Fermilab Muon g-2 Experiment Sets New Direct Detection Limit on Muon Electric Dipole Moment

On August 12, 2026, the Muon g-2 Collaboration announced that a new analysis based on 25% of the data from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory has produced the most sensitive direct measurement of the muon's electric dipole moment to date. The results show that if a muon electric dipole moment exists, its magnitude is below the current detection threshold of the experiment. The muon electric dipole moment values measured by Fermilab across different data-taking periods were compared with previous results from Brookhaven National Laboratory. The combined Fermilab value is consistent with zero (no observation). Although the experiment uses positive muons, results are typically reported for negative muons, which reverses the sign of the measured value...

Russian Researchers Develop Highly Sensitive Radio Astronomy Sensor for Axion Dark Matter Detection

Researchers from the Institute for Physics of Microstructures of the Russian Academy of Sciences and Nizhny Novgorod State Technical University have developed a radio astronomy sensor whose sensitivity is reportedly two to three times higher than that of existing international counterparts, and it has been granted a Russian patent. The device is designed for detecting weak electromagnetic radiation signals and can be used in frontier physics experiments such as cosmic microwave background radiation studies and axion dark matter searches. The researchers explain that this type of detector is essentially an electromagnetic radiation receiver. When electromagnetic radiation strikes the sensitive element, the electron temperature rises, thereby altering the recorded signal. To improve detection sensitivity, the research team introduced a thin hafnium layer into the structure, which acts as a thermal...
