Our brains may work best when teetering on the edge of chaos. A new theory suggests that criticality a sweet spot between order and randomness is the secret to learning, memory, and adaptability. When brains drift from this state, diseases like ...

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- ...

A new AI tool, AAnet, has discovered five distinct cell types within tumors, offering a deeper look into cancer's inner diversity. This insight could transform how we treat cancer, enabling more personalized therapies that tackle every type of cell . ...

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. . ...
