A new study in the Journal of Neuroscience reveals how coordinated reactivation across brain regions during sleep helps determine which memory-related neuronal ensembles are preserved over time. By examining rats undergoing fear conditioning, extinction, and retention testing, researchers found that ensembles most engaged in inter-regional coactivation during non-REM sleep were more likely to remain stable days later. The findings point to a systems-level mechanism of memory consolidation, showing that sleep does not simply replay memories but selectively strengthens ensembles embedded in broader network interactions.
A new open-access research article in Neuroscience of Consciousness challenges one of the most widely held assumptions in cognitive science: that computational processes alone can produce consciousness. The study argues that all information inside a computer is intrinsically encoded and requires external decoding to have meaning, making conscious awareness impossible for computational systems. By extending this logic to neural models of the brain, the paper claims consciousness must arise from something beyond computation, redefining how science understands awareness and representation.
A new open-access study in Brain Communications reveals that even low levels of inflammation can alter the neural rhythms that support attention in children and adolescents. Using magnetoencephalography, researchers examined how inflammation markers related to beta and gamma oscillations - core frequencies used by the brain to coordinate top-down control and bottom-up sensory responses. The findings show that inflammation amplifies beta activity while dampening gamma activity across key attention hubs, suggesting reduced neural efficiency during a critical period of cognitive maturation.
A new open-access study in The Journals of Gerontology: Psychological Sciences examines how the emotional symptoms that bridge mood and cognition change across adulthood. Using data from nearly 2,000 participants in the Cambridge Centre for Ageing and Neuroscience, researchers found that dysphoria acts as the main cognitive - affective connector in younger adults, while anhedonia becomes the key bridge in older adults. This age-related shift was tied to differences in gray matter volume, suggesting distinct neurobiological pathways shaping late-life emotional health.
A new open-access study in Nicotine & Tobacco Research offers rare clarity on how e-cigarette use patterns influence smoking cessation. Analyzing data from 886 participants in a large randomized controlled trial, researchers found that non-tobacco flavors were preferred and linked with higher quit success, nicotine strength declined over time, and dual users - those smoking and vaping simultaneously - were more likely to quit later. The results provide practical, evidence-based guidance for clinicians advising smokers who want to quit using e-cigarettes.
A new open-access study in Industrial and Corporate Change examines when entrepreneurial orientation (EO) actually improves innovation performance. Using detailed firm-level data from Korean manufacturing industries, the researchers find that EO's relationship with innovation is not linear but U-shaped: both conservative firms and highly entrepreneurial firms outperform those in the middle. The study also shows that broad external knowledge search weakens this U-shaped pattern, while deep search strengthens it, revealing how managerial attention and external learning strategies shape innovation outcomes.
A new open-access study in the American Journal of Epidemiology examines how memory changes before, during, and after a major financial loss in later life. Using 22 years of data from nearly 15,000 adults in the US Health and Retirement Study, researchers found that individuals who experienced a severe wealth shock - losing 75% or more of household assets within two years - already showed faster memory decline beforehand. They also experienced an acute drop in memory at the moment of loss, followed by slower decline in the years after. These findings highlight the deep cognitive imprint of financial instability.
A new open-access study in the International Journal of Public Opinion Research investigates how social media exposure shapes public fear of civil war across 60 countries. Drawing on nearly 87,000 survey responses from the World Values Survey (2017 - 2022), the analysis shows that people who consume more political information on social media consistently report higher fear of civil conflict, even after accounting for demographics, political attitudes, and alternative explanations. The findings extend classic cultivation theory into the digital age, revealing that online political environments subtly, but systematically, heighten perceptions of societal danger.
A new open-access expert statement in Sexual Medicine from the European Society for Sexual Medicine (ESSM) provides the most comprehensive framework to date on how anxiety manifests in sexual dysfunction. Reviewing nearly two decades of research, the authors identify five distinct forms of anxiety - performance anxiety, sexual phobia, sexual distress, attachment anxiety, and somatic symptom disorder - each with unique features, mechanisms, and clinical implications. Their central message is clear: most patients experience more than one type of anxiety simultaneously, and effective care requires precise, tailored intervention.
