Aging doesn’t just add fat—it redistributes it in risky ways, pushing more into the abdomen where it can harm health. Scientists found that testosterone plays a key role in this shift. In older women recovering from hip fractures, a...
Scientists have developed a breakthrough injectable biomaterial that travels through the bloodstream to repair damaged tissue from within, reducing inflammation and jumpstarting healing. In animal studies, it successfully treated heart...
Fish oil has long been praised as brain-boosting, but new research suggests the story may be more complicated. Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil—EPA—may actually...
A surprising new study suggests that eating a very healthy diet—packed with fruits, vegetables, and whole grains—might be linked to a higher risk of lung cancer in younger non-smokers. Researchers found that patients under 50 diagnosed...
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...
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...
New fathers appear to have fewer mental health diagnoses during pregnancy and the early months after birth. But that early stability does not last. About a year later, depression and stress-related disorders increase significantly,...
“Forever chemicals” may be affecting kids in ways that last a lifetime. A new study links early PFAS exposure to lower bone density during the teen years, especially in girls. Researchers also found that when exposure happens may play a...
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...
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...
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...
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...
Scientists have revealed how the body’s microscopic cold sensor, TRPM8, detects both chilly temperatures and the cooling effect of menthol. The discovery finally shows how the sensation of “cool” works at the molecular level—and could...
That photogenic cup of bubble tea may come with hidden downsides. 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...
Scientists are taking a closer look at the pill forms of Wegovy and Ozempic. In an animal study, the ingredient SNAC, which helps semaglutide survive the stomach and enter the bloodstream, was associated with changes in gut bacteria,...
Heart disease is on track to tighten its grip on American women. 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...
Worrying about getting older—especially fearing future health problems—may actually speed up aging at the cellular level, according to new research from NYU. In a study of more than 700 women, those who felt more anxious about aging...
Babies born in the early 2000s were exposed in the womb to far more “forever chemicals” than researchers once realized, according to a new study. By using advanced chemical screening on umbilical cord blood, scientists detected 42...
Researchers tested whether generative AI could handle complex medical datasets as well as human experts. In some cases, the AI matched or outperformed teams that had spent months building prediction models. By generating usable...
Sugary drinks may be linked to more than just physical health problems in teens. A new review of multiple studies found a consistent association between high consumption of beverages like soda, energy drinks, sweetened juices, and...
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...
Researchers tracked more than 400 toddlers to see whether mRNA COVID-19 vaccination during or just before pregnancy was linked to autism or developmental delays. After detailed assessments of speech, motor skills, behavior, and social...
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...
Autism has long been thought of as a condition that mostly affects boys, but a massive study from Sweden suggests that idea may be misleading. Tracking nearly 3 million people over decades, researchers found that while boys are diagnosed...
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,...
People who naturally stay up late may be putting their hearts under added strain as they age. A large study tracking more than 300,000 adults found that middle-aged and older night owls had poorer overall heart health and a higher risk...
Men start developing heart disease earlier than women, with risks rising faster beginning around age 35, according to long-term research. The difference is driven mainly by coronary heart disease, not stroke or heart failure. Traditional...
A large, decades-long study suggests that signs of ADHD in childhood may have consequences that extend well beyond school and behavior. Researchers followed nearly 11,000 people from childhood into midlife and found that those with...
Scientists at Stanford Medicine have discovered a treatment that can reverse cartilage loss in aging joints and even prevent arthritis after knee injuries. By blocking a protein linked to aging, the therapy restored healthy,...
A major new scientific review brings reassuring news for expectant parents: using acetaminophen, commonly known as Tylenol, during pregnancy does not increase a child’s risk of autism, ADHD, or intellectual disability. Researchers...
MIT engineers have developed a pill that can wirelessly report when it’s been swallowed. Inside the capsule is a biodegradable antenna that sends a signal within minutes of ingestion, then safely dissolves. The system is designed to work...
Teens who sleep in on weekends may be giving their mental health a boost. A new study found that young people who made up for lost weekday sleep had a significantly lower risk of depression. While consistent sleep is still best, weekend...
Scientists have found that combining silybin with carvedilol works far better against liver fibrosis than either drug alone. The duo targets the root drivers of liver scarring, sharply reducing collagen buildup and liver damage in...
Researchers compared a traditional Chinese medicine, Yueju Pill, with a standard antidepressant and found both reduced depression symptoms. However, only Yueju Pill increased a brain-supporting protein associated with mood improvement....
A groundbreaking study shows that breast cancer screening works better when it’s personalized. Instead of annual mammograms for all, women were screened based on genetics, health history, and lifestyle factors. This approach reduced...
As spinal cord injuries increasingly affect older adults, new research reveals a surprising pattern in recovery. The study shows that aging does not appear to slow the healing of nerves themselves, with older patients regaining strength...
A one-dose oral drug called zoliflodacin has proven highly effective against gonorrhoea in a major international trial. The pill matched the success of current treatments while avoiding injections and complex dosing. As antibiotic...
Stanford scientists have uncovered how mRNA COVID-19 vaccines can very rarely trigger heart inflammation in young men — and how that risk might be reduced. They found that the vaccines can spark a two-step immune reaction that floods the...
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, calming inflammation and reducing cell...
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...
Natural killer cells act as the immune system’s rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that both conditions were linked to...
Researchers discovered that tanning beds cause widespread, mutation-laden DNA damage across almost all skin, explaining the sharply increased melanoma risk. Single-cell genomic analysis revealed dangerous mutations even in sun-protected...
Researchers discovered that children who went back to school during COVID experienced far fewer mental health diagnoses than those who stayed remote. Anxiety, depression, and ADHD all declined as in-person learning resumed. Healthcare...
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...
