Ancient DNA analysis of 4000-year-old skeletons in Chile suggests leprosy, caused by Mycobacterium lepromatosis, existed in the Americas long before European colonization. This challenges existing views.
Japanese scientists discovered that vitamin C enlarges skin by activating genes for cell growth, reversing age-related thinning. It reactivates DNA, promoting skin renewal and repair. This offers a treatment for aging skin.
MERS-related bat viruses, particularly HKU5, may be one mutation away from infecting humans, posing a pandemic threat. Research reveals their ACE2 receptor binding and potential for adaptation.
Research compares hot tubs, dry saunas, and infrared saunas for health benefits. Hot water immersion boosts core temperature, improving circulation, blood pressure, and immune response. Exercise is key, but heat therapy offers an alternative.
Study in Indonesia uses DNA sequencing to track antibiotic-resistant E. coli in abattoir wastewater and rivers, revealing potential spread routes and highlighting the urgency of enhanced surveillance.
High insulin resistance (TyG index) may flag early Alzheimer's patients at 4x greater risk of rapid cognitive decline, offering new treatment possibilities. Metabolic stress is key.
Scientists extracted asperigimycins from Aspergillus flavus, a fungus, showing potential against leukemia cells. Bioengineered fungal RiPPs disrupt cancer cell division with high specificity, equalling FDA drugs.
Study shows higher linoleic acid (omega-6 fat in seed oils) is linked to lower inflammation and better cardiometabolic health, challenging claims that seed oils are harmful.
Study reveals moderate-high fruit intake linked to reduced abdominal adiposity in US children (8-11). High fruit consumption is associated with improved dietary fiber and lower saturated fat.
New Northwestern algorithm improves fitness tracker accuracy for individuals with obesity (95% accuracy). Corrects energy burn miscalculations. Enables better health insights and personalized interventions.
MIT researchers model human decision-making in complex tasks, revealing a flexible use of hierarchical and counterfactual thinking strategies influenced by memory and cognitive constraints, mirrored in AI.
Research links body composition (fat mass, BMI) to pelvic floor disorders in middle-aged women, especially stress urinary incontinence. Lifestyle choices impact risk. Accurate measurements are key.
