Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species。 Even more surprising, some show little sign of physical decline as they age。 Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helpin
Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils。 Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilient。 Greenhouse and field tests showed healthier plants and higher yiel
