DNA strands of well-defined sequence are valuable in synthetic biology and nanostructure assembly. Drawing inspiration from solid-phase synthesis, here we describe a DNA assembly method that uses time ...

Extracting regularities from temporal sequences of events is central to human cognition. By identifying patterns, people form predictions about upcoming events. If, when waiting at a train crossing, ...

Many digital-communications systems use non-return-to-zero (NRZ) signaling, and system designers have created many NRZ test patterns to test and verify their products. These patterns usually either ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...
