Finland to Operationalise World's First Permanent Nuclear Waste Vault

Finland is moving to operate the world's first permanent underground repository for highly radioactive nuclear waste, located beneath Olkiluoto Island. The Onkalo facility is designed to store spent nuclear fuel for up to 100,000 years, addressing long-term waste disposal challenges of nuclear energy. It sits 400–450 metres below ground in 1.9-billion-year-old bedrock, designed with a multi-barrier safety system: metal canisters, copper capsules, bentonite clay, and rock containment. The system ensures radiation isolation even if one barrier fails. The project responds to decades of waste management concerns; most countries currently use temporary storage. Critics cite long-term environmental risks, but proponents argue the policy reduces emissions while maintaining energy security.

Location: Onkalo underground repository beneath Olkiluoto Island, Finland.
Purpose: store spent nuclear fuel for up to 100,000 years.
Depth and geology: 400–450 metres below ground in very old bedrock.
Safety: multi-barrier system with metal canisters, copper capsules, bentonite clay, rock containment.
Rationale: addresses long-term nuclear-waste disposal challenges associated with energy generation.

China Discovers Cerium–Magnesium Changesite Lunar Mineral

Chinese researchers have discovered a new lunar mineral named Cerium–Magnesium Changesite, marking the 11th known mineral identified from the Moon. The finding was announced by the China Geological Survey and is considered a major development in extraterrestrial geology. Scientists believe the mineral could help improve high-efficiency LED technology and deepen understanding of lunar formation. The mineral was identified from a 44-gram solid lunar meteorite recovered in China. The meteorite had a dark molten shell, indicating its journey through Earth’s atmosphere. Researchers found the mineral colourless, transparent, and brittle, with crystal grains smaller than 10 micrometres.

IIT Ropar launches Agricultural Intelligence Ecosystem

IIT Ropar launched an advanced Agricultural Intelligence Ecosystem, the first fully integrated AI-based system for smart farming and agricultural decision-making. The system links sensors, data analytics and advisory services to help farmers optimize irrigation, fertilization and crop selection. The launch, announced in April 2026, marks a collaboration with government and industry partners to boost yields, reduce water use and raise rural incomes. The ecosystem integrates weather data, soil moisture, disease detection and market signals, enabling real-time decision support from sowing to harvest. The project will scale to other states over the next two years and support digital agriculture.

China identifies new lunar mineral Cerium–Magnesium Changesite

Chinese researchers have identified a new lunar mineral named Cerium–Magnesium Changesite, the 11th mineral confirmed from the Moon. The discovery, announced by the China Geological Survey, could aid high‑efficiency LED technology and deepen understanding of lunar formation. The mineral was identified from a 44‑gram Moon meteorite recovered in China, which had a dark molten shell from atmospheric entry. Cerium–Magnesium Changesite is colorless, transparent and brittle, with crystal grains smaller than 10 micrometres. Its unusual structure suggests formation under lunar conditions very different from Earth, offering a natural model to study rare earth elements in extraterrestrial environments and inspiring Earth-based material research.

NASA’s Nancy Grace Roman Space Telescope completes assembly

NASA has completed the assembly of the Nancy Grace Roman Space Telescope at the Goddard Space Flight Center in Maryland, entering final testing ahead of a 2026 launch. The telescope features a 2.4‑metre mirror and advanced instruments designed for wide-field sky surveys. Compared with prior observatories, Roman can image ten times the area of the sky and collect data up to a thousand times faster during surveys. Engineers report a smooth transition from construction to testing as mission teams prepare environmental and performance evaluations. Roman’s capabilities are expected to expand cosmology, exoplanet studies, and large-scale structure mapping.

Fully assembled at Goddard Space Flight Center
Launch planned for 2026
2.4-metre primary mirror
Wide-field sky surveys with ~100x Hubble area
data collection up to 1000x faster during surveys
Advances in cosmology and exoplanet science

India identified as cradle of Jamun evolution in new study

New research suggests that the Jamun tree, genus Syzygium, originated much earlier than previously believed, with India as a central hub of early diversification. Scientists propose an East Gondwanan origin dating back about 80 million years, challenging earlier ideas that Jamun began in Australia or Southeast Asia. Fossil records and molecular timelines show discrepancies with older estimates of around 51 million years for some lineages. The discovery relies on Miocene fossils around 20 million years old from Himachal Pradesh’s Kasauli Formation, used to re-evaluate how Syzygium spread across Asia and Africa. The study was led by the Birbal Sahni Institute of Palaeosciences (BSIP) and collaborating institutions.

Origin traced to East Gondwana about 80 million years ago.
India plays a central role in early diversification of Jamun.
Older ideas placed Jamun origins elsewhere.
Miocene fossils from Himachal Pradesh informed timelines.
BSIP led the study with collaborators.
Reevaluation of Syzygium dispersal across Asia and Africa.
