So do I stick my head into that glass-enclosed rectangular box? Will it fry my brain? Or will the damage show up in 20 years? Will my head come out looking like those primitive shrunken heads that repelled and fascinated me as a child?
I’ve volunteered to have my head 3-D printed, and am checking out the equipment at the State University of New York. As it turns out—great relief—I don’t have to stick my head into the box after all; that’s where the “printing” occurs, not the scanning.
The professor tells me to just sit upright and stay super still on a chair for a little over a minute, while his assistant uses a hand-held scanner—making several passes of the sides and top of my head and neck from about 30 inches away.
In a couple minutes, the glass box starts to make noise and comes alive. The “printing” begins. For the color of my little sculpted head, I’m given a choice of red or white. Red seems a bit creepy, so I go for white. The plastic substance is long and cord-like, about 1/8 inch in diameter, and wrapped around a big spool at the back of the printer. One thin white layer after the other is laid down. It builds up, and slowly a tiny replica of my head begins to take shape. Half an hour, and it’s done.
Sure enough, this looks like a miniature Roxie, about 2 inches high, with a flat back where it lay down on the printer, although the machine appeared to have quit just before it reached the tip of my nose, which is kind of cut off.
So what can be done with this new kind of printing? Well, it is already being used in dentistry for making crowns. Jewelry can be created from metals, even gold. You can actually make plastic guns using this method. Unfortunately (or should I say fortunately), they don’t work very well—the plastic gets distorted rapidly from the heat and action of shooting a bullet.
But maybe the most fun is making food. Nursing homes in Germany are taking pureed food and making it into appetizing shapes. NASA is researching making 3-D pizza in space. Instead of white plastic maybe I should have asked for chocolate—and turned myself into a delicious dessert.
Roxie and her mini-me.

Writing a recipe is harder than it looks. I found this out when a children’s magazine editor asked me to add a recipe to my article about eating insects.
First, I thumbed through my recipe file mentally substituting bugs for a vital ingredient. Mushrooms stuffed with millipedes was out. (Most kids don’t like mushrooms.) I nixed beetle sausage, also. (Too much chopping and frying in a hot skillet.) Flipping to desserts, I chose toffee. I could substitute bugs for nuts.
After my trip to the grocery store for butter, sugar and chocolate chips, I visited the pet shop, and asked for a cup of mealworms, which are fly larvae (also known as maggots, but that’s not very appetizing). The man handed me a little carton that looked like a Skippy cup of ice cream. I wrote that down because I would need to pass that information on to readers who, like me, had no clue how to purchase creepy-crawlies.
With all the ingredients on the counter I recorded each step:
After that, I was on familiar ground blending butter and sugar, and sprinkling chocolate chips.
I called my concoction Toffee Surprise, and taste-tested it in a large group setting where peer pressure encouraged full participation -- my mother’s birthday party! The verdict: The toffee was yummy, crunchy, and sweet with a subtle earthy aftertaste.
Although I don’t plan on cooking more edible vermin, I did learn some important rules for writing a recipe: Choose a food that is reader-friendly; be aware of your readers’ abilities and safety issues; record every step in order; pay attention to even the smallest details; and prepare it yourself so you can work out the bugs (no pun intended).

Have you ever wanted to tell your life's story? It's not as easy as you think. Here are some tips that can make it easier.
First, realize that you can't tell your whole story. Not only will you bore your readers, you'll probably give up before you write a quarter of it. Instead, choose a theme—something that's been important to you and that interests you about your life. Here are a few examples:
* The story of you and your favorite hobby.
* Your experiences with your favorite—or least favorite—pet.
* Fun times you've had with your dad, mom, or best friend.
* The three scariest things you ever did.
* Your best/worst school year.
In my memoir, Snakes, Alligators, and Broken Hearts—Journeys of a Biologist's Son, I decided to focus mostly on my relationship and adventures with my dad. Narrowing down my story not only led to a better story, it made the writing process much less overwhelming. This kind of "slice" of a life is called a memoir. In contrast, when someone tries to tell their complete story, it's called an autobiography. Usually, the only people who write autobiographies have invented electricity or landed on the moon—or they are running for president!
A second tip for telling your story is to pick out certain characters and let the reader get to know them. When writing my memoir, I could have said a little bit about a lot of different people in my life. Instead, I chose just a few and tried to tell more about them. This lets readers get to know the people in your story—and care about your story more.
One last tip is to leave out the boring stuff. When you start writing, it's tempting to include every detail. Instead, start your story where it really gets interesting. For instance, don't begin with, "On my first day of school, I walked to class." Instead, you might start with, "When I looked in the cage, I realized that our twelve-foot long boa constrictor had escaped!" Just because it's your story doesn't mean it shouldn't have a good plot and plenty of action. Focus on topics you'd like to read about—even if you didn't know you!
After reading these tips, you might be asking yourself, "Can I write more than one memoir?" The answer: absolutely! So dig in, have fun, and tell your story. You, your friends, and family will be glad you did.
To help your story be more interesting, focus on one thing. For my memoir, I focused on my relationship and adventures with my dad. Here, he is graduating with his doctorate degree from U.C. Santa Barbara
Both my dad and I loved reptiles, so I told a lot of stories about them in my memoir.
During the long summers with my dad, I often hung out at his laboratory. One summer I helped him build this giant plankton net that he used to sample animals in the Gulf of Mexico.
My dog, Puppy, helped get me through the difficulty of my parents’ divorce, so Puppy became a primary character in my book. Man, I wish I still had that shirt!

