We study, in the context of quantum information and quantum communication, a configuration of devices that includes (1) a source of some unknown bipartite quantum state that is claimed to be the Bell state Φ and (2) two spatially separated but otherwise unknown measurement apparatus, one on each side, that are each claimed to execute an orthogonal measurement at an angle θ ∈ {−π/8, 0, π/8} that...

Overexpression of Brf1, a transcription factor of the RNA polymerase III apparatus, can transform cells in vitro and cause tumor formation in vivo. Marshall et al. (2008) now show that one of the transcriptional products of RNA polymerase III, the initiator tRNA(Met), mediates this effect, revealing an unexpected role for this tRNA in tumorigenesis.
