What Your Nighttime Breathing Says About Your Health

For decades, sleep disturbance was a punch line: the cartoon dad snoring, the disgruntled partner burying their head under a pillow. But science is beginning to paint a less jovial picture. Sleep apnea—a relatively common disorder where breathing repeatedly stops and starts during sleep—is now being taken seriously as a potential biomarker for a host of major health conditions, from cardiovascular disease to Alzheimer’s, even anxiety and depression. “Sleep is just as important for health as die

How the brain increases blood flow on demand

The Pandemic Appears to Have Accelerated Brain Aging, Even in People Who Never Got Covid

More than five years after the start of the Covid-19 pandemic, we are still discovering the after-effects of not only the virus but also the prolonged period of stress, isolation, loss, and uncertainty that the pandemic caused. A new scientific study, published this month in Nature Communications, has revealed that the pandemic may have accelerated brain aging in people even if they were never infected with the coronavirus. Researchers at the University of Nottingham in the UK analyzed brain im

Somnee Smart Sleep Headband Review: High-Tech Help

I have struggled with insomnia for as long as I can remember. I’ve tried basically every sleep aid on the market, plus I need a sound machine, sleep mask, blackout curtain, and weighted blanket to even begin the process of trying to fall asleep. So I decided to try something new. Before bed, on and off for the past several months, I've been wearing Somnee, a wearable sleep tech headband that aims to map the brain using EEG (electroencephalogram) sensors to deliver individualized therapeutic sti

There's Neuralink—and There's the Mind-Reading Company That Might Surpass It

Mark Jackson is playing a computer game with his mind. As he reclines in bed, three blue circles appear on a laptop screen a few feet away. One turns red: the target. Jackson is in control of a white circle, which he needs to steer into the target without running into the blue obstacles. The game is a bit like Pac-Man. Except instead of a joystick, Jackson uses his thoughts to control his little white circle. To move left, he thinks about clenching his right fist once. To move right, he thinks a

How slow motion became cinema’s dominant special effect

About 20 years ago, a neuroscientist named David Eagleman strapped a bunch of students into harnesses, hoisted them to the top of an imposing metal tower, and then, without warning, dropped them 150 feet. Though the students landed safely in nets, the experience was—by design—terrifying. Eagleton wanted to simulate the feeling of plummeting to one’s death. His goal was to figure out why survivors of near-death experiences almost always said the same thing: “It felt like the world was going in sl

Brain Scans Reveal Why Waking Up Is Sometimes Such a Difficult Experience

Want to wake up feeling great? The secret might not be so simple as a multi-step nighttime routine, early bedtime, or a no-device rule. A new study suggests that how we fall asleep and how we wake up the next day may not be so similar as we once thought. Neuroscientists tracked 20 people’s brain activity as they woke up from sleep—sometimes naturally, sometimes by setting off an alarm—recording more than 1,000 awakenings in total. They found a pattern of neural activity signaled waking, but tha

Shi et al./Cell (CC-BY-4.0) A speedy imaging method can map the nerves running from a mouse’s brain and spinal cord to the rest of its body at micrometre-scale resolution, revealing details such as individual fibres travelling from a key nerve to distant organs1. Previous efforts have mapped the network of connections between nerve cells, known as the conn

New Study Flips Everything We Know About Addiction Upside Down

Since the 1970s, countless experts and the US government have sold the public a simple explanation for drug addiction, now clinically called substance abuse disorder: the myth of the gateway drug. The gateway drug — usually cast as weed, alcohol, tobacco, or inhalants — refers to the theory that the earlier a kid starts using drugs, the more likely they are to get into the harder stuff later in life, like heroin or cocaine. Though the idea was pioneered as early as the 1930s, the policy term wa

Scientists Succeed in Reversing Parkinson’s Symptoms in Mice

Cases of Parkinson’s disease have doubled in the last 25 years, according to figures from the World Health Organization. For decades, the scientists have investigated what triggers this disorder to mitigate its symptoms and anticipate its onset. Now, a series of experimental therapies are laying the groundwork for potentially reversing the condition, which affects nearly 10 million people worldwide and can generate costs of approximately $10,000 per patient per year, when considering direct and

Do You Really Learn When You Use AI? What MIT Researchers Found

Your brain works differently when you're using generative AI for a task than 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 toward the need for

Is It Cake? How Our Brain Deciphers Materials

One of the greatest questions of the modern age is: Is it cake? As in: Is it an espresso machine, or cake? Paint can, or cake? Air fryer, or …? Millions of viewers have watched rapt as TikTok bakers slice or bite into inedible-looking objects with fluffy, frosting-filled innards … or have tuned into Is It Cake?, the aptly named Netflix show. Why? As a form of entertainment, this kind of visual trick is hardly new. For centuries, artists have delighted in fooling us into thinking one material is

New Research Debunks Myth That Brain Cells Stop Growing After Childhood

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

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. But a lot has changed since

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

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

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

Startling Percentage of Neuroscientists Say We Could Extract Memories From Dead Brains

Image by Getty Images Studies When you die, your memories die with you, never to be experienced again. Or at least, that's always been how the case. Now, though, in an exercise to assess shifting scientific consensus, a cohort of 312 neuroscientists were quizzed by researchers on whether memories might live on in the structure of deceased brains. And a surprisingly larger number — 70.7 percent of the group — believe they may, findings which were newly published in the science journal PLOS One.

Scientists Intrigued to Discover That Human Brains Are Glowing Faintly

Image by Getty / Futurim Developments Scientists have some exciting news: your brain is likely glowing, whether you can see it or not. The news comes from researchers at Algoma University in Ontario, who found evidence that the human brain, of all things, possesses luminescent properties. Essentially, they found that as the brain metabolizes energy, it releases super-faint traces of visible light. Called ultra-weak photon emissions (UPEs), the flashes of light are emitted when electrons break

I deleted my second brain

Two nights ago, I deleted everything. Every note in Obsidian. Every half-baked atomic thought, every Zettelkasten slip, every carefully linked concept map. I deleted every Apple Note I’d synced since 2015. Every quote I’d ever highlighted. Every to-do list from every productivity system I’d ever borrowed, broken, or bastardized. Gone. Erased in seconds. What followed: Relief. And a comforting silence where the noise used to be. For years, I had been building what technologists and lifehacker

E.A. Spitzka's Studies of Exceptional and Deviant Brains (2024)

The younger Spitzka’s career flourished after he took a position at Thomas Jefferson University in Philadelphia, where he gained recognition for his studies on the relationship between brain structures and behavior. His particular interest lay in the extremes of human nature—both pathological and extraordinary—and he sought to understand the physiology behind deviance and brilliance. In addition to his academic pursuits, Spitzka served as the editor of the 1910 edition of Gray’s Anatomy, one of

The first non-opoid painkiller

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. This all changed in January 2025, when

MIT brain scans suggest that using GenAI tools reduces cognitive activity

Why it matters: As the use of generative AI becomes increasingly common in education, law, politics, media, and other fields, many worry that reliance on the technology may reduce cognitive independence. A recent study from MIT strongly supports this concern, indicating that the use of digital tools significantly alters brain activity. The newly published paper explains that as participants in an experiment wrote a series of essays, electronic brain monitoring revealed substantially weaker conn
