Subjected to high-frequency sound waves, stem cells extracted from fat tissue grow into new bone cells.
Audible sound waves are useful too, as this latest innovation from a London-based designer shows: her portable speaker doubles as an air purifier.
Internal ventilators along with the music’s waves remove harmful particles from the air and drive them into a special filter inside. The filter’s microscopic structure, formed by a laser, particularly captures small to medium-sized particles.
A display, meanwhile, keeps track of air quality levels. The patent-pending mobile speaker has three modes of operation, working as an air-purifier, a speaker, or both of these combined.
