Neurons Must Break Their Own DNA to Build the Brain: Topoisomerase IIβ-Catalyzed Double-Strand Breaks as a Gating Mechanism for Activity-Dependent Gene Expression
颠覆性发现：神经元必须主动断裂DNA才能构建大脑——拓扑异构酶IIβ介导的即时早期基因表达机制
Harvard and MIT researchers reveal that neuronal activation requires transient, topoisomerase IIβ-mediated DNA double-strand breaks at specific promoter regions to relieve topological constraints and initiate immediate early gene expression—a process whose dysregulation underlies neurodevelopmental disorders and age-related cognitive decline.
Not All Aging Is Decline: Yale Longitudinal Data Shows Nearly Half of Older Adults Exhibit Improved Cognitive and Psychological Resilience
耶鲁大学追踪研究：近半数中老年人在认知与心理韧性上随龄改善，揭示“成功老化”的神经与代谢基础
Yale longitudinal data reveals that nearly half of older adults demonstrate significant improvements in cognitive and psychological functioning over time, challenging the linear decline paradigm and identifying neurobiological and metabolic correlates of successful aging.
The Dual-Processor Brain: How Neural Circuit Rewiring Enables True Multitasking
大脑多任务处理并非神话：科学家揭示神经“双处理器”同步重连机制
New research from Harvard and Stanford shows the brain achieves true multitasking not by parallel processing, but by dynamically rewiring dual circuits for near-instantaneous task switching.
The Midlife Breaking Point: Accelerated Biological Aging and Systemic Vulnerability in U.S. Adults Aged 40–60
中年危机并非心理问题：美国中年人生物年龄加速与系统脆弱性的实证分析
A data-driven analysis of why U.S. middle-aged adults exhibit accelerated biological aging, linking metabolic dysfunction, chronic low-grade inflammation, and telomere attrition to a systemic “breaking point” before age 60.
Dreams Are Not Noise: How the Sleeping Brain Rewrites Reality to Fortify Cognition
梦境并非随机：大脑在睡眠中重写现实，构建认知韧性
This paper synthesizes recent peer-reviewed evidence from Harvard, Stanford, and *Nature Neuroscience* to demonstrate that dreams are a non-random, active neurobiological process of memory reclassification, emotional desensitization, and cognitive map reconstruction.
Neural Plasticity Without Expiration: Neurobiological Mechanisms and Practical Protocols for Cognitive Improvement Into the Tenth Decade of Life
大脑可塑性没有“截止日期”：90岁后仍可显著改善认知功能的神经机制与实操方案
A longitudinal cohort study of 1,440 nonagenarians demonstrates that targeted cognitive training combined with metabolic optimization can reverse age-related white matter degradation and improve executive function well into the 10th decade.
Predictive Not Prewired: A Bayesian Sensorimotor Reappraisal of Speech Learning in the Adult Brain
颠覆性发现：言语学习并非依赖“先天语法”，而是基于感官运动预测的贝叶斯脑机制
A new neuroimaging study overturns the classical “language organ” model, showing that adult speech learning relies on real-time prediction error signals between motor and auditory cortices, not innate grammatical modules.
Prion-like Propagation of α-Synuclein via Tunneling Nanotubes: A Mechanistic Breakthrough from Yale in Parkinson’s Disease Progression
帕金森病脑内扩散的分子机制：耶鲁团队揭示α-突触核蛋白“隧道”传播路径
Yale researchers identify tunneling nanotubes as the direct intercellular route for α-synuclein transfer, explaining the stereotypical spread of Parkinson’s pathology along neural circuits.
A Silent Gene Speaks: The Molecular Etiology of a Rare Neurological Disorder Finally Explained
被遗忘的基因：揭开一种罕见神经疾病的分子病因
A study published in *Nature Neuroscience* identifies a previously overlooked recessive gene mutation that disrupts the endoplasmic reticulum–mitochondria axis, providing the long-sought molecular cause of a rare neurodegenerative disorder.
A Widely Used Brain Health Supplement Is Associated with Reduced Lifespan in Men: A Systematic Review of Clinical and Mechanistic Evidence
流行脑部补充剂与男性寿命缩短的关联：一项基于临床与流行病学证据的系统性风险分析
This review demonstrates that a popular over-the-counter brain supplement is significantly linked to increased all-cause mortality in men, driven by mechanisms involving mitochondrial stress and epigenetic dysregulation.
Autophagy and Longevity: A Precision Protocol for AMPK-mTOR Pathway Activation Through Daily Practices
细胞自噬与延缓衰老的日常实践：基于AMPK-mTOR通路的精准激活方案
This paper reviews the molecular mechanisms of autophagy and presents a daily protocol combining intermittent fasting, exercise, and natural compounds to activate AMPK-mTOR pathways for longevity.
Circadian Resynchronization: The Molecular Logic of Light–Microbiome Crosstalk in Sleep Architecture Repair
昼夜节律重塑：光信号与肠道微生物协同调控睡眠修复的分子逻辑
Drawing on recent clinical data from Harvard and Stanford, this paper reveals how photoperiod and gut microbiota synergistically repair deep sleep via the melatonin–short-chain fatty acid axis, and provides actionable circadian reset protocols.

深度睡眠的“代谢开关”：科学家揭示同步增肌、燃脂与脑修复的神经回路
This paper reviews a recently identified brainstem-to-cortex circuit that, during slow-wave sleep, simultaneously triggers muscle protein synthesis, adipose tissue lipolysis, and glymphatic clearance of neurotoxic metabolites.
The Metabolic Gating of Sleep: How Chronobiology and NAD+ Precursors Synergistically Restore Deep Sleep Architecture
昼夜节律的“代谢开关”：NMN与时间生物学如何协同修复深度睡眠
A mechanistic review of how the circadian clock gates mitochondrial autophagy via NAD+/SIRT1, and a time-restricted intervention protocol to restore slow-wave sleep.
The Microglial Lipid Catabolism Collapse Hypothesis: A Mechanistic Reappraisal of Alzheimer’s Disease Initiation
阿尔茨海默病的真正起点：小胶质细胞脂质代谢崩溃假说的临床验证
A newly identified mechanism suggests Alzheimer's disease is triggered not by amyloid-beta accumulation, but by an age-related loss of a specific lipid-processing enzyme in microglia, initiating a cascade of neuroinflammation and tau pathology.
