El nuevo hallazgo que derrumba mitos sobre la Isla de Pascua
Un estudio publicado en PLOS ONE acaba de sacudir viejas certezas: la famosa cantera Rano Raraku, donde nacieron más de mil moai, no fue la fábrica centralizada de una élite todopoderosa, sino un entramado horizontal de talleres autónomos. Rapa Nui vuelve a demostrar que las grandes obras humanas también pueden surgir sin jerarquías.

The popularity of breathwork as a therapeutic tool for psychological distress is rapidly expanding. Breathwork practices that increase ventilatory rate or depth, facilitated by music, can evoke subjective experiential states analogous to altered states of consciousness (ASCs) evoked by psychedelic substances. These states include components such as euphoria, bliss, and perceptual differences. However, the neurobiological mechanisms underlying the profound subjective effects of high ventilation breathwork (HVB) remain largely unknown and unexplored. In this study, we investigated the neurobiological substrates of ASCs induced by HVB in experienced practitioners. We demonstrate that the intensity of ASCs evoked by HVB was proportional to cardiovascular sympathetic activation and to haemodynamic alterations in cerebral perfusion within clusters spanning the left operculum/posterior insula and right amygdala/anterior hippocampus; regions implicated in respiratory interoceptive representation and the processing of emotional memories, respectively. These observed regional cerebral effects may underlie pivotal mental experiences that mediate positive therapeutic outcomes of HVB.

Generative artificial intelligence (Gen AI) is transforming the world of creativity, and music is no exception. A study recently published in PLOS One, explores a key question: Can AI-generated music produce the same emotional responses as human-composed music in audiovisual contexts?

Background Chronotype influences risk of depression, with evening-types at higher risk, although the reasons for this are uncertain. Potential mediating factors include mindfulness, sleep quality, rumination, and alcohol consumption, but research is lacking. Methods We explored the role of these factors in the association between chronotype and depressive symptoms amongst young adults, using cross-sectional data collected from a university student sample (N = 546). Results Evening-types had significantly higher levels of depression symptoms, poorer sleep quality, and lower levels of ‘acting with awareness’ and ‘describing’, as well as higher rumination and alcohol consumption. Mediation analyses demonstrated that the link between chronotype and depression was fully mediated by ‘acting with awareness’, ‘describing’, sleep quality, and alcohol consumption. Limitations Only subjective measures were employed, and due to the cross-sectional design, no causal inferences can be made. Conclusion The mediation results shed light on the crucial role of specific mindfulness facets, sleep, and alcohol consumption for explaining why evening types are at higher risk of depression; findings have import for potential interventions aiming to reduce depression risk amongst young adults in particular.
Disappointed in PLOS ONE. Why do they allow this statement, but fail to check if it is actually true?
