Summary: Calcium phosphates (CaP) are important biomaterials for bone regeneration. This study demonstrates how a multi-component CaP formulation can guide bone formation beyond the normal physiological range. The study shows successful bone formation and remodeling in sheep models using this CaP formulation, and the presence of woven bone and vascularized lamellar bone in the pores of the CaP material.

Summary: Barley, rye, triticale, oat, sorghum and millet flours were analyzed after roasting or extrusion treatment to investigate the structural changes in starch and protein molecules. Extrusion treatment led to more extensive changes in both starch and protein structure compared to roasting treatment. The changes included alterations in protein secondary structure and disulfide bond conformation, as well as complete gelatinization and amylose-lipid complex formation in the starch structure. The rheological properties of the doughs were also affected by these structural changes, with extruded doughs exhibiting higher mechanical resistance.

Summary: The study reveals that the sclerites of the soft coral Ovabunda macrospiculata from the Red Sea are predominantly composed of the mineral vaterite rather than the stable calcite. This finding has implications for the formation and persistence of these structures in the face of anticipated anthropogenic climate change.

Summary: Layered Transition Metal Dichalcogenides (TMDs) are important materials with a diverse range of optoelectronic properties. This study investigates the spatial tailoring of TMDs through electron-beam patterning, achieving high resolution and demonstrating potential for nanoscale functionalization. The modulated properties were found to be dependent on various parameters, and the results were confirmed through spectroscopic analysis and density functional theory modeling. This research provides a robust method for property modulation and functionalization of TMDs at the nanoscale.

Summary: Deep cryogenic treatment (DCT) has been proven to effectively enhance the corrosion resistance of steels by reducing the formation of corrosion products, retarding their development and propagation, and decreasing surface cracking. The influence of DCT on each steel is dependent on the altered microstructure and alloying element concentration, making it an effective method for altering the corrosion resistance of steels.

Summary: This study investigated trichome biomineralization in 36 species of Mediterranean Brassicaceae from ultramafic and calcareous soils. The research found that soil chemistry had limited influence on trichome biomineralization, with calcium carbonate being the dominant biomineral, followed by calcium phosphate and silica. The study also observed that hyperaccumulation of Ni or variations in Mg:Ca ratios in the soil did not significantly impact the chemical composition of trichome biominerals.

Summary: Metal-ceramic nanocomposite coatings, such as YSZ and Ni-YSZ, deposited by EBPVD, were studied for their friction and wear behavior under different temperature conditions. The results showed that YSZ nanocomposite with 50 wt.% Ni content exhibited better wear resistance compared to other coatings, due to the formation of NiO from Ni during frictional heat.

Summary: Research shows that corals adapt to different depths and produce specific skeletal morphologies as ambient light decreases, attributed to physiological feedback between corals and symbiotic algae. Experimental transplantation reveals corals partially adapt and exhibit depth-specific properties. In mesophotic depths, corals have enriched organic matrices and overexpress transcripts encoding biomineralization tool-kit structural proteins.

Summary: One of the most conserved traits in the evolution of biomineralizing organisms is the taxon-specific selection of skeletal minerals. The modern asymbiotic scleractinian coral Paraconotrochus antarcticus in the Southern Ocean forms a two-component carbonate skeleton, with high-Mg calcite in the inner structure and aragonite in the outer structure, similar to the Cretaceous Coelosmilia. This highlights a close phylogenetic relationship and suggests the capability of forming bimineralic structures in scleractinian corals dates back at least 100 million years.

Summary: The study found that Stylophora pistillata exhibits rapid and pervasive gene expression changes under high temperature stress, with basic recovery ability below 34.5 degrees Celsius. However, at 34.5 degrees Celsius, large gene expression differences and weak recovery capacity were observed, resulting in high mortality and a microbiome dominated by opportunistic bacteria.

Summary: This study investigated the symbiotic relationship between Carnian corals and zooxanthellae in the Italian Dolomites, revealing potential widespread occurrence of this partnership. The findings suggest that Carnian scleractinian corals exhibited ecological adaptations similar to modern symbiotic corals, indicating that coral-algal symbiosis may have preceded the reef bloom at the end of the Triassic.

Summary: The study used metabolic isotope labeling and mass spectrometry imaging techniques to monitor the earliest seeds of Aβ plaque formation and revealed the aggregation dynamics of different Aβ species within plaques. It was found that the formation of structurally distinct plaques is associated with differential Aβ peptide deposition, with Aβ 1-42 forming an initial core structure followed by radial outgrowth and late secretion and deposition of Aβ 1-38.

Summary: The study investigated the relationship between feeding strategies, kleptoplast spatial distribution, and photosynthetic functionality in two shallow-water benthic foraminifera species. The results showed that the two species exhibited different feeding strategies, with one species having a higher autotrophic capacity despite both feeding on benthic diatoms. This may represent different stages in the evolutionary process of establishing a permanent symbiotic relationship or reflect different trophic strategies.

Summary: This study investigates the influence of light quantity and the presence of microalgal symbionts on the phototactic behavior of Aiptasia. The results show that phototaxis is a way for Aiptasia to adapt to the photosymbiotic relationship and optimize the light regime for its microalgal symbionts. It is also found that the photosynthetic activity of the microalgal symbionts suppresses locomotion in Aiptasia, likely to support a positive energy balance in the host.

Summary: According to isotope exchange experiments on foraminifera tests, the paleoseawater temperature record can be biased by up to 1 degrees C due to grain-boundary diffusion alone. The oxygen isotopic compositions of fossil foraminifera tests provide a continuous proxy record of deep-ocean and sea-surface temperatures over the past 120 million years. Through incubating foraminifera tests in O-18-enriched artificial seawater analogues, it has been shown that the oxygen isotopic composition of translucent calcite tests can be altered at low temperatures through rapid oxygen grain-boundary diffusion without visible ultrastructural changes.

Summary: The biomineralization of fish otoliths is regulated by macromolecules, such as proteins, particularly intrinsically disordered proteins like the Starmaker-like protein. Bioinspired mineralization experiments were conducted to investigate the effects of this protein on calcium carbonate biominerals, considering prior exposure to calcium or carbonate ions. The presence of the Starmaker-like protein significantly affected the morphology and protein distribution within the crystals, highlighting the importance of environmental conditions on its action.
