The Physarum Experiments - in conversation, Sunday 15 January, London

Posted on January 9, 2017 at 13:50 0 Comments

Next Sunday afternoon I'll be in conversation with Natalia Zagorska-Thomas at Studio ExPurgamento, Camden, about interspecies creativity, control and authorship when working with living organisms.
The event is free but space is limited so please rsvp to reserve a place. There will be drinks. Hope to see you…

Let me know if you can help..

Hello, Heather, Please read a comment on my page. What is this?

Hi Heather,

My name is Gus, a postdoc researcher at Dartmouth College, USA, working on Biocomputing. Our group just stepped in this field and want to discover how different sound/music affect the growth of slime mode. I like you Ted talk and your comments in "the creeping garden"!

Do you know any agar plate (especially prepared ones) can grow Physarum Polycephalum without using oats? I see that normally people have to put oats in the agar, but for my experiment, I'd rather not use oat because it will block/affect the shape. In other words, I am looking for agar plates where the nutrition evenly mixed with the agar is enough for the growth. Could you give me some advice? 

Thanks a lot!

Hi Heather,

Great to meet you the other week in London.

Would you be interested in sending a high quality image or two of a slime mould experiment/art you have been working on that we could include in our exhibition?  Are any possibly for sale that would benefit from being displayed?  Thank you, Rosie

Please let me know about the research lab actively working in physarum polycephalum.

I am interested to join the lab.

thank you

Yes it survived for a few weeks, died last week :( Where do you get it from? And those are the photos I took, Josh has some too!

Hi Heather,

Thanks for your comments about my blog.

I hope you don't mind, but I have made an informative short entry about your visit here.



At 12:45 on November 25, 2011, Rafaela Miranda Rocha said…

hmm i see. well, i kept it out of light completely and it had plenty of food nearby, just never reached it... But yes, as I said, would love to give it another go so if you can send another plate to nathan that would be great! thanks!!

At 21:37 on November 23, 2011, Rafaela Miranda Rocha said…

hi heather,


unfortunately, my slime mould died :( It turned into black spores overnight! And from what I heard from the other people, most of theirs didn't make it as well. I would really like to try it once again - do you think there's any way I can arrange to get another sample? cheers

Hi Heather, Thankyou for your welcome, and what a great site! We loved your workshop and the appoach of your artistic practice. I hope the pictures I posted do the workshop justice. Sadly my own culture died before it got started - maybe it got jolted on the journey home, but it has withdrawn completely and has shown no signs of life. I feel like a murderer.

I had the same problem with B. utricularis sclerota.  B. utricularis seems to touch oats and then streams away.  I believe it prefers rotting wood because it is looking for bacteria to eat, it also loves to eat paper products like brown cardboard (paper towel tubes).  I currently don't have any B. utricularis because it died with my termite culture and am writing all this based on memory. 


I am guessing that slimoco is free to join and there are no membership fees because I haven't seen anything that says otherwise.
