Researchers found these cells accumulate with age and high cholesterol—and can make up most of the liver’s immune cells in older mice. When scientists removed them, liver damage was dramatically reversed, even without diet changes. Thu, 16 Apr 2026 07:59:44 EDT https://www.sciencedaily.com/releases/2026/04/260416071947.htm https://www.sciencedaily.com/releases/2026/04/260414075637.htm Bread and other carbohydrate staples may be doing more than just filling plates—they could be quietly reshaping metabolism. In a surprising twist, researchers found that mice strongly preferred carbs like bread, rice, and wheat, abandoning their regular diet entirely. Even without eating more calories, they gained weight and body fat, not because they overate, but because their bodies burned less energy. Tue, 14 Apr 2026 09:21:12 EDT https://www.sciencedaily.com/releases/2026/04/260414075637.htm https://www.sciencedaily.com/releases/2026/04/260413043129.htm New research reveals that obesity affects men and women in surprisingly different ways. Men are more likely to develop harmful abdominal fat and signs of liver stress, while women show higher inflammation and cholesterol levels. These differences could help explain why health risks vary between sexes. Scientists say this could lead to more tailored treatments for obesity. Mon, 13 Apr 2026 09:29:20 EDT https://www.sciencedaily.com/releases/2026/04/260413043129.htm https://www.sciencedaily.com/releases/2026/04/260411090018.htm A major study suggests that when you eat could play a key role in staying lean. People who fast longer overnight and start their day with an early breakfast were more likely to have a lower BMI years later. Scientists think this is because eating earlier aligns better with the body’s internal clock. But skipping breakfast as part of intermittent fasting didn’t offer the same advantage—and may even be tied to unhealthy habits. Sat, 11 Apr 2026 09:24:37 EDT https://www.sciencedaily.com/releases/2026/04/260411090018.htm https://www.sciencedaily.com/releases/2026/04/260411022023.htm Putting on weight earlier in life may be more dangerous than previously thought. Researchers found that early adulthood obesity significantly raises the risk of premature death, especially from major diseases like heart disease and diabetes. The longer the body carries excess weight, the greater the damage appears to be. Interestingly, cancer risk in women didn’t follow this pattern, suggesting other biological factors are at play. Sat, 11 Apr 2026 09:54:18 EDT https://www.sciencedaily.com/releases/2026/04/260411022023.htm https://www.sciencedaily.com/releases/2026/04/260408225950.htm Chronic inflammation often works quietly in the background but can fuel serious diseases like diabetes, heart disease, and cancer. New research reveals that everyday plant compounds—like menthol from mint, cineole from eucalyptus, and capsaicin from chili peppers—can team up inside immune cells to dramatically boost their anti-inflammatory power. While individual compounds showed modest effects, certain combinations amplified results hundreds of times over by activating different cellular pathways at once. Thu, 09 Apr 2026 02:57:22 EDT https://www.sciencedaily.com/releases/2026/04/260408225950.htm https://www.sciencedaily.com/releases/2026/04/260408225948.htm Weight loss drugs and bariatric surgery may work differently, but they lead to surprisingly similar results inside the body. Both significantly reduce fat while also causing a modest loss of muscle, reshaping overall body composition. Since muscle helps protect against early death, this balance matters more than the number on the scale. The study suggests these treatments improve health—but not without trade-offs. Thu, 09 Apr 2026 03:09:30 EDT https://www.sciencedaily.com/releases/2026/04/260408225948.htm https://www.sciencedaily.com/releases/2026/04/260406192907.htm A surprising new study reveals that what you eat could play a powerful role in fighting cholera, a deadly diarrheal disease. Researchers found that diets rich in certain proteins—especially casein from dairy and wheat gluten—can dramatically reduce the ability of cholera bacteria to take hold in the gut, in some cases cutting infection levels by up to 100 times. These proteins appear to disable a key “weapon” the bacteria use to attack other microbes and dominate the gut environment. Tue, 07 Apr 2026 03:22:01 EDT https://www.sciencedaily.com/releases/2026/04/260406192907.htm https://www.sciencedaily.com/releases/2026/04/260402042803.htm Scientists have discovered a way to make French fries less greasy without ruining their taste. By combining regular frying with microwave heating, they reduce the amount of oil absorbed during cooking. The key lies in pressure inside the food—microwaves help push oil out instead of letting it seep in. The result: faster cooking, lower fat, and fries that can still stay crispy. Thu, 02 Apr 2026 19:15:35 EDT https://www.sciencedaily.com/releases/2026/04/260402042803.htm https://www.sciencedaily.com/releases/2026/04/260402042751.htm A new clinical trial