SIRT1, a cellular metabolic sensor, transcriptionally promotes sphingomyelin degradation in embryonic stem cells, which in turn modulates their membrane fluidity and neural differentiation.
The structure of the mechanosensitive channel MscS embedded in a lipid bilayer redefines the nature, location and importance of lipid–protein interactions in the gating of mechanosensitive channels.
The newly developed antibody-free techniques, HepG4-seq for G-quadruplexes and HBD-seq for R-loops, robustly reveal the comprehensive maps of native G-quadruplexes and R-loops, as well as their roles in transcriptional regulation.

A theory is presented that explains why some ion channels tend to open in response to membrane stretching, which posits that channel closing is disfavored by the morphological energetics of the lipid bilayer, and increasingly so under lateral tension.
Unlike mouse embryos, mouse embryonic stem cells are able to use a SAS-6-independent pathway for imperfect centriole biogenesis that is associated with a rich centrosomal milieu and robust PLK4 activity.
