Microalgae for bioremediation: advances, challenges, and public perception on genetic engineering.

The increase in the global population and industrial activities has led to an extensive use of water, the release of wastewater, and overall contamination of the environment. To address these issues, efficient treatment methods have been developed to decrease wastewater nutrient content and contaminants. Microalgae are a promising tool as a sustainable alternative to traditional wastewater treatment.

Odour impact simulation of a large urban wastewater treatment plant through the numerical solution of a Eulerian model.

This study aims to develop a solver to calculate the dispersion of emitted odour from the main sources located in a large urban wastewater treatment plant (WWTP). Its seasonal odour impact on surrounding areas, including nearby populations, was also evaluated. Different seasons of the year were studied using the prevailing meteorological conditions in each case, within the framework of a Eulerian model.

The African introgression of Murciano Granadina goats has a Moroccan origin and displays remarkable levels of inter-individual variability.

There is evidence that Murciano Granadina (MG), the most important caprine dairy breed in Spain, has been introgressed by African goats, but the precise geographic origin of such introgression has not been identified yet. Moreover, an accurate estimate of the magnitude of this African introgression is lacking, since current estimates are based on small numbers of sampled individuals. The aim of our work was to tackle these two issues by genotyping 500 MG goats with the Goat SNP50 BeadChip and comparing their genotypes with those of reference populations from Spain (Bermeya), France (Saanen), Morocco (Barcha, Draa, Ghazalia, Noire de Atlas, Nord, Moroccan), Egypt (Barki, Oasis, Saidi), Algeria (Arabia, Makatia, M'Zabite, Kabyle), Tunisia (Tunisian native breeds) and Sudan (Desert, Nilotic, Taggar).

Bioavailability of flumequine and diclofenac in mice exposed to a metal-drug chemical cocktail. Evaluation of the protective role of selenium.

Background And Purpose: Organisms, including humans, are subjected to the simultaneous action of a wide variety of pollutants, the effects of which should not be considered in isolation, as many synergies and antagonisms have been found between many of them. Therefore, this work proposes an in vivo study to evaluate the effect of certain metal contaminants on the bioavailability and metabolism of pharmacologically active compounds. Because the most frequent entry vector is through ingestion, the influence of the gut microbiota and the possible protective effects of selenium has been additionally evaluated.

Integral evaluation of effective conversion of sewage sludge from WWTP into highly porous activated carbon.

Urban sewage sludge (SL) is a major concern due to the number of environmental problems it causes. Its application for different purposes is strictly regulated, limiting the possibilities of recycling and reusing this material.

Modeling transposable elements dynamics during polyploidization in plants.

In this work we study the proliferation of transposable elements (TEs) and the epigenetic response of plants during the process of polyploidization. Through a deterministic model, expanding on our previous work on TE proliferation under epigenetic regulation, we study the long-term TE distribution and TE stability in the subgenomes of both autopolyploids and allopolyploids. We also explore different small-interfering RNA (siRNA) action modes on the subgenomes, including a model where siRNAs are not directed to specific genomes and one where siRNAs are directed - i.

Understanding Bridging Sites and Accelerating Quantum Efficiency for Photocatalytic CO Reduction.

We report a novel double-shelled nanoboxes photocatalyst architecture with tailored interfaces that accelerate quantum efficiency for photocatalytic CO reduction reaction (CORR) via Mo-S bridging bonds sites in S-InS@2H-MoTe. The X-ray absorption near-edge structure shows that the formation of S-InS@2H-MoTe adjusts the coordination environment via interface engineering and forms Mo-S polarized sites at the interface. The interfacial dynamics and catalytic behavior are clearly revealed by ultrafast femtosecond transient absorption, time-resolved, and in situ diffuse reflectance-Infrared Fourier transform spectroscopy.

Mechanics Predicts Effective Critical-Size Bone Regeneration Using 3D-Printed Bioceramic Scaffolds.

Background: 3D-printed bioceramic scaffolds have gained popularity due to their controlled microarchitecture and their proven biocompatibility. However, their high brittleness makes their surgical implementation complex for weight-bearing bone treatments. Thus, they would require difficult-to-instrument rigid internal fixations that limit a rigorous evaluation of the regeneration progress through the analysis of mechanic-structural parameters.

To Mob or Not to Mob: Habitat and Time of Day Influence in Mobbing Behavior in the Azure-Winged Magpie ().

While mobbing, individuals utter distinctive calls and perform visual threatening displays. Like any other antipredatory strategies, it involves some costs (time, energy, injuries, and even death). Therefore, mobbing would be expected to vary depending on the perceived magnitude of the predation risk.

Use of granules and free salts for Fe and Zn fortification of leafy vegetables: Improvements in trace element bioaccessibility and fulfillment of Dietary Reference Intakes.