'Tis the season. The rotting season.
You thought Halloween was full of ghosts, goblins and ghouls? Well, wait until the post-Halloween season. This is when your Jack O' Lantern begins its ghoulish decline. It starts as a pumpkin and it ends as a heap of goo. This is scary!
Now is when your Halloween pumpkin begins to rot. Don't get me wrong. Rot is not gross. It is a beautiful thing—beautiful in its own deliciously disgusting way.
You start with a proud Jack, a plump, shiny-skinned pumpkin. Halloween is over so you leave it on your porch, or inside by the window, or maybe you toss it into the garden or onto the compost heap.
It attracts some visitors. A squirrel. A pair of mice. A scurry of sow bugs. They chew the skin of the pumpkin, leaving moist, rough surfaces, just perfect for the next wave of invaders: the molds and fungi and bacteria that start to grow. There are dozens, even hundreds, of types of organisms waiting to sink their "teeth" into pumpkin flesh as soon as the conditions are right. One kind of invader changes the conditions of the flesh to make it perfect for the next one. Meanwhile, the poor pumpkin is looking less and less like a pumpkin. Its skin turns to shades of black, gray and white, with only a few patches of dull orange. Its shape collapses into a heap, then a pile of mush, and then . . . well, no shape at all.
Do you think rot rots? Imagine what your life would be like if things didn't rot. You'd be tripping over all the old pumpkins, not to mention mice, eagles, tomato plants, oak trees and everything else that ever walked, flew, swam or grew upon the earth. Their dead bodies simply wouldn't go away! Worse, their nutrients would be locked forever inside. The energy in the molecules they are made of would be unavailable to any other living things. Rot, properly known as "decomposition," releases all those good vitamins, sugars, proteins, carbohydrates and energy so that they can be used by next year's pumpkin, which will grow from the seeds of last year's pumpkin. Mice and eagles, tomatoes and the trees in a nearby forest can grow and reproduce because nutrients and energy pass through complex food webs from plants to the animals that eat those plants, to other animals that eat those animals.
It's all possible because of rot. So you see, rot doesn't rot. Rot rocks!

You know how it is: old campfire stories, interesting things you’re doing or seeing or hearing about—they get all mixed up in your dreams and your stories. That’s how it was for Mary Wollstonecraft Godwin. One night in 1816, in Switzerland, when there wasn’t anything on TV (because it wasn’t invented yet), she and her friends decided they’d each write a horror story. By combining her knowledge with the idea what if, 18-year-old Mary made up one about a monster. It’d turn out to be one of the most famous monsters ever.
These were some of the ideas that influenced Mary’s thinking:
Hmmm…I’ll bet you can guess now what story Mary wrote! In it, her character, Dr. Victor Frankenstein, gathered parts of dead people’s bodies in his laboratory. His experiment? He’d make a perfect person then bring it to LIFE with the power of lightning – and it worked! But – oh no! Dr. Frankenstein accidentally created a MONSTER! And then a lot of horrible things happened!
Mary Shelley’s Frankenstein, which was first published in 1818, never got very good reviews, but never mind. In the almost two centuries since she wrote it, Mary’s monster story has sparked the imaginations of playwrights, moviemakers, cartoonists, musicians, and Halloween costume-makers again and again and again.
It kind of makes you wonder about your own ideas and memories. What if you put them together in your imagination? You could spark a story into LIFE!
