|  | | | | |  Gaining weight before age 30 tied to higher mortality The study reveals that weight gain before 30 years is associated with increased mortality risk, underscoring the need for early obesity intervention strategies. | |  | | | | |  Large US study finds never-married adults face higher risk for most major cancers A large US population-based study found that never-married adults had higher cancer incidence than ever-married adults across most cancer types, with the largest disparities seen in older adults and in Black men. The pattern was especially strong for HPV-related, tobacco-related, and several reproductive cancers, suggesting marital status may act as an important social marker of cancer risk. | | | | | | |  Higher optimism may lower dementia risk in older adults Higher optimism in adults aged 70 and older was associated with a lower risk of developing dementia over up to 14 years of follow-up in the Health and Retirement Study. The association remained after adjustment for demographic factors, depression, health conditions, smoking, and physical activity, although the study was observational and cannot prove causation. | | | | | | |  Beetroot supplement raises nitric oxide markers in triathletes after one week A randomized cross-over pilot study in 10 amateur male triathletes found that a beetroot-based multi-ingredient nitrate supplement increased nitric oxide-related and redox biomarkers over 7 days without evidence of lipid oxidative damage. The supplement was generally well tolerated, but the study did not measure whether these biochemical changes improved performance or recovery. | |

|  | | | A new randomized clinical trial found that men with localized, intermediate‑risk prostate cancer recovered faster and experienced less short‑term impact on their daily lives when treated with MRI‑guided, transurethral ultrasound ablation (TULSA) compared with robotic prostate surgery. | | | | |  Early-onset cancers are rising worldwide, and this Cell Perspective argues that cancer prevention must move beyond static risk-factor snapshots toward life-course exposure mapping, tissue-level biology, and dynamic estimates of preventability. The authors propose three linked frameworks to speed discovery of cancer causes and translate those findings into more precise prevention and interception strategies. | | | | |  A 12-week single-blind trial in 38 Japanese adults found that daily Fuji apple intake did not significantly change overall host metabolic markers, but responses differed by baseline gut enterotype. Participants in the Bacteroidaceae-dominant enterotype showed significant increases in fecal short-chain fatty acids after apple consumption, suggesting that gut microbiota structure may shape functional dietary responses. | | | | |  A mouse study in Frontiers in Nutrition found that parental sucralose and stevia intake altered gut microbiota, short-chain fatty acids, and gene expression across generations, with sucralose showing the stronger and more persistent effects. The changes were transmitted to offspring not directly exposed to the sweeteners, although several effects were attenuated by the F2 generation. | | | | |  A long-running UK cohort study found that exposure to parental depression from pregnancy through young adulthood was linked to higher odds of depression and anxiety in adult offspring. Maternal depression in late pregnancy was uniquely associated with later psychotic symptoms, while paternal associations emerged more clearly from mid-childhood onward. | | | | |  Researchers found that cola exposure quickly lowered pH and altered the microbiome on the inner surface of clear aligners, with the greatest disruption observed when aligners were removed before drinking and then reinserted. In this small 24-hour study, wearing aligners during exposure appeared less disruptive than removing them, though the authors said the mechanism still needs further study. | | | | |  In a systematic review and meta-analysis, researchers found that occupational exposure to talc that is not contaminated with asbestos is not associated with an increase in the risk of lung cancer, mesothelioma, or laryngeal cancer. | | | | |  Super-enhancers (SEs) are large clusters of transcriptional regulatory elements that drive oncogene expression, maintain malignancy, and create "transcriptional addiction" in cancer. | | | | |  A global study reveals a sharp rise in metabolic syndrome prevalence from 2000 to 2023, highlighting urgent public health challenges and regional disparities. | | | | |  Cancer stem cells (CSCs), a critical subpopulation within tumors, drive cancer initiation, progression, metastasis, relapse, and resistance to therapy due to their innate capacity for self-renewal and differentiation. | | | | |  New research shows that the threat-response in the brain's amygdala (which processes emotions) is linked to different patterns of drinking by sex. | |
