It is well known that gene expression becomes disarrayed in cells in old tissues. Mechanisms controlling the structure of nuclear DNA become dysfunctional, and that can unleash all sorts of errant protein production by allowing the machinery of gene expression to reach sections of the genome that are normally folded […]

Salk researchers pinpoint a sound-sensitive mammalian protein that lets them activate brain, heart or other cells with ultrasound. Salk scientists have engineered mammalian cells to be activated using ultrasound. The method, which the team used to activate human cells in a dish and brain cells inside living mice, paves the […]
