Japanese researchers have found that vitamin C can thicken skin by switching on genes that boost skin cell growth, helping reverse age-related thinning. It works by reactivating DNA through a process that lets cells regenerate more effectively- ...

Leafcutter ants live in highly organized colonies where every ant has a job, and now researchers can flip those jobs like a switch. By manipulating just two neuropeptides, scientists can turn defenders into nurses or gardeners into leaf harvesters. . ...
