Dec 25th, 2025 - Although wolf-canine interbreeding has been considered extremely rare, the latest research shows that many present-day canines carry a small amount of wolf genes. A surprising study reveals that there is a trace of "wolf" lurking within the tiny body of a Chihuahua and the gigantic build of a St. Bernard. An international research team from the American Museum of Natural History and the National Museum of Natural History analyzed the genomes of 2,693 dogs and wolves and found that 64.1 percent of purebred dogs carry fragments of wolf DNA. Furthermore, a study of village dogs (free-roaming ... [Read More]

The explosion sent ripples through space-time and forged some of the universe's heaviest elements. Most massive ... [Read More]

Dec 24th, 2025 - Follow Earth on Google The night sky looks calm, but it's crowded and active. Gas drifts between stars, dust clouds hide newborn suns, and faint galaxies stack up in every direction. Much of that activity never reaches our eyes because it shines at wavelengths we can't see. Infrared light fills in those missing pieces. It reveals cold dust, drifting molecules, and the stretched glow of distant galaxies whose light has traveled for billions of years as the universe expanded. Without infrared vision, large parts of the cosmic story remain hidden. When astronomers measure many infrared ... [Read More]

Dec 24th, 2025 - Follow Earth on Google Planets do not show up fully formed. They grow inside thick disks of gas and dust that hide almost everything. For years, that mess has blocked a clear view of how solar systems take shape. Astronomers knew the basics, but the details stayed out of reach. Now there is a way to spot what the dust hides. By watching how young stars move, scientists can tell when something heavy is pulling on them. Those tiny shifts reveal companions that cannot be seen directly. It is a quiet method, but it works. Planets orbiting young stars A recent set of images pulls together views ... [Read More]

Dec 23rd, 2025 - 'Stingraybot' uses microbubble muscles controlled by ultrasound While it might sound like a weapon of oceanic destruction in the hands of Aquaman's arch enemies, the new "stingraybot" from a team at ETH Zurich (the Federal Institute of Technology of Switzerland) offers enormous promise for surgery, medical care, wildlife biology, robotics, and more, thanks to muscular membranes of microbubbles. At a mere 4 cm (1.6 inches) in width, the stingraybot swims using the same wavelike motions of the wing-like pectoral fins of real stingrays. Even more remarkably, this tiny ichthyo-droid requires no ... [Read More]

Dec 23rd, 2025 - The 12 best things to do in Alexandria, Egypt - Lonely Planet . Alexander the Great spotted the potential of its deep harbor and founded his Egyptian capital here, creating a bridge between the land of the pharaohs and ancient Greece. In the end, Alexander never got to see the city that bears his name. He died in Persia, and his body was brought back to Memphis by his general, Ptolemy, who established the last great Pharaonic dynasty. Alexander's body was later moved to Alexandria, but the location of his tomb remains one of the great unsolved mysteries of the Mediterranean. Over subsequent ... [Read More]

Dec 23rd, 2025 - For most people, dolphins sit in a safe mental category: intelligent, playful, sociable animals better known for aquarium tricks and beachside encounters than for anything genuinely threatening. They do not carry the menace of sharks or the fearsome reputation of other ocean predators. That assumption is exactly what a set of underwater recordings dismantled. The dolphins, trained by the US Navy to locate and mark underwater mines, were fitted with cameras to observe how they found and caught food in open water. The animals were not confined or staged. They swam, searched, pursued and fed as ... [Read More]

Dec 23rd, 2025 - When the James Webb Space Telescope (JWST) launched on Christmas Day 2021, astronomers hoped it would revolutionise our understanding of the early stages of the Universe. And they were right. Almost as soon as the telescope was switched on, astronomers saw something surprising: there seemed to be big, bright galaxies everywhere in the early Universe. They had predictions about how many galaxies they should see and how large those galaxies would be, but there were far more of them than they had imagined. This led to a flurry of headlines and a whole lot of head scratching in the field, ... [Read More]
