The RadioAxion experiment at Gran Sasso found no evidence for axion dark matter induced periodic modulations in 241Am decays and derived constraints on the axion decay constant for masses from 10^{-21} to 10^{-9} eV.
Axion-photon coupling imprints measurable Aharonov-Bohm and Berry phases in superconducting circuits and interferometers, projecting sensitivity to g_aγγ ~ 7.8e-14 GeV^{-1} at m_a ~ 1e-10 eV.
Realistic GRB parameters weaken previous ALP cooling bounds, but ALP-induced secondary fireballs in GRBs could still be probed via isotropic X-ray emission from future telescopes.
A spectator scalar field with strong portal coupling to the inflaton sources a stochastic gravitational wave background reaching Ω_GW h² ∼ 10^{-11} at frequencies 10^7-10^8 Hz for benchmark parameters σ/λ ≃ 10^4 and T_reh = 2×10^{14} GeV.
