This week's featured article The queen bee shuttle can refer to one of two period-30 oscillators (trans- version shown to the right) in which a queen bee travels back and forth between two blocks. Other stabilisations exist, such as ones that involve the eater 1, called the buckaroo. The queen bee shuttle is the basis of many known true period p30 guns, including the infamous Gosper glider gun. It was found by Bill Gosper in 1970 and was the first period 30 oscillator to be found. It is the smallest known oscillator with period greater than 15 and about the 18th most common naturally-occurring oscillator. 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 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 there are spaceship stabilizations of agars? ... that block is the only 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? ... that c/2 orthogonal and c/4 diagonal were the only speeds of spaceships seen to emerge from asymmetric soups on Catagolue until 2020, when a loafer appeared naturally? ... that all currently known standard Herschel conduits produce the same Herschel great-grandfather pattern, except for Fx158? ... that eater 1 is the smallest asymmetric still life? ... that in Life, no spaceship can exist with a speed of (m, n)c/x where (m + n)/x > 0.5? ... that even without using fixed-cost reverse caber tosser technology, an N-bit strict still life – specifically, some length of long long (...) boat or ship – can be constructed for any odd integer N using no more than 20 gliders, and for any even integer N using no more than 21 gliders, using a temporary tubstretcher? ... that even without using fixed-cost reverse caber tosser technology, some specific N-bit period-2 oscillators can be constructed for any even integer N using no more than 27 gliders, and for any odd integer N using no more than 29 gliders, using a temporary tubstretcher? ... that in 2022, a still life was found containing a finite region whose only predecessor is itself?           Showing 10 items out of 180 More did you know...