suggests that what people eat could finally offer real relief for Crohn’s disease, a condition that has long lacked clear dietary guidance. Researchers found that a “fasting-mimicking diet” — involving just five days a month of very low-calorie, plant-based meals — led to noticeable improvements in symptoms for most participants. Even more striking, the diet didn’t just make patients feel better; it also reduced key biological markers of inflammation linked to the disease. Fri, 03 Apr 2026 04:55:54 EDT https://www.sciencedaily.com/releases/2026/04/260402042751.htm https://www.sciencedaily.com/releases/2026/04/260402000229.htm A new study suggests that one of the most widely used health metrics, BMI, may be getting it wrong for a large portion of the population. By comparing BMI classifications with precise body fat measurements using advanced DXA scans, researchers found that more than one-third of adults were placed in incorrect weight categories. Many people labeled as overweight or obese did not actually have the corresponding body fat levels, while others were missed entirely. Fri, 03 Apr 2026 00:19:13 EDT https://www.sciencedaily.com/releases/2026/04/260402000229.htm https://www.sciencedaily.com/releases/2026/04/260401071940.htm Hara hachi bu, a traditional Japanese practice of eating until you’re about 80% full, is gaining attention as a simple yet powerful way to improve health and reshape our relationship with food. Rather than promoting strict dieting, it encourages slowing down, tuning into hunger cues, and eating with awareness and gratitude. Research suggests it may help reduce calorie intake, support healthier food choices, and prevent long-term weight gain. Thu, 02 Apr 2026 07:03:26 EDT https://www.sciencedaily.com/releases/2026/04/260401071940.htm https://www.sciencedaily.com/releases/2026/04/260401071936.htm Millions of people start work before sunrise—but their brains aren’t ready for it. A new clinical trial has found that the wake-promoting drug solriamfetol can significantly boost alertness in early-morning shift workers struggling with shift work disorder. Participants who took the drug were able to stay awake and function better throughout full shifts, with improvements in productivity, safety, and daily performance. Wed, 01 Apr 2026 08:10:42 EDT https://www.sciencedaily.com/releases/2026/04/260401071936.htm https://www.sciencedaily.com/releases/2026/03/260330233357.htm A new study suggests that simplifying your diet by eating the same meals and keeping your calorie intake consistent could help you lose more weight. Researchers found that people who followed predictable eating routines during a 12-week program lost more weight than those who constantly changed what they ate. By reducing daily food decisions, routines may make it easier to stick with healthy habits in a world full of tempting options. Mon, 30 Mar 2026 23:45:16 EDT https://www.sciencedaily.com/releases/2026/03/260330233357.htm https://www.sciencedaily.com/releases/2026/03/260330210905.htm Deep sleep does far more than rest the body — it activates a powerful brain-driven system that controls growth hormone, fueling muscle and bone strength, metabolism, and even mental performance. Scientists have now mapped the neural circuits behind this process, uncovering a delicate feedback loop in which sleep boosts growth hormone, and that same hormone helps regulate wakefulness. Mon, 30 Mar 2026 21:39:42 EDT https://www.sciencedaily.com/releases/2026/03/260330210905.htm https://www.sciencedaily.com/releases/2026/03/260330084511.htm A major analysis of nearly 10,000 patients shows that simple, non-drug treatments like knee braces, hydrotherapy, and exercise can significantly ease knee osteoarthritis symptoms. These approaches not only reduce pain and improve mobility, but also avoid the risks tied to common medications. The findings suggest that low-cost, accessible therapies could play a bigger role in how doctors treat arthritis in the future. Mon, 30 Mar 2026 08:52:03 EDT https://www.sciencedaily.com/releases/2026/03/260330084511.htm https://www.sciencedaily.com/releases/2026/03/260328043602.htm What teens eat might matter more for their mental health than previously thought. A sweeping review of nearly 20 studies found that healthier diets are often linked to fewer depressive symptoms, while poor eating habits may go hand in hand with greater psychological distress. Interestingly, focusing on whole dietary patterns—not just individual nutrients—showed more consistent benefits, suggesting that overall eating habits could play a meaningful role during this critical stage of brain development. Sun, 29 Mar 2026 04:02:35 EDT https://www.sciencedaily.com/releases/2026/03/260328043602.htm https://www.sciencedaily.com/releases/2026/03/260328024515.htm Scientists have identified a key biological system that helps brown fat burn energy by building the networks it needs to function. A protein called SLIT3 splits into two parts, with each piece guiding the growth of blood vessels and nerves inside brown fat. These structures allow the tissue to