Spectral variation and pigmentary basis of ornamental and mimetic wing colour patches of swallowtail butterflies

This study quantifies spectral variation in wing color patches of swallowtail butterflies and identifies the pigment papiliochrome-II as the basis of sexual ornaments.

Crystallographic fragment binding studies of the Mycobacterium tuberculosis trifunctional enzyme suggest binding pockets for the tails of the acyl-CoA substrates at its active sites and a potential substrate channeling path between them

Disulfide-rich, cyclic peptides from Clitoria ternatea protect against β-amyloid toxicity and oxidative stress in transgenic Caenorhabditis elegans

This study shows that disulfide-rich cyclotides from Clitoria ternatea reduce β-amyloid toxicity and oxidative stress in C. elegans by inhibiting Aβ oligomerization and destabilizing amyloid assemblies.

Structural insights on the substrate-binding proteins of the Mycobacterium tuberculosis mammalian-cell-entry (Mce) 1 and 4 complexes

This study reports the structural properties of Mce substrate-binding proteins from Mycobacterium tuberculosis, revealing a novel heterohexameric arrangement and domain-specific interactions.

Performance of Bracon brevicornis (Wesmael) on two Spodoptera species and application as potential biocontrol agent against fall armyworm

This paper evaluates the performance of Bracon brevicornis as a biocontrol agent against Spodoptera litura and S. frugiperda, finding fifth instar larvae most suitable and confirming its effectiveness in field conditions.

Phenotypic diversity of Methylobacterium associated with rice landraces in Northeast India

The study examines Methylobacterium diversity in rice landraces from NE India, finding host-specific carbon use profiles and growth advantages, suggesting host-microbial relationships shape bacterial distribution.

FEMALE CHEMICAL WARFARE DRIVES FITNESS EFFECTS OF GROUP SEX RATIO

The paper investigates how female chemical warfare via quinones affects fitness in flour beetles with skewed sex ratios, showing non-sexual competition reduces female fecundity in female-biased groups.
