Research roundup: 6 cool science stories we almost missed
It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. September’s list includes a tantalizing hint of the elusive dark matter at the LUX-ZEPLIN detector; entangled Z bosons at the Large Hadron Collider; possible use of psychoactive substances in the Late Pleistocene; and an intriguing technical description of a telescope attributed to Galileo. A hint of dark matter? Physicists believe dark matter makes up roughly 85 percent of matter in our universe, with the strongest (but not only) candidate being so-called weakly interacting massive particles (WIMPs). But directly detecting WIMPs, or other alternative hypothetical dark matter particles, has eluded physicists for decades. We might have our first glimpse, however, courtesy of the LUX-ZEPLIN detector buried deep in a gold mine in South Dakota. Those potentially exciting results were presented in a scientific talk at the 2026 TeV Particle Astrophysics conference in Japan, with a preprint available on the arXiv. (It has been submitted to Physical Review Letters for peer review.) The announcement came with strong caveats: the signal is just a hint, well...
