A mosquito does not need to die for its role in malaria transmission to be interrupted. That idea sits at the centre of a 2025 study led by researchers associated with Harvard T.H. Chan School of Public Health, who tested a different way of using bed nets: instead of relying entirely on insecticides to kill…
On the afternoon of 21 August 2017, millions of people across the United States looked towards the Sun as the Moon moved across it. For most viewers, the eclipse became a short-lived memory once the sky returned to normal. For Nia Payne, a 26-year-old woman in Staten Island, the event left something behind. Within days,…
For generations, prairie dogs were often treated as a problem rather than an ecological asset. Their burrows were blamed for competing with livestock, while their colonies were targeted through shooting and poisoning across large parts of their former range.But removing them had consequences far larger than the disappearance of one small mammal. Scientists studying black-tailed…
Total Solar Eclipse. Image Credit: Bob Linsdell/Wikipedia On 12 August 2026, a total solar eclipse will take place, which will cross the Northern Hemisphere from Siberia to the Mediterranean. This rare celestial event is expected to attract millions of observers from many continents. The path of totality (the narrow track or strip of land where…
A critically endangered female red handfish, Thymichthys politus. (Photo: Joel Sartore) For 20 years, photographer Joel Sartore has been building a huge visual record of the world’s animals. His project, called the Photo Ark, has now reached another major milestone with its 18,000th species- the critically endangered red handfish. The milestone photo was announced by…
Representative Image of Australian magpies cooperating to remove tracking devices from one another (AI-generated image) Researchers in Queensland fitted five Australian magpies with tiny GPS trackers, hoping to map their movements and understand how age, sex or rank affected the way the flock behaved. The birds had other plans. Within about ten minutes, an untagged…
A 14-year-old Georgia student has turned a common kitchen concern into an award-winning science project. Sirish Subash, a ninth grader from Snellville, built PestiSCAND, a handheld device designed to detect pesticide residues on fruits and vegetables. As reported by USA Today, his invention earned him the title of America’s Top Young Scientist in October 2024,…
In September 2022, Nasa carried out a mission that had never been attempted before: deliberately crashing a spacecraft into an asteroid to change its path through space. The target was Dimorphos, a small moonlet orbiting a larger asteroid called Didymos. Neither object posed any danger to Earth, which made the pair an ideal testing ground…
Benjamin Franklin (Image: Wikipedia) Two people can spend a lifetime accumulating whatever they consider valuable and end up with completely different kinds of wealth to show for it. One collects money, property, and possessions, each one clearly priced, each one able to be counted. The other spends that same effort building something that resists being…
America is quietly building a network of nuclear-powered nodes on the ocean floor that could charge drone submarines for close to three decades without a cable, a support ship or a single resupply run. The fuel behind this project is strontium-90, a radioactive by-product that has sat in government storage for decades, and the Pentagon…

Announced by the University of Cádiz, the structure, known as Dolmen I of the La Lentejuela necropolis stretches about 13 metres, or roughly 42 feet, and contains multiple…
Earth’s core holds far more gold than anyone can reach. More than 99.999 per cent of the planet’s stores of gold and other precious metals lie buried under 3,000 kilometres of solid rock, locked away within the metallic core and far beyond the reach of humankind. For decades, geologists assumed this vast reserve was permanently…
