The JPEG

Some autofluorescence under UV illumination of an antihistimine in water. 40X/0.60 - Olympus BX50 upright. I don't see a huge difference in image quality, but I wasn't using the confocal this time. If I get some time I'll do a more thorough comparison. This sample was a little thick for widefield fluorescence and I didn't take a z-stack so couldn't deconvolve it. Oh well.

top one looks slightly more detailed to me tbh.

in that kinda "move away from the monitor and squint, "hmm maybe"" kind of way of course.

Yeah, perhaps. I didn't zoom in either. There might be some difference upon closer examination. I didn't have enough time to fool around that much. It was kind of neat to see "live" on the camera because you could see the water moving and dissolving particles. The other thing that's cool is that you don't often see more than one colour with autofluorescence using the same emission filter (in this case, DAPI)...but enough play. I have to run off to a seminar and then I get to do some FRAP this afternoon and tomorrow. Live cells are way more fun to play with than pharmaceuticals.

I'm not sure what makes tornadoes so fucking scary. I suppose because their path and what they do is fairly unpredictable.

Figured I'd post a video

3D Theoretical view of what the Universe looks like from the outside looking in.

Many of the shots you'll see of certain galaxies whilst traveling away from our sun (you travel from our sun to the edge of the Universe at the speed of light,) were taken by Hubble Deep space and then rendered onto a 3D Plane. I think it's pretty cool.

I saw really cool evidence of the Primordial Field Hypothesis (put forward by Bruce Depalma and Nikola Tesla) in this interesting little Tesla Coil that doubled as a Guitar Amp. Whenever a note was plucked, electricity arced out into the air, and hit the exact note played on the guitar.

I need to go find that video now.

If ever I became famous... screw actual amps I'm just using this. That's wicked.
