    This reads like those “we’re all glowing!” pop-science papers that don’t mention “black body radiation”. (As in, every 300 K lump of matter in the universe emits a non-zero number of photons in part of the em spectrum that human eyes could see if there were enough of them.)

    Photons carry energy. Water does interact with light, which is why it gets dark deep in the sea. While I’m sure they’re measuring something, I don’t know if the obvious null-theory is skipped over by the reporter or the scientists. (What’s the control on that green light? Was it the same output wattage as others? What’s the thermal change with and without the light?)
