Molecular Motors Do Ballet

first_imgScientists at University of Illinois studied dynein and kinesin – the tiny molecular trucks that ferry cargo inside the living cell – and found that they are not just individualists: they cooperate in a delicate yet effective performance.    Some scientists had thought that the two machine types, which travel in opposite directions, were involved in a constant tug-o’war with each other.  Instead, reports the university’s news bureau, “The motors cooperate in a delicate choreography of steps.”    Using high-speed imaging techniques, they determined that “multiple motors can work in concert, producing more than 10 times the speed of individual motors measured outside the cell.”  The machines move by “walking” on rails called microtubules in steps 8 billionths of a meter at a time.  The team is measuring the force produced by the motion to “further understand these marvelous little machines.”  There was no mention of evolution in the report.Someone should put an animation of these machines to the Blue Danube Waltz.  It would be quite a show.  Darwinists could be allowed to buy tickets as long as they do their smoking outside.(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more
