The cement industry is one of the major sources of greenhouse gas. Replacing cement with alternative materials such as incinerated sugarcane press mud (IWFC) is promising for reducing CO 2 emissions, but the quality of materials is diminished. This research then aims to investigate the influence of bioadmixture, calcifying bacteria Lysinibacillus sp. WH, at three bacterial dosage concentrations (10 8 , 10 9 , and 10 10 CFU/mL) on microstructural development and mechanical enhancement of Portland cement paste and cement pastes containing varied ratios of IWFC. The results show that the bacterial concentration of 10 10 CFU/mL effectively enhances mechanical characteristics of IWFC-cement pastes, while lower concentration is more favorable to Portland cement paste (P). Here, we are the first to provide evidence that the properties of cement paste composites comparable to Portland cement paste can be achieved even when the IWFC is replaced with cement as high as 20 % by weight together with the incorporation of calcifying bacteria. Moreover, IWFC-cement pastes with high bacterial concentration of 10 10 CFU/mL exhibit the fastest self-healing ability within two weeks. The regained strength after healing is >85 % in all composite specimens. Overall, this work provides an effective method to develop durable and eco-friendly cement.

Task-free functional connectivity in animal models provides an experimental framework to examine connectivity phenomena under controlled conditions and allows for comparisons with data modalities collected under invasive or terminal procedures. Currently, animal acquisitions are performed with varying protocols and analyses that hamper result comparison and integration. Here we introduce StandardRat, a consensus rat functional magnetic resonance imaging acquisition protocol tested across 20 centers. To develop this protocol with optimized acquisition and processing parameters, we initially aggregated 65 functional imaging datasets acquired from rats across 46 centers. We developed a reproducible pipeline for analyzing rat data acquired with diverse protocols and determined experimental and processing parameters associated with the robust detection of functional connectivity across centers. We show that the standardized protocol enhances biologically plausible functional connectivity patterns relative to previous acquisitions. The protocol and processing pipeline described here is openly shared with the neuroimaging community to promote interoperability and cooperation toward tackling the most important challenges in neuroscience.

This study optimized the mixotrophic cultivation of Chlorella sp. G049 using hydroponic effluent to maximize biomass, lipid, and polyunsaturated fatty acid accumulation. Optimal conditions, identified through response surface methodology, included 20-hour light exposure, 60.03 µmol/m2/s light intensity, and supplementation with 7.21 g/L glucose and 14.22 mg/L indole-3-acetic acid. Under these conditions, Chlorella sp. G049 achieved 3.77 g/L dry cell weight, 23.78 % lipid content, and 27.78 % polyunsaturated fatty acid (PUFA). Nutrient removal efficiencies were 100 % for ammonium, 63.10 % for nitrate, 98.85 % for phosphate, and 71.30 % for chemical oxygen demand, with carbon dioxide fixation reaching 1.00 g/L/day. A sequential biorefinery approach enabled sustainable biomass valorization, with high polyunsaturated fatty acid content for biodiesel and protein extraction yielding an amino acid profile with notable antioxidant activity. The residual biomass served as a biofertilizer, enhancing soil quality and promoting plant growth in lettuce. These results highlight the potential of Chlorella sp. G049 for sustainable wastewater treatment, carbon sequestration, and multiproduct biorefinery applications. © 2025 The Author(s)

Streptomyces rochei 7434AN4 produces two structurally unrelated polyketide antibiotics, lankacidin (LC) and lankamycin (LM), and their biosynthesis is tightly controlled by 2,3-disubstituted butenolide-type signaling molecules SRB1 and SRB2. We here investigated the distribution of 2,3-disubstituted butenolides (SRB-type butenolides) among randomly selected 122 Streptomyces strains using two approaches; (1) feeding of their culture extracts into an srrX-deficient strain KA20 of S. rochei, and (2) co-fermentation with strain KA20. All the randomly selected donor strains, except for Streptomyces cellostaticus (a LC and LM producer), failed to restore LC and LM production in strain KA20. These findings strongly revealed the rare distribution of SRB-type butenolide molecules in Streptomyces species. One of the SRB-type butenolide, SAB1, an inducing molecule for nikkomycin production in Streptomyces ansochromogenes, was unable to restore antibiotic production in strain KA20 even at 1 mM concentration. Furthermore, we noticed the accumulation of 4-dehydroxy-SRB1 as a novel compound when SRB1 was fed into strain KA20. Purified 4-dehydroxy-SRB1 has no inducing activity of antibiotic production in strain KA20 even at 1000-fold higher concentration (50 µM) against a minimum inducing concentration of natural SRB1 (40 nM). These findings suggested the importance of the length of a hydrocarbon chain attached at C-2 and a hydroxyl group at C-4 for inducing activity in S. rochei.

