Oxidative stress linked to repetitive behaviors in mice

Abnormal repetitive behaviors in mice are strongly linked to multiple biomarkers of oxidative stress, which occurs when antioxidants cannot counteract the effects of harmful molecules in the body, according to a study published November 5, 2025, in the open-access journal PLOS One by Kendall Coden and Dr. Joseph Garner of Stanford University, U.S.

Heated tobacco and cigarettes cause the same gut and vascular damage, study finds

Italian researchers found that both heated tobacco products (HTPs) and conventional cigarettes trigger oxidative stress, endotoxemia, and gut barrier disruption in adults and children. The findings challenge the perception that HTPs are a safer alternative to smoking.

Does fasting earlier in the day improve metabolism? This study says no

In a randomized crossover trial of 31 women with overweight, early and late time-restricted eating (TRE) produced no improvement in insulin sensitivity or cardiometabolic markers under isocaloric conditions. Both schedules, however, shifted internal circadian clocks, highlighting that meal timing affects biological rhythms more than metabolic outcomes.

Eating habits tied to Parkinson’s risk: sweets and processed meats raise odds, fruit lowers them

In a large Italian case-control study, researchers identified data-driven dietary patterns linked to Parkinson’s disease risk. Diets rich in sweets, red and cured meats were associated with higher odds of PD, while fruit, especially citrus, was protective.

Prenatal air pollution exposure tied to higher autism risk in children

A population-based study of over two million births in Ontario found that prenatal exposure to the sulfate and ammonium components of fine particulate matter (PM₂.₅) was associated with a higher risk of autism spectrum disorder. The risk was greatest during mid to late pregnancy and among infants in urban, lower-income neighborhoods.

Mediterranean diet linked to dramatically lower odds of endometriosis

A new case–control study found that women with stronger adherence to the Mediterranean diet had dramatically lower odds of endometriosis. Diets rich in fruits, vegetables, fish, and legumes were protective, while higher intakes of meat, dairy, and refined whole grains were linked to increased risk.
