Some cities in the northwestern, northern Indo-Gangetic Plain shielded from long-range aerosol pollution

Aerosol coming from outside was not adding to the pollution already seen in the cities that are referred to as urban aerosol clean islands. Instead, these cities in northwest and in the northern Indo-Gangetic Plain region were stopping or diverting the incoming aerosol and moving it around the city

India’s Scorching New Normal: The Escalating Heatwave Crisis and Paths to Resilience

Inspired by Ahmedabad’s success, over 130 cities and 23 States across India have developed their own Heat Action Plans. Alongside Heat Action Plans, a variety of heat-mitigation solutions have been implemented. Despite a variety of solutions implemented, significant challenges remain in addressing heatwave-related problems.

Urbanisation Shifts Peak Rainfall Inland, Increasing Flood Risk in Chennai

Storms interacting with Chennai’s urban environment consistently deposited their peak rainfall 16-20 km inland, whereas storms over rural areas peaked closer to the coast, within 8-12 km. Urbanisation thus plays a decisive role in altering the spatial distribution of rainfall, particularly by shifting the zone of heaviest precipitation farther inland

Two existing drugs offer hope to cure Russell’s viper bites

Russell’s viper venom show variations based on biogeography. So, antivenom efficacy is low for Russell’s viper in North India. Studies carried out in mice have demonstrated that two approved drugs were effective in countering systemic and lethal effects of the venom either individually or in combination from across India.
