A blast of ultrasound waves could rejuvenate ageing cells

Treatment with low-frequency ultrasound has restarted cell division in ageing human cells and improved physical performance in old mice

Low-frequency ultrasound appears to have rejuvenating effects on animals. As well as restarting cell division in ageing human cells, it has reinvigorated old mice, improving their physical performance in tests such as running on a treadmill and making one old mouse with a hunched back move around normally again.
