    "summary": "Anderegg and colleagues showed that laser cooling could remain effective while calcium monofluoride molecules were held by light in an optical dipole trap. Simultaneous cooling increased the number loaded by up to a factor of five, and a heating-and-recooling test brought the trapped sample back to about 60 microkelvin.",
    "boundary": "The reported sample contained about 150 molecules, far from quantum degeneracy. Density estimates depend on a thermal model of the trap. The experiment concerns the stated molecular species and apparatus, not universal cooling of arbitrary molecules.",
