This week's featured article


Waterbear is an oblique spaceship constructed by Brett Berger on December 28, 2014. It was the smallest (in terms of bounding box) known oblique spaceship, superseding parallel HBK, until the discovery of Sir Robin in March 2018. It is also the first discovered "fast" oblique spaceship in Conway's Game of Life.

The helix, fanout devices and syntheses for the helix were found by Ivan Fomichev. The base reaction consists of a crawler consisting of a Herschel running on a track of gliders. The Herschel consumes a southwest glider and emits two gliders, one southwest and the other southeast, every 79 generations. Interactions between neighboring tracks are used to create the necessary components to recreate the helix.

Did you know...

  • ... that not all 1.00 volatility oscillators are phoenixes, but volatility 1.00 period 2 oscillators must be phoenixes?
  • ... that no pattern inside a 6×6 bounding box is a Garden of Eden?
  • ... that Garden of Eden patterns with only 45 ON cells have been found?
  • ... that it is known that no Garden of Eden patterns exist that are 1, 2, or 3 cells high, but that it is currently an open question whether a 4-cell-high GoE can be constructed?
  • ... that 6-cell-high Garden of Eden patterns were constructed as far back as 1973, but 5-cell-high GoEs were unknown until Steven Eker found some in 2016?
  • ... that in 2016, patterns were found that have great-great-grandparents but no great-great-great-grandparents?
  • ... that no way is known for a 3×3 pattern to be tiled into an M×N rectangle to produce a Garden of Eden, but that there are 4×3, 4×4 and larger tiles that can be repeated in this way to produce GoEs?
  • ... that there are spaceship stabilizations of agars?
  • ... that block is the only known finite strict still life where each living cell has exactly 3 neighbours?
  • ... that all strict still lifes up to and including 14 cells have been found by apgsearch in asymmetrical 16×16 soups?
