RECOMMENDATIONS. “NASA and the NSF should welcome proposals to pursue all of these avenues and more as part of its search for life in the universe. The most natural places for these efforts is alongside searches for biosignatures under the umbrella of astrobiology, but since some SETI avenues will employ methods, like high resolution radio astronomy, that are somewhat foreign to that field, SETI work should not be ​restricted​ to that domain.” https://lnkd.in/djnMhU6 View in LinkedIn

SIMPLY GET ON WITH IT. “The best way to develop SETI as a field is to actually practice it, including the development of SETI-specific instrumentation, and innovative uses of new astronomical facilities.” https://lnkd.in/djnMhU6 View in LinkedIn

THE STUBBORN ILLUSION. “People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion.”" "Albert Einstein View in LinkedIn

INTERNAL CLOCK OF TREES. "Endogenous rhythmic growth in oak trees is regulated by internal clocks rather than resource availability. The results indicate that rhythmic growth involves dramatic oscillations in plant metabolism and gene regulation between below- and above-ground parts. Ectomycorrhizal symbiosis may play a previously unsuspected role in smoothing these oscillations without modifying the rhythmic growth pattern." https://lnkd.in/ds4PhA9 View in LinkedIn

CONTROL LOOPS. “The clock appears thus far to be considerably conserved with the rest of the plant kingdom. Thanks to molecular studies, and the use of circadian reporter systems, we know that the central oscillator consists of three interlocking auto-regulatory transcriptional feedback loops.” https://lnkd.in/dyrdvNg View in LinkedIn

MASSIVE IMPACT IN PLANTS. “In plants, circadian rhythmicity is widespread; a transcriptional circadian cycling has been reported in a range of diverse species, including the model plant Arabidopsis thaliana in which the clock has been well characterized. Approximately one-third of the Arabidopsis transcriptome shows circadian oscillations in abundance when in free-run conditions, indicating direct or indirect circadian control.” https://lnkd.in/dyrdvNg View in LinkedIn

OSCILLATOR HIERARCHIES. “The circadian system of mammals is composed of a hierarchy of oscillators that function at the cellular, tissue and systems levels. A common molecular mechanism underlies the cell autonomous circadian oscillator throughout the body, yet this clock system is adapted to different functional contexts.” https://lnkd.in/dBQ96E6 View in LinkedIn

HUMAN LARKS AND OWLS. “Human subjects can be divided into different chronotypes ranging from very early active “larks” to very late active individuals “owls”. These studies have revealed two unexpected, if not shocking aspects of circadian rhythmicity. First, extreme larks and owls hardly overlap with regard to their sleep-wake cycles. Second, the chronotype changes significantly during the lifetime of an individual.” http://www.smw.ch/content/smw-2014-13984/ View in LinkedIn
