New quantum thermometer can measure a fever in a tiny worm

Science
Sept. 11 (UPI) -- Scientists have successfully outfitted an optical microscope with quantum sensors, creating a precise microscope-based thermometer, capable of sensing a "fever" in tiny nematode worms. Quantum systems are extremely sensitive to their surrounding environs, making them ideal for measuring in vivo temperature changes. Optical microscopes allow scientists to image microscopic structures in biological samples, and when combined with fluorescent biomarkers, can be used to observe biological processes.

"Our system effectively integrates fast particle tracking a...
