Rotavirus particle, artwork and TEM

Rotavirus particle. Computer artwork (left) and coloured transmission electron micrograph (TEM) of the geometric structure of a rotavirus particles capsid shell. The capsid of a rotavirus has 5-fold symmetry (shown by 5-line star at left and right), and is icosahedral in shape. An icosahedron has 20 triangular sides; five of these meet at the apex at the centre of the star. The cylindrical units at left (which correspond to the green areas at right) are capsomers, the protein units that make up a capsid. Inside the capsid is the genetic core of the virus. Rotavirus viruses can cause severe diarrhoea in children, killing hundreds of thousands worldwide every year. A rotavirus particle is around 70 nanometres in diameter

EDITORS COMMENTS
This print showcases the intricate beauty of a rotavirus particle, combining computer artwork and a coloured transmission electron micrograph (TEM). The geometric structure of the virus's capsid shell is revealed in stunning detail. With its icosahedral shape and 5-fold symmetry, the rotavirus capsid is truly mesmerizing. The star-shaped figure at both ends represents the 5-fold symmetry, indicating that five triangular sides meet at the apex located in the center. These triangular sides form an icosahedron with a total of 20 faces. The green areas on one side correspond to cylindrical units called capsomers, which are protein components composing the capsid. Within this elegant structure lies the genetic core of the virus, responsible for causing severe diarrhea in children worldwide. It is disheartening to know that this tiny viral particle claims hundreds of thousands of lives each year. Measuring only about 70 nanometers in diameter, this image reminds us how something so minuscule can have such devastating consequences. Its false-colored presentation adds depth and enhances our understanding of its biological makeup. This extraordinary visual representation serves as a reminder not only of the complexity and fragility inherent within our bodies but also highlights ongoing research efforts aimed at combating these deadly pathogens.
