摘要:The brown rat (Rattus norvegicus) occupies nearly every terrestrial habitat with a human presence and is one of our most important model organisms. Despite this prevalence, gaps remain in understanding the evolution of brown rat commensalism, their global dispersal, and mechanisms underlying contemporary adaptations to diverse environments. In this Review, we explore recent advances in the evolutionary history of brown rats and discuss key challenges, including finding and accurately dating hi...

摘要:There is an urgent need to develop better treatments for mental health conditions that affect one in every eight people in the world. To combat this concern, psychedelic drugs have been combined with psychotherapy and studied in clinical trials in the United States and Europe. Psychedelics are hallucinogenic drugs that alter brain activity and facilitate altered states of consciousness. The proposed benefits of psychedelic-assisted therapy (PAT) include relatively short treatment times and str...

摘要:For several decades, although studies of rat physiology and behavior have abounded, research on rat emotions has been limited in scope to fear, anxiety, and pain. Converging evidence for the capacity of many species to share others' affective states has emerged, sparking interest in the empathic capacities of rats. Recent research has demonstrated that rats are a highly cooperative species and are motivated by others' distress to prosocial actions, such as opening a door or pulling a chain to ...

摘要:Long noncoding RNAs (lncRNAs) are essential regulatory elements of sex chromosomes that act to equalize gene expression levels between males and females. XIST, RSX, and roX2 regulate X chromosomes in placental mammals, marsupials, and Drosophila, respectively. Because the green anole (Anolis carolinensis) shows complete dosage compensation of its X chromosome, we tested whether a lncRNA was involved. We found an ancient lncRNA, MAYEX, that gained male-specific expression more than 89 million y...

摘要:The selective conversion of polyethylene (PE), polypropylene (PP), and mixtures of these two polymers to form products with high volume demand is urgently needed because current methods suffer from low selectivity, produce large quantities of greenhouse gases, or rely on expensive, single-use catalysts. The isomerizing ethenolysis of unsaturated polyolefins could be an energetically and environmentally viable route to propylene and isobutylene; however, noble-metal homogeneous catalysts and an...
