After a cup of coffee is brewed, the grounds left behind are often discarded as waste. But researchers have found a way to turn them into a useful material for concrete. A 2023 study examined whether spent coffee grounds (SCG) could replace part of the sand used in concrete after being converted into biochar through…
Quote of the day by Alexander Graham Bell (Image: Wikipedia) In an age of constant notifications, endless open tabs and competing priorities, Alexander Graham Bell’s words feel genuinely surprising in how modern they still sound. “Concentrate all your thoughts on the task at hand,” he said. “The sun’s rays do not burn until brought to…
Nearly 100,000 sea urchins have been removed from three coastal sites in northern Norway by almost 500 volunteers working to bring back underwater kelp forests. Between April 2024 and May 2026, Rissa Citizen Science organised 23 restoration events at Sørsjetéen, Telegrafbukta and Øksfjord, with divers spending more than 20,000 minutes underwater clearing urchin barrens. The…
Restoring grazing by native large herbivores such as bison can produce sustained increases in native plant diversity In 1987, 30 bison from the Fort Riley Military Reservation were brought to Konza Prairie in Kansas. Nearly three decades later, researchers found that native plant species richness had increased by 103% at the local scale and by…
Singapore has turned part of a reservoir into a giant renewable-energy installation, covering about one-third of Tengeh Reservoir with more than 122,000 floating solar panels spread across 10 floating islands. The 45-hectare Sembcorp Tengeh Floating Solar Farm has a capacity of 60 MWp and generates electricity used to support five local water-treatment plants. The project…
A fossil found in southern Brazil is giving researchers a closer look at the reptiles that lived near the beginning of the archosaur lineage, the group that would eventually include dinosaurs and crocodile-line animals. The animal has been named ‘Silescelida acristata’ and is identified as an early-diverging eucrocopodan archosauriform from the Middle Triassic. A recent…
Ancient Polish burial reveals man with 2 skulls, 42-tooth necklace and battle axe (Image Credit: X/ @sputnik_brasil) Archaeologists investigating a Roman-period cemetery in Poland made an unexpected discovery when they came across a burial that was thousands of years older than the surrounding graves. Instead of a Roman-era burial, they found the nearly complete skeleton…

Researchers studying Scotia Sanctuary in south-eastern Australia found that 8 years after reintroduced mammals were given access to areas, the communities of insects emerging from the soil had changed. The mammals, including greater…
Nepal’s mid-hills are places where farming has long meant working with the landscape rather than against it. Terraces cut into steep slopes turn difficult ground into fields for maize, millet, rice and other crops, with generations of farmers maintaining the walls and soil that make cultivation possible. But the balance between people, farmland and wildlife…

The finding emerged from research into methane pyrolysis, a process that splits methane into hydrogen and solid carbon instead of producing CO2…
