Theodore Savage
Authors: Hamilton Cicely 
Published: February 2023

From one of the earliest feminist science fiction writers, a novel that envisions the fall of civilization—and the plight of the modern woman in a post-apocalyptic wilderness.
When war breaks out in Europe, British civilization collapses overnight. The ironically named protagonist must learn to survive by his wits in a new Britain. When we first meet Theodore Savage, he is a complacent civil servant, primarily concerned with romancing his girlfriend. During a brief war in which both sides use population displacement as a terrible strategic weapon, Savage must battle his fellow countrymen. He shacks up with an ignorant young woman in a forest hut—a kind of inverse Garden of Eden, where no one is happy. Eventually, he sets off in search of other survivors . . . only to discover a primitive society where science and technology have come to be regarded with superstitious awe and terror. A pioneering feminist, Hamilton offers a warning about the degraded state of modern women, who—being “unhandy, unresourceful, superficial”—would suffer a particularly sad fate in a postapocalyptic social order.

Published: February 2023

Oceanic heatwaves have significant impacts on disease dynamics in marine ecosystems. Following an extreme heatwave in Nanoose Bay, British Columbia, Canada, a severe sea cucumber wasting event occurred that resulted in the mass mortality of Apostichopus californicus. Here, we sought to determine if heat stress in isolation could trigger wasting symptoms in A. californicus. We exposed sea cucumbers to (i) a simulated marine heatwave (22 °C), (ii) an elevated temperature treatment (17 °C), or (iii) control conditions (12 °C). We measured the presence of skin lesions, mortality, posture maintenance, antipredator defences, spawning, and organ evisceration during the 79-hour thermal exposure, as well as 7-days post-exposure. Both the 22 °C and 17 °C treatments elicited stress responses where individuals exhibited a reduced ability to maintain posture and an increase in stress spawning. The 22 °C heatwave was particularly stressful, as it was the only treatment where mortality was observed. However, none of the treatments induced wasting symptoms as observed in the Nanoose Bay event. This study provides evidence that sea cucumber wasting may not be triggered by heat stress in isolation, leaving the cause of the mass mortality event observed in Nanoose unknown.

Influence of Lead on Morphology and Genetic Composition of Pleurotus tuber-regium
Authors: Iruoma Anyakorah Caroline , Hussein Tiamiyu 
Published: February 2023

Aims: Lead is a heavy metal pollutant that persists in the environment, has no biological function, and is potentially toxic to microorganisms. The study examined the effect of lead on the morphology and genetic profile of Pleurotus tuber-regium, an edible mushroom.
Study Design: Experimental study design.
Place and Duration of Study: Bells University of Technology between December 2017 and August 2018.
Methodology: P. tuber-regium sclerotium was planted in loamy soils polluted with PbO (50, 80, and 100 mg/kg). The effect of the lead was assessed by recording time for mushroom emergence, fresh fruitbody weight, stipe and pileus diameter, % protein, %ash, and molecular profile of mushrooms harvested from polluted soils against a control. Extracted DNA was amplified with ITS1 and ITS4 universal primers; amplicons were visualized with a UV Bio-Rad illuminator.
Results: Lead had varied influences on the morphometry. The fruitbody emergence was fastest in polluted soils and significantly different from the control. Fruiting occurred after 13.23±0.76, 5.41±0.88, 9.33±0.75 and 11.01±1.06 days in 0, 50, 80 and 100 mg/kg Pb polluted soils respectively. The fresh weight, stipe, and pileus diameter were significantly different at 50 mg/kg compared to the control. The range in values was 8.57±0.75 – 15.21±0.85g, 9.30±0.89 - 14.40±0.99mm, and 3.33±0.75 - 9.60±0.57cm respectively. The %protein and %ash contents were higher in mushrooms from polluted soils. Lead accumulated in polluted soils but the bioaccumulation coefficient was low. DNA profile showed variations in amplicon sizes.
Conclusion: The study revealed that continuous exposure of Pleurotus tuber-regium to lead caused varied morphological and genetic changes. It led to increased fresh weight, stipe diameter, pileus diameter, and variation in DNA amplicons. The implication is that lead could cause variations in the morphology and genetic composition of P. tuber-regium.

Shifting baselines for species in chronic decline and assessment of conservation status. Are hazel dormiceMuscardinus avellanariusEndangered?

AbstractLong‐term data are beneficial for monitoring the conservation status of species. Assessments of population change over recent periods of fixed duration will, however, be subject to ‘shifting baselines’, where the accepted norm for the population at the start of the period already represents a reduction from historical levels. International Union for Conservation of Nature Red List criteria for categorizing conservation threat rely on assessing declines against quantitative thresholds, generally measured over 10 years, as indications of the likelihood of extinction in the near future. By contrast, legal frameworks such as the European Habitats Directive require states to achieve and sustain ‘Favourable Conservation Status’ for protected species, while domestic conservation legislation can have more diverse objectives and mechanisms, based on local contexts that extend beyond biological or quantitative criteria.We explore the challenges associated with assessing the risk of extinction and the conservation status that arise from the availability of long‐term monitoring data for hazel dormiceMuscardinus avellanariusin the United Kingdom.Numbers of adult dormice counted in the National Dormouse Monitoring Programme are in ongoing decline, amounting to an overall decline of 78% (95% confidence interval = 72%–84%) over 27 years, 1994–2020. If the observed annual rate of decline of 5.7% (95% CI = 4.7%–6.8%) were to continue unabated, dormouse counts would decline by >90% from 1994 to 2034. Despite this, the species would never be categorized as Endangered, under IUCN criteria, which specify a reduction of >50% within 10 years.While such chronic decline may not indicate imminent risk of extinction, justifying a higher Red List category, it is a demonstration of unfavourable conservation status at a national scale. Prioritization based on demonstration of such chronic declines might direct more effective action towards species conservation at a point when their recovery is more attainable, rather than attempting later to reverse a journey to the brink of extinction when the species is finally ‘Endangered’.