The "neutron lifetime puzzle" arises from the discrepancy between neutron lifetime measurements obtained using the beam method, which measures decay products, and the bottle method, which measures the disappearance of neutrons. To resolve this puzzle, we conducted an experiment using a pulsed cold neutron beam at J-PARC. In this experiment, the neutron lifetime is determined from the ratio of neutron decay counts to 3He(n,p)3H reactions in a gas detector. This experiment belongs to the beam method but differs from previous experiments that measured protons, as it instead detects electrons, enabling measurements with distinct systematic uncertainties. By enlarging the beam transport system and reducing systematic uncertainties, we achieved a fivefold improvement in precision. Analysis of all acquired data yielded a neutron lifetime of τn = 877.2 ± 1.7(stat.)+4−306(sys.) s. This result is consistent with bottle method measurements but exhibits a 2.3σ tension with the average value obtained from the proton-detection-based beam method. © 2024, CC BY.

BACKGROUND:Maternal infections are linked to neurodevelopmental impairments, highlighting the need to investigate SARS-CoV-2-induced immune activation. OBJECTIVE:This study aimed to evaluate the impact of maternal infection on neurodevelopment and investigate whether cytokine and chemokine profiles predict delays at 24 months. METHODS:Conducted in Brazil (January 2021-March 2022), this follow-up study included 18 SARS-CoV-2 positive pregnant women at 35-37 weeks' gestation, 15 umbilical cord blood samples, and blood samples from 15 children at 6 months and 14 at 24 months. Developmental delay was defined using the Bayley Scales of Infant and Toddler Development, Third Edition, with scores below 90 in cognitive, communication, or motor domains. RESULTS:At 6 months, 33.3% of infants exhibited cognitive delays, 20% communication delays, and 40% motor delays, increasing to 35.71%, 64.29%, and 57.14% at 24 months, respectively. Elevated interferon-gamma and tumor necrosis factor-alpha in cord blood correlated with cognitive delays, while interleukin (IL)-6, IL-8, IL-17, and IL-1β were associated with motor delays. Increased C-X-C motif chemokine ligand 10 and other cytokines were associated with communication delays. CONCLUSION:Maternal SARS-CoV-2 may impact infant neurodevelopment, as early cytokine elevations correlate with delays, highlighting the importance of early monitoring and interventions to reduce long-term effects. IMPACT:Prenatal SARS-COV-2 infection in pregnant women is linked to developmental delays in toddlers, with cytokine and chemokine changes associated with neurodevelopmental outcomes at 24 months. This study shows the long-term impact of maternal SARS-COV-2 infection on child development, highlighting inflammatory markers like IFN-γ, TNFα, IL-6, IL-8, IL-17, IL-1β, and CXCL10. Identifying specific cytokines correlating with cognitive, communication, and motor delays suggests potential biomarkers for early intervention. Conducted in Fortaleza, Brazil

This paper presents the fabrication and functional characterization of a novel chemiresistive sensor for room temperature ethanol vapors detection by means of sensing films consisting of oxidized single wall carbon nanohorn (ox-SWCNH) / tin dioxide (SnO 2 ) / polyvinylpyrrolidone (PVP) in the mass ratio equal to 1/1/1 and 2/1/1. These sensors with ox-SWCNH concentration higher than 33 wt%, which is much above percolation threshold in the composite (below 0.1 wt%), has shown unexpected high sensitivities for ethanol vapor concentrations in air in the range of 0.2-25 below 2 mg/L, as well as in the range of 2-25 mg/L. These sensors may be attractive for low power Internet of Things (IoT).

A total of 8218 pelagic microplastic samples from the world’s oceans were synthesized to create a dataset composed of raw, calibrated, processed, and gridded data which are made available to the public. The raw microplastic abundance data were obtained by different research projects using surface net tows or continuous seawater intake. Fibrous microplastics were removed from the calibrated dataset. Microplastic abundance which fluctuates due to vertical mixing under different oceanic conditions was standardized. An optimum interpolation method was used to create the gridded data;in total, there were 24.4 trillion pieces (8.2 × 10⁴ ~ 57.8 × 10⁴ tons) of microplastics in the world’s upper oceans. © The Author(s) 2021.
