Danielle Zurovcik, a doctoral student at MIT, created a hand-powered suction-healing system that speeds up healing of open wounds.
To put the awesomeness of this invention in context, traditional suction-healing systems cost at least $100/day and need to be recharged every six hours. This one costs $3 to make, sustain and use.
That’s a godsend for poor places and countries. So why aren’t we seeing more of these things being invented?
