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 ...

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.

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