GLP-1 drugs like Ozempic have become the most effective anti-obesity medications ever developed, producing sustained weight loss far beyond what older appetite suppressants could manage. But the exact reason they work so well, and keep working over the long term,... Continue Reading →
Alzheimer's research moves at a punishing pace. Because the disease is age-related, scientists have to work with old mice, and each experiment can take a year and a half to two years before it even yields conclusions worth building on.... Continue Reading →
You see someone yawn across the room. Ten seconds later, you're yawning too. It happens with strangers on the subway, with dogs watching their owners, even sometimes just from reading the word "yawn" enough times. Researchers have been trying to... Continue Reading →

Researchers found that it isn't amyloid plaques themselves keeping the Alzheimer's brain awake — it's the brain's own immune cells overreacting to them, like a sprinkler system flooding the whole house over a small kitchen fire.
Every neuron in your brain is constantly drinking in its surroundings, pulling in nutrients, chemical signals, and bits of its own outer membrane in a process called endocytosis. It's how brain cells learn, remember, and stay maintained day to day.... Continue Reading →

Every night, in a state the brain enters without being asked, we become the authors of experiences we did not choose and cannot fully control. We fly. We sit exams for subjects we never studied. We speak with people who... Continue Reading →
