The Anthropic Cosmological Principle
TLDR
In this article, Barrow and Tipler examined the question of Mankind's place in the universe, taking the reader on a tour of many scientific disciplines and offering fascinating insights into issues such as the nature of life, the serach for extraterrestrial intelligence, and the past history and fate of our universe.Abstract:
Is there any connection between the vastness of the universes of stars and galaxies and the existence of life on a small planet out in the suburbs of the Milky Way? This book shows that there is. In their classic work, John Barrow and Frank Tipler examine the question of Mankind's place in the Universe, taking the reader on a tour of many scientific disciplines and offering fascinating insights into issues such as the nature of life, the serach for extraterrestrial intelligence, and the past history and fate of our universe.read more

Habitable zones in the universe
TL;DR: This work reviews the historical development of the concept of habitable zones, the present state of the research, and suggest ways to make progress on each of the habitable zones and to unify them into a single concept encompassing the entire universe.

New limits on the possible variation of physical constants
TL;DR: In this paper, the frequency of high-redshift hydrogen 21-cm absorption with associated molecular absorption in two quasars was compared to place new (1 sigma) upper limits on any variation in y = g(p) alpha(2) (where alpha is the fine-structure constant, and g (p) is the proton g-factor) of Δ y/y < 5 x 10(-6) at redshifts z = 0.25 and 0.68, these limits are more than an order of magnitude smaller than previous results derived from high

TL;DR: Sponges are highly organized, capable of coordinated re-the genetic structure of populations to the remarkable sponses, and despite the relative simplicity of their body-discoveries of homeotic genes, have major importance in organogenesis in a higher animal.

Possible consequences of absence of "Jupiters" in planetary systems.
TL;DR: The formation of the gas giant planets Jupiter and Saturn probably required the growth of massive ∼ 15 Earth-mass cores on a time scale shorter than the ∼ 107 time scale for removal of nebular gas, but the probability of similar gas giants occurring in other planetary systems is unclear.
