Dec. 22, 2025 A new study shows dopamine isn’t the brain’s movement “gas pedal” after all. Instead of setting speed or strength, it quietly enables movement in the background, much like oil in an engine. When scientists manipulated dopamine during ...
Dec. 19, 2025 After injury, the visual system can recover by growing new neural connections rather than replacing lost cells. Researchers found that surviving eye cells formed extra branches that restored communication with the brain. These new pathways worked ...
Dec. 17, 2025 A missing brain molecule may be disrupting neural wiring in Down syndrome, according to new research. Replacing it in adult mice rewired brain circuits and improved brain flexibility, challenging the ...
Dec. 11, 2025 Researchers discovered that nerve injuries can alter the immune system throughout the body, and males and females react very differently. Male mice showed strong inflammatory responses, while females showed none, yet both transmitted pain-inducing ...
Dec. 11, 2025 Rats with naturally high stress levels were far more likely to self-administer cannabis when given access. Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive flexibility ...
Dec. 10, 2025 Obesity accelerates the rise of Alzheimer’s-related blood biomarkers far more rapidly than previously recognized. Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to ...
Dec. 10, 2025 A Virginia Tech study shows that ultra-processed foods may influence adolescents differently from slightly older young adults. Participants aged 18 to 21 ate more at a buffet and snacked even when not hungry after two weeks on an ultra-processed ...
Dec. 9, 2025 BISC is an ultra-thin neural implant that creates a high-bandwidth wireless link between the brain and computers. Its tiny single-chip design packs tens of thousands of electrodes and supports advanced AI models for decoding movement, perception, ...
Dec. 8, 2025 Deep-brain recordings showed that Mounjaro and Zepbound briefly shut down the craving circuits linked to food noise in a patient with severe obesity. Her obsessive thoughts about food disappeared as the medication quieted the nucleus accumbens, the ...
Nov. 28, 2025 Researchers found that repeated head impacts can disrupt a key system that helps the brain wash away waste. In professional fighters, this system initially seems to work harder after trauma, then declines over time. MRI scans revealed that these ...
Nov. 28, 2025 Long-term inhalation of toxic air appears to dull the protective power of regular workouts, according to a massive global study spanning more than a decade and over a million adults. While exercise still helps people live longer, its benefits shrink ...
Nov. 27, 2025 Warming up significantly improves muscle performance, particularly speed and power, by increasing muscle temperature. Both passive heat methods and light exercise warm-ups work, but mimicking the actual workout movements can offer extra benefits. ...

Dec. 24, 2025 A four–amino acid peptide called CAQK has shown powerful brain-protective effects in animal models of traumatic brain injury. Delivered through a standard IV, it zeroes in on injured brain tissue, ...
Dec. 15, 2025 New research shows that your brain’s “true age” can shift dramatically depending on how you live, with optimism, restorative sleep, stress management, and strong social support acting like ...
Dec. 15, 2025 Back pain is wrapped in persistent myths, but many are far from the truth. From misconceptions about heavy lifting and bed rest to confusion over posture, exercise, and surgery, Dr. Meghan Murphy ...
Dec. 14, 2025 Researchers used a deep learning AI model to uncover the first imaging-based biomarker of chronic stress by measuring adrenal gland volume on routine CT scans. This new metric, the Adrenal Volume ...
Dec. 11, 2025 A cutting-edge therapy using base-edited immune cells is offering a major breakthrough for patients with one of the toughest forms of blood cancer, T-cell acute lymphoblastic leukaemia. By precisely ...
Nov. 27, 2025 Scientists studying young adults with obesity discovered early indicators of brain stress that resemble patterns seen in cognitive impairment. The group showed higher inflammation, signs of liver ...
Nov. 25, 2025 Scientists found that high-flavanol foods can prevent the decline in blood vessel function that occurs after prolonged sitting. Even physically fit men weren’t protected unless they had consumed ...
Nov. 24, 2025 A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering ...
Nov. 21, 2025 Researchers found that hot tubs raise core body temperature more effectively than traditional or infrared saunas, leading to stronger boosts in blood ...
Nov. 18, 2025 Scientists are uncovering how GLP-1 drugs like Ozempic and Wegovy act on brain regions that control hunger, nausea, pleasure-based eating, and thirst. These discoveries may help create treatments ...

Nov. 17, 2025 Chronic pain might quietly push people toward developing high blood pressure—and the more widespread the pain, the greater the danger. A massive analysis of over 200,000 adults uncovered strong ...
Nov. 14, 2025 Researchers uncovered how fatty molecules called ceramides trigger acute kidney injury by damaging the mitochondria that power kidney cells. By altering ceramide metabolism or using a new drug ...
Nov. 11, 2025 Researchers found that runners who sleep poorly face nearly double the injury risk compared to those who rest well. The study highlights that sleep is not just recovery—it’s a key factor in ...
Nov. 10, 2025 Scientists have discovered that most chronic fatigue patients experience dysfunctional breathing, which may worsen their symptoms. The likely culprit is dysautonomia, a disruption in how the body ...
Nov. 11, 2025 Researchers in Osaka have found that stem cells from fat tissue can repair spinal fractures similar to those caused by osteoporosis. By turning these cells into bone-forming clusters and pairing them ...
Nov. 3, 2025 Boston researchers linked nighttime light exposure to greater stress-related brain activity and inflamed arteries, signaling a higher risk of heart disease. The study suggests that artificial light ...
Nov. 16, 2025 GLP-1 drugs like tirzepatide and semaglutide offer powerful weight-loss effects but come with unanswered questions about long-term safety, side effects, and global accessibility. Researchers stress ...
Nov. 3, 2025 Disrupted sleep patterns in Alzheimer’s disease may be more than a symptom—they could be a driving force. Researchers at Washington University found that the brain’s circadian rhythms are ...
Nov. 13, 2025 Ultra-endurance athletes can push their bodies to extraordinary extremes, but even they run into a hard biological wall. Researchers tracked ultra-runners, cyclists, and triathletes over weeks and ...
Oct. 20, 2025 A sweeping review of over 200 studies finds that aerobic exercises like walking and cycling offer the best pain relief and mobility gains for knee osteoarthritis. Compared to other types of exercise, ...
Oct. 14, 2025 Endurance exercise may train the immune system as much as the muscles. Older adults with decades of running or cycling had immune cells that functioned better and aged more slowly. Their inflammation ...
Oct. 10, 2025 Scientists have pinpointed Y1 receptor neurons in the brain that can override chronic pain signals when survival instincts like hunger or fear take precedence. Acting like a neural switchboard, these ...
Oct. 5, 2025 Stanford scientists found that aging disrupts the brain’s internal navigation system in mice, mirroring spatial memory decline in humans. Older mice struggled to recall familiar locations, while a ...
Oct. 2, 2025 Penn researchers found that psilocybin can calm brain circuits tied to pain and mood, easing both physical suffering and emotional distress in animal studies. The compound works in the anterior ...
Nov. 1, 2025 New research from Australia overturns the old idea that exercise “uses up” heartbeats. It shows that fitter people actually use fewer total heartbeats each day thanks to their lower resting heart ...
Oct. 6, 2025 A major study from Tübingen found that prediabetic individuals who normalized their blood sugar through healthy habits — even without shedding pounds — cut their risk of type 2 diabetes by 71%. ...
Oct. 15, 2025 Korean researchers found that low-dose radiation therapy eased knee pain and improved movement in people with mild to moderate osteoarthritis. The treatment, far weaker than cancer radiation, showed ...
