Clearing Senescent Cells Restores Aged Muscle Recovery
Aging muscle struggles to recover after inactivity partly because senescent cells accumulate in the muscle niche. In aged mice, clearing these cells reduced inflammation, improved muscle regeneration, and restored strength after disuse. #Aging #MuscleHealth #Senescence @WuTsaiAlliance https://t.co/yq8Uss9IbZ
Sleep Deprivation Disrupt
Sleep loss reshapes not only the brain, but also the chemistry of the gut–microbiome axis. Restricted sleep disrupted daily rhythms of microbial metabolites in human blood—including butyrate and indole-3–propionic acid—linking poor sleep to altered metabolism and potential long-term health risks....
Exercise Rewires Immunity, Influencing Disease and Aging
Exercise doesn’t just strengthen muscles—it rewires immunity. Acute workouts and long-term training reshape immune cell behavior through exerkines, metabolites, blood flow, and even the gut microbiome, with implications for cancer, autoimmunity, and healthy aging. #ExerciseImmunology #Healthspan #Immunology https://t.co/ieYqsZEw96
Deep Sleep Circuit Silences Stress, Reduces Anxiety
Deep sleep may be one of the brain’s most powerful anti-anxiety tools. Researchers identified a sleep-active circuit linking the parafacial zone, parabrachial nucleus, and BNST that suppresses stress-related signaling during slow-wave sleep and prevents anxiety-like behavior. #SleepScience #Neuroscience #MentalHealth https://t.co/0kEEWqKOGG
Exercise‑released Myokines Boost Brain, Inactivity Harms Cognition
Muscle talks to the brain. 💪🧠 Exercise triggers myokines & myometabolites that boost cognition, while inactivity sends harmful signals that impair brain function. This muscle–brain crosstalk shapes behavior and resilience to aging and neurodegeneration. @WuTsaiAlliance https://t.co/63skqJToIa
Centenarians Retain Youthful Immune Profile, Hinting at Longevity
Centenarians show immune function found in younger individuals. Their immune system show reduced inflammatory signaling, enhanced autophagy, and controlled cellular senescence. They have low or no autoimmune disease, robust immunity against cancer and a distinct immune cell profile. Together, these...
Sleep‑disrupted Voles Form Stronger Same‑type Bonds
Do “like-with-like” social bonds extend beyond humans? In prairie voles, pairs with early life sleep disruptions showed stronger social affinity than mixed pairs. A new model for studying compatibility and social connection. #Neuroscience #Behavior https://t.co/uVJ65aBejM https://t.co/SZyp423HWq
Sample Handling Critically Impacts NAD+ Aging Biomarker Accuracy
How you handle blood 🩸samples may dramatically distort NAD+ measurements. Freezing, freeze–thaw cycles, and dried blood spots caused major NAD+ loss. Methanol-based preservation largely stabilized levels—highlighting how pre-analytical methods can shape aging biomarker data. #Metabolism #Aging #NAD https://t.co/BVXXJgT344
Low Cerebral Blood Flow Predicts Accelerated Brain Degeneration
Lower cerebral blood flow (CBF) may quietly shape brain health and brain aging. In a well-studied cohort, reduced CBF at baseline was linked to worse brain microcircuitry and also steeper worsening of white & gray matter integrity over time—highlighting CBF...
16‑Hour Fast Enhances Cancer Immunotherapy via Metabolic Shift
A 16-hour fasting regimen may boost cancer immunotherapy. Transient nutrient stress reshapes tumor metabolism, increasing isoleucine in the TME and enhancing CD8+ T cell function. In mice & patients, short-term fasting improved immune response—offering a feasible way to strengthen treatment. #Fasting,...
Evening Workouts Enhance Diabetes Control, Reduce Inflammation
Timing matters 🕒 For type 2 diabetes, afternoon/evening exercise boosts insulin sensitivity & glycemic control, while morning workouts may raise blood sugar. Later workouts are also linked to lower cortisol, less inflammation & better oxidative capacity. #Diabetes #ExerciseScience @WuTsaiAlliance https://t.co/5Bc0PUAE9O
Vascular Dysfunction May Drive Cognitive Decline and Dementia
Emerging research links vascular dysfunction to cognitive decline in aging & dementia. Reduced blood flow and blood-brain barrier breakdown may play a key role—and could even be causally connected. Understanding this opens the door to new, much-needed therapies. #Neuroscience #Aging...
Brain Blood Flow Peaks Differ by Region Daily
Blood flow to various parts of the brain follows a daily rhythm 🧠 Regions like limbic & sensorimotor areas peak around midday, while the hippocampus has more blood flow at midnight—and shows the strongest connectivity with the brain’s master clock...
Sleep Essential for Brain Health in Neurodevelopmental Disorders
Sleep is vital for brain development—especially in children with neurodevelopmental disorders. Disruptions can affect brain function, hormones, metabolism & inflammation, potentially worsening conditions like autism & ADHD. More research = better care. #SleepScience #Neurodevelopment https://t.co/NhPu38RrEi
Immersive Dreams Make Deep Sleep Feel Deeper
Deep sleep may feel “deeper” not just because the brain slows down—but because dreams become more immersive 🌙 As sleep pressure drops overnight, vivid dreaming may help sustain the sensation of deep sleep. A new twist on how we experience...
Skipping After‑Dinner Snacks May Drive Early TRF Benefits
From 2.6M time-stamped diet records, we identified 5 clusters of commonly consumed items: Breakfast | All-day | Lunch | Dinner | After-dinner After-dinner: popcorn, beer, wine, ice cream. So when people stop eating early, they also (inadvertently) cut out this cluster—potentially explaining some...
Diet Diversity Spans From 20 to 86 Foods, Women Lead
We’re told to “eat a diverse diet”—but how diverse is it in reality? Over 2 weeks: • Lowest 10% consume ~20 unique items • Highest (novelty seekers) reach ~86 Interesting twist: women tend to sample more unique foods than men. Where do you fall? @NatMetabolism https://t.co/08GlVexklU
What People Actually Eat Every Two Hours, Revealed
We analyzed 2.6M food & beverage logs from ~20,000 people to uncover (among other insights) what’s consumed every 2 hours across a 24h day. Some usual suspects… and a few surprises. Take a guess—then check the list 👇 https://t.co/ifqEyMnIEp @NatMetabolism https://t.co/AEQgConEUz
Morning Run and Light Beat Jet Lag
