Scientists Learning How to Harness Cellular Trucks

In an article that blurs the line between biology and technology, a press release from the Max Planck Institute (see EurekAlert for English translation) described the amazing performance of the nanoscopic trucks that ride the cell’s microtubule superhighways.  Kinesin and myosin motors, fueled by ATP, usually “sprint” on the trackways for short distances, but working in concert like a relay team, can run marathons for centimeters or even a meter.  This is especially important in neurons, some of which can have axons a meter long – in our spinal cord.  The scientists are learning as much as they can about these molecular motors in order to harness the technology for directed chemical reactions and biomimetic applications. The Energizer Bunny would face stiff competition on this scale: the article comments, “in contrast to human sprinters, molecular motors don’t get tired.” 

There is no mention of evolution in this article.  This “motor-driven active transport” bears the hallmark of intelligent design and coordinated function.  Darwinism is utterly useless for this cutting-edge scientific work that holds promise for spinoff technologies that could greatly improve our lives and understanding of nature’s workings.  Compare that with the next entry below.
