Scientists have clarified how the Ladakh Magmatic Arc formed and evolved over nearly 130 million years in the north-western Himalaya. The record spans from the Jurassic to the Eocene (about 201 to 34 million years ago) and documents subduction beneath the Eurasian plate, magmatic activity, and eventual continental collision that helped build the Himalaya. The study shows Ladakh once stood above the Neo-Tethys Ocean and experienced ongoing tectonic activity as oceanic crust slipped beneath the margin. These findings illuminate pre-Himalayan processes and the long interplay between Indian and Eurasian plates, contributing to our understanding of regional geology and crustal growth.

India tests indigenous Floating LiDAR Buoy System off Tamil Nadu coast
India successfully tested an indigenous Floating LiDAR Buoy System developed by the National Institute of Ocean Technology (NIOT). The trial was conducted off Muttom, Tamil Nadu, to advance ocean observation and atmospheric data collection for offshore environments. The system combines a floating buoy with LiDAR technology to measure wind speed and direction at various heights above the sea. It can profile wind up to about 300 metres, delivering real-time data for weather forecasting and offshore planning. This development could enhance coastal research, marine operations, and renewable energy projects through better data accuracy.

IIT Guwahati develops MXene catalyst for hydrogen and desalination
Researchers at IIT Guwahati have developed a MXene-based catalyst with dual functions: efficient hydrogen production and seawater desalination. The two-dimensional material shows high electrical conductivity and features ultra-thin ribbon-like structures enhanced with ruthenium atoms. In laboratory tests, the catalyst enables electrolysis to produce hydrogen while supporting solar-powered desalination systems. The innovation targets two global challenges: clean energy and safe drinking water. While promising, researchers note that scaling up to industrial use and mass production will require further work. The dual-function material could improve energy efficiency and water security in coastal areas.

ZSI describes two new lichen moth species in Eastern Himalayas
Zoological Survey of India scientists describe two new lichen moth species, Caulocera hollowayi and Asura buxa, in the peer-reviewed journal Zootaxa on 2 March 2026. The discoveries originate from specimens collected in the eastern Himalayas, including Golitar in Sikkim and Panijhora in West Bengal. The new species increase India's Lepidoptera diversity and highlight the region’s biodiversity. Descriptions include morphology, habitat notes, and comparisons with similar species. This research supports ongoing fieldwork in biodiversity hotspots and informs conservation planning for high-altitude ecosystems. The findings contribute to global taxonomic databases and regional biodiversity strategies.
New species: Caulocera hollowayi and Asura buxa described in Zootaxa (2 March 2026).
Locations: Golitar, Sikkim; Panijhora, West Bengal.
Significance: expands Lepidoptera diversity in India.
Content: morphological descriptions and habitat data.
Impact: supports conservation planning and biodiversity databases.
ISRO–AIIMS MoU to advance space medicine research
ISRO has signed a memorandum of understanding with the All India Institute of Medical Sciences (AIIMS) to cooperate on space medicine and research. The MoU will study how the human body responds to long-duration space travel and develop medical systems for astronauts in orbit. It was signed by ISRO's HSFC director Dinesh Kumar Singh and AIIMS director Dr M Srinivas. Scientists from both organisations will conduct ground-based and space-based studies across physiology, immunology, nutrition, microbiome, neuroscience, and related areas. The partnership supports India’s future human spaceflight missions and strengthens cross-institutional capabilities.
Parties: ISRO and AIIMS sign MoU on space medicine.
Focus: human physiology and medical systems for long-duration space travel.
Impact: supports future human spaceflight missions.
New Lepidoptera species discovered in Sikkim and West Bengal
In the eastern Himalayas, scientists report additional Lepidoptera discoveries connected to recent moth descriptions. The team provides diagnostic characters and habitat notes to distinguish these new taxa from known relatives. Specimens were collected from Golitar in Sikkim and Panijhora in West Bengal, underscoring the region’s rich biodiversity and ongoing taxonomic work. This work builds on earlier identifications of Caulocera hollowayi and Asura buxa and contributes to the understanding of Lepidoptera diversity in India. The findings have practical value for future biodiversity surveys and conservation planning in northeast India.
