Summary: New research from UCLA shows that listening to music immediately after an experience can change how that event is remembered—boosting detailed recall only when the listener’s emotional arousal is at an optimal, moderate level. In contrast, very strong or very weak emotional reactions to post-event music tend to favor memory for the general gist … Read more

Summary: A new study has identified seven blood metabolites linked to excessive daytime sleepiness (EDS), a common condition affecting roughly one in three Americans. The research points to both dietary and hormonal influences: certain omega-3 and omega-6 fatty acids were associated with lower risk of EDS, while compounds such as tyramine and some hormone-related metabolites … Read more

Summary: A large cross-linguistic study finds a consistent, universal rhythm in human speech: speakers tend to produce prosodic chunks called intonation units roughly every 1.6 seconds. These rhythmic units organize conversation, help listeners follow meaning and turn-taking, and align with slow brain oscillations tied to memory, attention, and voluntary action. Researchers say this regular pacing … Read more

Summary: Chronic pain affects millions worldwide, and current opioid treatments carry high risks of dependence and serious side effects. New research has identified a specific group of neurons in the amygdala that appear to drive the unpleasant, emotional dimension of pain. This discovery is guiding efforts to develop non-opioid drugs that could reduce suffering without … Read more

Summary: Researchers have developed a novel imaging method that reveals how dual agonist drugs such as tirzepatide interact with cells in the pancreas and brain to control blood sugar and appetite. Using fluorescent probes called daLUXendins, the team visualized how these drugs bind to insulin-producing beta cells and other pancreatic cell types, as well as … Read more

Summary: Stress affects everyone, but its impact on the brain depends on the type and duration. A recent rat study shows that brief, acute stress tends to trigger anxiety-like behaviours—particularly in males—while prolonged, unpredictable mild stress is more closely associated with depressive-like symptoms. The research also reveals stress-related changes in blood-brain barrier (BBB) proteins, with … Read more

Summary: A new study from the University of Michigan shows that the brain actively maintains blood glucose stability during ordinary daily conditions, not only during acute crises. Researchers identified a specific set of neurons in the ventromedial hypothalamus—VMHCckbr neurons—that help preserve blood sugar by promoting fat breakdown, particularly during the early hours of sleep. This … Read more

Summary: New research finds that Americans with lower levels of education are experiencing faster biological aging than those with more schooling, and that this gap has widened over the past three decades. Biological age — which gauges internal physiological health rather than simply years lived — indicates that people with a college degree are aging … Read more

Summary: A landmark study overturns a long-held view of brain plasticity by showing that the brain preserves a detailed map of a lost limb for years after amputation. Functional MRI scans taken before and repeatedly after surgery reveal minimal change in cortical activity, even when participants attempted to move individual phantom fingers. Machine learning classifiers … Read more

Summary: A new long-term study in mice finds that continuous oral nicotine intake reshapes metabolism associated with aging and slows age-related motor decline. By acting on a gut-sphingolipid-energy axis, nicotine improved cellular energy balance, reduced harmful lipid buildup, preserved gut microbial diversity, and supported neuromuscular function. These results identify molecular pathways that could inform development … Read more
