TL;DR: A 2026 study in Nature Communications found that in mice, stress from inflammation, forced cell division, cancer-like pressure, and aging activated MLKL in blood-forming stem cells without causing widespread cell death. Instead, active MLKL built up in mitochondria, damaged the cells’ energy machinery, and made the surviving stem cells age faster. Key Findings Several …
TL;DR: A 2026 study in Psychopharmacology found that after 14 days of unpredictable chronic stress, a single 1-hour ayahuasca exposure restored sociability, reduced anxiety-like behavior, normalized cortisol, and rescued whole-brain BDNF in adult zebrafish within 24 hours. Key Findings 396 fish across 6 groups: Adult zebrafish were split into stressed and non-stressed groups, then exposed …
TL;DR: A 2026 MRI study in Brain Imaging and Behavior of 136 healthy young adults found no robust whole-brain gray matter, white matter, cortical thickness, or brain-age differences between early and late chronotypes. Key Findings 136 young adults: The study compared 68 early chronotypes with 68 late chronotypes. No robust whole-brain VBM differences: Voxel-based gray …
TL;DR: A 2026 preprint UK Biobank neuroimaging study in medRxiv found that the comorbidity group showed widespread lower cortical volume, subcortical differences, and white matter microstructure alterations, while several alterations appeared unique to the chronic pain-depression comorbidity group. Key Findings Evidence map: a cross-sectional neuroimaging analysis comparing comorbid chronic pain and depression with pain-only, depression-only, …
TL;DR: A 2026 preprint birth-cohort study in medRxiv found that 91.1% of children had experienced violence by age 8, while age-8 violence exposure was associated with higher internalizing, externalizing, total problem scores, and disorder odds. Key Findings Evidence map: a South African birth-cohort analysis using violence reports and child mental health assessment. Study group: 974 …
TL;DR: A 2026 BMC Medicine study of UK Biobank adults linked adversity in both childhood and adulthood to higher frailty, older metabolomic age profiles, lower grip strength, and some telomere differences, with the clearest associations in people reporting multiple adverse events. Key Findings Large cohort: The study analyzed up to 153,557 middle-aged and older UK …
TL;DR: A 2026 cohort study in BJPsych Open found that childhood attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) difficulties predicted poorer young-adult outcomes, but rare copy number variants (CNVs), which are deleted or duplicated DNA segments, did not clearly sharpen that prognosis. Key Findings 8,414 young people had CNV data: Researchers analyzed genetic and …
TL;DR: A 2026 review in Reviews in the Neurosciences argues that chemotherapy-induced peripheral neurotoxicity (CIPN), nerve injury from cancer treatment, can involve central nervous system changes that help explain chronic neuropathic pain and chemotherapy-related cognitive impairment. Key Findings 70-80% during treatment: The review cites chemotherapy-induced peripheral neurotoxicity as affecting about 70-80% of patients during treatment. …
TL;DR: A 2026 methods paper in Nature Neuroscience introduced Cheese3D, a six-camera system that tracked whole-mouse-face movement in 3D at sub-millimeter precision and used facial dynamics to infer anesthesia depth and neural-state-linked expression. Key Findings Sub-millimeter 3D tracking of the whole mouse face: Cheese3D uses a calibrated 6-camera array to capture motion of ears, eyes, …
TL;DR: A 2026 systematic review in European Archives of Psychiatry and Clinical Neuroscience argues that catatonia, a syndrome of freezing, mutism, and abnormal movement, may involve underweighted limbic-system circuitry linking emotional regulation with motor shutdown. Key Findings Limbic system has been comparatively underexplored in catatonia neurobiology: Most prior models focused on cortical motor systems and …
