A 4200-hour campaign on FRB 20240114A finds that the highest-energy bursts account for most of the observed radio energy release, with a break in the energy distribution at ~2×10^40 erg and a linear DM rise of +0.96 pc cm^{-3} over 318 days.
New EP-FXT data on the 2024 outburst of magnetar 1E 1841-045 shows energy-dependent multi-peaked pulses, spectral hardening, BB temperature-pulse intensity correlations, and effective separation from supernova remnant emission.
Matching FRB QPOs to crustal modes constrains the neutron star mass to 1.00-1.76 solar masses, radius to ~13 km, and nuclear symmetry energy slope L to 59.5-96.8 MeV.
