EMBER-MDD Will Test Multi-Omic Biomarkers for Esketamine Response

TL;DR: A 2026 methodology paper in European Archives of Psychiatry and Clinical Neuroscience describes EMBER-MDD, a research-only multi-omic study designed to find treatment-resistance and esketamine-response biomarkers in about 420 adults with major depressive disorder. Key Findings About 420 adults: EMBER-MDD will analyze biomaterials from approximately 420 adults with major depressive disorder. 210 versus 210 design: …

Antagonistic Relationships Shaped Human Brain Social Maps in fMRI Study

TL;DR: A 2026 study in Communications Psychology used functional MRI (fMRI) before and after a television drama and found that antagonistic relationships were represented most clearly in the left anterior supramarginal gyrus and right medial prefrontal cortex. Key Findings 21 young adults: The study scanned 21 college students before and after they watched a 6-episode …

Dexterous Soft Hand Exoskeleton Restored Grasping in Severe Paralysis

TL;DR: A 2026 study in Nature Machine Intelligence reported that a textile soft hand exoskeleton with thumb control and surface electromyography (sEMG) intent detection restored practical grasping in one person with severe ALS-related hand paralysis and helped the most severely impaired stroke participants more than moderately impaired users. Key Findings 97% intent sensitivity: A non-invasive …

Plasma Vitamin C Linked to Gray Matter and Default Mode Network MRI Measures in 2,044 Older Adults

by
Plasma Vitamin C Linked to Gray Matter and Default Mode Network MRI Measures in 2,044 Older Adults

TL;DR: A 2026 cohort study in PLOS One found that higher fasting plasma vitamin C levels were independently associated with larger MRI-measured gray matter and stronger default mode network (DMN) structural connectivity in 2,044 older adults, but the cross-sectional design cannot show that vitamin C caused the brain differences. Key Findings Large MRI cohort: The …

Childhood Abuse Timing Linked to Hippocampus and Amygdala Emotion Responses

by
Childhood Abuse Timing Linked to Hippocampus and Amygdala Emotion Responses

TL;DR: A 2026 fMRI study in Molecular Psychiatry linked abuse before age 13 to stronger hippocampal responses during non-conscious negative emotion processing, while abuse during adolescence was linked to stronger amygdala responses during conscious emotion viewing. Key Findings Timing split the limbic response: The sample included 635 adults after exclusions and quality checks, including people …

Open-Label Placebo Lowered Stress in Older Adults Over 3 Weeks

TL;DR: A 2026 randomized trial in International Journal of Clinical and Health Psychology found that older adults who knowingly took placebo pills for 3 weeks reported lower stress and performed better on Digit Span than controls. Key Findings Aging trial context: The trial randomized 90 healthy community-dwelling adults in Milan, ages 65 to 90, into …

Pregnancy Accelerometer and Sleep Diary Tracking Was Feasible but Declined Late

by
Pregnancy Accelerometer and Sleep Diary Tracking Was Feasible but Declined Late

TL;DR: A 2026 feasibility study in the Journal of Activity, Sedentary and Sleep Behaviors found that pregnant participants could use a research-grade accelerometer plus text-message sleep diaries across much of pregnancy, although third-trimester wear declined. Key Findings 10 pregnant participants: The pilot recruited Kaiser Permanente Northern California members at 10 weeks’ gestation and followed them …

Postoperative Pain Review Finds NSAID-Dexamethasone and Regional Anesthesia Strongest for Opioid Sparing

by
Postoperative Pain Review Finds NSAID-Dexamethasone and Regional Anesthesia Strongest for Opioid Sparing

TL;DR: A 2026 review in Journal of Pain Research argues that postoperative pain care is moving away from opioid-centered prescribing toward multimodal, opioid-sparing protocols, with the strongest practical signal around NSAIDs paired with dexamethasone or regional anesthesia and the largest unresolved gap after hospital discharge. Key Findings More than 80% affected: The review describes postoperative …

PINK1/Parkin Mitophagy Review Clarified Parkinson Disease Mechanisms

by
PINK1/Parkin Mitophagy Review Clarified Parkinson Disease Mechanisms

TL;DR: A 2026 review in Translational Neuroscience summarizes why PINK1 and parkin, two genes linked to early-onset parkinsonism, keep pointing researchers back to mitophagy and autophagy as Parkinson disease mechanisms. Key Findings 18 PARK loci noted: The review frames familial Parkinson genetics as a route into molecular mechanisms, including PARK2 and PARK6. PARK2 encodes parkin: …

Parasite-Induced Neuroinflammation May Link Infection to Behavior

by
Parasite-Induced Neuroinflammation May Link Infection to Behavior

TL;DR: A 2026 review in the Journal of Neuroinflammation argued that several parasitic infections may affect behavior and cognition through converging microbiota, immune, barrier, and glial pathways. Key Findings Protozoa and helminths reviewed: The review covered neurotropic parasites such as Toxoplasma gondii, Plasmodium species, and Trypanosoma species, plus intestinal and tissue helminths. Five shared pathways: …
