This approach uses precision measurement techniques and devices from atomic, quantum, and condensed - matter physics to detect tiny signals due to new particles or forces. (science.sciencemag.org)
In addition to the challenge of picking out such tiny signals, the researchers had to contend with an effect that initially muddled the data: starspots, dark patches on the surface of stars. (sciencedaily.com)
