teaching my students to communicate effectively with visual media? I think there might be. Added to the book pile…
I missed this when it first came out on PBS in Nov 2010, but a colleague just sent me the link to this video (Thanks, Caryn!), which is a companion piece to the book The Wolverine Way, which I wrote about back in October.
