We scanned an oyster shell for the convenience of being able to model over it.

We also talked about modeling our cage design after the following structure.  When originally talking about our designs we were considering the structures be made of Calcium Carbonate.

In addition to this, while at the ‘Holy Spat’ talk, we realized that the current cage design is simply an inconvenience and what if that entirely was redesigned to accommodate the culture and cultivation of oyster forming and oyster reef rebuilding.  A similar structure to the jack toys was considered as our design model. As a structure that reaches from the inside to the outside, it allows wheel build up to maximize its volume and grow off of each other.

A Week 12: Perspective on Culture as Medium exhibition

 

DSC_0417
Recently, I had the pleasure of attending Culture as Medium, curated by Margaret MacDonald(pictured above), during the opening reception at Motor House on April 1st, 2016.
Culture as Medium is a show utilizing a double-entendre for culture, the show operates at the intersect between the study of microbes, and artistic application. I found the show to be a successful attempt at identifying, and ultimately dissolving a cultural boundary between canonically scientific content, and artistic practice. The show is being hosted at both Motor House, a show-space, and Baltimore Under Ground Science Space (BUGGS), serving to further dissolve the societal construct between art and science. Each of the works showcased at Motor House had varying levels of community engagement, and were produced by artists who utilize biology as inspiration.

Tal Danino, a scientist-turned-artist offered an installation playing with microbes as a visual medium. Working with various bacteria, the installation consisted of 3 monitors running visuals derived from manipulated bacteria, operating in conjunction with a rotating slide projection of curated bacterial samples from varying species, as well as a grouping of more slides, giving viewers the opportunity to engage with the slides and serving to further highlight the variety in scale between the projections, the actual slides, and the monitors. It also allowed for viewers to see the actual specimens and the beautiful diversity of color in the work. This work is particularly successful at removing the constraints between what is art and what is science, the practice required to develop this imagery is canonically rooted in science, but the results are visible, and palatable; this is taste that allows for a familiarity between a casual viewer and bacteria that extends beyond the stasis of a textbook, and the sterility of microscopy.

Ryan Hammond, unlike Tal Danino is an artist-turned scientist. Hammond’s work consisted of a wooden box, housing a setup including a monitor, a joystick and living paramecium. Offering an opportunity for viewer participation, the work functioned utilizing a natural quality of the paramecium. Paramecium naturally move in response to electric stimuli, and within the paramecium housing unit the artist had set quadrants that correspond with the access of the joystick; as viewers moved the joystick the paramecium moved in response, allowing for the viewer to control the paramecium. Of particular interest to me were the conversations that surrounded the work. I had the pleasure of witnessing a debate between a viewer who was also a physicist, and Ryan Hammond, the debate beginning with the ethical question, do we have a right to essentially play games with a life form. The debate then opened up to a larger discussion first questioning anthropocentrism, and later discussing the concept of free-will, ultimately coalesqueing into the question on how to define sentience, and the value of life itself. As a side note, this work also helped facilitate a conversation with Nick, a child at the show, who claimed that “Germs are bad, they make people sick.” Because Nick had played with these “Germs” and felt a familiarity with them he and I were able to have a discussion with him about bacteria and his ethical point of view in a way that hopefully wasn’t too boring for him. The ability of this work to be available and palatable to someone not professionally engaged with artistic or scientific spheres of influence is particularly impressive to me.

Francois Lapointe was also featured in the Motor House exhibit. His work operating as both performance, and scientific experimentation, Lapointe presented viewers at the opening with two works. The first work visible in the show being several boards with documentation of an ongoing performance he has been doing in which he measures the changes in his micro-biome after engaging in 1000 Handshakes. He has performed this several times, including a performance walking around Baltimore, which he performed April 2nd, the day after the opening at Motor House. The other work Lapointe presented was a live performance/experiment. Donning a lab-coat, and with the help of his lovely and competent assistant, Lapointe performed a Kimchi Eating Performance, in which he ate only Kimchi for an extended period of time, periodically swabbing samples of his tongue in order to track the effect the kimchi has on his micro-biome. The performance was particularly entertaining considering his visible distaste for kimchi, allowing him to fully activate the idea of sacrifice in the name of art and science. While Lapointe has a performative practice rooted in scientific ritual, there is something to enjoy about how approachable he was, viewers were encouraged to speak with him during the act, offering a friendly face, and casual banter. This was my favorite part of his work considering it allowed me to connect the concept of the micro-biome and the potential effects of environment in real time on the micro-biome, as well as offering an experiment packaged as a person with which I can sympathize, ultimately fostering a period of self-reflection upon my own micro-biome and habits.

