Study is first to show some tRNA introns affect gene expression

Nature - A comprehensive analysis of the cell-specific molecular regulatory mechanisms underlying post-traumatic stress disorder in the human prefrontal cortex.

A new study has revealed that chemical tags once regarded as genetic clutter are in fact powerful gene silencers – and removing them could unlock safer treatments for inherited blood disorders.

We show that cancellation of internal forces together with spatially uncorrelated noise generically enforces a universal $1/s$ scaling of the center-of-mass (COM) diffusivity for polymer segments of contour length $s$, independent of model details. Within…
