Abstract ) organic conductors. Few n‐type polymers with only short‐range lamellar stacking for high‐conductivity materials have been reported. Here, we describe an n‐type short‐range lamellar‐stacked all‐polymer thermoelectric system with highest of 78 S−1, power factor ( PF ) of 163 μW m−1 K−2, and maximum Figure of merit (ZT ) of 0.53 at room temperature with a dopant/host ratio of 75 wt%. The minor effect of polymer dopant on the molecular arrangement of conjugated polymer PDPIN at high ratios, high doping capability, high Seebeck coefficient (S ) absolute values relative to, and atypical decreased thermal conductivity ( ) with increased doping ratio contribute to the promising performance. -

Abstract The effects of nutrient pollution on coral reef ecosystems are multifaceted. Numerous experiments have sought to identify the physiological effects of nutrient enrichment on reef‐building corals, but the results have been variable and sensitive to choices of nutrient quantity, chemical composition and exposure duration.
To test the effects of chronic, ecologically relevant nutrient enrichment on coral growth and photophysiology, we conducted a 5‐week continuous dosing experiment on two Hawaiian coral species,
Porites compressa andPocillopora acuta . We acclimated coral fragments to five nutrient concentrations (0.1–7 µMand 0.06–2.24 µM ) with constant stoichiometry 2.5:1 nitrate to phosphate) bracketing in situ observations from reefs throughout the Pacific. Nutrient enrichment linearly increased photophysiological performance of both species within 3 weeks. The effect of nutrients on
P. acuta photochemical efficiency increased through time while a consistent response inP. compressa indicated acclimation to elevated nutrients within 5 weeks. Endosymbiont densities and total chlorophyll concentrations also increased proportionally with nutrient enrichment inP. acuta , but not inP. compressa , revealing contrasting patterns of host–symbiont acclimatization.The two species also exhibited contrasting effects of nutrient enrichment on skeletal growth. Calcification was enhanced at low nutrient enrichment (1 µM
) in P. acuta , but comparable to the control at higher concentrations, whereas calcification was reduced inP. compressa (30%–35%) above 3 µM. Stable isotope analysis revealed species‐specific nitrogen uptake dynamics in the coral–algal symbiosis. The endosymbionts of
P. acuta exhibited increased nitrogen uptake (decreased δ15N) and incorporation (19%–31% decrease in C:N ratios) across treatments. In contrast,P. compressa endosymbionts maintained constant δ15N values and low levels of nitrogen incorporation (9%–11% decrease in C:N ratios). The inability ofP. acuta to regulate endosymbiont nutrient uptake may indicate an emerging destabilization in the coral–algal symbiosis under nutrient enrichment that could compromise resistance to additional environmental stressors.Our results highlight species‐specific differences in the coral–algal symbiosis, which influence responses to chronic nutrient enrichment. These findings showcase how symbioses can vary among closely related taxa and underscore the importance of considering how life‐history traits modify species response to environmental change.

