Coffee, tea and dementia risk: Why the amount you drink could matter

A targeted perspective synthesizes epidemiological and mechanistic evidence examining how caffeine consumption during midlife may influence dementia risk later in life. The authors highlight potential roles for dose, age, CYP1A2 genotype, adenosine signaling and cultural drinking practices, while stressing that current observational evidence cannot establish causality.

Neurogenesis stalls in the brains of adults with major depressive disorder, study shows

Most of our brain's 100 billion neurons are created before we're born, but the trickle of neurons created in the adult brain hippocampus could be instrumental in preventing depression, suggest findings from a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons.

Lower-calorie meals look cheaper, but there’s a catch in the price

Analysis of 7,392 menu items from 200 large restaurant chains found that lower-calorie options on two major UK food delivery platforms carried a substantially higher cost per 100 kcal than higher-calorie items. The findings suggest that per-calorie pricing may create financial disincentives for choosing lower-calorie foods, with potential implications for diet-related health inequalities.

A New York skincare survey found mercury where consumers might not expect it

Targeted surveillance of 197 skin-lightening and skincare products purchased in New York City from 2009 to 2022 found detectable mercury in 29%, with 18% exceeding the FDA’s 1 ppm limit and concentrations reaching 27,000 ppm. All mercury-positive products were manufactured abroad, mercury was rarely disclosed on labels, and the findings highlight regulatory, health-equity, and environmental justice concerns.

Your sleep and stress may be connected in a more complicated way than expected

A seven-day intensive longitudinal study of 106 university students found little evidence that higher-than-usual daytime stress predicted poorer sleep that night. In contrast, better-than-usual subjective sleep was followed by lower perceived stress the next day, while objective sleep associations were generally weak and uncertain.

Live tracking reveals how robotic surgery impacts surgeon stress

Robot-assisted surgery (RAS) is one of the most advanced tools in modern medicine. These systems give surgeons extreme precision, allowing procedures to be performed through small incisions that minimize both pain and recovery time.

Large US trial supports silver diamine fluoride for severe early childhood caries

A phase 3 randomized trial of 830 young children with severe early childhood caries found that 38% silver diamine fluoride arrested 54.0% of eligible cavitated dentin lesions at six months, compared with 22.5% after placebo. The noninvasive treatment showed clinically meaningful efficacy, but about half of the lesions remained active, supporting close monitoring and additional preventive care.

Different cyclone definitions reveal uneven diarrheal disease risks across Asia

Tropical cyclone links to diarrheal disease varied widely across ten Asian regions, depending on how cyclone exposure was defined and whether mortality or morbidity was measured. Mortality associations were mostly uncertain, while morbidity patterns differed by region, with Taiwan showing the largest attributable burden.
