Will AI Turn a Generation Into Copy-Paste Learners?
A recent MIT EEG study reported by Time found that students using ChatGPT showed significantly lower brain engagement during essay writing—exhibiting reduced neural, linguistic, and behavioral effort compared to peers who researched or used Google. Over time, they “got lazier with each subsequent essay,” frequently resorting to copy-and-paste, and underperformed overall.
The Sweetener in Diet Drinks That May Harm Your Blood Vessels.
A 2025 EMJ Neurology report highlights groundbreaking lab findings that the popular artificial sweetener erythritol—often found in sugar-free drinks—can impair brain blood vessel health. In simpler terms, this means erythritol could reduce blood flow to the brain and increase stroke risk.
It’s Never Too Late to Add Years to Your Life—Just Move More.
A 2025 study analyzing 85 previous studies found that people who stay consistently active have a 30–40% lower risk of early death—especially from heart disease. Even those who start exercising later in life still see a 20–25% drop in mortality risk, showing it’s never too late to change your future.
Women May Benefit Even More From Creatine Than Men.
A 2021 review in Nutrients by Smith‑Ryan et al. highlights that women have 70–80% lower natural creatine stores than men, making supplementation especially impactful for their health and performance.
Doctors Just Found 4 Hidden Roads to Alzheimer’s.
UCLA researchers uncovered four distinct “roadmaps” leading to Alzheimer’s by analyzing longitudinal health records from nearly 25,000 patients and validating findings in the All of Us cohort. These sequential diagnostic patterns predicted dementia better than any single risk factor.
Oversleeping After Concussion Could Slow Recovery.
A 2025 cohort study of 291 Canadian youths (ages 10–18) found that sleeping more than 9.9 hours per night in the first two weeks after a concussion was linked to more severe symptoms and a higher risk of lingering effects at four weeks.
Selenium May Protect Against Cancer, Diabetes, and Aging.
A 2025 review in Nutrients by Zhang dives into the crucial roles selenium plays in our bodies. As a key part of selenoproteins, this micronutrient helps balance redox reactions, regulate cell growth, support the immune system, and guard against DNA damage, chronic inflammation, insulin resistance, and neurodegeneration.
Tocotrienols May Boost Mood, Slow Aging, and Protect Your DNA.
A 2025 randomized controlled trial in Nutrients by Sharif et al. showed those who drank tocotrienols experienced better psychological well-being, lowered markers of oxidative stress, increased antioxidant enzymes, and improved genomic stability.
Creatine Sharpens Your Memory—Not Just Your Muscles.
Creatine’s known benefits for muscle energy appear to extend to the brain—boosting cognitive function via enhanced cellular energy supply. The memory improvements were consistent across sexes and independent of body composition changes, suggesting creatine supports brain performance directly.
96 Toxic Chemicals Found in Nearly Every Toddler.
A 2025 study by UC Davis analyzed 201 toddlers (ages 2–4) from four U.S. states and found 96 different chemicals in their urine—48 found in over half of the kids, 34 in more than 90%—many not even tracked by national surveys.
Regular Napping Could Protect Your Brain From Aging.
A 2023 study by Paz V et al. linked regular daytime napping to larger brain volume. Analyzing 378,932 people aged 40-69 from the UK Biobank, researchers used Mendelian randomization to find that those genetically prone to napping had brains 15.8 cm³ larger, equivalent to 2.6-6.5 years less brain aging.
AI Overload May Be Eroding Your Brain’s Power.
A new MIT Media Lab study (2025) found that using ChatGPT for essay tasks led to significantly weaker brain activity compared to writing without AI or using search engines, as shown by EEG scans. The ChatGPT group not only struggled to recall what they wrote, but also produced more formulaic text and felt less ownership over their work.
Running Literally Rewires Your Brain to Fight Alzheimer’s.
A 2024 study by Mass General Brigham found that exercise doesn’t just help memory—it actually activates specific genes that protect against Alzheimer’s. Mice with Alzheimer’s who used running wheels showed better memory, and scientists found that their brains had boosted activity in cells tied to blood vessels and immune defense.
Just One Minute of Exercise Has Major Health Benefits.
A 2023 summary from Georgia State University and the Society of Behavioral Medicine shows that micro-workouts—short bursts of physical activity lasting from 30 seconds to 10 minutes—can have major benefits for heart health, blood sugar control, mental well-being, and overall endurance.
Creatine Isn’t Just for Gym Rats—It’s Brain Fuel, Too.
In 2025, Dr. Richard Kreider of Texas A&M reviewed 685 clinical trials and found creatine to be not only safe, but vital for healthy aging. Beyond muscle gains, creatine powers brain cells, supports cognitive function, protects against stress, and helps older adults retain muscle and memory.
Sound Doesn’t Just Enter Your Ears—It Reshapes Your Brain in Real Time.
A 2025 study from Aarhus University and the University of Oxford introduced a new brain imaging method called FREQ-NESS, revealing that when you hear a steady rhythm or musical tone, your brain dynamically reorganizes its networks. Instead of passively receiving sound, the brain actively adjusts its internal wiring, orchestrating a complex interplay of brainwaves across multiple networks.
