End of Life Care Machine

Designer, artist and engineer Dan Chen has developed the ‘End of Life Care Machine‘, a machine designed to guide and comfort dying patients with a carefully scripted message. Chen, just graduated from the Rhode Island School of Design, built the machine as one of a series of functional robots capable of reenacting human social behaviors.

The patient enters the specially designed room and lays on the bed. The doctor asks for permission to put the patient’s arm underneath the caressing mechanism.

“The device is activated, and an LED screen reads “Detecting end of life.” At this point, the doctor exits the room, leaving the patient alone by him or herself. Within moments the LED reads “End of life detected”, the robotic arm begins its caressing action, moving back and forth, stimulating the sense of comfort during the dying process.”

The machine then plays the scripted message:

Thirsty? With a Cyborg Bladder, You’ll Never Need to Drink

Some desert animals, like the kangaroo rat, get through their lives without needing to drink even a drop of water. Now, a Japanese design company aims to make humans just as efficient. Faced with a fictional, future scenario of global apocalypse, Takram was tasked with the challenge of creating a water bottle for the end-times. The designers quickly realized that the best approach was not a bottle at all, but a set of artificial organs that retain and recycle the water already present in the body. Their Hydrolemic System is the cyborg’s answer to surviving global warming, nuclear explosions and Death Valley.

Humans are leaky. We sweat, pee, and breathe out all our hard-earned water. The Hydrolemic System uses several devices to minimize this loss. Two nasal inserts harvest exhaled moisture. A generator implanted in the jugular, in combination with a neck collar, transforms body heat into electricity and reduces the need for sweating. Even better are the urine concentrator and the rectal fecal dehydrator, both intended to make every bathroom trip a dry-as-dust affair. The system works in concert with “rubedo candies”, small pills that contain a day’s nutrients and 32 mL of water – less than a thimble-full.

Get into Buckminster Fuller

You have a choice dear reader: spend 4 seconds scanning this blogpost, or spend the full 58:10 minutes (*) watching the retro-futuristic interview with polymath & nextnature thinker avant la lettre Buckminister Fuller.

(*) We are well aware these are times of short-attention span, yet sometimes you have to immerse yourself. We actually recommend watching the video twice to obtain an optimal understanding and appreciation of the material.

Synapse Structure

Replacing Synapses with a Single Switch

Neural synapses in the human brain are extraordinarily complex structures. Responsible for relaying information between neurons, chemical synapses govern the release of over 100 different kinds of neurotransmitters, while electrical synapses deliver information via electricity for rapid-fire reflexes.

Now, researchers in Japan have invented a simplified synapse in the form of a “solid-state electrochemical nanodevice” that functions as a switch. The gap between these two synthetic synapses is bridged by a tiny copper wire, which changes in conductivity over time. Though at first it may seem a bit esoteric, this new device actually mimics what goes on in the construction of sensory memory, short-term memory, and long-term memory. The scientists behind this synapse are hopeful that it will lead to more life-like artificial minds, as well as treatments for the human brain.

It’s interesting that this nanodevice may in some ways have improved upon a biological synapse. Evolution tends to lead to local maxima – it reaches the best design given existing structures, but it can’t invent entirely new solutions out of nothing. The “blind spot” is a classic example: Because the optic nerve connects through the retina, there is a blank region in our field of vision where the nerve cells have crowded out the sensory cells. The brain has evolved very clever ways to deal with this deficit, but evolution hasn’t actually been able to completely solve the problem.* Maybe science may soon find more “intelligent designs” that cut some of the evolutionary clutter. As always, we welcome our hyper-efficient cyborg overlords.

Bacteria Inspire Magnetic Hard Drive

Certain types of bacteria can navigate using magnetic nanoparticles as tiny compasses. Researchers at the University of Leeds have extracted the protein that controls this process and applied it to computing. Typical hard drives use use “granular computing”, while this new method relies on bit-pattern media, where each miniscule magnetic square on a surface can store one bit.

The team is close to recreating the data density of modern hard drives, and hope eventually to be able to store one terabyte of date per square inch – more advanced than any existing hard drive. According to Sarah Stanilan, who lead the research, “We’re using and abusing nature because it’s had billions of years to do all of its experiments through evolution, so there is almost no point in us starting from scratch.”

Regrowing Bones with Silk

Time to add another superpower to insect silk, which already includes bulletproof skin and implantable microelectronicsRecent research indicates that silk may be an ideal candidate for creating strong, flexible scaffolding for re-growing bones. Scientists used a chemical process to break silk strands down into nano-scale fibers that were used to reinforce a silk protein scaffold. By mimicking the natural roughness and stiffness of bone, this biodegradable structure helps to encourage vigorous bone growth. While certain biomaterials are at the center of research into bone regeneration, few of these existing materials can match silk’s toughness, especially in load-bearing grafts.

The Ecological Human

The nature of humanity in the twenty-first century is, according to sociologist Steve Fuller, a ‘bipolar disorder’ beset with dualisms of identification such as divine/animal, mind/body, nature/artifice and individual/social. He notes that they have challenged our collective sense of identity as ‘human’, particularly though the operationalization of the mind/body question in new material configurations of metallic or silicon bodies [1].

In short, we are ‘becoming’ machines. Inventor Ray Kurtzweil and performance artist Marcel Li Antunez Roca both explore this notion in their projections about the future of the human body. Yet ‘emergentist’ philosophers and scientists have challenged the mechanistic model of matter since the late 18th and early 19th century. They propose another way of understanding the organization of matter [2], without resorting to the customary mechanist  [3] – vitalist [4] dichotomy [5]. Observations from the biological and chemical sciences demonstrate that substances frequently do not behave in a manner that can be explained as the simply ‘sum’ of their components. For example, the addition of an acid and an alkali creates salt and water, while the fusion of an ovum and spermatozoon produces a conceptus. These are transformational rather than additional processes, which resist simple, mechanical interpretations.

Is the Human Body Redundant?

The increasing ‘liveliness’ of machines and accessibility to the virtual world has raised questions about whether it is possible to uncouple the mind from the body in through a host of different strategies. The basic idea is that if we are able to escape the ties of our own flesh then we can upgrade them and even replace them with immortal ones. Performance artist Stelarc has made some of the most extreme and enduring work on this subject. The artist characteristically depersonalises his anatomy and claims that it is not only an object that can be subjected to re-designing but is also ‘obsolete’. During his performances, Stelarc mentally ‘vacates’ his own body to prove its obsolescence, and claims that his body is no more than a site for redesigning and re-engineering the human form.

In my view, Stelarc’s work paradoxically highlights the profound importance that embodiment holds for being human. When Stelarc dissociates his mind from his body he demonstrates its sheer plasticity and robustness. The artist then recolonizes the body with robots, communications technologies and soft prostheses as proof of this inbuilt physical redundancy. Yet the machines he hosts are given context by the presence of a body – for in its absence, they are just a collection of machines devoid of meaning. Moreover, redundancy is a characteristic of complex systems, which are a form of organization that does not obey the Cartesian, dualistic laws that govern machines. The artist’s rejection of these qualities simply highlights that the human body is not a machine.

There is nothing liberating about having an anesthetized body, nor one that is functionally redundant. While Stelarc’s suspensions and performances demonstrate that we can temporarily ‘forget’ our bodies in order to explore a transcendent state of being, there are those who live in a permanent state of disconnection.
