<p>Hi All,</p>
<p></p>
<p>I am a master's student at Carnegie Mellon University working on a project with a collaborator involving usage of slime molds to simulate gentrification in a city. Both my collaborator and I are complete novices in terms of using slime molds so this site is an invaluable resource.

<p>Hi All,</p>
<p></p>
<p>I am a master's student at Carnegie Mellon University working on a project with a collaborator involving usage of slime molds to simulate gentrification in a city. Both my collaborator and I are complete novices in terms of using slime molds so this site is an invaluable resource. We had a couple of questions about the implementation of our project and would greatly appreciate any assistance:</p>
<p></p>
<p>1) our current plan is to have the slime mold grow over a vacuum formed topology of a city environment, and systematically introduce food sources as certain metrics indicating gentrification change/expand over time. attached is an image of prototype we are testing to see how the mold traverses the vacuum formed material (styrene). next to the sytrene model is the cnc milled wooden model of the same topology--we put a dormant slime mold on there as well and some food just to see what would happen. we are storing both of these models in a dark enclosed box with a cup of water present to provide humidity.</p>
<p></p>
<p><a href="http://storage.ning.com/topology/rest/1.0/file/get/1093033789?profile=original" target="_self"><img width="750" src="http://storage.ning.com/topology/rest/1.0/file/get/1093033789?profile=RESIZE_1024x1024" width="750" class="align-full"/></a></p>
<p></p>
<p>question: is styrene a sub-optimal material for slime mold to grow on? if so, would covering the styrene in agar allow the mold to survive, but gravitate towards the food sources? does the thickness/application technique of agar layer matter?</p>
<p></p>
<p>2) we want to place a projector underneath our model and use projection mapping to show a color map of various gentrification related metrics on the topology.</p>
<p></p>
<p>question: given the light sensitivity of physarum, would this be problematic? can we minimize/eliminate this problem by only using light of particular wavelengths/intensities?</p>
<p></p>
<p>we really think this project has the possibility to turn out very cool, and would sincerely appreciate any assistance or advice y'all could give us.</p>
<p></p>
<p>Thanks!!</p>

<p>So it seems lots of people want to start experimenting!</p>
<p>You can buy Physarum culture kits and specimens from educational/biological suppliers.</p>
<p>I know of (and have used) the following:</p>
<p>US: Carolina Biological </p>

<p>If you know of suppliers in other parts of the world, please add them below...</p>
<p></p>
<p>Just found these online (not used before):</p>

<p></p>
<p>The kits often come with instructions for experiments, but you can also find these online, for example: <a href="http://www.sciencebuddies.org/science-fair-projects/project_ideas/MicroBio_p028.shtml#summary" target="_blank">http://www.sciencebuddies.org/science-fair-projects/project_ideas/MicroBio_p028.shtml#summary</a></p>

<p>Happy experimenting! And please share your results on slimoco...</p>

<div><span style="font-family: tahoma, arial, helvetica, sans-serif;" class="font-size-3"><b>Preferred conditions:</b> dark and damp (for example: petri dishes or tupperware in a shoe box or similar, with a damp base - paper towels or agar base).</span></div>
<div><span style="font-family: tahoma, arial, helvetica, sans-serif;" class="font-size-3"><b>Food likes:</b> favourite food is porridge oats, doesn't mind starchy stuff like rice and pasta. Best to give sterilised (i.e. boiled) food, so it doesn't go mouldy as quickly. I often boil flaked oats to make a paste and keep it in the fridge.</span></div>
<div><span style="font-family: tahoma, arial, helvetica, sans-serif;" class="font-size-3">The slime mould itself is harmless, but the food you give it will go mouldy (just usual food mould) so some care is needed, and your pet physarum slime mould should move to a new clean environment on a weekly basis.</span></div>
<div><span style="font-family: tahoma, arial, helvetica, sans-serif;" class="font-size-3">Its <b>top speed</b> is approximately one centimetre an hour, so not exactly a spectator sport, but its beautiful growth patterns are clearly visible and easily captured with time lapse photography. My films are shot at various frame rates, from one shot every 20 seconds to one every 5 minutes, depending on what I want to show.</span></div>
<div><span style="font-family: tahoma, arial, helvetica, sans-serif;" class="font-size-3">If you want to capture <strong>protoplasmic streaming</strong> (the inner pulse of <em>Physarum polycephalum</em> which transmits nutrients and chemical signals) chose a frame rate of less than 90 seconds as that is the approximate duration of the pulse in each direction.</span></div>
