- May 21: iNoMed discovers Blackjack, a 40-celled 'almost-glide-symmetric' p21 oscillator whose two parts shift a block diagonally in opposite directions with uneven phase shifts, alike David Hilbert.
- May 15-17: David Bell modifies sawtooth 195 (the smallest known sawtooth by bounding box at 62 × 56) to start at 57 × 55. Entity Valkyrie, David Bell and EvinZL reduce this to a final bounding box of 48 × 50.
- May 11: Mitchell Riley uses a hacked QuFince fork to discover reductions to various syntheses, most notably paperclip quad 10G->8G, Cyclic 9G->8G, cha cha 12G->10G, scrubber with four covers 23G->16G, and square on four griddles 28G->20G.
On May 14, Riley further uses a different hack to find 1558 new 2-glider still life conversion components, and 14608 3-glider components; upon running the transfer.py script, this is expected to reduce a significant number of syntheses. - May 9: Nick Poyntz (in Catagolue comments) finds a 50-glider synthesis for quadruple eater 2 (a patch of the tablecloth), which DroneBetter, PK22 and KtT successively reduce to 28 gliders.
