Microbial Evolution: Towards Resolving the Plasmid Paradox
نویسندگان
چکیده
Plasmids play a key role in bacterial evolution by providing bacteria with new and important functions, such as antibiotic resistance. New research shows how bacterial regulatory evolution can stabilize bacteria-plasmid associations and catalyze evolutionary innovation.

Unitary solution to a quantum gravity information paradox
We consider a toy model of the interaction of a qubit with an exotic space-time containing a timelike curve. Consistency seems to require that the global evolution of the qubit be nonunitary. Given that quantum mechanics is globally unitary, this then is an example of a quantum gravity information paradox. However, we show that a careful analysis of the problem in the Heisenberg picture reveals...
متن کاملFair-balance paradox, star-tree paradox, and Bayesian phylogenetics.
The star-tree paradox refers to the conjecture that the posterior probabilities for the three unrooted trees for four species (or the three rooted trees for three species if the molecular clock is assumed) do not approach 1/3 when the data are generated using the star tree and when the amount of data approaches infinity. It reflects the more general phenomenon of high and presumably spurious po...
متن کاملPlasticity and Nativism: Towards a Resolution of an Apparent Paradox
Recent research in brain development and cognitive development leads to an apparent paradox. One set of recent experiments suggests that infants are well-endowed with sophisticated mechanisms for analyzing the world; another set of recent experiments suggests that brain development is extremely flexible. In this paper, I review various ways of resolving the implicit tension between the two, and...
متن کاملVariational optimization of probability measure spaces resolves the chain store paradox
In game theory, players have continuous expected payoff functions and can use fixed point theorems to locate equilibria. This optimization method requires that players adopt a particular type of probability measure space. Here, we introduce alternate probability measure spaces altering the dimensionality, continuity, and differentiability properties of what are now the game’s expected payoff fu...
