 | | |  The long and short of it: Human penis size evolved for both attraction and rivalry, study suggests This experimental study used life-sized and screen-based 3D male avatars to test how penis size, height, and body shape influence female mate choice and male assessments of rivals. The findings show non-linear female preferences for size and demonstrate that penis size functions as a modest but significant cue in male perceptions of fighting ability, alongside stronger traits such as height and torso shape. | | | | |  Men still develop heart disease 10 years earlier than women Historical data indicate that men develop coronary heart disease (CHD) 10 years before women. A recent study in the Journal of the American Heart Association indicates that this sex gap still remains. | | | | |  New trial tests strategies to protect heart health during prostate cancer therapy City of Hope, one of the largest and most advanced cancer research and treatment organizations in the United States with its National Medical Center ranked among the nation's top cancer centers by U.S. News & World Report, has opened a phase 2 clinical trial comparing three different strategies for protecting heart health in prostate cancer patients who receive androgen deprivation therapy (ADT), a potentially lifesaving hormone therapy. | |

|  | | | | |  Following the EAT-Lancet diet lowers chronic kidney disease risk Research shows the EAT-Lancet diet may lower chronic kidney disease risk, emphasizing the importance of diet quality and personalized nutrition in prevention. | |  | | | | |  Why exercise is essential for restoring fitness after GLP-1-based weight loss This randomized controlled trial shows that structured moderate-to-vigorous exercise, alone or combined with liraglutide, improves physical function and cardiorespiratory fitness after diet-induced weight loss in adults with obesity. In contrast, liraglutide alone sustains weight loss but does not significantly improve measured physical fitness outcomes. | | | | | | |  Eating melatonin-rich foods is linked to lower obesity and depression rates This cross-sectional analysis of 8,320 Brazilian adults quantified melatonin intake from habitual diets and examined associations with multiple chronic health outcomes. Higher dietary melatonin intake was inversely associated with obesity and depression in a non-linear pattern, with no significant associations observed for other conditions. | | | | | | |  Three daily servings of full-fat dairy do not worsen weight or blood markers This randomized 12-week trial examined whether adding three daily servings of full-fat dairy to diets aligned with Canada’s Food Guide affects body weight, cardiometabolic markers, and nutrient intake in adults with overweight or obesity. Full-fat dairy intake did not adversely affect weight, body composition, or metabolic health and increased calcium and protein intake, supporting dietary compatibility rather than therapeutic benefit. | |

| | | |  Oat consumption boosts gut microbiota-derived phenolic metabolites, driving cholesterol-lowering effects and improving lipid metabolism in metabolic syndrome. | | | | |  Modern lifestyle factors such as circadian disruption, sleep deprivation, stress, and exercise reshape the gut bacteriome and its metabolic outputs. These microbiome changes are linked to immune, metabolic, and cancer-related pathways, largely through evidence from animal models and observational human studies. | | | | |  Lifetime alcohol intake, not just recent drinking, is associated with colorectal cancer risk in older adults followed in the PLCO Cancer Screening Trial. Heavy and consistent long-term drinking was linked to higher colorectal cancer risk, while alcohol cessation was associated with lower odds of early, nonadvanced adenomas. | | | | |  Research indicates the herpes zoster vaccine may reduce dementia rates by 2%, highlighting its potential role in promoting brain health in aging populations. | | | | |  The study reveals that moderate coffee consumption may lower atrial fibrillation recurrence risk post-cardioversion, highlighting coffee's potential benefits. | | | | |  How camel milk’s unique proteins and bioactive compounds are reshaping scientific understanding of dairy nutrition, while revealing where the evidence is strong and where more research is still needed. | | | | | People with type 2 diabetes face a higher risk of heart attacks, strokes and other cardiovascular problems, according to the National Institutes of Health. | | | | |  Findings suggest that plant-sourced nitrates may reduce dementia risk, while animal and water sources are linked to increased risk, emphasizing diet quality. | | | | | Because treatment of the whole prostate can lead to long-term side effects in patients with prostate cancer, interest in minimally invasive, focal treatment options has been growing for certain patients. | | | | |  National data indicates that lowering alcohol consumption could prevent thousands of cancer deaths, emphasizing the importance of public health interventions. | | | | |  A team of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER) and the University of Seville, in collaboration with the Virgen Macarena University Hospital, have identified a fundamental mechanism that links the 24-hour circadian cycle to the precise repair of DNA breaks. | | | | |  The LA produce prescription program significantly improved nutrition security among Medicaid patients with diabetes, revealing ongoing affordability barriers. | |
