At the core of the particle is the viral DNA that is surrounded by an icosahedral capsid. Between the capsid and the envelope is an amorphous layer referred to as the tegument. It is in this ...

In a new study, researchers have finally answered this question, providing the first definitive neutron diffraction evidence of antiferromagnetism in a real icosahedral quasicrystal. This ...

DNA and proteins are known in traditional biochemistry ... which encloses the viral genome. Many viruses have icosahedral capsids and, by virtue of symmetry and therefore of a well-defined local ...
