Nature in Architecture by Michael Pawlyn

In this TED Talk, designer Michael Pawlyn of Exploration discusses the advantages of biomimicry for the future of architecture and design. Pawlyn begins by citing a few examples of nature's own inventive ways of adapting to specific climate needs and indeed, makes a very clever analogy out of this evolutionary advantage:

"You could look at nature as being a catalog of product's and all of those have benefited from a 3.8 billion year research and development period, and given that length of investment, it kind of makes sense to use it."

Throughout the talk, Pawlyn uses examples of existing technologies and projects that learn from nature's example and use bio-mimicry to solve what he sees as the three necessary steps to becoming truly sustainable:

1. Radical increases in resource efficiency
2. Linear to closed loop systems
3. Fossil fuel economy to solar economy

Perhaps the most intriguing indictment against us is expressed in Pawlyns second step - the comparison of our current method of resource use versus the way nature does. Our current mode of design, consists of extracting resources, turning them into "short-life products", and then disposing of them. However, this contrasts greatly with the way nature uses resources. In the natural model, everything that is created is used, - the waste generated in one system, is used for energy in another. By altering our current mode of design to a "systems" model, we are able to add value to waste, which is currently now a completely negative by-product.

Ice-Nine, Or How to Grow Concrete from Bacteria

In Kurt Vonnegut's 1963 satirical novel Cat's Cradle, the protagonist follows the trail of a brilliant researcher's children who hold with them ice-nine - a chemical invention small enough to be carried under the fingernail, but potent enough to freeze all water on earth solid. The element is described as a "seed" that alters the atomic composition of liquid:

"There are several ways", Dr. Breed said to me, "in which certain liquids can crystallize - can freeze - several ways in which their atoms can stack and lock in an orderly, rigid way." That old man with spotted hands invited me to think of several ways in which cannonballs might be stacked on a courthouse lawn, of the several ways in which oranges might be packed into a crate. "So it is with crystals, too; and two different crystals of the same substance can have quite different physical properties."

He goes on to describe the stacking process:

The theoretical villain, however, was what Dr. Breed called "a seed". He meant by that a tiny grain of the undesired crystal pattern. The seed, which had come from God-only-knows-where, taught the atoms the novel way in which to stack and lock, to crystallize, to freeze. "Now think about cannonballs on a courthouse lawn, or about oranges in a crate again", he suggested. And he helped me to see that the pattern of the bottom layer of cannonballs or of oranges determined how each subsequent layer would stack and lock. "The bottom layer is the seed of how every cannonball or every orange that comes after is going to behave, even to an infinite number of cannonballs or oranges."

And of course, the prolific advantages are described alongside the horrific consequences:

And that old man asked me to think of United States Marines in a Godforsaken swamp. "Their trucks and tanks are wallowing", he complained, "sinking in stinking miasma and ooze." He raised a finger and winked at me. "But suppose, young man, that one Marine had with him a tiny capsule containing a seed of ice-nine, a new way for the atoms of water to stack and lock, to freeze. If that Marine threw that seed into the nearest puddle...?" "The puddle would freeze?", I guessed. "And all the muck around the puddle?" "It would freeze?" "And all the puddles in the frozen muck?" "They would freeze?" "And the pools and the streams in the frozen muck?" 'They would freeze?"

In 1963, Vonnegut pondered both the possibilities and the dangers of such technology through dark humor, the absurd, and the profane in this story of invention and the human hands that guide it. In 2010, however, the potency of this allegory is all to familiar as science, theory, and invention is constantly redefining the ability of humans to solve problems.


For the annual iGem synthetic biology contest, a group of students at Newcastle University have engineered BacillaFilla - a type of bacteria that, once inserted into a concrete crack with the proper growing media, will germinate and produce a "mixture of calcium carbonate, levan glue and filamentous cells" that will densify and "activate concrete repair". Eerily, the scientific name for the compound is called Bacillus Subtillus 168. According to the team:

BacillaFilla repairs concrete by producing a mixture of calcium carbonate, levan glue and filamentous cells in the cracks. Once we have applied BacillaFilla spores onto the concrete surface, they will start germinating in the presence of media. Once the cells have germinated, they will start to swarm down the crack. At the bottom of the crack when they reach a high density, they will use subtilin quorum sensing to activate concrete repair. BacillaFilla repairs concrete by 3 different processes:

1. Some of the cells with produce calcium carbonate crystals,
2. Some of the cells will become filamentous thereby acting as reinforcing fibres in the crack and
3. All the cells will produce Levans glue which acts as a binding agent and at the same time it fills up the whole crack.

Interestingly, the bacteria only work through a swarming process whereby the bacteria propel themselves to reach the point of germination. Also, almost in a pre-meditated response to detractors and grey-goo fear-mongers, the team has implemented a genetic "kill-switch" to stop the spread of bacteria.
Of course, the ability to repair concrete from within is as exciting as the potential for a runaway concrete-producing super-bacteria is alarming. Material technologies such as this blur the lines between natural phenomena and synthetic architecture, border on Utopian ideals and science-fictional dystopias, and represent bold new ideas in research and development.

Carnivorous Tomatoes and Passive Consumption

"Feed me Seymour!" While compiling a report on carnivorous plants to celebrate the bicentenary of Charles Darwin's birth, researchers at the Royal Botanical Gardens Kew have made a shocking discovery that many common plant species are, in fact, carnivorous. Unlike many familiar carnivorous plants such as the infamous venus fly-trap and the pitcher plant which are highly specialized and actively catch and consume prey, many other plants consume prey through more passive means. For instance, many common varieties of the tomato plant are covered in thick sticky hairs that will catch and contain small aphids and other insects.
However, lacking an external apparatus to consume the trapped insect, it has been found that the plant will wait for the insect to decompose and fall to the ground, fertilizing the soil. According to the report:

Domestic varieties of tomatoes and potatoes retain the ability to trap and kill small insects with their sticky hairs and are likely to absorb the nutrients through their roots when the animals decay and fall to the ground.

Among other common plant species found to behave in a similar way are several different varieties of potatoes, ornamentals, and even the petunia. It is interesting to note the long-term strategy of the plants. Where most carnivours are documented as predators who hunt/trap their prey to consume it immediately, this discovery shows that some carnivors will actually invest in a long-term solution that works through improving the local environment. While most predators ingest prey and benefit exclusively from the meal, the predator that lacks an instrument to intake directly must enrich the soil and only benefit indirectly. This idea of passive consumption is a philosophy that could find potential in other fields of science or development. Could the construction industry or energy producing sectors benefit from a philosophy of long-term passive consumption? It seems plausible that more localized long-term indirect investments could help to produce better yields not just for the industry, but also for connected economies and environments.

Of Fish and Communicative Movement

When large schools of fish travel through the water, the body operates with three simple rules of movement; collision avoidance, side-by-side locomotion, and distance metering. The school of fish, sometimes numbering into the thousands, is able to act as one unit because each individual fish is able to maneuver through the water in any direction in close proximity to it's neighbor without colliding. Nissan is using this natural ability of individuals safely navigating within a group as a model for a next-generation vehicle communication and movement system. According to Nissan:

"fish demonstrate extraordinary "anti-collision" abilities, navigating instinctively and intelligently through challenging terrain by detecting and avoiding obstacles"

Enter the EPORO. Well, actually, enter a lot of EPORO. As they move around, the small group of robots are able to communicate with each other based on the three simple rules of the school; collision avoidance, side-by-side locomotion, and distance metering. Nissan hopes that in the future, this communication based behavior could lead to more efficient and safe vehicular travel in heavy traffic situations. The application may also have potential in other industries such as urban design and development, weather information monitoring, and disaster relief response. Previously disparate objects, areas, and populations could become communicative networks that respond in real time with their environs and with each other.

In their 1971 project entitled Truckstop Network, the ever-experimental information nomads, Ant Farm, proposed a system of user-feedback devices connected across the interstate system of the US. The network of video screens and communication devices envisioned the users across the system interacting and responding to concurrent events taking place at the other truckstop locations. Large screens would project live video feeds, and continuously updated information boards would list ride information, events, and news. Here, the infrastructure itself, though 'virtual', serves as the empowering element in the system rather than occupying a typical subserviant role based on pure function.

morpho butterfly

The wings of the morpho butterfly remain bright and shiny throughout the butterfly's entire lifespan. The vibrant color is created by light refraction rather than pigment. The tiny scales that make up the wing membrane are made of layers of protein that refract light in many different ways, so the color seen is that of reflected light.
According to Ask Nature, an advanced fiber company Tenjin Fibers Limited has begun to manufacture fibers mimicking this structure. The resultant fibers require no pigments and resist fade. The color shades and brightness are created by the thickness and frequency of structural layering.
