The world continues in a holding pattern for now, but there are some hopeful signs as countries around the world begin to emerge from the pandemic. Meanwhile, once again, here's our round up of recent papers and news items on fast radio bursts. We hope our readers continue to stay safe and healthy.

• FRB 20210303A was found at UTMOST in real-time using an automated GPU-accelerated/machine learning-based pipeline, with a DM of 366.9 pc/cc and a fluence of ~37.8 Jy-ms (ATel 14434).
• A new burst has been detected from FRB 180916.J0158+65 (FRB 20180916B) with the Medicina Northern Cross (MNC) at 408 MHz during its active phase on 3 March 2021 (ATel 14480).

FRB2021: After the success of FRB2020, planning for another virtual FRB conference this Northern Hemisphere Summer (~July) is underway. We hope to bring you more details soon!

Most talks and meetings are online for now, and many are available as recorded versions, so we are trying out a provisional section for public recorded talks. We welcome your feedback, and pointers to other talks of interest.
