‘BPA-Free’ Chemicals Plus BPA Disrupt Lab-Grown Breast Tissue Three chemicals found in everyday plastics had no significant effect on lab-grown human breast tissue when tested one at a time at low doses. Combined at those same doses, they disrupted how the tissue developed and switched on genes tied to invasive lobular carcinoma, a breast cancer type whose…

A drug that new mothers sometimes take for a simple reason, to dry up breast milk they no longer need, may come with an unexpected second payoff: sharply lower odds of breast cancer in the years after childbirth. In a combined analysis of two large European studies, women who received cabergoline shortly after giving birth were about…

Gut Bacteria May Send Messages to Muscles, and Yogurt Could Join the Conversation A spoonful of yogurt, a sip of kefir, a bite of tempeh. These foods are usually marketed for gut health, but a new scientific review asks whether the bacteria inside them might also help keep muscles strong with age. Published in Communications Biology, the…

An afternoon nap is one of the small comforts of getting older, but these findings may make many think twice about their next nap. A new study that tracked nearly 1,000 older Americans for up to a decade found that people who napped most days or every day had a 48% higher risk of developing dementia than…

For decades, one number has largely decided who gets labeled as having obesity: body mass index (BMI), a formula built from height and weight. A new study of nearly 800,000 people found that the number tells a very different story depending on age. Among adults ages 65 to 74, 52% met a newer definition of obesity that…

Most people might picture ADHD as a fidgety kid who can’t sit still in class, not a 70-year-old at a memory clinic. A large new study suggests those two pictures may be more closely connected than most of us realize. Researchers combed through the health and genetic records of more than 187,000 Americans aged 50 and older.…

Marijuana is supposed to mellow people out, yet for some users a hit brings dread instead of calm. A new mouse study points to why: a single dose of a cannabis-like drug made fear-related brain cells fire harder, and switching those cells off stopped the drug from driving the animals to avoid a threatening smell. Freezing in…

Crack. One sharp pop from a pulled finger, and someone nearby is bound to issue the old warning: keep doing that and you’ll end up with arthritis. A sound that loud seems like it must be doing damage. Doctors who studied the habit in 1990 wrote that the arthritis link had long been considered “an old wives’…

Who comes to mind when you think of someone emotionally intelligent? Someone who can read a room, defuse an argument, and who knows exactly what to say when a friend is struggling? For many people, that person is a woman. It’s such a widely held belief that popular psychology treats it as fact. We decided to put…

The study identified two ways to reduce the environmental impact of medical devices: improving product design and making their use more efficient. Medical e-waste is emerging as a global challenge, with much of it not being recycled due to concerns over contamination, according to a study by the Waste Electrical and Electronic Equipment (WEEE) Forum. Electronic devices…

Air Quality Plans Focused on Tailpipes May Be Missing Summer Pollution Sources Tailpipes have long been the prime suspect for dirty city air. Over a summer month in one New York suburb, though, chemical products used in homes and businesses, from perfume and lotion to cleaning spray and paint, put more air-polluting gas into the sky than…

Yeast From Invading Fruit Flies Gives Off Scents That Beat a Known Pest Repellent A collapsed fruit fly colony in a New Jersey lab has led researchers to a smell that sends one of fruit farming’s most destructive pests packing. Two scent compounds tied to a yeast found during the collapse, isoamyl butanoate and 2-phenyl-1-propanal, caught zero…

Canadian Analysis Finds Permanent Standard Time Fits the Body Clock Better Than Permanent Daylight Saving Time In early January, the sun doesn’t rise until after 7:30 a.m. in cities from Vancouver to Halifax. Kids head to school under streetlights, and drivers scrape ice off windshields in the dark. A new analysis warns that permanent daylight saving time,…

Restoring One Muscle Fat Prevented Early Death in Adult Mice Take one fat molecule out of a mouse’s muscles, and the animal withers: smaller muscles, a weaker grip, an early death. Let the body make that molecule again, and the damage starts to heal. In a new study in Nature Aging, the wasting began to reverse in…

