3 years on, with 1,000s of academics using it, this is still my #1 note-taking rule:

Don’t just summarise papers.
Take notes on topics, separate from papers.

Source notes = papers.
Topic notes = concepts.

Link ideas → sources.

That’s how notes turn into a second brain 🧠
And writing stops being scary.

Can We Prevent Dementia? Science Says Yes

1. Cognitive reserve protects your brain by reducing blood vessel damage, lowering chronic inflammation, and keeping senses sharp.

2. Mental, physical, and social activity strengthen this reserve and build resilience.

3. Hearing loss and depression are major risks. Fixing them could prevent almost half of dementia cases.

4. Life-course habits matter. Small daily actions over decades add up.

Could AI tools for work, summarizing, and learning boost brain stimulation and lower dementia risk?

2026，完全可以用notebooklm 的fast reasearch或 deep research 来自动收集资料，取代多年来手工google，一条条慢慢收集的过程。

主题研究 80% 的资料，可以 deep research 搞定；剩下少部分 20% 的资料，自己精挑细选，包括自己的 logseq 笔记，自己的阅读库资料等。

我录了一个小视频，看起来更直观。

这是一篇关于智能手机成瘾如何系统性削弱学习效果的论文。作者通过对来自 16 个国家、近 15 万名大学生的 44 项研究进行荟萃分析发现：

1️⃣ 智能手机成瘾显著损害学习效果
2️⃣ 学习时使用手机越多，负面影响越强
3️⃣ 关键受损的是「认知与学习能力」，而不只是成绩
4️⃣ 教育用途 ≠ 教育收益
5️⃣智能手机不是简单地“分散注意力”，而是在长期中系统性削弱学生的学习能力。

当然，在当前 AI 时代的大背景下，上述关于“手机削弱学习能力”的结论，是否仍然成立，抑或正在被重塑为一种全新的“人机协同学习范式”，本身就值得被重新审视。

Exercise vs Alzheimer’s: How Moving Your Body Protects Your Brain

Science-Backed Insights (2025 Review)

1. Alzheimer’s is not inevitable
Up to 30% of Alzheimer’s risk is linked to modifiable factors, including physical inactivity. Exercise is one of the strongest protective tools.
2. Exercise slows brain ageing linked to Alzheimer’s
Regular physical activity preserves hippocampal volume, supports memory, and delays cognitive decline, all early markers affected in Alzheimer’s disease.

3. Muscles release anti-Alzheimer’s signals
Exercise triggers muscle-brain crosstalk via myokines like BDNF, CSF1, VEGF, and cathepsin B, which promote neurogenesis, synaptic health, and brain blood flow.
4. BDNF protects memory circuits
Exercise-induced BDNF increases hippocampal size and memory performance, counteracting the hippocampal shrinkage seen in Alzheimer’s.

5. Exercise reduces neuroinflammation
Chronic brain inflammation accelerates Alzheimer’s pathology. Exercise regulates microglia activity and lowers inflammatory signalling in the ageing brain.
6. Better myelin, better cognition
Alzheimer’s is associated with early white-matter damage. Exercise supports myelination, improving neural communication and cognitive resilience.

7. Stronger blood-brain barrier = less amyloid buildup
Exercise improves blood-brain barrier integrity, enhancing clearance of amyloid-beta, a hallmark of Alzheimer’s disease.
8. ApoE4 risk is not destiny
Exercise stabilizes ApoE function, supports cholesterol balance in brain cells, and may reduce Alzheimer ’s-related damage even in genetically at-risk individuals.

Exercise doesn’t just slow ageing, it targets key Alzheimer’s mechanisms.

Move your muscles. Protect your memory. Future-proof your brain.

Creatine made simple: how your body builds and uses its energy buffer

Creatine is a molecule your body makes naturally to keep energy flowing smoothly, especially in muscles and the brain. Here’s how the system works:

1️⃣ Where It Begins

Creatine starts in your kidneys, where the amino acids arginine and glycine combine to form guanidinoacetate (GAA).
🟢 Example: This first step is like assembling the base structure of a battery.

2️⃣ The Liver Finishes the Job

Guanidinoacetate travels to the liver, where it’s methylated by S-adenosyl-methionine (SAM), a reaction that converts it into creatine.
🟢 Example: The liver adds the “charge” that activates creatine for energy storage.

3️⃣ Creatine Travels to Muscles
Once made, creatine moves through the bloodstream to muscles, the heart, and brain, where it acts as an energy reserve.
🟢 Example: About 95% of your creatine is stored in muscle tissue, ready to recharge your cells when energy runs low.

4️⃣ The Energy Exchange System

Inside muscle cells, creatine and ATP (your cell’s energy currency) are in constant exchange:
When energy is plentiful, ATP donates a phosphate to form phosphocreatine (stored energy).

During activity, phosphocreatine donates that phosphate back to ADP, quickly regenerating ATP.
🟢 Example: This is your body’s “instant energy buffer” during sprinting or lifting.

5️⃣ Creatine Recycling and Excretion

After use, some creatine converts into creatinine, a natural byproduct filtered out by the kidneys.
🟢 Example: This is why creatinine levels are used in blood tests to check kidney function.

6️⃣ Why It Matters
Creatine supports:

Rapid ATP regeneration in muscle and brain.

Cellular hydration and stability.
Methylation balance, since it uses SAM in its synthesis.
🟢 Example: Supplementing creatine doesn’t just enhance performance, it supports cellular metabolism and brain health too.

Creatine acts as the body’s built-in energy recycling system. Made in the kidneys and liver, stored in muscle, and constantly recharging ATP, it’s one of the most efficient energy buffers biology ever designed.

Why do myokines matter? BDNF grows muscle, Myostatin breaks it down. Exercise flips the switch, inactivity keeps "the lights off"

Mitochondrial health is crucial for overall health. Several nutrient and non-nutrient compounds have evidence for supporting mitochondrial function and health. Of note, regarding their effects on mitochondrial health, it is typical that most research concerning this topic is conducted in rodent models or cell cultures. However, many (but not all) of these nutrients also have some level of clinical data suggesting that they support mitochondrial health in the appropriate doses, circumstances, and populations.

Doses, bioavailability, tissue distribution, population demographics, and circumstance (e.g., presence of disease), etc. would play primary roles in determining the type of effect, the magnitude of effect, and location of the effect (e.g., liver, brain, heart, skeletal muscle, etc.) that such nutrients would have on mitochondrial health
