Biological Age
Biological Age Scientific Mechanisms, Measurement, and Implications for Human Longevity** Abstract Biological age (BA) represents the functional and molecular state of an organism relative to its chronological age (CA). Unlike CA, which measures the passage of time, BA quantifies physiological integrity, reflecting cumulative cellular damage, epigenetic modifications, and organ-system performance. Recent breakthroughs in molecular biomarkers—especially epigenetic clocks—have transformed BA from a theoretical construct into a measurable indicator with predictive power for morbidity and mortality. This article reviews the mechanistic basis of BA, current measurement systems, and potential applications within preventive medicine, precision health, and longevity sciences.

Role of Microorganisms in Environmental Balance
Role of Microorganisms in Environmental Balance Abstract Microorganisms; bacteria, archaea, fungi, algae, and viruses, form the invisible foundation of Earth’s ecosystems. They drive biogeochemical cycles, maintain soil fertility, purify water, degrade pollutants, and support plant and animal life. This review explores the ecological significance of microorganisms, highlighting their contributions to nutrient cycling, climate regulation, waste decomposition, symbiotic associations, and bioremediation. Without microbial activity, life on Earth and environmental sustainability would collapse.
