[00:00:00]The world's least painful needle was designed by copying a bee's stinger.

[00:00:04]A bee stinger has serrated edges, tiny barbs that cut [music] through tissue with minimal resistance.

[00:00:10]Each barb is angled to reduce friction as the stinger penetrates.

[00:00:15]Researchers at Kansai University in Japan used [music] this design to create a hypodermic needle with micro serrations.

[00:00:22]In tests, it caused significantly less pain than conventional smooth needles.

[00:00:26]The bee evolved this design to inject venom efficiently.

[00:00:30]Humans copied it to inject medicine painlessly.
