New Research Debunks Myth That Brain Cells Stop Growing After Childhood

gizmodo.com Ed Cara 2026-02-12 05:00:50

You’ve probably heard the old canard that new brain cells simply stop forming as we become adults. But research out today is the latest to show that this isn’t really true. Scientists in Sweden led the study, published Thursday in Science. They found abundant signs of neural stem cells growing in the hippocampus of adult brains. The findings reveal more about the human brain as we get older, the researchers say, and also hint at potential new ways to treat neurological disorders. “We’ve found

While eating a certain food or adjusting your diet won't provide a miracle cure for headaches or migraines, it may offer some relief. That is, in addition to maintaining your hydration, exercise, sleep and stress management. "The most important thing I tell patients is that migraines are highly individualized," says Dr. Nicholas Church, a board-certified member of the American Board of Family Medicine and the American Academy of Family Physicians.

Tesla's Self-Driving Mode Causes It to Get Hit by Train

futurism.com Unknown 2026-02-14 09:25:04

Tesla's so-called "self-driving" features have some serious issues with train tracks — and in a recent instance, it led to a small collision with a moving freight train. As Pennsylvania-based broadcaster WFMZ reports, a family of three was forced to exit their Tesla in the wee hours of the morning after it decided, when in an assisted driving mode, to turn left onto some train tracks. Jared Renshaw, the fire commissioner for Southeastern PA's Western Berks County, told WFMZ that the car was in

A proof-of-concept neural brain implant providing speech

Stephen Hawking, a British physicist and arguably the most famous man suffering from amyotrophic lateral sclerosis (ALS), communicated with the world using a sensor installed in his glasses. That sensor used tiny movements of a single muscle in his cheek to select characters on a screen. Once he typed a full sentence at a rate of roughly one word per minute, the text was synthesized into speech by a DECtalk TC01 synthesizer, which gave him his iconic, robotic voice.

What Happens to Your Brain When You Use ChatGPT? Scientists Took a Look

Your brain works differently when you're using generative AI to complete a task than it does when you use your brain alone. Namely, you're less likely to remember what you did. That's the somewhat obvious-sounding conclusion of an MIT study that looked at how people think when they write an essay -- one of the earliest scientific studies of how using gen AI affects us. The study, a preprint that has not yet been peer-reviewed, is pretty small (54 participants) and preliminary, but it points tow

This Survey Asked Neuroscientists If Memories Can Be Extracted From the Dead. Here’s What They Said

gizmodo.com Natalia Mesa 2026-02-20 00:20:54

The allure and terror of transferring your consciousness to a computer has long been fodder for cyberpunk novels and billionaire-backed immortality startups. But a substantial chunk of neuroscientists think it might be possible to extract memories from a preserved brain and store those memories inside a computer, according to a new study. The study, published in the journal PLOS One, suggests that most neuroscientists believe that memory has a physical basis and, on average, give a 40% probabil

Could Ozempic Treat Migraines, Too? Small Study Finds Early Promise for GLP-1s

Got a blinding headache? Some GLP-1 therapy could surprisingly help. A recent clinical trial has found early evidence that these popular drugs, typically used to treat obesity and type 2 diabetes, may also reduce migraine episodes. Researchers in Italy conducted the small pilot trial, which involved dozens of patients living with obesity and chronic migraine headaches.

In the nineteenth century, the invention of anesthesia was considered a gift from God. But post-operative pain relief has continued to rely on opioids, derivatives of opium, the addictive substance employed since ancient times. Although no other drug has managed to match the rapid, potent, and broadly effective relief delivered by opioids, their side effects have led to decades of addiction and overdose, leaving researchers keen to find a better solution.
