In this study, we present the synthesis, characterization, and structural analysis of a novel zeolite, ITQ-70, using 3D electron diffraction. This unique material was synthesized under alkaline conditions, employing tetrakis(diethylamino)phosphonium as an organic structure-directing agent, leading to the formation of a pure silica zeolite. ITQ-70 is distinguished by its extra-large pore apertures, which extend along all three axes and intersect one to the other.

However, strategies aimed at extending the lifetime of batteries are not yet sufficiently considered within the European battery industry, particularly regarding repurposing. Using second-life lithium-ion batteries (SLBs) before subsequent recycling can offer several advantages, such as the development of sustainable business models, the reduction of emissions, and alignment with UN Sustainable Development Goals 7, 12, and 13.

- The research investigates how variations in microbial communities in seasonally flooded forests are influenced not just by environmental factors, but also by plant traits.
- Two null models were used to analyze microbial communities from 72 seedlings of seven tropical tree species in French Guiana, revealing the dominance of stochastic processes in community assembly, with differences observed between fungi and bacteria.
- The study emphasizes the importance of understanding tree species and their associated microbial communities to better inform adaptation strategies in the context of climate change, suggesting further exploration of additional plant traits.
Background: Recessive deleterious variants are known to segregate in livestock populations, as in humans, and some may be lethal in the homozygous state.
Results: We used phased 50 k single nucleotide polymorphism (SNP) genotypes and pedigree data to scan the genome of 6845 Manech Tête Rousse dairy sheep to search for deficiency in homozygous haplotypes (DHH). Five Manech Tête Rousse deficient homozygous haplotypes (MTRDHH1 to 5) were identified, with a homozygous deficiency ranging from 84 to 100%.
Article Synopsis
- Chromosomal inversions contribute to genetic diversity and reproductive isolation between evolutionary lineages, impacting speciation.
- In studying the long-snouted seahorse, researchers identified two significant chromosomal inversions that vary in frequency among different geographic lineages and ecotypes.
- These inversions are suggested to be ancient polymorphisms with one maintained through divergent selection and the other through pseudo-overdominance, revealing complex interactions influencing reproductive traits and evolutionary dynamics.
