Unique Microscope Captures Motion of DNA Structures in Space, Time

Pasadena, CA (Scicasts) – Every great structure, from the Empire State Building to the Golden Gate Bridge, depends on specific mechanical properties to remain strong and reliable. Rigidity―a material's stiffness―is of particular importance for maintaining the robust functionality of everything from colossal edifices to the tiniest of nanoscale structures.