All of the works in the Motor House opening of Culture as Medium were, in my humble opinion, very compelling, and well curated given the theme of the show. Unfortunately I have yet to see Anna Dimitriu’s work at BUGGS, however if it is anything like the work on her website (http://annadumitriu.tumblr.com), then I expect to be similarly wowed. While I have focused mainly on my motor house experience, there is much more history and influence that was requisite for the show to be as successful as it was. If you are so inclined feel free to watch Margaret Macdonald’s talk (https://www.youtube.com/watch?v=Rk6NpBmpK90)  on how she thinks and her process of producing an exhibition as an experiment.

 

Week 11: Group Projects and Culture as Medium

 

In the morning of  April 5th,  our class had a follow up discussion on Margaret MacDonald’s exhibition Culture as Medium. At the opening in Motor House, many of the students from Biofabrication participated in assisting performance and initiating provocative conversation

The exhibition Culture as Medium blurs the boundaries between science and art, artists and scientists. As François-Joseph Lapointe states, “For me, experimental science and experimental art are two branches of the same tree, identical twins separated at birth.” Tal Danino’s series of Microscopic Bacterial Videos (on view at Motor House) imparts the haunting beauty of the synchronized dynamic behavior of bacteria while revealing cutting edge research in synthetic biology. To produce Sequence Dress (on view at BUGSS), Anna Dumitriu immersed herself in whole genome sequencing research of clinically important bacteria in order to, as Dumitriu writes, “artistically explore the emerging technology of whole genome sequencing of bacteria and consider what it means to us personally, culturally and socially.” With his performance experiment, 1000 Handshakes (to be performed in Baltimore on April 2, 2016), Lapointe creates what he describes as “metagenomic self-portraits” or “microbiome selfies” that illustrate the metamorphosis of his bacterial self as he shakes hands with those around him.

In the afternoon, the class broke into three research groups(Body as site of manufacturing, Machine as site of manufacturing and Outdoors as site of manufacturing) to further discuss the idea and research as our research papers and presentations are due the next class meeting.

Week 10: Group Projects and Visitor Thomas Burkett

In class, on March 29th, we began by breaking up into our groups to continue discussing the ideas and research collected over the past few weeks.  Ryan Hoover greeted each group to review our ideas for project references and material possibilities.

During the second half of the class, we had the pleasure of meeting and speaking with Thomas Burkett, one of the founders of BUGSS. BUGSS, Baltimore Underground Science Space, was created for anyone interested in Biotechnology, to learn, collaborate and hang out with people equally excited by the potential of this field.  This was an excellent opportunity to ask questions about how he opened up the non-profit space as well as share our project ideas for valuable feedback.

Week 8: Presentations // Establishing Group Projects

 

Sarah Whelton's Presentation
Sarah Whelton’s Presentation

In class on 3/8, we each gave presentations answering the following 5 questions, in order to highlight common themes and interests, and help us establish research groups.

Prompt:

  1. What is the most interesting thing you’ve learned in class so far?

2. What is a project from another artist/designer/researcher that uses biology in a way  you find inspiring?

3. What is an approach to manufacturing (loosely interpreted) that you find compelling?

4. Describe an intersection of biology and another discipline that you find exciting.

5. What do you want to continue to explore?

 

After the presentations, we discussed some of the recurring themes from our presentations, including the role of synthetic biology in art and the role of art in synthetic bio, open source (in general), Open Source Gendercodes, sustainability, etc…

We then divided into three groups under the general titles:

  1. Body as site of manufacturing (formerly the “visual” team) [C.B., A.B., S.K., B.K.]
  2. Machine as site of manufacturing [A.F., M.R., E.K., S.C.]
  3. Outdoors as site of manufacturing [J.O., G.B., E.W., S.W.]

