GEMINI. "On May 18, 2010, Andrew J. Wade announced a self-constructing pattern dubbed Gemini which creates a copy of itself while destroying its parent. This pattern replicates in 34 million generations, and uses an instruction tape made of gliders which oscillate between two stable configurations made of Chapman-Greene construction arms. These, in turn, create new copies of the pattern, and destroy the previous copy." https://lnkd.in/dzs-Kxk View in LinkedIn

LESS TIME THAN EVOLUTION. "Billions and billions of iterations of Conway's life have been played in the past three decades, even hosting competitions to generate familiar patterns like spaceships." https://lnkd.in/d8s-JuN View in LinkedIn

FIRST COMPLETE REPLICATOR. "The Game of Life was used to create the first self-constructing scheme. It creates a copy of itself while destructing its parent. And finally in 2013 Dave Greene created the first complete replicator containing its own instructions to replicate! Forty-three years after Conway's publication!" https://lnkd.in/d3B2FKW View in LinkedIn

THE HOPE. "First replicating creature spawned in life simulator. If you found a self-replicating organism living inside your computer, your first instinct might be to reach for the antivirus software. If, however, you are Andrew Wade, an avid player in the two-dimensional, mathematical universe known as the Game of Life, such a discovery is nothing short of an epiphany." (2010)." https://lnkd.in/d-ckTpQ View in LinkedIn

SHORTFALLS. "A Gemini spaceship is not a replicator, any more than a glider or other small spaceship is! A replicator is a pattern that makes copies of itself: the total number of copies of the pattern has to increase over time. If a pattern is "used up" in some way by the copying process, and is not capable of completing another cycle of replication after the first, then to be a true replicator it would have to produce two or more children simultaneously. Otherwise the pattern falls into some other category." https://lnkd.in/dNTQG9j View in LinkedIn

"THE TIMING MECHANISM used in photoperiodism seems in most cases to be based on endogenous circadian rhythms in light sensitivity, as first postulated by Bunning (1936). He suggested that the circadian clock consisted of two half cycles, photophil and scotophil. When light was received in the scotophilic phase, the daily cycle was perceived as an long day, but the absence of light during the scotophilic phase produced an short day response. Support for these circadian clock-based models was initially provided by physiological studies." https://lnkd.in/d_f7kfY View in LinkedIn

ENTRAINMENT BY PHOTORECEPTORS. "Synchronization of circadian clocks to light–dark cycles (often described as entrainment) is mediated by the action of multiple photoreceptors. In Arabidopsis, this includes at least four of the five phytochromes." https://lnkd.in/d_f7kfY View in LinkedIn

CIRCADIAN CHARACTERISTICS. "These rhythms all share the same fundamental properties: (i) their ability to become entrained, or synchronized, to diurnal changes in environmental conditions; (ii) persistence upon transfer to constant conditions; and (iii) a constant period over the physiological range of temperatures." https://lnkd.in/d_f7kfY View in LinkedIn

INTERLOCKING LOOPS. "Evidence is accumulating that the plant circadian clock comprises additional interlocking feedback loops, similar to those described in animal and fungal clocks." https://lnkd.in/d_f7kfY View in LinkedIn

TRANSCRIPTION PRESENCE. "Circadian control of transcription is widespread, and the list of plant genes regulated by the circadian clock is extensive. Microarray analyses suggest that ∼10% of all Arabidopsis genes regulated at the level of mRNA abundance and have identified multiple metabolic pathways under circadian control." https://lnkd.in/d4JRQbh View in LinkedIn
