PRINCIPLE VIOLATED. “While this behavior of the entanglement entropy of evaporating black holes violates the holographic principle as it relates to black hole horizons, there is no conflict with the Bousso covariant entropy bound that Bousso used to motivate the holographic principle.” https://lnkd.in/dUKnus8 View in LinkedIn

THE CONUNDRUM. “The evolution of sperm modification by Wolbachia poses an evolutionary puzzle—the trait is only expressed in males and yet symbionts in males are not passed on to the next generation. In randomly mating populations, it will be at best selectively neutral.” https://lnkd.in/dXjWp9f View in LinkedIn

COEVOLUTION. “As Wolbachia genomes often carry divergent cif homologs, the absence of recombination between these genes is compatible with recombination being constrained by selection. This can be explained by the coevolution of binding affinities between the proteins encoded by cifA and their cognate cifB gene.” https://lnkd.in/dXjWp9f View in LinkedIn

ROLE OF RECOMBINATION. “Whether recombination itself created these incompatibilities or whether crossing types arose due to sequence divergence following recombination is unknown. We found that recombination is frequent across the cif gene phylogeny, but it almost exclusively occurs between related syntenic cifA–cifB gene pairs within the same Type.” https://lnkd.in/dXjWp9f View in LinkedIn

RECOMBINATION. “Despite this, clear evidence of recombination has been observed among cif genes from wPip, which infects C. pipiens mosquitoes. wPip strains can carry multiple copies of Type I cif genes, and recombination between closely related paralogs correlates with different CI crossing types.” (CI = cytoplasmic incompatibility). https://lnkd.in/dXjWp9f View in LinkedIn
