This week's bout features Maizie the Physarum polycephalum against Larry the Lichen (heritage unknown).  Larry is the heavyweight and the younger of the two at a mere 250 million years but it's thought the agility and experience of Maizie (600 million years) will win through.  This could turn nasty.    

Ding ding!…

There is a paper detailing how a slime mould can be guided by loading it with ferromagnetic particles and steering it with magnets, but I was wondering whether an un-modified physarum could detect a magnetic field.

I ran a set of 4 time-lapses using a strong magnet (top of picture) and starting conditions as shown in the photo so heading towards the pole would give it a guaranteed food reward.  I would expect the slime to preferentially set off towards the pole if it 'learned' that…

Just starting off another time lapse.

I mentioned before that the Physarum seemed to take a long time to get going on the art paper substrate I was using.  It did speed up after a bit and I was wondering if it had begun to disregard an unpleasant substance in the paper.  The experiment I've just started is to see if this may be the case.

Slime mould A is from the previous run on the art paper.

Slime mould B has only been exposed to clean kitchen tissue.…

This is my Physarum Polycephalum exploring its Petri dish over the space of 3 days.  One second of video time equals 30 minutes of real time.

Maizie's Travels.

This is a 3D printed template for cutting an 85mm disc to sit in the bottom of a Petri dish.  

STL for this is on Thingiverse : https://www.thingiverse.com/thing:5047067

Still work to do on getting the best from the camera.  Exposure is unstable (yes, auto-exposure is off) and I can probably get better quality from  it, but tweaking is the fun part.  The video was taken at 1 minute intervals over a day and a half.

As for the Physarum, I was trying watercolour art paper which is fairly absorbent if soaked but suspect there is something in there that the slime doesn't like as it's developing much more slowly than a slime growing on kitchen tissue in a…

I'm looking to keep my slime mould experimentations in a cupboard so designed and 3D printed a compact time-lapse rig using a microcontroller camera (ESP32-CAM).  Only goes to 1600x1200 pixels and quality isn't great so doesn't stand too much magnification, but fine for watching the overall growth patterns of the slimy beast. …

I rehydrated Maizie on Thursday and she's already trying to escape to pastures new. 

(OK, I know they have over 700 sexes or whatever, but it's a she :¬)

interesting post

Hello everyone!

I went to the forest the other day and tried to forage some slime.

I found this on decaying wood, grabbed them, and took them home to some Petri plates with coffee filters (I'm aiming to grow them in agar), I'm not sure if what I have here is P. polycephalum (giving the intense yellow color). Could someone help me know if I'm on the right track???  …

Hi, guys!
I am a student of the Academy of Fine Arts, and I want to design slime molds for my graduation project. I want to combine the feature of slime molds automatically choosing the optimal path into the tailoring of clothing.
Any other thoughts?
Please give me some guidance and advice!
I also welcome friends from different majors to discuss with me.

It choose one way to the oats. But I don't know why, also the weather is so dry, I need watering it…

The top side is Yakult milk, below is water. slime molds didn't find the oat in Yakult immediately.

So happy today, I received the sharing slime molds from UK. Now I'm still waiting it grow…

What's the best way to get a timelapse of slimemold growth? I know they grow better in the dark, so I'd hesitate to illuminate them at all times for camera footage. Any ideas of best cameras, best timelapse softwares for phones, or other ideas for getting a good timelapse? What have people done in the past? Thanks!

I am trying to grow some "daywalker" slime onto a canvas for an artwork. Do you guys have any tips for growing slime mold this way?

A cool youtube channel I follow called "Journey to the Microcosmos" just put out a new video on slime mold

Should garner more interest in slime and very informational too
