text: We perform precision measurements on a Mott-insulator quantum state of ultracold
atoms with tunable interactions. We probe the dependence of the superfluid-to-Mott-insulator
transition on the interaction strength and explore the limits of the standard
Bose-Hubbard model description. By tuning the on-site interaction energies to
values comparable to the interband separation, we are able to quantitatively measure
number-dependent shifts in the excitation spectrum caused by effective multibody
interactions.

text: We investigate local three-body correlations for bosonic particles in three
dimensions and one dimension as a function of the interaction strength. The three-body
correlation function g(3) is determined by measuring the three-body recombination
rate in an ultracold gas of Cs atoms. In three dimensions, we measure the dependence
of g(3) on the gas parameter in a BEC, finding good agreement with the theoretical
prediction accounting for beyond-mean-field effects. In one dimension, we observe
a reduction of g( 3) by several orders of magnitude upon increasing interactions
from the weakly interacting BEC to the strongly interacting Tonks-Girardeau regime,
in good agreement with predictions from the Lieb-Liniger model for all strengths
of interaction.

text: Nuclear pore complexes (NPCs) assemble at the end of mitosis during nuclear
envelope (NE) reformation and into an intact NE as cells progress through interphase.
Although recent studies have shown that NPC formation occurs by two different
molecular mechanisms at two distinct cell cycle stages, little is known about
the molecular players that mediate the fusion of the outer and inner nuclear membranes
to form pores. In this paper, we provide evidence that the transmembrane nucleoporin
(Nup), POM121, but not the Nup107–160 complex, is present at new pore assembly
sites at a time that coincides with inner nuclear membrane (INM) and outer nuclear
membrane (ONM) fusion. Overexpression of POM121 resulted in juxtaposition of the
INM and ONM. Additionally, Sun1, an INM protein that is known to interact with
the cytoskeleton, was specifically required for interphase assembly and localized
with POM121 at forming pores. We propose a model in which POM121 and Sun1 interact
transiently to promote early steps of interphase NPC assembly.

text: As the gatekeepers of the eukaryotic cell nucleus, nuclear pore complexes
(NPCs) mediate all molecular trafficking between the nucleoplasm and the cytoplasm.
In recent years, transport-independent functions of NPC components, nucleoporins,
have been identified including roles in chromatin organization and gene regulation.
Here, we summarize our current view of the NPC as a dynamic hub for the integration
of chromatin regulation and nuclear trafficking and discuss the functional interplay
between nucleoporins and the nuclear genome.
