Tasmania introduced brown trout from England for sport More than 160 years after Tasmania introduced British brown trout to create a major recreational fishery, conservation workers are building artificial barriers and clearing entire waterways to save a tiny native fish from extinction. The Swan galaxias (Galaxias fontanus), a small, scaleless freshwater fish found only in…

A tiny insect became one of the earliest living passengers sent towards space, long before astronauts were routinely orbiting Earth. In 1947, fruit flies were loaded onto a captured German V-2 rocket in New Mexico as scientists began testing what happened to life above the atmosphere. The experiment was primitive by modern standards, but it…

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…

Bycatch, the accidental capture of animals in fishing gear is considered the world’s greatest direct human-caused threat to dolphins and porpoises. Off the coast of Cornwall, a set of underwater sensors was listening to the ocean when it detected something researchers rarely get to see. According to an online report by Phys Org, two harbor…

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…

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….

Pee breaks are one of the most relaxing times in the office when you finally get to have some sane moments to yourself. Which is why most employees take numerous such breaks within a day. But what if your normal pee break had you secretly contributing to the generation of electricity?Two hundred and sixty men…

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…

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…
