Age-related changes in brain network connectivity and cognitive decline A systematic review of resting-state functional brain networks across the adult lifespan shows that older adults exhibit reduced within-network and increased between-network functional connectivity, along with lower segregation, modularity, and efficiency.…
Novel dietary compound enhances stroke therapy by targeting platelets The study explores how sulforaphane (SFN), a compound found in broccoli, selectively inhibits platelet activity without increasing bleeding risks. SFN covalently modifies specific proteins in platelets, notably PDIA6, which affects platelet…
Researchers have identified a gene variant, ADRB1, that may contribute to increased anxiety levels. This variant affects the brain’s adrenergic system, which plays a role in the body’s fight-or-flight response. Understanding the genetic basis of anxiety could lead to more…
Song lyrics have become simpler, more repetitive, and more negative over the last five decades A comprehensive study has found that song lyrics in Western popular music have become simpler, more repetitive, and more negative over the last five decades.…
A new study from the University of Bath has found that cannabidiol (CBD) products do not provide effective relief for chronic pain and could potentially be harmful. This comprehensive review analyzed data from a wide range of clinical trials and…
Genetic predictors of intelligence linked to liberal political beliefs A study investigated the relationship between intelligence and political beliefs using data from over 300 biological and adoptive families. It found that both measured IQ and polygenic scores, which are DNA-based…
Lidocaine’s potential role in treating head and neck squamous cell carcinoma Lidocaine, a common local anesthetic, has been found to induce apoptosis in head and neck squamous cell carcinoma (HNSCC) by activating the bitter taste receptor T2R14. This activation triggers…
Recent research using data from the Behavioral Risk Factor Surveillance System (BRFSS) suggests that non-medical cannabis use in adults aged 45 and older may be associated with decreased odds of subjective cognitive decline (SCD). The study found that non-medical cannabis…
Creative flow, a state where individuals become fully immersed and lose track of time during creative tasks, is linked to specific brain activity patterns. Neuroscientists have discovered that during this state, certain brain regions, such as the prefrontal cortex, exhibit…
