Lensfree Ultrawide-field Cell-monitoring range platform based on shadow or LUCAS for short is an incredible new hack by a researcher at UCLA. This quick little hack involving only some wire, a filter, and an LED might revolutionize blood testing. This hacked video camera replaces a unit that is typically the size of a refrigerator and very expensive to run. This is a pretty incredible achievement and ought to serve as inspiration for hackers all everywhere.
