How a small amount of rare earth metal shapes the environmental impact of magnets

How a small amount of rare earth metal shapes the environmental impact of magnets Gaby Clark Scientific Editor Robert Egan Associate Editor Magnets for electric cars and wind turbines contain only a small amount of the rare earth metal dysprosium. Yet, this metal is responsible for a large share of the environmental impact and costs, according to research by environmental scientists Stellina Samuel, Robert Istrate and René Kleijn. The study is published in the journal Sustainable Production...

Bridged or not? Scientists uncover a key step in hydrogenase assembly

June 1, 2026 dialog Bridged or not? Scientists uncover a key step in hydrogenase assembly Lisa Lock Scientific Editor Robert Egan Associate Editor How does nature build one of the most sophisticated catalytic metal centers found in biology? An international team of researchers has now resolved a long-standing debate surrounding the assembly of the active site of [FeFe]-hydrogenases—enzymes that rank among nature's most efficient catalysts for hydrogen production and consumption.

GDP rose 7.7% in FY26, 7.8% in Q4; RBI trims this year's projection to 6.6%

The Indian economy grew 7.8% in the Jan-March quarter as strong investment, sustained farm production and expansion of the construction and tertiary sector led to a robust demand, offsetting the anticipated adverse impact of the conflict in West Asia. Data released by the National Statistics Office (NSO) Friday with the revised 2022-23 base year estimated 2025-26 growth at 7.7%, compared with 7.6% in the second advance estimates released in Feb. This is comparably higher than the 7.1% growth...

AI-guided catalyst turns CO₂ and waste into fertilizer at industrially relevant rates

AI-guided catalyst turns CO₂ and waste into fertilizer at industrially relevant rates Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers from the National University of Singapore (NUS) have developed a computation-guided strategy to produce urea more efficiently from carbon dioxide and nitrate. By combining large language models, density functional theory calculations and experiments, the approach identified a cadmium-modified iron oxide catalyst that maintains high urea...

An Alternative Trajectory for Generative AI

arXiv:2603.14147v2 Announce Type: replace Abstract: The generative artificial intelligence (AI) ecosystem is undergoing rapid transformations that threaten its sustainability. As models transition from research prototypes to high-traffic products, the energetic burden has shifted from one-time training to recurring, unbounded inference. This is exacerbated by reasoning models that inflate compute costs by orders of magnitude per query.

Southern energy corridors set to dominate supplies to Europe, global leaders say

The rapid reshape of global energy supply routes and markets is a key focus at the Baku Energy Week 2026. Opening Baku Energy Week 2026, Azerbaijan’s President Ilham Aliyev said the “world cannot live without fossil fuels,” while also insisting that countries “should be judged on how they invest in renewables.” Speaking about Azerbaijan’s role in global energy markets, Aliyev said it was “difficult to imagine what the European market would look like without the South Caucasus,” underscoring...

Desi jugaads during heatwaves: India’s battle against 45°C temperatures

India is learning to live with a hotter future. From Delhi to Mumbai, temperatures are regularly crossing 45 degrees Celsius, heatwaves are lasting longer and cities are becoming giant heat traps due to rapid urbanisation and the growing urban heat island effect. But if there is one thing Indians are famous for, it is finding a jugaad for every problem.
