Rediscovered letters and postcards highlight the fierce competition among scientists who discovered DNA's famous double-helix structure and unraveled the genetic code. Francis Crick and James D.

A self-organisation is an universal phenomenon in nature and, in particular, is highly important in materials systems. Our goal was to develop a new theory that provides a computationally effective ...

IMAGINE DNA. Chances are, the double helix leaps to mind. Ever since James Watson and Francis Crick proposed this elegant structure in 1953, the image of two gracefully intertwined ribbons framing the ...
