Readers here know that we discuss the germicidal aspects of Ultraviolet Irradiation. We know that a specific wavelength of UV damages a microorganism's DNA, which neutralizes the pathogen. We also know that UV does this pretty quickly from lab experiments and published papers. But now we know just how fast it takes.
Researchers have now clocked the effects of UV on DNA in real time. It turns out UV does its work in less than a picosecond.
For more on what a picosecond is, and what this development means to scientist, check out this link to Science A-go-go. It's a great site for science with a little twist!
