a map of every place i’ve visited since 2004

[posted: ]  [0 comments]

when i moved into the new apartment, my aunt and uncle gave me a 170×110 cm world map for my hallway, and i immediately knew what i wanted to do with it: mark every trip abroad and append a photo.
over the holidays, i’ve finally been able to work on this project again.

here’s the current status, covering (i think) all destinations since 2004, plus a few bonus vacations dating as far back as 1995.

time lapse: protective leaf movements of oxalis acetosella

[posted: ]  [0 comments]

here’s part of the results of an experimental stress physiology class that i took last summer…
in what must have been one of the most open-minded classes i ever took (meaning that we could really influence the topics and experiments), my friend barbara and i studied three aspects of the common wood sorrel (oxalis acetosella): protective leaf movements, photo inhibition and heat resistance.

the following time lapse video shows protective leaf movements, which are a “deliberate” reaction of this little plant to a sudden input of intense, direct sunlight:

 

on the base of each of three leaflets, turgor controlled pulvinar cells function as a hinge to increase or decrease the leaf angle of the leaflets. such nastic leaf movements can be triggered by a number of exogenous factors such as light (photonasty), temperature (thermonasty) but also by internal
factors.

the concluding course discussion was held as an inofficial “conference of alpine stress physiology”, with poster presentations of all participants.
you can find more information about our oxalis experiments in barbara’s and my scientific poster: Leaf movements, photo inhibition and heat resistance in Oxalis acetosella L. (PDF)

young me/now me

[posted: ]  [0 comments]

young me/now me is the title of a very unique project by ze frank, in which people from all over the world have sent in childhood pictures and recent reenactments thereof.

here’s my submission:

young me: murano, venice in october 2002 now me: murano, venice in august 2010

i first visited murano/venice on a high school trip in october 2002. i think i was trying to immitate a napoleonic posture.
the 2010 picture is from a very hot august day in 2010.
it seems i’ve always found cargo pants practical.

since both pictures were taken with digital cameras of mine, i guess this one could also be called “young digicam, now digicam”.

kinder für kinder: charity project for ugari, kenya

[posted: ]  [0 comments]

dear reader, please allow me to introduce our charity project:
my friend simon spent a volontary year as a teacher in a small, rural school in kenyas outback, so to speak. there is neither running water nor electricity available in the little village of ugari, kenya, some 300 km west of nairobi.
after his return, we (the wilten boys’ choir) organized a charity concert, which provided money to build some much-needed infrastructure for the secondary school, which had just been set up in an unfinished classroom.

one year after our charity concert, on october 24th, we are organizing a second concert in innsbruck, during which we will try to collect more money for ugari, as well as present the changes in ugari within the last 12 months. it’s safe to say that A LOT has changed!

i’ve put quite some time and effort into the project lately, so i wanted to point you in the direction of our new website slash blog:
Kinder für Kinder – Wiltener Sängerknaben für Ugari

screenshot: kinder-fuer-kinder.at

there’s some information in english, if you don’t happen to speak german.

if you’d like to support our aim, there are several ways you can do so – from donations to sponsorship. please contact me if you’re interested in helping.

animation: watching hair grow

[posted: ]  [2 comments]

since facebook aparrently doesn’t allow animated profile pictures, i figured i’d share this here instead:

a little "project" i did in 2004/2005

it’s the animated gif-version of a little “project” i did in 2004/2005, basically a 12-month time-lapse video with awful temporal resolution.

sterile plant culture

[posted: ]  [0 comments]
the tip of a carnation shoot (dianthus sp.) is taken and ridded of all the leaves, except the primordial leaves

about one year ago, i took part in a laboratory class where we learned various methods related to artificial plant reproduction.
one of the exercises was to create meristem cultures from a carnation plant (dianthus sp.), under sterile conditions.

from each shoot of the plant, we removed the developing leaves on the tip, almost down to the meristem (the few primary cells that constantly divide into more cells). we stopped the exraction at the smallest primordial leaves, placed the tiny piece of plant material on culture medium (in test tubes, under sterile conditions), added a cap to the tube, and sealed it with parafilm.
the following weeks, it was positioned beneath a daylight lamp, and after the experiment was finished, i asked if i could take one specimen home with me.

march 16th: meristem culture about two months after the procedure. development of root tissue.

considering that it’s an almost completely closed system, i didn’t expect little william the carnation to last this long: the plant grew and grew until it reached the top, and i’ve just recently placed it upside down, so that it could grow “upwards” again.

two notes:
most people don’t consider that, in darkness, plants need to “breathe” just as animals do (as in: use O2 and release CO2), so the gas contents are probably still OK, if only limited. (also, i’m assuming that parafilm isn’t able to stop slow diffusion of gas molecules completely.)

supposedly getting low on fresh nutrients, the plant seems to have given up on the lower leaves so that it could develop new ones. the old, withered leaves do not decompose since there aren’t any microorganisms in the system.
