A Gonorrhea-Based Molecular Machine

Gonorrhea , a bacteria that ’s transmitted via sexual intercourse and have unspeakable swelling , may grow out to be the perfect molecular political machine . A group of researchers at Columbia University have announced findings proving that the bacteria can utilize its pili , long filaments that act like limbs , to pull with a force tantamount to 100,000 times its system of weights , and view as it for hour . Here you may see a video of a gonorrhea bacteria pulling on flyspeck , flexible columns around it ( the pili , which you ca n’t see , can stretch up to ten clip the length of the bacterium , and you may see several columns move rather far forth from the bacteria ) . I ’ve tote up some music byHonest Bob and the mill - to - Dealer Incentivesthat might express what the bacterium is on the Q.T. thinking .

This superstrength could make the bacteria the double-dyed ingredient in nanotech devices that have to exert solid pulls on objective around them . Many scientist are already repurposing computer virus and bacterium for use in nanotech simple machine , and now bacteria ’s mega - power may make it the killer app .

According to New Scientist :

scientist knew that Neisseria gonorhoeae bacteria expend “ case four ” pili to crawl along a surface and to attach to cells and infect them .

What they did n’t eff was that these bacterium can bundle pili together to exert long , unassailable pulling . Michael Sheetz and colleagues at Columbia University in New York put the bacterium in a field of study of petite gelatin “ pillars ” and quantify the amount the bacterium could bend them as a way of measuring the force of their drag .

They mostly saw a caboodle of light grab . But one pull in a hundred started out at the same strength as these short drag , then increase in increments about equal to the force of the original clout , as if the bacteria were calling in more individual pili to assist out the first .
