          Neural Flexibility: Prioritizing Memories to Guide Behavior

          Male worms can activate two conflicting memories—mating and starvation—when encountering the same odor, but only one influences their behavior.

          How Decision-Making Improves with Age

          Adolescents are known for making less optimal, noisy decisions, but a recent study reveals that these tendencies decrease with age and are linked to improvements in complex decision-making skills. Researchers found that decision noise, or variability in choices, mediates age-related gains in goal-directed behaviors and adaptability.

          Brain Circuits Behind Psychedelics’ Anti-Anxiety Power Decoded

          New research has identified distinct neural circuits for the anti-anxiety and hallucinogenic effects of psychedelics. Using the psychedelic DOI in mice, researchers demonstrated that anxiety reduction persists long after hallucinatory effects subside.

          How young people use social media impacts their mental health more than how much time they spend on it. Researchers found that reducing harmful comparisons and fostering meaningful connections online can improve mental well-being, reducing loneliness, anxiety, and depression.

          “Lifesaving” Low-Dose Ketamine Unlocks Rapid Relief for Depression

          Researchers have identified how low-dose ketamine alleviates depression by selectively targeting specific NMDA receptors in the brain. Unlike high-dose anesthetic effects, low-dose ketamine binds to lateral grooves on NMDA receptors, enhancing excitatory transmission and long-term synaptic changes.

          Beer Drinkers Have Poorer Diets, Lower Activity Levels

          Beer-only drinkers have the lowest diet quality, highest caloric intake, and lowest physical activity levels compared to those who drink wine, liquor, or a combination. Researchers analyzed over 1,900 U.S. adults and found beer drinkers scored lowest on the Healthy Eating Index, while wine drinkers scored highest.

          Microbial Load, Not Disease, Shapes Gut Microbiome Signatures

          A new study reveals that changes in gut microbial load, influenced by factors like diet, age, and antibiotics, drive the presence of bacteria previously linked to diseases such as inflammatory bowel disease and colorectal cancer. Using a machine learning model, researchers found that microbial load variations explained bacterial signatures in patients' microbiomes more strongly than the diseases themselves.

          Traditional Paranormal Beliefs Linked to Stress

          Traditional paranormal beliefs, such as witchcraft and religious superstition, are linked to higher stress and reduced coping ability, while new age beliefs, like spiritualism and precognition, show no such link. Researchers used an improved scale to analyze responses from over 3,000 participants, revealing that traditional beliefs may reflect anxieties about external control. The findings highlight the psychological differences between belief types but cannot confirm cause-and-effect relationships.

          Study Revolutionize Restless Legs Syndrome Treatment

          Researchers released new clinical guidelines for treating restless legs syndrome (RLS), emphasizing patient-centered care and evidence-based updates. Iron supplementation is now a key recommendation, addressing low brain iron as a cause of RLS. Dopamine agonists like pramipexole and ropinirole are de-emphasized due to risks of worsening symptoms, while newer treatments such as alpha-2-delta ligands, nerve stimulation, and low-dose opioids gain conditional or strong recommendations.

          Metabolic Pathways Link Cannabis to Psychosis in Teens

          A study investigated how cannabis use influences metabolomic patterns linked to psychotic-like experiences in adolescents. Blood samples revealed that non-cannabis users showed inflammatory metabolic changes associated with hallucinations, while cannabis users exhibited shifts in energy-related metabolites tied to brain ketogenesis. These findings suggest that cannabis use may trigger distinct molecular pathways in psychotic-like experiences.
