The Research Code

Why do different neurodegenerative diseases affect the same cellular transport system? Our neurons depend on an intricate internal transport network to stay healthy and function properly. Along their long axons, essential materials such as proteins, mitochondria, vesicles and other cellular components must travel between different parts of the neuron. But what happens when this transport system begins to fail? Interestingly, disruptions in axonal transport have been observed in several neurological conditions, including amyotrophic lateral sclerosis (ALS), Huntington’s disease, Alzheimer’s disease and hereditary spastic paraplegia. Although these diseases have different genetic and molecular origins, they may expose a shared vulnerability: the dependence of long-projecting neurons on efficient intracellular transport. In her latest contribution to The Research Code, Dr. Şeyma Akarsu @sseymaakarsu explores: 🔬 Why long axons are particularly vulnerable to transport dysfunction. 🧬 How mutations affecting proteins such as spastin can disrupt axonal transport. 🧠 What experimental studies in ALS and Huntington’s disease reveal about potential therapeutic approaches. 💡 Why restoring a transport-related cellular function does not necessarily mean slowing or reversing disease progression. The broader question is fascinating: Could protecting the cellular transport system help neurons withstand the effects of different neurodegenerative diseases?

🌧️ Why rain feels so good (the science behind it) Ever stepped outside after rain or stood near a waterfall and felt instantly calmer and happier? There’s real physics (and a bit of biology) behind that feeling. The Lenard Effect: When water droplets splash, collide, or break apart — whether it’s rain hitting the ground, waves crashing, or water tumbling down a waterfall — they create "negative ions" in the air. This is called the "Lenard effect" (discovered in 1892). The splashing separates electrical charges, releasing clusters of negatively charged oxygen molecules into the surrounding air. These negative ions are naturally abundant near: - Waterfalls - Beaches and breaking waves - Rivers and moving water - Even regular rainfall (especially when drops hit surfaces) Do negative ions actually affect mood? Research suggests they can. A 2013 meta-analysis found that exposure to high levels of negative ions was linked to reduced symptoms of depression — particularly in people with seasonal affective disorder. The effect was stronger with higher concentrations of ions. While the exact mechanism isn’t fully settled, one popular explanation (popularized in certain health communities) involves the lungs. Negative ions may support the breakdown of serotonin there, which some researchers link to feelings of calm and reduced stress. Even without perfect consensus on the “why,” people consistently report feeling refreshed in these high-negative-ion environments. Part of it is probably the ions, part is the fresh air, cooler temperatures, and the simple joy of being in nature. Why do kids (and many adults) love getting caught in the rain? It’s not just “because negative ions.” Rain is: - Sensory-rich (sound, touch, smell) - Novel and playful - Often cooling on a warm day The combination of the physical sensation + any mood-lifting effects from the ions can make it genuinely uplifting. Want to try it? Next time it rains: - Step outside for a few minutes - Feel the drops on your skin or hands - Or just open a window and breathe the post-rain air You don’t need to get completely soaked — even brief exposure to natural negative ions can feel surprisingly good. Nature has been giving us this free “mood boost” for millions of years. Sometimes the simplest things really are backed by science. 🌿 (Pro tip: Waterfalls are basically negative-ion factories — if you ever get the chance to stand near one, do it.)

You’re not separate from everything. You’re just a small, temporary piece of this vast cosmos. Your life is short and you can only be in one place at a time, but you’re still connected to the whole. A beautiful reminder to zoom out.
