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.

Researchers found that sildenafil significantly improved symptoms in patients with Leigh syndrome—a rare and often fatal disorder that affects the brain and muscles. In a small study, patients showed stronger muscles, fewer seizures, and better recovery from dangerous metabolic crises, with some experiencing dramatic improvements in mobility and daily life. Tue, 31 Mar 2026 08:33:45 EDT https://www.sciencedaily.com/releases/2026/03/260331001107.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.

A large study of nearly 100,000 people found that it’s not just how much you move, but how intensely you move that matters. Short bursts of vigorous activity—like rushing for a bus or climbing stairs quickly—were linked to striking reductions in disease risk, especially for inflammatory conditions and brain health. Mon, 30 Mar 2026 01:07:46 EDT https://www.sciencedaily.com/releases/2026/03/260330001126.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/2026/03/260323005542.htm A new study suggests a widely used bone hormone could help relieve chronic back pain in an unexpected way. Instead of just strengthening bone, it appears to stop pain-sensing nerves from growing into damaged spinal areas. In animal models, this led to stronger spinal tissue and reduced pain sensitivity. The findings hint at a future treatment that tackles back pain at its biological roots.

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/2026/03/260318033134.htm A risky but often lifesaving surgery that removes damaged parts of the small intestine can leave patients facing a new threat: serious liver damage with no available treatment. Now, scientists have developed a promising compound that works directly in the gut to shield the liver and improve how the body absorbs nutrients. In mouse studies, the drug boosted weight gain, reduced harmful liver scarring, and avoided side effects by staying confined to the intestines. Wed, 18 Mar 2026 03:31:34 EDT https://www.sciencedaily.com/releases/2026/03/260318033134.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.

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.

Early studies in mice and patient-derived cells show the approach can restore normal brain cell function, raising hopes for future therapies. Fri, 06 Mar 2026 21:18:09 EST https://www.sciencedaily.com/releases/2026/03/260306145621.htm https://www.sciencedaily.com/releases/2026/03/260304184215.htm A new experimental drug is showing remarkable promise for children with Dravet syndrome, a severe genetic form of epilepsy. In clinical trials, the treatment zorevunersen cut seizures by as much as 91% while also improving quality of life for many patients. The therapy works by boosting the function of a key gene involved in nerve cell signaling. Encouraging results have led researchers to launch a larger Phase 3 trial. Wed, 04 Mar 2026 21:14:30 EST https://www.sciencedaily.com/releases/2026/03/260304184215.htm https://www.sciencedaily.com/releases/2026/03/260303145725.htm Stiff knees and aching hips may seem like an inevitable part of aging, but experts say we’re getting osteoarthritis all wrong. 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. Wed, 04 Mar 2026 16:35:02 EST https://www.sciencedaily.com/releases/2026/03/260303145725.htm https://www.sciencedaily.com/releases/2026/02/260225081208.htm A sweeping new analysis of the evidence suggests that exercise therapy — long promoted as a first-line treatment for osteoarthritis — may offer only small and short-lived relief, and in some cases might be no better than doing nothing at all. 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. Wed, 25 Feb 2026 23:43:58 EST https://www.sciencedaily.com/releases/2026/02/260225081208.htm https://www.sciencedaily.com/releases/2026/02/260222092317.htm Training harder may do more than build muscle—it could transform your gut. 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. Mon, 23 Feb 2026 23:45:43 EST https://www.sciencedaily.com/releases/2026/02/260222092317.htm https://www.sciencedaily.com/releases/2026/02/260222092306.htm A UCLA study in mice reveals that aging muscle stem cells accumulate a protein that slows repair but boosts survival. This protein, NDRG1, acts like a brake, preventing cells from activating quickly after injury. When researchers blocked it in older mice, muscle healing sped up dramatically — but stem cells became less resilient over time. The work suggests aging may reflect a survival trade-off rather than straightforward decline. Mon, 23 Feb 2026 23:02:05 EST https://www.sciencedaily.com/releases/2026/02/260222092306.htm https://www.sciencedaily.com/releases/2026/02/260221060946.htm Running extreme distances may strain more than just muscles and joints. New research suggests ultramarathons can alter red blood cells in ways that make them less flexible and more prone to breakdown, potentially interfering with how they deliver oxygen throughout the body. Scientists found signs of both mechanical stress from intense blood flow and molecular damage linked to inflammation and oxidative stress. Sat, 21 Feb 2026 07:59:29 EST https://www.sciencedaily.com/releases/2026/02/260221060946.htm https://www.sciencedaily.com/releases/2026/02/260216044003.htm Researchers have built a realistic human mini spinal cord in the lab and used it to simulate traumatic injury. The model reproduced key damage seen in real spinal cord injuries, including inflammation and scar formation. After treatment with fast moving “dancing molecules,” nerve fibers began growing again and scar tissue shrank. The results suggest the therapy could eventually help repair spinal cord damage. Mon, 16 Feb 2026 07:41:25 EST https://www.sciencedaily.com/releases/2026/02/260216044003.htm https://www.sciencedaily.com/releases/2026/02/260212234218.htm Scientists at Cedars-Sinai have uncovered a surprising repair system in the spinal cord that could open new doors for treating paralysis, stroke, and diseases like multiple sclerosis. They found that special support cells called astrocytes—located far from the actual injury—spring into action after damage. These “lesion-remote astrocytes” send out a protein signal, CCN1, that reprograms immune cells to efficiently clean up fatty nerve debris.

Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle to renew and support memory and learning. The findings raise hopes for treatments that could slow or even reverse aspects of brain aging.