Parasite Can Flip a Biological Switch and Keep Going Without Oxygen A single-celled amoeba linked to contact lens eye infections and blindness keeps going even when its oxygen is cut off. According to a new study in the journal Cell, Acanthamoeba appears to pull it off by switching on a backup system that releases hydrogen gas. In…

Researchers Turned Eggshell Waste Into a Metal Reinforcement Using Only Friction Cracked eggshells usually end up in the trash, but researchers have locked them inside a rod of magnesium, a lightweight metal, without ever melting the metal. In tiny tests, the result held up better under squeezing than plain magnesium made the same way. Researchers at North…

Adults Assigned Diet Drinks Lost About as Much Weight as Water Drinkers Over Two Years Adults in a two-year weight-loss trial who drank diet sodas and other artificially sweetened beverages ended up with about the same results as adults who drank only water. Among participants who finished, those who drank water had lost an average of 8.2…

Small Trial Ties Daily Blueberries to Gut Changes in Older Adults With Low Mood A daily dose of blueberry powder, equal to about two cups of fresh berries, changed how common certain genes were among the gut bacteria of older adults with mild depressive symptoms. One change involved a bacterial pathway that could feed into making GABA,…

Magnetic Shielding Extended Life in a Fruit Fly Model of Parkinson’s Every person who has ever lived has spent every second of life inside a magnetic field. Earth’s magnetic field points compass needles north and helps migrating birds find their way. Whether the cells of the creatures living beneath it need that field for anything has been…

Going Remote Is Making Many Workers More Sedentary, Study Suggests On the days hybrid workers stay home instead of going into the office, they sit for about 44 extra minutes and get roughly 58 fewer minutes of light and moderate-to-vigorous activity combined, according to research published in the International Journal of Behavioral Nutrition and Physical Activity. The…

Six Minutes of Reading May Cut Stress by 68%, Research Review Says People reach for a book to calm down more often than they reach for a glass of wine or a hot bath, according to a new editorial pulling together decades of research on reading and mental health. One 2015 survey found that just six minutes…

That recurring middle-of-the-night wake-up may feel like a sign that something is off. Yet researchers say it can also be a surprisingly ordinary result of what happens in the body before dawn. It has sparked a larger debate over whether our ancestors once treated nighttime wakefulness as normal. Is There Actually Something Special About Waking Up At…

Einstein’s Gravity Rule Faces Its Toughest Test Yet, Thanks to a Super-Chilled Atom Beam A hammer and a feather fall at the same rate in a vacuum, because gravity treats all matter equally. That rule sits at the core of Einstein’s theory of gravity, and scientists have checked it against atoms, neutrons and even antimatter. One strange…

Six Minutes of Reading May Cut Stress by 68%, Research Review Says People reach for a book to calm down more often than they reach for a glass of wine or a hot bath, according to a new editorial pulling together decades of research on reading and mental health. One 2015 survey found that just six minutes…

Dirty Air Linked To Higher Glaucoma and Cataract Risk, Large Study Finds For decades, warnings about dirty air have centered on the heart and lungs, organs long known to absorb the damage from soot, exhaust and industrial smoke. A large new analysis suggests the eyes deserve a place on that list too. Researchers pooled data from 41…

People with autism who rely on Medicaid live to an average age of just 64.9 years, nearly six years shorter than other Medicaid enrollees and almost 14 years shorter than the average American. That’s the central finding of a new analysis of more than two million Medicaid beneficiaries with autism, and it shows just how much shorter…

Scroll through TikTok or Instagram for five minutes and there’s a good chance a creator will explain exactly what to eat to look the way they do. A flat stomach. Toned arms. That “glowy” skin. The pitch always sounds simple: copy the creator’s diet, get the creator’s body. New research suggests that pitch is not only oversimplified…

This Blood Molecule Predicts How Fast ALS Will Progress ALS or Lou Gehrig’s disease, is characterized by awful, progressively worsening symptoms and no cure. However, a team of researchers in Japan says it may have found a potential path toward new treatment options, and it started with something as ordinary as a blood sample. Their new paper…

