The effects of ultra-fast lasers that can change material states in attoseconds are finally understood, thanks to new Israeli ...

The synthetic dye used, called tartrazine, absorbs long-wave ultraviolet light (UV-A ... into the human body to turn it temporarily transparent, according to the researchers.

For several years now, scientists have been using lasers to control the properties of matter at extremely fast rates: during one optical cycle of a light wave. But because these changes occur on the ...