 

“What’s Up Daniel Grushkin!”

We were lucky enough to have one of the Biodesign Challenge’s top ‘team’ members in our midst for the entirety of class. He spearheaded a lot of the discussion and helped push in the right directions w/ regard to group formation. He came equipped with inspiration…here’s his bio:

Daniel Grushkin is a former fellow at the Woodrow Wilson International Center for Scholars, where he researched the field of synthetic biology. He is an Emerging Leader in Biosecurity at the UPMC Center of Health Security. He cofounded Genspace, the world’s first community laboratory. Fast Company ranked Genspace among the top 10 most innovative education companies in the world. As a journalist, he reports on the intersection of biotech, culture, and business for publications including Businessweek, Fast Company, Scientific American, and Popular Science.”

 

Week 5: Bioprinting

In Week 5 we started our introduction to bioprinting by manually writing gcode to draw our intitials with a pen using a Prusa 3d printer. We then worked with Ryan Hoover’s Xylinus tools for Grasshopper (a visual scripting plug-in for Rhino) where we learned to write a script the could produce gcode directly in grasshopper, which also allows much more manual control than programs like Slic3r and Cura – something that will be useful when creating gcode for bioprinting. In the afternoon we got an overview on using a pneumatically driven syringe for bioprinting which we will be using in the coming weeks.

  • Pipette Etiquette
  • USE A LOT OF TIPS. WHEN IN DOUBT CHANGE THE TIP.
  • do not leave the lid of pipet tip holder open after grabbing new tip.
  • units we used in the lab: mainly micro-liters
  • Microliter – µ1 -.000001
  • Liter – L – 1

 

 

 

 

 

 hot plates 

  • rapid heating, heat shocking – (thermometer must be in water)

 incubator

  • an enclosed apparatus providing a controlled environment for the growing of microorganisms under controlled conditions

 autoclave 

  • performs sterilization through steaming/heat

*IMPORTANT: keep thing sterile in the lab, gloves – don’t touch face, mouth etc./pipet etiquette/do not drop things on the floor 

centrifuge

  • machine with a rapidly rotating container that applies centrifugal force to its contents, to combine or settle 

 


II. Overview of our first project in the lab

In this lab, we take DNA sequences for GFP (Green Fluorescent Protein) from fluorescent jellyfish, and catalyst its production; then combine with E Coli. cells – in theory, producing colonies that would soon fluoresce under black light.

Week 2: Synthetic Biology, in silico

We began class on 2/2/16 with learning about the namesake of the primary Grasshopper Tool that our class will be primarily using through the Semester, Alba.

“Alba” is the name of a genetically modified rabbit created by artist Eduardo Kac, with help from French Geneticist Louis-Marie Houdebine in 2000. By using a Green Fluorescent Protein (GFP) ordinarily found in Jellyfish, Alba is able to glow entirely green under Blue Light.

 

Afterwards, we dove right into leaning Ryan’s Alba Grasshopper Suite. We are using the scripting component of Grasshopper combined with resources from BioBricks to fully understand DNA and the ways we can interact with it in this rapidly developing field.

For example,  we can use several visualizers to show us the base pairs, and amino acids of a particular Promoter.

In the first Alba Grasshopper definition we created, we simply visualized the Amino acids and Base pairs of a Green Fluorescent Protein (E0040) into the Rhino Viewport.

1st Alba Definition

 

In the Second Definition we worked with,  We visualized the Green Fluorescent Protein again into the Rhino Viewport, but we learned how to highlight the subsections in the DNA. Using the visualizer, we highlighted the promoter of the Green Florescent Protein.

2nd Alba Definition Highlighting Promoter

 

In the third Definition we created, we practiced running Digestion ad Ligation within Alba. We essentially laid out what we were going to do in the lab later after lunch. We visualized the Digestion of the GFP Plasmid with the Pstl and the Xbal Enzymes, and the digestion of the Lacl plasmid with the Pstl and the Spel enzymes. Afterwards, we visualized the ligation of these two plasmids together.

3rd Definition, Digestion and Ligation

You can see in the Rhino viewport how we selectively cut out certain sub sections of DNA to eventually Ligate together.
