Mushroom-Robot Biohybrids

Robots controlled by electrical impulses from fungal mycelium threads:

Robot Blends Living Organisms and Machines

The "rootlike threads" are grown into a robot's hardware. I was surprised to learn fungi generate electrical impulses. Because the mycelia are light-sensitive, scientists can control the direction and speed of the robots' movements with ultraviolet light.

It's hoped that, when perfected, such biohybrid machines could have agricultural uses, among other applications. The article includes a photo of a robot covered with a "self-healing skin. . . that can react to light and touch." The picture looks a bit like the conventional image of a golem.

I'm reminded of T. Kingfisher's riveting novel WHAT MOVES THE DEAD, a retelling of Poe's "Fall of the House of Usher" in science-fiction terms. It attributes the eerie phenomena -- e.g., the climactic rising of a dead character from her tomb -- to an intelligent fungal colony that lives in the tarn and infiltrates the bodies of animals (and at least one person). The organism seems to be trying to communicate and apparently doesn't mean any real harm. How could it understand why humans get upset when corpses walk around?

Has anyone ever produced a horror movie about a swarm of intelligent fungi? If mushroom-robot symbiosis ever results in a successful commercial product, surely such a film couldn't be far behind.

One expert in the ethical implications of technological innovations expresses concern "that if biohybrid robots become more sophisticated and are deployed in the ocean or another ecosystem it could disrupt the habitat, challenging the traditional distinction between life and machine." However, there's no mention of a potential for mycelium-powered machines to become conscious and demand civil rights or fair salaries, fringe benefits, and working conditions.

Microbiome Universe

Here's another article about the microscopic ecology inside our bodies:

Microbes Rule Your Health

The microbes that use us as a habitat outnumber our own cells by 1.3 to one. Many of them dwell in symbiosis with us and serve beneficial functions. Living in a state of complete sterility would not be good for most people. Jack Gilbert and Rob Knight, authors of DIRT IS GOOD, referenced in the article, explain why exposure to germs and other "impurities" in the environment strengthens our immune systems. Not only that, "Microbes in the gut talk to the brain." So it's to our advantage to encourage our "good" internal tenants to thrive and multiply, and the article mentions several ways to accomplish that goal.

This topic reminds me of Madeleine L'Engle's novel A WIND IN THE DOOR, in which Meg and her companions become submicroscopic to enter the body of her critically ill brother, Charles Wallace. There they meet the farandolae, sapient creatures dwelling in the mitochondria of Charles's cells, to whom his body is a galaxy. Meg and these infinitesimal beings, whom she helps to heal, awaken to the interdependence of all things in the universe, from minute farandolae to distant stars.

Considering our microbial inhabitants along with other creatures we harbor, such as eyelash mites (I know, squick), an alien observer might think our main purpose for existence is to provide a home for trillions of smaller life forms. If our tiny tenants had intelligence and could communicate with us, what wisdom might they impart?

Microbiome Evolution

Recent research about the human microbiome—the ecology of the microorganisms that live in our bodies—indicates that the many species of flora and fauna inhabiting our digestive tracts originated with our prehuman ancestors and evolved in parallel with them:

Primates and Gut Microbes

A genomics researcher in Bethesda, Maryland, suggests that "this mutualistic symbiosis helped the human species evolve." We inherit not only our genes but our internal symbionts.

Another article I read about this discovery mentions that the cumulative mass of microbes in our intestinal tract typically outweighs our brain. It's boggling and humbling to contemplate how much of what we call our own body consists of alien organisms, most of them friendly or harmless.

This topic reminds me of Madeleine L'Engle's A WIND IN THE DOOR (sequel to her classic A WRINKLE IN TIME). Young heroine Meg becomes miniaturized in order to travel inside the body of her gravely ill little brother, Charles Wallace. She meets submicroscopic creatures who live in Charles Wallace's mitochondria. To these beings, a cell is their entire world, and Charles's body is a galaxy. They don't even realize their "galaxy" is sentient until Meg enlightens them. They and she become aware of the vital interconnectedness and inestimable value of all parts of creation, no matter how tiny or vast.
