 | | |  Elite athletes with higher vitamin D show healthier lipid profiles Higher serum 25-hydroxyvitamin D levels were independently associated with lower LDL-C, triglycerides, and lipoprotein(a) in 773 male professional athletes. The cross-sectional study cannot establish causality, but it suggests that vitamin D status may be linked to cardiovascular risk-related lipid markers, even in elite athletic populations. | | | | |  Synthetic gut communities reveal how diet rewires the microbiome Synthetic microbial communities give researchers controlled models for testing how diet reshapes gut microbial ecology, metabolism, and host-relevant responses. The review highlights how SynComs can strengthen causal inference, improve intervention testing, and support future precision nutrition, while noting major challenges in stability, standardization, and ecological realism. | |

|  | | | | |  Breast milk nutrient boosts long-term immune system development Trans-vaccenic acid (TVA), the most abundant trans fatty acid found in human breast milk, helps boost immune system development and has long-lasting effects on immune system health in mice, according to a new study by researchers from the University of Chicago. | |  | | | | |  Resistance training reduces major heart disease risk for active women Women who lift weights may have a lower risk of major heart disease, especially when combined with aerobic exercise, according to a new study published today in JACC, the flagship journal of the American College of Cardiology. | | | | | | |  Study links menopause and hormone therapy status to modifiable health behaviors Menopause is associated with a number of adverse health effects, some of which can be mitigated by an array of modifiable health behaviors (MHBs), including diet, exercise, and sleep duration. | |

| | | |  A new Simon Fraser University study has found men in ancient Europe likely had better access to protein-rich foods than women did. | | | | |  Imagine if a doctor could look at your DNA and predict not just your disease risk, but also which foods you're drawn to – and whether those cravings are quietly protecting you. | | | | |  A new study led by researchers at The University of Texas at El Paso found that use of weight loss drugs like Ozempic and other GLP-1s is associated with a lower risk of developing alcohol, opioid, nicotine and cocaine use disorders. | | | | |  Americans spend more than $1 billion annually on fish oil supplements, in part due to purported cognitive benefits from the omega-3 fatty acids they contain, essential nutrients that help form brain cell connections needed for cognition. | | | | |  New research links childhood adversity to mitochondrial bioenergetic changes later in life, underscoring the impact of stress in early life on cellular health. | | | | |  The world's first HIV-positive-to-HIV-positive lung transplant was performed at NYU Langone Health. | | | | |  Pheno Therapeutics Limited. (Pheno), a clinical stage biotechnology company focused on the discovery and development of small molecule therapeutics for the treatment of neurological diseases, today announced that the US Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for PTD802, the Company's lead therapeutic candidate. | | | | |  This review describes how gut microbial messengers, including SCFAs, microbiota-modified bile acids, neuroactive metabolites, and extracellular vesicles, may shape obesity and type 2 diabetes through the microbiota-gut-brain axis. | | | | |  Cancer is often considered a disease of aging. Older adults are at higher risk because they have had more time to accumulate cellular damage that can trigger tumor formation. | | | | |  Microplastics – minuscule pieces of plastic broken down from larger plastic waste – are a growing concern for human health, especially for the liver. | | | | |  Nearly all Michiganders age 50 and over say it's very important to keep their brains healthy as they grow older, a new poll finds. | | | | |  A scoping review of 140 empirical studies found that human-AI collaboration in healthcare reports the most consistent benefits in diagnostic interpretation, especially when AI supports bounded tasks and clinicians retain final responsibility. Evidence remains fragmented across triage, treatment planning, and documentation, with few studies measuring patient outcomes, system impact, trust calibration, or governance in real-world settings. | | | | |  A narrative review found that tight-fitting underwear may modestly raise scrotal temperature and is inconsistently linked to lower sperm production measures. However, current evidence does not show that switching to looser underwear improves real-world fertility outcomes. | | | | |  A new study from Michigan State University found increases in binge eating when taking hormone pills in the form of oral contraceptives - but not in all women. | |