AbstractThe lattice thermal conductivity (κph) of metals and semimetals is limited by phonon‐phonon scattering at high temperatures and by electron‐phonon scattering at low temperatures or in some systems with weak phonon‐phonon scattering. Following the demonstration of a phonon band engineering approach to achieve an unusually high κph in semiconducting cubic‐boron arsenide (c‐BAs), recent theories have predicted ultrahigh κph of the semimetal tantalum nitride in the θ‐phase (θ‐TaN) with hexagonal tungsten carbide (WC) structure due to the combination of a small electron density of states near the Fermi level and a large phonon band gap, which suppress electron‐phonon and three‐phonon scattering, respectively. Here, measurements on the thermal and electrical transport properties of polycrystalline θ‐TaN converted from the ε phase via high‐pressure synthesis are reported. The measured thermal conductivity of the θ‐TaN samples shows weak temperature dependence above 200 K and reaches up to 90 Wm−1K−1, one order of magnitude higher than values reported for polycrystalline ε‐TaN and δ‐TaN thin films. These results agree with theoretical calculations that account for phonon scattering by 100 nm‐level grains and suggest κph increase above the 249 Wm−1 K−1 value predicted for single‐crystal WC when the grain size of θ‐TaN is increased above 400 nm.
Confined Diffusion Strategy for Customizing Magnetic Coupling Spaces to Enhance Low‐frequency Electromagnetic Wave Absorption
Authors: Rao Longjun , Wang Lei , Yang Chendi , Zhang Ruixuan , Zhang Jincang , Liang Chongyun , Che Renchao 
Published: February 2023

AbstractThe rational design of magnetic composites has great potential for electromagnetic (EM) absorption, particularly in the low‐frequency range of 2–8 GHz. However, the scalable synthesis of such magnetic absorbers with both high magnetic content and good dispersity remains challenging. In this study, a confined diffusion strategy is proposed to fabricate functional magnetic‐carbon hollow microspheres. Driven by the ferromagnetic enhanced Kirkendall diffusion effect, the in situ alloying of FeCo nanoparticles is tightly confined in carbon shells, effectively inhibiting magnetic agglomeration. Moreover, the core–shell FeCo–carbon nano‐units further assemble into dispersive microscale magnetic‐carbon Janus bulges on both the inner and outer surfaces of the hollow microsphere. The optimized hollow FeCo@C microspheres exhibit excellent low‐frequency EM wave absorption performance: the minimum reflection loss (RLmin) is −35.9 dB, and the absorption bandwidth covers almost the entire C‐band. Systematic investigation reveals that the large size of the magnetic‐carbon integration, high–density confined magnetic units, and strong magnetic coupling are essential for enhancing the magnetic loss dissipation of low‐frequency EM waves. This study provides a novel strategy for fabricating advanced EM wave absorbers and significant inspiration for investigating the magnetic attenuation mechanism at low frequency.

Published: February 2023

AbstractComposite polymer electrolytes (CSEs) that simultaneously possess superior electrochemical performances with robust mechanical properties are highly desired to the application of high‐energy lithium metal batteries. Herein, a novel dual‐polymer@inorganic network CSE (DNSE@IN) through a sequential nonhydrolytic sol‐gel reaction of tetraethoxysilane (TEOS) and the semi‐interpenetration of poly(vinylidene fluoride‐co‐hexafluoropropene)‐hexafluoropropylene (P(VDF‐HFP)) with poly(ionic liquid) (PIL) is proposed. DNSE@IN, which has a robust dual‐polymer@inorganic networks, not only has high ionic conductivity (0.53 mS cm−1 at 20 °C), but also exhibits an outstanding Young's modulus of 723.2 MPa. As a result, the DNSE@IN based Li/LiFePO4 and Li/Li1.17Ni0.27Co0.05Mn0.52O2 (Li‐rich) cells exhibit remarkable cycling stability from room temperature (RT) to 100 °C. As‐assembled Li/Li‐rich battery shows superior cyclability of 194.3 mAh g−1 after 70 cycles at 4.3 V under RT. Additionally, the scale‐up high‐voltage Li/Li‐rich pouch cells exhibit excellent cyclability (nearly 100% capacity retention after 93 cycles) and superior flexibility, safety at RT for potential practical applications. As such, the work of decoupling ionic conductivity and mechanical properties opens a novel route to develop novel CSEs for the construction of high‐energy lithium metal batteries.

Published: February 2023

AbstractInterfacial engineering is a vital strategy to enable high‐performance perovskite solar cells (PSCs). To develop efficient, low‐cost, and green biomass interfacial materials, here, a bifunctional cellulose derivative is presented, 6‐O‐[4‐(9H‐carbazol‐9‐yl)butyl]‐2,3‐di‐O‐methyl cellulose (C‐Cz), with numerous methoxy groups on the backbone and redox‐active carbazole units as side chains. The bifunctional C‐Cz shows excellent energy level alignment, good thermal stability and strong interactions with the perovskite surface, all of which are critical for not only carrier transportation but also potential defects passivation. Consequently, with C‐Cz as the interfacial modifier, the PSCs achieve a remarkably enhanced power conversion efficiency (PCE) of 23.02%, along with significantly enhanced long‐term stability. These results underscore the advantages of bifunctional cellulose materials as interfacial layers with effective charge transport properties and strong passivation capability for efficient and stable PSCs.
