ALT 🧠 Your Brain Cleans Itself While You Sleep — Here’s Why You Shouldn’t Skip It Ever wondered if your brain does more than just dream while you sleep? Scientists have uncovered something almost like a secret cleaning crew inside your brain — a system that only works while you’re asleep. During the day, as you think, move, and live your life, your brain cells produce tiny bits of “waste” — leftover molecules from all that activity. If you don’t get enough sleep, that trash doesn’t get taken out. It piles up, slowing your thinking, making your memory foggy, and may even be linked to serious problems like cognitive decline later in life. Here’s the mysterious part: while you sleep, especially deep sleep, special fluid flows through your brain and carries that waste away. It’s called the glymphatic system — a network that works kind of like your body’s garbage disposal, but only when you’re resting.

ALT A Teenager’s $500 Invention Could Inspire Better Kidney Care At just 17, Canadian student Anya Pogharian began developing a low-cost dialysis machine after volunteering at Montreal General Hospital. She spent more than 300 hours building a prototype for around $500, which was later tested using human blood during an internship at Héma-Québec. Dialysis helps remove waste from the blood when the kidneys cannot function properly. Although her prototype was not an approved medical device, her idea highlighted the potential for making treatment more affordable and accessible. Sometimes, one young mind can inspire a big change in healthcare. Sources: CBC News; CTV News; Home Dialysis Central
