Six decades ago, Dutch elm disease swept across the United States, killing an estimated 100 million American elms that once shaded streets, parks and college campuses from coast to coast. The fungus, carried by bark beetles, turned majestic, vase-shaped trees into dead standing skeletons and changed the look of countless towns. Now, in a bold…

In 2003, Nasa researchers reported that freshwater snails carried into orbit aboard the Space Shuttle had mated and reproduced during their mission, allowing their gravity-sensing organs to develop entirely under microgravity. According to the study published in PubMed, tittled ‘Otoliths developed in microgravity‘ formed part of the results of the STS-90 Neurolab Spacelab mission, a…

In 2005, five thick-toed geckos left Earth aboard the unmanned Russian spacecraft Foton-M2, embarking on a 16-day orbital flight with no access to food or water. The mission, a joint undertaking between Nasa and the Russian Academy of Sciences, was designed to test whether a reptile species could serve as a viable model for studying…

In January 1960, Nasa launched the rhesus monkey Miss Sam aboard a Little Joe rocket from Wallops Island, Virginia, to test the launch escape system built for Project Mercury. The flight was designed to confirm that the escape tower could pull the capsule clear of its booster during an abort, a safeguard critical to any…

The universe has fascinated humanity for centuries, but understanding it requires more than simply looking at the stars and planets. Galileo Galilei, one of history’s most influential astronomers and scientists, offered a powerful way of thinking about nature, arguing that the universe could be understood only by learning the language in which it was written….

Representative Image (AI-generated) What happens when waste from a coal-fired power station is placed beneath the sea? In 1989, researchers in the UK built an experimental artificial reef from 50 tons of stabilised coal-fired power station waste, and marine life began moving in almost immediately. The unusual experiment took place in Poole Bay, off the…

Engineers in Switzerland have worked out how to make miniature robots fly and steer without a single motor, magnet or battery on board. Researchers at the École Polytechnique Fédérale de Lausanne have built hollow structures that turn sound waves directly into thrust, drawing on Helmholtz resonance, the same physics behind the low hum produced by…

Quote of the day by Neil deGrasse Tyson (Image: Wikipedia) Neil deGrasse Tyson‘s words present education as something considerably bigger than simply memorising facts. “As an educator, it’s my duty to empower you to think,” he said. “So that you can go forth and think accurate thoughts about how the world is put together.” He…

Diamond has long been regarded as a nonpiezoelectric material. Now, researchers have identified a piezoelectric effect in ultrathin, ultraflexible polycrystalline diamond membranes. Piezoelectric materials produce an electrical response when they are mechanically pressed, bent, or stretched. In the study, the researchers found that the effect in diamond membranes varies with their thickness, with the strongest…

More than two kilometres beneath the surface of the Pacific, off the coast of Oregon, an active underwater volcano has been hiding one of the strangest landscapes ever mapped on the seafloor. Using robotic vehicles capable of withstanding crushing depths, scientists from the Monterey Bay Aquarium Research Institute have spent more than two decades surveying…

At a time when laundry was one more task competing with school, travel and family responsibilities, a Kerala schoolgirl began thinking about a surprisingly simple alternative to the washing machine she did not have. Remya, who was studying in the 10th standard, was already spending hours travelling to school each day and helping her twin…

For years, St. John’s wort was treated as a useful medicinal plant in parts of Europe. In northern California, its reputation became very different. The yellow-flowered weed spread across pasture and open land, reducing the value of grazing areas and creating another problem for livestock because animals that consumed enough of it could become dangerously…
