Cell type-specific genomic regulation is driven by the binding of transcription factors (TFs) in accessible genomic regions.Thus,chromatin accessibility can be used to identify cis-regulatory ele-ments and directly depict cellular identity.Single-cell Assay for Transposase-Accessible Chromatin using sequencing (Single-cell ATAC-seq or scATAC-seq) has enabled genome-wide profiling of chromatin accessibility at single-cell resolution and can thus reveal epigenetic heterogeneity at cellular level [1].

Uranium extraction from seawater is of strategic significance for nuclear power generation.Amidoxime-based functional adsorbents play indispensable roles in the recovery of seawater uranium with high effi-ciency.Nevertheless,balancing the adsorption capac
The stability of perovskite solar cells is an important issue to be addressed for future applications.Perovskite solar cells are vulnerable to exposure to UV light due to promoted chemical reactions.However,preventing UV light from entering solar cells lo
CD1d-restricted natural killer T (NKT) cells are innate-like T lymphocytes with protective or pathogenic roles in the development of influenza pneumonia.Here,we show that lung-infiltrated and activated NKT cells are the major cellular source of LIGHT/TNFS
Perovskite light-emitting diodes (PeLEDs) have been considered to be the most promising candidate for solid-state lighting and high-definition full-color display due to their attractive properties such as tunable emission wavelengths,narrow full width at
