As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

In a recent paper published in cell,Xia et al.1 carried out 3D reconstructions of Blue Tongue Virus(BTV)particles and their assembly intermediates using a combination of cellular cryo-electron tomography(cryo-ET)and single-particle cryo-electron microscopy(cryo-EM).They were able to identify 11 structures,allowing them to refine our understanding of how double-stranded ribonucleic acid(dsRNA)viruses replicate in cells.

Sperm function testing, once commonly performed for the infertile couple before employing assisted reproductive technology （ART）, has fallen out of favour in many reproductive medicine centers throughout the world. Indeed, the most recent addition of the ＇World Health Organisation （WHO） Laboratory Manual for the Examination and Processing of Hu- man Semen＇ now groups many of these procedures into a section termed Research Procedures. In large part, this reflects the current clinical practice of bypassing the in-depth evaluation of the male partner, while assuming that if a spermatozoon can be found for intracytoplasmic sperm injection （IcSI）, it must be a healthy cell capable of achieving fertilization. Never- theless, sperm function testing can provide valuable clinical insights into defects causing male infertility. Admittedly, in some cases, functional sperm deficiencies can be overcome using an ART. In other cases, couples will be empowered by the knowledge of the cause of their infertility, and for some couples, perhaps even the likelihood of IcSI success （relative to the spermatozoa）. The knowledge allows them to make truly informed reproductive decisions, including （perhaps） the de- cision to seek donor insemination, to adopt or to remain childless. Knowledge of the cause of their infertility may provide closure for couples and a sense of confidence regarding their choice of reproductive treatment.

近几十年来，由于道路网络的扩张和城市化的蓬勃发展，道路建设对典型草原的影响引起了广泛的关注。然而，道路类型和距离对植物种群生长的综合影响仍然知之甚少。因此，本研究以陇东黄土高原微温微干典型草原为研究对象，探讨了道路建设（道路类型、距离）对菊科优势种茵陈蒿（Artemisia capillaris）和伴生种阿尔泰狗娃花（Aster altaicus）生长繁殖影响的驱动因素及其作用机制。结果表明，道路建设促进茵陈蒿的横向生长和无性繁殖，促进阿尔泰狗娃花的垂直生长和有性繁殖。阿尔泰狗娃花具有更强的更新潜力。普通公路茵陈蒿和阿尔泰狗娃花的地上生物量分别比其它两种道路平均高49%和27%，因此其对普通公路建设的响应更加敏感。此外，道路建设主要通过影响土壤进一步影响两个种群的地上生物量在群落中的占比。阿尔泰狗娃花的地上生物量及其在群落中的占比在距离20—35 m的范围存在明显阈值。因此需要注意将此范围内的植被保护和恢复措施与道路管理动态结合，影响植物生长繁殖，调控群落构建过程，以应对道路建设对种群和群落关系扰动的巨大挑战。