Researchers showed that high levels of HIF1 actually cause harmful changes that make tendons brittle and prone to pain. In experiments, turning the protein off protected tendons — even under heavy strain.

But a sweeping 11-year analysis of Alaska’s long-running Permanent Fund Dividend program tells a different story. Researchers examined statewide hospital records and death data and found no increase in traumatic injuries or unnatural deaths after annual payments were distributed.

A large Dutch study tracking more than 65,000 adults over four years found that replacing 60 minutes of TV with other activities cut depression risk by 11% overall, and by nearly 19% in middle-aged adults. The more time people reallocated—up to two hours—the greater the benefit, with risk dropping as much as 43% in midlife.

But while the results are impressive, researchers caution that most trials were funded by drugmakers, long term safety data are still limited, and side effects such as nausea are common. Wed, 11 Feb 2026 10:01:13 EST https://www.sciencedaily.com/releases/2026/02/260211073033.htm https://www.sciencedaily.com/releases/2026/02/260207092904.htm A major study suggests menopause is linked to changes in brain structure, mental health, and sleep. Brain scans revealed grey matter loss in areas tied to memory and emotional regulation, while many women reported increased anxiety, depression, and fatigue. Hormone therapy did not reverse these effects, though it may slow age-related declines in reaction speed. Researchers say menopause could represent an important turning point for brain health. Sat, 07 Feb 2026 09:52:48 EST https://www.sciencedaily.com/releases/2026/02/260207092904.htm https://www.sciencedaily.com/releases/2026/02/260203030551.htm Popular weight-loss drugs like Ozempic and Wegovy can dramatically curb appetite, but experts warn many users are flying blind when it comes to nutrition. New research suggests people taking these medications may not be getting enough guidance on protein, vitamins, and overall diet quality, increasing the risk of muscle loss and nutrient deficiencies. Wed, 04 Feb 2026 10:43:08 EST https://www.sciencedaily.com/releases/2026/02/260203030551.htm https://www.sciencedaily.com/releases/2026/01/260128075359.htm Ozempic, Mounjaro, and Zepbound can drive impressive weight loss, but stopping them is often followed by rapid weight regain. Researchers found that people regain weight faster after quitting these drugs than after diet and exercise alone. Improvements in heart health and diabetes risk also tend to reverse within a few years. The results suggest long-term success may require more than medication alone. Wed, 28 Jan 2026 07:53:59 EST https://www.sciencedaily.com/releases/2026/01/260128075359.htm https://www.sciencedaily.com/releases/2026/01/260127010149.htm Researchers have discovered a biological switch that explains why movement keeps bones strong. The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting this “exercise sensor,” scientists believe they could create drugs that mimic exercise at the molecular level. The approach could protect fragile bones in people who are unable to stay active.

Scientists discovered that vibrating tendons before cycling allowed people to push harder without feeling like they were working more. Their muscles and hearts worked overtime, but their sense of strain stayed the same. This brain-body mismatch could one day help make exercise feel less intimidating, especially for people who struggle to stay active.

Researchers found that increased physical activity raises total energy use without triggering the body to conserve energy elsewhere. Basic functions keep running at full speed, even as movement increases. The result: exercise truly adds to your energy output rather than being metabolically “offset.” Thu, 01 Jan 2026 15:48:39 EST https://www.sciencedaily.com/releases/2025/12/251228020012.htm https://www.sciencedaily.com/releases/2025/12/251228020004.htm Weight loss restored healthy metabolism in both young and mid-aged mice, but the brain told a different story. In mid-aged animals, slimming down actually worsened inflammation in a brain region tied to appetite and energy balance. While this inflammation eventually subsided, brain inflammation has been linked to cognitive decline and neurodegenerative disease. The results suggest that weight loss in midlife may not be as straightforward as once thought.

A survey of women aged 40–60 who train regularly found high rates of sleep problems, exhaustion, anxiety, weight gain, and joint pain. Many athletes said these symptoms made it harder to train effectively or perform at their best. The results highlight a need for greater attention to menopause in active women.

Instead of setting speed or strength, it quietly enables movement in the background, much like oil in an engine. When scientists manipulated dopamine during movement, nothing changed—but restoring baseline dopamine levels made a big difference. The finding could reshape how Parkinson’s disease is treated.

Researchers found that surviving eye cells formed extra branches that restored communication with the brain. These new pathways worked much like the originals. The repair process, however, was slower or incomplete in females, pointing to important biological differences in recovery.

From misconceptions about heavy lifting and bed rest to confusion over posture, exercise, and surgery, Dr. Meghan Murphy breaks down what really causes pain and what actually helps. Her insights reveal that everyday habits, movement, and smart prevention often make a bigger difference than people realize.

Using advanced MRI-based brain-age estimates, scientists found that people with multiple healthy lifestyle factors had brains up to eight years younger than expected — even among those living with chronic pain.

Male mice showed strong inflammatory responses, while females showed none, yet both transmitted pain-inducing signals through their blood. These findings reveal previously unknown pathways driving pain, especially in females. The work points toward new opportunities for personalized chronic pain therapies.

Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive flexibility and low endocannabinoid levels also contributed to increased use. The results hint at possible early indicators of vulnerability to drug misuse.

By precisely rewriting tiny sections of DNA, scientists at UCL and Great Ormond Street Hospital created universal CAR T-cells capable of targeting the cancer without harming themselves—a long-standing challenge in T-cell–based therapies. Early trial results show deep, long-lasting remissions, including in patients who had exhausted standard treatment options.

Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to neurodegeneration and amyloid buildup. Surprisingly, blood tests detected these changes earlier than PET scans. The results point to obesity as a major, modifiable contributor to Alzheimer’s progression.
