You used to think you were addicted to your phone. You'd said it yourself, casually, probably while scrolling Instagram at 1 a.m. on a work night - "I'm literally addicted to this thing." But then a neuroscientist came along and said, politely but firmly, that you probably aren't. Not clinically,...
Somewhere around 2013, Madeline Lancaster was staring at a clump of stem cells that had done something no one asked them to do. Instead of growing into a flat, well-behaved sheet of neurons - the kind that fills textbooks and grant applications - the cells had self-organized into a...
If you're a neuron in the hippocampus, you have two choices: keep quietly filing away memories like the diligent librarian you are, or moonlight as an unwitting accomplice in one of biology's most elaborate heists. Because it turns out, cancer doesn't just grow - it networks. And your nervous...
If you're a neuron in the hippocampus, you have two choices: fire off your little electrical blip against a flat metal pad that barely hears you - like whispering into a pillow - or snuggle up to a microscopic vertical tower that catches every syllable of your electrochemical gossip. For decades,...
The problem with studying how the brain filters information is that everything happens at once, everywhere, all the time. It's like trying to figure out which security guard at a concert is keeping out the rowdy drunks versus which one is redirecting people to the right entrance - while the music...
The loneliness epidemic has officially graduated from think-piece fodder to clinical concern. A December 2025 AARP survey found that four in ten Americans over 45 are lonely - a number that's been climbing steadily for over a decade. But while the usual headlines fixate on the emotional toll, a new...
If you Google "amnesia," you'll find page after page telling you that memories get erased - wiped clean like a hard drive that took a magnet to the face. Turns out, most of those search results are selling you an outdated story. A massive new review in Psychological Review is making a pretty...
Tucked deep inside each temporal lobe, roughly behind your ears and a couple of inches inward, sit two almond-shaped clusters of neurons called the amygdalae. If your brain were a city, these would be the fire stations - small, always staffed, and responsible for pulling the alarm the instant...
Right at this moment, as your eyes scan these words, your brain cells are distinguishing "self" from "not self" in a molecular dance that would make a bouncer at an exclusive club look amateur. Your neurons, astrocytes, and microglia are all quietly monitoring their own genetic material, making...
A single Purkinje cell - one of roughly 30 million crammed into a structure the size of your fist - unfurls a dendritic tree so elaborate it looks like a coral reef designed by a maniac with a protractor. Each of these cells receives input from up to 200,000 other neurons simultaneously. And...
