A Tardigrade Christmas…

 …A Different Christmas Story… (with a nod to Lewis Carroll)

Blika lived in Mossland with her clone sestras, gathering and sucking the delicious juices of detritus and algae. Never in a hurry, she lumbered from frond to frond on eight stubby legs in a gestalt of feasting and being. Blika led a microscopic life of bloated bliss—unaware of forests, human beings, quantum physics or the coming singularity…

A sudden fierce wind wicked her water away. In a burst of alien urgency, she wriggled madly for purchase on the frond as it shivered violently in the roaring wind. Blika lost hold and the wind swept her into a dark dryness. Her liquid life-force bleeding away from her, Blika crawled into herself. The moss piglet felt herself shrivel into oblivion.

No, not oblivion… more like a vast expanse…

She had entered a wonderland of twinkling lights in a vast fabric of dark matter. Where am I?

“Welcome, sestra!” boomed a large voice.

It occurred to her that she had never thought such a thing before. Am I dead? She’d never thought about existence before either. What has happened to me? And where are my sestras? She felt an overwhelming sadness. Something else she’d never felt before and wondered why she hadn’t. Did it have to do with that liquid that had always embraced her with its life-force? Here, in the darkness of space, she felt alone for the first time, separated from the plenum.

Blika beheld a being like her with eight arms and hands, seated on a throne and wearing a jeweled crown. “Why do you call me sestra?” Blika asked.

“Because we are ALL sestras! You are a Tardigrade, aren’t you?” She waved all eight arms at Blika. “Well, I am your queen!” She looked self-pleased. “You are in Tunland now! The land of awareness. And now that you are self-aware, you can do anything! We’re special,” the queen ended in smug delight. The folds of her body jiggled and shimmered.

“Why are we special?” Blika asked.

“Because we are!” the queen said sharply, already losing patience with her new subject. “Don’t you know that you can survive anything? Ionizing radiation. Huge pressure. Boiling heat. Freezing cold. Absolutely no air. And no water…”

Blika gasped. Water was the elixor that connected her to her sestras and her world… her…home…

“How do you think you got here, eh?” the queen mocked her with a sinister laugh. Blika cringed. The queen went on blithely, “So, where do you come from, piglet?”

“I’m trying to find my way home…”

“Your way? All ways here are my ways!”

“But I was just thinking—”

“I warn you, child…” The queen glowered at her. “If I lose my temper, you lose your head. Understand?”

Blika nodded, now missing her home even more.

“Why think when you can do!” the queen added, suddenly cheerful again. “First there is BE, then THINK, then DO. Why not skip the think part and go straight to the do part? In Tunland we do that all the time,” she went on blithely. “And, as I was saying, here we can do anything!”

The queen grabbed Blika by an arm and steered them through the swirling darkness of space toward a box-like floating object. “This is my doctor’s Tardis…”

“Doctor who?” Blika naively asked.

The queen shivered off her annoyance and led them eagerly through the door and into her kingdom.

They entered a strange place of giant blocks and whining sounds beneath a dark swirling sky.

The first thing Blika noticed was the huge tardigrades floating above them like dirigibles! Others were dressed in suits holding little suitcases and walking into and out of the huge blocks through doorways.

“We’ve crossed into another dimension—my universe,” the queen announced cheerfully. “Here you can do anything you want. So, why be tiny and feckless when you can be huge and powerful!” She studied Blika. “This is your moment to do what you could never do before. Think of the possibilities! You too could be huge!”

Blika stared at the strange world of smoke and metal and yearned for her simple mossy home.

As if she knew what Blika wanted, the queen quickly added, “But you can never go back home!”

“Why not?” Blika asked, disappointed.

Because, that’s why!” the queen shouted.  Squinting, she added, “It’s too late. It’s just not done! Once you’ve learned what the colour green means you can’t erase its significance!”

“But I still don’t know what the colour green means,” Blika complained. “And, besides, I think you’re wrong. Becoming self-aware doesn’t stop you from going home. It just changes its meaning. And if I can really do what I want, then you can’t stop me. I’m going home to my family.”

The little hairs on the queen bristled. Then she grew terribly calm. “I won’t stop you, but…” The queen pointed to the floating tardigrades above them. “My water bear army will. I sentence you to remain in Tunland forever for your crime!”

“I haven’t done anything…yet.”

“You’ve broken the law of thinking before doing. In Tunland you have to skip that part—”

“You just made that up—”

“Doesn’t matter!” shouted the queen. “Sentence first, verdict afterwards!”

“That’s nonsense,” said Blika loudly. “The idea of having the sentence first.”

“Hold your tongue!” said the queen, turning a shade of chartreuse.

“I won’t,” said Blika.

“Off with your head!” the queen shouted at the top of her voice, pointing to Blika with all eight of her appendages. The water bear army hovered over Blika, taking aim. They were going to get more than her head with those lasers, Blika thought, and scurried for cover faster than her stubby eight legs had ever moved before. She was doomed—

Then, just beyond her sight, she saw—no felt—something far more significant than the colour green…or a huge bloated water bear army about to shoot her…

Water! She could taste it, smell it, hear it. Blika rejoiced with thoughts of her green home.

