FRB20250613A exhibits millisecond-timescale scattering variations, spectral depolarisation, and RM changes of ~300 rad m^{-2}, consistent with embedding in the dense stellar wind of a Be star binary companion in its low-metallicity dwarf host at z=0.0987.

Forward modeling of 90 localized FRBs from DSA and ASKAP yields n_z = 1.62^{+1.48}_{-1.57} for DM_host(z) ∝ (1+z)^{n_z}, excluding n_z=0 at 1σ.
A differential DM method using same-sky localized FRBs removes Milky Way contributions without Galactic models and produces a different constraint on Γ ≡ Ω_b H_0 f_d from current data compared to conventional approaches.
A second coherent radio burst spanning 704-4032 MHz with spectral index -2.18, 54% linear and 22% circular polarization, and an orthogonal polarization angle jump was detected from 2XMM J104608.7-594306, showing rare radio activity in sources thought to be radio-quiet.
FRB DMs correlate at 2.6-5 sigma with galaxies, weak lensing, CIB, CMB lensing, tSZ, X-ray clusters, SXRB and radio continuum, consistent with moderate feedback models while ruling out weak feedback at 3.5 sigma via SXRB-DM.
FRB dispersion measures directly constrain suppression of the matter power spectrum due to feedback at k ~ 0.1-3 h/Mpc, reduce posterior variance by a factor of ~8 at k~1 h/Mpc, and exclude extreme large-scale feedback scenarios at ~2 sigma.
CHIME/FRB has now cataloged 80 repeating FRB sources whose burst rates and upper limits are consistent with a power-law distribution implying 50-100% of all FRBs repeat.
A search of repeating FRBs identifies RM flare candidates in FRB 20121102A, FRB 20201124A, and FRB 20180916B, suggesting such events may be common and tied to dynamic magneto-ionic environments.
No statistically significant excess of associations is found between CHIME FRBs and Swift GRBs after spatial, redshift, and temporal filtering, consistent with random coincidences.
A 9-hour FAST observation covering ~4230 GCs in M49 found no FRBs and sets an upper limit of 4.7e-4 FRB GC^-1 hr^-1 above ~16.5 mJy ms fluence.
CHIME/FRB Catalog data favor a mixture of delayed progenitor channels for apparently nonrepeating FRBs with effective mean delay 1.426 Gyr over pure star-formation-rate tracing.
PATH is extended with three fitted P(m_r|z) prior models combined with P(z|DM), raising host-association confidence for ASKAP FRBs while showing fainter-than-expected host magnitude distribution.
Wideband observations show M28A giant pulses differ from FRB 20200120E bursts in duration, luminosity, timing statistics, and spectral structure, yielding no strong evidence for a direct link.
The PINK updates enhance the CELEBI FRB pipeline with better astrometry, time-frequency gating, polarization calibration, DM optimization tools, and a software container for improved efficiency and localization of events like FRB 20251019A.
FRBs serve as cosmological probes via dispersion measure, scattering, and Faraday rotation to constrain baryon distribution, expansion history, magnetic fields, and fundamental physics effects.
This review summarizes FRB properties and outlines how SKA capabilities will help identify progenitors and enable cosmological applications.
A reported periodic fast radio burst is reclassified as Galactic pulsar emission due to CHIME calibration and beam-pointing error.

Estimating Cosmological Parameters from Localized Fast Radio Bursts: A Method for Removing Milky Way Dispersion-Measure Contributions
A differential DM method using same-sky localized FRBs removes Milky Way contributions without Galactic models and produces a different constraint on Γ ≡ Ω_b H_0 f_d from current data compared to conventional approaches.

Signatures of Suppressed Matter Clustering revealed by Fast Radio Bursts
FRB dispersion measures directly constrain suppression of the matter power spectrum due to feedback at k ~ 0.1-3 h/Mpc, reduce posterior variance by a factor of ~8 at k~1 h/Mpc, and exclude extreme large-scale feedback scenarios at ~2 sigma.
