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.

Breathing polluted air may do more than harm your lungs — it could also increase your risk of Alzheimer’s disease. In a sweeping study of nearly 28 million older Americans, researchers found that long term exposure to fine particle air pollution was linked to a higher likelihood of developing Alzheimer’s. The connection appeared to stem largely from pollution’s direct effects on the brain, rather than through related health conditions like hypertension or depression.

Scientists have created a blood test that can estimate when Alzheimer’s symptoms are likely to begin. By measuring a protein called p-tau217, the model predicts symptom onset within roughly three to four years. The protein mirrors the silent buildup of amyloid and tau in the brain long before memory loss appears. This advance could speed up preventive drug trials and eventually guide personalized care.

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.

A new human study has uncovered how the body naturally turns off inflammation. Researchers found that fat-derived molecules called epoxy-oxylipins rein in immune cells that can otherwise drive chronic disease. Using a drug to boost these molecules reduced pain faster and lowered harmful inflammatory cells. The discovery could pave the way for safer treatments for arthritis, heart disease, and other inflammation-related conditions.

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed. This loss has been linked to heart disease, cancer, Alzheimer’s, and shorter lifespans. Researchers suspect Y-less cells may grow faster and disrupt normal body functions. What seemed like a minor genetic quirk could actually be a major driver of age-related disease.

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 development, they found no meaningful differences between vaccinated and unvaccinated groups. Experts say the results provide strong reassurance about vaccine safety in pregnancy.

A single dose of human papillomavirus (HPV) vaccine provided protection comparable to the current standard of two doses. The findings suggest that single-dose vaccine regimens could effectively prevent HPV and the cancers it causes, most notably cervical cancer.

Stanford researchers have developed an AI that can predict future disease risk using data from just one night of sleep. The system analyzes detailed physiological signals, looking for hidden patterns across the brain, heart, and breathing. It successfully forecast risks for conditions like cancer, dementia, and heart disease. The results suggest sleep contains early health warnings doctors have largely overlooked.

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.
