Piezoelectric 'taxel' arrays convert motion to electronic signals for tactile imaging

Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.

Threaded through a nanopore - single-molecule detection in DNA

Changes in the bases that make up DNA act as markers, telling a cell which genes it should read and which it shouldn't. A British team has now introduced a new method that makes it possible to enrich the rare gene segments that contain the modified base hydroxymethylcytosine and to identify individual hydroxymethylcytosine molecules in DNA.
