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. LASSA VIRUSES are ss RNA viruses (family Arenaviridae) causing severe haemorrhagic disease. They are enveloped (greenish layer in this image) and studded with (red) protein spikes. Beneath the envelope (lipid bi-layer) lies the matrix protein (Z protein, shown in blue) and deeper to this the RNP (shown in yellow). Zoonotic (spread from animals to humans) with rodents as the main host. See some high resolution still images of Lassa virus. With thanks to Ed Rybicki. Useful links: |
