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…
The discovery may also help explain why conventional traps and insecticidal baits can sometimes have trouble controlling infestations. why cockroach traps fail, how German cockroaches find their colony, how cockroach pheromones work, why cockroaches gather in groups, newborn cockroaches learn colony smell, cockroach feces used to identify colony members, using pheromones to control cockroach infestationsCockroaches…
The observations were made with the Daniel K. Inouye Solar Telescope (DKIST), a powerful 4-metre class solar telescope operated by the US National Science Foundation. The Sun may appear to us on Earth as a glowing ball of plasma, but its surface is far more active and turbulent than it looks, which has been proven…
Croatia was still dealing with the hidden legacy of the Balkan wars when scientists began looking to an unlikely ally: honeybees. Years after mines had been buried across fields, forests and rural land, uncertainty over their locations continued to complicate farming, development and everyday life. Traditional mine-clearance teams faced the difficult task of finding explosives…
Outside Casper, pieces of turbine blades cut through were lowered by a loader into a trench for years. Now, what they are being used for instead of being buried under the ground, is to make cement powder. And this transition is worth noting.The Casper Regional Landfill took its first decommissioned blades in the spring of…
Honeybees can be trained with nothing more than the promise of a sugary reward; they learn to pick out a specific face and keep picking it out later, even when it appears from a slightly different angle or sits among faces they have never encountered before. It is a strange and slightly humbling discovery, not…
Rice leaves behind more than a meal. After the grain has been processed, the tough outer husk is usually treated as an unwanted agricultural residue, with enormous quantities accumulating every year. Much of it has little obvious use and can become an environmental burden when it is burned or dumped. At Florida International University, chemistry…
Representative Image of jellyfish floating gracefully in a microgravity environment (AI-generated image) In 1991, NASA sent jellyfish into orbit as part of an experiment to understand how microgravity affects an organism’s sense of balance. The mission carried Aurelia jellyfish polyps aboard the space shuttle, where scientists induced them to develop into their next life stage…
Mercury is the smallest planet in the Solar System, only slightly larger than Earth’s Moon, but what lies beneath its battered surface is anything but small. Its metallic core stretches out to nearly 85 per cent of the planet’s total radius, leaving behind a rocky shell so thin it barely qualifies as a shell at…
A large coprolite of a carnivorous dinosaur found in Harding County, South Dakota, US. Image Credit: Poozeum/Wikipedia Around 540 million years ago, the biological landscape of Earth went through a huge transformation called the Cambrian explosion. During this era, the ancestors of most modern animal groups began to appear, depicting a massive surge in biodiversity….
