Are we hallucinating or can psychedelic drugs modulate the immune system to control inflammation?

open access: yesBritish Journal of Pharmacology, EarlyView.
Psychedelic drugs that activate 5‐HT2A receptors have been long used for cultural, medicinal and recreational purposes. Interest in psychedelics for treating psychiatric disorders has resurged recently and is well documented; less well recognised are their anti‐inflammatory properties. Growing evidence now demonstrates that psychedelics modulate immune

Experiment on monitoring and early warning of karst collapses based on acoustic emission technology

open access: yesCarsologica Sinica
The karst collapse is a dynamic geological process in which the damage of soil mass and development of cavity ultimately result in the instability of the overburden layer.

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

open access: yesCladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Spatiotemporal evolution of landscape stability in World Heritage Karst Sites: a case study of Shibing Karst and Libo-Huanjiang Karst

open access: yesHeritage Science
Landscape stability is a paramount concern within the field of landscape ecology. Indices of landscape patterns not only facilitate an effective analysis of land use transformations but also delve into the mechanisms of landscape disturbances across ...

Overview on karst geology of Vietnam

open access: yesCarsologica Sinica
Karst is widely distributed in Vietnam, covering almost 60,000 km2, approximately 20% of the total area of Vietnam. Most karst rocks crop out in North and Central Vietnam. Karst developed with peak-clusters, peak-forests, caves, etc.

Assesing the hydrogeological functioning of an evaporite karst system coupling tritium and physicochemical data [PDF]

open access: yes, 2019
Discharge rate, electrical conductivity and water temperature have been continuously recorded in an evaporite karst spring located in S Spain and 3H determinations of spring water were performed.

Scientists’ warning on the global destruction of rock outcrop ecosystems

open access: yesConservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Dissolution process of carbonate rocks by different types of water in atmospheric environment and δ13C evolution of dissolved inorganic carbon

open access: yesCarsologica Sinica
Carbonate dissolution is a geological process that occurs in the shallow surface environment of the Earth. Due to its geochemical characteristics—such as low temperature, openness, sensitivity, and biological participation—it leads to variability in the ...

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

open access: yesGroundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers

open access: yesGroundwater, EarlyView.
Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...
