Research by Marco Del Giudice reveals parasites manipulate host behavior to increase transmission chances and alter neural functioning. Hosts evolve countermeasures to evade manipulation, but these adaptations may also create new vulnerabilities.
An increase in elite Maya's preference for a maize-based diet made the population more vulnerable to drought, contributing to its societal collapse. The study found that a less flexible and less resilient system resulted from population expansion, agricultural intensification, and socially conditioned food preferences.
A new study found that biomedical bleeding can reduce spawning activity and alter biological rhythms in female horseshoe crabs, potentially impacting reproduction and population levels. The research suggests that the recovery from bleeding may also affect energy allocation towards spawning.
Researchers Nicolae Morar and Brendan J. M. Bohannan examine five common conceptual frameworks describing the human microbiome, highlighting their benefits and drawbacks. The study suggests a pragmatic approach considering all metaphors to explore therapies for diseases and disorders.
Sargon II envisioned Karkemish as a royal palace and western capital of Assyria, rebuilding the city with ritual ceremonies. However, his death led to the city's decline and loss of interest from subsequent Assyrian kings.
