Scientists found that noise in dark matter detectors is caused by radon. Its atoms settle on internal metal grids and, when decaying, mimic signals from elusive particles. The created model matched data from the LUX and LZ experiments. This will help purify future experiments and maybe finally catch

Earth's internal structure is traditionally studied using seismic methods and gravimetry. But neutrinos—particles that barely interact with matter—offer a fundamentally different, gentle probe. The IceCube collaboration analyzed 10.7 years of muon neutrino observations with energies from 500 GeV to
