If wind turbines clatter and whistle too loudly, they are only permitted to operate under partial load to protect the local residents -- but this also means a lower electricity output. An active damping system cancels out the noise by producing counter-vibrations.

Compared to humans, bacteria have a much tidier genome. The tiny microorganisms pack their genes closely together, and don't carry around a lot of extraneous DNA, so-called junk DNA that fills in the gaps between genes. Some 90 percent of the complete genome sequence of the bacteria E. coli contains sequences of DNA that code for protein, while 90 percent of the human genome is non-coding junk DNA.
