A circadian oscillation (in the brain) of Drosophila spp. acts as a gating device restricting the emergence behavior of the adult to a limited fraction of each 24-hour cycle defined by that oscillator, but the oscillation does not gate intermediate steps of pupal development. Unlike the emergence act, such intermediate events in development occur at fixed times after prepupa formation and are totally independent of the phase of the ongoing oscillator that gates emergence behavior.

Dust emissions from open-pit mining pose a significant threat to environmental safety and human health. Currently, the range of dust suppressants used in coal mining is limited, often failing to account for their suitability across various stockpiles. This oversight results in poor infiltration after application, leading to insufficient crust formation and reduced durability.

ICMR-Vector Control Research Centre Field Station, Kottayam, Kerala, India.
West Nile virus (WNV) infection is emerging as a disease of public health concern in Kerala, India with recurring outbreaks since 2011. With its tropical climate, biodiversity hot spots of Western ghats, forest cover, plenty of water bodies and bird sanctuaries, Kerala provides an ideal ecological niche for vector breeding and transmission of WNV. In this article, we reflect on the peculiar features of the outbreaks of WNV fever in Kerala and highlight the knowledge gaps, the research priorities and the need for effective control measures.
