hi,I've been experimenting with the Physarum for the past few months, and the results showed that the P. Polycephalum shrinks every time it is exposed to hard white light. Does anyone know if this…Continue

Light: how affects it the Physarum?

hi,I've been experimenting with the Physarum for the past few months, and the results showed that the P. Polycephalum shrinks every time it is exposed to hard white light. Does anyone know if this happens because the Physarum decides to shrink every time, or because it dies a little bit every time? Greetings, MarijnSee More

Time-lapse programs

Hey,I'm working now on a research on the Physarum where we examine its growth as an effect of periodic lighting. The only problem is now, that we have a reasonably good webcam (logitech pro 9000), but that when we use a time-lapse program with it, it is horribly pixelated. Does anyone know a time-lapse program that has also a good resolution?? As you can deduct from the video below, we could really use it!…See More

As some might have noticed, I've been working on a schoolpaper (we call it a profielwerkstuk) and we've finally finished it, so here down below you can download our final paper. Have to warn though, we did not exactly manage to do everything we wanted to, but I think it still might be interesting and inspiring to read it. In it is also described a very good method for culturing the mould. Hope you'll enjoy!…
