(Phys.org)—Standard evolutionary theories of aging and mortality, being based on mean-field assumptions – which analyze the behavior of large and complex stochastic models by studying a simpler model – conclude that ...
Like the tip of an iceberg, a plant sprouting from the soil barely hints at what lies beneath. At the nexus where roots and soil intersect are thriving microbial communities that play important roles in plant health and growth. ...
