Credit: PixabayWhen people think of motors, they typically envision those in vehicles or machines. However, biological motors have existed for millions of years, especially in microorganisms. Many bacteria rely on tail-like structures called flagella, which rotate to propel them through fluids. This movement is powered by a protein complex known as the flagellar motor.The...
Credit: PixabayResearchers have found a way to preserve quantum properties in 3D materials using magnetic confinement. By stabilizing excitons—energy-carrying quasiparticles—through the magnetic properties of chromium sulfide bromide, they address a major challenge in quantum technology.Quantum effects typically only work at small scales, making them hard to apply in real-world systems like quantum computers. However,...
Not only did pterosaurs have hollow wing bones, but even the solid sections of those bones were full of microscopic canalsDepositphotosA new analysis of pterosaur bones could lead to lighter and stronger materials for aircraftYou might think that if a species went extinct tens of millions of years ago, its design would be too...

New research has identified why heart attacks cause more damage in malesDepositphotosA recent study has identified testosterone as the reason men suffer greater heart muscle damage after a heart attack than women. Researchers have also found a potential solution using an existing drug.The World Heart Federation's World Heart Report 2023 highlighted that heart disease...
An artist's impression shows a generic asteroid. Detecting the threat of near-Earth objects such as asteroids that could cause harm to our planet is a primary focus of NASA and other space organizations. ESA/FILEThe recently discovered asteroid 2024 YR4 has an average 2% chance of colliding with Earth in 2032. While the odds of an...
he biohybrid hand was floated in a liquid to reduce friction and allow the joints to float back to their original shape after electrical stimulationX. Ren, Y. Morimoto and S. Takeuchi, 2025/ Science RoboticsResearchers have made significant progress in creating an artificial hand that can grip and perform gestures by integrating lab-grown muscle tissue...
Retired wind turbine blades can be hard to repurpose because of their typically non-recyclable composite materials - which can include fiberglassEstormiz / Wikimedia CommonsWind turbines provide an excellent source of clean energy, but disposing of them when they are decommissioned presents a major challenge. Researchers in China have discovered a practical method to recycle...
