As we age, our immune system doesn’t remain as sharp as it once was. Scientists call this natural decline immunosenescence—a gradual weakening of the body’s defenses that makes older adults more vulnerable to infections, cancer, and slower recovery. Unlike the visible signs of aging, such as wrinkles or gray hair, immunosenescence works silently inside the … Ler mais
The COVID-19 pandemic pushed biotechnology into the global spotlight, with mRNA vaccines saving millions of lives in record time. But this innovation is far from limited to one virus. Today, scientists are exploring how mRNA vaccines beyond COVID-19 could reshape the future of medicine—preventing cancer recurrence, correcting autoimmunity, and even offering broad-spectrum protection against viral … Ler mais
Introduction For centuries, essential oils have been used to protect against seasonal threats and support recovery. Modern research helps explain why: many oils concentrate bioactive compounds—like 1,8-cineole (eucalyptol), carvacrol (oregano), thymol (thyme), and terpinen-4-ol (tea tree)—that exhibit antimicrobial, anti-inflammatory, and stress-modulating effects. When used correctly, essential oils for immune support can complement a healthy lifestyle … Ler mais
