Bizarre that our 2020 #Drosophila #AMP review already feels out of date.

Thanks to #AnnualReviews to cover the many updates in the field and present a much more complete picture of the diversity, mechanisms, topics, of fly immunity re: host defence peptides.

“Harvard geneticist David Reich said … increasingly sophisticated analysis of genetic material made possible by technological advances shows that virtually everyone came from somewhere else, and everyone’s genetic background shows a mix from different waves of migration that washed over the globe.”

We have created a new DNase I- & ATAC-seq peak caller that uses an adaptive background model that controls for copy number variation & aneuploidy. It performs a per-nucleotide test (+FDR correction) and is very fast. Please try it out and give us feedback!

Chromatin ist nicht unbeweglich. Es handelt sich um ein hochdynamisches Material, dessen 3D-Struktur zentrale genomische Prozesse – von der Transkription bis zur DNA-Reparatur – steuert. Doch wie verhält sich Chromatin als Material – als Flüssigkeit, Feststoff oder viskoelastisches Gel –, um diese Funktionen in lebenden Zellen auszuführen? Ohne eine Antwort auf diese Frage können wir nicht vollständig verstehen, wie Chromatin bei Krankheiten gestört wird.
