Single-cell multi-omic detection of DNA methylation and histone modifications reconstructs the dynamics of epigenomic maintenance - Nature Methods
This work presents scEpi2-seq, a method for simultaneous single-cell profiling of DNA methylation and histone modifications, enabling direct investigation of the interplay between these two epigenomic marks.

Pressemitteilungen - Die Wissenschaft braucht moderne Personalstrukturen und mehr Dauerstellen | WR gibt Anstoß für einen Kulturwandel
Der Wissenschaftsrat (WR) fordert eine grundlegende Reform der Personalstrukturen im deutschen Wissenschaftssystem. Das Ziel sind attraktive, vielfältige Stellen mit klar strukturierten Entwicklungsoptionen, die die Wissenschaftseinrichtungen in der Konkurrenz um Fachkräfte sowie im internationalen Wettbewerb stärken. Nötig ist ein Personalgefüge, das den immer stärker ausdifferenzierten Anforderungen an die und aus der Wissenschaft gerecht wird und attraktive Dauerstellen ergänzend zur Professur bietet.
