A standard chemical rule says: symmetrical molecules bend for stability. But in a magnetic light trap, they stay straight and become magnets. New research opens a path to 'sculpting' molecules with light.
🎯 Without the echo chamber, H₄ or C₄H₄ rings distort chaotically. Inside, they freeze into a perfect shape, and a current runs endlessly around them — you get a magnet with no wires or batteries.
🎬 Like sci-fi force fields, light echo reassembles molecules to order — birthing materials with unprecedented traits.
