Scientists may one day be able to destroy computer virus in the same way that opera singers presumably shatter wine glass . New inquiry mathematically determined the frequencies at which dim-witted computer virus could be shaken to end .
" The capsid of a virus is something like the shell of a turtle , " said physicist Otto Sankey of Arizona State University . " If the shell can be compromise [ by mechanically skillful vibrations ] , the virus can be demobilise . "
Three-dimensional model of an HIV virus.
Recent experimental evidence has shown that optical maser pulses tune up to the right frequency can kill certain virus . However , locate these so - called resonant frequencies is a bit of tribulation and error .
" Experiments must just stress a blanket variety of conditions and go for that stipulation are find that can lead to success , " Sankey toldLiveScience .
To expedite this lookup , Sankey and his student Eric Dykeman have developed a path to bet the vibrational motion of every atom in a virus eggshell . From this , they can determine the lowest resonant frequency .
As an example of their technique , the team modeled the satellite baccy necrosis computer virus and found this small computer virus resonates powerfully around 60 Gigahertz ( where one Gigahertz is a billion cycle per moment ) , as report in the Jan. 14 issuing ofPhysical Review Letters .
A virus ' death knell
All aim have remindful frequencies at which they naturally oscillate . plunk a guitar string and it will oscillate at a resonant frequency .
But resonating can get out of control . A notable model is the Tacoma Narrows Bridge , which distort and in conclusion fall in in 1940 due to a tip that rocked the bridge circuit back and forth at one of its resonant frequencies .
Viruses are susceptible to the same kind of mechanically skillful excitement . An experimental chemical group led by K. T. Tsen from Arizona State University have recently shown that pulsation of laser lightness can induce destructive vibrations in computer virus shell .
" The estimate is that the time that the pulse is on is about a quarter of a period of a trembling , " Sankey said . " Like force a kid on a swing from rest , one impulsive push induce the virus shaking . "
It is hard to calculate what sort of push will pop a virus , since there can be millions of mote in its shell structure . A direct computation of each molecule ’s movement would take several hundred thousand Gigabytes of calculator remembering , Sankey explain . He and Dykeman have found a method to calculate the resonant frequencies with much less memory .
In exercise
The team plans to expend their technique to study other , more complicated viruses . However , it is still a longsighted way from using this to neutralize the virusesin infect hoi polloi .
One challenge is that laser Light Within can not riddle the skin very deeply . But Sankey imagines that a patient might be hooked up to a dialysis - alike machine that cycle blood through a subway where it can be hit with a laser . Or perhaps , ultrasound can be used alternatively of lasers .
These treatments would presumptively be safer for affected role than many antiviral drugs that can have terrible side - effect . Normal cells should not be impact by thevirus - killing lasersor sound wave because they have reverberating frequencies much lower than those of viruses , Sankey enunciate .
Moreover , it is unlikely that viruses will arise resistance to mechanically skillful quivering , as they do to drugs .
" This is such a new field , and there are so few experiments , that the science has not yet had sufficient clock time to establish itself , " Sankey state . " We remain hopeful but stay on skeptical at the same prison term . "
