Tech & Science Daily: Sound waves help body’s cells ‘regrow’ bone

Rachelle Abbott24 February 2022

There are fresh hopes the advances in tissue engineering developed by RMIT University in Melbourne could help repair bone lost to cancer and degenerative diseases.

Tissue engineering is emerging technology that aims to rebuild bone and muscle by harnessing the human body’s natural ability to heal itself.

Now, the RMIT study published in the journal Small shows stem cells treated with high-frequency sound waves turned into bone cells.

An investigation’s under way into how two high-tech US military Black Hawk helicopters crashed near a Utah ski resort.

A “voice bank” project by Intel, Dell and the MND Association preserves memories and gives motor neurone disease patients the future power of digital speech with artificial intelligence.

The technology was inspired by Stuart Moss, head of IT innovation at Rolls Royce, who lost his father, Brian, to motor neurone disease.

Plus, ethics backlash over urban ‘dark stores’ delivering groceries. A study suggests the brain could “replay” memories in final moments before death. Hear my song...how the brain responds best to the sound of singing. Trawler crews roped in for conservation project investigating sharks and stingrays swimming to Wales. And, out of the doghouse...German shepherd’s kennel struck by meteorite on sale for £150,000.
