Bizarre Mini Brains Offer a Fascinating New Look at the Brain

Brain balls sound like something straight out of a Tim Burton movie: starting as stem cells harvested from patients, they eventually develop into masses of living neurons, jumbled together in misshapen blobs. Just like the developing brain, these neurons stretch and grow, reaching out skinny branches that grab onto others to form synapses—junctions where one […]

Researchers Repair Brain Damage in Mice With Stem Cell Transplants

The human brain is a biological wonder with considerable skills. Regeneration, unfortunately, isn’t one of them. Save for one tiny V-shaped region within the hippocampus, the human brain’s ability to rebuild itself is nearly nonexistent. When neurons die, there’s no backup reserve of cells to replace them. Brain trauma — a blow to the head, a stroke, or neurodegeneration — can be brutally final. You’re not getting lost neurons back. An obvious solution is to… read more

The Tiny Brain Chip That May Supercharge Your Mind

How will we interact with the intelligent machines of the future? If you’re asking Bryan Johnson, founder of startup Kernel, he’ll tell you those machines should be implanted inside our brains. His team is working with top neuroscientists to build a tiny brain chip—also known as a neuroprosthetic—to help people with disease-related brain damage. In the long term, though, Johnson sees the product applicable to anyone who wants a bit of a brain boost. Yes, some might flag… read more

Incredible ‘Living’ Alzheimer’s Implant Clears Mouse Brains of Toxic Junk

Alzheimer’s may be the cruelest of brain diseases. Decades before the first signs of dementia strike, toxic protein clumps called amyloid plaques have been slowly, insidiously building up in the brain. The plaques clog the brain’s waste disposal system and wreak havoc on the delicate molecular machinery that underlies our memories, our history, our personality. By the time deceptively benign senile moments turn into full-blown dementia, it’s too late to treat. Our helplessness against dementia is especially frustrating, because scientists know how to slow it down if caught early. The answer is passive immunization. Just like vaccines stimulate the body… read more

Wireless AI Device Tracks and Zaps the Brain, Takes Aim at Parkinson’s

Zapping the brain with implanted electrodes may sound like a ridiculously dangerous treatment, but for many patients with Parkinson’s disease, deep brain stimulation (DBS) is their only relief. The procedure… read more

How Aged Neurons In a Dish Can Accelerate Longevity Research

Aging insidiously leaves its mark on our brains. With age, our well-oiled neuronal machinery slowly breaks down: gene expression patterns turn wacky, the nuclear membrane disintegrates, and neatly organized molecules… read more

Gene Therapy May Be Our Newest — and Most Effective — Weapon Against Alzheimer’s Disease

In 2001, a team of neurologists at UC San Diego began testing a highly experimental treatment for Alzheimer’s disease. The process sounds far more sci-fi than science: Using tiny pieces… read more

How the Brain Makes Memories: Scientists Tap Memory’s Neural Code

Some of our most treasured memories begin with a simple association: the smiling face of that special someone, tied forever to the place where you first met. Sadly, these episodic… read more
