This was posted two years ago. I liked it then, and I still do.

It's  late June.

Light life and more light and more life. Little makes sense, but in June the abundance pushes aside the questions.

I have tooth marks in my thumb from a fluke. A snake no longer than a ruler tried to strike me a few hours later. A lone bat heralded dusk.

School winds down in June.

Next year I plan to start with Darwin's idea of descent with modification. He did not invent evolution. He did, however, figure out that the raw beauty of life's symphony here can be explained without appealing to some central plan that places humans above all else.

It's all there for those who care to look.

If you are going to acknowledge something is unknowable or incomprehensible or too powerful to comprehend, hey, I'm right there with you. Many things will remain unknowable in any scientific sense.

When you try to explain the inexplicable, when you presume to know the "meaning" of existence, though, keep it outside my classroom door. I teach biology, not metaphysics.

I'll be glad to discuss the "unknowable" with you,
ideally by a lake at dusk,
watching bluegill sucking down lightning bugs
enamored by their own reflection.

Just not in class.

Mid-June.

The blueberries are still mostly green, just blue enough to remind me of Uranus through our scope.

Raspberries and snow peas and basil and purple beans explode in our mouths, in our brains.

Light, light, and more light floods us daily--anything is possible in June, anything. There's enough energy for all of us who survived the past winter, more than enough.

"Enough" is a wonderful word foreign to many of us. If you know "enough," you know "content."

Less than a week ago, a dolphin eyed me, and I eyed it back. Not much to say, even if we could speak the same language. It's June, and there's more than enough to go around.

I am reading Science for All Americans, the AAAS book describing Project 2061. The second paragraph starts with this:

Education has no higher purpose than preparing people to lead personally fulfilling and responsible lives. For its part, science education...should help students to develop the understandings and habits of mind they need to become compassionate human beings able to think.

Amen.

Are you listening, Arne? Bill? Eli?

In June, the words of the powerful sound silly--but come November, when darkness falls and fear, again, prevails, Arne will cast his spell again.

Without fear, Arne loses his grip. Without fear, we can teach again. Without fear, we can resume this great experiment.

Puny men can only rule through fear. I'm done worrying. I'm going to teach science.

How about you?

The key to all this is recognizing our own mortality.
Get that down, and Arne's just another semi-pro basketball player with connections.

Why "Johnny Appleseed"? It's June...why not?

And no, Chris Cerf did not invite me back.

I run this every June, because I like lightning bugs.

First lightning bug tonight. I never tire of lightning bugs.

I

Dusk settled on the lake. I could hear the kiss of bluegills as they sucked down insects struggling on the surface.

A few lightning bugs flashed above the mirrored surface. Attracted by their own reflections, they swooped ever closer to the lightning bugs flashing below them.

Fish may not be smart, but they're not all get-out stupid, either. And a bluegill will jump if hungry enough. A few were hungry enough. Inside their bellies glowed a few foolish lightning bugs.

Lightning bug light is cool-literally. Luciferin combines with ATP, the energy molecule of life--the resulting compound combines with oxygen, catalyzed by luciferase, and light results. Even tiny amounts of ATP will cause luciferin to light, as long as oxygen is present. While man has never been to Mars, bits of lightning bugs have--luciferin is an extremely sensitive detector of ATP. If it flashes, carbon-based life may be present.

Luciferase from the North American firefly (Photinus pyralis) is the enzyme of choice for reporter gene assays. Luciferase catalyzes the oxidation of a firefly-specific substrate called luciferin to produce light. This reaction is extremely efficient and the quantum yield is the highest of any characterized bioluminescent reaction. The bright signal makes this a valuable enzyme to use for reporting promotor activity. • Packard’s LucLite® assay system, introduced in 1994, produces a long lived glow type signal with a [half-life] of several hours, which makes it ideal for use in noninjector based HTS luminometers, like the Packard TopCount® NXT Microplate Scintillation and Luminescence Counter or the Packard LumiCount® Microplate Luminometer.

