3D studio. In the new technique, a short laser pulse (red) starts the molecules in a gas jet (gray) rotating at different rates, so that they align a few picoseconds later, when they are hit by an electron pulse (green) that generates a diffraction pattern. A new algorithm converts this pattern into a 3D molecular structure.
