The researchers hope some day not only to understand viruses better, but to use their tricks for nanotechnology.
Someday man-made motors like these could deliver medicines to patients or power nano-sized machines.
The mechanism generates 20 times the force used by myosin, the motor in muscle.
The article claims that proportional to its size, the motor is twice as powerful as an automotive engine.
A study by Kansas State researchers reported by Phys Org found that more patients recovered from abdominal surgery faster with flowers in the room.
It may be due to more than the psychological benefit of enjoying their colors, fragrances and the get-well wishes behind them: plants also moisten and clean the air of mold and germs.
If you ever find a flying platypus that big, run for cover.
The virus they studied is a bacteriophage a virus that infects and destroys bacteria.
The cutaway diagram of the capsid shows the DNA wound neatly into a fabric-like pattern.
Another analogy is that they work like pistons operating in sequence.
Using ATP energy pellets, they take advantage of electrostatic forces to gently but firmly transfer the DNA strand into the interior, where it coils in an orderly fashion.
