Even with the advent of streaming video, Blu-ray Discs may yet escape the fate of obsolete Betamax videotape cassettes. A team of engineers at Northwestern University has shown that Blu-ray movies can be converted into inexpensive templates for efficient solar cells (Nat. Commun. 2014, DOI: 10.1038/ncomms6517).

Researchers have long known that arrays of nanostructures can boost solar-cell efficiency. Patterns that are too random . . .
