You’ve probably already guessed it - no it doesn’t make a female pregnant, instead, this biohybrid sperm microbot will hopefully one day deliver anti-cancer drugs to tumours in the female reproductive tract. The microbot consists of sperm from a bull combined with a plastic, 3D-printed microstructure with a magnetic coating allowing researchers to steer the robot to the target. When the bot hits the tumour, four arms on the microstructure automatically bend and release a sperm cell. This penetrates the cancer cells and delivers its medical solution. #WeWillBeatCancer
