In this paper, we consider a version of the Hayden–Preskill thought experiment in which message thrown into black hole is itself smaller hole. We then discuss implications existence recovery channel for at asymptotic infinity, resulting sharpening information paradox observers who never need to approach horizon. suggest decoherence mechanisms as way resolving sharpened paradox.

Archaeological landscapes of colonial encounter were shaped to varying degrees by mutual mistrust, misunderstanding, anxiety, and the inherent terror frontier violence. In mission encounters Island Melanesia, trope “cannibalism” added a particular tinge these fears colonized other. Mythologies cannibalism both repulsed motivated Christian missionaries who led places such as Erromango in New Heb...

Mortality due to cannibalism is a major problem in laying hens. Due to prohibition of beak-trimming in the European Union, this problem will increase in the near future. One solution to reduce mortality due to cannibalism is to use genetic selection. Mortality due to cannibalism, however, differs from conventional breeding traits, because it depends on social interactions among individuals. Sel...

The abundance of sperm relative to eggs selects for males that maximize their number of mates and for females that choose high quality males. However, in many species, males exercise mate choice, even when they invest little in their offspring. Sexual cannibalism may promote male choosiness by limiting the number of females a male can inseminate and by biasing the sex ratio toward females becau...

Recent analyses of prehistoric multiple inhumations in Anasazi sites in the American Southwest have argued that cannibalism best explains evidence of defleshing, cutting, and bone breakage. The validity of this explanation is questioned in a review of ethnohistoric and ethnographic literature on Pueblo witchcraft and witch execution. A model based on Puebloan procedures for witch destruction is...

Evolutionary theory predicts that alternative trophic morphologies are adaptive because they allow a broad use of resources in heterogeneous environments. The development of a cannibal morphology is expected to result in cannibalism and high individual fitness, but conflicting results show that the situation is more complex. The goal of the present study was to increase our understanding of the...

Swarming and mass migration are spectacular and sometimes devastating features of the biology of various animal species. These phenomena are typically associated with actual or anticipated depletion of food resources after an increase in population density, but the mechanisms driving such collective movements are poorly understood. Here we reveal that insects in large, coordinated migratory ban...

Trophic cascades are often a potent force in ecological communities, but abiotic and biotic heterogeneity can diffuse their influence. For example, inducible defenses in many species create variation in prey edibility, and size-structured interactions, such as cannibalism, can shift predator diets away from heterospecific prey. Although both factors diffuse cascade strength by adding heterogene...
