The microstructural analysis of muds and mudrocks requires very high-resolution measurement. Recent advances in electron microscopy have contributed significantly to the improved characterisation of mudrock microstructures and their consequent petrophysical properties. However, imaging through electron microscopy is limited to small areas of coverage such that upscaling of these properties is a great challenge. In this paper, we develop a new methodology for multiple large-area imaging using scanning electron microscopy through automated acquisition and stitching from polished thin-sections and ion-milled samples. The process is fast, efficient and minimises user-input and bias. It can provide reliable, quantifiable data on sediment grain size, grain orientation, pore size and porosity. Limitations include the time involved for individual runs and manual segmentation, the large amount of computer memory required, and instrument resolution at the nano-scale. This method is applied to selected samples of Quaternary muddy sediments from the Iberian margin at IODP Site 1385. The section comprises finegrained(very fine clayey silts), mixed-composition, biogenic-terrigenous hemipelagites, with a pronounced but non-regular colour cyclicity. There is a multi-tiered and diverse trace fossil assemblage of the deep-water Zoophycos ichnofacies. The sediment microstructures show small-scale heterogeneity in all properties, and an overall random fabric with secondary preferred grain-alignment. These results on the fabric differ, in part, from previous studies of hemipelagic muds. Further work is underway on their comparison with other deep-water sediment facies.

Similar to the phenomenon of knotted ropes in life, knotted climbing ropes will reduce their strength due to knots. Although computer simulations [1], theoretical speculation[2,3], and intuition [3] suggest that similar processes may occur at the nanoscale, this hypothesis has not been experimentally proven before. with the increasing maturity of molecular recognition and self-assembly, a research communication by Leigh et al. [4] published in Nature Chemistry introduced a molecular overhand knot into a polymer to study its effect on the scission rate of the polymer chain under tension.

Antimicrobial resistance (AMR) has been declared a major threat to global health, with the potential to reverse advances in treating disease, and impeding other global pri-orities including human development. The urgent menace of AMR has been recognized by the world Health Organi-sation Global Action Plan in 2015 [1], the 2016 United Nations General Assembly unanimous commitment to tackle AMR [2], and the Association of Southeast Asian Nations (ASEAN) 2017 declaration on AMR (3)AMR has been highlighted as a major health and economic challenge, with the consequences of failing to meet that challenge falling upon our children and grandchildren. Not only will children bear the burden of rising AMR, they are especially at risk now due to a number of factors. In many studies, children and the elderly are the highest consumers of antimicrobi-als (4)In addition, frequently inappropriate doses in chil-dren mean that they are receiving sub-therapeutic doses, maximizing the chance of encouraging resistant organ-isms to flourish. The normal behaviour of early childhood also encourages the spread of resistant organisms between children. Finally, their lifetime risk of exposure to resistant organisms is higher than adults.

CD8^(+) cytotoxic T cells(CTLs)protect against pathogens and cancer.1,2,3,4 Over the past few years,CTL responses have been extensively studied.1,2,3,4 In response to an infection,the CTL response develops in three phases:expansion,contraction,and memory.2,3,In the expansion phase,pathogen-derived antigens(Ags)trigger activation and proliferation of Ag-specific CTLs,leading to the generation of effector CTLs(eCTLs)with cytotoxic functions.2,5,Later,in the contraction phase,90–95%of eCTLs die as a result of activation-induced cell apoptosis.
