The temporal aspect of the drake equation and SETI.
It is shown that the Drake equation tacitly relies on unverified assumptions on both the physicochemical history of the authors' galaxy and the properties of advanced intelligent communities to form prerequisites for quantification of therake equation parameters.
It is shown that investigations in the field of microwave resonance stimulation of the acupuncture system, as well as investigations of the interactions of consciousness with microscopic and

Against the Empire
It is argued that the "generic" evolutionary pathway of advanced technological civilizations are more likely to be optimization-driven than expansion-driven, in contrast to the prevailing opinions
Kardashev's Classification at 50+: A Fine Vehicle with Room for Improvement
We review the history and status of the famous classification of extraterrestrial civilizations given by the great Russian astrophysicist Nikolai Semenovich Kardashev, roughly half a century after it
Fermi's Paradox - The Last Challenge For Copernicanism?
We review Fermi's paradox (or the 'Great Silence' problem), not only arguably the oldest and crucial problem for the Search for ExtraTerrestrial Intelligence (SETI), but also a conundrum of profound
Anthropic Shadow: Observation Selection Effects and Human Extinction Risks
A significant practical consequence of taking anthropic biases into account in deriving predictions for rare stochastic catastrophic events is described, and some directions for future work are suggested.
