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

CLOCK CYCLE. "Accumulation of the TOC1 protein at night promotes transcription from the LHY and CCA1 promoters, thus initiating a new cycle." https://lnkd.in/d_f7kfY View in LinkedIn

FRAGMENT FROM NATURE continues for the second of three weekends on the theme of plant clocks, why they exist, and how they work. These mechanisms are ubiquitous across taxa, and are sophisticated in construction. In many (or most) cases, when external stimuli are removed, they keep ticking. Living things, it seems, are obsessed with time, and have put a lot of ingenuity into marking its passage. I shall refrain from quoting TS Eliot. View in LinkedIn

BUGS, MUTATIONS, ERRORS. "All software contains bugs, that is a given. There is an established body of evidence out there to support the notion that producing error-free software is an impossibility." https://lnkd.in/e6GQx2z View in LinkedIn

COMPUTER VIRUSES, or bugs, represent a very interesting topic. In genetics, errors or mutations, are the sources of genetic innovation, the drivers of evolution, and through selective pressures acting on the diverse bell-curve of possibilities, drives adaptation to new niches and fitter organisms. How do code errors function in the computing ecosystem? View in LinkedIn

INSPIRATION FOR VENUS. "Dewdney proposed a game called "Core Wars", in which hackers create computer programs that battle for control of a computer's "core" memory. Since computer programs are just patterns of information, a successful program in core wars is one that replicates its pattern within the memory, so that eventually most of the memory contains its pattern rather than that of the competing program." https://lnkd.in/esA_k7j View in LinkedIn

RASMUSSEN'S VENUS. "In VENUS, genetically-programmed digital organisms occupy memory, and each block of memory has a specific "resource value" to it--it can vary from a desert (very few resources) to a jungle (many resources); this resource value is added at a steady state, analogous to an external energy source such as sunlight. These digital organisms compete for this memory space and use it for energy, and to go on "living" they must have enough resources to sustain themselves and their growth." https://lnkd.in/etiQ6T7 View in LinkedIn

LOVING MACHINES. Rasmussen "sees us inventing machines that can "love more deeply" than may be humanly possible." https://lnkd.in/dwADMWc View in LinkedIn