pull in nutrients and rapidly convert them into heat instead of storing them as fat. Sat, 28 Mar 2026 03:19:56 EDT https://www.sciencedaily.com/releases/2026/03/260328024515.htm https://www.sciencedaily.com/releases/2026/03/260326075559.htm Having both excess belly fat and low muscle mass isn’t just unhealthy—it’s potentially deadly, raising the risk of death by 83%. This condition, called sarcopenic obesity, creates a vicious cycle where fat accelerates muscle breakdown and inflammation. Researchers found it can be identified using simple measurements, not costly medical tests. That means earlier detection—and a real chance to intervene before serious decline sets in. Fri, 27 Mar 2026 01:23:23 EDT https://www.sciencedaily.com/releases/2026/03/260326075559.htm https://www.sciencedaily.com/releases/2026/03/260326011458.htm Vivid dreams might be doing more than just entertaining your mind at night. Researchers found that immersive dreaming can actually make sleep feel deeper and more refreshing, even when brain activity is high. Surprisingly, people reported their deepest sleep after intense dream experiences, not just during quiet, inactive periods. This suggests dreams may play a key role in helping us feel truly rested. Thu, 26 Mar 2026 02:00:56 EDT https://www.sciencedaily.com/releases/2026/03/260326011458.htm https://www.sciencedaily.com/releases/2026/03/260325005914.htm By closely monitoring fish throughout their lives, researchers found that simple behaviors in midlife—like movement and sleep—can predict lifespan. Fish that stayed active and slept mostly at night tended to live longer, while those slowing down earlier lived shorter lives. Surprisingly, aging didn’t unfold smoothly but in sudden jumps between stages. The work suggests that tracking daily habits in humans could reveal early clues about how we age. Thu, 26 Mar 2026 07:18:41 EDT https://www.sciencedaily.com/releases/2026/03/260325005914.htm https://www.sciencedaily.com/releases/2026/03/260324024259.htm Nearly half of Americans don’t know that processed meat increases colorectal cancer risk, according to a new poll. But once they learn the connection, most support warning labels—suggesting people want clearer information. Experts warn that awareness is lagging even among healthcare providers. The good news: diets rich in plant foods and fiber, along with healthy habits, can dramatically lower risk. Wed, 25 Mar 2026 00:38:30 EDT https://www.sciencedaily.com/releases/2026/03/260324024259.htm https://www.sciencedaily.com/releases/2026/03/260323005543.htm Postmenopausal women may have a powerful new edge in the battle against weight gain. A Mayo Clinic study found that those using menopausal hormone therapy while taking the obesity drug tirzepatide lost about 35% more weight than those on the drug alone. The findings hint at a surprising synergy between hormones and cutting-edge weight-loss medications, potentially opening the door to more effective, personalized treatments for millions of women facing increased cardiometabolic risks after menopause. Mon, 23 Mar 2026 21:06:37 EDT https://www.sciencedaily.com/releases/2026/03/260323005543.htm https://www.sciencedaily.com/releases/2026/03/260319074604.htm Eating large amounts of ultra-processed foods like chips, frozen meals, sugary drinks, and packaged snacks may significantly raise the risk of serious heart problems. In a major U.S. study, people consuming around nine servings per day had a 67% higher risk of heart attacks, strokes, or death from heart disease compared to those eating about one serving. The risk didn’t just jump at high levels either. Each additional daily serving increased the likelihood of these events by more than 5%, even after accounting for calories, overall diet quality, and common health conditions. Thu, 19 Mar 2026 20:54:23 EDT https://www.sciencedaily.com/releases/2026/03/260319074604.htm https://www.sciencedaily.com/releases/2026/03/260319074558.htm Carrying extra fat around the waist may be more dangerous than the number on the scale suggests. Researchers found that belly fat was more strongly linked to heart failure risk than BMI, even in people with normal weight. Inflammation seems to play a key role, helping explain why this type of fat is especially harmful. Measuring waist size could offer a simple way to detect hidden risk earlier. Thu, 19 Mar 2026 19:40:51 EDT https://www.sciencedaily.com/releases/2026/03/260319074558.htm https://www.sciencedaily.com/releases/2026/03/260319044648.htm Stopping popular weight-loss injections like Ozempic or Mounjaro might not trigger the dramatic rebound many fear. A large real-world study of nearly 8,000 patients found that most people who discontinue these drugs manage to keep the weight off—or even continue losing—by restarting treatment, switching medications, or adopting lifestyle changes. While earlier clinical trials suggested rapid weight regain, this new evidence paints a more hopeful picture. Thu, 19 Mar 2026 23:08:04 EDT https://www.sciencedaily.com/releases/2026/03/260319044648.htm https://www.sciencedaily.com/releases/2026/03/260318033143.htm