Psychedelics and Cognition: A New Look

A recent renaissance in psychedelic research investigates the cognitive effects of these drugs, shifting from mathematical modeling to behavioral and clinical studies. Studies have found that psychedelics can increase spontaneous creative insights while decreasing task-specific creativity, as well as affect memories in a malleable way.

New articles for Geosphere posted early online

Two new studies examine the Late Triassic tectonic stress field of the southwestern Ordos Basin and its implications for regional geology. The research also explores a new Cambrian stratigraphic unit in the Grand Canyon, USA, and the progressive unroofing of the Big Maria and Riverside Mountains in southeastern California.

Climate change threatens lemurs on Madagascar

A study published in PNAS found that climate change is destabilizing mouse lemur populations on Madagascar, increasing their risk of extinction despite high reproductive output. The data analysis revealed opposing trends of rising mortality and reproductive rates, which have prevented population collapse but accelerated the life cycle.

NIH researchers discover new autoinflammatory disease, suggest target for potential treatments

Scientists have identified an autoinflammatory disease called Lyn kinase-associated vasculopathy and liver fibrosis (LAVLI) linked to mutations in the LYN gene. The research suggests that Lyn kinase may be a potential therapeutic target for drugs treating non-syndromic small vessel vasculitis and inflammation-induced liver fibrosis.

How to prepare for ocean acidification, a framework

An international research team has developed a framework to evaluate government preparedness for ocean acidification, a pressing threat to marine ecosystems. The framework identifies six aspects of effective policy and specific indicators, enabling policymakers to assess their own preparedness and identify areas for improvement.

Highly charged ions melt nano gold nuggets

Scientists at TU Wien have developed a technique to control the shape and size of nano gold structures using highly charged ions. The experiment shows that the impact force is not the decisive factor, but rather the electrical charge of the ions, which deposits energy at the point of impact and disrupts the crystal structure of the gold.
