Artistic rendering of Penrose super-radiance: electromagnetic waves with selected rotation patterns are amplified as they interact with a system that appears to rotate at superluminal speeds. (Credit: Dalila Pasotti and Hadiseh Nasari) Physicists have successfully recreated some of the extreme physics of black holes inside a laboratory by building a stationary device that can copy…

Two Asian praying mantises are spreading across Europe, and scientists warn they may now threaten native wildlife Two giant Asian praying mantis species are rapidly spreading across Europe, leading scientists to officially classify them as invasive threats to native wildlife.These fast-breeding predators are steadily moving north, helped by rising global temperatures and the warm conditions…

Second pregnancy changes the brain in surprising new ways A woman’s brain changes in very different ways during her second pregnancy compared with her first, helping her adjust to the demands of raising a larger family.The discovery comes from a study by researchers at Amsterdam University Medical Center, published in the journal Nature Communications. Scientists…

Japan does not use modern nails to repair centuries-old temples. Instead, master craftsmen rely on an ancient woodworking technique (Representational AI photo) Centuries-old temples in Japan are still repaired without using modern nails, screws or metal brackets. In Japan, master carpenters instead continue to follow an ancient woodworking technique that has been passed down generations…

Why gold never tarnishes has finally been explained For thousands of years, humans have valued pure gold because it stays bright and shiny without becoming dull. Now, scientists have discovered that gold has a tiny self-protection system that actively stops oxygen from damaging its surface.The breakthrough comes from researchers at Tulane University, who found that…

It aims to deploy around 1,000 larger satellites by 2028 before eventually expanding the constellation to as many as 50,000 satellites by 2035 The United States has approved plans for what could become one of the most unusual space projects ever attempted — a satellite carrying a giant mirror designed to reflect sunlight back to…

An unidentified flying object shown in a photo first obtained by the New York Times. A routine US Navy training mission off the coast of Southern California in November 2004 turned into one of the most discussed unidentified flying object (UFO) cases in recent history. Nearly two decades later, the incident is still being debated…

Floating solar panels helped cut diesel use and also created a haven for salmon. (Picture source: Mowi.com) A salmon farm off the coast of Chile has found an unexpected benefit after replacing diesel generators with floating solar panels. While the project was launched to cut emissions and reduce fuel use, the new system also created…

According to JAXA, the entire flight lasted about 40 seconds. Japan has taken a significant step towards developing reusable rocket technology after its space agency successfully carried out the first lift-off and landing test of a prototype rocket, an area currently led by Elon Musk’s SpaceX.The Japan Aerospace Exploration Agency (JAXA) said the prototype lifted…

Imagine placing a flat piece of plastic on a warm surface and watching it fold itself into a fully functional robot without human hands, motors or complex assembly. It may sound like science fiction, but researchers at the Massachusetts Institute of Technology (MIT) demonstrated exactly that with a tiny, origami-inspired robot designed to assemble itself…