Losing weight can help a struggling liver, but a new study suggests the number on the scale isn’t the whole story. Two people can lose the exact same amount of weight and walk away with very different livers, depending on what they ate to get there. That’s the takeaway from a new clinical trial that pitted three…

Breakfast is widely considered one of the most important parts of a child’s day. A new national poll finds that nearly all school-age kids are eating something in the morning before class. For many families, though, getting a nutritious meal on the table is a daily struggle, shaped by picky eaters, rushed mornings, and kids who are…

Blood Vessels, Ovaries, and Prostates Don’t Age on the Same Clock Blood vessels might already be showing wear and tear by the time an individual turns 35, decades before some other organs start to change. A new study suggests that’s not random. Different tissues appear to follow distinct structural-aging patterns across adulthood, some breaking down early, some…

Owning a Light Lamp Didn’t Help Older Adults. Using It Early Did An aging parent who spends the day in a dim living room, curtains half-drawn, lamps left off until evening, might be quietly working against their own health. A new study of 202 older adults across three European cities found that a cheap, store-bought light therapy…

Emotional Intelligence Won’t Save Your Memory. This Trait Might. A person who spent decades in a demanding career, kept up a challenging hobby, or stayed in school longer tends to remember things more accurately in old age, according to new research out of Italy. Emotional intelligence, despite its reputation as a marker of a sharp mind, showed…

For anyone with asthma who has ever felt too intimidated or too worn out to start a formal exercise program, a new study offers a welcome shortcut. Getting people to walk more and sit less, with coaching and a fitness tracker, worked about as well as structured treadmill workouts for controlling asthma symptoms. Researchers in Brazil put…

Blood Vessels, Ovaries, and Prostates Don’t Age on the Same Clock Blood vessels might already be showing wear and tear by the time an individual turns 35, decades before some other organs start to change.

What 300,000 People’s Diets Reveal About Preventing High Blood Pressure A bowl of lentil soup or a block of tofu may benefit cardiovascular health, according to a new analysis tying legumes and soy to a lower risk of high blood pressure. The research pulled data from more than 300,000 people across multiple countries, and the pattern held:…

Masculine, Still Image-Conscious: Appearance Concerns Pushed Men To Diet More Than Health Scares A man walks past a mirror, catches sight of himself without a shirt on, and mutters something unprintable under his breath. That moment, not a doctor’s warning or a health class lecture, is often what finally pushes men to try losing weight. A study…

A toddler finds a gummy on the coffee table. It looks like candy. It smells sweet. Before anyone notices, the child has swallowed it. That gummy might contain marijuana, and it might not be the only edible drug parents now have to worry about vanishing off counters and out of purses. A new study published in BMC…

Results Show The Average American Is Out Of Energy Before 3 P.M. Somewhere between the lunch dishes and the afternoon inbox, most Americans simply run out of gas. New survey data puts a timestamp on it: 2:48 p.m., the average moment when energy starts sliding on a typical day. For one in five adults (21%), the drop…

Coconut oil has long had a place in kitchens and beauty products, but researchers are now making a serious case for putting it in jet engines. New research found that aviation biofuel made from coconut oil can power a small jet engine about as efficiently as traditional jet fuel, with lower unburned hydrocarbon emissions, though the blends…

When a 35-year-old man went in for a cardiology appointment in 2005, thyroid trouble was the last thing on his mind. His cardiologist felt something unusual in his neck and ordered an ultrasound. That single scan set off a chain of discoveries that would later give doctors the chance to act on his children’s inherited cancer risk…

Younger Adults With Eczema Face Surprisingly High Shingles Risk For millions of adults living with eczema, the daily struggle involves cracked skin, relentless itching, and a medicine cabinet full of creams and prescriptions. Now, a large study points to another health risk worth watching: shingles. Adults with eczema were 28% more likely to develop the condition, and…

