Can tiff images fade over time?

I have some images of an experiment I did last summer in a lab, and I was recently asked for them to verify some results. I had converted only a few of them to jpegs, and today when I went back into my folder I found that all of the tiffs had gone white! The bands are still visible, but only barely... Why are the jpegs okay and the tiffs not? Is there any way I can restore them?

Evidence:

The same exact picture, but saved as a jpeg (last year)

Also, if you know of anywhere/anyone else where I might get help, please do let me know. I don't want to have to repeat the experiment just because I can't see the pictures!
Sorry - these links should work