Scientists have mapped the genetics of cancer in cats for the first time at scale, uncovering major overlaps with human cancers. Key mutations—like those linked to breast cancer—appear in both species, and some human cancer drugs may also work in cats. Because pets share our environments, these similarities could reveal shared causes of cancer. The research could lead to new treatments that benefit both animals and humans. Wed, 18 Mar 2026 19:12:17 EDT https://www.sciencedaily.com/releases/2026/03/260318033143.htm https://www.sciencedaily.com/releases/2026/03/260318033138.htm Your morning coffee or tea could be quietly supporting your brain health. A long-term study found that moderate consumption of caffeinated coffee or tea was linked to an 18% lower risk of dementia and better cognitive performance over time. The benefits appeared strongest at 2–3 cups of coffee or 1–2 cups of tea daily—and even held true for people genetically predisposed to dementia. Wed, 18 Mar 2026 06:47:36 EDT https://www.sciencedaily.com/releases/2026/03/260318033138.htm https://www.sciencedaily.com/releases/2026/03/260318033129.htm For years, people with prediabetes have been told the same thing: lose weight or risk developing diabetes. But new research flips that idea on its head, showing that blood sugar can return to normal even without shedding pounds. The key isn’t just how much fat you carry—it’s where it’s stored. Harmful fat deep in the abdomen fuels inflammation and disrupts insulin, while fat under the skin can actually support healthier metabolism. Thu, 19 Mar 2026 02:32:09 EDT https://www.sciencedaily.com/releases/2026/03/260318033129.htm https://www.sciencedaily.com/releases/2026/03/260318033107.htm A new study suggests that eating less sweet food doesn’t make people crave it any less—or improve their health markers. Participants who increased or decreased sweetness in their diets showed no changes in preferences, weight, or disease risk. Many even returned to their old eating habits over time. Researchers say it may be time to rethink guidelines that focus on cutting sweetness instead of reducing sugar and calories. Thu, 19 Mar 2026 06:57:52 EDT https://www.sciencedaily.com/releases/2026/03/260318033107.htm https://www.sciencedaily.com/releases/2026/03/260317064444.htm Early life stress may set the stage for long-term digestive problems by disrupting the gut-brain connection. Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different biological pathways control different gut issues, hinting at more personalized treatments in the future. The research also highlights how a child’s early environment can have lasting physical effects—not just emotional ones. Tue, 17 Mar 2026 22:08:54 EDT https://www.sciencedaily.com/releases/2026/03/260317064444.htm https://www.sciencedaily.com/releases/2026/03/260317015928.htm Researchers have identified a surprising brain pattern that may help explain why people with ADHD often struggle to stay focused. Even while awake, their brains can slip into brief episodes of “sleep-like” activity during demanding tasks. These moments are linked to more mistakes, slower reaction times, and lapses in attention. Tue, 17 Mar 2026 02:25:43 EDT https://www.sciencedaily.com/releases/2026/03/260317015928.htm https://www.sciencedaily.com/releases/2026/03/260315004407.htm Melatonin is now widely used to help children sleep, but scientists say the enthusiasm may be getting ahead of the evidence. A major review found clear benefits for children with conditions like autism and ADHD, yet far less data exists for typical childhood insomnia. Researchers also warn about mislabeled supplement doses and rising accidental ingestions among young kids. Experts say melatonin should be used carefully and only alongside proven behavioral sleep strategies. Sun, 15 Mar 2026 07:08:26 EDT https://www.sciencedaily.com/releases/2026/03/260315004407.htm https://www.sciencedaily.com/releases/2026/03/260314030521.htm When the Asian financial crisis sent rice prices soaring in Indonesia in the late 1990s, the shock didn’t just strain household budgets—it left lasting marks on children’s bodies. Researchers from the University of Bonn found that kids exposed to the food price surge were more likely to experience stunted growth and, years later, a higher risk of obesity. The findings suggest that during crises, families often maintain calorie intake but cut back on nutrient-rich foods, creating hidden nutritional deficiencies that disrupt healthy development. Sun, 15 Mar 2026 04:53:48 EDT https://www.sciencedaily.com/releases/2026/03/260314030521.htm https://www.sciencedaily.com/releases/2026/03/260313002645.htm In medieval Denmark, people could pay for more prestigious graves closer to the church — a sign of wealth and status. But when researchers examined hundreds of skeletons, they discovered something unexpected: even people with stigmatized diseases like leprosy were buried in these high-status spots. Instead of excluding the sick, many communities appear to have treated them much like everyone else.