Staying clear of diabetes, high blood pressure, and smoking through middle age may promote more than a decade of extra dementia-free years compared to peers carrying all three conditions. A large, long-running community-based study published in Neurology® Open Access and tracking 12,409 participants from four U.S. communities found that the gap in dementia-free years between the healthiest…

For women trying to conceive later in life, the uterus itself can be just as much of an obstacle as egg quality. Even with the best fertility treatments available, including donor eggs from younger women, older mothers still face higher rates of failed implantation and pregnancy loss. Scientists have long suspected the aging uterus plays a major…

Some people can stand outside on a summer evening and walk back in without a single bite. Others get absolutely devoured. It turns out this isn’t bad luck or imagination. Mosquitoes appear to be responding to different chemical and microbial cues on each person’s skin. A new study tested 119 people against three different disease-carrying mosquito species,…

Standing on one leg for up to 30 seconds sounds like a party trick. In a study of more than 13,000 older adults, better performance on that simple balance test was associated with a lower risk of dying over the following seven years. Researchers followed 13,423 community-dwelling adults aged 65 and older in Taiwan for a median…

Media Skepticism, Not Just COVID News, Predicted Vaccine Conspiracy Beliefs One popular explanation for vaccine conspiracy theories is that the pandemic created them; that a flood of confusing headlines and social media posts pushed people toward believing governments and drug companies were hiding the truth. However, distrust in mainstream media was already there when researchers started watching…

Most college students used to picture graduation as a finish line. A growing number now seem to see it as a starting gun in a job market they fear AI will reshape. In a new survey of 2,000 American students pursuing higher education, less than half said they feel good about the job market waiting for them…

Each Heatwave Could Make You Biologically 6 Months ‘Older’, Researchers Say Summer heat is more than a seasonal discomfort. A new study suggests it may be aging people from the inside out, faster than the calendar ever could. Researchers found that exposure to extreme heat events was linked to accelerated biological aging in middle-aged and older adults.…

The Belief That Leadership Isn’t Just for Certain People Helped Some Teens See Themselves as Leaders Most teenagers have heard some version of the phrase “born leader.” It shows up in yearbook superlatives, coaching pep talks, and praise handed to the student who always raises a hand first. But that phrase carries a second, quieter message: that…

Scientists from the University of Pennsylvania have developed a bioengineered chewing gum that can reduce harmful viruses and bacteria linked to head and neck cancer. Head and neck cancer is one of the most common cancers worldwide, which affects the mouth, throat, voice box, nose, and nearby tissues. A lot of these cases are linked to tobacco…

Two-Week Study Pinpoints the True Daily Trigger of Problematic Internet Use Millions of people scroll, game, or shop online to escape a rough day. It seems intuitive that stress and a bad mood would be the main culprits pushing someone toward problematic internet use. A large new study tracking 900 people over two weeks found something more…

Millions of Americans take antidepressants every day. Millions more reach for diet sodas, sugar-free gum, or low-calorie snacks sweetened with natural and artificial sweeteners. What happens when both of those things meet in the gut at the same time? According to a new study, the answer may be more tangled than previously thought. Researchers tested 39 commercially…

The Protein Network That Cleans Up Workout Damage, and Why It Doesn’t Last An unusually intense or unfamiliar leg workout can damage tiny structures deep inside muscle fibers. That much has been known for years. What scientists had not fully worked out was how muscle recognizes and clears that damage without disrupting the rest of the fiber.…

Financial stress is something millions of people know all too well. Most have dealt with the anxiety of an overdue bill or smaller than expected paycheck at some point. Now, a sweeping new study tracking people across seven decades suggests that kind of hardship may be linked to something far more lasting than day-to-day stress: measurable differences…

For many new mothers, breastfeeding is no longer only a matter of medical advice. On Instagram, it has hardened into something closer to a moral obligation, and a new study puts Spanish parenting influencers at the center of that conversation. Researchers at Universitat Pompeu Fabra in Barcelona analyzed 592 public comments on Instagram posts from five Spanish…

