Silicon chips have powered computing for half a century. Increasingly, they are also becoming platforms to read and manipulate biology at scale—recording from many neurons, reading many DNA sequences ...

Because these capabilities are under genetic control, the history of a metastasis is characterized by complex gene-expression patterns, which cDNA microarrays are well suited to track. Single-stranded ...

Fifteen years into the microarray revolution, biochip images – row upon row of red and green spots on a field of black – have become as ubiquitous as DNA gels once were. But how are those pictures ...
