Stressed? Relax with some two-photon lithography. 💥 This widely used 3D nanoprinting technique uses intense laser beams to harden a liquid into precise shapes. It is expected to be a game changer in manufacturing, but in order to become more widespread, the process has to become more reliable. LLNL researchers and collaborators are turning to machine learning to make two-photon lithography more controlled and feasible for wide use. New findings posted in the journal “Additive Manufacturing” sho

Scientists just revealed what a photon actually looks like, and it changes everything. Not a point. Not a sphere. A three-dimensional electromagnetic field rippling through space and time. For decades, we couldn't calculate exactly how light and matter interact. We had to approximate, which limited what we could design. But researchers just cracked the math using a breakthrough called "pseudomode transformation." Now we have exact equations instead of estimates, and that precision unlocks techno