Parkinson’s disease slowly destroys the brain cells that produce dopamine, a chemical messenger essential for controlling movement. For decades, a drug called levodopa, usually paired with carbidopa, has been the go-to treatment for managing symptoms. Over time, though, some patients develop fluctuating responses, involuntary movements and other complications that make the drug harder to manage. Now a…

One Type of Mouth Bacteria Keeps Turning Up in People With Hand Arthritis For millions of people, the pain and stiffness of hand arthritis is just a fact of aging, something to manage, but rarely something doctors can explain at the root level. Now, a new study is pointing scientists toward an unexpected place: the mouth. People…

After Watching a TV Drama, the Brain Tracked Rivalries More Clearly Than Friendships Watching a TV show may largely feel like mental relaxation, but beneath the surface our minds are still at work. A brain imaging study suggests that when people learn who’s feuding with whom on screen, certain brain regions take special notice. Researchers compared how…

Why Your Waistline May Reveal More Cancer Risk Than the Scale Does For decades, doctors have warned that carrying extra weight raises cancer risk. A new study suggests the real danger may have been undercounted, and the reason comes down to how “overweight” has been measured all along. A team of researchers analyzed data from more than…

Millions of Americans take antidepressants every day. Millions more reach for diet sodas, sugar-free gum, or low-calorie snacks sweetened with natural and artificial sweeteners. What happens when both of those things meet in the gut at the same time? According to a new study, the answer may be more tangled than previously thought. Researchers tested 39 commercially…

Skipping breakfast before a gym session is hard enough. A new study points to an odd trick that might make the empty-stomach grind a little easier: a whiff of chocolate. Men who breathed in the scent of chocolate before and during a weight session cranked out more repetitions than they did after smelling plain water, and they…

People who speak more than one language seem to have younger brains, according to research presented Monday at the Federation of European Neuroscience Societies (FENS) Forum 2026 [1]. Our brains are made up of billions of nerve cells which need to communicate with one another. As we age, the connectivity in our brains tends to deteriorate and, as a result,…

Scientists Use Tragic Childhood Syndrome To Argue DNA Tags Help Cause Old Age Decline A child losing all their hair by age six. Bones so brittle they fracture without warning. An immune system failing before a kid even reaches their teens. These are not symptoms of old age. They are the reality for children born with a…

Cancer has a dirty trick: it can put itself to sleep. When tumor cells slip into a kind of biological hibernation, they become hard to kill, shrugging off treatment and lying low until conditions improve, then waking up and bringing the disease back. For decades, researchers have struggled to shut down this hiding strategy without causing serious…

Slathering on lotion after a morning shower feels like a task checked off for the whole day. A new study suggests that confidence may be misplaced. Researchers tested four popular moisturizers and found that, under the conditions tested, the measurable hydration boost they give skin generally fell back toward untreated skin within roughly three to five hours,…

How Much You Weighed at Birth May Determine How Hard Your Kidneys Work Under Pressure Most people have no idea what they weighed at birth. That number lives in a baby book or a parent’s memory, totally disconnected from adult life. But a new study says it may quietly shape how well the kidneys hold up under…

Scientists Discover How Pomegranate Triggers the Gut’s Own Repair System Crohn’s disease and ulcerative colitis both involve a gut lining that has lost its ability to keep bacteria contained, leaving the body’s immune system in a state of chronic overdrive. Scientists may have found a way to fix that. They’ve identified a specific chain of molecular events…

Dengue Has Already Found a Foothold in California, and Climate Change Could Make It Far Worse A mosquito-borne illness once considered a distant, tropical problem has been quietly taking root in California, and a new study finds that tens of millions of residents already live in areas where summer conditions are ripe for local outbreaks. Dengue fever…

Two Studies Find Gut Fungi Drive Childhood Allergy Risk, With Mouse Research Pointing to Infant Antibiotics as a Culprit Hundreds of millions of children worldwide live with allergic diseases, and the number keeps climbing.

