Fly larvae found to contribute to atmospheric methane pollutionChaoborus spp is a small fly species that is found all over the world (except in Antarctica). The insect spends one to two years of its life cycle under water in a larval state, in lakes no deeper than 70 metres. Larvae spend the day in lakebed sediment and rise to the surface at night to feed. They are equipped with air sacs that they can adjust to alter their depth in the water so as to migrate

Opinion: What resilience should mean to policymakersEvidence, and perhaps the experience of seemingly perpetual rain on one's face, suggests that the weather is one thing that is increasingly variable and difficult to predict. The impact of this goes beyond deciding whether to take an umbrella, or wear an extra layer of clothing, when you go out in the morning. Like other shocks, temperamental weather can and does affect various aspects of economic
