Scientists Reveal Hidden History of the Modern Strawberry
Researchers used molecular signatures in mobile DNA to trace the evolutionary origins of the cultivated strawberry genome. Polyploid genomes form when entire genomes duplicate and combine through repeated hybridization events. This process has…

A new clue to how the body detects physical force
Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal the brain can interpret as touch. While scientists have long known that a protein called PIEZO2 acts as a key sensor for…
