We’re Not Alone

The Secret, Trillion Lives
Crawling In & On Your Body

The late Carl Sagan may have said, we’re all made of starstuff. But deep down, what we really are is a multitude of microorganisms, 100 trillion of them, some part of our natural physiology, but most totally foreign. We wouldn’t have lasted this long on Earth without them.
While cells are the bricks that form our bodies, even before birth, an ever growing, self-renewing, array of microscopic creatures call us their home and, gasp, may also call the shots about everything we think we are, from how healthy or moody, to when we’ll finally expire.
So much for freewill. This invisible trillionaire community, living off our so well washed and fed bodies, shelters charitable organisms which allow us to survive what would’ve killed us in the past, and downright lethal pathogens for which there’s no defense. And yet others are content to just control whoever we follow on Twitter.
To learn about these entities, simple but formidable enough to erase a city’s population, is to find multiple new questions to every doubt we may clarify. It’s also to wonder how come a brainless, single-cell being can play such a complex role in the evolutionary ladder.
Notice that we hadn’t mentioned viruses till now; we figure too few would that eager to hear about them once more. But if bacteria can be foreign to us, viruses are totally aliens as they have no cell or internal structure. All killing’s done with the thinnest protein layer and a string of nucleic acid. We’d let those dogs lie for now, if we could.
Bacteria, however, can actually be our allies, and our guts hold enough of them to actually defeat an alien invasion, as H.G. Wells‘ illustrated so well in War of the Worlds. Not for long, though, as we overuse antibiotics, which kill both good and bad ones, and give rise to a new breed of superbugs. Watch out.

MAFIA BUGS & ZOMBIE SPIDERS
Speaking of evolution, a step above, more complex and considerably larger, are parasites, which are tiny insects, still invisible to our poor eye sights, but very capable all the same. Nature is full of them, and now we’re also learning that some can be pretty clever, controlling bigger creatures. Including us.
There’s one, for instance, that once inside a bumblebee, can force it to become food for its larvae, not before digging its own grave, though. They called it a Mafia Bug, but you haven’t heard it from us. Curiously, such approach to domination is emulated by other, larger creatures, such as some kind of wasps.
The Pompiliadae, a.k.a. Spider Wasp, is so called for a reason: it poisons and paralyzes without killing a spider, drags it to its burrow, bury it, and lay eggs on top of it, so it will be eaten still alive by its larvae. Pretty horrific. Another wasp does something similar: it turns the spider into a zombie construction worker.
Well, you may say, at least it teaches it a marketable skill. Except that it also paralyzes the spider and lays its eggs, etc. Not a fate one would think dignified enough for anyone, but, gasp again, it may be already happening. And your favorite pet may have something to do with some of your dark thoughts.

IT COMES FROM INSIDE YOUR CAT
Research is not new, but it goes along with the same M.O. displayed by the parasites we’ve mentioned, except that this time, the joke, er, the zombies may be us. The Toxoplasma gondii infects domestic cats via their food, and can manipulate certain cells to gain access to the central nervous system of a human.
Since the protozoan can live in many environments but survives only in the guts of cats, evolution may have given it a surprising edge. It’s been proven, for instance, that once it’s present (more)

Beneath the Waves

High Noon at Big Blue: Menopausal
Whales & Jellyfish-Murdering Robots

They stand far apart in the immense liquid yonder enveloping the planet. One massive and rare, the other transparent and quasi immaterial. Whales and jellyfish have been around for millions of years, but as one’s likely to outlive us, we miss the other already.
They’re both beautiful, no mistake about it. But while the Medusa and the Man of War are growing strong around the oceans, the majestic blue and the singing humpback, harmless as they are, are swimming to oblivion, and may not get to meet your great-grandchildren.

It doesn’t help that we know so little of either one, and that the very world they inhabit, from which we all draw our sustenance, is on the verge of collapse, victimized by pollution, climate change and overfishing. While we multiply, marine life dwindles, and it’s the fragile among us that’s going first.
For when it comes to survival, size may be a liability. Ours is in the numbers; the whales’ is in the scope of their physicality. Aliens on earth and sea stand a better chance: viruses, bacteria, bugs and jellyfish have proven way more adaptable to beat even a formidable foe as all species have found in us.
The ocean is in fact so broken that a new study found out that an annual ‘dead zone’ in the Gulf of Mexico, which last year was the size of New Jersey, will continue for several decades.
These areas, which occur when there isn’t enough oxygen in the water to support marine life, are spreading out throughout the oceans and their cause is attributed to nutrient runoff, from agricultural fields which are heavily fertilized during spring.
As these areas grow, marine life recedes, and the natural diversity of the seas becomes severely depleted, even if eventually reasonable levels of oxygen return. Like a change of guard from hell, living creatures, turtles, dolphins, sharks, whales, and their accompanying flurries of feeding birds, are being quickly replaced by plastic, garbage, synthetic rope, and polystyrene foam: the new fruits of the sea.

BLOOD IN A SMALL POND
Blackfish is a documentary about the late Tilikum, an orca whale who spent her 25-plus years in captivity at SeaWorld, which ‘accused’ her of having killed or being involved in the deaths of three of its trainers. The documentary, which in the U.S. became a public television hit, was an indictment on the brutal conditions such wondrous animals are kept in this class of for-profit enterprises.
Forced to a gruesome routine of non-stop training and performing, the 12,000 pound bull, who lived most of her life in a tank the size of bus, had the typical signs of physical and mental deterioration that plague captive animals. The documentary fought SeaWorld to free Tilikum, but she died last year without ever returning to the open sea.
A powerful reason that should’ve ended enslaving whales as toys is the fact that they do share common traits with much smaller-brained humans. They live in highly complex societies, and now researchers found that they also can reach menopause, just like grandma, as one of the few species that live longer than their reproductive years.
A team at the universities of Exeter and of York is undertaking a long-term study to find out exactly how orcas organize themselves (more)
