It slices, it dices, it silences: ADAR1 as gene-silencing modular RNA multitool
RNA, once considered a bit player in the grand scheme by which genes encode protein, is increasingly seen to have a major role in human genetics. In a study presented in the April 25 issue of the journal Cell, researchers from T ...

This spot on Mercury (almost) never goes dark
Mercury, traveling in its 88-day-long orbit around the Sun with basically zero axial tilt, has many craters at its poles whose insides literally never see the light of day. These permanently-shadowed locations ...

Pushing the boundaries of transcription: A new level of variation in messenger RNAs exposed
(Phys.org) —Like musicians in an orchestra who have the same musical score but start and finish playing at different intervals, cells with the same genes start and finish transcribing them at different ...
