The gut microbiome, consisting of trillions of microorganisms in the digestive tract, plays a central role in overall health, influencing digestion, immunity, metabolism, mental well-being, and even skin condition. In 2025, research has emphasized personalized approaches, highlighting how individual microbiomes vary and respond differently to interventions. This has led to advancements in targeted therapies and a deeper understanding of the gut-brain-skin axis, where microbial balance affects mood, cognition, and dermatological health. Emerging studies also link microbiome alterations to conditions like Alzheimer's disease, with gut bacteria influencing inflammation and brain biomarkers. Key Research Highlights for 2025 Research in 2025 has focused on translating microbiome science into practical health applications, with emphasis on resilience, personalization, and community-driven studies.  Here's a summary of major developments:  Personalized and Next-Generation Biotics: At...

Cells contain specialized organelles called mitochondria that are responsible for cellular energy production. Mitochondria generate adenosine triphosphate (ATP), which functions as the primary energy molecule used by cells to power essential biological processes (1), including muscle contraction and nerve signal transmission. Mitochondria can metabolize both glucose and fats to produce ATP through a series of biochemical reactions. However, research indicates that glucose serves as the most efficient and versatile substrate for mitochondrial ATP synthesis, as the metabolic pathways involving glucose yield more ATP per molecule of oxygen consumed compared to fatty acid oxidation. (2,3,4,5,6,7,8,9,10) To understand why glucose shines so brightly as a fuel source, it helps to zoom in on a few key concepts: how glucose delivers energy, why its metabolic "exhaust" tends to be less stressful on your cell’s machinery, and how relying on other fuels like fats can introduce imbalances...

Exercise really is as good as a drug, a groundbreaking new study found. In a global trial, workouts did better than pricey chemotherapy to prevent colon cancer recurrence. Oncologists gathered at the biggest annual cancer meeting in June gave the news a standing ovation. For over a decade, the medical community has recognized that exercise may improve cancer outcomes. One of the earliest clinical indications came from the Nurses’ Health Study in 2006, which showed that substantial and sustained weight loss over several years was associated with a lower incidence of postmenopausal breast cancer ( JAMA 2006 ). In the years since, numerous preclinical and observational studies have supported the idea that physical activity can positively influence cancer outcomes. However, definitive level 1 evidence has remained elusive. Scientists and doctors often joke that exercise is one of the best drugs we have. But can a workout truly rival chemotherapy in...

Abstract Background: Integrative oncology increasingly incorporates repurposed drugs like ivermectin, mebendazole, and atovaquone to complement conventional cancer therapies by targeting drug resistance, tumor hypoxia, and immunologic evasion. This systematic review synthesizes current clinical and mechanistic evidence supporting these agents and highlights ongoing clinical trials and future perspectives in 2025. Methods: A systematic literature search was conducted on PubMed, PMC, clinical trial registries, and oncology integrative medicine sources from 2018 through 2025 for studies addressing ivermectin, mebendazole, and atovaquone in cancer treatment. Eligible studies included in vitro, in vivo, and clinical trials with relevant mechanistic insights and clinical outcomes. Evidence was appraised for quality and strength of recommendation in integrative oncology context. Results: Ivermectin displays multimodal anticancer effects including mitochondrial inhibition, reversal of mu...
