# s-nanotech: displayed by an electronic tattoo

<< A new temporary "electronic tattoo" (..)  that can measure the activity of muscle and nerve cells (..) is poised to revolutionize medicine, rehabilitation, and even business and marketing research. >>

<< The tattoo consists of a carbon electrode, an adhesive surface that attaches to the skin, and a nanotechnology-based conductive polymer coating that enhances the electrode's performance. It records a strong, steady signal for hours on end without irritating the skin. >>

<< The electrode (..)  may improve the therapeutic restorationof damaged nerves and tissue -- and may even lead to new insights into our emotional life. >>

# s-phys: "entanglement entropy of a qubit", the begin ...

<< All systems are fundamentally quantum systems (..) but the means of describing in a quantum sense the chaotic behavior of, say, air molecules in an evacuated room, remains limited >>

<< To investigate, [AA] devised an experiment using three quantum bits, the basic computational units of the quantum computer >>

<< By manipulating these qubits with electronic pulses, [AA] caused them to interact, rotate and evolve in the quantum analog of a highly sensitive classical [chaotic] system >>

<< The result is a map of entanglement entropy of a qubit that, over time, comes to strongly resemble that of classical dynamics — the regions of entanglement in the quantum map resemble the regions of chaos on the classical map >>

# e-sec: brainjacking in medical implants

<< Here  are  some  real  examples  of  what  can  be  achieved  if  you  have  access  to  somebody’s  DBS [Deep Brain Stimulation] electrodes.  You  can  induce  mania,  hypersexuality,  and  even  pathological  gambling.  You  can modify  emotions.  Patients  undergoing  DBS  therapy  have  sometimes  experienced  pathological crying  and  inappropriate  laughter,  "likely  due  to  off-target  stimulation,"  says  the  paper.  Strong sensations  of  fear  and  panic  have  also  been  observed. >>