That Mid-Afternoon Energy Crash May Have a Simple Fix: A 5-Minute Walk Every Hour Most American adults spend the better part of their waking hours planted in a chair, at a desk, on a couch, or behind a wheel. Researchers have known for years that this much sitting is bad for health, linked to higher rates of…

Do Cats Help With Stress? Study Finds Cat Interaction May Not Always Soothe Owners For decades, pet owners have sworn by the calming power of their animals. Rough day at work? Curl up with the cat. Feeling anxious? Let the dog climb into your lap. The idea that pets soothe stress has become something close to common…

Some national pride goes beyond flying a flag or cheering at the Olympics. It runs on a quieter, more brittle conviction that one’s country is exceptional, perhaps even the greatest, and that the rest of the world stubbornly refuses to admit it. Psychologists have a name for that mindset: national narcissism. While national narcissism appears to be…

Quitting the day job to work for yourself carries a certain mythology: the bold young founder, the garage startup, the freedom of answering to no one. A new study that followed thousands of Americans for more than three decades muddies that picture in a blunt way. For a large share of those who struck out on their…

Ancient DNA Hidden in Pacific Islanders Reveals Three Separate Encounters With a Mystery Ancestor People living in Near Oceania, a region spanning New Guinea, surrounding island chains, and the main Solomon Islands, carry more ancient, pre-modern human DNA than any other population on Earth. New research has found that their ancestors inherited genetic material from three distinct…

The United States government’s recent release of hundreds of previously classified Unidentified Anomalous Phenomena (UAPs) cases spanning the 1940s to the present, along with the new Steven Spielberg movie, Disclosure Day, about extraterrestrial life, has fuelled the idea that aliens are visiting Earth. In fact, polls in Australia, the U.S. and elsewhere indicate around a third of…

Your Parents’ DNA May Shape Your Traits in Ways You Didn’t Directly Inherit Genes don’t tell the whole story of why traits run in families. A new study of roughly 30,000 families found that a parent’s DNA may shape children’s height, body weight, and school performance not only through the genes passed down at conception, but through…

Aging Ankles Trade Efficiency for Stability, and New Research Shows Exactly When the Switch Happens Walking feels automatic to most people, something the body just handles. But inside every step is a finely tuned exchange between muscles, tendons, and the nervous system, and new research reveals that exchange starts to break down at the ankle as we…

Standing on a bus that lurches forward. Catching a stumble on an icy sidewalk. For younger people, these moments of lost balance are handled almost automatically. Fast, lower-level brainstem circuits fire off corrective signals before anyone even realizes what happened. But as people age, the brain has to recruit backup. A new study finds that older adults…

A diagonal earlobe crease called Frank’s sign may signal hidden heart disease risk, especially alongside diabetes, hypertension, smoking, or obesity. When people think about warning signs of heart disease, symptoms like chest pain, breathlessness, fatigue, or irregular heartbeat usually come to mind. But doctors say there may be another subtle clue hiding in plain sight – right…

Guava Juice May Boost Hemoglobin in Women For nearly half of all pregnant women worldwide, anemia is a daily reality. The condition, in which the body lacks enough healthy red blood cells to carry oxygen, is especially widespread in Indonesia, where nearly half of pregnant women and close to a third of teenage girls are affected, according…

Scientists Destroyed a Few Dozen Neurons in a Fish and Watched Its Social Life Fall Apart Researchers have captured the brain activity of a fish in the moments before it swims toward a companion, and the brain starts preparing that move several seconds before the fish does anything visible. Published in Nature Communications, the study shows this…

The rise of remote work since the pandemic has made businesses more reluctant to hire young, inexperienced workers and is the key driver of higher unemployment rates for recent college graduates, a study released Monday has found. The study, by the Federal Reserve Bank of New York, compared occupations that can be done remotely — such as…

Women Over 50 With Low Protein Intake Face Dramatically Higher Odds of Losing Basic Physical Independence Getting dressed, walking to the kitchen, or simply using the bathroom. These are everyday moments most people take for granted. But for millions of older adults across Europe, those tasks are becoming increasingly difficult. A large study tracking more than 38,000…

