The Viewpoint: How long can you stand on one leg? This simple test is the single clearest indicator of physical ageing
According to researchers, how long you can stand on one leg is the single clearest indicator of physical ageing and overall longevity.
Flipping an ancient genetic switch lets mice regrow ears
By flipping an ancient genetic switch, scientists enabled mice to regrow lost ear tissue instead of forming scars, a discovery that could unlock dormant healing abilities in other mammals.
Scientists 3D-print glass nanostructures with near-100% reflectance
Using a newly developed resin and a high-precision printing process, researchers have fabricated nanoscale glass structures that achieve nearly perfect light reflectance, opening up new possibilities for the material in advanced optics.
Scientists propose using magnets to ‘hear’ spacetime
Scientists have demonstrated how magnets from dark matter experiments can also serve as detectors for high-frequency gravitational waves, potentially revealing a new spectrum of cosmic signals.
New toothbrush-shaped ultrasound offers less invasive gum checkups
A new toothbrush-shaped ultrasound offers a less invasive and highly accurate alternative to traditional dental probes for monitoring gum health.
Age of oldest known human footprints in Americas confirmed by new study
By analyzing ancient mud, scientists have added a powerful new line of evidence confirming that humans walked in North America during the peak of the last ice age.
To build on Mars, scientists create self-sustaining ‘living’ material
Scientists have developed a self-sustaining material derived from microbes that can transform Martian dust into concrete for constructing future habitats.
The Real Animals Behind 5 Famous Monsters
This video reveals how many of history’s most famous monsters are likely folk memories of real animals, including extinct megafauna and misinterpreted wildlife that our ancestors once encountered.
Is the Universe a Fluke? The Problem of Fine-Tuning
Modern physics grapples with why the universe's fundamental constants appear "fine-tuned" for existence, suggesting either a radical new theory or the reality of a multiverse.
Why Physicists Built an Experiment the Size of a Sea
Deep beneath the Mediterranean, a massive neutrino detector has captured a particle so energetic it could rewrite our fundamental understanding of the cosmos.
