Researchers have developed a novel quantum sensor capable of detecting faint signals, potentially aiding in the search for gravitational waves and dark matter. This new sensor effectively cancels out background noise that previously interfered with measurements. Separately, a team from Anhui University and the University of Science and Technology of China has created a 3D fiber micro-tweezers using femtosecond laser manufacturing, enabling precise manipulation of micro-scale objects with significantly higher force than traditional optical tweezers.
