- newThe invisible microbes that help keep us healthy
Not all microbes are villains—many are vital to keeping us healthy. Researchers have created a world-first database that tracks beneficial bacteria and natural compounds linked to immune strength, stress reduction, and resilience. The findings challenge the long-standing obsession with germs as threats and instead highlight the hidden health benefits of biodiversity. This shift could influence everything from urban design to environmental restoration.

- newA smarter way to screen for breast cancer is emerging
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 advanced cancers without increasing risk for those screened less often. Most women preferred the personalized model, hinting at a major shift in future screening guidelines.

- newBreakthrough obesity drugs are here but not for everyone
UK experts are warning that access to new weight-loss drugs could depend more on wealth than medical need. Strict NHS criteria mean only a limited number of patients will receive Mounjaro, while many others must pay privately. Researchers say this risks worsening existing health inequalities, especially for groups whose conditions are often missed or under-diagnosed. They are calling for fairer, more inclusive access before gaps in care widen further.

- newType 2 diabetes physically changes the human heart, study finds
Type 2 diabetes doesn’t just raise the risk of heart disease—it physically reshapes the heart itself. Researchers studying donated human hearts found that diabetes disrupts how heart cells produce energy, weakens the muscle’s structure, and triggers a buildup of stiff, fibrous tissue that makes it harder for the heart to pump. These changes are especially severe in people with ischemic heart disease, the most common cause of heart failure.

- newScientists found a way to help aging guts heal themselves
Researchers have discovered a way to help aging intestines heal themselves using CAR T-cell therapy. By targeting senescent cells that build up over time, the treatment boosted gut regeneration, reduced inflammation, and improved nutrient absorption in mice. It even helped protect the intestine from radiation damage, with benefits lasting up to a year. Early results in human intestinal cells suggest the approach could one day improve gut health in older adults and cancer patients.

- A weak body clock may be an early warning for dementia
Your daily rhythm may matter more for brain health than previously thought. Older adults with weaker, more disrupted activity patterns were far more likely to develop dementia than those with steady routines. A later daily energy peak was also linked to higher risk. The study points to the body clock as a possible early warning sign for cognitive decline.

- The hidden timing system that shapes how you think
The brain constantly blends split-second reactions with slower, more thoughtful processing, and new research shows how it pulls this off. Scientists discovered that brain regions operate on different internal clocks and rely on white matter connections to share information across these timescales. The way this timing is organized affects how efficiently the brain switches between activity patterns tied to behavior. Differences in this system may help explain why people vary in cognitive ability.

- Scientists tested intermittent fasting without eating less and found no metabolic benefit
Time-restricted eating has been widely promoted as a simple way to boost metabolic health, but new research paints a more complicated picture. When calorie intake stayed the same, an eight-hour eating window did not improve insulin sensitivity or cardiovascular markers. What did change was the body’s internal clock, which shifted based on meal timing and altered sleep patterns. The results suggest calorie reduction, not the eating window itself, may be the real driver of health benefits.

- Age does not stop nerve healing after spinal cord injury
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 and sensation at rates similar to younger people. However, age makes a clear difference in how well people recover everyday abilities like walking, mobility, and self-care.

- New antibiotic pill shows promise against drug-resistant gonorrhea
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 resistance spreads, this new option could make treatment simpler and more accessible worldwide. Approval could mark a major step forward in controlling a stubborn global STI.

- Scientists discover why mental disorders so often overlap
A massive global genetics study is reshaping how we understand mental illness—and why diagnoses so often pile up. By analyzing genetic data from more than six million people, researchers uncovered deep genetic connections across 14 psychiatric conditions, showing that many disorders share common biological roots. Instead of existing in isolation, these conditions fall into five overlapping families, helping explain why depression, anxiety, PTSD, bipolar disorder, schizophrenia, and substance u…

- A hidden brain problem may be an early warning for Alzheimer’s
Researchers discovered that clogged brain “drains” show up early in people at risk of Alzheimer’s disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some cases, they may signal Alzheimer’s earlier than other commonly used brain markers. This could help physicians detect the disease earlier, before irreversible damage sets in.

- Menopause symptoms are common even in elite endurance athletes
Menopause symptoms are common among female endurance athletes and often interfere with training and performance. 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.

- Diabetes drugs may be changing cancer in surprising ways
Common diabetes drugs may do more than regulate blood sugar—they could also influence how cancers grow, spread, or slow down. Researchers are now unraveling how these medications affect immune function, inflammation, and tumor biology, with intriguing but still uncertain implications.

- A new gel could help people get their voices back
A new gel developed by McGill researchers could change how vocal cord injuries are treated. The injectable material lasts far longer than current options, staying intact for weeks instead of breaking down quickly. By acting like a molecular glue, it gives damaged vocal cords more time to heal. The team hopes it could eventually lead to a gentler, longer-lasting treatment for voice loss.
