A pack-a-day smoker can spend around $14,000 a year on cigarettes, yet despite the financial and health costs, quitting remains one of the most difficult changes many people will ever attempt.

Integrating scents into virtual reality may reduce negative emotions in isolated environments, but more research is needed for sustained psychological benefits.

The study highlights the relationship between weather and mental health care use, suggesting routine weather patterns could forecast service demand effectively.

A Dutch dietary modeling study found that replacing major animal-based protein sources with plant-based substitutes reduced protein, EAA, vitamin, and mineral intake across age groups. Older adults, adolescents, children, and women were especially vulnerable to shortfalls, highlighting the need for planned substitutions, fortified foods, and age-specific dietary guidance.

Researchers followed 79 U.S. adults for 70 days and found that daily lifestyle behaviors clustered with positive and negative affect across same-day, next-day, and between-person patterns. Person-specific networks showed that these daily habits and mood links varied widely, suggesting future lifestyle interventions may need to be more personalized.

Domestic and family violence (DFV) rates in the Indo-Pacific are among the highest globally, but there is a lack of focus, both in research and policy, on the issue across the region.

As human cases of flea-borne murine typhus continue to occur in South Texas, researchers are working to better understand the role cats and their fleas may play in the disease's transmission cycle.

A Perspective review in npj Science of Food argues that pandemics can weaken food safety systems even when the pathogen is not foodborne. The authors call for One Health planning that integrates food safety into pandemic preparedness, surveillance, laboratory capacity, workforce readiness, and regulation.

In almost half of all fatal electric scooter crashes in Sweden, the rider has been under the influence of alcohol.

A major international clinical trial led by Queen Mary University of London and Uppsala University in Sweden has found that an emerging type of hip replacement implant dramatically reduces complications in people with a broken hip.

No rodents were found aboard. The confined vessel, carrying 147 people from 23 countries, became an unexpected amplifier of person‑to‑person transmission.

Mental health conditions such as anxiety and depression affect millions of people across Europe and are increasingly recognised as closely linked to diet, nutrition, social inequalities and broader lifestyle factors.

New research from Liverpool School of Tropical Medicine (LSTM) has highlighted the need to test millions of women and girls for female genital schistosomiasis (FGS), a neglected disease that can increase the risk of chronic illness, HIV and cervical cancer.

Blood-based circular RNAs showed strong potential for identifying biomarker-confirmed Alzheimer’s disease and predicting progression to symptomatic disease. When combined with pTau217, the circRNA model produced the strongest predictive performance, but larger prospective validation is still needed.

Researchers with the Charbonneau Cancer Institute at the University of Calgary and McMaster University have identified a unique target present on a specific group of solid cancerous tumors.

Psychological stress is increasingly recognized as a risk factor for certain health conditions including cardiovascular disease and diabetes, especially when paired with an impaired immune response.

Nutritional imbalance during pregnancy can have long-lasting effects on the health status and disease susceptibility of the offspring.

A new Mayo Clinic study shows that integrating telomere length evaluation and genetic testing into pulmonary care can significantly change how physicians diagnose and treat pulmonary fibrosis - in some cases even redirecting the course of care.

Researchers have uncovered a previously unrecognized pathway linking lung tumor genetics, diet, and the nervous system that drives cancer-associated cachexia, according to a new study in mice.

New research has found that digital breast tomosynthesis (DBT) availability at breast imaging facilities is similar across low- and high-deprivation areas, but facilities in low-deprivation areas are significantly more likely to offer weekend appointments, which may impact access for traditionally underserved populations.
