UV light activation of peracetic acid: new insights into radical generation based on excited states
Science China PressPeer-Reviewed Publication
A recent study has used advanced techniques to uncover the role of ultraviolet (UV) light in activating peracetic acid (PAA) to generate powerful radicals, essential for water treatment. By combining in-situ electron paramagnetic resonance (EPR) with density functional theory (DFT) calculation, the researchers identified and analyzed the types and concentrations of radicals produced under different UV wavelengths (185, 254, and 365 nm). The results show that UV light at different wavelengths influences the type and concentration of formed radicals. The study provides new insights into how PAA-based advanced oxidation processes (AOPs) work based on the key radicals identification, offering a solid foundation for optimizing UV-based water purification technologies and potentially expanding their application in environmental remediation areas.

NAT10 primes a post-transcriptional repertoire essential for the maintenance of spermatogonial homeostasis
Science China PressPeer-Reviewed Publication
In a paper published in Science Bulletin, a Chinese team of scientists led by Professor Bao revealed that the N-acetyltransferase 10 (NAT10), a ‘writer’ of the N4-acetylcytidine (ac4C) mark, is essential for spermatogonial proliferation and differentiation throughout first-wave spermatogenesis and during steady-state spermatogenesis in mice. Importantly, they identify PRRC2B as an intimate Nat10 partner that potentially assists the deposition or reading of the ac4C mark in mRNAs. Collectively, this study reinforces the importance of gene expression regulation at the epitranscriptomic level in both the germline and soma cells.

Abrupt lateral beam shifts from terahertz quasi-bound states in the continuum
Science China PressPeer-Reviewed Publication
In a paper published in Science Bulletin, an international team of physicists from Singapore and China demonstrates how quasi-bound states in the continuum (QBICs) can induce abrupt lateral beam shifts in the terahertz regime. By applying Brillouin zone folding to a compound grating waveguide, the researchers created a QBIC band that enables sudden and significant beam shifts, offering new insights into real-space QBIC properties and potential applications in sensing and wavelength multiplexing.

20 nM Pladienolide B +6 h treatment = totipotent stem cells? The new method captures totipotency
Science China PressPeer-Reviewed Publication
Researchers from Nanjing Medical University have developed a novel method to generate transient totipotent blastomere-like stem cells (tTBLCs) by treating mouse embryonic stem cells (mESCs) with a short-term high-dose of the splicing inhibitor Pladienolide B (PlaB). These tTBLCs can self-organize into blastocyst-like structures (blastoids) and recapitulate key pre-implantation developmental processes, offering a new tool for studying early embryogenesis and potential applications in drug screening.

Anthracycline-induced cardiotoxicity: emerging mechanisms and therapies
Science China PressPeer-Reviewed Publication
In recent years, chemotherapy-induced cardiovascular disease has emerged as a significant cause of mortality among cancer survivors. Anthracyclines, pivotal in treating cancers like breast cancer and leukemia, are indispensable in cancer therapy, yet their severe cardiotoxicity presents a formidable challenge. A recent review in Medicine Plus offers profound insights into anthracycline-induced cardiotoxicity (AIC), exploring its mechanisms and therapeutic strategies, contributing to safer oncological treatments in the future.

Non-coordinating charge transfer accelerates Zn2+ desolvation in OHL for stable aqueous Zn batteries
Science China PressPeer-Reviewed Publication
The formation of a strong coordination structure, [Zn(H2O)6]2+ often increases direct contact between the solvated H2O and Zn anodes on the inner Helmholtz layer, which exacerbates undesirable side reactions and dendrite growth, hindering the practical application of aqueous Zn metal batteries. Researchers identify that the solvated H2O can be effectively minimized by an artificial solid electrolyte interphase (SEI) consisting of highly nitrogen-doped amorphous carbon (NC) and perfluorosulfonic acid polymer (Nafion). Theoretical and experimental analyses reveal that NC raises the Fermi level of the composite SEI and activates the non-coordinating charge transfer from the SEI to [Zn(H2O)6]2+, which leads to ultrafast desolvation of hydrated Zn-ions in the outer Helmholtz layer; while the Nafion framework ensures selective transport channels for Zn ions. Remarkably, the derived NC-Nafion@Zn symmetric cell exhibits a long lifespan (3400 h, 1 mA cm-2; 2000 h, 5 mA cm-2); moreover, the NC-Nafion@Zn//Mn4O3-carbon nanotubes full battery delivers ultralong cycling stability of 9300 cycles at 2 A g-1 with a high retention of 91.3%.