Patients taking higher doses experienced up to 47% fewer pauses in breathing and improved oxygen levels during sleep. The drug helps stabilize breathing signals in the brain, reducing airway collapse. Scientists say the findings could pave the way for a pill-based alternative to CPAP machines. Wed, 11 Mar 2026 06:19:22 EDT https://www.sciencedaily.com/releases/2026/03/260311004816.htm https://www.sciencedaily.com/releases/2026/03/260311004725.htm Teenagers naturally fall asleep later, which makes early school start times a recipe for chronic sleep deprivation. Researchers studying a Swiss high school that introduced flexible start times found that students overwhelmingly chose to begin later—and ended up sleeping about 45 minutes longer each school night. The extra rest led to fewer sleep problems, better well-being, and improved academic performance. Wed, 11 Mar 2026 18:49:23 EDT https://www.sciencedaily.com/releases/2026/03/260311004725.htm https://www.sciencedaily.com/releases/2026/03/260308201620.htm Exercise normally boosts the body’s ability to use oxygen, a key marker of health and longevity — but high blood sugar can block that benefit. Researchers found that a ketogenic diet helped mice normalize blood sugar and dramatically improved how their muscles responded to exercise. Their muscles became better at using oxygen and built more endurance fibers. The results suggest diet and exercise may work together in surprising ways to improve metabolic health. Mon, 09 Mar 2026 18:24:51 EDT https://www.sciencedaily.com/releases/2026/03/260308201620.htm https://www.sciencedaily.com/releases/2026/03/260308201618.htm Pre-workout supplements promising extra energy for workouts may come with a hidden cost: severely reduced sleep. A study of people aged 16–30 found users were more than twice as likely to sleep five hours or less per night. Many of these products pack huge doses of caffeine and stimulants that can linger for hours. Researchers say the findings raise concerns about the impact on young people’s health and development. Mon, 09 Mar 2026 17:02:26 EDT https://www.sciencedaily.com/releases/2026/03/260308201618.htm https://www.sciencedaily.com/releases/2026/03/260307213252.htm A growing trend called “fibermaxxing” is putting dietary fiber in the spotlight—and for good reason. Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate blood sugar and cholesterol. Researchers say getting enough fiber may even lower the risk of conditions like obesity, diabetes, and certain cancers.

