The repeated weak slapping of protein surfaces against one-another is the critical first step in a chain of events that rule all subsequent cellular behavior. But this vital exchange between single...

Regular physical activity really does boost immune system in older men

...mostly men, are fond of saying something along the lines of, "I feel like a 25-year-old." As it turns out, judging by the reaction strength of their immune system to an unknown, but harmless, protein antigen, it's possible for men over 70 to mount an immune response similar to that produced by much younge...
