Unique chromium beam experiment unlocks cosmic ray origins and galactic chemistry
When a star dies, it generates an explosion of elemental nuclei and hurls them into space. Those elements, called cosmic rays, travel at nearly the speed of light, and eventually some of them encounter manmade detectors. Recording how many of each of these elements show up helps scientists better understand cosmic processes-but despite incredible research advances over the last century, uncertainty around how these elements transform as they travel across the light-years has left fundamental que
The science section covers breakthroughs in medicine, physics, biology, and technology. We surface discoveries that expand what humanity can do, from new treatments reaching clinical trials to engineering feats that seemed impossible a decade ago. Every link goes to the original publisher so you can read the full study or press release yourself.
