Genome expression and stability are dependent on biological processes that control repetitive DNA sequences and nuclear compartmentalization. The phase separation of macromolecules has recently emerged as a major player in the control of biological pathways. Here, we summarize recent studies that collectively reveal intersections between phase separation, repetitive DNA elements, and nuclear compartments. These intersections modulate fundamental processes, including gene expression, DNA repair, and cellular lifespan, in the context of health and diseases such as cancer and neurodegeneration.

This study developed a W/O/W emulsion gel encapsulating proanthocyanidins from Aronia melanocarpa (Michx.) Elliott (APC) using polyglycerol ricinoleate (PGPR) as the lipophilic emulsifier and sodium caseinate (NaCN)-alginate (Alg) as the hydrophilic emulsifier. The optimal preparation process was established based on particle size, zeta potential, phase separation, centrifugal stability, and microscopic morphology: 4.

The separation of xylene isomers is a critical and energy-intensive process in the petrochemical industry, primarily due to their closely similar molecular structures and boiling points. In this work, we report the synthesis and application of a novel core-shell zeolitic imidazolate framework (ZIF) composite, ZIF-65@ZIF-67, designed to significantly enhance the kinetic separation of xylene isomers through a synergistic "shell-gated diffusion and core-facilitated transport" strategy. The external ZIF-67 shell selectively restricts the diffusion of larger isomers (MX and OX), while the internal ZIF-65 core accelerates the diffusion of PX, thereby amplifying the diffusion differences among the isomers.

A novel pH-responsive full-bio-based surfactant (Ca-S) containing a dynamic covalent bond is synthesized using renewable cashew phenol, 5-chloro-2-furanaldehyde, and taurine. The structure of Ca-S is characterized by Fourier transform infrared spectroscopy (FTIR) and H nuclear magnetic resonance (NMR) analysis. Limonene containing oil-in-water (O/W) microemulsions are prepared on the basis of the Ca-S surfactant and are applied to the remediation of oil-contaminated soil under low-energy conditions at ambient temperature.

Many transcription factors (TFs) have been shown to bind to super-enhancers, forming transcriptional condensates to activate transcription in various cellular systems. However, the genomic and epigenomic determinants of phase-separated transcriptional condensate formation remain poorly understood. Questions regarding which TFs tend to associate with transcriptional condensates and what factors influence their association are largely unanswered.

Background: Incorporating β-carotene into food systems improves nutritional value by providing a natural source of vitamin A. However, maintaining its stability during processing and storage is a significant barrier for its bioavailability.
Results: This study investigated the utilization of banana rachis nanocellulose (BRNC) as a natural stabilizer in the formulation of Pickering nanoemulsion (PNE).
