A new study describes a successful experiment where researchers were able to engineer fruit flies’ hearts into being light sensitive and thus, could control the beats with the flashing pulses of a laser.
Scientists have been able to successfully control a fruit fly’s heartbeat with a laser.
The process is akin to a pacemaker regulating cardiac movements through electrical stimulation except it uses light instead.
It’s part of a growing field called optogenetics where cells are engineered to become s
