We have recently explored some simple DIY methods for making your own plankton nets. See more info about various methods for microbe hunting on the wiki-page “The Art of Hunting”
According to some tips from Brandon Ballangée and Brian Degger, we found some great and cheap methods. Primarily relying on different mesh in stockings/panty hoses aka “Strumpf” you can filter out the right sizes of plankton. The little container at the end of the net is very practical to accumulate all the larger stuff that doesnt get through the mesh and can then easily be replaced and sealed with a new lid to take the samples further. We used clean urine-sample puts from the drug-store, approx 15 Cents, stockings ( 50 Cents), cheap wire and steal band ( 30 Cents), a cheap thread/rope and some hot glue… total cost is less than 2 €, compared to 150 €, it’s quite good! The stockings dont last to long though and tend to get holes quite quickly.
Always remember to bring maaaannnnyyy extra contrainers with you on a field-trip. there cant be enough! And a waterproof marker-pen!

Last week we were doing the first expedition into the Karst caves around Ljubljana. While they are famous for their beautiful geological formations, the dark and cold waters of these caves are also the habitat of the Proteus anguinus, also called “Human Fish”. But is there more other life down there? To check this we went for a µ-Cave Safari, equipped with DIY laser-projectors, MobileLabs, plankton-nets, starving low-nutritious agar culture plates and other fun stuff to carry around in the muddy holes.

To the Cave
After we packed all our gears, got a last bite of some mesni burek and put on our cave-man shoes we headed towards the cave “Vranja Jama”, crossing the Planinskega polja, near Logatec, our cave sherpa Doms’ hometown. We were eager to explore what microscopic lifeforms there might be…
“We suspect that, because limited but chemically complex nutrients enter the cave system, very few microbial species are capable of encoding all the necessary uptake and catabolic reactions to support growth. To overcome this limitation, selfish competition for resources is replaced by cooperative and mutualistic associations, such as have been seen in biofilm communities.”
- from “What’s Up Down There? Microbial Diversity in Caves”, Barton et al
What we found
Of course, next to investigating the microscopic life of the cave, we also saw the “Human Fish” (german name is “Grottenolm”) and we wont hide our brilliantly sharp picture of it . Besides that, we found loooaads of earthworms in the mud, moths, spider webs, some fungi and bones of various animals (maybe bats).

Do-it-yourself microscopy has proven to be a perfect medium for dipping into a couple of key concepts, fundamental methods and relevant discourses with new media students. In my class at the Bauhaus-Universität Weimar during the winter term 2012/2013 the given task was to build a cheap (affordable would be an understatement) microscope. The task also [...]
A small intellectual and cultural movement composed of young science and engineering professionals, students, advocates, hobbyists and enthusiasts who are organizing to create public awareness about the current technologies in the biological and chemical sciences which can be applied in one’s own backyard or garage.

In the idyllic place, near the small city of Tolmin, there is a perfect place for festivals. Every year there are several festivals going on (MetalCamp, River Reggae Splash,…) and one of them is Festival Sajeta, where experimental music is met. And now, bio-hacking is part of it
We are doing some simple stuff. [...]
During our recent discussions we thought we have to look more deeply in to cheese making. While first experiments were already done by Sachiko during her visit to lifepatch in Yogyakarta, (see impressions on facebook here), this time we’ll try it under the minimal equipment circumstances in Hagen.
