This week's featured article The lightweight spaceship (or LWSS for short) is the smallest orthogonally moving spaceship, and the second most common spaceship (after the glider). It moves orthogonally at c/2 and has period 4. It was found by John Conway in 1970. Read more... In the news April 30: Christopher D'Agostino posts a modification of a partial Herschel-to-Herschel converter pointed out by AlbertArmstain, producing an easily connectable and completely Spartan L141 conduit with three output gliders including the FNG and SNG. April 19: Nathaniel Johnston completes a "Herschel Tracks Tutorial" YouTube video about creating custom oscillators using Herschel conduits. April 8: David Bell constructs and refines a puffer demonstrating that all sufficiently high c/4 diagonal rake periods are achievable. Matthias Merzenich uses this to construct a clean p3532+4N rake.

Did you know... ... that the first self-constructing Conway's Life pattern was built in 2010? ... that the first glider synthesis for a c/3 spaceship was completed in 2014? ... that the first "macro-spaceship" gun (a Gemini spaceship gun) was constructed in 2010, followed by the HBK gun in January 2015 and a Demonoid gun in December 2015? ... that the waterbear was the first known high-speed oblique spaceship, many orders of magnitude faster than Gemini spaceships and half-baked knightships? ... that there are no known direct reflectors for lightspeed wire signals, or for signals in 2c/3 wires, but that very large reflectors for these signals can be constructed using stable or periodic circuitry? ... that 24 ten-cell patterns exhibit infinite growth, with 17 unique pattern types, but that it has been proven that no nine-cell pattern exhibits infinite growth? ... that all still lifes up to 21 bits have a known glider synthesis, but that there is a 236-cell still life that cannot be synthesised, so there is a population threshold between these at which not all still lifes can be constructed? ... that the French kiss remained without a glider synthesis until 2013, and there are still fourteen 17-bit p2s that have not been successfully synthesized? ... that Adam P. Goucher's distributed Catagolue soup-search project, started in February 2015, has tested several orders of magnitude more random soups than any previous such project, and has contributed to the reduction of many glider construction recipes? ... that with the appearance of the 0E0P metacell, the number of periods for which strict volatility 1 oscillators were known went from 12 to infinity?           Showing 10 items out of 102 More did you know...
