NAD+ Metabolism Licenses Zygotic Genome Activation via PARP7‐Mediated ADP‐Ribosylation of UHRF1 in Mouse Early Embryos

open access: yesAdvanced Science, EarlyView.
This study uncovers a metabolic‐epigenetic axis licensing zygotic genome activation (ZGA) in mouse embryos. A developmental decline in NAD+ levels activates PARP7, which mono‐ADP‐ribosylates and stabilizes UHRF1. This modification promotes the establishment of permissive histone acetylation marks, thereby facilitating timely ZGA.

Low Fertilities before the Fertility Transition:

open access: yes
This chapter reconsiders the relationship between low fertility and demographic transition by examining childlessness and very small families in a pre-transition society. Focusing on Zeeland, a Dutch province in the nineteenth century, it challenges the conventional view that childlessness and two-child families were primarily products of modernization,

Interfacial Water Coordination on Ruthenium Oxide Nanoparticles Confined Within Covalent Organic Framework and Its Effect on Electrochemical Nitrate Reduction

open access: yesAdvanced Science, EarlyView.
We demonstrate how oxygen‐deficient ruthenium oxide (RuOx) nanoparticles confined within covalent organic framework achieve highly efficient nitrate‐to‐ammonia conversion. Strong interaction between RuOx nanoparticles and COF results in modified interfacial hydrogen‐bond water network and adsorption of nitrogenous intermediates.

MIS12 Is Required for Kinetochore‐Microtubule Attachment in Oocyte Meiosis

open access: yesAdvanced Science, EarlyView.
A model depicting the role of MIS12 in K‐MT attachment during oocyte meiosis. The presence of MIS12 stabilizes bipolar K‐MT attachments by maintaining the function of NDC80 and its interaction with TUBB. This, in turn, promotes KNL1 assembly and subsequent SAC protein recruitment to kinetochores.

Fluid Fertilizers

open access: yes, 1981
Fluid fertilizers are available in a wide range of products to Kentucky farmers. Although the term liquid fertilizer is commonly used to describe all fluid fertilizers, in reality the two terms do not imply the exact same meaning.
