Mosquitoes' Bloodsucking Tubes Could Enable High-Definition 3D Printing

In a redeeming development for one of nature’s most universally denounced pests, researchers from McGill and Drexel Universities have discovered that mosquito stingers might one day be used for high-definition 3D bioprinting. Reported in the journal Science Advances, the findings demonstrated how the needle-like structure, called a proboscis, that mosquitoes use to extract blood, when repurposed as a tip for a 3D printer, can extrude lines finer than a human hair — surpassing commercially available 3D printing tips.
