Scientists build micromotors smaller than a human hairUsing laser light instead of traditional mechanics, researchers have built micro-gears that can spin, shift direction, and even power tiny machines. These breakthroughs could soon lead to revolutionary medical tools working at the scale of cells.... - ●NASAās Perseverance just found new evidence that Mars could have been habitableJezero Craterās rocks reveal three stages of water activity, shifting from hostile acidic fluids to more life-friendly alkaline ones. Perseveranceās discoveries guide future sampling and strengthen the hunt for past life on Mars....
- ●The Moon could finally reveal dark matterFaint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold dark matter, providing long-sought answers about the invisible backbone of the Universe....
- ●White dwarf caught devouring a frozen Pluto-like worldAstronomers have detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf star, offering the clearest evidence yet that icy, life-delivering objects exist beyond our Solar System. The find suggests fragments like comets and dwarf planets may be common ingredients of planetary systems....
- ●Why Alaskaās salmon streams are suddenly bleeding orangeWarming Arctic permafrost is unlocking toxic metals, turning Alaskaās once-clear rivers into orange, acid-laced streams. The shift, eerily similar to mine pollution but entirely natural, threatens fish, ecosystems, and communities that depend on themāwith no way to stop the process once it starts....
