WGM Cooling paper published

Another slightly different paper… we did some work cooling really massive microspheres (micrograms) using their own Whispering Gallery Mode resonances, and it has just been published in Optics Express. Something easily big enough to see with your eye, cooled to a degree above absolute zero using nothing but light, amazing!
