To see the stereo effect, please gaze at infinity at a point between the two images. You should eventually see three images. The middle image will be a combination of the left and right images and it should look solid (stereo or 3d). The effect can sometimes be improved by holding a sheet of paper or card perpendicular to the image pair so that your left eye only sees the left image and your right eye only sees the right image. To focus, move your head closer to or further from the image. It might take a few tries to achieve the effect.
Mimiviruses: largest known viruses (even bigger than some single-cell organisms). They are icosahedral and contain a double stranded DNA genome. The capsid is covered by fibres (fibers) that radiate outwards imparting a bacteria-like outer surface to the organism. In fact it takes up the Gram stain (like Gram positive bacteria) causing early confusion. Mimivirus has been implicated in some cases of pneumonia. Originally found in amoeba.
