Scientists jump-start two people’s brains after coma

[–] • 0 pt

"Monti said the device is safe because it emits only a small amount of energy, less than a conventional Doppler ultrasound. "

That's like saying "it as safe a a dental xray" which we now know are leading causes of brain cancer.

It's a good result in a coma patient but people should always be cautious about any form of energy directed at or in your body.

ultrasounds can harm fetuses for example.

you don’t have to be able to sense something to be harmed by it. for example a uv laser cant be seen but can easily blind you.

energy is energy.
