Dark Matter's Shifting Compass The development of a tabletop magnetic sensor capable of detecting signals billions of times fainter than the Earth's own magnetic field marks a significant breakthrough in the hunt for dark matter particles.
The Levitated Magnet Magnetometer (LeMaMa), created by a Chinese German team, operates at room temperature and has the potential to revolutionize our understanding of the universe.
Magnetic fields are ubiquitous, ranging from incredibly strong fields generated by hospital MRI machines to vanishingly weak signals produced by human brain activity.
