A virus is a sub-microscopic infectious agent that is unable to grow or reproduce outside a host cell. Each viral particle consists of DNA or RNA within a protective protein coat called a capsid.Some of them can cause human diseases and even cause death.Here are molecular structures of different virus capsid.The capsid shape varies from simple helical and icosahedral (polyhedral or near-spherical) forms, to more complex structures with tails or an envelope. Isimulated them using different... continue reading

flash and drop watersI take many photos about drop waters. To freeze them in their dropping time, you’d better use the flash of your camera.
