Zap those viruses with lasers!

Researchers Kong-Thon Tsen, a physics professor at Arizona State University, and his son Shaw-Wei Tsen, a pathology student at John Hopkins, have found a way to destroy this protective sheath without harming normal cells.

The secret is a device known as an Ultrashort-Pulse (USP) Laser.  A harmless laser pulse, 1/40th of the level destructive to human cells, was aimed a Tobacco Mosaic Virus.  The laser destroyed the virus, leaving behind only a mucus-like mess of molecules.

The laser releases energy in pulses in the femtosecond range; a femtosecond being a millionth of a nanosecond--10-15 seconds.

The super-fast pulses are tuned to the resonant frequency of the virus protein and causes it to vibrate, with each pulse adding to the vibration.  Eventually the vibration overcomes the bonding energy of the protein's bonds and the protein structure disintegrates, shattering into harmless component atoms and molecules.

Very cool. Someday, such a technology may be used for cancer treatments as well.

Now this is revolutionary, and a true solution in actual "combating" of viruses....why? Well, imagine a "nano-tank" or "nano-mech" equipped with these "nano-lasers" and injected into your bloodstream...they will then hunt down the viruses like antibodies and mechapulvurize them to oblivion! Hihihi

^^ i used to play this pc game, where you pilot a vehicle that is miniaturized and inserted in the bloodstream, where your objective is to destroy viruses. just like in the martin short and meg ryan movie.
it puzzles me how women seem so fragile but they can hurt men more than they realize it.

i will give you 2000 czech crowns...

At last! A cure for the common cold!!! If it works it's the greatest scientific breakthrough in history!

@Simbadda
I think i've played that too. You're a flat concave thing that spits out molecule strings right?
Truly superior pilots are those who use their superior judgment to avoid those situations where they might have to use their superior skills.
