Discussion Overview

The thread discusses the sharing of science-related photos among participants, focusing on various scientific phenomena and experiments. The scope includes personal projects, experimental results, and playful interpretations of scientific concepts.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant shares photos of a blood shoeprint and a saliva amylase test, inviting others to contribute their own scientific images.
  • Another participant mentions a SEM photo of Al doped zinc oxide nanopowder, noting its insufficient magnification for thesis inclusion.
  • Discussion includes a photo of diffraction patterns from a pinhole experiment, with one participant creatively altering the typical experiment to create a smiley face.
  • Participants discuss the construction of transgenic C. elegans, detailing specific genetic constructs and their implications for research.
  • One participant describes capturing a moiré pattern from a CRT display, inviting others to replicate the phenomenon.
  • Several participants express interest in various scientific images and experiments, with some engaging in light-hearted banter about the content shared.

Areas of Agreement / Disagreement

Participants generally agree on the enjoyment of sharing scientific photos, but there are multiple competing views on what constitutes a "scientific enough" image. The discussion remains open-ended with no consensus on specific definitions or standards.

Contextual Notes

Some discussions involve assumptions about the legality and appropriateness of sharing certain types of images, particularly regarding sensitive subjects like biological specimens. There are also unresolved questions about the technical aspects of the images shared.

Who May Find This Useful

Individuals interested in scientific photography, experimental science, and creative interpretations of scientific concepts may find this thread engaging.

I haven't found a thread with this topic so I thought I'd start one.

i'll start by posting these photos. Hopefully they are scientific enough. :biggrin:

Blood Shoeprint.

Saliva Amylase test.

Post yours! :smile:

Come on, I know I'm not the only person with scientific photos lying around. I know there are other scientists around here.*looks under some rocks (but only finds some earthworms)*

Post post post! :biggrin:
 
Which ones the sperm one.

The so called http://www.imep-cnrs.com/docu/charcoal.pdf as found in a hole, we dug in the Maatheide, close to Lommel in Belgium at only ~1 meter depth.

Okay, this is one of the SEM photos of Al doped zinc oxide nanopowder... I'm not including it in my thesis, as you can tell the magnification is not enough. :biggrin:

Nice picture. I don't think we have a SEM in our school. Interesting to see.

Them? You mean the penguin of course. :biggrin:

Very nice, Andre. Were you digging the hole to intentionally look for the charcoal soil layer?

None are of the spermatazoa test. I'm not sure if it's legal to post! :

Nice science related photos. Hope to see more!

Neither do we, haven't you noticed the French note! :biggrin:
I've send the samples to one of the schools there, I mean France, my prof recommend it.

Them? You mean the penguin of course. :biggrin:

Yes ~c~ it was the purpose of that hole and we knew we were going to find it

What's the thesis on? TCOs? Photovoltaics?

Neither, it's a bit odd from what you've expected. I study the effect of changing the Sol Gel [which is a chemical synthesis route] growth parameters on the structural and optical properties of ZnO nanomaterials...

Do I have to go public! :biggrin:

When I saw this thread, I thought I must post one of my daughter's elementary school "properties of light" project photo, but Andy beat me to it!

I got bored with the typical pin hole and double slit thingy, so I made a smiley face... LOL

:smile: from a smiley about half that size. But it made an interesting picture.

That's so cool Ms Music... Can you make the [biggrin] face? :biggrin:
 
  • #15
Very nice Ms Music. I went to a Fourier transform applet site and drew in a smiley, and took a screen shot...look how close mine is to yours!

If you want to play with the applet, it's here -

Two images you might find interesting, guess what they are :smile:

I'm guessing a GFP-transfected c. elegans. What's the construct?

Yes, these are transfected and integrated (by gamma radiation) constructs. Simplified, the constructs are the following:

1) myo-3-promotor::GFP (GFP expressed in the body wall muscle cells)

2) generic-promotor::mCherry::H2B (Cherry marking histones in all cells); hypodermal-promotor::GFP::TBA-1 (alpha tubulin marked in hypodermal cells); myo-2-promoter::GFP (GFP expressed in the pharynx, an easy to visualize marker for transgenic animals).

Oh my... Thank you Lisab, that is VERY entertaining! I just may wind up wasting my entire Friday afternoon with that applet. Much MUCH easier than making teeny pinholes and razor blade slits. And now drizzle can make his/her own big grins. It DOES appear to have the same results as all my photos with the different pinholes or slits. The biggrin IS interesting, but a kitty face is even cooler. Must not lose my job must not lose my job must not lose my job...

Very nice- do you/your lab make the constructs? I'm wondering specifically about the GFP::TBA-1...
 
  • #24
Wow Lisa :!) VERY entertaining indeed, thanks. I thought of doing a dotted circle, amazing!

Of course, my BIG grin :biggrin:

Yes we make the constructs ourselves and if certain transgenics already exist, we just cross the strains to make doubles. It really is a miracle that you can attach GFP to a tubulin monomer and have it form a functional molecule. There is a concentration dependency though, you need to titrate the amount of construct you inject in order to get transgenics, too much of it is toxic to the cell. The second picture was just a snapshot of a worm that I took when I was screening for double homozygotes of the transgenes, you should see the cells in division! Unfortunately I can't show such a picture, those pictures first need to be published somewhere else :smile:

I guess this is a science-y photo- see if you can figure it out:

http://a.imageshack.us/img821/9960/teevee.jpg

I was playing around with the autofocus feature and decided to point the camera that our TV (crt display). When it focused, the moire' pattern appeared in the viewfinder- it's a pentaprism, not a LCD display- even though I could not see it normally.

It's definitely real- it moves depending on the orientation of the camera to the tv, and is not part of the electron beam- I took a series of exposures at 1/30, 1/60, 1/125, etc... and the pattern remained.

It was tricky getting the image re-scaled; the pattern is quite sharp and distinct- try to capture the phenomenon yourself- it was trivial with autofocus.

Any ideas?

Mouse trap!

No CRT here to check, but looks interesting.

Is it scientific enough? That's just a rock on the Swedish coast, but if you know what you are looking at, traces of the ice age are obvious. It is not just this rock, all rocks around have similar marks, and all point in the same direction. This particular picture was taken around N 58 deg 45' 32.31" E 11 deg 10' 51.87", but plenty of similar places around.

heh... yeah, I needed a white screen to get the best contrast. That is an intro shot from "Between the Lions"...
