Finding the genetic cause of a rare disease is hard. Finding it when you have to coordinate research across unrelated families scattered around the world? That's a logistical nightmare wrapped in a scientific puzzle. But that's exactly what it took to identify ARHGAP19, a newly discovered gene...
Loneliness has hit epidemic proportions in modern societies. We're more connected than ever through our devices while somehow feeling more isolated than ever in our actual lives. Enter AI chatbots, stage left, with what looks like a perfect solution. They're always available, never judgmental,...
Your brain runs on a delicate balance of "go" and "stop" signals. Too much excitation and things get chaotic (seizures, anyone?). Too much inhibition and nothing happens at all. A study in eLife just discovered that a protein famous for one job has been moonlighting at a completely different gig,...
LRRK2 mutations are among the most common genetic causes of Parkinson's disease. When this protein goes wrong, dopamine neurons in the brain start dying, and the characteristic motor symptoms follow. Scientists have spent years trying to understand exactly what LRRK2 does and why its mutant forms...
You're sitting in therapy, talking through some issue that's been bothering you. Maybe it's a relationship pattern you keep falling into, or anxiety that won't let go. And then something clicks. You suddenly see the situation differently. The insight feels meaningful, maybe even transformative. But...
For decades, neuroscientists have been running a pretty simple playbook. Flash a light. Play a beep. Record the brain's response. Interpret that response as sensory processing doing its thing. Vision or hearing or touch, respectively.
There's a guitar in your closet. Maybe a keyboard. Possibly some watercolors from that phase you went through three years ago. They're gathering dust now, and every time you see them you feel a tiny pang of guilt for abandoning yet another hobby. Well, here's some news that might motivate you to...
We've spent decades securing computers. Firewalls, encryption, two-factor authentication. We've built entire industries around the idea that systems have vulnerabilities and bad actors will exploit them. But there's another system that processes information, has known weaknesses, and is under...
The brain loves a good plot twist, and the climbing fibers of your cerebellum just delivered one. For decades, neuroscientists had these neural pathways pegged as error reporters. You reach for a coffee cup and misjudge the distance? Climbing fibers fire to say "Whoops, try again." They were...
You don't often see researchers publicly declare their own field dead. It's bad for grants, awkward at conferences, and generally not a great career move. So when Giacomo Indiveri, one of the pioneers of neuromorphic engineering, publishes a commentary titled "Neuromorphic is dead" in Neuron, you...
Ever wonder how your brain manages to hear the difference between your friend whispering a secret and a truck barreling down the street? It all comes down to some incredibly precise wiring between your ear and your brain, and a study in eLife just uncovered one of the molecular matchmakers making...
Your brain handles five completely different senses. Vision works with photons hitting your retina. Hearing decodes pressure waves in the air. Touch registers mechanical forces on your skin. Smell and taste involve molecular detection. For decades, researchers studied each of these modalities...
Your brain is supposed to match. Not perfectly, of course, but connected regions tend to have similar characteristics: thickness, folding patterns, general organization. It's like how different rooms in a well-designed house share an architectural style. You can tell they belong together.
Your visual system didn't spring into existence fully formed. It developed in stages, following a carefully choreographed sequence that evolution has been perfecting for hundreds of millions of years. First, your brain practiced with spontaneous activity, neurons firing in patterns that laid down...
Your retina has a weird distinction in anatomy: it's the only part of your central nervous system you can look at without cutting through bone. Every other part of the brain and spinal cord is locked away behind skull and vertebrae. But the retina just sits there behind your pupil, accessible to...
When neuroscientists stick electrodes on your scalp and record brainwaves, they're supposed to be measuring brain activity. That's kind of the whole point. But here's an awkward finding from a new study in eLife: some of what we thought were age-related changes in brain dynamics are actually coming...
Picture this: you've got a super-smart AI that can look at brain scans and accurately identify autism. Sounds great, right? There's just one tiny problem. When you ask it "how did you know?", it basically shrugs and says "I just do." That's what scientists call a black box model, and it's about as...
Imagine installing a dimmer switch in your house, but instead of controlling lights, it controls specific neurons in your brain. And instead of flipping it with your finger, you activate it by taking a pill. That's basically what DREADDs are, and they sound like something a science fiction writer...
So you've been told your average blood pressure is fine. Great news! Except, plot twist: it might not be the whole story. Turns out, how much your blood pressure bounces around could matter just as much as where it lands on average. A new study in eLife built a mouse model to figure out exactly...
When you search for something, like spotting your friend in a crowded bar, your brain creates a mental template of what you're looking for. But here's a question that has been bugging neuroscientists for years: what does that template actually look like inside your head? Is it like you're already...
