Living Machines

From a macro to a micro landscape. The plants have a different time comparing to ours and our relation with the nature goes in many different ways.

I am doing a research in ‘green spaces’ in Holland with a specific interest in artificial landscapes as Botanical Gardens, green houses and plants, within the nature in cultural aspects, their own behavior and how the nature is interfered by man. The botanic systematization, the dissemination of different species all over the world and dialogs between natural and artificial processes are also subjects in my field of research.

This research of the landscape is a continuation with GEMA project that I have been developing in Rio, since 2007. This research involves natural and urban environment, the change of the landscape through the time due to the cities expansions. How we can have a better living with our environment instead of killing it using the technology we have nowadays? The next step for nature is engineering, creating a self controlled environment and recycle the resources. I am researching also about plants and politics into a bio-scientific sphere. The Mata Atlantica forest was destroyed by the uncontrolled growth of the cities and now Amazonia is also in danger. There are several multi-national companies in Amazonia: a cycle of destruction that starts killing the trees of the forest for agronomy, cattle raising, scientific researches, trafficking of plants, and so on. It is estimated that 15% of the Amazon has been deforested.

There is also a discussion about the internationalization of Amazonia forest which is a political aspect. A dispute of territory is going on and how an artistic practice can make a thought about this relevant issue.

The research about resources of the nature started with professor Bert van Duijn, from the Biology University in Leiden for a couple of months in how we can measure the action potential of the plants.

One of the plants that we are measuring the action potential is the Venus Flytrap. The matter that intrigues me most is the speed of its action: with this carnivorous plant we are able to see its movement in real time, reacting to insects that triggers the movement of its leaf.

The Venus Flytrap is one of a very small group of plants capable of rapid movement, such as Mimosa, the Telegraph plantSundews and Bladderworts. Its trapping structure is formed by the terminal portion of each of the plant’s leaves and is triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves contacts a hair, the trap closes if a different hair is contacted within twenty seconds of the first strike.

Diagram of the inner surface of  the Venus Flytrap showing some of the sequence events leading to the trap closing: [1] a trigger hairs bent over; [2] the touch sensation is translated into electrical code, known as a receptor potential, which is confined to just the sensor cells inside the trigger hair; [3] a sufficiently large receptor potential fires a fast-moving electrical wave, known as action potential, which spreads across the trap lobes, [4] the trap doesn’t move, but somehow remembers being touched; [5] another hair (or the same as before) is bent over; [6] a second receptor potential is fired into the sensor cells; [7] a second action potential is fired across the trap; [8] if the second action potential comes roughly within 35 seconds of the first one, the trap is sprung shut. The cell on the outer epidermis expand rapidly, folding the trap lobes over. If no prey is caught, the trap reopens about 12 hours later. But if an animal is trapped, the trap slowly tightens around its prey, secretes digestive juices, and absorbs the remains of the animal over about 1-2 weeks.

Another plant that I am studying to develop a work is the Mimosa Pudica (Sensitive Plant). Its a plant that developed a kind of camouflage/protection. When they suffer any change in their surrounding the ActionPotential changes.

Some points raised while doing the project:

>> machines and plants

>> living machine design

>> engineering ecology

>> the biological equity determine design

>> design be coevolutionary with the natural world

>> design be sustainable through the integration of living systems

>> building and design help in healing the planet

>> working as a concert

>> biotics relationships

>> reshape and redefine our tools and technology

I was invited to realized this project at V2 – Institute for the Unstable Media, in the summer residency 2010, to develop this work with Bert van Duijn, Hortus Botanicus from Leiden and V2 team.

My position is to investigate this phenomena and create an art piece; in van Duijn’s laboratory, to develop scientific researches for our future.

Once we could get data from the plant, I did my first try-out transforming these numbers into sound:
