Interesting facts about radio

116 years ago in this very auspicious day May 7 great inventor Popov created the first radio. Needless to say how much the invention of radio and irrevocably changed the history of human civilization. Forerunner of modern radio, mobile phones, televisions, radio telescopes and a bunch of other useful things, without which today's man as without hands. To pay tribute to the history of the invention of radio, I decided to compile some of the interesting facts of the radio.

Congratulations, friends!

Recently a group of biophysicists from Northeastern University in Boston have discovered how the so-called "radio bacteria." In his studies, scientists rely on the fact that bacterial DNA is in most cases a closed loop. And it from atom to atom can "run" electron. As quantum particle, the electron when moving will take on different values ​​of the energy that is moving between the energy levels, while radiating energy. The frequency of such "jumps" and will correspond to the frequency of radiation.

According to calculations Uedoma Allen, head of the research group, the frequency of the electron radiation while moving around the ring of DNA corresponding to 0, 5, 1, 1, 5 kHz. Note that the frequency of these signals is previously registered in Escherichia coli.

The problem, however, is the fact that while the model suggests that certain bacteria can produce radio waves, there is no evidence that such radio wave is actually used as a means of communication. And this is a new subject for research.

A new study by researchers from Boston probably inspire scientists to look at the subject more deeply. Most importantly, it established that the bacteria lack the means to generate radio signals.
