In 2017, ADMX operated with the highest sensitivity of any axion experiment to date. In doing so, it ruled out a range of possible axion masses.

Now the ADMX collaboration released its latest results based on data taken in 2018. The new results rule out yet another mass range, four times wider than the first, while maintaining the same degree of exceptional sensitivity.

In October 2019, the Department of Energy announced that it has awarded scientists at its Fermi National Accelerator Laboratory funding to boost research on dark matter, the mysterious substance that makes up an astounding 85% of the matter in the universe.

The award will fund two Fermilab projects focused on searching for dark matter particles of low mass — less than the mass of a proton.
