Breathable Crystal Revolutionizes Oxygen Use

Did you know... scientists have invented a crystal that literally *breathes* oxygen,

just like your lungs? In August 2025, researchers in Korea and Japan, led by Professor

Hyoungjeen Jeen, unveiled this incredible metal oxide crystal made of strontium, iron,

and cobalt. When gently heated, it releases oxygen atoms... then sucks them

right back in when cooled — over and over, without ever breaking down.

Professor Jeen said: "It's like giving the crystal lungs — it inhales and exhales oxygen on

command." Unlike old materials that were fragile or needed extreme heat,

this one works under milder conditions and stays perfectly stable. Imagine the future:
