Frederiques plants

Here are some pictures of my plant experiment after one week.  All the seeds  with the cotton in the glove have grown. While some other seeds that had less cotton, but more growth factors have not (yet) grown that well.

How do I make the pictures visible? When I use upload I don’t see how I can put my pictures with this post.

moral doubts

I was just wondering if some of you felt the same after the experiments we did in the class:

Allthough in the class I really made up my mind and decided to manipulate the butterfly, at home when I explained what we did I felt I couldn’t really justify why I did it.  I gave the whole class a second thought and then it occured to me that the main reason I did it was out of curiousity.

Can curiousity alone make you forget initial moral limits?

Hereby some photographs and movies made during lesson 4.

Drosophila experiment:
We used yeast to make a drawing inside of a petri dish, and released drosophila (fruit flies) inside of the dish. We could choose between hungry flies (males and females would likely start eating) or well fed flies (probably only the females would start eating). I chose the hungry ones, and recorded the movements of the flies for one hour and twenty minutes. The playback speed of the movie is increased by both twenty times and a hundred times.

.

I also included two macro shots of the flies.

Altering the wing pattern of live butterflies:
We also got the chance to try to change the wing pattern of a Bicyclus anynana butterfly ourselves, after reading about it in Marta’s paper “The Artificial Natural: Manipulating Butterfly Wing Patterns for Artistic Purposes”. We used very fine needles to make precise punctures around the barely visible eyespots of the pupal, with the intention to change the final pattern of the wing.

Image nr.3 shows one of the caterpillars Marta brought, image nr.4 shows a pupal just after it was punctured with a needle, image nr.5 shows a cocoon with the wing already quite visible and image nr.6 shows a detail of the wing of a Bicyclus anynana.

This one reminds me of the mastercard logo. I’ll post some more pics tomorrow.
