NOMENCLATURE CHANGE. “No longer would the term adaptive enzyme be used, for the term "adaptive" denoted a change which increased the evolutionary fitness of the organism. Rather, the process would be known as enzyme induction and "any substance thus inducing enzyme synthesis is an enzyme 'inducer.' An enzyme-forming system which can be so activated by an exogenous inducer is 'inducible'.” https://lnkd.in/dQuxg6Y View in LinkedIn

IMPACT OF COMPETITION FOR RESOURCES. “This would lead to the canalization of development and would explain the stability and irreversibility of differentiation. This is what Spiegelman had also noted. Waddington noted that others such as Darlington, Lindegren, Spiegelman, and Sonneborn, have proposed such self-duplicating plasmagenes on genetic evidence, but that this type of entity fit in well with the observed facts of embryology.” https://lnkd.in/dQuxg6Y View in LinkedIn

COMPETITION FOR RESOURCES. “In such circumstances, comparatively slight changes in the available raw materials might shift the whole dynamic system from one path into another. The progressive substrate changes would lead to changes in new enzyme synthesis, which would, in turn, create further substrate changes.” https://lnkd.in/dQuxg6Y View in LinkedIn

The fertilized gynaecium has metamorphosed into the specks of the next generation; plants never stop working. View in LinkedIn

THE GREAT UNDOCUMENTED KINGDOM. “All the viruses in the ocean end-to-end would stretch further than the nearest 60 galaxies.” They produce half of Earth’s oxygen, and microbial life (mostly viruses) is 96% by weight of all oceanic life, far exceeding the larger creatures. They are also the largest pool of genetic novelty on Earth. Lovely article. https://lnkd.in/d-nEKzQ View in LinkedIn

FAIRGROUND WARPED MIRRORS. “This result means that two ostensibly very different theories--not even acting in spaces of the same dimension--are equivalent. Creatures living in one of these universes would be incapable of determining if they inhabited a 5-D universe described by string theory or a 4-D one described by a quantum field theory of point particles.” https://lnkd.in/draqjTW View in LinkedIn

THE BOUNDARY AT INFINITY. “Thus, the full majesty of superstring theory in an antide Sitter universe is painted on the boundary of the universe.” https://lnkd.in/draqjTW View in LinkedIn

REVISED VIEW OF SPACETIME. “Using antide Sitter spacetime, theorists have devised a concrete example of the holographic principle at work: a universe described by superstring theory functioning in an antide Sitter spacetime is completely equivalent to a quantum field theory operating on the boundary of that spacetime.” https://lnkd.in/draqjTW View in LinkedIn

SWITCHEROO. “Now, if the repulsive cosmological constant is replaced by an attractive one, de Sitter's solution turns into antide Sitter spacetime, which has equally as much symmetry. More important for the holographic concept, it possesses a boundary, which is located at infinity and is a lot like our everyday spacetime.” https://lnkd.in/draqjTW View in LinkedIn

A CHANGING UNIVERSE. “De Sitter spacetime is empty, expands at an accelerating rate and is very highly symmetrical. In 1997 astronomers studying distant supernova explosions concluded that our universe now expands in an accelerated fashion and will probably become increasingly like a de Sitter spacetime in the future.” https://lnkd.in/draqjTW View in LinkedIn
