Johns Hopkins scientists recently conducted an unusual experiment: They took a bunch of blood, attached it to a drone, and sent it flying.

This was not just a scientistโ€™s weird idea of fun. The researchers were looking for a better way to transport biological samples, something thatโ€™s of special concern in countries without developed road systems or robust infrastructure. Making the problem even thornier is the fact that blood is finicky. It canโ€™t even be sent through some hospitalsโ€™ internal pneumatic tube systems, because the stopping-and-starting might destroy cells or cause it to coagulate.

The benefit of drones is that theyโ€™re light, swift, and easy to control. And so the Hopkins team partnered with scientists at Ugandaโ€™s Makerere University to see if this idea might actually work. They took blood samples from a few dozen healthy people at Johns Hopkins Hospital and then drove them out to a drone test zone. Then, the samples were zoomed around in the air for anywhere between 6 and 38 minutes. Then they were taken back to the hospital where they underwent the 30 most common lab analyses.

โ€œThe flight really had no impact,โ€ said experiment leader Timothy Kien Amukele, a pathologist at the Johns Hopkins University School of Medicine.

Bring on the drones!
