Microbial landscape of Indian homes: the microbial diversity, pathogens and antimicrobial resistome in urban residential spaces.

Background: Urban dwellings serve as complex and diverse microbial community niches. Interactions and impact of house microbiome on the health of the inhabitants need to be clearly defined. Therefore, it is critical to understand the diversity of the house microbiota, the presence and abundance of potential pathogens, and antimicrobial resistance.

The dynamic role of cohesin in maintaining human genome architecture.

Recent advances in genomic and imaging techniques have revealed the complex manner of organizing billions of base pairs of DNA necessary for maintaining their functionality and ensuring the proper expression of genetic information. The SMC proteins and cohesin complex primarily contribute to forming higher-order chromatin structures, such as chromosomal territories, compartments, topologically associating domains (TADs) and chromatin loops anchored by CCCTC-binding factor (CTCF) protein or other genome organizers. Cohesin plays a fundamental role in chromatin organization, gene expression and regulation.

Unraveling the fine-tuned lemon coloration of a pierid butterfly Catopsilia pomona.

Butterflies wings possess different types of scales to perform diverse functions. Each scale has many nano and microstructures, which interferes with light, resulting in unique coloration for each butterfly. Besides coloration, the arrangement of scales further helps in giving better survivability.