Board-Certified Physicians Put Popular LLMs Through Their Paces, and Found Real Problems When people feel a strange pain or notice a worrying symptom, more and more of them are skipping the doctor’s office and heading straight to an AI chatbot. It’s fast, free, and available at 3 a.m. But a study suggests that convenience might come with…

A new national survey found that nearly half of American adults (48%) feel their lives are seriously lacking in fun right now. Even more jarring, 12% say they can’t even remember the last time they had a full free day to enjoy themselves. It is not a trivial complaint. Researchers found that people who do manage to…

For most people, cheese is a guilty pleasure: something delicious but probably not great for you. That assumption may be worth revisiting. A recent study took a close look at three traditional British artisan cheeses and tracked how their bacterial communities and chemical profiles shifted from production to the moment they hit the dinner table. What researchers…

Ice Age Icebergs Left 3,000 Scratch Marks in the Great Lakes, and They Recorded Winds Blowing the Wrong Way Thousands of grooves carved into the bottoms of ancient lakes, left behind by drifting icebergs thousands of years ago, have quietly preserved a record of how winds moved across North America during the last Ice Age. Researchers say…

Along a meandering river in a warm and arid region that is now Thailand roughly 113 million years ago, a plant-eating behemoth almost 27m long browsed on the treetops without much fear of predators due to its sheer size. This was Nagatitan chaiyaphumensis, the largest-known dinosaur from Southeast Asia. Researchers have unearthed skeletal remains of Nagatitan, a…

Caring for a Loved One May Slow or Speed Mental Decline, Depending on the Burden For millions of Americans, taking care of an aging parent, a sick spouse, or an ailing friend is simply part of life. But a new study finds that not all caregiving is created equal, and that how much care someone provides, and…

People With Stronger Focus May Pay Less Attention to Social Media Posts, Study Finds People who are better at managing their mental focus may pay less attention to social media content once they’re connected to the person or page sharing it. Researchers argue this may reflect strategy, not laziness. Most people assume that those with stronger focus…

Recent research has highlighted that walking approximately 8,500 steps each day might effectively prevent weight regain in individuals who have lost weight. Traditionally, the guideline for daily step count has been set at 10,000; however, this new finding indicates a lower threshold may suffice. The study, conducted by specialists in the field of health and nutrition, found…

A large new analysis of randomized trials has found that regular exercise can meaningfully boost the odds of staying smoke-free, and that even a single short workout can blunt the urge to light up for up to 30 minutes afterward. Quitting smoking has never been easy. Standard treatments like nicotine patches, prescription medications, and counseling can roughly…

Study Links UPFs To Rising Dementia Risk Scores Potato chips, frozen dinners, and diet soda don’t exactly have a reputation for being brain food. But a new study of more than 2,000 Australian adults suggests these foods may be chipping away at something far more concerning than a waistline: the brain’s ability to pay attention. And eating…

A stick of chewing gum probably isn’t the first thing that comes to mind when thinking about cancer prevention. But a new study suggests it might be worth a second look. Researchers loaded a gum with proteins derived from an edible bean and tested it against the specific viruses and bacteria most strongly tied to head and…

  The top predator prowling the seas during the age of the dinosaurs 100 million years ago may have been the octopus. New analyses of fossilized jaws reveal that massive, kraken-like octopuses once hunted alongside other marine predators. They boasted eight arms and long bodies that extended more than 60 feet (18 meters), rivaling other carnivorous marine…

A stick of chewing gum probably isn’t the first thing that comes to mind when thinking about cancer prevention. But a new study suggests it might be worth a second look. Researchers loaded a gum with proteins derived from an edible bean and tested it against the specific viruses and bacteria most strongly tied to head and…

A crab scuttling sideways across a beach is one of the most recognizable movements in the animal kingdom. The shuffle is so iconic that “crabwalk” has become part of everyday language. But scientists have long debated a deceptively simple question: Did crabs figure out this trick once, or did different groups independently arrive at it? A new…
