The video below by researchers at the Harvard Medical School and Technion–Israel Institute of Technology shows bacteria break zones of ever increasing concentrations of antibiotics hence demonstrates how bacteria becomes “impervious to drugs”. They are able to
In a creative stroke inspired by Hollywood wizardry, scientists from Harvard Medical School and Technion-Israel Institute of Technology have designed a simple way to observe how bacteria move as they become impervious to drugs. 
Pixels on your gadgets’ screens act as accidental antennae that constantly broadcast screens’ contents. A new paper says the industry needs to fix this security risk before hackers can exploit it.
This hack is possible because the internals of every computing device we own give off electromagnetic radiation. It leaks from the cables and circuitry that carry the display signal from the processor to the screen, and it’s even emitted by the screen pixels themselves. These pixels [Correct? Else what?] become accidental antennas that transmit the display signal into our surroundings—one that a would-be hacker could tune into.
