The emergence of life based on amino acid and RNA/ DNA on an Earth type planet requiers a quite narrow parameter space of many of the planet's physical parameters, most important are its mass and temperature conditions. ... The period, more or less, is conserved for the giant planets.) ... Thus, the mass of a terrestrial planet suitable for the advent of the LANA should be close to 5*10 27 g. The same value follows from quite a different condition: the planetary atmosphere should be retained. ...

Insights & Perspectives Think again Targeting cancer's weaknesses (not its strengths): Therapeutic strategies suggested by the atavistic model Charles H. Lineweaver1)*, Paul C. W. Davies2) and Mark D. Vincent In the atavistic model of cancer progression, tumor cell dedifferentiation is interpreted as a reversion to phylogenetically earlier capabilities. The more recently evolved capabilities are compromised first during cancer progression. ... Our most detailed example involves the immune system. ...
