Natural Daylight During Office Hours Improved Glucose Time-in-Range and Shifted Substrate Metabolism in Type 2 Diabetes

Natural Daylight During Office Hours Improved Glucose Time-in-Range and Shifted Substrate Metabolism in Type 2 Diabetes

TL;DR: A 2026 randomized crossover trial in Cell Metabolism compared natural daylight against standard artificial office lighting in 13 older adults with well-controlled type 2 diabetes and found that natural-daylight days produced more time in a healthy blood-glucose range (about 51% vs 43%), smaller glucose swings, and a metabolic shift toward burning more fat and …

Three or More Live Births Was the Only Reproductive Factor Linked to Lower Stroke Risk in Framingham Women

Three or More Live Births Was the Only Reproductive Factor Linked to Lower Stroke Risk in Framingham Women

TL;DR: A 2026 study in the Journal of the American Heart Association followed 1,882 stroke-free women from the Framingham Heart Study for a median of 18 years and found that having three or more live births was associated with a reduced risk of clinical stroke and lower MRI markers of vascular brain injury — the …

Lower-Body Cues Matched Whole-Body Accuracy in Female Body Size Judgments

Lower-Body Cues Matched Whole-Body Accuracy in Female Body Size Judgments

TL;DR: A 2025 study in BMC Biology found that people judged female body size about as accurately from lower-body images as from whole-body images, but isolated thigh regions alone were not enough. Key Findings Two body-perception experiments: Researchers tested 99 participants in Experiment 1 and 116 participants in Experiment 2 using a bodyline task. Lower-body …

Acute and Post-Acute Settings Initiated Most Cognition-Altering Prescriptions in Older Adults With Dementia

Acute and Post-Acute Settings Initiated Most Cognition-Altering Prescriptions in Older Adults With Dementia

TL;DR: A 2026 study in JAMA Network Open analyzed Medicare claims for adults 66+ from 2008 to 2021 and found that cognition-altering medications — antipsychotics, benzodiazepines, hypnotics, anticholinergics — were disproportionately initiated in emergency rooms, hospitals, and skilled nursing facilities rather than doctors’ offices, especially in dementia patients (43% of antipsychotic starts vs 22% of …

Children and Adolescents With ADHD Had Roughly 6x the Depression Rate of Peers in 24-Study Meta-Analysis

Children and Adolescents With ADHD Had Roughly 6x the Depression Rate of Peers in 24-Study Meta-Analysis

TL;DR: A 2025 meta-analysis in the Journal of Attention Disorders pooled 24 studies (N=6,815) and estimated that 11.31% of children and adolescents with ADHD had co-occurring depression — about six times the rate seen in neurotypical peers in head-to-head case-control studies (~12% vs ~2%). Key Findings Pooled depression rate of 11.31% across 24 studies: The …

Intestinal Epithelial Serotonin Reduced Anxiety and Depression-Like Behavior via Vagus in Mice; In Utero SSRI Linked to Infant Constipation

Intestinal Epithelial Serotonin Reduced Anxiety and Depression-Like Behavior via Vagus in Mice; In Utero SSRI Linked to Infant Constipation

TL;DR: A 2024 Gastroenterology study found that intestinal epithelial serotonin reduced anxiety- and depression-like behavior in mice through vagal signaling, while prenatal SSRI exposure in a human cohort predicted infant functional constipation independent of maternal depression. Key Findings Gut-only serotonin reuptake transporter ablation reduced anxiety and depression-like behavior: Targeting SERT only in the intestinal epithelium …

Ex-Smokers Had Higher Food Cue Reactivity on fMRI

Ex-Smokers Had Higher Food Cue Reactivity on fMRI

TL;DR: A 2026 medRxiv preprint found that ex-smokers had higher fMRI blood oxygen level dependent (BOLD) responses to high-energy food pictures than adults with obesity or abstinent alcohol dependence, suggesting a brain reward route for post-quitting weight gain. Key Findings 77-person fMRI comparison: Researchers compared 25 ex-smokers, 26 abstinent adults with alcohol dependence, and 26 …

Early-Life Visceral Stress Sensitized Auditory Brainstem and Altered Cochlear Proteome in Rat IBS Model

Early-Life Visceral Stress Sensitized Auditory Brainstem and Altered Cochlear Proteome in Rat IBS Model

TL;DR: A 2026 rat study in Neurobiology of Stress found that early-life visceral stress produced adult IBS-like symptoms alongside auditory brainstem sensitization and cochlear protein changes, giving a mechanistic explanation for sound sensitivity reported by some IBS patients. Key Findings Early-life visceral stress sensitized the auditory brainstem: Rats exposed to early-life visceral stress (the standard …

Braless State Increased Attractiveness Ratings but Lowered Faithfulness Ratings

Braless State Increased Attractiveness Ratings but Lowered Faithfulness Ratings

TL;DR: A 2026 study in Frontiers in Psychology found that braless images were rated as more attractive but less faithful, while women who feared sexual harassment reported being less likely to go braless in public. Key Findings 409 Slovak women surveyed: Researchers asked women about bra wearing in public and private settings, body-related factors, sexual …

Big Five Personality Traits Predicted Sexual Fantasy Frequency

Big Five Personality Traits Predicted Sexual Fantasy Frequency

TL;DR: A 2026 study in PLOS One found that Big Five personality traits were linked to how often 5,225 partnered adults reported sexual fantasies: conscientiousness and agreeableness predicted lower fantasy frequency, while the depression facet of negative emotionality predicted higher frequency. Key Findings Partnered adult sample: researchers surveyed 5,225 partnered adults recruited through Qualtrics Panels, …
