Colonies of Mycobacterium (a genus of Actinobacteria) have a characteristically waxy consistency. Shown here: colonies of M. tuberculosis.
THE MOST DEADLY PATHOGEN OF ALL TIMEPosted April 12, 2014 by Kas Thomas at assertTrue( )

Few bacterial species have had as great an impact on humankind as the members of the [Mycobacteriaceae] family, which encompass the causative agents of (among other ailments) leprosy, tuberculosis, and Crohn’s Disease in humans, and Johne’s Disease in farm animals.
Leprosy is known from antiquity and continues to strike 200,000 or more people each year worldwide.
Tuberculosis, which affects (subclinically) one in three persons worldwide, continues to kill well over a million people a year and has caused a billion deaths in the last two centuries, more than all the wars and genocides of history combined.
The association of M. avium subspecies paratuberculosis (MAP) with Crohn’s Disease is still considered controversial by some, but if in fact Koch’s criteria have already been met, MAP adds millions more to the toll of human misery caused by Mycobacterial infection.
What are these bacteria? Where did they come from? How have they managed to be so successful in causing death and disease?

The Winter Soldier wears a mask for most of the film, which made it difficult for me to convey emotions. But it also kind of helped in a way. I felt when I was looking at myself in the mirror that I couldn’t recognize myself at all.

Fairy rings occupy a prominent place in European folklore as the location of gateways into elfin kingdoms, or places where elves gather and dance. According to the folklore, a fairy ring appears when a fairy, pixie, or elf appears. It will disappear without trace in less than five days, but if an observer waits for the elf to return to the ring, he or she may be able to capture it. They are soooooo beautiful!

fairy rings are usually caused by decaying organic matter, generally a tree stump. many types of fungi have symbiotic relationships with tree roots and mushrooms are the fruiting bodies of such fungus. So if a huge old tree was cut down, you’ll often find fairy rings. they can last for years and years as the earth  reabsorbs all the nutrients left behind by the beautiful tree.

sorry, didn’t mean to crush dreams - but i have a degree in horticulture and i was really excited when i first learned this.

maybe fairies and fungi are joining together to mourn the loss of the tree

xo

NO BUT FINDING OUT ABOUT WHY FAIRY RINGS EXIST IS ALSO REALLY COOL.

From a writer’s perspective, it’s even more interesting to find out why they exist on a horticultural level, because it opens up a whole realm of fictional possibilities. Science doesn’t have to invalidate mythology or fiction, no more than mythology or fiction invalidates science.

For example, doesn’t that just essentially make this a tree grave? And if folklore has taught us anything, it’s that “fairies” and other spirits usually occupy trees, or have them as their life force. And that’s to say nothing of the folklore of trees being spirits in and of themselves, or kitsunes that live in tree hollows, or dryads, etc., etc.. So, if it’s disrespectful or feels like a slight to step on human graves, wouldn’t that logic transfer to stepping inside the Fairy Circle, AKA, the tree’s grave? It’s essentially giving more fuel to the story, not detracting from it, in my humble opinion!

Science doesn’t have to invalidate mythology or fiction, no more than mythology or fiction invalidates science.

What men don’t understand is that women are FIERCELY PROTECTIVE of underage girls because we remember when we were young and some adult man made us uncomfortable or manipulated us or was inappropriate with us and we were powerless.
