JPG to Video Software.

Can anyone recommend a *FREE* Windows program for converting a set of .JPG images from a time lapse sequence into a video format, preferable GUI rather than command line (a la ffmpeg) orientated.Continue

Effect of temperature on slime mould growth.

Started this discussion. Last reply by AndyGadget Oct 15, 2021. 2 Replies

I haven't started growing a slime mould yet but I was wondering if anyone has studied the effect of temperature on physarum polycephalum. I've seen temperatures of 20 and 25 degrees C as normal…Continue

All,  I've just had a message via the forum from a Joseph McLaughlin which bears all the hallmarks of a spam message of the '419' variety; an invitation to share in a large sum of money BUT you will…Continue

Daywalker on the prowl.

I've not done anything with slime moulds for a while but today decided to take Daywalker out for a run in a simulated wild environment.  This is the starting point; a supermarket mushroom container with various woodland goodies, rotting pear and apple with fungus, compost and a squirt of fermenting seaweed-based fertiliser.  There's a pinch of oats in there with the spores to give Daywalker a good breakfast when it wakes up, and the container will be covered with clingfilm to retain moisture…See More

Maizie V Larry

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!See More

Can Physarum polycephalum detect a magnetic field?

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 food lay in…See More

Maizie, Day 4.

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 :¬)See More

What is your interest in slime moulds? (we need to know you're not a bot or spamster)
I've always been an avid nature watcher with a particular interest in the weirder side of things and was just reminded recently of slime moulds (which out-weirds most things) by a TV documentary; The Blob - A Genius Without a Brain. I've recently retired so have more time to pursue my enthusiasms and have a few ideas on amateur level research so would like to join the group to give and receive feedback.

Another time lapse brewing.

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.