Abstract Motivated by its potential use as a starting point for solving various cosmological constant problems, we study F‐theory compactified on the warped product
where Y 8is amanifold, and the S 3factor is the target space of anWess–Zumino–Witten (WZW) model at level N . Reduction to M‐theory exploits the abelian duality of this WZW model to anorbifold. In the large N limit, the untwisted sector is captured by 11D supergravity. The local dynamics of intersecting 7‐branes in thegeometry is controlled by a Donaldson–Witten twisted gauge theory coupled to defects. At late times, the system is governed by a 1D quantum mechanics system with a ground state annihilated by two real supercharges, which in four dimensions would appear as “ supersymmetry” on a curved background. This leads to a cancellation of zero point energies in the 4D field theory but a split mass spectrum for superpartners of order specified by the IR and UV cutoffs of the model. This is suggestively close to the TeV scale in some scenarios. The classical 4D geometry has an intrinsic instability which can produce either a collapsing or expanding Universe, the latter providing a promising starting point for a number of cosmological scenarios. The resulting 1D quantum mechanics in the time direction also provides an appealing starting point for a more detailed study of quantum cosmology. -
The effect of lifelong endurance exercise on cardiovascular structure and exercise function in womenmore » « less
Key points The beneficial effects of sustained or lifelong (>25 years) endurance exercise on cardiovascular structure and exercise function have been largely established in men.
The current findings indicate that committed (≥4 weekly exercise sessions) lifelong exercise results in substantial benefits in exercise capacity (
), cardiovascular function at submaximal and maximal exercise, left ventricular mass and compliance, and blood volume compared to similarly aged or even younger (middle‐age) untrained women. Endurance exercise training should be considered a key strategy to prevent cardiovascular disease with ageing in women as well as men.
Abstract This study was a retrospective, cross‐sectional analysis of exercise performance and left ventricular (LV) morphology in 70 women to examine whether women who have performed regular, lifelong endurance exercise acquire the same beneficial adaptations in cardiovascular structure and function and exercise performance that have been reported previously in men. Three groups of women were examined: (1) 35 older (>60 years) untrained women (older untrained, OU), (2) 13 older women who had consistently performed four or more endurance exercise sessions weekly for at least 25 years (older trained, OT), and (3) 22 middle‐aged (range 35–59 years) untrained women (middle‐aged untrained, MU) as a reference control for the appropriate age‐related changes. Oxygen uptake (
) and cardiovascular function (cardiac output ( ); stroke volume (SV) acetylene rebreathing) were examined at rest, steady‐state submaximal exercise and maximal exercise (maximal oxygen uptake, ). Blood volume (CO rebreathing) and LV mass (cardiac magnetic resonance imaging), plus invasive measures of static and dynamic chamber compliance were also examined. ( p < 0.001) and maximal exerciseand SV were larger in older trained women compared to the two untrained groups (∼17% and ∼27% for and SV, respectively, versus MU; ∼40% and ∼38%versus OU, allp < 0.001). Blood volume (mL kg−1) and LV mass index (g m−2) were larger in OTversus OU (∼11% and ∼16%, respectively, bothP ≤ 0.015) Static LV chamber compliance was greater in OT compared to both untrained groups (median (25–75%): MU: 0.065 (0.049–0.080); OU: 0.085 (0.061–0.138); OT: 0.047 (0.031–0.054),P ≤ 0.053). Collectively, these findings indicate that lifetime endurance exercise appears to be extremely effective at preserving or even enhancing cardiovascular structure and function with advanced age in women. -

Abstract Synthesis gas (syngas) fermentation via the Wood–Ljungdahl pathway is receiving growing attention as a possible platform for the fixation of
and renewable production of fuels and chemicals. However, the pathway operates near the thermodynamic limit of life, resulting in minimal adenosine triphosphate (ATP) production and long doubling times. This calls into question the feasibility of producing high‐energy compounds at industrially relevant levels. In this study, we investigated the possibility of co‐utilizing nitrate as an inexpensive additional electron acceptor to enhance ATP production during ‐dependent growth of Clostridium ljungdahlii ,Moorella thermoacetica , andAcetobacterium woodii . In contrast to other acetogens tested, growth rate and final biomass titer were improved forC. ljungdahlii growing on a mixture ofand when supplemented with nitrate. Transcriptomic analysis, labeling, and an electron balance were used to understand how electron flux was partitioned between and nitrate. We further show that, with nitrate supplementation, the ATP/adenosine diphosphate (ADP) ratio and acetyl‐CoA pools were increased by fivefold and threefold, respectively, suggesting that this strategy could be useful for the production of ATP‐intensive heterologous products from acetyl‐CoA. Finally, we propose a pathway for enhanced ATP production from nitrate and use this as a basis to calculate theoretical yields for a variety of products. This study demonstrates a viable strategy for the decoupling of ATP production from carbon dioxide fixation, which will serve to significantly improve the fixation rate and the production metrics of other chemicals from and in this host.