Scientist have yet to synthesize luciferin, so they buy lightning bugs.

My daughter dug out a tiny mudhole for me in our backyard. At dusk, I sit opposite the pokeweed I am learning to like, under a stray white birch I have always liked. Lightning bugs arise from the earth, flashing their "J"'s, looking for love. Harry Potter, like the Bible, makes sense sitting outside on an early June evening.

I read until the dusk chases words off the page, my feet resting on a small stone wall we built together.

A flash just below my right foot.

I break from Harry Potter. A second scurrying critter rumbles about the flash. The flashing becomes frantic, several short blips in less than a few seconds. My eyes adjust--a spider dances around its prey.

I've never seen a lightning bug flash quickly like that, but then I've never seen one eaten by a spider either. A lightning bug makes a flash by adding a tiny bit of ATP to luceferin. In our mechanistic view of the world, not a bad worldview if you're in the business of conquering it, lightning bugs flash instinctively. They are not known to flash for defensive purposes.

I cannot know why this one flashed, but I do know that lightning bugs, at least this one, had a pattern distinct from its cherchez la femme mode when struggling with a spider.

I almost didn't try to "save" it--a good naturalist observes, does not interfere. The spider has as much a right to the meal as I do to mine. Death by spider is likely to be quicker than death by starvation if the critter could no longer fly.

I pulled the frenetically flashing bug out of the web--a white wisp of web stuck to its backside. I set it on a leaf of the birch with mixed feelings. It will die slowly because my imagination would not allow me to let the spider bite it.

As the critter struggled with its first pair of legs to grasp the edge of the leaf, I gently pulled back the stick. The spider silk stuck to my stick. The lightning bug scootched a few millimeters, no longer flashing, and stood still.

I watched a moment longer. The lightning bug opened up its beetley shell, opened its wings, and flew away.

A moment later, a lightning bug brushed my leg at the bottom of its "J". No way to know if it was the same one. And it really doesn't matter.

Some Asian lightning bugs flash in unison. The lightning bugs in the Jersey area, at least the ones that make a J, are not known to do this (according to the scientists). Oh, occasionally they'll accidentally flash together a few seconds after the flash of a bright light, as though they were all resetting their bellies after seeing a god, but left alone, our fireflies are supposed to be the individualistic sorts.

The local critters must be illiterate--once or twice a dusk, they amuse themselves with synchronous flashing. (“Amuse” sounds like anthropomorphizing, of course--it’s an interesting word, comes from the French amuser, “to stupefy”--we’re most amused when our brains are buggy.) .


V
One poor fellow one evening couldn’t turn off his belly --he’d glow properly enough in his “J”, but still fizzled a bit as he looked for a response--doubt he could see much light beyond his perpetually lit self.

I muttered “padiddle.” .


VI
Lightning bugs are, obviously alive. They have a lot of ATP. They have a lot of luciferin and luciferase. We made lightning bug earrings, lightning bug drawings, we’d smear dying and dead lightning bugs over our faces and laugh and scream like the atavistic creatures we were, mock Indian face paint.

I am a science teacher; I am not a scientist. A lot of folks are confused about what constitutes science. We want children to be amazed. You can purchase, via PayPal, a lightning bug “collection system.” You have a choice of sizes, and the handle glows in the dark. Imagine that! No doubt safer than punching holes in a half-rinsed mayonnaise jar.

Kids can study and be fascinated by all the little bugs found in the average back yard. Firefly lanterns allow children to watch the lighnting sicbugs light up. The bugs can be returned to nature where they were found after a day or two of enjoyment.

Another “experiment” suggests that kids catch lightning bugs in a jar for 5 minutes, record their observations, then let them go.

Took me 40 years to realize I learn a whole lot more doing nothing, feet up on a tiny stone wall next to my daughter’s puddle.
