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

Brown is Gold: Why India Must Stop Calling Its Deserts as Wastelands

Let’s be clear: not all tree-planting is good. In Rajasthan’s Bikaner district, for instance, climate schemes involving tree planting have led to plummeting groundwater levels, soil acidification, and the loss of native grasses vital to both wildlife and pastoralists

A Genomic Portrait of India: Tracing Deep Ancestry, Health, and Disease Risk using DNA

Whole-genome sequencing of 2,762 Indians has unravelled the layers of ancestry, high intermixing with Neanderthals and Denisovans — which allowed the reconstruction of roughly half of the Neanderthal genome and one-fifth of the Denisovan genome using only Indian genomes — and high endogamy in India resulting in harmful mutations in some groups.

Can India reduce the number of zero-dose children by half in five years?

With a staggering 1.44 million zero-dose children in 2023, and only about nearly reaching the 2019 level of 1.4 million, can India reduce the number of zero-dose children by half of the 2019 level by 2030 to meet the IA2030 target?

Saving the seas: Conserving marine life to give a man a fish

Behind every dish containing a fish, prawn, or other seafood, lies a delicate ecological balance: healthy populations of these marine resources replenish themselves only when spawning habitats are protected and harvest pressures kept in check

Brain’s performance during, after exclusive ChatGPT usage drops, results in weaker neural connectivity

While exclusively relying on ChatGPT showed concerning outcomes, participants who wrote essays without any assistance and then began using ChatGPT showed higher memory recall, efficient tool use, strong re-engagement and enhanced neural connectivity. But participants who first used ChatGPT to write essays and then moved to unaided writing underperformed cognitively

Funding, infrastructure, general environment woes unattractive for senior international scientists to work in India: Venki Ramakrishnan 

To attract senior scientists from other countries, India needs a strong, stable commitment to science, which means not only much more funding but also more stable funding, much better infrastructure and, just as importantly, insulating science from politics and excessive bureaucratic rules and regulations

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.

Birds do not crash into aircraft on purpose. They are drawn to places we have built airports near garbage dumps, slaughterhouses, or feeding sites; due to poor urban planning, this is a commonplace in countries like India
