A description is given of the ENCODE effort to provide a complete catalogue of primary and processed RNAs found either in specific subcellular compartments or throughout the cell, revealing that three-quarters of the human genome can be transcribed, and providing a wealth of information on the range and levels of expression, localization, processing fates and modifications of known and previously unannotated RNAs.

Chromosome conformation capture carbon copy (5C) is used to look at the relationships between functional elements and distal target genes in 1% of the human genome in three dimensions; the study describes numerous long-range interactions between promoters and distal sites that include elements resembling enhancers, promoters and CTCF-bound sites, their genomic distribution and complex interactions.

The radially outward flow of plasma from the Sun is expected to be deflected when it meets the flow of interstellar plasma through which the Solar System moves, but the spacecraft Voyager?1 unexpectedly finds that the deflected, meridional, flow is consistent with zero within the transition region.
