An international team of biologists, chemists and physicists has used sophisticated 3D X-ray technology to investigate the tooth at an unprecedented level. A unicorn may be a mythical creature, but nature made something very similar under the Arctic ice. Wondering what? Well, the narwhal has a strange tusk that can reach nearly 10 feet long…

Sea otters returned to California’s Elkhorn Slough in 1984 when pollution had severely affected its ecosystem. When sea otters returned to California’s Elkhorn Slough in 1984, the estuary was already facing severe environmental pressure. The coastal wetland had high nutrient levels linked to its agriculture-dominated watershed, while eelgrass had fallen to an all-time low of…

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…

A lingcod guards its egg mass on the Annapolis (Image Credit: Michel Joseph via Artificial Reef Society of British Columbia) A retired Canadian warship that was deliberately sunk off British Columbia in 2015 has become an artificial reef supporting a growing community of marine life. The former HMCS Annapolis, measuring 113.1 metres in length, was…

Cement is one of the most widely used materials in construction, but its production comes with a high environmental cost. Circular Design Cement, a 2026 James Dyson Award project, is exploring a new approach to construction materials. The project uses everyday waste and industrial byproducts as recycled aggregates in cement-based materials designed for architectural applications….

A Scottish restoration project has returned 60,000 native oysters to the Firth of Forth, reviving a species that once formed vast oyster beds across an area roughly comparable to the size of Edinburgh. The Restoration Forth partnership originally aimed to return 30,000 European flat oysters to the estuary, but the target was later doubled after…

Isaac Newton, one of history’s most influential scientists, spent much of his life trying to understand the laws governing the natural world. His work transformed physics, mathematics and astronomy, but his approach to discovery was rooted in careful observation, experimentation and the search for underlying principles. One of his enduring observations was that truth is…

PC: Swiss Academy of Sciences A photograph shared online has helped scientists identify a hoverfly species that had remained a mystery for years. The insect, named ‘Monoceromyia ndidiae’, was photographed in the Dominican Republic and posted on iNaturalist. Its unusual appearance caught the attention of an entomologist, who began asking whether the fly represented something…

The European turtle dove population in the United Kingdom had fallen to just 2 percent of its peak population in the late 1960s. The species is Europe’s only migratory dove and has become the fastest-declining bird species in the U.K. As the festive season approaches, a bird forever linked with love, devotion and Christmas is…

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…

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…
