100gb and counting

Two cameras, and four days of shooting at 20 second intervals leads to an awful lot disc space taken up. So far I've just done a rough render - take the whole damned lot and turn it into one movie file. Now I can see the massive deficiency in using the study rather than the workshop for shooting - every time I tread on a floorboard the camera moves. 

Easy to fix by tracking a couple of points in the images but tedious and slow. 

The huge advantage of using something like an SLR…

A new hope...

I've been shooting time lapses all week - all in Petri dishes and all of them have messed up due to condensation so I'm trying something different.

Somewhere in this box, amongst the moss I meant to add and the slugs, spiders and mites that just came along for the ride is a load of . 

The base is a paint tray  full of potting compost packed down hard two large colonies of  physarum on paper covered with  moss, rotting wood and grass seedlings. I'm hoping after a day in the dark…

Having a series of failed experiments here

but then, it wouldn't be proper science if it worked straight off. Back to the soldering iron, or the gin and tonic.

Just arrived, a USB sound card, an op amp, several jack plugs and a spool of platinum wire. Slime, you're gonna get probed :-)

Why slime?

I started getting into Physarum last year - I've worked with the cellular slime mold dictyostelium before and I was asked to prepare some slime mold time lapse footage for some public lectures.  Seeing as we'd finished the dicty work and they're quite dull I decided to get a more entertaining organism. Once I'd finished the film footage I'd grown quite fond of them and started keeping a culture or two going in the lab, and then at home.

I work with microscopes- my day job…

Need cultures of Physarum polycephalum

I have a visiting scientist (Dr. Hanh Tran) from Vietnam who is spending this academic year at the University of Arkansas. She is currently working with Physarum polycephalum.  We have the Carolina Biological strain and one wild strain collected locally but would like to have 2-3 additional strains. If anyone could send me a small portion of a sclerotium in an envelope, it would be greatly appreciated. My mailing address can be found on the University of Arkansas web site.

Biology teacher new to Slime Mould Co. with some questions.

Hi everyone! I am new here and am wondering if there are any other teachers who use slime mold in their classes. I teach AP biology at a high school in Phoenix, AZ, and am interested in incorporating slime molds into my classes in reference to cell communication.

I am also curious how and where you order slime mold.

Sime Mould photography

Hello.  I am a photographer who specialises in fungi and nature photography.  In my search for fungi I often come across slime mould and I find it fascinating.  I do not grow the slime mould in Petri dishes, but I do sometimes observe the growth on old fallen wood or other substrate, as it competes for food with other animals, plants or fungi.  Here are some still photos I have taken of some of our local (Eastern Australian) slime mould.…

Thanks for contributions to slime mould TED talk

Thanks to everyone who contributed to my slime mould talk at the recent TEDSalon Berlin event. The slime moulds (and me) were warmly received! Here's a mini review from the event:

I'll post notes and links from the talk here soon.

My Slime Mould doesn't grow anymore!


I am trying to grow my Slime Mould, it was growing great but suddenly stopped. I think it dried out, so I add some boiled water (cold), cleaned the Petri Dish and gave it new oats, nothing happened. Then I change to a agar base, but nothing happens. Maybe I used the wrong agar, but it stopped growing and I think its getting really mouldy. :(

Here is a picture of my pet in the agar.

Here is the link of the process: …

Being Slime Mould: part 3: enactment

If you are in Rotterdam on Friday 27 September we are running an experiment to see if humans can follow a few simple behavioural rules of the plasmodial slime mould in order to communicate, navigate and cooperate. 

We are inviting people to participant and become a human slime mould super-cell, or come along to observe what happens.

EVM and Physarum

 I have found that the use of EVM (Eulerian Video Magnification) can improve looks and shape of physarum videos. I therefore give an URL of a split screen EVM which I have recently done.

slime moulds need reviving...

I recently received two nice and healthy petri dishes of Physarum from the USA to work with, but after a few days, and almost overnight, they changed from lively succulent plasmodium specimens to sclerotium, and have been totally static for days. I have rehoused parts of them in fresh agar filled petri dishes but they are also inactive. I even added a drop of purified water to see if they were in need of rehydration, but still no change. I am rather traumatised that I have not looked after…
