मंगल ग्रह पर स्थित घाटियों के जाल से प्राप्त नए प्रमाण इस बात की पुष्टि करते हैं कि लगभग चार अरब वर्ष पहले नोआकियन काल में उष्ण और आर्द्र जलवायु धीरे-धीरे परिवर्तित होकर लगभग तीन अरब वर्ष पहले हेस्पेरियन काल तक ठंडी और हिममय हो गई थी।
Ecological droughts are on the rise in India's pristine forests and croplands, driven primarily by meteorological aridity and ocean warming, posing a major threat to the country's sustainability and food security.
New research reveals India's forest monitoring fails to capture social and economic health, leading to a comprehensive new blueprint that include vital social and economic dimensions and introduces a comprehensive list of 28 indicators and 64 sub-indicators to create a robust, evidence-based system for monitoring and reporting.

Sodium butyrate, a compound naturally produced by the gut microbiome, has been identified as a negative regulator of antibody-based immunity, compromising protection against viral infection in mice.
"Mathematical discovery is built from many steps, and each step is not so different from problem solving. This does raise legitimate questions of scaling, but claims about discovery involving “true creativity” while problem solving does not don’t deserve to be taken seriously."
This new effort provides a single, high-quality, and comprehensive database that maps the environmental, physical, and human landscapes of the catchments for all 5,715 large dams in the country.
Untreated stream water acts as a critical environmental reservoir, enriching the human gut with resistance genes to metals and biocides, while tubewell use drives a greater focus on traditional drug resistance.
A new study from arid Bikaner in Rajasthan has demonstrated a novel, farm-level strategy to tackle the interconnected crises of water scarcity, energy demand, and climate change. It demonstrates that simple changes to crop choice and soil management can dramatically improve the sustainability of farming systems.
The study found that the protein Tropomodulin-1 (TMOD1) and the FGFR-ERK signalling pathway are the essential molecular machinery that physically separates a mature Hydra bud from its parent.
A novel, beam-splitter-free architecture uses a single laser to create three entangled photon sources, allowing for simultaneous high-speed random bit generation and real-time security certification via the Bell test.
The strictly carnivorous Pallid and Montagu's Harriers are confirmed to be crucial secondary seed dispersers in India, rescuing viable seeds from the digestive tracts of their prey and playing an important role in maintaining the biodiversity of threatened grassland ecosystems.