The water came in a giant wet wave of blue and silver and frothy green. Tunland sloshed then totally dissolved. Blika surfed the churning water. That green! She knew what it was! Blika reached out with her deft claws and snagged a tumbling moss frond. It finally settled and there were her sestras! So many of them clinging to the same green moss! She’d found her family! She was home! Yes, it was a different home and different sestras, but it was also the same. Love made it so…

Merry Christmas!

Tardigrade ornament (Archie McPhee)

water bear02 copy

Tardigrades, also known as water bears or moss piglets, are plump, microscopic organisms with eight clawed legs. Fossils of tardigrades date to the Cambrian period over 500 million years ago. Over 900 species are known. Tardigrades were first described by the German pastor Johann August Ephraim Goeze in 1773 and given the name Tardigrada, meaning “slow stepper,” by the Italian biologist Lazzaro Spallanzani. Tardigrades reproduce asexually (parthenogenesis) or sexually. They mostly suck on the fluids of plant cells, animal cells, and bacteria.

Tardigrades survive adverse environmental stresses including:

  • High and low temperatures (e.g., -273°C to +151°C)
  • freezing and thawing
  • changes in salinity
  • lack of oxygen
  • lack of water
  • levels of X-ray radiation 1000x the lethal human dose
  • some toxic chemicals
  • boiling alcohol
  • low pressure of a vacuum
  • high pressure (up to 6x the pressure of the deepest ocean).
Water Bear or Tardigrade

Tardigrades respond to adverse environmental stresses through “cryptobiosis”, a process that greatly slows their metabolism. Tardigrades survive dry periods by shriveling up into a little ball or tunand waiting it out. They make a protective sugar called trehalose, which moves into the cells to replace the lost water. You could say that the water bear turns into a gummy bear.

Tardigrades have revived after a 100 years of desiccation. The antioxidants they make soak up dangerous chemicals and tardigrades can also repair damaged DNA from long term dry-out. In low oxygen, the tardigrade stretches out, relaxed muscles letting more water and oxygen enter its cells. The tardigrade’s cold-resistant tun also prevents ice crystals that could damage cell membranes.

Tardigrades survive temperatures, pressures and ionizing radiation not normally found on Earth. All this raises questions of origin and evolutionary adaptation. How—and why—have tardigrades developed the ability to survive the vacuum and ionizing radiation of space? Some suggest that it’s because they originated there. Scientists argue that they developed extreme tolerances from Earth’s volatile environments (e.g., water bodies that freeze or dry up, and undergo anoxia). But, if they can make it there, they can make it anywhere. So, where is “home” really?…

Nina Talks Water with Grade 8 Students on World Water Day

Nina-Grade 8 on Water-March22-2018 copy

Nina talks with Valleys Senior Public School Grade 8 students about water

On World Water Day, at the kind invitation of Alene Sen (supervisor and coordinator for the City of Mississauga at the Mississauga Valley Library) I talked to some 100 Grade 8 students of Valleys Senior Public School about water. Several classes, in groups of about fifty students each, came at tandem to the library to learn something about water.

I had about half an hour to prime them with something that would spark their interest and which they could take home and think about—and possibly apply in stewardship.

carboniferous-paleozoic eraI started the talk by explaining that I’m a limnologist—someone who studies freshwater—and that water is still a mysterious substance, even for those who make it their profession to study.  After informing them of water’s ubiquity in the universe—it’s virtually everywhere from quasars to planets in our solar system—I reminded them that the water that dinosaurs drank during the Paleozoic Era is the same water that you and I are drinking.

We briefly reviewed some of water’s most interesting anomalous and life-giving properties such as cohesion and adhesion—responsible for surface tension and water’s capillary movement up trees. Below is an excellent 4-minute YouTube video “The Properties of Water” that describes these properties well.

I reviewed the circle of life and energy in an aquatic ecosystem and used the grey whale as an example to study trophic cascades and the balanced trophic cycle—with an endnote on the whale’s significant role in influencing climate.

I introduced each class to the incredible and very tiny Tardigrade, also known as the water bear or moss piglet, with magical properties of its own. The 4-minute TED video by Thomas Boothby is particularly instructive and entertaining.

I then showed the class an image of the Three Gorges Dam in China and reported how as a result of so much dam-building and retention of water—and because most dams are located in the northern hemisphere—we have slightly changed how the Earth spins on its axis. We’ve sped its rotation and shortened the day by 8 millionths of a second in the last forty years.

3-gorges dam

Water needs to constantly move. The Water cycle moves through the planet in all three forms (vapour, liquid and ice), over land and sea and through the earth, but also through all life. We are part of that cycle. We drink it and get immersed in it; we also breathe water in with every breath we take and breathe it out with every breath we exhale.

We are water; what we do to water, we do to ourselves.

I invited the class to discuss things we could do to help water as it moves through the planet. We talked about things we could do at home, with our friends, in our school and community to help water. Things like planting a tree in your back yard; adopting a nearby stream and taking care of it; organizing a beach clean-up; deciding to do something at home to waste water less.

Each action is a small thing. But that is how large things happen, through the accumulation of small things. And with every “small” action is a small shift in thinking, which leads to the kind of leadership that will change the world and make it a better place—for water and everything that depends on it.

After a discussion of the problems now facing water on the planet, we asked the students from The Valleys Senior Public School to answer the question “What can we do to help water?” on a small sheet of paper, which we then collected. Their responses showed great thought and a willingness to do something concrete. Alene created a billboard at the Mississauga Valley Library with the Valleys Senior Public School student responses to the question.
