Intra-clone variability and change in accessibility
We computed the mean and variance of log-transformed signal fold changes for each chromosome in a single clone to understand the global changes in accessibility . To control for high fold changes caused by error in windows with low read counts, windows in which neither the clone nor the parent has more than 200 reads were excluded from this calculation.

Wide-spread brain activation and reduced CSF flow during avian REM sleep - Nature CommunicationsNon-rapid eye movement (NREM) sleep is associated with increased cerebrospinal fluid (CSF) flow in mammals, but this link has not been studied in birds. Here, the authors show that in pigeons, REM sleep is associated with activation of visual brain regions and a drop in CSF flow, suggesting that REM sleep functions occur at the expense of waste clearance during NREM sleep.

Vesicular glutamate transporters are H+-anion exchangers that operate at variable stoichiometry - Nature CommunicationsIn glutamatergic neurons, synaptic vesicles contain glutamate, but not aspartate. Here, the authors show that vesicular glutamate transporters are H+/anion exchangers that attain high selectivity for glutamate via variable transport coupling.

Ultraviolet radiation shapes dendritic cell leukaemia transformation in the skin - NatureBlastic plasmacytoid dendritic cell neoplasm (BPDCN) arises from clonal (premalignant) haematopoietic precursors in the bone marrow, and BPDCN skin tumours first develop at sun-exposed anatomical sites and are distinguished by clonally expanded mutations induced by ultraviolet radiation.
