Greetings from Research Matters!

In this week’s stories: A new beam-splitter free quantum random number generator, key protein in Hydra reproduction, diversifying crops and better field management practices to improve farming, superbug evolution in tribal groups without antibiotics, a new detailed dam health map for India, and more...

There is also STEM news from other Indian media outlets and public STEM events to attend. Don’t forget to check out Scidle - the science wordle, for a new science word every day.

Delegate registrations are now open for the 3rd Indian Near Surface Geophysics Conference & Exhibition (INSGC 2025).

Stories in this edition

Novel ‘beam-splitter-free’ random number generator achieves record speed and self-testing | PRL, Ahmedabad, IIIT Gandhinagar, others.

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.

Researchers identify key protein that triggers the molecular pinch during budding of the immortal Hydra | ARI Pune

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.

Field management practices and low irrigation crops can beat the Water-Energy-Food-GHG Nexus | ICAR-Central Arid Zone Research Institute, others

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.

New study uncovers environmental drivers of Superbugs in Indian tribal communities | Anthropological Survey of India, University of Hyderabad

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.

DAM-IN, a new mega-dataset, maps the health of the Dam catchments across India | IIT Jodhpur

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.