When parents practiced mindfulness and stress-management skills, their kids showed healthier eating patterns and avoided the weight gain seen in families that only focused on diet and exercise. Sun, 08 Mar 2026 20:28:48 EDT https://www.sciencedaily.com/releases/2026/03/260307213228.htm https://www.sciencedaily.com/releases/2026/03/260306224229.htm Scientists studying 1,300 golden retrievers have uncovered genetic clues explaining why some dogs are more anxious, energetic, or aggressive than others. Remarkably, several of the same genes linked to canine behavior are also tied to human traits like anxiety, depression, and intelligence. The discovery suggests dogs and humans share biological roots for emotions and behavior. Understanding these links could help owners better interpret their pets’ reactions and even improve training and veterinary care.

Despite affecting nearly 600 million people worldwide — and potentially a billion by 2050 — the most powerful treatment isn’t surgery or medication. It’s exercise. Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological processes driving joint damage.

Researchers found that people who eat more fruits and vegetables known to carry higher pesticide residues—such as strawberries, spinach, and bell peppers—also have significantly higher levels of those chemicals in their urine. While produce remains a cornerstone of a healthy diet, the findings highlight how everyday food choices can drive real-world exposure to substances linked to cancer, hormone disruption, and developmental harm.

Tapioca pearls made from cassava can absorb heavy metals like lead, and in large amounts they may slow digestion or even cause blockages. The drink is often loaded with sugar—sometimes more than soda—raising risks for cavities, obesity, diabetes, and fatty liver disease. There are even reports linking frequent consumption to kidney stones and poorer mental health.

In a study of nearly a million veterans, researchers found that having both insomnia and sleep apnea dramatically raises the risk of hypertension and heart disease. The two conditions don’t just coexist—they interact in ways that intensify strain on the heart. Addressing sleep problems early could help prevent cardiovascular disease before it starts.

By combining caffeine with CRISPR gene editing, researchers have created a system that allows cells to be programmed in advance — and then activated simply by consuming a small dose of caffeine from coffee, chocolate, or soda. The approach, known as chemogenetics, lets scientists precisely turn gene-editing activity on and off inside targeted cells, including powerful immune T cells that can fight cancer.

The boost in heat production was nearly as powerful as constant exposure to cold temperatures. The mice didn’t eat less or exercise more; they simply generated more heat in their beige fat. The discovery hints that diet alone might activate the body’s calorie-burning machinery.

New projections from the American Heart Association warn that over the next 25 years, cardiovascular disease will rise sharply, driven largely by a surge in high blood pressure, diabetes, and obesity. By 2050, nearly 60% of women in the U.S. could have high blood pressure, and close to one in three women ages 22 to 44 may already be living with some form of heart disease.

People with metabolic syndrome who followed a short, calorie-reduced oat-based plan saw their harmful LDL cholesterol drop by 10%, along with modest weight loss and lower blood pressure. Even more surprising, the cholesterol benefits were still visible six weeks later.

In very old age, staying strong and maintaining muscle matters more than long-term disease prevention. Older adults who included fish, eggs, or dairy were just as likely to become centenarians as meat eaters, suggesting that key nutrients may make the difference. The takeaway: nutrition needs change dramatically with age.

After reviewing dozens of clinical trials involving more than 13,000 participants, researchers found that benefits for knee osteoarthritis pain were minimal and tended to shrink in larger or longer-term studies.

Researchers found that intense workouts change the balance of bacteria and important compounds in athletes’ digestive systems. When training loads dropped, diet quality slipped and digestion slowed, triggering different microbial shifts. These hidden changes might influence performance in ways scientists are only beginning to understand.

Instead of targeting a specific virus or bacterium, the nasal spray vaccine supercharges the lungs’ own immune defenses, keeping them on high alert for months. In mice, it slashed viral levels, prevented severe illness, and even blocked allergic reactions.

Scientists found that active ingredients from isoxazoline treatments pass into pet feces, exposing dung-feeding insects to toxic chemicals. These insects are essential for nutrient cycling and soil health. The findings suggest everyday pet treatments could ripple through ecosystems in surprising ways.
