Article Synopsis
  • - The study examines how a very severe tropical cyclone affects sea turtle nesting habitats and suggests management strategies to protect these areas amid changes in the coastal landscape and sediment conditions.
  • - Findings indicate that while the immediate impacts on nesting sites are short-term, long-term effects like plastic pollution and altered sediment characteristics could hinder nesting success and exacerbate flooding.
  • - Recommendations include ensuring specific cross-sectional areas for estuaries to maintain stability, as well as involving local communities in post-cyclone clean-up efforts to support the conservation of sea turtle habitats.

Copper iodide, an environmentally friendly material abundant in nature, holds great significance for room temperature thermoelectric (TE) applications owing to its high Seebeck coefficient and optical transparency. However, to fully unlock its thermoelectric potential and match the performance of conventional TE materials, there is a need to further enhance its electrical conductivity. In this study, we have successfully synthesized nano-crystalline powders of both undoped and aluminium-doped CuI at room temperature using the chemical precipitation method in an ethanol medium.

SARS-CoV-2, severe acute respiratory syndrome coronavirus-2, causes coronavirus disease- 2019 (COVID-19). Mostly, COVID-19 causes respiratory symptoms that can resemble those of a cold, the flu, or pneumonia. COVID-19 may harm more than just lungs and respiratory systems.

The members of the genus are key players in the removal of petroleum hydrocarbons from polluted marine environments. More than half of the species were described in the last decade using 16S rRNA gene phylogeny and genomic-based metrics. However, the 16S rRNA gene identity (<94 %) between some members of the genus suggested their imprecise taxonomic status.

The COVID-19 pandemic has spurred an unprecedented movement to develop safe and effective vaccines against the SARS-CoV-2 virus to immunize the global population. The first set of vaccine candidates that received emergency use authorization targeted the spike (S) glycoprotein of the SARS-CoV-2 virus that enables virus entry into cells via the receptor binding domain (RBD). Recently, multiple variants of SARS-CoV-2 have emerged with mutations in S protein and the ability to evade neutralizing antibodies in vaccinated individuals.

Intermittent drought and an incidence of grain mold disease are the two major constraints affecting sorghum production and productivity. The study aimed at developing drought-tolerant sorghum varieties possessing a high protein content and tolerance to grain mold with stable performance using additive main effects and multiplicative interaction (AMMI) and genotype and genotype × environment interaction (GGE) biplot methods. Systematic hybridization among the 11 superior landraces resulted in subsequent pedigree-based breeding and selection from 2010 to 2015 evolved 19 promising varieties of grains such as white, yellow, and brown pericarp grains.

We study the effect of reaction times on the kinetics of relaxation to stationary states and on congestion transitions in heterogeneous traffic using simulations of Newell's model on a ring. Heterogeneity is modeled as quenched disorders in the parameters of Newell's model and in the reaction time of the drivers. We observed that at low densities, the relaxation to stationary state from a homogeneous initial state is governed by the same power laws as derived by E.

Article Synopsis
  • Five sponge specimens from Little Rann of Kutch, India, were studied to analyze their associated microbiomes, focusing on Planctomycetes using both metagenomic and anaerobic enrichment cultures.
  • The 16S rRNA gene analysis showed high bacterial diversity, identifying 376 Operational Taxonomic Units (OTUs) from 41 phyla, with Proteobacteria being the most prevalent at 38%.
  • The study found significant functional capabilities through KEGG annotation, indicating potential roles in metabolism and degradation, while FISH analysis confirmed the presence of anammox-planctomycetes, suggesting the discovery of new related species.

Two pink-coloured, oxidase-catalase-positive, salt and alkali-tolerant planctomycetal strains (JC635 and JC645) with pear to spherical-shaped, Gram-stain-negative, motile cells were isolated from Chilika lagoon, India. Both strains share highest 16S rRNA gene sequence identity with members of the genus Rhodopirellula (< 94%) and Roseimaritima (< 94%) of the family Pirellulaceae. The 16S rRNA sequence identity between the strains JC635 and JC645 is 96.

We study heterogeneous traffic dynamics by introducing quenched disorders in all the parameters of Newell's car-following model. Specifically, we consider randomness in the free-flow speed, the jam density, and the backward wave speed. The quenched disorders are modeled using beta distributions.

In the emerging scenario of increasing antibiotic resistance and pathogen transmission channels, the grave danger posed by bacterial endospores in critical fields like food industry, health and medicine highlights the urgent need to develop efficient probes for their detection; their sturdy and impermeable multilayer coat makes desirable methods like fluorescence imaging extremely difficult. Selective imaging of the endospores in the presence of the bacteria is even more challenging. Furthermore, it is preferable to maintain the dormant state of endospores through the imaging process, if extended monitoring is required; many of the available techniques involve lethal germination or destruction of the endospores.

Misfolding of human islet amyloid polypeptide (hIAPP) into insoluble aggregates is associated with Type 2 diabetes. It has been suggested that hIAPP toxicity may be due to its accumulation in pancreatic islets, causing membrane disruption and cell permeabilization, however the molecular basis underlying its lipid association are still unclear. Here, we combine solid-state NMR, fluorescence and bright field microscopy to investigate hIAPP - lipid membrane interactions.

Epidermal growth factor receptor (EGFR) is a known target in cancer therapy and targeting the receptor has proven to be extremely successful in treating cancers that are dependent on EGFR signaling. To that effect, targeted therapies to EGFR such as Cetuximab, Panitumumab-monoclonal antibodies and Gefitinib, Erlotinib-tyrosine kinase inhibitors have had success in therapeutic scenarios. However, the development of resistance to these drugs makes it necessary to combine anti- EGFR therapies with other inhibitors, so that resistance can be overcome by the targeting of alternate signaling pathways.
